Book Description

Content and media asset management systems are core back office applications of the modern day broadcaster, yet there is little information available on the control and management of these systems and how content can be delivered over a variety of different channels: television, iTV, internet, webcasting, mobile phones and wireless PDAs. This book explains the potential for applying asset management systems to content creation models for distribution over a variety of outlets and the benefits gained from increased efficiency and lowering of costs.

Taking an unbiased view and focusing on core principles rather than specific systems, David Austerberry presents the business case for digital asset management systems, demystifies some assumptions regarding the technology and provides a thorough introduction to the system components required, such as indexing, searching, middleware, database and rightsmanagement and web portals.

*Demystifies the underlying technologies of media asset management
*Explains the processes and operations involved in setting up a media asset management system
*Provides an unbiased view of the leading systems

3-0 out of 5 stars Not enough
This is a fine book if you just want a general overview of RF probe. It lacks detail and in-depth coverage. You may find a few helpful things in it but it is far from being a great book on the subject.

4-0 out of 5 stars A Beneficial Text for RF Engineers
Measuring RF characteristics on die as well as packaged devices requires much attention to detail, from the theoretical to the practical application standpoints. Mr. Wartenberg's book takes into account all of these considerations in this well written book that contains many useful equations as well as practical hands-on tips.

This book provides information on RF die and package probing that the entry level as well as experienced RF Design, Test and Product Engineering professional will find useful.

Additionally, this text can be used as both a text and a reference book. It provides many references for the reader to investigate topics in even more detail than the extensive writings provided in this book. A must read for anybody who probes and measures die and/or packages containing RF devices.

4-0 out of 5 stars Valuable advice for RF test engineers
Those experienced in the microwave industry will tell you that RF testing is a very subtle art and highly sensitive to environment and test conditions. It is far from "mature" as one reviewer puts it. Greater complexity and integration in RF IC's are placing greater demand for complex probe design. It is for these reasons that there are few books that cover this area. Scott Wartenberg's book does a great job in addressing this complex field and offers valuable insight together with a wealth of real bench experience. The latter is very useful for young and seasoned engineers alike. You will find many "nuggets" of wisdom that would aid and correct your RF test methodology.

4-0 out of 5 stars New to microwave IC measurements? This book is for you.
This text provides an excellent introduction to many of the important aspects of measuring high speed ICs. Topics include understanding microwave measurements, calibration, practical issues pertaining to microwave and millimeter wave probing, test fixtures and on-wafer characterization. I would highly recommend this book to anyone who is looking to enter the field of microwave and millimeter wave IC measurement and characterization.

Additionally, for the many engineers working in high speed optical communications (i.e. OC-192, OC-768 ...) that do not have a microwave background, this book will provide you with insight into how high speed interfaces work and what the important issues are. Many excellent references are given that will help you to probe further into any of the topics presented.

2-0 out of 5 stars Nice try, but a bit shallow
Microwave wafer probing has been around since the mid-80's and is relatively mature, with commercial products that satisfy most needs. This work attempts to summarize information from manufacturers' applications notes, trade magazines, and professional publications. It provides little (if any) original content. The greatest strength of this book is the extensive list of references.
The content was disappointing however. The book stays at the surface of the subject. When it occasionally attempts depth it is of questionable accuracy. Knowledgeable readers will identify minor quibbles to completely incorrect statements. There are also a few discussions that make no sense, use unusual/confusing terminology, or take the reader down a path to incorrect interpretations of the meaning.
The "packages" content seems to be an afterthought, in some sections the text is written solely as if the book was only about die measurements.
To summarize: This is a useful read even for experienced microwave probers, but read with caution. The content is not authoritative and should be verified prior to trusting. ... Read more

2-0 out of 5 stars WAAAAY TOO TECHNICAL
Too much time spent on the mathematics of sound transfer and acoustics. Not enough on how to build the studio. Could not find a "complete parts list" for any of the plans. This is not for someone looking to build a simple studio. Very technical and boring.

4-0 out of 5 stars great advice, but dont stop here
as another reviewer says, this appears to be the previous edition of what is currently titled "how to build a small budget recording studio....". also, as another reviewer has noted, you dont have to read it in order -- each example project its its own chapter with its own self-contained presentation. each example does stress diffferent design goals that translate to different acoustic treatments.

its a little annoying that every page seems to be an advertsemen for an rpg product. this is mitigated by the author's inclusion of journal and patent references that tell you everything you need to know to build these treatments yourself if you like. or if your budget doesnt allow for the beautiful wood forms from rpg, just take the keywords and run -- diffusor, absorber, abfussor -- and its easy to find someone besides rpg that makes the things using less expensive materials.

i enjoyed the book enough that i'm ordering the next edition. i also recommend his book on stereo theory if you want an overview of the psychoacoustics involved.

