auxiliary video information InfoFrame
packet type: gives the packet type of the
auxiliary video information InfoFrame
packet (80h + InfoFrame type code as
per EIA/CEA-861B )
auxiliary video information InfoFrame
version: gives the version number of the
auxiliary video information InfoFrame
reserved (shall be 000)
auxiliary video information InfoFrame
length: gives the number of data bytes
for the auxiliary video information
InfoFrame; this length does not include
the checksum
auxiliary video information 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
auxiliary video information InfoFrame
packet contents (determined by
InfoFrame length) plus the checksum
itself equals 0
