Abstract:
PURPOSE: A digital multimedia broadcasting receiver and a method thereof are provided to efficiently reduce channel search and switch time by managing a preferred channel. CONSTITUTION: A channel manager(170) manages channel information included in stored logical channel information. A channel information updater(180) updates a sub IF signal. A user data collector(190) collects one or more selected preference channels, a famous channel, or a recommendation channel. A user data processor(200) classifies collected prediction channels. An external channel collector(210) collects a famous channel of the other person through communication with the other terminal.

Abstract:
PURPOSE: A multimedia supporting system for controlling the locking time of video and audio is provided to remove stream in the memory space and control the locking time of video and audio. CONSTITUTION: A multimedia support system(100) includes an encoder(10), a memory unit(20), a bit control unit(30), and a transmission unit(40). The encoder encodes input media. The memory unit stores the stream outputted from the encoder. The bit control unit controls output bit rate about the stored stream in the memory unit. The transmission unit controls the size about a data packet controlled by the bit control unit.
