Patent ID: 8270425

Claim:
A method for multicast video streaming over a wireless local area network (WLAN), the method comprising: configuring a WLAN access point with a reserved video bandwidth; receiving a multicast video stream including data packets marked with differentiated services code points (DSCPs); converting the multicast video stream to a plurality of “n” unicast streams; and streaming data packets in the unicast streams from the WLAN access point to a plurality of “n” mobile units using a selective packet discard algorithm that employs the DSCPs, wherein the selective packet discard algorithm comprises: receiving a packetized data stream comprising one or more data segments, wherein each data segment of the one or more data segments corresponds to a frame type of a plurality of frame types; determining a number of data segments to be transmitted for each frame type of the plurality of frame types in the WLAN based on at least one predefined parameter; dropping at least one data segment for at least one frame type of the plurality of frame types based on: a number of data segments to be transmitted for each frame type; a functional dependency between the one or more data segments; and a functional dependency between the plurality of frame types; and re-packetizing the received packetized data stream based on the dropping of the at least one data segment.
