Closed Caption Data 1 Register (R/W) [Address 0x26]
Closed Caption Data 2 Register (R/W) [Address 0x27]
Register to set Closed Caption Data ( SD ). It is also possible to output same data on HD side.
Sub Address 0x26 < SD Block >
Sub Address 0x27 < SD Block >
note ) Closed Caption Data is written in order of 0x26 and then 0x27.
When the second byte ( 0x27 ) of Closed Caption Data is written, the AK8823 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.
Closed Caption Extended Data 1 Register (R/W) [Address 0x28]
Closed Caption Extended Data 2 Register (R/W) [Address 0x29]
Register to set Closed Caption Extended Data ( SD ). It is also possible to output same data on HD side.
Sub Address 0x28 < SD Block >
Sub Address 0x29 < SD Block >
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 AK8823 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.
