The following document describes the operational changes to the 5950-SID Source ID decoder related to
firmware version 960321. References to the 5950-SID manual are to version 1.0 printed October 1995.
1. New Features
•
Decoding of new 9 character VITC SID format
•
Decoding of source ID from PESA Source ID Encoders - only displayed when no VITC SID is
present.
•
LTC Reader input added - only displayed when VITC SID, PESA SID and normal VTR VITC are not
present
2. Support for 5 and 9 character VITC Source ID formats.
The 5950-SID automatically detects whether incoming VITC with source ID is encoded in one of two formats, and
appropriately displays each one. The first format consists of 5 alpha-numeric 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 5950-SID and is always displayed if present.
3. PESA Source ID Decoding Implemented
When VITC with source ID is not present, the 5950-SID will decode any incoming PESA format source ID. The
VITC Code In LED will be on when PESA source ID is detected on the incoming video. 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. The front panel display will switch to the PESA source ID message. The front panel
display will show PID: source msg.
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, and the front panel display will revert to the last display it was showing.
4. LTC Reader Added
An LTC reader has been added to the 5950-SID. The LTC CODE IN LED will be on when LTC is present. This
reader is only displayed when there is no VITC or PESA data available on the incoming video. The Source ID
and Status VCG windows will be automatically turned off if they are visible, and the LTC reader time will be
shown in the Time window. The front panel display will switch to the LTC reader time and the LTC DISPLAY LED
will be turned on.
When a source that contains either VITC or PESA source ID returns, the character windows will be restored to
the last state they were in, and the front panel display will revert to the last display it was showing.
The LTC reader input connects to any LTC source such as the head preamplifier of a VTR or a house timecode.
The LTC Reader In XLR provides a balanced input, with the signals connected to pins 2 and 3. When using an
unbalanced input to the reader, the signal should be applied to pin 3 of the XLR, and the unused input (pin 2)
should be connected to ground (pin 1).
