Abstract

A video or multimedia distribution system receives multiple video streams and transcodes them into a single stream of UDP packets with each of the plurality of video data packets for respective ones of the video streams being assigned a port number corresponding to the respective video stream. The UDP packets are routed to a plurality of Access Points (APs) for transmission. A User Equipment (UE) communicates with the APs and selects one of the video streams for viewing on the UE by selecting the port number corresponding to the desired video stream. A first processor in the UE identifies and stores UDP packet data having the selected port number and a second processor retrieves and plays the video stream on a display. The UE can "change channels" to view other video streams by changing the port number to the port number of the desired video stream.
