7721AD8‑HD & 7721AD8‑B‑HD

HD/SD-SDI 4 Group Audio De-Embedder

Product Manual Manual
VistaLINK® enabled Dolby Partner

The 7721AD8-HD Audio De-embedder extracts embedded audio from all 4 groups of a 1.5Gb/s serial HD or a 270Mb/s serial SD video signal as specified by SMPTE ST 299 or ST 272 respectively. The module supports 24-bit AES audio de-embedding for HD and 20-bit audio de-embedding for SD. Up to 16 selected channels may be de-embedded and directed to 8 AES outputs. In addition, a full 16x16 audio channel router is available for channel re-mapping.

The 7721AD8-HD is Dolby E® compliant and handles Dolby E® Metadata. Metadata is optionally de-embedded from VANC and can be provided as an output for downstream devices like Dolby E® or Dolby AC3® Encoders.

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.

Features
  • Audio de-embedding from 1.5 Gbs HD or 270 Mbs SD video
  • Automatic detection of input video standard
  • Two 1.5 Gbs HD or 270 Mbs SD serial video outputs
  • Supports 24-bit AES audio de-embedding for HD and 20-bit AES audio de-embedding for SD
  • Flexible 16x16 audio channel routing for channel re-mapping
  • Dolby E® compliant with VANC decode and output of Dolby™ metadata
  • Card edge display for status and miniature bargraphs for audio peak levels
  • 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 7700FC VistaLINK® Frame Controller module in slot 1 of the frame
