7720AE4-HD HDTV 4 Channel AES Audio Embedder
Revision 1.1 7720AE4-HD-1
1. OVERVIEW
The 7720AE4-HD Audio Embedder inserts AES audio signals into a 270 Mb/s SDI video signal as
specified in SMPTE 299M. The companion 7720AD4 Audio Deembedder facilitates audio demultiplexing
at the destination.
SMPTE 299M allocates four groups of four audio channels that can be embedded into the SMPTE 292M
bitstream. The 7720AE4-HD embeds up to 4 AES audio into two selectable groups on the SDI outputs for
discrete 5.1 audio applications. The 7720AE4-HD 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 video input format
•Bypass relay protection on one HD SDI output for power failures
•24-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-HD 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: 7720AE4-HD Rear Panels
SDI INPUT Input BNC connector for 10-bit serial digital video signals compatible with the SMPTE 292M
standard.
SDI OUTPUT There are two BNC connectors with reclocked serial component video outputs, compatible
with the SMPTE 292M standard. These outputs contain the input video with the audio present
at AES inputs 1 to 4 embedded in accordance with the SMPTE 299M standard. On the
7720AE4-HD 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.

4. STATUS LEDS
The location of the status LEDs is shown in Figure 3.
4.1. MODULE STATUS LEDS
MODULE OK This Green LED will be On when the module is operating properly. Depending on
the Status LED mode chosen, the LED will be on solid when input video, or audio
or both video and audio is present (see section 5.6)
LOCAL FAULT This Red LED makes it easy to identify one module in a frame that is missing an
essential input or has another fault.
The LED will blink on and off if the microprocessor is not running.
Depending on the Status LED mode chosen, the LED will be on solid when input
video, or audio is missing from all AES inputs, or both video and audio are missing.
In addition this Led will be on when there is a fault in the module power supply.
VIDEO PRESENT This Green LED will be On when there is a valid video signal present at the module
input.
AUDIO PRESENT This Green LED will be On solid when there is a valid AES audio signal present at
any of the AES inputs. In Locked Group mode, the LED will be on when there is at
least one input on the AES 1 or AES2 and AES 3 or AES 4 inputs.
ERROR: This Yellow LED will be On when there are errors in the embedding process (E.g.
FIFO underflow)
4.2. AUDIO GROUP AND MODE STATUS LEDS
Four LEDs located on the lower end of the module (opposite the DIP switch) indicate the status of the
audio groups when the DIP switches are all set to the OFF condition. LED 1 is located closest to the
center of the module. When the DIP switches are set to other values, these LEDS are used to indicate
various operational modes of the module. (See Table 1).
