The TVP5151 decoder utilizes Texas Instruments patented technology for locking to weak, noisy, or

unstable signals. A Genlock/real-time control (RTC) output is generated for synchronizing downstream

video encoders.

Complementary four-line adaptive comb filtering is available for both the luminance and chrominance data

paths to reduce both cross-luminance and cross-chrominance artifacts; a chrominance trap filter is also

available.

Video characteristics including hue, brightness, saturation, and sharpness may be programmed using the

industry standard I

C serial interface. The TVP5151 decoder generates synchronization, blanking, lock,

and clock signals in addition to digital video outputs. The TVP5151 decoder 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 TVP5151 decoder detects copy-protected input signals according to the Macrovision™ standard and

detects Type 1, 2, 3, and colorstripe processes.

The main blocks of the TVP5151 decoder include:

• Robust sync detector

• ADC with analog processor

• Y/C separation using four-line adaptive comb filter

• Chrominance processor

• Luminance processor

• Video clock/timing processor and power-down control

• Output formatter

• I

C interface

• VBI data processor

• Macrovision detection for composite and S-video
