7760CCM and 7760CCM-T Closed Caption & XDS Monitoring Display
1. OVERVIEW
The 7760CCM closed captioning monitoring card extends the signal monitoring capabilities of Evertz’s
AVM product line by focusing on closed captioning and eXtended Data Services (XDS) data packets
carried within Line 21 of the Vertical Blanking Interval (VBI). Compliant with the EIA Standard EIA/CEA-
608-B, the 7760CCM can be used to monitor the content of Line 21 for pre-distribution monitoring or
regulatory compliance.
The 7760CCM-T Closed Captioning, XDS and EIA608-EIA708 Translator card is functionally similar to the
7760CCM card, with the additional features of a EIA608 to EIA708 Standard translator through the RS-
232 serial communication port.
Both 7760CCM and 7760CCM-T are capable of decoding Line 21, fields 1 and 2 data and displaying the
information on the SDI video output. One of four closed captioning channels (CC1-CC4) and one of four
text service channels (T1-T4) can be simultaneously displayed on the video output. In addition, the
scrolling XDS display supports all data packets. The more common packet types such as V-Chip rating,
Station Name, Station ID, Program Name, Program Type, Program Description, Time of Day, and Time in
Show are decoded to human-readable format. Other (less common) packets are presented as raw data
bytes.
The 7760CCM-T card is equipped with CCM/CCM-T mode setting, closed captioning and text channel to
708 service mapping configuration, as well as a data delay queue used to match the delay of the data to
that of the upconverted video prior to encoding.
The 7760CCM and 7760CCM-T incorporate the fault reporting capabilities inherent in the AVM product
line. There are four user-configurable fault alerts that are triggered upon loss of video, loss of CC
waveform, parity errors, field inversions, control codes and invalid XDS parameters. The 7760CCM is also
VistaLINK™-enabled, offering remote monitoring, control and configuration capabilities via Simple
Network Management Protocol (SNMP).
The single-slot, 7760CCM and 7760CCM-T modules fit conveniently into Evertz’s 7700FR-C, 7701FR
frames or stand alone enclosure.
7760CCM/7760CCM-T Features:
• One SD, 270 Mb/s component digital video input, 525 or 625 lines, auto-detected or manually set.
• One re-clocked SD video output.
• Decodes and displays closed captioning on fields 1 and 2 as per EIA Standard EIA/CEA-608-B.
• EIA-608 to EIA-708 translator (7760CCM-T only)
• Support for SMPTE-333M and Grand Alliance Protocol in 7760CCM-T
• User selectable closed captioning channel (1-4), text channel (1-4) and eXtended Data Services (XDS)
for video “burn-in”.
• Decodes Line 21 XDS packets containing Transmission Signal ID (TSID), Copy Generation
Management System (CGMS), Program ID, Time in show, Program name, Program type, V-chip
rating, Program description, Network name, Station ID, Time of day and Time zone.
• Store and recall up to three module configurations.
• Fits conveniently into Evertz’s 7700FR-C 3RU, 7701FR 1RU frames and stand-alone enclosure.

• Four user-configurable GPI inputs for on screen display control, closed captioning channel and text
channel selection.
• Two user-configurable GPI outputs to indicate user definable fault conditions.
• RS-232 serial port output used to transmit raw closed captioning data. (Compliments VBI Bridge
functionality of Evertz 8084 CC Encoders)
• HDDB-15 to DB-9 cable available to connect 7760CCM(-T) to Evertz captioning products (Evertz Part#
WACCMIO-1-0-6F)
• VistaLINK™-enabled offering remote monitoring, control and configuration capabilities via SNMP.
VistaLINK™ is available when modules are used with the 3RU 7700FR-C frame and a 7700FC
VistaLINK™ Frame Controller module in slot 1 of the frame. (Available soon)
1.1. FUNCTIONAL DESCRIPTION
Serial digital video is converted to parallel and Line 21 closed captioning and text channels, extracting time
code, program rating and description as well as other pertinent information. Line 21 status information can
be displayed on-screen. The hardware mixes (keys) the on screen text display information onto the video
stream. This video goes out digitally through a parallel to serial converter.
The 7760CCM and 7760CCM-T cards are also configurable to trigger fault alert messages. If decoded
data from Line 21 is missing or invalid, fault alerts can be enabled to report such findings directly on to the
output video display.
The CPU also gets pushbutton and toggle switch commands from the card edge controls and draws
extensive menus for configuring the operation of the card.
General-purpose inputs are used for remote control of several features and general-purpose outputs are
generated under error conditions. GPI I/Os are available through the high-density DB-15 connector on the
rear plate of the 7760CCM and 7760CCM-T.

2.2.1. General Purpose Inputs and Outputs
The GPI’s are active low with internal pull up resistors (4.7k Ohms) to +5V. To make an input active, lower
the signal to near ground potential (i.e. connect to shell or chassis ground). This can be done with a
switch, relay, TTL drive, GPO output or other similar method. Figure 3 shows the input circuit for the
General Purpose inputs.

5. ON SCREEN MENUS
5.1. NAGIVATING THE ON SCREEN MENU SYSTEM
A toggle switch and pushbutton allow card edge navigation of a set of on-screen menus used to configure
the card.
To enter the on-screen menu system, press the pushbutton once. This will bring you to the main setup
menu where you can use the toggle switch to move up and down the list of available sub menus. An arrow
(>) moves up and down the left hand side of the menu items to indicate which item you are currently
choosing. Once the arrow is on the desired item, press the pushbutton to select the next menu level.
On all menus, there are two extra selectable items: Back and Exit. Selecting Back will take you to the
previous menu (the one that was used to get into the current menu) while Exit will return the display to its
normal operating mode. On the main menu, BACK and EXIT will both take you to the normal operating
mode.
Once in a sub menu, there may be another menu layer, or there may be a list of parameters to adjust. If
there is another set of menu choices, use the toggle switch to select the desired menu item and press the
pushbutton.
To adjust any parameter, use the toggle switch to move up or down to the desired parameter and press
the pushbutton. The arrow will move to the right hand side of the line (<) indicating that you can now
adjust the parameter. Using the toggle switch, adjust the parameter to its desired value. If the parameter
is a numerical value, the number will increase if you lift the toggle switch and decrease if you push down
on the toggle switch. If the parameter contains a list of choices, you can cycle through the list by pressing
the toggle switch in either direction.
When you have stopped at the desired value, depress the pushbutton. This will update the parameter to
the selected value and move the arrow back to the left side of the parameter list (>). Continue selecting
and adjusting other parameters or use the BACK or EXIT commands.
5.2. CHANGING TEXT FIELDS
Some of the controls of the OSD menu allow you to adjust a text-based field. Editing a line of text can be a
little tedious with a toggle switch and a pushbutton, but it can be done with the following procedure:

4. There are two special characters to help you enter the text: a backspace character (left pointing
arrow), and an end of line character (stop sign):
Left Arrow: If you have accidentally advanced to the next character and want to go back, select the left
arrow with the toggle switch. When you press the pushbutton, you will go back to the previous
character. This will save you from having to complete the editing and re-edit it to change the mistake.
Stop sign: If you are done changing the text, and the new text is shorter than old text, you can terminate
the line with a stop sign. When you use the pushbutton after selecting the stop sign, any remaining
characters in the text field will be erased and you will return to the menu structure.
5. You are done editing when you reach the end of the field (maximum length), or you select the stop
sign and press the pushbutton.
