The multimedia playback of the main terminal 100m and the sub terminal 100s may be controlled by a control signal. There are various methods for reproducing the multimedia by interlocking the main terminal 100m and the sub terminal 100s. A detailed description thereof will be given later with reference to the drawings.

In addition, the mobile terminal 100 according to an embodiment of the present invention can receive and reproduce multimedia in real time. Next, a description will be given of a method of receiving and playing multimedia data in mobile terminals (100 m and 100 s) in real time.

5 is a flowchart illustrating a multimedia playback method of a mobile terminal according to an embodiment of the present invention.

The same multimedia can be received from the main terminal 100m and the sub terminal 100s according to an embodiment of the present invention (S110). In some cases, the main terminal 100m and the sub terminal 100s can receive multimedia in real time via the wireless communication unit 110. [ In particular, when the multimedia is related to the broadcast data, the multimedia can be received through the broadcast receiving module 111. In this case, the multimedia playback may be performed in the main terminal 100m and the sub terminal 100s, respectively. That is, the main terminal 100m and the sub terminal 100s can be separately controlled to reproduce multimedia.

However, according to an embodiment of the present invention, multimedia playback of the sub terminal 100s may be controlled by a control signal generated in the main terminal 100m. When multimedia is reproduced by the above-described method, the main terminal 100m may transmit the control signal to the sub terminal 100s (S120). In this case, the user can extend the size of the screen or the number of speakers using a plurality of mobile terminals.

That is, the sub terminal 100s does not control the multimedia reproduction itself, but controls the multimedia reproduction by the control signal transmitted from the main terminal 100m.

The control signal may be transmitted through a wireless communication network. In particular, the transmission may be performed using a local area network. For example, communication technologies such as Bluetooth, Radio Frequency Identification (RFID), infrared data association (IrDA), ultra wideband (UWB), and ZigBee are used for transmission of the multimedia signals and control signals. Can be used.

The sub-terminal 100s receives the control signal transmitted using the communication technology described above (S130). The sub terminal 100s receiving the control signal reproduces the multimedia in cooperation with the main terminal 100m (S140). The multimedia playback of the main terminal 100m and the sub terminal 100s may be controlled by a control signal. There are various methods for reproducing the multimedia by interlocking the main terminal 100m and the sub terminal 100s. A detailed description thereof will be given later with reference to the drawings.

Hereinafter, a method of reproducing multimedia in the method of FIG. 4 or 5 will be described in more detail.

First, a method of expanding a displayed image using the main terminal 100m and the sub terminal 100s during multimedia reproduction will be described.

6 is a diagram for explaining a multimedia playback method of a mobile terminal according to an embodiment of the present invention.

As shown, both the main terminal m and the sub terminal 100s can reproduce multimedia. The main terminal 100m and the sub-terminals can independently play multimedia.

However, in the main terminal 100m and the sub terminal 100, the main terminal 100m and the sub terminal 100s may be interlocked to reproduce multimedia or separately play multimedia according to the location of each terminal. The location of each terminal can be determined according to the radio signal strength of the local communication. When a magnet (not shown) is provided on the upper, lower, left, and right sides of each of the terminals 100m and 100s, the position and distance of each of the terminals 100m and 100s can be grasped through the magnet.

7 is a diagram for explaining a multimedia playback method of a mobile terminal according to an embodiment of the present invention.

As shown in the figure, the screen reproduced in the main terminal 100m is interlocked and reproduced in the sub terminal 100s. That is, the screen to be reproduced is expanded from one terminal to three terminals. As described above, by playing the same multimedia on both the main terminal 100m and the sub terminal 100s, there is an effect of expanding the playback screen. According to the illustration, the arrangement of the terminals is simply side-by-side, but the invention is not so limited. For example, although not shown, the sub terminal 100s can be located anywhere on the main terminal 100m, and can reproduce the multimedia along with the main terminal 100. [

The multimedia to be reproduced may be stored in the main terminal 100m or received from both the main terminal 100m and the sub terminal 100s through a broadcaster or the like.

When the multimedia reproduced from the main terminal 100m is reproduced together with the sub terminal 100s, the multimedia reproduction module 181m of the main terminal 100m separates one region of the reproduced image, Is enlarged and displayed. For example, a left one-third of the images displayed in the main terminal 100m (shown in FIG. 6) are separated and displayed in an enlarged manner to fit the screen size of the main terminal 100m (shown in FIG. 7).

