OVERVIEW

The model
7700SID-CM
decodes Source ID/status information that has been encoded into VITC by source ID Encoders such as
the model 5010-SIE.
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.
