Abstract

A DMB(Digital Multimedia Broadcasting) receiver having a touch screen and a DMB control method thereof are provided to enable a user to enjoy broadcast contents according to the preference of a user by easily combining broadcast contents only with a simple touch input using a touch screen. A control part controls a display part and an audio processing part and regenerates broadcast contents equivalent to selected channels on their respective independent areas(S310). While regenerating the broadcast contents, the control part judges whether a touch input is detected for a specific area among the independent areas(S320). If so, the control part confirms whether a shift for the touched area is generated(S330). If the touched area is shifted, the control part detects coordinates when the touch input stops(S340). Then the control part judges whether the detected coordinates belong to the other independent area(S350). If so, the control part combines the broadcast contents of the touched area with the broadcast contents of the other independent area containing the detected coordinates(S360). Then the control part outputs the combined broadcast contents through the display part and the audio processing part(S370).

Referring to FIG. 2 and FIG. 1 described above, the controller 140 controls the display unit 151 and the audio processor 160 to reproduce broadcast content corresponding to a channel selected in each independent region (S210). During the reproduction of broadcast content, the controller 140 determines whether there is a combination request for combining broadcast content output from an independent region (S220). For example, the combination request signal is a signal for sequentially touching each broadcast content.

If there is a combination request, the controller 140 combines the broadcast contents output from the independent region (S230) and outputs the combined broadcast contents through the display unit 151 and the audio processor 160 (S240). At this time, it is preferable to control the display unit 151 of the control unit 140 to display the combined video signal of the content on the full screen. For example, when a combination request signal is input to an area for playing video broadcast content and an area for playing audio broadcast content among independent areas, the controller 140 simultaneously controls the video signal of the video broadcast content and the audio signal of the audio broadcast content. Output For another example, when a combination request signal is input to areas that play different video broadcasting contents among independent areas, the controller 140 simultaneously outputs a selected video signal and an audio signal according to a selection signal input to each area. do. In this case, the selection signal is one of an audio selection signal for selecting an audio signal and a selection signal for selecting an image signal. For example, the audio selection signal is a set letter 'A' or 'a' input signal representing audio in an independent area displayed on the touch screen. The video selection signal is a set letter 'V' or 'v' input signal representing an image in an independent area displayed on the touch screen.

Referring to the screen examples of S210 to S240, the video broadcast content 411 and the audio broadcast content 415 are reproduced as shown at 410 in FIG.

During playback of the broadcast content, the controller 140 determines whether a touch input is detected in a specific region among independent regions (S320). When a touch input is detected in a specific area, the controller 140 checks whether there is a movement of the touch area where the touch input is detected (S330). If there is a movement, the controller 140 detects the coordinates of the time point at which the touch input ends (S340). The controller 140 determines whether the detected coordinates are included in another independent area (S350). If included in another independent area, the controller 140 combines the broadcast content of the area where the touch is detected and the area including the coordinates of the point at which the touch input ends (S360), and displays the combined broadcast content with the display unit 151. It outputs through the audio processor 160 (S370). In this case, since the combined output process is described above with reference to FIG.

During the reproduction of the combined broadcast signal, the controller 140 determines whether there is an input of the broadcast content separation signal (S380). If there is an input of the broadcast content separation signal, the controller 140 separates the combined broadcast signal and reproduces the broadcast content in each of the independent regions (S390). On the other hand, if there is no movement of the touch area where the touch input is detected in the above-described step S330, the controller 140 performs a corresponding function.
