What does

The standards for the compact disk were defined by Sony/Philips and published in a book that was (literally) red. At least that's what I think it means. It's used now to differentiate "regular" cds from sacd's and dvd-a's.

Redbook is the standard CD. Sony literaly had (has) a red book with all the specs for CD code back when they were first developed. There have been other threads you could look up if you want more info.

16 bit, 44.1kHz Compact disc standard.

The CD standard was originally developed by Mao Tse Tong.
It was given to Nixon by Mao himself during his visit to China in 1972 as part of a cultural exchange that involved some ping pong tables and an alpaca.

I don't even want to think about what Nixon did with the Alpaca.
