The present invention relates to an apparatus and a method for providing a DMB-related service, and more particularly, to provide a DMB-related service using a mobile communication terminal that can provide DMB-related service information to a wireless Internet through a general mobile communication terminal. An apparatus and method are provided.

In general, a digital multimedia broadcasting service (hereinafter, simply referred to as 'DMB') refers to a broadcasting service capable of watching multi-channel multimedia broadcasting anytime and anywhere through a personal portable receiver or a vehicle receiver.

Until now, TV broadcasting service has been targeted to TV receivers installed in homes such as terrestrial, cable TV, and satellite broadcasting. Recently, the satellite broadcasting service provider guarantees the mobility of broadcasting services for vehicles equipped with vehicle antennas. This is only a mobile type of broadcast service.

On the other hand, the DMB service is classified into a satellite DMB service and a terrestrial DMB service, which is characterized as a personal service in terms of serving an individual through a mobile phone, a PDA, a dedicated terminal, or a vehicle terminal.

1 is a schematic configuration diagram of a general satellite DMB service system.

The satellite DMB service system includes a broadcast center 10 for transmitting a signal compressed / multiplexed to broadcast satellites, a satellite system 20 for frequency-converting the signals received from the broadcast center 10, and a satellite system 20 DMB terminal 30 for demodulating the signal transmitted from the terminal to provide broadcast information to the subscriber, and a gap filler 40 to compensate for the shadow area.

The broadcasting center 10 is a Ku band frequency 13.824-13.883 ㎓ ( TDM) and 13.858-13.883 kHz (CDM) to the satellite system 20.

The satellite system 20 converts the TDM and CDM signals transmitted from the broadcasting center 10 to the gap filler 40 and the DMB terminal 30, and transmits the signals to the gap filler 40. Uses the Ku band frequency of 12.214 ~ 12.239 Ku (TDM), and the signal sent to the DMB terminal uses the S band frequency of 2.630 ~ 2.655㎓ (CDM).

In order to directly transmit images and data to subscribers in satellite DMB, satellites, ground control facilities for controlling them, antennas for repeating broadcast signals, and repeaters are required.

Here, the satellite body, unlike the existing satellite broadcasting, the output is very strong in consideration of the miniaturization and mobility of the DMB terminal 30 on the ground, and thus is enlarged to secure sufficient power capacity.

In addition, the DMB terminal 30 demodulates the CDM signal transmitted from the satellite system 20 and the gap filler 40 to output broadcast information to the DMB subscriber.

The DMB terminal 30 can be classified into a fixed type, a vehicle type, and a personal portable terminal. The personal portable is integrated with a mobile phone, and can be linked with a wireless Internet and a public data network. Meanwhile, the DMB terminal 30 provides various functions such as AM / FM / DAB reception, GSM / GPRS mobile phone, portable computer, MP3, and voice recording, information search, and multimedia functions.

Finally, the gap filler 40 receives the satellite TDM signal, converts it into a CDM signal, and transmits the same to the DMB terminal 30. That is, the gap filler 40 complements the shaded area to ensure the reception quality, and it is possible to newly install or utilize a ground repeater for mobile communication. The gap filler 40 is designed to be elastic in consideration of the situation of the receiving area and can be annually supplemented and expanded to buildings, tunnels, downtowns, and outskirts. Can be divided into within 100 ~ 300m, within 1km or 3km.

In particular, in the satellite DMB service system and the terrestrial DMB service system, as described above, the DMB terminal 30 is not only a terminal in which the DMB and mobile communication functions are integrated, but also a terminal having no DMB broadcasting listening function. It will also increase. The emergence of new multimedia devices is expected due to the convergence of existing multimedia devices such as PMPs and game consoles and DMB terminals, and vehicle DMB terminals are also currently planned to be dedicated DMB terminals without mobile communication functions.

However, since these devices do not have a return channel to access the wireless Internet, they do not receive the previously expected communication convergence service, and even users who do not have a DMB terminal may not be able to receive DMB broadcasts while watching other users through DMB terminals. There is also a situation where you want to access the associated content.

Accordingly, there is a need for accessing and using the wireless Internet using a mobile communication terminal of contents associated with the DMB anytime and anywhere regardless of whether the DMB terminal is owned or not.

The present invention has been made to solve the above-described problems, so that DMB-related services can be provided by connecting to the wireless Internet through a general mobile communication terminal, even in the case of a DMB terminal without a return channel, The purpose is to enable the use of telecommunication broadcast convergence services using a mobile communication terminal.

Another object of the present invention is to simply connect the DMB terminal and the mobile communication terminal by wireless to use the corresponding content, to provide a communication broadcasting convergence service easily without complicated procedures and rejection.

Still another object of the present invention is to enable a user who does not own a DMB terminal to receive a communication broadcasting convergence service provided during DMB viewing.

The configuration of the present invention devised to achieve the above object is as follows. The present invention relates to a mobile communication terminal using the DMB-related service by using various DMB-related service information included in a DMB broadcast signal provided to a DMB terminal from a satellite system and a gap filler to provide a DMB-related service through a wireless Internet. An apparatus for providing a signal processing apparatus, comprising: a signal processing unit installed in a DMB terminal to separate DMB related service information from a DMB broadcast signal transmitted from a satellite system or a gap filler, respectively installed in the DMB terminal and the mobile communication terminal and separated from the signal processing unit; The wireless communication unit transmits / receives DMB-related service information to a mobile communication terminal through short-range wireless communication, and accesses an information server that provides DMB-related services through wireless Internet according to the DMB-related service information, and requests DMB-related services. Including wireless internet connection provided to the terminal Characterized in that W is made.

Here, the signal processing unit determines whether there is DMB related service information from the DMB broadcasting signal, and if there is a DMB related service, a service information processing unit which separates the DMB related service information from the DMB broadcasting signal, and displays the DMB related service information. It characterized in that it comprises a service information display unit to confirm that there is DMB-related service information.

The wireless communication unit may use any one of IrDA, Bluetooth, Zigbee, UWB, and WiMedia.

Meanwhile, DMB-related services are provided to a mobile communication terminal by using various DMB-related service information included in a DMB broadcast signal provided to a DMB terminal from a satellite system or a gap filler to provide DMB-related services through a wireless Internet. In the device, if there is DMB-related service information by determining the presence or absence of DMB-related service information in the DMB broadcast signal, the first step of separating the DMB-related service information from the DMB broadcast signal, moving the DMB-related service information separated from the DMB terminal And a third step of requesting a DMB related service from an information server providing a DMB related service by accessing the wireless Internet with the transmitted DMB related service information.

In this case, the first step includes displaying the DMB related service information through an image output unit of the DMB terminal, and the second step uses IrDA, Bluetooth, Zigbee, UWB, or WiMedia. It is characterized by.
