Apparatus and method for processing multimedia audio signal for a voice call in a mobile terminal capable of receiving digital multimedia broadcasting service

A mobile terminal capable of receiving a digital multimedia signal having compressed-coded audio and video signals multiplexed, comprising:

• an Radio Frequency (RF) module for receiving an RF signal for a voice call and converting the RF signal to a coded signal;
• an audio processor for converting the coded signal to an electrical voice signal and outputting the electrical voice signal through a speaker;
• a demultiplexer for receiving a digital multimedia signal and separating the digital multimedia signal into an audio signal and a video signal;
• a decoder for decoding the audio and video signals and providing the decoded audio signal to the speaker and the decoded video signal to a display;
• and
• a controller for controlling decoding the audio signal in the decoder to be discontinued and controlling the voice signal to be output from the audio processor through the speaker, if a digital multimedia request is generated during the voice call.

A method of processing an audio signal in a mobile terminal capable of receiving a digital multimedia signal having the compressed-coded audio and video signals multiplexed, comprising the steps of:

• receiving a digital multimedia signal and separating the digital multimedia signal into an audio signal and video signal;
• decoding the audio and video signals and outputting the decoded audio signal to a speaker and the decoded video signal to a display;
• discontinuing decoding the audio signal when a voice call request is generated during receiving the digital multimedia signal;
• and
• receiving an Radio Frequency (RF) signal for a voice call, converting the RF signal to an electrical voice signal, and outputting the electrical voice signal through the speaker.
