The present invention relates to a remote control apparatus and a method for guiding digital broadcast program information of a digital broadcast receiver, and more particularly, to receive broadcast program guide information from a digital broadcast receiver (ie, a DMB receiver) and to guide broadcast program information to a user. It relates to a remote control device and a method thereof.

Digital Multimedia Broadcasting (DMB) refers to a broadcasting service that allows a user to watch various multimedia broadcasts through a plurality of channels on the go through a personal portable receiver or a vehicle receiver equipped with an omnidirectional receiving antenna.

1 is a diagram illustrating a system configuration for implementing a digital broadcast service.

Referring to FIG. 1, a system for implementing a digital broadcasting service includes a data transmission center 10, a satellite 20, receivers (eg, a mobile communication terminal 30, a vehicle receiver 40, and a home receiver 50). ), Etc.).

The data transmission center 10 compresses and modulates digital-multimedia-broadcasting data (eg, image, audio, and data signals) and transmits the same to the satellite 20.

The satellite 20 receives the signal transmitted from the data transmission center 10, amplifies it, converts the frequency, and retransmits it to the ground.

The receivers 30, 40, and 50 receive and demodulate the signals retransmitted from the satellite 20, decompress them, and convert them into original signals.

One of the advantages of such a digital broadcasting service is that channel efficiency is much higher than that of an analog broadcasting service. That is, in analog broadcasting, only one program existed on one physical channel. However, in digital broadcasting, several programs can be simultaneously delivered to one physical channel. Therefore, digital broadcasting service can provide quite a lot of programs and provide program information to make it easier for viewers to choose the program they want. For this purpose, EPG (Electronic Program Guide) service is usually provided.

The EPG service is a service that allows a viewer to refer to the program information by providing various program information about the broadcast to the viewer from a broadcasting station (or service operator (SO) of cable broadcasting) that provides the program. For example, the EPG service provides information (eg, digital broadcast program guide data, hereinafter referred to as 'EPG' data) for each program, such as a program title, a broadcast start time and a closing time. Typically such EPG data is provided with a predetermined period or upon change of the EPG data.

Then, the receiving apparatuses 30, 40, and 50 receive the EPG data and store the information therein, and generate digital broadcast program information with the stored EPG data in response to a user's request and provide the same to the user.

In general, when a vehicle digital broadcasting receiver is mounted, it is installed at the front of the vehicle to secure the viewing distance of the vehicle occupant so that they can watch. In such a situation, when the broadcast program information is displayed on the digital broadcast receiver screen using EPG data, a vehicle occupant having a far field of view may be difficult to see or cannot see the digital broadcast program information screen. In this case, the vehicle occupant may operate a desired function by controlling the digital broadcast receiver using a remote controller or the like, but the digital broadcast program information using the EPG data cannot be viewed.

Accordingly, an object of the present invention is to provide a remote control apparatus and method for guiding digital broadcast program information of a digital broadcast receiver regardless of a user's position when receiving a digital multimedia broadcast.

Another object of the present invention is to provide a remote control apparatus and a method for allowing a user to select a desired broadcast by receiving digital broadcast program information even where a screen of a digital broadcast receiver cannot be viewed when receiving a digital multimedia broadcast.

In order to achieve the above object, the present invention provides a digital broadcast program information guide method. Transmitting, by the digital broadcast receiver which prestored the digital broadcast program guide data, the pre-stored digital broadcast program guide data to the remote control device in response to a request for digital broadcast program guide data of the transceiver for remotely controlling the digital broadcast receiver; And displaying, by the remote control apparatus, the transmitted digital broadcast program guide data to guide the digital broadcast program to the user.

In another aspect, the present invention provides a digital broadcast receiver, comprising: a data receiver for receiving digital broadcast data and digital broadcast program guide data, a storage unit for storing the received digital broadcast program guide data, and a remote control for remotely controlling the digital broadcast receiver. A communication module unit for receiving a digital broadcast program guide data request signal from a controller and transmitting the digital broadcast program guide data to the remote controller, controlling an operation of the digital broadcast receiver, and requesting the digital broadcast program guide data request. And a controller for detecting digital broadcast program guide data in the storage and transmitting the detected digital broadcast program guide data to the remote controller through the communication module.

In another aspect, the present invention provides a remote control device for remotely controlling a digital broadcast receiver, the operation of the remote control device being controlled, requesting the digital broadcast receiver for guidance data of a digital broadcast program by a user's operation signal, and the digital broadcast receiver. A control unit for transmitting user selection information about the digital broadcasting program guide data to the digital broadcasting receiver when the digital broadcasting program guide data is transmitted from a receiver, and a digital program guide data request signal and the user selection information under control of the control unit. A transmission and reception unit for transmitting the digital broadcast receiver to the digital broadcast receiver and receiving the digital broadcast program guide data from the digital broadcast receiver, a display unit for displaying the received digital broadcast program guide data, Characterized in that it comprises a user interface for transmitting the operation signal to the control unit.

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.
