The present invention relates to a terminal capable of a digital multimedia broadcasting service, and in particular, a digital multimedia capable of simultaneously providing a broadcast service and a call service that allows a user to easily use simultaneous services while changing each service as desired during a call service and a broadcast service. A screen display method of a broadcast terminal.

In general, digital broadcasting refers to a broadcasting service that provides a user with high quality, high sound quality, and higher service in place of a conventional analog broadcasting. Recently, with the development of digital broadcasting technology and mobile communication technology, interest in digital broadcasting service for allowing digital broadcasting to be watched on the go has increased. In particular, interest in digital multimedia broadcasting (DMB) services using mobile communication terminals is increasing. The digital multimedia broadcasting refers to a broadcasting service that enables a user to watch various multimedia broadcasting in a multi-channel on the go through a personal portable receiver or a vehicle receiver equipped with an omnidirectional receiving antenna.

Meanwhile, the third generation mobile communication system developed for the purpose of multimedia transmission has differentiation from many existing systems such as high-definition image service and fast data rate. Accordingly, the screen control method of the terminal, which is an example of the development of multimedia technology, is also being developed to enable sharing of the foreground process and the background process on one screen. Among them, the foreground process refers to a process of controlling a high priority application to be executed, and the background process is a process of allowing a low priority application to be executed only when a high priority application is not executed.

Therefore, the terminal screen is composed of a foreground screen executed by the user and a background screen which is not executed by the user but continues to be executed inside the terminal. However, in the conventional display control scheme, when a broadcast service having a lower priority is received, a broadcast that is being played back is interrupted when an incoming call with a high priority comes. In addition, there is a problem that the conventional display control method is not suitable for processing simultaneous services in the digital multimedia broadcasting terminal.

 On the other hand, the current digital multimedia broadcasting terminal provides one screen for the service being performed, so if another service is added in the middle, the service can be started only when the service is stopped.

As described above, since a terminal capable of receiving a digital multimedia broadcasting can only provide a single service at present, if a user is using a broadcasting service and another service, for example, a call service, the currently watching broadcasting service is stopped. Only afterwards will the calling service be available. In addition, when the user wants to use the call service while receiving the broadcast service, the user must first terminate the broadcast service currently being viewed. As such, the conventional digital multimedia broadcasting terminal has no method of simultaneously providing other services during a broadcast service. In addition, in the existing screen display method, only one service is displayed on the screen, and it is difficult to efficiently display images of each service.

Therefore, in the present invention, when a terminal capable of receiving digital multimedia broadcasting needs to simultaneously provide a broadcast service and a call service, a digital multimedia broadcast capable of simultaneously providing a broadcast service and a call service that can efficiently display images of each service on a screen A method of displaying a screen of a terminal is provided.

Another object of the present invention is a screen display of a digital multimedia broadcasting terminal capable of simultaneously providing a broadcast service and a call service for displaying each service screen in various ways so that a user can easily use each service in a mobile phone terminal. In providing a method.

According to an aspect of the present invention, there is provided a screen display method of a digital multimedia broadcasting terminal capable of simultaneously providing a broadcast service and a call service, the method comprising: determining whether a call is received while performing the broadcast service mode, Displaying a message asking whether to maintain the broadcast service mode; and if maintaining a broadcast service mode is selected on the message, performing the call service mode while maintaining the broadcast service mode, and displaying an image of each service. And displaying on the sub-screens respectively.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

The present invention implements a function for providing a simultaneous service in a terminal capable of receiving digital multimedia broadcasting. To this end, the present invention is characterized in that when the user is using any one service, when another service is provided, the image of the other service is displayed on the reference screen determined by the user's selection of the main screen and the sub-screen . In addition, the screen of the terminal to which the present invention is applied is divided into a main screen and a sub-screen by applying a picture in picture (PIP) method.

The screen display method as described above prevents overlapping images of each service during a simultaneous service, and allows a user to simultaneously view images of a service divided and displayed on a main screen and a sub-screen. In addition, the present invention displays a call service screen while maintaining a broadcast service connection, thereby enabling a user to use a new call service without interruption of viewing a broadcast service being used.

Prior to describing the present invention, the simultaneous service used in the present invention will be briefly described. Concurrent service means that the terminal receives another service at the same time without interrupting any service. In particular, the simultaneous service in the present invention refers to a case in which a call service can also be used while the user uses the broadcast service.

In order to look at the components and operation of the terminal implemented such a function will be described with reference to Figure 1 which is an internal block diagram of a digital multimedia broadcasting terminal according to an embodiment of the present invention.

Referring to FIG. 1, first, the digital broadcast receiver 110 receives digital broadcast data through an antenna and outputs the digital broadcast data to the demodulator 120. The demodulator 120 demodulates the digital broadcast data and outputs the demodulated data to the multimedia unit 140.

