The present invention relates to a broadcast receiving terminal, and more particularly, to an apparatus and method for notifying a digital multimedia broadcasting service available area.

In general, DMB (Digital Multimedia Broadcasting) broadcasting is a broadcasting service that provides various multimedia signals such as voice and video to a fixed, portable, and in-vehicle receiver. On the go, personal digital assistants (PDAs) and car terminals provide high-quality and high-definition broadcasting of compact discs (CDs) and digital video discs (DVDs).

In other words, the broadcast receiving terminal is provided with a function of not only a call function but also a digital multimedia broadcasting where the user desires. Therefore, the number of broadcast receiving terminals which provide various functions as described above with a single mobile phone is increasing.

However, if the conventional broadcast receiving terminal wants to receive the digital multimedia broadcasting outside the service area (DMB Out-of-Service), there is no digital multimedia broadcasting signal (DMB Signal), so the digital multimedia broadcasting cannot be viewed. In other words, it is impossible to watch digital multimedia broadcasting without moving the location, but the user has to check the service availability area every time the location is moved.

In addition, even if the user moves out of the service area (Out-of-Service) to the service area (In-Service) does not inform that the service area has a problem that the user continues to try to receive the broadcast efficiency is inferior.

SUMMARY OF THE INVENTION An object of the present invention is to periodically search for a digital multimedia broadcasting signal and indicate whether a service area is displayed on a broadcast receiving terminal so that a user can minimize unnecessary broadcast reception attempts.

In order to achieve the above object, a service area notification device of a broadcast receiving terminal according to the present invention includes a receiving unit for receiving a broadcast signal from a base station; A display unit which displays whether or not a broadcast signal can be received; When the reception of the broadcast signal of the terminal is impossible, the broadcast output option is set according to the user's selection, and when the reception of the broadcast signal is possible, the controller is configured to perform the selected option.

In order to achieve the above object, a service area notification method of a broadcast receiving terminal according to the present invention comprises the steps of: determining whether a broadcast signal can be received from a base station; Setting broadcast output options according to a user's selection when it is impossible to receive a broadcast signal; When the broadcast signal can be received, the process includes performing the selected option.

Hereinafter, the preferred embodiment of the present invention will be described.

The present invention provides a service area notification apparatus and method for a broadcast receiving terminal that can maximize user convenience by minimizing unnecessary broadcast reception attempts by displaying a digital multimedia broadcasting service area on a broadcast receiving terminal.

1 is a block diagram schematically showing a service area notification device of a broadcast receiving terminal according to the present invention.

As shown in FIG. 1, the service area notification device of the broadcast receiving terminal according to the present invention communicates a voice or data with a base station under the control of the control unit 40, which controls the first half of the mobile communication terminal. RF communication receiver 10 for performing communication, DMB RF receiver 20 for receiving a signal of a digital multimedia broadcasting (DMB) base station, and a key for inputting numeric keys, character keys, and function keys through keypad keys. Satellite communication with the input unit 30, the voice processing unit 61 for processing the voice input and output through the microphone or speaker, the IrDA / BT transmitting and receiving unit 63 for transmitting and receiving data through infrared or Bluetooth as a short-range communication means, GPS transmission / reception unit 64 for transmitting and receiving data through GPS as a means, a screen display unit 65 for displaying on a screen such as an LCD, and a memory unit 50 for storing various types of information on the terminal.

The control unit 40 determines whether the input / output control unit 41 controls a pressed key through a key input unit such as a keypad, and whether the pressed key matches the key mapping information for each file type, or whether the pressed time is short or short within a predetermined time. In the case of a key matched with the data determination unit 42 and the determination, a predetermined number of recently executed files are output from a file type corresponding to a key pressed according to the request in the form of a general pop-up or an OSD pop-up screen, or a file It is composed of a data processor 43 for filtering only files matching the type in real time and outputting them on the screen.

2 is a flowchart illustrating an example of a service area notification method of a broadcast receiving terminal according to the present invention.

For convenience of understanding, it is assumed that a user moves out of a service area while receiving a digital multimedia broadcast from a service area (In-Service) to a broadcast receiving terminal.

First, the broadcast receiving terminal located outside the service area determines whether the digital multimedia broadcasting signal has not been transmitted for a predetermined time (S10). If the broadcast signal has not been transmitted for the predetermined time, the terminal screen displays the digital multimedia service restriction area (S12), and then enters the service area and inquires whether the service area is displayed (S14).

If it is selected in the query process (S14) to indicate whether the service area is available, the terminal switches to the standby screen so that the user can perform another phone operation (S16), and the DMB RF receiver 20 periodically digital multimedia The DMB signal is searched for (S18).

This search process S18 is repeated repeatedly until the digital multimedia signal is successfully acquired. Subsequently, if the digital multimedia signal has been successfully acquired, the user is informed of the signal acquisition by silence, vibration, sound, etc. according to the user's setting (S22). At the same time, an icon indicating that the digital multimedia broadcasting service area has been entered is displayed on the standby screen of the terminal (S24), and it is queried whether to continue watching the digital multimedia broadcasting (S26). Thereafter, if the user selects to continue watching the broadcast, the digital multimedia broadcast is output on the standby screen of the terminal to continue watching (S28). On the other hand, if the user chooses not to continue to watch the broadcast in the query process S26, the digital multimedia broadcasting ends (S32).

In addition, if it is selected that the service availability area is not displayed in the query process (S14), the terminal does not switch to the standby screen and immediately terminates the digital multimedia broadcasting (S30).

For convenience of explanation, the above description is made when moving out of the service area in the digital multimedia broadcasting service area by way of example, but the same applies when moving into the service area outside the broadcasting service area, which is obvious to those skilled in the art.

As described above, the present invention has an effect of maximizing user convenience by minimizing unnecessary broadcast reception attempts by indicating whether a digital multimedia broadcasting service area is displayed on a broadcast receiving terminal.

And, the preceding embodiments in the present invention are not limited to the claims by way of example only, various alternatives, modifications and changes will be apparent to those skilled in the art.
