Video DemysTIfied A Handbook for the Digital Engineer Fourth EdiTIon by Keith Jack

A few short years ago, the applicaTIons for

video were somewhat confined—analog was

used for broadcast and cable television, VCRs,

set-top boxes, televisions and camcorders.

Since then, there has been a tremendous and

rapid conversion to digital video, mostly based

on the MPEG-2 video compression standard.

Today, in addiTIon to the legacy DV,

MPEG-1 and MPEG-2 audio and video compression

standards, there are three new highperformance

video compression standards.

These new video codecs offer much higher

video compression for a given level of video

quality.
