Method and apparatus for enabling rapid channel switching with limited DVB receiver memory

摘要

An apparatus and method for channel switching comprising encapsulating a plurality of IP datagrams associated with a plurality of real time audio/visual (A/V) streams or a plurality of file objects onto a plurality of MPE sections; inserting the plurality of MPE sections into one of a plurality of elementary streams; and multiplexing the plurality of elementary streams associated with the plurality of real time A/V streams or the plurality of file objects into a plurality of non-consecutive bursts, wherein the plurality of elementary streams are adjacent in a channel line-up. In one aspect, the plurality of non-consecutive bursts is transmitted to a DVB-H receiver with a limited memory size for enabling fast channel switching. In one aspect, the channel line-up is presented in an electronic service guide (ESG).
