Revision 1.2 Page-1
1. OVERVIEW
The 7720AE4 Audio Embedder inserts AES audio signals into a 270 Mb/s SDI video signal as specified in
SMPTE 272M. The companion 7720AD4 Audio Deembedder facilitates audio demultiplexing at the
destination.
SMPTE 272M allocates four groups of four audio channels that can be embedded into the SMPTE 259M
bitstream. The 7720AE4 embeds up to 4 AES audio into two selectable groups on the SDI outputs for
discrete 5.1 audio applications. The 7720AE4 is Dolby E compliant when the sample rate converters are
turned off.
VistaLINK®enables control and configuration capabilities via Simple Network Management Protocol (SNMP). This
offers the flexibility to manage the module status monitoring and configuration from SNMP enabled control systems
such as Evertz VistaLINK®Pro locally or remotely.
Features:
•Automatic detection of 525 line and 625 line input
•Bypass relay protection on one SDI output for power failures
•20-bit AES input and audio embedding
•Individual audio group assignment for each group
•Group lock mode maintains phase relationship between the groups for 5.1 audio applications
•Sample rate conversion disable on AES inputs to permit Dolby E embedding
•Programmable audio delays (up to 7 frames in ½ video field resolution) using DIP switches
•Ancillary packet cleaning mode removes all audio before embedding
•Ancillary packet reformatting mode left justifies and removes unused packets before
embedding
•Embeds audio on internally generated black or blue video when there is no video input
•VistaLINK®control capabilities for module configuration. VistaLINK®capabilities are available
when modules are used with the 3RU 7700FR-c frame and a 7700FC VistaLINK®Frame Controller
module in slot 1 of the frame. (feature not implemented at this time)
•Front panel LEDs indicate video and audio signal presence, and module fault

2. INSTALLATION
The 7720AE4 modules each come with a companion rear plate that has 7 BNC connectors. For
information on mounting the rear plate and inserting the module into the frame see section 3 of the
7700FR chapter.
Figure 2-1: 7720AE4 Rear Panels
SDI INPUT: Input BNC connector for 10-bit serial digital video signals compatible with the
SMPTE 259M standard.
SDI OUTPUT: There are two BNC connectors with reclocked serial component video outputs,
compatible with the SMPTE 259M standard. These outputs contain the input video
with the audio present at AES inputs 1 to 4 embedded in accordance with the
SMPTE 272M standard. On the 7720AE4 the top SDI output is protected by a
bypass relay, which will activate in the event of power loss to the module. The
remaining output is not bypass protected.
AES INPUT 1: AES audio input for channel 1 and 2 of the audio group selected for embedding by
embedder 1.

AES INPUT 2: AES audio input for channel 3 and 4 of the audio group selected for embedding by
embedder 1.
AES INPUT 3: AES audio input for channel 1 and 2 of the audio group selected for embedding by
embedder 2.
AES INPUT 4: AES audio input for channel 3 and 4 of the audio group selected for embedding by
embedder 2.
