Abstract
Systems and methods for HDMI signal communication over an optical communication link are described. One aspect includes receiving an HDMI control signal from an HDMI master device, and another HDMI control signal from an HDMI sink terminal via a communication resources. The method identifies half-duplex communication resource contention between the HDMI control signal and the other HDMI control signal, and transitions a communication direction of the half-duplex communication resources to give the HDMI control signal precedence over the other HDMI control signal. Subsequent to transitioning the communication direction, the method transfers the HDMI control signal to the HDMI sink terminal via the communication resources. Subsequent to transferring the HDMI control signal, the method again transitions the direction of the half-duplex communication resources, and transfers the other HDMI control signal to the HDMI master device.
