AVS6800+B2D, +C2D

Audio Delay and Video Frame Synchronizer

The AVS6800+B2D and AVS6800+C2D modules for the 6800+™ core processing platform are used to synchronize AES audio signals with an associated video signal. DARS and genlock reference inputs provide for AES11 compliance. AES input and output ports provide full 24-bit capability, and enable the passing of compressed audio streams. Modules accept a single SD-SDI input and provide two AES audio paths in either balanced (+B2) or unbalanced (+C2) formats. These modules can be used in combination with other 6800+ modules to provide added video and audio capabilities such as audio tracking delay and hot-switching.

The AVS6800+ modules can be controlled manually via card-edge controls, or controlled and monitored via the CCS Navigator™ software application, HTTP web browser, NUCLEUS™ hardware control panels or third-party SNMP-based control applications.

Features

  • Input standard 525/625 operation auto-detect or user-forced
  • EDH reinsertion
  • Audio re-sampling for 32 to 108 kHz AES outputs, with bypass for data over AES operation
  • C, U and V bit transparency
  • Full-featured, 10-bit serial 4:2:2 frame synchronizer
  • Two processed and one reclocked outputs
  • Removes low frequency jitter from 270 Mb/s video
  • Passes all ancillary data including embedded audio, VBI (HANC and VANC)
  • GPI freeze control
  • One frame delay buffer
  • Delay or synchronizer modes
  • Frame-store tracking and system delay operation
  • Genlock reference input (internal and external)
  • Variable delay operation (1.2 seconds)
  • Audio monitoring output
  • Minimum tracking delay of 1.3 seconds
  • AES input and output provide full 24-bit capability
  • Supports card-edge and remote control of module (via CCS Navigator, web browser and third-party SNMP-based control applications)