The multimedia unit 140 functions as a control unit during digital broadcasting, and parses digital broadcast data transmitted from the digital broadcasting receiver 110 through the demodulator 120 into an audio signal and a video signal, and displays the display unit 130. ) And to the audio processor 150.

The display unit 130 receives and displays the display data of the key input data input from the key input unit 160 under the control of the controller 170, or visually knows the state in setting or driving a function required by the user. To help. In addition, the display unit 130 according to the present invention divides and displays each service on the main screen and the sub-screen during simultaneous service under the control of the controller 170. At this time, the sub-screen on the display unit 130 is configured to adjust the size or move the position using the key input unit 160. Accordingly, the user can configure the screen displayed on the display unit 130 of the digital multimedia broadcasting terminal according to his or her taste.

On the other hand, when displaying the simultaneous service on the main screen and the sub-screen, the terminal uses a picture in picture (PIP) method to display the image of the broadcast service and call service on one display unit 130. The PIP method applied to display the screen is a screen display method divided into a main screen and a sub screen, and a method of displaying a sub screen relatively smaller than the main screen. Therefore, when using the call service while the broadcast screen is displayed on the main screen, a sub-screen is generated on the terminal screen to simultaneously view two services.

For example, if there is a call reception while the main screen is displayed, when the call key is pressed for call connection, the video of the call service is displayed on the main screen and the video of the broadcast service is displayed on the sub screen. do. In addition, when a video of the call service is displayed on the main screen and a video of the broadcast service is displayed on the sub screen, when a predetermined key for main / sub screen conversion is pressed, the broadcast service video is displayed on the main screen and the call service video is simultaneously displayed. It is small on the subscreen. As such, the method of displaying the broadcast service screen and the call service screen in order to provide simultaneous services is not limited to the above description and various modifications are possible.

The audio processor 150 is connected to the microphone MIC and the speaker SPK, converts the audio signal transmitted from the multimedia unit 140, outputs the audio signal through the speaker SPK, and receives the audio from the microphone MIC. The signal is converted into data and transmitted to the multimedia unit 140. The audio processor 150 to which the present invention is applied stops the output of the audio signal according to the broadcast service mode when the call is connected under the control of the controller 170, and instead outputs the audio signal according to the call service mode. .

The key input unit 160 outputs its own key input data according to the input of each key provided as a device for interfacing with the user, and the key input data output from the key input unit 160 is applied to the controller 170. As a result, it is detected that the key input data becomes the key input data according to the key input, and according to the result, the controller 170 performs a corresponding operation. For example, the key input unit 160 may include up, down, left, and right arrow keys that can move the position with respect to the sub-screen displayed on the screen on the display unit 130 as described above.

The memory 180 stores information related to overall functions of the digital multimedia broadcasting receiving terminal and at the same time, information related to providing a broadcast service. In addition, the memory 180 stores the audio and video data parsed by the multimedia unit 140 under the control of the controller 170 according to an embodiment of the present invention.

The wireless unit 190 transmits / receives an RF signal with the base station through the antenna ANT under the control of the controller 170.

The controller 170 performs processing and control for various functions including screen processing between a broadcast service and a call service during simultaneous service according to the present invention, as well as normal telephone call, data communication, and wireless Internet connection. In addition, according to the present invention, the controller 170 sets a partition as a base frame for the sub-screen displayed on the display 130, and displays a function that can be edited for the sub-screen on the display 130.

In detail, the controller 170 generates a sub-screen when the call service is added while displaying the broadcast service screen, so that the call service is displayed on the main screen and the broadcast service is displayed on the generated sub-screen. In particular, according to an embodiment of the present invention, the control unit 170 provides detailed functions such as a resizing function, a position shifting function, a subscreen deleting function, a main / subscreen changing function, and the like so that a user can easily edit the subscreen. can do.

 Hereinafter, a process for displaying a simultaneous service on the display unit of the digital multimedia broadcasting terminal configured as described above will be described with reference to FIGS. 2 and 5. 2 is a diagram illustrating a control flow for providing a call service during a broadcast service according to an embodiment of the present invention, and FIG. 5 is a diagram for explaining a screen editing function for a sub screen according to an embodiment of the present invention.

First, when the broadcast service mode is selected by the user, the controller 170 displays the broadcast service on the main screen in step 200. In the state as shown in FIG. 3 (a) of providing a broadcast service screen as described above, the controller 170 determines whether there is a call reception in step 205. If the call is received, the controller 170 proceeds to step 210 and displays a message asking whether to maintain the broadcast service. Subsequently, the controller 170 determines whether broadcast maintenance is selected in step 215. If broadcast maintenance is selected, the controller 170 proceeds to step 220, changes the main screen and simultaneously generates a sub-screen. That is, the controller 170 changes the broadcast service displayed on the main screen to the call service as shown in FIG. 3 (b) and simultaneously generates a sub screen to display the broadcast service on the sub screen. At this time, it is preferable that the output of the audio signal of the broadcast service is stopped and only the audio signal of the call service is output at the time when the call service is connected to simultaneously provide the broadcast service and the call service. In the above description, a case in which a service added by setting the main screen as the reference screen is displayed on the main screen is described as an example. Alternatively, the added service may be displayed on the sub screen while maintaining the service displayed on the main screen. It may be.

