The present invention relates to a mobile communication terminal having a digital broadcasting reception function, and more particularly, when a specific key is pressed during digital broadcasting reception, a digital connection of a mobile communication terminal configured to perform a telephone connection to a broadcasting station performing a corresponding broadcast. The present invention relates to a telephone connection system and a method thereof during broadcast reception.

Digital Audio Broadcasting (DAB) technology digitally modulates audio signals and provides them to fixed, portable, and vehicle receivers over the air. Receiving antenna is a word that refers to a system using omnidirectional antennas. These include DAB, phase DAB and stop wave AM band digital radios.

On the other hand, digital multimedia broadcasting (hereinafter referred to as "DMB") is a broadcasting service that provides various multimedia signals such as audio and video to a fixed, portable, and vehicle receiver in a digital manner. There are systems A, Dh, and E provided. System A follows the European Digital Broadcasting Standard (OFDM: Orthogonal Frequency Division Multiplexing) of digital satellite broadcasting and terrestrial DMB, and system Dh is based on terrestrial DMB but adopts a hybrid scheme to accommodate satellite DMB. The code division multiple access (CDM) scheme is almost identical to the division multiple access (CDMA).

Terrestrial digital multimedia broadcasting (DMB) has already been allocated to channel 12 of the ultra-high frequency (VHF) band corresponding to 174MHz to 216MHz of television channels 7 to 13. Channel 12 is further divided into three frequency blocks (multiplexers), which can allocate a bandwidth of 1.54 Mbps per block. With this bandwidth, one video channel and three audio and data channels can be accommodated. Thus, a bandwidth of one channel (VHF No. 12) of an analog TV can accommodate three video channels and nine audio and data channels. As such, terrestrial DMB can use digital technology to significantly increase frequency efficiency.

Terrestrial DMB, which conforms to the European standard 'Eureka-147', is a strong orthogonal receiver that is resistant to the effects of multipath fading, which is a characteristic of the mobile transmission channel, to provide various services stably even when moving. A transmission scheme called Orthogonal Frequency Division Mutiplexing (OFDM) is used. In addition, the frequency efficiency is high by applying a compression method called MPEG 4, which has a higher compression efficiency than MPEG 2 of terrestrial digital television.

Satellite DMB, on the other hand, is serviced in the 2.630 to 2.655 kHz band, which is a much higher frequency band than terrestrial waves (UHF). If the terrestrial DMB covers the metropolitan area by launching radio waves from the Gwanaksan transmitting station, the satellite DMB is capable of broadcasting nationwide at once by launching radio waves toward the Korean Peninsula from satellites outside the atmosphere. First of all, the satellite-based service uses Ku-band frequency (13.824) to provide various contents such as news, music videos, sports, movies, dramas, songs, jazz, foreign languages, securities, transportation, and weather. ~ 13.883㎓) to the satellite. The satellite then transmits it to the terrestrial terminal via the S-band (2.630-2.655 GHz) allocated for DMB. If it is not possible to receive satellite signals directly, a terrestrial repeater called 'Gap Filler' relays broadcast signals, allowing the user to use the DMB service anytime and anywhere.

The above-mentioned Digital Lion Broadcasting (DAB) service was launched in 1995 in the UK and China, and is currently being developed and invested in facilities for the commercialization of Digital Multimedia Broadcasting (DMB) worldwide.

Such digital multimedia broadcasting enables broadcast reception in a mobile communication terminal, and a user can watch a high quality broadcast using the mobile communication terminal. Accordingly, an increase in broadcast content using DMB or DAB is expected, and a user may purchase a product or participate in a broadcast in real time by performing a telephone connection to a DMB or DAB broadcast host such as home shopping or radio broadcasting that is performed live. .

However, in order to participate in such a DMB or DAB broadcast that is broadcast in real time, the user must know the telephone connection number of the broadcast in advance, and there is a cumbersome problem of inputting the corresponding telephone number for the telephone connection for participation.

Accordingly, the present invention is to solve the above-mentioned problems of the prior art, and if the transmission includes the phone number information that can access the program among the digital multimedia broadcasting provided in real time, the mobile communication terminal is broadcast during the reception of the broadcast; It provides a telephone connection system and method for receiving a digital broadcast of a mobile communication terminal that automatically switches to a corresponding telephone number when a user presses a specific key by storing the telephone number included in the mobile phone and assigning it to a specific key. For that purpose.

A system of the present invention for achieving the above object comprises a broadcast provider system for generating a digital broadcast signal including additional information having broadcast content information and to transmit it to a digital broadcast network; And a mobile communication terminal for storing the additional information and allocating a telephone number for connection with a broadcaster performing the broadcast among the additional information to a specific key as a speed dial key.

The mobile communication terminal includes: a digital broadcasting processing unit for receiving and outputting a digital broadcasting signal transmitted by the broadcasting provider system using the digital broadcasting network; A storage unit for storing additional information output from the digital broadcasting processor; And a controller for allocating a specific key as a speed dial key to dial the phone number when the phone number is included in the additional information.

According to an aspect of the present invention, there is provided a viewer participation method in digital broadcasting, comprising: transmitting a digital broadcast signal including additional information in a digital broadcast signal for digital broadcasting; A digital broadcast signal reproduction process of extracting and storing the additional information receiving the digital broadcast signal and reproducing the digital broadcast signal as an image and an audio signal; And a shortcut dial key assignment step of allocating a specific key to a shortcut dial key to dial a telephone number among additional information output during the digital broadcast signal reproduction process.

The present invention is also characterized in that it further comprises a call connection process for performing a call connection to the assigned telephone number when the speed dial key is pressed after the speed dial key assignment process.

The additional information may include product information for home shopping, price information, and connection telephone number information with the home shopping company for ordering.

The additional information may also be a connection telephone number of a real-time digital broadcaster that the viewer or listener wants to participate in.
