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