7821AE8-3G, 7821AE8-3G-AESD, 7821AE8-B-3G, 7821AE8-LTC-3G
3G/HD/SD-SDI 8 AES Audio Embedder with Dolby® Metadata Inserter
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 (1.5 Gb/s HD-SDI) or
SMPTE 259M (270Mb/s SD-SDI) video signal as specifi ed 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.
Features & Benefi ts
• 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 shuffl ing 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-B3G)

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 confi guration capabilities via Simple Network
Management Protocol (SNMP). This offers the fl exibility to manage the module
status monitoring and confi guration locally or remotely.
• 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 confi guration
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
