DMP TV Control Connections
StadiumVision Director controls what is displayed on the TVs and also controls the
TV settings (e.g., turning the TV on or off, setting volume level, etc.). StadiumVision
Director sends commands over the IP network to the DMP. The DMP then sends
those commands to the TV via the RS-232 port of the DMP. There are two primary
ways to transmit those commands to the TV: a direct RS-232 cable connection or
an Infrared connection. The infrared option requires the addition of an RS-232-to-
Infrared (IR) adapter to make the command signal conversion from RS-232 to IR.

commands (such as volume and mute) can be issued directly to the DMP using the
DMP Sigma commands. Refer to
