Model 8950-SID Digital Source ID Decoder Manual
OVERVIEW Revision 1.0 Page 1-1
1. OVERVIEW
The 8950-SID is a dual-purpose Source ID decoder that reads either
source ID information encoded into vertical interval timecode, source ID
encoded by the PESA source ID encoder system or Neilson Source ID
codes encoded on line 20. The 8950-SID decodes these signals directly
from the digital bitstream. The model 8950-SID VITC reader's line range
can be easily programmed from the front panel, thus permitting recovery of
VITC source ID data where it is encoded along with other VITC data.
The high resolution character inserter provides two independently
positionable windows to show time and source ID/status (decoded from the
user bits) or Neilson Source ID. Two character sizes and the choice of
white or black characters with or without contrasting background mask are
selected from the front panel.
Features:
• Keys source ID information recovered from D-VITC directly into digital
video bitstream
• Standard unit is equipped for component digital video
• Serial digital video input provides automatic cable equalization on cable
lengths up to 200 meters of low loss coax such as Belden 8281
• Serial digital video output provides two separate outputs
• Passes embedded audio and other ancillary data signals
• Character Inserter displays timecode, source ID and VTR status in the
picture
• Separate positioning of each character window
• Rack mountable
• 8 or 10 bit resolution
• 16 digit Alpha-numeric display, with 10 pushbuttons

EDH Error Detection and Handling (EDH) is defined in SMPTE
RP-165 as a method of determining when bit errors have
occurred along the digital video path. According to RP-165, two
error detection checkwords are used, one for active picture
samples, and the other on a full field of samples. Three sets of
flags are used to convey information regarding detected errors,
to facilitate identification of faulty equipment or cabling. One set
of flags is associated with each checkword, and the third is used
to evaluate ancillary data integrity. The checkwords and flags
are combined into a special error detection data packet that is
included as ancillary data in the serial digital signal.

PIXEL: The smallest distinguishable and resolvable area in a video
image. A single point on the screen. In digital video, a single
sample of the picture. Derived from the words picture element.
RESOLUTION: The number of bits (four, eight, ten, etc.) determines
the resolution of the signal. Eight bits is the minimum resolution
for broadcast television signals.
4 bits = a resolution of 1 in 16.
8 bits = a resolution of 1 in 256.

signals compatible with the SMPTE 259M standard.
SDI BYPASS: A BNC connectors for output of 10 bit serial digital video
signals compatible with the SMPTE 259M standard. This
video will normally be the video input with VITC (encoded
with source ID information) and characters inserted onto it.
When the SDI bypass relay is activated (on power failure or
from the front panel) the SDI BYPASS output is a direct
relay connection to the SDI IN.
SDI OUT: A BNC connectors for output of 10 bit serial digital video
signals compatible with the SMPTE 259M standard. This
video will be the video input with VITC (encoded with source
ID information) and characters inserted onto it. When the
SDI bypass relay is activated (on power failure or from the
front panel) the SDI OUT output will not have any video
signal on it.
2.1.2. Tally Connections
FAULT TALLY OUT: A BNC connector for output of a SMPTE 269M fault
tally. The output will be open circuit when the 8950-SID is

2.2. MOUNTING
The 8950-SID Digital Source ID Decoder is equipped with rack mounting
angles and fits into a standard 19 inch by 1 3/4 inch (483 mm x 45 mm)
rack space. The mounting angles may be removed if rack mounting is not
desired.

Model 8950-SID Digital Source ID Decoder Manual
INSTALLATION Revision 1.0 Page 2-3
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
SST 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
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.
Never replace with a fuse of greater value.

INSTALLATION Revision 1.0 Page 2-4
2.4. CONNECTING THE DIGITAL VIDEO
2.4.1. Video Input
The 8950-SID decoder requires that a digital video source with VITC (with
timecode, source ID and VTR status encoded) be connected to the SDI IN
video input. The 8950-SID decoder may be configured to accept either 525
or 625 line digital video in the component (4:2:2) format. The VIDEO TYPE
parameter on the front panel menu must be set correctly to match the video
input. (See section 3.6.1 for information on changing the video type
setting).
The Video LED indicator will be On when there is video present matching
the selected video type. When it is blinking it indicates that there is no
video present, or the wrong video type is selected.
2.4.2. Video Output
The SDI BYPASS and SDI OUT outputs contain the input video with
character data keyed in by the keyer. Connect one of these outputs to any
input on your system that accepts 8 or 10 bit SERIAL digital video. The
two outputs are identical except that the SDI BYPASS output is protected
by the bypass relay. When the relay is active, the SDI BYPASS output is
directly connected to the SDI input, and the SDI OUT output will have not
video output.
2.5. CONNECTING THE GENERAL PURPOSE INPUTS AND OUTPUTS
The 9 pin PARALLEL I/O connector has 1 general purpose input and 2
general purpose outputs. The GPI input is active low. This means that if
you leave an input floating (not connected) then it will not be activated.
Lowering the GPI input to a voltage below 0.8 volts will activate the input.
The user can activate GPIs simply by connecting the GPI input pins to
Ground using a button, switch, relay or an open collector transistor.
The outputs are internally pulled up to 5 volts. Care must be taken to limit
the load to 0.5W so there is no affect on the power supply source in the
frame.
Each I/O pin is electrically wired so it can be used as either an input or
output. When the pins are used as inputs, the software turns off the output
driver transistor. Figure 2-2 shows the circuitry for each of the I/O pins.