2-0 out of 5 stars A poorly structured book
The subject of the book looks promising, but the author might better have warned that the book is not conceived to be read from the beginning to the end, but directly jumping to the chapter that relates to the specific type of construction that you want to know more about. Otherwise, you find the same concepts explained again and again... and surprisingly, half way through the book it gets organized and the last chapters explain the basic concepts (again). In my opinion, a better structure would have reduced the lenght of the book to a half and provided a clearer understanding of the valuable information that it contains.

3-0 out of 5 stars The new edition is Greatly Improved
The new edition is called "How to Build a Small Budget Recording Studio from Scratch ... , With 12 Tested Designs" is much more accessible. Both editions cover the same area with the same info, so I don't know why they are continuing to publish this old edition in parallel with the new.

3-0 out of 5 stars On What Budget?
It's a good book with a lot of good information, but when it comes down to it, most of what it's advising you to do for sound treatment involves buying several $200-$300 units, with no instructions on how to build them on your own. It seems like the title could be "Sound Studio Construction on a Healthy Budget". ... Read more

Among network designers and administrators, wired Ethernet is a known quantity. Plenty is known about how to build good twisted-pair network infrastructures, how to keep them secure, and how to monitor their excess capacity. Not so for the wireless Ethernet networks (built around the IEEE 802.11x standards)--these hold much more mystery for even experienced network designers. 802.11 Wireless Networks: The Definitive Guide aims to codify the body of knowledge needed to design and maintain wireless local area networks (LANs). The authors succeed admirably in this, covering what installation and administration teams need to know and digging into information of use to driver writers and others working at lower levels.

The only significant detail that's been excluded has to do with security--a notorious weak point of 802.11x LANs. The authors cover the feeble but widely used Wired Equivalent Privacy (WEP) authentication protocol in detail and devote another whole chapter to 802.1x, which is an emerging authentication scheme based on Extensible Authentication Protocol (EAP). The author has considerable skill in communicating information graphically and does a great job of using graphs to show how communications frequencies shift over time and how conversations among access points and network nodes progress over time. This is indeed an authoritative document. --David Wall

Topics covered: How IEEE 802.11a and 802.11b wireless networks (also known as WiFi networks) work, and how to configure your own. The framing specification is covered well, as are authentication protocols and (in detail) the physical phenomena that affect IEEE 802.11x radio transmissions. There's advice on how to design a wireless network topology, and how to go about network traffic analysis and performance improvement. ... Read more

5-0 out of 5 stars A great look into the world of 802.11
With the advent of wireless networks and the going interest in faster and more secure networks the 802.11 standard is fast becoming one of the most talked and studied topics in networking today. With the release of this book you have a great first hand look at what you can expect and how it all works.

In just over 450 pages the author has detailed out the way wireless is meant to be setup and configured. The documentation is well researched and judging by the content the author has certainly shown his expertise.

Starting off the book is an overview into the world of 802.11, and for someone like me with limited knowledge this was a great way to be introduced to the material. The author goes into Frame breakdown, encryption, use with Windows and Linux, analyzing, tuning and PCMICA.

Overall there is information from setup to deployment and just about everything in between, including the administration of the 802.11 networks. This becomes a very handy reference manual to have around - excellent job!

5-0 out of 5 stars If you get one WLAN book, make it this one!
I literally have the vast majority of books in print right now on wireless networking/802.11 and I can honestly say that this book is one of the top three (3) that you should have. I have taken many informational and certification classes on Wi-Fi or the 802.11x standard. The vast majority of them come right out of this book! It is written in a style that, even though it is highly technical at times, it is an easy read. Plus, this is all the technical information you could ever want and more! This will be a well and oft used reference if you work in this field. Like I said, if you have to get just one WLAN book, get this one!

4-0 out of 5 stars An Excellent Choice
I really liked this book. It helped me write my research paper for UMUC MSIT 640 - Data Communications and Networks. The book has a lot of useful information. It has a good section on the different types of antennas. The book has a lot of Acronymns that are clearly explained. Generally, I think all oreilly books are very good. The book talks a lot about the wireless LAN. It includes many disadantages and advantages. The book also has a lot of useful diagrams. I would recommend this book to anyone who wants to learn about the wireless LAN.

