摘要： 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.

摘要： Provided are a method of packetizing encoded symbols and an apparatus using the same. The method includes an encoded symbol and target packet selection step of deciding a first source symbol and selecting an unpacketized first encoded symbol and a target packet into which the unpacketized first encoded symbol is inserted if there is the unpacketized first encoded symbol of at least one first encoded symbol, which is an encoded symbol of the first source symbol generated using an AND-OR tree structure, and a packetization step of generating a second source symbol based on at least one unpacketized first encoded symbol by use of the AND-OR tree structure, generating at least one second encoded symbol based on the second source symbol by use of the AND-OR tree structure, and packetizing at least one of second encoded symbols into the target packet along with the first encoded symbol.
