Query: It's very good for understanding the components.

I enjoyed this book very much. It's strength is in all the detailed information on the components that make up your system. It is very thorough (almost too much so) about all the various video delivery and sound decoding systems and equipment choices available to you the consumer. It has very little information about how to actually install the equipment in your home. It does not tell you how to run the cables and hide the wires, but that's is covered very well in other books.I believe it would be an excellent resource for both the hobbiest and the professional. Note: in this field it is necessary to update the material almost constantly. My edition, even though only a year old, was out of date in a few areas. Bottom line, make sure you buy the latest edition.
