Abstract

A video processing system and method of operation transports a video stream between a video source and a remote wireless device and includes a communication interface and processing circuitry. The processing circuitry couples to the communication interface, establishes a reception verified communication link with the remote wireless device via the communication interface, and establishes a non-reception verified communication link with the video source via the communication interface. The processing circuitry further receives the video stream (and an audio stream) from the video source via the communication interface using the non-reception verified communication link and transmits the video stream (and audio stream) to the remote wireless device via the communication interface using the reception verified communication link.
