Abstract
The method of providing a mobile IPTV service, performed in a terminal that receives streams of all channels belonging to a channel group of a currently viewed channel, includes, when a channel is selected, determining whether the selected channel and the currently viewed channel belong to the same channel group, and when the selected channel and the currently viewed channel are determined to belong to the same channel group, decoding, by the terminal, an IPTV channel stream of the selected channel within a currently received channel. Therefore, since the channel group is generated based on channel selection preference, and a multicast stream including a channel stream of the channel group is broadcast, it is possible to decrease average processing complexity and to guarantee rapid channel change when a user changes the channel to another channel in the same channel group.