4-0 out of 5 stars The best reference in this field till now
It is organized well according to the IEEE 802.11 version of 1999. The concept of WLAN is clarified clearly.
But the content of 802.11a seems lacking for a better understanding. Several chapters introducing the products from vendors are useless to me.
I hope the next edition will give more description on 802.11a, 11e and 11g.

5-0 out of 5 stars Very Comprehensive; Valiant Effort.
Recently I've been designing a system to run atop 802.11b radios and this book has served as an excellent introduction to the 802.11b standard. For example, Gast's description of spread-spectrum radios, chipping, and OFDMA radio systems is a broad overview without going into excessive mathematical formulas and it gives a non-RF engineer a basic understanding of what are the issues underlying each of the 802.11 radios of today.

I found myself reading a chapter of this book, and then looking at the 802.11b standard itself (now available free on the website ieee.org) for more detailed information. I found only a couple of minor errors in this book. This book serves as an outstanding introduction to the protocol standard, which is large and which contains little or no practical information for the practitioner. However, I did also use Radia Perlman's book on Routing in conjunction with this book to help me understand IEEE 802.1 issues.

Gast attempts to be a be-all and end-all book for everyone. For example, he attempts to describe all 802.11 RF modulation schemes. He attempts to give a full description of all the packet formats. He attempts to describe which cards are based on which baseband (Intersil or Orinoco). This stuff is changing very fast but he gave it his best shot, and its very important to people installing *NIX drivers. He attempts to tell you how to set up an 802.11 Ethereal packet sniffer. All of his information is invaluable to anyone setting up 802.11b on any flavor of UNIX or Linux. Anyway, he makes a really valiant effort and I've never seen a networking book try to play in all 4 spaces at once - RF Theory, Network Protocols, Hardware Selection, and Practicum - all at the same time. He should be applauded for this attempt.

I have not found a book that is nearly as comprehensive (6/2003) and I've lent this book to at least 5 other people, most of them PhD's or VP's in EE or CS and/or wireless communications. ... Read more

5-0 out of 5 stars Most complete RBAC reference
The three authors are leaders in RBAC research and development, making this book one of the most authoritative and complete references to RBAC.

Chapters 1 through 3 give a solid foundation for understanding RBAC and how it evolved, starting with an introduction, an exhaustive survey of access control methods needed to fully understand the evolution, and a solid and detailed overview of RBAC itself.

In the subsequent chapters each aspect of RBAC is covered in depth. Topics include role hierarchies, separation of duty policies, administration, integrating RBAC into existing infrastructures, and migration to RBAC. In addition, there are chapters on related topics that give this book wide scope - "Using RBAC to Implement Military Policies" shows how to implement multi-level security models with RBAC. This information uses military policies, but the material is also of interest to any commercial organization seeking tightly integrated access controls and a high security posture. The chapter on the proposed NIST RBAC standard also covers key items of interest, including Common Criteria RBAC protection profiles and other conformance issues. There are also chapters on RBAC research and prototypes, and commercial products.

While this book is well written and uses illustrations to impart key concepts, you will need to be conversant with set theory in order to get the most from it, as well as understand RBAC itself. If you are a bit rusty I recommend refreshing your skills before diving into this book.

If you want to explore RBAC and the work of each of the authors visit NIST Computer Security Division and Computer Security Research by pasting the ASIN, B0001O48Y4, into the search box, selecting all products and clicking GO. Once you are on the site you'll find the RBAC section under Security Research/Emerging Technologies->Authorization Management and Advanced Access Control Models (AM&AACM) link. ... Read more

Book Description

The ultimate practical resource for today's RF system design professionals
Radio frequency components and circuits form the backbone of today's mobile and satellite communications networks. Consequently, both practicing and aspiring industry professionals need to be able to solve ever more complex problems of RF design.
Blending theoretical rigor with a wealth of practical expertise, Practical RF System Design addresses a variety of complex, real-world problems that system engineers are likely to encounter in today's burgeoning communications industry with solutions that are not easily available in the existing literature. The author, an expert in the field of RF module and system design, provides powerful techniques for analyzing real RF systems, with emphasis on some that are currently not well understood. Combining theoretical results and models with examples, he challenges readers to address such practical issues as:
* How standing wave ratio affects system gain
* How noise on a local oscillator will affect receiver noise figure and desensitization
* How to determine the dynamic range of a cascade from module specifications
* How phase noise affects system performance and where it comes from
* How intermodulation products (IMs) predictably change with signal amplitude, and why they sometimes change differently
An essential resource for today's RF system engineers, the text covers important topics in the areas of system noise and nonlinearity, frequency conversion, and phase noise. Along with a wealth of practical examples using MATLAB(r) and Excel, spreadsheets are available for download from an FTP Web site to help readers apply the methods outlined in this important resource.

