BitstreamJPEG (Joint Photographic Experts Group)
This is the digital form of multi-channel audio data (e.g., 5.1 channel)
before it is decoded into its various channels.This is a system used for compressing/decoding color still pictures. If
you select JPEG as the storage system on digital cameras etc., the
CPRM (Content Protection for Recordable Media)data will be compressed to 1/101/100 of its original size. The
