ADV7181B:  NTSC/PAL/SECAM Video Decoder

Product Description

The ADV7181B, part of ADI's new generation of integrated video decoders automatically detects and converts a standard analog baseband television signal compatible with worldwide standards NTSC, PAL, or SECAM into 8-bit precision 4:2:2 component video data.

Updates in the B revision include improved performance for noisy or weak signal inputs, better VCR locking capability and various decoder core enhancements. An interrupt request output pin is also added to flag real-time events to the host system.

ADI's ADLLT (Adaptive Digital Line Length Tracking) technology brings advantages to any digital video capture, processing or display application. A proprietary architecture for variable input video quality detection and synchronisation, ADLLT enables:

  • Stable TV Tuner Signal Capture
  • Reliable VCR Signal Capture
  • Non-Standard Video Signal Capture
  • Automatic Source-Dependent Y/C seperation

Applications

  • Low-Cost Consumer Video Capture Devices
  • DVD recorders
  • Video Projectors
  • HDD-based PVRs/DVDRs
  • LCDTVs
  • Set-Top Boxes
  • PC Video Editing
  • Industrial Video Capture

Features

  • Performance upgrade from ADV7181
  • Improved sync proccessing for TV & VCR Inputs
  • Interrupt Request Output