Book Description

"...Ben has been the world-wide guru of this technology, providing support to applications of all types. His genius lies in handling the extremely complex mathematics, while at the same time seeing the practical matters involved in applying the results. As this book clearly shows, Ben is able to relate to novices interested in using frequency selective surfaces and to explain technical details in an understandable way, liberally spiced with his special brand of humor... Ben Munk has written a book that represents the epitome of practical understanding of Frequency Selective Surfaces. He deserves all honors that might befall him for this achievement." -William F. Bahret.

Mr. W. Bahret was with the United States Air Force but is now retired. From the early 50s he sponsored numerous projects concerning Radar Cross Section of airborne platforms in particular antennas and absorbers. Under his leadership grew many of the concepts used extensively today, as for example the metallic radome. In fact, he is by many considered to be the father of stealth technology.

"This book compiles under one cover most of Munk's research over the past three decades. It is woven with the physical insight that he has gained and further developed as his career has grown. Ben uses mathematics to whatever extent is needed, and only as needed. This material is written so that it should be useful to engineers with a background in electromagnetics. I strongly recommend this book to any engineer with any interest in phased arrays and/or frequency selective surfaces. The physical insight that may be gained from this book will enhance their ability to treat additional array problems of their own." -Leon Peters, Jr.

Professor Leon Peters, Jr., was a professor at the Ohio State University but is now retired. From the early sixties he worked on, among many other things, RCS problems involving antennas and absorbers.

This book presents the complete derivation of the Periodic Method of Moments, which enables the reader to calculate quickly and efficiently the transmission and reflection properties of multi-layered Frequency Selective Surfaces comprised of either wire and/or slot elements of arbitrary shape and located in a stratified medium. However, it also gives the reader the tools to analyze multi-layered FSS's leading to specific designs of the very important Hybrid Radome, which is characterized by constant band width with angle of incidence and polarization. Further, it investigates in great detail bandstop filters with large as well as narrow bandwidth (dichroic surfaces). It also discusses for the first time, lossy elements used in producing Circuit Analog absorbers. Finally, the last chapter deals with power breakdown of FSS's when exposed to pulsed signals with high peak power.

The approach followed by most other presentations simply consists of expanding the fields around the FSS, matching the boundary conditions and writing a computer program. While this enables the user to obtain calculated results, it gives very little physical insight and no help in how to design actual multi-layered FSS's. In contrast, the approach used in this title analyzes all curves of desired shapes. In particular, it discusses in great detail how to produce radomes made of FSS's located in a stratified medium (Hybrid Radomes), with constant band width for all angles of incidence and polarizations. Numerous examples are given of great practical interest. More specifically, Chapter 7 deals with the theory and design of bandpass radomes with constant bandwidth and flat tops. Examples are given for mono-, bi- and tri-planar designs. Chapter 8 deals with bandstop filters with broad as well as narrow bandwidth. Chapter 9 deals with multi-layered FSS of lossy elements, namely the so-called Circuit Analog Absorbers, designed to yield outstanding absorption with more than a decade of bandwidth.

      3-0 out of 5 stars Good book of wireless tips
      I'll have to disagree a bit with reviewer Pablo D. The book is broad and shallow, but I think it appeals to more than just the raw beginner. I found a number of tricks (hard to call them "hacks") in the book that have been useful.

      1-0 out of 5 stars Very broad, very poor. Only for the very beginner
      This is the kind of book that will tell you that a packet-capture program is a "hack"... Spends a lot of pages describing common features or well-known programs (Kismet, NetStumbler).
      The book tries to cover Windows, Linux and MacOS and achieves that in a very low degree.
      Save your money, everything on this book can be found on the internet, with even a better structure than the "index style" this book has ("Hack#1", "Hack#2" and so on).
      Very disappointed. Makes me wonder if other posts came from O'Reilly itself.

