摘要： Provided is a multichannel video reception apparatus of a mobile communication terminal for digital broadcasting. An RF processor receives a broadcast signal of a digital broadcast service via an antenna. A baseband processor processes the received broadcast signal in a baseband. A controller controls the RF processor and the baseband processor to receive the broadcast signal including video frames of a main channel and a sub-channel. A memory stores a program code, reference data, and updatable user data, for an operation of the controller. A video processor receives the video frames of the main channel and the sub-channel, decodes the latest key frame of the sub-channel if a key frame of the main channel occurs while decoding the video frames of the main channel, and after decoding the key frame of the sub-channel, decodes the frames of the main channel. A display divides the decoded video signal into a main-channel image and a sub-channel image and separately displays the images. An audio processor outputs an audio signal of the digital broadcast service included in the broadcast signal.

摘要： A play-out apparatus and method for switching a channel in a digital multimedia broadcasting receiver are provided which can decrease a delay occurring in a channel switching time. A demultiplexer demultiplexes a signal received from a transmitter and outputs video data. A time stamp adapter changes a time stamp for indicating a play-out time of the video data such that the video data can be immediately output from a playback buffer without a Coder-Decoder (CODEC) delay, and outputs the video data including the changed time stamp. The playback buffer buffers and outputs the video data output from the time stamp adapter according to the changed time stamp. A video decoder decodes and outputs the video data output from the playback buffer according to the changed time stamp. A display unit plays the decoded video data out.
