Introduction
The TVP5150 is a highly integrated low-power video processor, with full video decoding functionality and
scaling and audio support. The optimized architecture of the TVP5150 allows for low power consumption.
The high quality single-chip digital video decoder on the TVP5150 converts base-band analog NTSC, PAL,
and SECAM video into digital YUV 4:2:2 component video. Y/C composite and S-video inputs are also
supported. Digital inputs are supported for YUV 4:2:2, which can then be digitally processed for output on the
output YUV databus. The TVP5150 includes one 9-bit A/D converters 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 4:2:2 or 8-bit ITU-R BT.656 with embedded syncs.
The TVP5150 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 or four-line adaptive 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.
The TVP5150 allows scaling of the input image to various other formats. The scaling can be done in the
horizontal and vertical directions. A windowing (cropping) function allows zooming into any desired area in
the captured image.
Video characteristics including hue, contrast, and saturation may be programmed using the I2C high-speed
bus interface. The TVP5150 generates synchronization, blanking, field, lock, and clock signals in addition to
digital video outputs. The TVP5150 includes methods for advanced vertical blanking interval (VBI) data
retrieval. The VBI data processor slices, parses, and performs error checking on Teletext, closed caption, and
other data in several formats.
The device has an internal ROM to execute programs.
The TVP5150 detects copy protected input signals according to Macrovision standard.
The main blocks of the TVP5150 include:
A/D converter with analog processor
Y/C separation
