Abstract: Today’s 3G networks enable the delivery of mobile television services to the user. However, the distribution mechanism differs from conventional television broadcasting. For an effective mobile TV system both unicast and multicast transmission are combined. One weak point of digital television is channel switching. Both the underlying network and the data structure impose partially unavoidable delays. In this paper we present a mobile television architecture which supports fast stream switching and present different techniques to reduce at least the perceived switching duration. The different switching scenarios between unicast and multicast are discussed in detail. This paper presents work in progress, so both already implemented and future extensions are described. Though the implementation has been done with a 3G background the algorithms can be applied to every digital television scenario.
