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.
