Abstract

Method and apparatus for providing broadcast overhead information interleaved with a broadcast session in a transmission on a broadcast channel of a wireless communication system (100). In one embodiment, the information stored at the receiver to provide quick updating when a user changes to an alternate broadcast channel. In one embodiment, the content server provides an identifier SDP_ID to distinguish among sets of protocol options description sets.
