2.7.2 VBI Raw Data Output
The TVP5147M1 decoder can output raw A/D video data at twice the sampling rate for external VBI slicing.
This is transmitted as an ancillary data block, although somewhat differently from the way the sliced VBI data
is transmitted in the FIFO format as described in Section 2.7.1. The samples are transmitted during the active
portion of the line. VBI raw data uses ITU-R BT.656 format having only luma data. The chroma samples are
replaced by luma samples. The TVP5147M1 decoder inserts a four-byte preamble 000h 3FFh 3FFh 180h
before data start. There are no checksum bytes and fill bytes in this mode.

Reset and Initialization
Reset is initiated at power up or any time terminal 34 (RESETB) is brought low. Table 29 describes the status
of the TVP5147M1 terminals during and immediately after reset.