      5-0 out of 5 stars For the serious wireless freak
      This is an amazing book about wireless. It's coverage of everything from the operating system level stuff, to drivers, to cards, to hacking cards, to building your own antenna, to doing shotgun wireless is just incredible. If you are a serious wireless junkie you will love this book. For the casual coffee shop surfer, this is probably not the right book, but you probably don't have any issues with wireless anyway.

      5-0 out of 5 stars All things wireless....
      Rob Flickenger has done it once again and this time he actually used the word "hacks" in his latest book on wireless networking, fittingly entitled, Wireless Hacks: 100 Industrial-Strength Tips & Tools. The explosion and growth of wireless technology has a familiar feeling that takes one back to version 1.0 of web browsers and dialup connections that opened our eyes to a whole new world. From, imagine... I can see inline graphics, to, wow... I am streaming live content while sitting on my deck enjoying a cool one!

      Wireless Hacks isn't a traditional book, but as the title implies, it is composed of one hundred tips, tricks, suggestions, DIYs (do it yourself), tools or simply *hacks* regarding all things wireless. Open it up to the index and browse for something that catches your eye. This book really is not meant to be read front to back although you can if you want. I found myself using my trusty old magazine technique of folding over pages of things I wanted to try out or that were quick solutions to current problems. There are enough nuggets in this book to make it worthwhile even for wired users (check out #36 Estimating Network Performance or all of Chapter 3: Network Monitoring).

      Glen Flieshman mentions in the foreword that "... Rob Flickenger is an early adopter's early adopter" which sums up the value Rob brings to the table. He is a wireless pioneer paving the way to unplugging but yet staying connected and the really cool thing is that he is willing to share.

      4-0 out of 5 stars For the tinkerer in you
      An interesting amalgam of software and hardware tips. The author clearly loves to tinker, as seen by his description of how he and friends put together a waveguide antenna built around a Pringles can. Perusing the book seems to give some of the flavour of the Homebrew Computer Club in San Francisco during the 1970s, when the PC revolution was gestating.

      To some (many?) of you, the do-it-yourself ethos of this book may be its greatest allure. Flickenger reinforces this with many examples of analysis programs contributed by enthusiasts, often with source code available for your modification.

      If indeed you seem attracted, do not tarry. Flickenger may not explicitly state this anywhere in the book, but it really describes a field and hobby that will rapidly make much of the book obsolete. Chances are, in a few years hardware will be standardised by a few major manufacturers, and most operating systems will have all the necessary wireless software. So if you want some fun, perhaps now is the time. ... Read more

5-0 out of 5 stars Very well done: intelligent and complete
This book helped me a lot to sum up all the different technologies that are today available in the telecom industry. Of course I heard of lots of them during my studies but we can't see all of them and in a such exhaustive manner as the author did. I especially learned a lot with the first part as deregulation is a very new issue in France.

5-0 out of 5 stars Very thorough and well laid out.
A very informative reference. I have found myself sharing this with those outside and inside the industry who have been able to read this and better understand the technology and its very profound evolution and impact to our society. I was fortunate enough to have had the author as an instructor. We were the first class to have the published version taught to us and those who had already had the course rushed to purchase it when it was released due to the very nature of both the teacher and the content of the book. Thank you Professor Cole and I am very much looking forward to your next publication.

5-0 out of 5 stars One of the best organized and intelligent books out there.
Hi. I am active duty in the USAF, and work in communications and I can confidently say that telecommunications, by Marion Cole, is by far the best book on the subject that I've come accross. The book is very well organized and the content covers everything that one who deals with telecommunications would need. From the history of telecommunications to late breaking technologies. This book covers every aspect of analog and digital technology, from the simple telphone, to multiplexing phone and data lines over fiber using Wave Division Multiplexing. I personally recommend this book to anyone who would like to learn the technology or just to brush up on their skills. This book is a number one choice!

5-0 out of 5 stars Very Informative
This book covers many topics in telecommunications in an easy to understand format. It is written by someone who knows the industry, because he has lived it. I highly recommend this book to anyone that has a desire to understand the details of how various telephone technologies work. ... Read more

Strategies and solutions for successful VoIP deployments

Justify your network investment

  • The step-by-step approach to VoIP deployment and management enables you to plan early and properly for successful VoIP integration with your existing systems, networks, and applications.
  • The detailed introduction offers a common grounding for members of both the telephony and data networking communities.
  • IT managers and project leaders are armed with details on building a business case for VoIP, including details of return-on-investment (ROI) analysis and justification.
  • A VoIP deployment is presented as a major IT project, enabling you to understand the steps involved and the required resources.
  • The comprehensive look at quality of service and tuning describes when and where to use them in a VoIP deployment. These are often the most complex topics in VoIP; you'll get smart recommendations on which techniques to use in various circumstances.
  • You learn how to plan for VoIP security, including prevention, detection, and reaction.

