5950-SID Manual Change Sheet 1.0-1
Date of Issue: March 1996 Page 1 of 1
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).

Model 5950-SID VITC Reader / Source ID Decoder Manual
INTRODUCTION Page 1-1
1. INTRODUCTION
The model 5950-SID VITC Reader / Source ID Decoder combines the latest
LSI technology with sophisticated microcontroller firmware to provide a
powerful, flexible reader system. The model 5950-SID is a VITC reader and
multi-function character inserter to display the decoded source ID
information. A 12 digit alphanumeric display can be quickly delegated to
show the required data.
The 5950-SID has been designed to decode Source ID/status information
which has been encoded by source ID Encoders such as the model 8025-
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 5950-SID 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 5950-SID automatically
blanks the status display.
The model 5950-SID contains all the necessary video processing circuits
and therefore, requires no external signals other than the video signal itself.
The VITC reader's line range can be easily programmed from the front
panel, thus permitting recovery of specific VITC data where multiple sets
have been recorded.
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.
When displaying data recovered from a VITC source, the 'lookahead'
compensation can be turned off, allowing field accurate burn-ins of edited
material. The field number sequence will be displayed to the right of the
frames display. When the data being read was recorded in the non colour
frame mode, the field number sequence will be 1,2,1, etc. (1,2,3,4,1, etc.
for PAL). When the reader data was recorded in the colour frame mode,
the field number sequence will be 1,2,3,4,1, etc. (1,2,3,4,5,6,7,8,1, etc. for
PAL).
The Character inserter provides an on screen programming menu system,
which is used to configure the various operating modes. The use of drop
down menus, and dedicated programming keys, allows the model 5950-SID
to be conveniently configured for particular customer requirements.

2.3. POWER REQUIREMENTS
2.3.1. Selecting the Correct Mains Voltage
Power requirements are 115 or 230 volts AC at 50 or 60 Hz, switch
selectable on the rear panel. Power should be applied by connecting a 3
wire grounding type power supply cord to the power entry module on the
rear panel. The power cord should be minimum 18 AWG wire size, type
SVT marked VW-1, maximum 2.5 m in length.
Before connecting the line power, be sure to select the proper line voltage.
Also, check that the line fuse is rated for the correct value marked on the
rear panel.
The power entry module combines a standard IEC 320 power inlet
connector, voltage selector switch, two 5 x 20 mm fuse holders (one active,
one spare) and an EMI line filter.
To change the mains voltage setting, open the cover of the power entry
module using a small screwdriver. Remove the drum selector switch, and
re-insert it so that the desired voltage is visible through the opening on the
mains connector cover. Check that the correct fuse is in use as shown in
section below.
2.3.2. Changing the Fuse
The fuse holder is located inside the power entry module. To change the
fuse, open the cover of the power entry module using a small screwdriver.
The fuse holder on the bottom contains the active fuse. The one at the top
contains a spare fuse. Pull the bottom fuse holder out and place a fuse of
the correct value in it. Use slo blo (time delay) 5 x 20 mm fuses rated for
250 Volts with the following current ratings:
For 115 Volt operation 250 mA
For 230 Volt operation 125 mA
Never replace with a fuse of greater value.
Make sure that the arrow is pointing down when you replace the fuse
holder. Close the door on the power entry module and connect the mains
voltage.

by the same relative amount. For example, to move the time and
source ID/status windows both down by one line press the $key.
3.3.3. 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. The CHAR GEN ON/OFF key on the front panel alternately turns
the characters on and off.
2 The VCG Keyer On/Off remote control input on the rear panel
alternately turns the characters on and off. This input has equal
priority with the front panel On/Off key.
3. The individual windows can be turned off using the CHAR GEN
ON/OFF key in window select mode.
4. 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.
3.3.4. Special VCG Indicators
The following special indicators are used between the seconds and frames
digits of the time windows in the character inserter to identify non drop
frame and drop frame code (NTSC only)
Non Drop Frame Colon (:)
Drop Frame (NTSC) Period (.)
3.3.5. Field Identification
When reading VITC, the field number sequence may be displayed to the
right of the reader time frames display. When the data being read was
recorded in the non colour frame mode the field number sequence will be
1, 2, 1, etc. (1, 2, 3, 4, 1, etc. for PAL). When the reader data was
recorded in the colour frame mode, the field number sequence will be 1, 2,
3, 4, 1, etc. (1, 2, 3, 4, 5, 6, 7, 8, 1, etc. for PAL) The field number display
may be disabled using the VCG FIELDS item in the VCG menu.
3.4. ON SCREEN PROGRAMMING MENU - OVERVIEW
The key to the operational flexibility of the model 5950-SID lies in the
powerful on screen programming menu system which uses the built in
