When reproducing a multimedia file received by a receiving section, a control section controls a sound reproduction section to reproduce a sound on the basis of sound data. Further, the control section controls a display section to display an image on the basis of image data if the multimedia file contains the image data, and controls the display section to display a prepared substitute image if the multimedia file contains no image data. |

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the invention will be descried with reference to the accompanying drawings.
FIG.
1 is a block diagram illustrating a mobile telephone according to the embodiment of the invention.
As shown in FIG.
1, the mobile telephone of the embodiment comprises an antenna 1, radio section 2, CDMA processing section 3, compression/expansion section 4, PCM processing section 5, call section 6, user interface section 7, motion picture processing section 8, display control section 9, memory section 10, timing circuit 11 and CPU 12.
The radio section 2 incorporates a duplexer (DUP) 2a, receiving circuit (RX) 2b, frequency synthesizer (SYN) 2c and transmission circuit (TX) 2d.
The call section 6 incorporates a receiver amplifier 6a, receiver 6c, microphone 6c and transmission amplifier 6d.
The user interface section 7 incorporates a display section 7a and input section 7b.
A radio signal transmitted from a base station (not shown) is received by the antenna 1 and input to the radio section 2.
In the radio section 2, the radio signal is input to the receiving circuit 2b via the duplexer 2a.
The receiving circuit 2b mixes the radio signal with a receiver-side local oscillation signal output from the frequency synthesizer 2c, thereby converting the radio signal into an intermediate frequency signal.
The frequency of the receiving-side local oscillation signal output from the frequency synthesizer 2c is set on the basis of a control signal output from the CPU 12.
The intermediate frequency signal is input to the CDMA processing section 3, where it is subjected to a despread process using a spread code assigned to each receiving channel.
Subsequently, the CDMA processing section 3 executes orthogonal demodulation corresponding to, for example, QPSK (Quadrature Phase Shift Keying) modulation, thereby converting the signal into demodulation data or packet data of a predetermined format.
After that, the CDMA processing section 3 supplies the converted demodulation data to the compression/expansion section 4, and supplies the packet data to the CPU 12
