First, in the case of a short message, the phone module 120 of the mobile communication terminal 100 receives a short message including start time and end time information of a specific broadcast program and recording reservation information including channel information to the terminal. If so, the recording reservation information is extracted from the short message and transmitted to the recording control unit 114. The recording control unit 114 according to the received recording reservation information, the RF tuner unit 111 and the CDM at the program start time. The chip unit 112 is driven to set the corresponding channel, and reservation recording control is performed by stopping the driving of the RF tuner 111 and the CDM chip unit 112 at the program termination time of the recording reservation information.

When using the PSI / SI, the PSI / SI table transmitted by the broadcasting center 300 through the broadcasting network is received by the DMB module 110. Accordingly, the recording controller 114 records directly from the PSI / SI table. The reservation information is extracted, and reservation recording control according to the recording reservation information is performed in the same manner as in the case of using the short message.

The broadcast program signal recorded in the broadcast program storage unit 115 as described above is output by the multimedia processing unit 113 at the request of the user later, so that the user can watch.

Next, FIG. 3 is a configuration diagram of a DMB reserved recording service server according to an embodiment of the present invention, and illustrates a configuration of a service server for receiving and processing a recording reservation request of a user connected through a wired or wireless Internet.

As shown, the DMB reserved recording service server 200 is connected to the EPG storage unit 210 for storing the electronic program guide data (EPG) provided from the broadcasting center 300, the electronic program guide data through the wired or wireless Internet EPG provider 220 for providing to a user, if a program to be scheduled recording using the electronic program guide data is selected recording reservation processing unit for transmitting the corresponding recording reservation information to the user's mobile communication terminal 100 ( 230, a recording reservation information storage unit 240 for storing the recording reservation information.

The EPG provider 220 allows the user to select a program to reserve recording when the user connects via wired or wireless Internet using the mobile communication terminal 100 or the computer 101 to request a broadcast program reservation recording request. It serves to provide electronic program guide data stored in the EPG storage unit 210.

When the user selects a specific broadcast program and requests a scheduled recording through the electronic program guide data provided by the EPG provider 220, the recording reservation processor 230 requests a start time, an end time, and a channel of the corresponding broadcast program. The recording reservation information including the information is transmitted to the mobile communication terminal 100 of the user.

The recording reservation information may be transmitted to the mobile communication terminal 100 as a PSI / SI or short message. That is, the recording reservation processing unit 230 transmits a short message including the recording reservation information to the mobile communication terminal 100 of the user through the short message service center 40 of the mobile communication network or broadcasts the recording reservation information. And the recording reservation information in the PSI / SI table for providing the channel configuration information and the organization information to the center 300 for transmission to the mobile communication terminal 100 through a broadcasting network. Can be.

4 is a flowchart illustrating a digital multimedia broadcasting program reservation recording service method according to an exemplary embodiment of the present invention.

As shown, when the user accesses the DMB reserved recording service server 200 via wired or wireless Internet and selects a specific broadcast program to request a reserved recording (S101), the DMB reserved recording service server 200 requests the corresponding broadcast program. Recording reservation information including start, end time and channel information of the PSI / SI or short message is transmitted to the mobile communication terminal 100 through a broadcasting network or through a mobile communication network (S102).

The mobile communication terminal 100 determines whether recording reservation information is included in the received PSI / SI or short message (S103). If the recording reservation information is included, the mobile communication terminal 100 extracts the corresponding recording reservation information to determine time information and a channel. Information is stored in the DMB module 110 (S104).

Next, the DMB module 110 drives the RF tuner 111 and the CDM chip 112 when the program start time comes (S105) according to the stored information (S106), and broadcasts the corresponding RF tuner 111. After setting the channel for transmitting the program signal (S107), recording is started (S108).

The recording process (S108) continues until the program end time, the DMB module 110 stops the driving of the RF tuner unit 111 and the CDM chip unit 112 when the program end time (S109). ).

Meanwhile, in the above description, the mobile communication terminal is limited to receiving the recording reservation information through the PSI / SI or the short message. However, the mobile communication terminal may receive the recording reservation information through the system message used in the mobile communication network.

As those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features, the embodiments described above are exemplary in all respects and are not intended to be limiting. You must do it. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

Accordingly, according to the digital multimedia broadcasting program reservation recording service system and method of the present invention and a mobile communication terminal therefor, when the user cannot watch a broadcasting program that the user wants to watch at the corresponding broadcasting time, the mobile communication terminal automatically corresponds to the corresponding broadcasting program. You can schedule recording of the broadcasting program through wired / wireless internet to record the broadcasting program, and you can apply for recording reservation through wired internet, so even if the user does not have a mobile communication terminal, The effect is that the program can be watched later.