Voice over IP (VoIP) is the telephone system of the future. Problem is, VoIP is not yet widely deployed, so there are few skilled practitioners today. As you make your move to VoIP, how will you know how to make VoIP work and keep it working well? What changes will you need to make without disrupting your business? How can you show your return on this investment?

Many books contain technical details about VoIP, but few explain in plain language how to make it run successfully in an enterprise. Taking Charge of Your VoIP Project provides the detailed plans you need to be successful in your organization's deployment of VoIP. Through their years of work in the field, authors John Q. Walker and Jeffrey T. Hicks bring a project-oriented approach to VoIP, with much-needed clarity on getting VoIP to work well.

Taking Charge of Your VoIP Project starts with simple concepts, each chapter building on the knowledge from the last. Although not a technical manual, you learn about the standards, such as H.323, G.711, and Real-Time Transport Protocol (RTP), and the implications they have on your VoIP system. Most importantly, you'll gain expert advice and a systematic guide on how to make VoIP work for your organization.

This volume is in the Network Business Series offered by Cisco Press. Books in this series provide IT executives, decision makers, and networking professionals with pertinent information on today's most important technologies and business strategies.

5-0 out of 5 stars Don't Start Without It!
I recently read the book titled "Taking Charge Of Your VoIP Project" by John Q. Walker and Jeffrey T. Hicks. ISBN: 1587200929.
The title is a great reference for understanding VoIP technology and helps identify the many aspects that one must consider for a successful deployment of Voice over IP. Reading this book ahead of time will empower the reader with the lingo, technology and solutions to be effective when leading a team.
The book starts out by giving the reader an understanding of the basic technology concepts surrounding traditional voice networks, or Public Switched Telephone Networks (PSTN) and then goes right into the basic technologies that allow Voice over IP (Data) to be a viable alternative to the traditional phone networks.
Chapter 2, Building a Business Case for VoIP, gives the reader good information to ponder over and helps identify purpose for building a case for a VoIP solution.
The next chapter, "Planning for VoIP" is one of the larger chapters and for good reason. After all, anyone in business knows that planning determines whether the project will go smoothly with little surprise or whether it's a disaster. In this chapter you'll learn about reliability, call quality assessment, and over all VoIP readiness assessment, among other things.
Another great chapter is Chapter 5, "Quality of Service and Tuning". Probably one of the biggest challenges that an organization will face. QoS is challenging due to the complexity of a true end-to-end QoS solution in an already complex data network. Accomplishing QoS requires in-depth knowledge of the existing data network. Furthermore, the communication to others on the team of what it's going to take to get the network "up to snuff" to support VoIP will be a task in and of it self. It makes ATM technology look quite attractive. The chapter has quite a bit of detail; however the authors don't drop the reader over the deep end of the technologies.
I would recommend this book to those that are anticipating implementing Voice over IP in their network, those that are in the process of piloting Voice over IP or even those that are in the midst of a VoIP implementation would benefit from this title.
The book is best suited for Project Managers, management, telecommunication and Data networking personnel. Really and truly, most anyone would benefit from reading this title. It covers such a broad range of information that having a well educated project team is going to ensure that the project goes smoothly and all things are considered. This book does an excellent job of presenting all of the issues that personnel involved in a Voice over IP project should be aware of to ensure success. It gives the reader a great appreciation for the complexities and helps a great deal with ironing out a good sound strategy.
This book has several figures, tables and diagrams. Like the old saying goes, "A picture is worth a thousand words". This statement holds true in the title. Like I always say, pictures are good.
The book covers everything you'd think about and everything you wouldn't think about.
Coming from the data side of a VoIP solution, I thought I had enough figured out to make a VoIP project a success. This titled made me think about issues that I would have otherwise over looked. Especially issues relating to traditional telecommunications.
Don't start you project without this book. It may end up costing you more than this book in mistakes if you don't.

5-0 out of 5 stars VoIP Simplified
Excellent book if you are looking for "in-depth" crash course in to VoIP. The amazing part was vendor neutral tone. Even though it came out of Cisco Press, it hardly preached any specific vendor. It was mostly focused on the fundamentals.

