Abstract

A video processing device receives a request to forward a video stream from a video source to a remote wireless device and, based upon characteristics of the video stream, determines data throughput requirement sufficient to transport the video stream. The video processing device establishes a wireless communication link with the remote wireless device via a servicing wireless network with wireless link parameters that support the data throughput requirement. The video processing device may be required to establish/alter the wireless communication link with the remote wireless device via differing wireless link parameters that support a differing data throughput that is less than the data throughput requirement and process the video stream to alter its characteristics to meet the differing data throughput. In either case, the video processing device transmits the video stream to the remote wireless device via at least the differing wireless communication link.
