Abstract

Disclosed is an image/audio playback technology in a mobile communication terminal. According to the present invention, a single image is divided into two halves, i.e., left-half and right-half images, which are displayed on two mobile communication terminals, respectively. In addition, two mobile communication terminals can play left-side and right-side audio data, respectively, which compose stereo audio data, according to the relative locations of the two mobile communication terminals.

Claims

1. An audio playback device of a mobile communication terminal, comprising:

a control unit which recognizes the relative location of the mobile communication terminal corresponding to another mobile communication terminal and offers left-side or right-side location information corresponding to the relative location;

a codec unit which decodes audio data and outputs decoded left-side and right-side audio data;

a path switching unit which transmits any one of the two decoded audio data to an audio output unit and transmits the remaining one to a communication interface unit according to the location information from the control unit;

an audio output unit which processes and outputs the one of the two divided audio data to the outside; and

a communication interface unit transmitting the remaining one of the two divided audio data to a corresponding communication interface unit provided in the other mobile communication terminal.

2. The audio playback device of claim 1, wherein the audio data decoded by the codec unit is transmitted from a mobile communication unit, a camera unit, a broadcast receiving unit, and/or a storing unit.

3. The audio playback device of claim 1,

wherein the mobile communication terminal includes a left-side connector and a right side connector, which are coupled with corresponding connectors provided in another mobile communication terminal,

the communication interface unit performs communication with a corresponding communication interface unit provided in the other mobile communication through the left-side or right-side connector, and

the control unit recognizes the relative location of the mobile communication terminal according to whether a connector coupled with the other mobile communication terminal is a left-side or a right-side connector.

4. The audio playback device of claim 3, wherein the left-side connector is a receptible and the right-side connector is a plug, or the right-side connector is a receptible and the left-side connector is a plug.

5. The audio playback device of claim 1, further comprising a buffering unit which buffers audio data outputted from the path switching unit and transmits the buffered audio data to the audio output unit, wherein the control unit transmits a synchronization control signal to the other mobile communication terminal through the communication interface unit according to a buffering condition of the buffering unit.

6. The audio playback device of claim 1, wherein the audio output unit with a stereo function outputs the audio data to the outside through a left output path of stereo output paths when the transmitted audio data corresponds to a left side, and outputs the audio data to the outside through a right output path of the stereo output paths when the transmitted audio data corresponds to a right side.

7. The audio playback device of claim 1, wherein when an order of division playback of the audio data is input from the input unit, the control unit notifies the other mobile communication terminal through the communication interface unit that the control unit is a main terminal.

8. An audio playback device of a mobile communication terminal, comprising:

a control unit which recognizes the relative location of the mobile communication terminal corresponding to another mobile communication terminal;

a communication interface unit which receives any one of two divided audio data, i.e., left-side audio data and right-side audio data, which are obtained by decoding and dividing original audio data into two halves by means of the other mobile communication terminal, from a corresponding communication interface unit provided in the other mobile communication terminal; and

an audio output unit outputting the received audio data to the outside.

9. The audio playback device of claim 8, wherein the audio data decoded by the other mobile communication terminal is wirelessly received by a mobile communication unit of the other mobile communication terminal, photographed by a camera unit of the other mobile communication terminal, wirelessly received by a broadcast receiving unit of the other mobile communication terminal, and/or stored in a storing unit of the other mobile communication terminal.

10. The audio playback device of claim 8,

wherein the mobile communication terminal includes a left-side connector and a right-side connector, which are coupled with corresponding connectors provided in another mobile communication terminal,

the communication interface unit performs communication with a corresponding communication interface unit provided in the other mobile communication through the left-side or right-side connector, and

the control unit recognizes the relative location of the mobile communication terminal according to whether a connector coupled with the other mobile communication terminal is a left-side or a right-side connector.

11. The audio playback device of claim 10, wherein the left-side connector is a receptible and the right-side connector is a plug, or the right-side connector is a receptible and the left-side connector is a plug.

12. The audio playback device of claim 8, further comprising a buffering unit which buffers the received audio data and transmits the buffered audio data to the audio output unit, wherein the control unit controls a transmission timing of the buffering unit in response to a synchronization control signal received from the other mobile communication terminal through the communication interface unit.

13. The audio playback device of claim 8, wherein the audio output unit with a stereo function outputs the audio data to the outside through a left output path of stereo output paths when the transmitted audio data corresponds to a left side, and outputs the audio data to the outside through a right output path of the stereo output paths when the transmitted audio data corresponds to a right side.

14. The audio playback device of claim 8, wherein the control unit receives information notifying that the other mobile communication terminal is a main terminal through the communication interface unit, and waits for audio data to be received from the other mobile communication terminal.
