1 Introduction
The TVP5031 is a high quality single-chip digital video decoder that converts base-band analog National Television
System Committee (NTSC) and phase alternating line (PAL) video into digital component video. The TVP5031
includes a 9-bit A/D converter with 2x sampling. Sampling is square-pixel or ITU-R BT.601 (27 MHz) and is line-locked
for correct pixel alignment. The output formats can be 8-bit, 10-bit or 16-bit 4:2:2, and 8-bit or 10-bit ITU-R BT.656
with embedded synchronization. The TVP5031 utilizes Texas Instruments patented technology for locking to weak,
noisy, or unstable signals, and a chroma frequency control output is generated for synchronizing downstream video
encoders.
Complementary three-line adaptive (2-H delay) comb filtering is available for both the luma and chroma data paths
to reduce both cross-luma and cross-chroma artifacts; a chroma trap filter is also available. Video characteristics
including hue, contrast, and saturation may be programmed using one of four supported host port interfaces; I
2
C and
three parallel host interface (PHI) modes. The TVP5031 generates synchronization, blanking, field, lock and clock
signals in addition to digital video outputs.
The TVP5031 includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI data processor
slices, parses, and performs error checking on teletext data in several formats. A built-in FIFO stores up to 14 lines
of teletext data, and with proper host synchronization full-screen teletext retrieval is enabled. The VBI data processor
also retrieves closed-caption data. The TVP5031 can also pass through over sampled raw composite data for
host-based software VBI processing.
The main blocks of the TVP5031 include:
Analog processors and A/D converters
Y/C separation
Chrominance processor
Luminance processor
Clock/timing processor and power-down control
Output formatter
Host port interface
VBI data processor
