Closed Caption
The TVP6000 can be programmed to encode closed caption data and extended data in the selected line.
The closed caption data are sent to the TVP6000 through the I
2
C interface. The data stream consists of a
seven-bit US-ASCII code and one odd parity bit as shown below.

The standard service encodes closed caption only in the odd field, while the extended service encodes
closed caption in both fields. L21ENA, when set to 1, enables closed caption encoding in the odd field and
L21ENB, when set to 1 enables closed caption encoding in the even field.
The scan line where closed caption is to be encoded is programmable through the SLINE register at
subaddress 6B.
Four closed caption data registers contain the closed caption data to be encoded. Registers LINE21_O0
and LINE21_O1 contain the first byte and the second byte of the close caption data to be encoded in the
odd field. Registers LINE21_E0 and LINE21_E1 contain the first byte and the second byte of the closed
caption data to be encoded in the even field. Immediately after the closed caption data is written to the closed
caption data registers either for the odd field or even field, the corresponding closed caption status bit, CCE
or CCO in the STATUS register at subaddress 02, is reset to 0 to indicate the closed caption data is available
in the closed caption data registers and yet to be encoded. Immediately after the closed caption is encoded,
the CCE or CCO bit is set to 1 to indicate the closed caption data has been encoded and is ready to accept
new data. The null character is automatically inserted if the closed caption data is not written to the closed
caption data registers in time for encoding.
The run-in clock frequency is 503496.5 Hz ( 32
×
fline of NTSC ). The closed caption data is encoded in the
format of non-return to zero (NRZ). Additionally, the data translates to the IRE scale in the following manner:
0= 0 IRE; 1 = 50 IRE.
