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 2-9 describes the
status of the TVP5147M1 terminals during and immediately after reset.
