This makes it really difficult for me - and especially since we are gaining new members everyday, I was wondering if we could flesh out the glossary with easily digestible, but thorough definitions and explanations. (running them through mods or admin first, of course.

suggestions:
What does PCM mean, what does it do
What is Bitstream, what does it do
List each sound format and list it's capability for bitrates/lossless audio
What does lossless mean
what's a bitrate and why is it important
what is each type of cable connection capable of carrying for audio/video
what is pulldown in video, why is it done
If set my player to PCM, what sound formats can be transmitted properly
If set my player to bitstream, what sound formats can be transmitted properly

We've got a Glossary on the home page, it would be easy to point people to solid, agreed upon answers in the glossary. Personally, it would make learning about this new world of hi-def media much easier.

Anybody up to it???

Cheers,

Doc

I don't swear by it, but I recommend Wikipedia for stuff like this. Even though you can't be sure that EVERYTHING is true but you will get the idea of what it means...for example:

What does PCM mean, what does it do
