7700SID-CM Analog Source ID Decoder
1. OVERVIEW
The model 7700SID-CM is an analog VITC reader and multi-function character inserter that display
decodes Source ID/status information that has been encoded into VITC by source ID Encoders such as
the model 5010-SIE. The VTR time is encoded in the usual way for sources that have timecode
associated with them. For non-timecoded sources such as cameras, the 7700SID-CM senses codes in
the user bits to automatically blank the time display on the character inserter. A 5 character source ID
message and a 3 digit source number are encoded into the user bits. For VTR sources, VTR status is
also encoded into the user bits. For sources that do not have encoded status information, the 7700SID-
CM automatically blanks the status display.
The high resolution character inserter provides two independently positionable windows to show time and
source ID/status (decoded from the user bits) simultaneously. Three character sizes and the choice of
white or black characters with or without contrasting background mask are selected from the front panel.
The character inserter provides an on screen programming menu system, which is used to configure the
various operating modes.
The VITC reader's line range can be easily programmed using the card edge controls, thus permitting
recovery of specific VITC data where multiple sets have been recorded. The 7700SID-CM automatically
detects whether incoming VITC with source ID is encoded in one of two formats, and appropriately
displays either one. The first format consists of 5 alphanumeric characters followed by a number from 000
to 999. The source message and number are separated by a dash (-) in the Source ID display. The
second format consists of 9 alphanumeric characters. VITC with source ID encoded in either format
receives the highest priority in the 7700SID-CM and is always displayed if present.
When VITC with source ID is not present, the 7700SID-CM will decode any incoming PESA format source
ID. The Time and Status VCG windows will be automatically turned off if they are visible, and the PESA
source ID message will be shown in the Source ID window. When a video input that contains VITC with
encoded source ID returns, the character windows will be restored to the last state they were in.
Features:
• VITC Source ID decoder displays Time, Source ID and machine status
• PESA Source ID decoder displays Source ID
• Independently positionable windows
• Three character sizes, white or black char with optional background
• On screen programming menu
• VITC Reader Lines selectable
• Front panel LEDs indicate video signal presence, and module fault

2. INSTALLATION
The 7700SID-CM modules each come with a companion rear plate that has 3 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: 7700SID-CM Rear Panel
ANALOG INPUT Input BNC connector for an NTSC or PAL analog video signal with Source ID
encoded into vertical interval time code user bits.
ANALOG OUTPUT There are two BNC connectors with identical outputs of program video with source
ID characters inserted. These outputs are also used to display the On screen programming
menu and are normally connected to a video monitor. Size, position, and style of the character
displays are controlled from the on screen programming menu.

4.1. MODULE STATUS LEDS
MODULE OK This Green LED will be On when the module is operating properly.
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.
The LED will be on solid when input video is missing or there is a fault in the module
power supply.
SIG This Green LED will be On when there is a valid video signal present at the module
input.
-5VDC This Green LED will be On when there is a valid –5 VDC power from the module
power supply.

5. CARD EDGE CONTROLS
The 7700SID-CM is equipped with an 8 position DIP switch that is used to invoke various diagnostic and
calibrations functions. A three position, return to center toggle switch is used in conjunction with a
momentary pushbutton to operate the On screen Setup menu. Section 5.1 shows the assigned DIP
switch function for switch 6. The remainder of the switches are reserved for future use and should be in
the Off position for normal operation. The On position is down, or closest to the printed circuit board.
5.1. RESETTING THE 7700SID-CM TO FACTORY DEFAULTS
DIP switches 6 is used to control whether the 7700SID-CM will reset to factory defaults on power up or will
recall it’s last configuration.
DIP 6 Factor Reset
Off Recall last configuration
On Reset to factory defaults on power up

5.2. CHARACTER GENERATOR FUNCTIONS
Two separately positionable character windows displaying time or Source ID/Status (user bits) are
available. Although the Source ID and Status windows move together, they can be independently turned
on and off. The toggle switch in combination with the pushbutton control which windows are displayed
and their position on the screen. The VCG menu of the On screen programming menu is used to select
character size and style, and whether the symbols or fields will be displayed.
5.2.1. Selecting and Positioning the Individual Character Inserter Windows
Hold the toggle switch down and press the pushbutton to enable the window select mode. The message
ON OFF MODE will appear in the center of the screen. Both windows will appear on the character screen
with the window for the time highlighted. Press the toggle switch up or down to turn the highlighted
window on or off. Press the pushbutton to enter horizontal position mode. The message HORZ MODE will
appear in the center of the screen. Press the toggle switch up to move the highlighted window to the left,
or down to move it to the right. Press the pushbutton to enter vertical position mode. The message
VERT MODE will appear in the center of the screen. Press the toggle switch up to move the highlighted
window up, or down to move it to down. Press the pushbutton to select the Source ID window the in
window on/off mode. The Source ID window will be highlighted and the message ON OFF MODE will
appear in the center of the screen. Follow the procedure outlined above to enable and position the Source
ID and Status windows. When you are finished setting up the Status window, the message in the centre
of the screen will disappear, indicating that you have exited window select mode and have returned to the
normal display mode.

5.2.2. Character Generator On/ Off Controls
There are several factors that control whether the character generator windows will be turned on or off. In
order of priority these are:
1. All the windows can be turned on and off by pressing the pushbutton when the 7700SID-CM is in
the normal operating mode.
2. The individual windows can be turned off using the Window on/off mode described in 5.2.1.
3. If the source does not have timecode associated with it, (SRC TIME flag in user bits is off) the time
window will be turned off.
If the source does not have status associated with it, (SRC STATUS flag in user bits is off) the
status window will be turned off.
