3G/HD/SD-SDI 8 AES Audio Embedder with Dolby® Metadata Inserter

Interact with this product in a Layout Tool:

The 7821AE8-3G Audio Embedder inserts up to 8 AES audio signals, on up to 4 groups, into a SMPTE 424M (3Gb/s), ST 292-1 (1.5Gb/s HD-SDI) or SMPTE 259M (270Mb/s SD-SDI) video signal as specified in ST 299-1 or 272M respectively. The companion 7821AD8-3G Audio De-embedder facilitates audio demultiplexing at the destination.

The 7821AE8-3G supports 24-bit AES audio embedding for 3G/HD-SDI and 20-bit audio embedding into SD-SDI with fully compliant sample rate converters that automatically can be disabled when embedding Dolby streams.

Additionally, a full 16x16 audio channel router is available for channel mixing and/or shuffling. With the -AESD suffix applied (7821AE8-3G-AESD), the rear plate comes equipped with DIN connectors for direct AES connections, eliminating the use of a breakout cable. The 7821AE8-LTC-3G will embed Linear Time Code (LTC) as Ancillary Time Code (ATC) in 3Gbs/HD and DVITC in SD.

VistaLINK® enables control and configuration capabilities via Simple Network Management Protocol (SNMP). This offers the flexibility to manage the module status monitoring and configuration locally or remotely.

特点|

  • Audio embedding into a 3G/HD/SD-SDI video signal
  • Automatic detection of input video standard
  • Four serial video outputs (same standard as input)
  • By-pass relay protection for main program output
  • Supports 24-bit AES audio embedding for 3G/HD-SDI and 20-bit AES audio embedding for SD-SDI
  • Flexible 16x16 audio channel routing for channel shuffling and mixing
  • Dolby compliant with automatic sample rate conversion disable on AES inputs to permit seamless Dolby embedding
  • Dolby® Metadata insertion via serial interface (not available on 7821AE8-B-3G)
  • LTC embedding (7821AE8-LTC-3G only)
  • Card edge LEDs indicate video and audio signal presence and module fault
  • VistaLINK® capable for remote monitoring, control and configuration capabilities via SNMP; using VistaLINK® PRO, CP-2116E or CP-2232E Control Panels. VistaLINK® is available when modules are used with the 3RU 7800FR frame and a 7800FC VistaLINK® Frame Controller module in slot 1 of the frame