However the book lacks a decent index section. Hardly any important words are mentioned.

5-0 out of 5 stars A Must Read for any IT Decision Maker
As one of the lead Network / IP Telephony engineers for my employer, GE IT Solutions, I was excited to learn that Cisco Press had published a book addressing the business and project management aspects of Voice Over IP (VOIP). I was glad that I picked up "Taking Charge of Your VoIP Project" by John Walker and Jeffrey Hicks (ISBN 1587200929) and I highly recommend the book to any IT decision maker, project manager, or lead engineer considering VoIP technologies.

The authors clearly indicate in their preface that the book is not a technical "how-to" manual for VoIP. Rather, the target audience is "chief information officers and information technology managers who choose to deploy VoIP in their organizations". The book opens with an overview of VoIP terminology and acronyms. For the most part, the discussion remains at a high level, although the details on IP packet headers probably could've been scaled back, given the target audience. Chapter 2 delves into the business drivers for moving to VoIP, such as convergence and ROI.

Chapter 3, Planning for VoIP, was a particularly helpful section in relation to my job functions. The chapter does a excellent job discussing the value and importance of planning and design for VoIP networks, a critical piece of any VoIP project that I feel customers (and even some vendors and implementers) often overlook. In fact, if it weren't a copyright violation, I'd probably copy the entire chapter and hand it out to any of my existing and potential VoIP customers. Better still, I'll by them a copy of this book.

Subsequent chapters of the book's focus continue to balance the business considerations with the technical aspects of VoIP. Topics of discussion include finding the right implementer, QoS tuning, ongoing VoIP Management, SLAs, and security considerations.

As mentioned earlier, I highly recommend the book to any IT decision maker, project manager, or lead engineer. I've encouraged many of my non-technical business colleagues at GE ITS to read "Taking Charge of Your VoIP Project". In fact, one of our Six Sigma quality leaders engrossed herself in the book and gained an very comprehensive understanding of both the business and technical aspects of VoIP. Next thing I know, she'll be pursuing her CCIE!

5-0 out of 5 stars Taking Charege Of Your Voip Project
I currently work at a Global communications company that is on the cutting edge of worldwide VoIP communications. We are a VoIP provider to several of the Fortune 1000 company's. I am a Data Network Administrator with a background in in voice communications. I also assist in the Internal VoIP projects for the 6 sites I am in charge of. Having said this I have to say that this is one of the best technical reference books I have read concerning the components and software involved in VoIP.

John Walker and Jeffery Hicks more than provide entry-level information regarding several very important aspects of VoIP Implementation. It is easy to see that both have a great deal of knowledge not only regarding VoIP but communications in general.
It was very refreshing to see that two data guys would know so much about voice and the PSTN. I found that the majority of recommended/more information references that are listed at the end of the chapters are either on my desk or on my wish list. This is an excellent bridge for both data and voice technicians.

This book is divided into eight extremely easy to follow well-organized chapters that are written in plain language. While I have read a lot of other technical manuals out of necessity I admit this one I read out of a desire to learn more. This book did not feel like a technical manual. While technical aspects are very well covered this book is less dry than most I have read.

Chapter One Voice basics is a great introduction to either the Data or Telephony networking communities. Regardless of which community you come from you will be engaged. This was a great easy way to start this book. The concepts are built upon from here.

Chapter Two Building a Business Case for VoIP does a fantastic job of outlining the advantages and disadvantages to deploying VoIP. This chapter also covers ROI and other business obstacles that may effect your deployment. I have never personally had to fiure an ROI so I was not informed as to everything involved with processing the information and this book defiantly helped me in that aspect.

Chapter Three Planning for VoIP excellent outline of what needs to be considered before implementation is almost a checklist of what you need to consider and what research needs to be done to your network before you begin.

Chapter Four Do It Yourself, or Outsource is a little more business oriented than other chapters but if you are the decision maker this is an excellent source of questions you need to ask yourself or the provider you chose.

Chapter Five Quality of Service and Tuning is a great introduction to several key concepts. Several important protocols and queueing techniques are covered with enough detail to get you more involved in performance tuning of your network. This book does an excellent job of introducing MPLS and RSVP. This is a great primer and will lead to a desire to read additional books on these concepts as well as the RFCs listed.

Chapter Six Ongoing VoIP Management highlights several tasks that you might want to ensure that your staff can perform/be trained to perform during and after the deployment project. This chapter has several key performance measuring concepts that must be considered. This is one of the more technical chapters but maintains a decent level readability.

