Abstract: A bidirectional media communication channel testing platform includes an HDMI testing device including a video input port and an audio output port; a plurality of media streaming devices, each including a video transmission channel and an audio return channel; and a bidirectional switch including a video path and an audio path. The video path is configured to selectively couple the video input port of the HDMI testing device to a video transmission channel of a selected one of the plurality of media streaming devices, and the audio path is configured to concurrently couple the audio output port of the HDMI testing device to the audio return channel of each of the plurality of media streaming devices, regardless of a switching state of the video path of the bidirectional switch.
