The 520AD4-DD-HD Audio De-embedder & Dolby Decoder & Re-embedder extracts embedded audio from 2 specified groups as defined by SMPTE 299M from a 1.5Gb/s serial HD or as defined by SMPTE 272M from a 270Mb/s serial SD video signal. One selected channel is processed by the on-card Dolby Decoder. If the channel contains Dolby-E® or Dolby Digital (AC-3)™, it will yield up to 8 additional discrete audio channels and the associated Dolby-E® metadata. Up to 8 selected channels may be optionally delayed up to 3 seconds and re-embedded into the output video and/or directed to 4 AES outputs. Video output may be optionally delayed up to 7 frames to help with lip sync. If PCM audio is embedded, the device acts as a simple 2 group audio de-embedder.

This device also handles the Dolby-E® Metadata. Metadata is optionally embedded in VANC and can be provided as an output for downstream devices (i.e. Dolby-Encoders, Multichannel Audio Tool, etc.). Dolby-E® is capable of carrying LTC data embedded within its stream. It can be selected as an output, instead of metadata.

For lip sync cohesion and ease of editing, Dolby-E® data is organized in blocks with lengths matching the associated video frame. The decoder will match the beginning of each output block with the start of video, as provided with the genlock input. Additional delay can be dialed up by the user, up to 3 seconds. An extra AES input is provided that can be configured as a backup channel, in the event the primary is lost, or as a voice-over source. This input can be re-configured as a metadata input which can be embedded in VANC, instead of the metadata coming from Dolby Decoder.

  • Automatic switchover to backup audio source on loss of selected Dolby stream
  • Adjustable video delay to match Dolby decoder audio delay (up to 7 frames)
  • Secondary AES input with backup, voice-over or Dolby-E/AC-3™ content
  • Card edge display for Dolby decoder status & audio channel peak levels bargraphs
  • VistaLINK® -capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 500FR frame with 500FC VistaLINK® Frame Controller
