The 7721DD4-HD Quad Serial Data De-embedder extracts 4 x RS-232 or RS-422 serial data streams and GPI contact closure information from a 270Mb/s SD-SDI or 1.5Gb/s HD-SDI video signal. A data error detection and correction scheme is also applied to maintain data integrity on the output of the data de-embedder. At the embedded packet layer, data packets resemble and have the same group DIDs as embedded audio packets. The data is un-packetized and extracted from the AES sub-frame according to SMPTE ST 337. Adding the +GPI option to the decoder (model 7721DD4-HD+GPI) allows the user to decode remote control contact closure information from VITC (SD) or SMPTE ST 12-2 ATC (HD) user bits instead of decoding the GPI information from the AES embedded data stream. This feature allows the user to use remote control user bit patterns to control the six GPO relay outputs. At the encoder end the 7721DE4-HD+GPI GPI Encoder module encodes the remote control user bits in VITC or SMPTE ST 12-2 ATC. The 7721DD4-HD module occupies one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
  • Automatic detection of SD-SDI or HD-SDI video input
  • 4 x RS-232/422 serial outputs with selectable baud rate
  • Parity selection: none, even or odd
  • Support serial input with BREAK character according to SMPTE ST 207
  • Packetize data into sub-frame AES format according to SMPTE ST 337
  • Share the same group DIDs as for embedded audio, selectable from group 1 to 4
  • Group selection for extracting data from one of four Audio Groups
  • Redundant data transmission to allow data error detection and correction at the receiver end
  • Six GPI outputs to embed simple control information into the video input
  • Automatically remove the existing embedded packets when the conflict of group DID occurs
  • Card edge LEDs indicate video signal and data presence, cable equalization and module fault
  • With GPI Option - Decodes GPO relay contact closure information from VITC or ATC user bits (instead of decoding the GPI information from AES data)
