Apparatus and method for receiving multiple streams in a mobile broadcast system
First Claim
Patent Images
1. A method for receiving multiple streams 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;
decoding an elementary stream in each corresponding ones of the demultiplexed logical channels by a single decoder based on a group descriptor comprising a list of stream identifiers (IDs) identifying streams to be decoded in one group at a decoding time determined for each decoding buffer; and
composing the decoded elementary streams of logical channels with a media.

Abstract
An apparatus and method are provided for receiving multiple streams. A group session structure is defined and streams are decoded according to the defined group session structure so that a single decoder can sequentially process demultiplexed streams allocated to multiple decoding buffers when multiple logical media streams are multiplexed into one physical stream in a mobile broadcast communication system based on Lightweight Application Scene Representation (LASeR).
