7721DE Serial Digital Data Embedder
Revision 1.5 7721DE-1
1. OVERVIEW
The 7721DE SDI data embedder inserts an RS-232/422 serial data stream and GPI contact closure
information into a 270 Mb/s SDI video signal. The RS-232/422 serial data and GPI information are first
formatted into an AES audio signal, then embedded into the video stream according to SMPTE 272M-A
specification. A data error detection and correction scheme is also applied to maintain data integrity for
the data de-embedder at the receiver end. 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
•One RS232/422 serial input with selectable baud rate (9600, 14,400, 19,200, 38,400 or 57,600)
•Parity selection: none, even or odd
•Support serial input with BREAK character according to SMPTE 207M
•Packetize data into the sub-frame AES format according to SMPTE 337M
•Embedding mechanism based on SMPTE 272M-A
•Share the same group DIDs as for embedded audio, selectable from group 1 to 4
•Channel selection for mapping data into one of four channels within a group
•Redundant data transmission to allow data error detection and correction at the receiver end
•Automatically remove the existing embedded packets when the conflict of group DID occurs
•Remove packets with "Marked packets for deletion" and "Data end marker packet"
•Six TTL level GPI inputs to embed simple control information into the video input
•EDH generation on video output
•Card edge LEDs indicate video signal and data presence, cable equalization and module fault

2. INSTALLATION
The 7721DE modules each come with a companion rear plate that has 3 BNCs and a female high-density
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 2-1: 7721DE 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 the input video with the data from the
RS-232/422 and GPI ports embedded in accordance with the SMPTE 272M standard. 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 GPIs are active low with an internal pull up (4.7k Ohm) resistor to the Vext pin. The user can connect
GP+5V supplied from the module into the Vext pin to provide power to the GPI opto-isolator circuitry. In
this configuration the user can activate GPIs simply by connecting the GPI input pins to Ground (refer to
Figure 2-2). This can be done with a button, switch, relay or an open collector transistor. 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. The GPI information is embedded into
the data stream and will activate the corresponding GPO outputs on the 7721DD Data De-embedder.
They can be used to pass simple contact closure information along with the video signal. Alternately, the
user can connect an external power source for the opto-isolator circuitry. The Vext voltage must be
greater than the voltage supplied to GPI by at least 5v. Figure 2-3 shows how to wire the GPIs from an
external power supply.
