Don is right and you may have to look to different sources depending on the specific information desired. I find that video tends to fall into three general categories: production/recording, broadcast/transmission and display (projection, screens, flat panels, etc.). Streaming/compression and related technologies could be a newer fourth area and where it applies film is probably even yet another area. Many people work in one, two or even three of these areas but few work in all of them, so you often find that the related texts and information also tend to fall into these loose categories. So if you want to know the amount of data recording an hour of MPEG-4 video takes you would likely find that information in a very different place than how to calculate screen size which would probably be different than where you might find how to calculate signal loss in a coax cable and so on.
For the AV world, Extron and Da-Lite both have some excellent resources available online. You might also look at "The Basics of Audio and Visual Systems Design" book that InfoComm offers that gathers together information from a number of other resources.