Chapter Seven Establishing VoIP SLAs is a step-by-step approach to establishing service levels. The metrics involved in service levels are covered in detail after reading this you will be able to negotiate with your provider or will be able to defend your networks reliability as we all know it is always the network is to slow.

Chapter Eight VoIP Security is veritable list of security concerns as well as concepts for tightening a VoIP network. These techniques are not completely new and can to a certain extent be applied to your data network. Even if you are not currently considering VoIP this is a must read.

All in all this is an excellent book. This is a fantastically written primer to VoIP deployment as well as just an excellent learning tool. I would recommend this book to anyone working in either Telephony or Data networking as converged networks are

5-0 out of 5 stars Must have if you are moving to VoIP
Switching from a PBX system to VoIP involves numerous planning and implementation decisions, both business and technical. There are many new concepts you have to understand well enough to make the right trade-offs. This book is great for stepping you through all the issues, in order, and gives a clear understanding of how the technology really works. Easier to read cover to cover than most technical books. Well written! The authors clearly know their stuff. ... Read more

Book Description

Public radio stands as a valued national institution, one whose fans and listeners actively support it with their time and their money. In this new history of this important aspect of American culture, author Jack W. Mitchell looks at the dreams that inspired those who created it, the all-too- human realities that grew out of those dreams, and the criticism they incurred from both sides of the political spectrum. As National Public Radio's very first employee, and the first producer of its legendary "All Things Considered," Mitchell tells the story of public radio from the point of view of an insider, a participant, and a thoughtful observer. He traces its origins in the progressive movement of the 20th century, and analyzes the people, institutions, ideas, political forces, and economic realities that helped it evolve into what we know as public radio today. NPR and its local affiliates have earned their reputation for thoughtful commentary and excellent journalism, and their work is especially notable in light of the unique struggles they have faced over the decades. This comprehensive overview of their mission will fascinate listeners whose enjoyment and support of public radio has made it possible, and made it great. ... Read more

4-0 out of 5 stars For public radio insiders and those who wished they were.
If you're a public radio fan wanting to know what Garrison Keillor is really like, or how angry Bob Edwards actually got when he exited Morning Edition unwillingly after almost 25 years as host, this is not the book for you. It is a highly readable, highly personal perspective on the philosophies and politics that shaped NPR and made public radio a force in American media. Those most apt to appreciate it are among the thousands of people who have been employed in public radio over the last 30 years -- including career veterans who will recognize the names and remember the events that Mitchell recalls, but will undoubtedly have their own, differing passionate points of view. As a minor, second or third row witness to about 20 years of this history, much of what Mitchell writes seems surprisingly accurate and objective, although rather Mitchell-centric -- but the author warns the reader to expect that in the first few pages. ...

4-0 out of 5 stars a good book
If you are familiar with statistical signal processing, this book can be stepping stones to adaptive signal processing. A brief introduction of statistical signal processing is contained in this book but detailed knowledges on DSP and probability & random process are required. Find books by Hayes, Widrow and Haykin if you are interested in statistical signal processing and adaptive signal processing. ... Read more

Book Description

Naturalness in synthetic speech is one of the most intractable problems in information technology today. Although speech synthesis systems have improved considerably over the last 20 years, they rarely sound entirely like human speakers.

Why is this so, and what can be done about it?

  • Prosodic processing must be rendered more varied and more appropriate to the speech situation

  • Timing, melodic control and the relationships between the various prosodic parameters need increased attention

  • Signal processing systems must be developed and perfected that are capable of generating more than just one voice from a database

  • A better understanding must be achieved of what distinguishes one voice from another, and of how speech styles differ between simply reading aloud numbers and sentences and their use in interactive speech

  • New evaluation methodologies should be developed to provide objective and subjective measurements of the intelligibility of the synthetic speech and the cognitive load imposed upon the listener by impoverished stimuli

  • Adequate text markup systems must be proposed and tested with multiple languages in real-world situations

  • Further research is required to integrate speech synthesis systems into larger natural-language processing systems
Improvements in Speech Synthesis presents the latest research in the above areas. Contributors include speech synthesis specialists from 16 countries, with experience in the development of systems for 12 European languages. This volume emerges from a four-year European COST project focussed on "The Naturalness of Synthetic Speech", and will be a valuable text for everyone involved in speech synthesis. ... Read more
