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.
