Title: BROADCAST CONTENT ENCAPSULATION
Abstract:
Components of a transmitted service delivering multiple versions of content are mapped to streams carrying data for those multiple versions. The data streams are encapsulated into User Datagram Protocol (UDP) packets; the UDP destination port fields of the packets are given component-identifying values. A user equipment (UE) receiving the transmitted service identifies desired components based on the UDP destination port field values. The UE further encapsulates desired component UDP packets into Internet Protocol (IP) packets, and may assign component-identifying values to fields of the IP packets (e.g., the IP source address and/or IP destination address).
