1: Great intermediate intro to subject
This is a very well written book on digital TV for the intermediate student or reader. It steers a middle course between the more technical or professional level TV books, such as the well known Whitaker volume published by McGraw Hill, and the more basic books such as The Dummies guides. For me, it was just right since the more advanced books were a bit too hard for me yet, but the easier books were too basic.
The book is especially strong on the digital compression issues, and the chapter on middleware and operating systems is really exceptional, a subject that often isn't addressed as completely in some other volumes. The second to the last chapter provides a nice summary of the main features and differences between satellite, terrestrial broadcast, and cable digital TV.
It's still a fairly technical book, though, and you should already have some basic knowledge of what digital TV is and how the three main types, which are terrestrial, satellite, and cable-based digital TV, differ from each other. Obviously, there are many similarities, but they differ most in the use of different signal modulation techniques and the nature and extent of the error correction in order to best make use of the available bandwidth.
For example, obviously satellite and broadcast TV are most susceptible to multipath interference and other types of noise, hence the signal to noise ratio of these technologies is lower than cable. Cable has a much better signal (25 to 30 db instead of perhaps 6 db), and yet suffers from internal echoes due to impedance mismatches along the long segments of cable. This implies that broadcast and satellite TV need more robust and extensive error correction, which is true. However, satellite may reach areas too remote for typical cable.
The book also has several chapters dealing with the more technical aspects of compression, error correction, etc., for those who are interested. Overall, an excellent brief book (less than 300 pages), and it's also nicely bound on good quality paper in signatures so that the binding will hold up better over time and the pages won't fall out.
