I don't have a good primer to recommend. I have found the how it works
sites to be useful. Here is one for the DVD.

http://electronics.howstuffworks.com/dvd1.htm

Video is no longer stored in analog form. The old laser disk was just a
digital copy of the analog information, with no real compression. The DVD
on the other hand is a compressed form of storage. The term codec is for
encoder and decoder. Your DVD player is just a MPEG2 decoder. MPEG2 is the
most common video compression method. Direct TV, DVD, use it to deliver
video content in a form that takes up less space than the raw analog form.
(less space on the disk or a smaller part of the satellite link for each
channel.) As others have stated, h.264 is just another encoding method. It
is the new kid so to speed. It takes a powerful computer to reconstruct the
picture that you see on the TV. Its primary advantages are:

1. Reduced file size.
2. Improved video quality over all forms of MPEG2. i.e. fewer artifacts in
the picture, more even transitions form block to block. (You see this as
blocking on dark areas of a DVD.)

Its primary drawbacks are:

1. CPU intensive to encode and decode.
2. Unsupported in many current devices.

Hope this helps,
