For sale is ONE (1) used 520AD4-HD board in very good condition. Card fits 500FR (not included). Because we have a quantity of these, appearances may vary, but condition is guaranteed to be better or equal to pictured sample. Serial numbers are unique to each unit sold and may be different from one depicted in the photos - we record all serial numbers of all items shipped
The 520AD4-HD Audio De-embedder extracts embedded audio from 2 specified groups as defined by SMPTE ST 299-1 from a 1.5Gb/s serial HDTV or as defined by SMPTE ST 272 from a 270Mb/s serial SD video signal.
Up to 8 selected channels may be delayed up to 3 seconds and re-embedded onto the output video and/or directed to 4 AES outputs. An extra AES input is provided as a backup channel, in case of loss of primary, or as the source of voice-over. The video output may be optionally delayed up to 5 frames to achieve lip sync with the audio.
This device also handles the Dolby® E Metadata in VANC. The module has multiple sources for this metadata including VANC, and externally supplied metadata. The decoded or de-embedded Dolby® E metadata can be provided as an output for downstream devices (ie. Dolby® E encoders etc.).
