Abstract:
1. A method for managing a preference channel in a mobile broadcast system, the method comprising: receiving multiplexed logical channels on which data streams are transmitted from a service provider to a mobile terminal through a communication network; demultiplexing the multiplexed logical channels; dynamically allocating preference channels among the demultiplexed logical channels to decoding buffers using preference channel description information; computing a decoding time of an elementary stream in each decoding buffer; decoding an elementary stream in each corresponding one of the preference channels by a single decoder based on the decoding time; and composing the decoded elementary streams of logical channels with a media, wherein the preference channel description information comprises the number of preference channels selected by a mobile terminal user; wherein a first decoding time is computed based on a start time and a slot time, and an n-th decoding time is computed based on a (n−1)-th decoding time and a period time; and wherein the start time is a time at which a first access unit (AU) starts to be decoded, the period time is a period of a time required to decode each elementary stream included in a source list once, and the slot time is a decoding time allocated to each elementary stream.
