ETABYTES DATA
In program stream and pack stream modes, the SAA6752HS can append additional metabyte data packets to the
stream, providing information on sector information for downstream application processing. The video and audio
metabytes format is defined in Tables 6 and 7. The sector and metabytes form a block format, where each sector of
2048 bytes is followed by 16 metabytes containing data on the previous sector.
