Revision 1.4.3 7721DD-1
1. OVERVIEW
The 7721DD SDI data deembedder extracts data that has been embedded into a 270 Mb/s SDI video
signal by the 7721DE data embedder and outputs it as an RS 232/422 data stream and GPO contact
closures. The data packets are first deembedded from the SDI video then deformatted from AES audio
packets into the original data stream. A data error detection and correction scheme is also applied to
maintain data integrity. At the embedded packet layer, data packets resemble and have the same group
DIDs as embedded audio packets.
Features:
•Automatic detection of 525 and 625 line SDI video input
•Automatic activation of internal 525 or 625 line black video generation at the loss of video input
•Deembedding mechanism based on SMPTE 272M-A
•Share the same group DIDs as for embedded audio, selectable from group 1 to 4
•Channel selection for extracting packetized data from one of four channels within a data group
•Deformats AES audio (sub-frame mode) to generic data content according to SMPTE 337M
•Supports data error detection and correction, or minimum delay mode without correction
•One RS232/422 serial output with automatic baud rate at 9600, 14,400, 19,200, 38,400 or 57,600
•Support serial output with regenerated parity matched to the upstream input
•Support serial output with regenerated BREAK character according to SMPTE 207M
•Six TTL level GPO signals activate when corresponding GPI inputs on 7721DE are activated.
•Clean or pass-through packets after de-embedding
•Removes packets with "Marked packets for deletion" and "Data end marker packet"
•EDH generation on video output
•Card edge LEDs indicate video signal and data presence, cable equalization and module fault.

2. INSTALLATION
The 7721DD modules each come with a companion rear plate that has 3 BNCs and a high-density female
DB 15 connector. For information on mounting the rear plate and inserting the module into the frame see
section 3 of the 7700FR chapter.
Figure 2: 7721DD Rear Panel
2.1. VIDEO INPUTS AND OUTPUTS
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 a reclocked copy of the input video.
The top 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.

The GPOs are activated when the corresponding GPI inputs on the 7721DE Data Embedder are
avtivated. They can be used to pass simple contact closure information along with the video signal. The
GPOs are active low with an internal pull up (10k Ohm) resistor to the Vext pin. When active, the output
will go low and is able to sink up to 10mA. When inactive, the signal will go high (to the voltage applied to
the Vext pin). Do not attempt to source more than 100µA from the output.

The user can connect GP+5V supplied from the frame into the Vext pin to provide power to the GPO opto-
isolator circuitry. In this configuration the GPOs will be internally pulled up to 5 volts. (See Figure 3) Five
volts is available to the user to be used for driving external circuitry. Care must be taken to limit the load
to 0.5W so there is no affect on the power supply source on the module.
Alternately, the user can connect an external power source for the opto-isolator circuitry. The Vext voltage
must be greater than the voltage required by the GPO by at least 5v. Figure 4 shows how to wire the
GPOs from an external power supply.
Warning: Do not connect GP+5V from one module to another module’s
GP+5V.

5. CARD EDGE CONTROLS
The 7721DD is equipped with an 8 position DIP switch to allow the user to select various functions. All
positions are assigned sequentially such that the first position is located at the top of the DIP switch
(farthest from to the card ejector). Sections 5.1 to 5.2 show the assigned DIP switch functions. The On
position is down, or closest to the printed circuit board. Table 3 gives an overview of the DIP switch
functions.

5.1. SELECTING THE AUDIO GROUP AND CHANNEL WHERE THE DATA WILL BE
DE-EMBEDDED
The SMPTE 272M standard permits up to 4 groups of 4 audio/data channels to be embedded into the 270
Mb/s video bitstream.
The model 7721DD de-embeds one group of audio packets containing data (selected by switches 1 and 2)
onto the Data output port. Switches 3 and 4 select the channel within the group where data will be
extracted from.

5.3. SELECTING MINIMUM DELAY OR ERROR DETECTION AND CORRECTION MODE
DIP switch 6 controls whether the data deembedder will perform error detection and correction as it de-
embeds the data. Data verification causes a data error detection and correction scheme to be applied to
the extracted data to maintain data integrity. When data verification is enabled, there is an additional
delay before the extracted data can be sent to the data output serial port.

DIP 6 FUNCTION DESCRIPTION
Off Minimum
Delay Mode
Extracted data is passed through to the data output port with
minimum delay.
On Data
Verification
Mode (default)
Data error detection and correction is performed before data is
sent to the data output port. This mode requires additional delay
before the data is available on the output port.

5.4. SELECTING WHETHER EXISTING AUDIO/DATA WILL BE REMOVED
DIP switch 8 controls whether existing audio/data packets will be passed or removed from the video
stream.
DIP 8 FUNCTION DESCRIPTION

by DIP switches 1 & 2. Removes all audio/data packets. The H
blanking period after EAV is filled with the default blanking value.

7721DD-10 Revision 1.4.3
6.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
FRAME STATUS The FRAME STATUS jumper located at the front of the module determines whether
local faults (as shown by the Local Fault indicator) will be connected to the 7700FR
frame's global status bus.
To monitor faults on this module with the frame status indicators (on the PS FRAME
STATUS LED's and on the Frame's Fault Tally output) install this jumper in the On
position. (Default)
When this jumper is installed in the Off position, local faults on this module will not
be monitored.
6.2. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
UPGRADE The UPGRADE jumper J16 located at the front of the module is used when firmware
upgrades are being done to the module. For normal operation it should be installed
in the RUN position. See the Upgrading Firmware section of this manual for more
information.
To upgrade the firmware in the module unit pull it out of the frame. Move Jumper
J16 into the UPGRADE position. Install the Upgrade cable provided (located in the
vinyl pouch in the front of this manual) onto header J24 at the card edge. Re-install
the module into the frame. Run the upgrade as described in the Upgrading
Firmware section of this manual. Once the upgrade is completed, remove the
module from the frame, move J16 into the RUN position, remove the upgrade cable
and re-install the module. The module is now ready for normal operation.
6.3. CONFIGURING THE SERIAL PORT FOR RS 232 OR RS 422 OPERATION
J17 Jumper J17 located at the side of the module is used to select whether the serial
port receiver/driver hardware is configured for balanced RS422 or RS232 with flow
control. For RS 422 operation install jumper J17. For RS 232 operation remove
jumper J17. For convenience you may re-install the jumper so that only one side is
connected.
6.4. SETTING THE EQUALIZER WARNING THRESHOLD
The Cable Length Warning Adj trimpot located near the Signal Present LED is used to set the threshold of
the cable equalizer warning. The equalizer warning is factory set to 250 meters of Belden 8281 cable, but
may be adjusted for other cable types or cable lengths. To adjust the cable equalizer warning threshold,
connect a signal to the input of the module using the required length of cable. Adjust the trimpot slowly
until the Equalizer warning LED comes on. You can verify that the equalizer warning is operating correctly
by removing a few meters of cable from the input. The LED should go off.
