InfoFrame data byte
Description
audio InfoFrame packet type:
gives the packet type of the audio
InfoFrame packet (80h +
InfoFrame type code as per
EIA/CEA-861B )
audio InfoFrame version: gives
the version number of the audio
InfoFrame
reserved (shall be zero)
audio InfoFrame length: gives
the number of data bytes for the
audio InfoFrame; this length does
not include the checksum
audio 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 audio InfoFrame
packet contents (determined by
InfoFrame length) plus the
checksum itself equals 0
