Note) Closed Caption Extended Data is written in order of 0x28 and then 0x29.
When the second byte (0x29) of Closed Caption Extended Data is written, the AK8826 interprets that Data has been up-dated
and it encodes the Data on the next Video Line.
Null Codes are automatically output on those, not-data-updated lines.
It is assumed that Parity bit of each Byte Data is added by the Host side.
