A bidirectional transceiver includes a media transmitter, a media receiver, a network transmitter, and a network receiver. Each of these components includes an interface to a respective differential wire pair of a cable. By coupling a pair of such transceivers, a media stream and network connectivity can be sent over the cable in either or both directions. Using an opportunistic scheduling method, each media stream can contain audio, video, and control information in uncompressed form. Power can be transferred over the cable so that a media device containing one transceiver can be powered by a media device containing the other transceiver.
