Description
Description
MPEG source InfoFrame packet
type: gives the packet type of the
MPEG source InfoFrame packet
(80h + InfoFrame type code as per
EIA/CEA-861B )
MPEG source InfoFrame
version: gives the version number
of the MPEG source InfoFrame
reserved (shall be zero)
MPEG source InfoFrame length:
gives the number of data bytes for
the MPEG source InfoFrame; this
length does not include the
checksum
MPEG source InfoFrame
checksum: shall be calculated
such that a byte-wide sum of all
three bytes of the packet header
and all valid bytes of the MPEG
source InfoFrame packet contents
(determined by InfoFrame length)
plus the checksum itself equals 0
MPEG source InfoFrame MPEG