In addition, according to an embodiment of the present invention, an image corresponding to one area can be extracted from the reproduction screen of the main terminal 100m and reproduced from the sub terminal 100s.

In this case, the width of the extracted image may be automatically determined according to the number of terminals. For example, when three multimedia terminals are reproduced (one main terminal and two sub terminals), an image reproduced on the main terminal screen is divided into three, and one image is output through the main terminal 100m screen So that another video is outputted through the screen of the first sub terminal 100s and the other video is outputted through the screen of the second sub terminal 100s.

In addition, the width of the extracted image may be determined by user selection. That is, the user of the main terminal 100m can operate the operation unit 130m to determine the image to be reproduced in the main terminal 100m and the image to be reproduced in the sub terminal 100s. In particular, when the operation unit 130m of the main terminal 100m is configured as a touch screen having a mutual layer structure with the display module 152m, the image can be extracted through the touch of the screen. Fig. 8 shows such an example.

The user of the main terminal 100m transmits a video data including the drawn area to the sub terminal 100s by one area (a portion drawn as a rectangle) on the screen where the video of the main terminal 100m is displayed .

Then, the sub terminal 100s can receive the image data and reproduce the image corresponding to the transmitted area according to the screen size. The drawn area is enlarged and displayed on the sub terminal 100s. In this case, the display screen can be moved using the scroll key provided on the operation unit 130. [ Of course, only the above-described drawn area can be displayed on the screen of the sub terminal 100s. The enlargement of the image in the sub terminal 100s can be controlled by the control signal generated in the main terminal 100m.

Also, according to an embodiment of the present invention, the transmission can be performed by dragging the drawn area in the direction in which the sub terminal 100s is located.

Meanwhile, according to an embodiment of the present invention, a screen related to execution of a specific application executed in the main terminal 100m may be displayed along with the sub terminal 100s. An example of such is shown in Fig.

FIG. 9 is a diagram illustrating a state of displaying a screen related to music playback in a mobile terminal according to an embodiment of the present invention.

As shown, screens related to music playback in the main terminal 100m and the sub terminal 100s are divided and displayed, respectively. In the illustrated sub terminal 100s, when the media player is operated, the album information is displayed separately.

The width of the divided area may be determined automatically without a user's operation, or may be determined by a user's operation.

Meanwhile, according to an embodiment of the present invention, the sound reproduced using the main terminal 100m and the sub terminal 100s may be extended.

Next, a method of expanding the sound output by using the main terminal 100m and the sub terminal 100s during multimedia reproduction will be described.

When multimedia including a multi-channel encoded audio signal is reproduced, the number of channels output may vary according to the number of speakers provided in the terminal. For example, an audio signal encoded in multiple channels can be converted into a mono signal and outputted when the signal is output from a terminal having one speaker. In addition, the multi-channel encoded audio signal may be converted into a stereo signal and output when output from a terminal having two speakers.

However, when the multi-channel encoded signal is output as a mono signal or a stereo signal as described above, the spatial sensitivity of the original signal may deteriorate. In this case, when the audio signal is output using the main terminal 100m and the sub terminal 100s together, the sense of space can be further saved.

10 is a diagram illustrating a method of extending a sound output using a mobile terminal according to an embodiment of the present invention.

FIG. 10 shows a state in which audio is output using a plurality of mobile terminals (one main terminal and four sub terminals). For example, a speaker provided in the main terminal 100m may output an audio signal corresponding to a center channel, and a sub terminal located on the left side of the user may output an audio signal corresponding to a front-left channel and a rear- Can be output. Also, the sub-terminal located on the right side of the user can output audio signals corresponding to the front-right channel and the rear-right channel, respectively. Of course, the control of the audio signal output may be performed by a control signal generated in the main terminal 100m.

As described above, by outputting audio using a plurality of mobile terminals (one main terminal and four sub terminals), it is possible to output a signal close to the original sound (a signal encoded with multiple channels).

The expansion and / or the sound of the reproduced image can be expanded by using the above-described multimedia reproduction method.

The mobile terminal capable of reproducing the multimedia as described above can be applied to all or some of the embodiments so that various modifications can be made to the embodiments and methods of the embodiments described above. Or may be selectively combined.
