FIELD: physics, video.SUBSTANCE: invention relates to digital video broadcasting (DVB). The apparatus and method for channel switching comprise 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 multi-protocol encapsulation (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. The plurality of non-consecutive bursts is transmitted to a DVB-H receiver with a limited memory size for enabling fast channel switching, and the channel line-up is presented in an electronic service guide (ESG).EFFECT: faster channel switching and saving receiver memory.40 cl, 11 dwg |
