3.5.2 HD AND SD
As mentioned earlier, the VIDEO OUT section on 3Play’s backplate provides vertical columns of
four BNC connectors. These represent:

Channel A (labeled 1 in the VIDEO OUT group)

Channel B (labeled 2 in the VIDEO OUT group)

3Play 4800 only – Aux (labeled 3 in the VIDEO OUT group); carries the same signal as
either Channel A or Channel B, depending on 3Play’s current Channel Delegate (see
Section 7.1.2).
The output connectors provide either SD or HD video output, according to the format specified
for the current session, using any of several different device connection types as discussed next.
3.5.3 CONNECTING DEVICES
1. Connect downstream video devices to the appropriate output connectors in the VIDEO
OUT section, whether SDI, Component, Y/C (BNC), Composite, or HDMI (3Play Mini).
Please note that Y/C (BNC) and Composite may require RCA (cinch plug) or S-video (4 pin
mini-DIN) to BNC adapters, and also that both of these connection options support
output at SD resolution only.
a. SDI – Attach SDI connectors to the uppermost row of BNC connectors in the
VIDEO OUT connector groups.
Tip: If your equipment supports SDI connections, this is your best quality option.
b. Component – Attach your device to the second, third and fourth BNC
connectors (Y, Pb and Pr) in the VIDEO OUT connector groups.
c. Y/C – If your S-Video equipment and cabling has the usual 4-pin mini-DIN
connectors, you will need an ‘S-Video to dual BNC’ adapter. Attach the Y
(luma) connector of your device to the second analog BNC connector row
(labeled Pb). Attach the C (chroma) connector to the third analog connector
(labeled Pr).