Unlike the above, when the broadcast maintenance is not selected in step 215, the controller 170 determines whether the broadcast termination is selected in step 225. If it is determined that broadcast termination is selected, the controller 170 proceeds to step 230 and ends the broadcast service and changes the main screen. That is, as shown in FIG. 4 (a), the broadcasting service displayed on the main screen ends, and instead, the call service screen according to the call reception is displayed as shown in FIG. 4 (b). Then, the controller 170 determines whether the call service is terminated by the user or the counterpart in step 235, and when the call service is terminated, the controller 170 ends the above-described operation.

Meanwhile, the control unit 170 proceeds to step 500 of FIG. 5 after step 220, and the symbol A is used to indicate that steps 220 and 500 are connected to FIGS. 2 and 5. Accordingly, as shown in FIG. 3B, when the call service screen and the broadcast service screen are simultaneously displayed, the controller 170 determines whether there is a sub-screen editing menu selection in step 500 of FIG. 5. Accordingly, when the control unit 170 enters the mode for editing the subscreen in step 500, as shown in FIG. 6A, a submenu for editing the subscreen is popped up. This service menu is displayed on the display unit 130 so that the user can edit the sub-screen. Sub-menus for such sub-screens include menus such as position movement, sub-screen size adjustment, sub-screen deletion, and main / sub-screen conversion.

As shown in FIG. 6A, the controller 170 determines whether the position movement is selected among the submenus in step 510. If the position shift is selected, the controller 170 proceeds to step 515 to perform the position shift of the sub-screen as shown in FIG. 6 (b). That is, the position movement menu enables the user to move the position of the sub screen displayed on the display unit 130 up, down, left, and right. In contrast, when the position shift menu is not selected, the controller 170 determines whether the sub-screen size adjustment is selected in step 520, and if the sub-screen size control is selected, the control unit 170 proceeds to step 525 to perform the sub-screen size adjustment. That is, the sub-screen size adjustment menu allows the user to increase or decrease the size of the sub-screen displayed on the display unit 130 as shown in FIG. 7 (a).

In contrast, when the sub-screen size adjustment menu is not selected, the controller 170 proceeds to step 530 to determine whether or not to delete the sub-screen. If sub-screen deletion is selected, the controller 170 proceeds to step 535 to delete the sub-screen. That is, the sub-screen deletion menu prevents the sub-screen from being displayed on the display unit 130 so that only the main screen is displayed on the display unit 130. At this time, even if the sub-screen is deleted while the call service is displayed on the main screen and the broadcast service is displayed on the sub-screen, the broadcast service is running in the background without being displayed on the screen. As such, the sub-screen delete menu is a menu for releasing a simultaneous screen divided into a main screen and a sub-screen, and displays only the main screen on the display unit 130. Accordingly, since one service screen is displayed on the display unit 130, by using a predetermined key assigned to each service to view another service screen, the user can toggle the broadcast service screen and the call service screen. Make sure

If the sub-screen delete menu is not selected, the controller 170 proceeds to step 540 and determines whether main / sub-screen conversion is selected. If main / sub picture switching is selected, the controller 170 proceeds to step 545 to convert main / sub picture. That is, the service displayed on the main screen and the service displayed on the subscreen are displayed interchangeably. For example, as shown in FIG. 8 (a), when the main / sub picture conversion menu is selected while the call service is displayed on the main screen and the broadcast service is displayed on the sub screen, the call screen is shown in FIG. 8 (b). As shown, the broadcast service is displayed on the main screen, and the call service is displayed on the sub-screen.

On the other hand, in the case of terminating any one service such as terminating the broadcast service or terminating the call service during the simultaneous service, it is preferable that only the corresponding service currently being displayed on the entire screen on the display unit 130 and the sub-screen are deleted.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. In the above-described embodiment of the present invention, the display method of the simultaneous service has been described using the PIP method, but the display method of the simultaneous service may be variously modified. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below but also by the equivalents of the claims.

According to the present invention as described above, the terminal of the digital multimedia broadcasting reception is displayed on the main screen and the sub-screen for each image of the service input at the same time to prevent overlapping the images appearing on the screen of the terminal based on the current screen Therefore, the video of each service is displayed on the screen in a divided manner so that the user can efficiently use the simultaneous service. In addition, by providing an editing function for the divided screen, there is an advantage that the user can directly edit and display the display method of the simultaneous service to meet the user's special needs.
