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, and is classified into satellite digital broadcasting and terrestrial digital broadcasting.

Satellite digital broadcasting is mainly intended for mobile services, and is a broadcast capable of watching multi-channel multimedia broadcasting anytime, anywhere through a portable receiver (mobile phone, personal digital assistant) or a vehicle receiver.

Terrestrial digital broadcasting, which is based on DAB (Digital Audio Broadcasting), is a concept of performing multimedia broadcasting for mobile reception using the VH channel 12, which is currently empty, and using TV, radio and data broadcasting using multiple channels. Means a broadcast that transmits a combination of the two. Conventional terrestrial operators operated one analog channel, but digital broadcasters have a concept of operating multiple digital channels, and these services are called ensemble.

In addition, in the terrestrial digital broadcasting, three ensembles can be transmitted in one VHF (Very High Frequency) channel, and one video, two audio, and one channel of data can be provided per ensemble. It is aimed at free broadcasting with the use in mind. Operators include Korean Broadcasting (KBS), Cultural Broadcasting (MBC), SBS (SBS), Digital Skynet, which provides audio channels to CBS, YTN, and Sky Life. Eight companies are preparing for business.

On the other hand, with the increasing number of broadcast programs that viewers can directly participate in, the number of users participating in the digital broadcasting (eg, entertainment, discussions, fundraising, ARS programs, etc.) is increasing. For example, if you want to inquire about the product while watching a home shopping program, you may call the counselor by looking at the phone number displayed in the subtitle.

In addition, since there are various corners in which users can participate according to digital broadcasting programs, users often have a desire to participate in broadcasting more actively.

In the case of the fundraising program as an example, if a user wants to participate in the fundraising while watching a fundraising program on a regular TV, the ARS phone number displayed through the subtitles on the screen is used to call the phone or mobile phone. You can make a call by calling. In addition, even if a user wants to deposit a donation while watching a donation fund using a mobile communication terminal capable of receiving digital broadcasts, the donation is completed by connecting a call to an ARS phone number after finishing watching the broadcast. The donation may be deposited by returning to the digital broadcasting viewing screen.

However, this is inconvenient for the user to manually enter the phone number displayed on the screen, and if you are watching a regular TV, you can enter a phone number while watching the TV screen because you use a separate phone, but the phone function and digital broadcast playback function In the case of a terminal having the same, it was inconvenient to make a call once the user switched from the digital broadcasting viewing mode to the call mode.

In addition, even if the user wants to obtain broadcasting information on a specific program of digital broadcasting, there is a inconvenience that a user must separately search for a corresponding Internet web site to obtain broadcasting information that he / she wants.

Accordingly, an object of the present invention is to provide a two-way digital broadcast service method in which a user can effectively participate in a corresponding program when viewing a digital broadcast program that a viewer can participate through a mobile communication terminal.

Another object of the present invention is to provide a method for easily knowing the information that a user wants to know while watching digital broadcasting through a mobile communication terminal.

In order to achieve the above object, the present invention provides a digital broadcasting service method of a mobile communication terminal capable of receiving digital broadcasting, and receiving and outputting a digital broadcasting signal including U.L. (URL) information of digital broadcasting. Detecting URL information from the received digital broadcast signal, and accessing the web site of the digital broadcasting being output through the detected URL address if the user requests to participate in the digital broadcast.
