The operation of the DMB receiving system configured as described above is as follows.

The DMB receiving unit 100 is to receive and watch a broadcast signal of a channel selected by the user, and the battery level detecting unit 103 is mounted on the DMB receiving unit 100 while the user watches the corresponding broadcast. Check the battery level continuously.

The controller 102 mounted on the DMB receiving unit 100 transmits a battery remaining shortage signal to the mobile network repeater 200 when the remaining battery level detected by the battery remaining amount detecting unit 103 is less than or equal to a preset reference value. And, when receiving the remaining battery low signal from the DMB receiving unit 100, the repeater 200 notifies the mobile communication company base station 300, and transmits the channel information currently viewed by the receiver to the channel manager 400 do.

Then, the channel manager 400 processes the received channel information into 'Start_Recording' which is a command for transmitting out-of-band information so that the information can be received through the second tuner 502 for receiving out-of-band information. The command is transmitted to the second tuner 502.

Subsequently, when the recording command of 'Start_Recording' is input through the second tuner 502, the video display device 500 selects the corresponding channel according to the channel information received through the second tuner 502. The control command is output to the first tuner 501.

Subsequently, the controller 505 outputs a command so that the broadcast signal received through the first tuner 501 can be stored in the first storage unit 508. Then, the DMB receiver 100 starts recording the broadcast of the same channel as the broadcast received by the DMB receiver 100 and ends when the recording is completed.

In addition, according to various user request commands input through the key input unit 506, the control unit 505 controls the control to be made, according to the control signal of the control unit 505 and the display unit 511 and The video and audio are controlled through the speaker 513.

Referring to Figure 3 of the control method of the DMB receiving system according to the present invention configured as described above, the user first powers on the DMB receiver and then watches the desired broadcast through the DMB receiver according to the user's request (S101 to S102).

Then, the battery level is measured while watching the desired broadcast through the DMB receiver (S103).

Subsequently, it is determined whether the measured battery remaining amount has a value smaller than a preset reference value (S104).

As a result of the determination (S104), if the measured battery remaining value is smaller than the preset reference value, the repeater notifies the battery is not present (S105).

The repeater informs the base station of this (S106).

Subsequently, the base station transmits the viewing information that the viewer is watching to the corresponding channel manager (S107).

Then, the channel manager transmits the corresponding channel information to the image display device designated by the user (S108).

Subsequently, the image display device having received the corresponding information starts to record a broadcast (S109).

In addition, when all recording is completed (S110).

On the other hand, if the determination result (S104), the measured battery remaining amount is larger than the preset reference value and ends when the power-off command is input to the DMB receiving unit (S111).

EXAMPLE

In the control method of the DMB receiving system according to the present invention, if the broadcast that the user was watching through the DMB receiving unit 100 is a retransmission broadcasting program, the charging of the DMB receiving unit 100 is completed and the mobile communication company base station 300 is completed. In addition, the base station 300 transmits the broadcast from the time when the user transmits the battery remaining low message to the corresponding DMB receiving unit 100.

Then, the channel manager 400 processes the 'Stop_Recording' command and transmits it to the second tuner 502 so that the recording does not continue anymore.

Referring to FIG. 4, first, a user powers on a DMB receiver and receives a desired image (S201 to S202).

The battery remaining amount is determined while receiving a desired image through the DMB receiving unit (S203).

In operation S204, it is determined whether the determined battery remaining amount is equal to or less than a predetermined reference value.

Subsequently, in the determination result (S204), if the determined battery level is less than or equal to a preset reference value, it is determined that the battery level is insufficient. At this time, it is determined whether the program being viewed is a retransmission program (S205).

As a result of the determination (S205), the retransmission program notifies the repeater that the battery is not present, and the repeater notifies this to the base station (S206).

Then, the base station transmits the viewing information that the viewer is watching to the channel manager (S207).

In addition, the channel manager transmits the corresponding channel information to the image display device designated by the user (S208).

In operation S209, the video display device which has received the corresponding information starts to record a broadcast.

On the other hand, it is determined whether the charging of the DMB receiver is completed while recording is performed in the video display device (S210).

As a result of the determination (S210), when the charging of the DMB receiver is completed, the base station transmits the broadcast from the time when the base station transmits a low battery message to the DMB receiver (S211).

The channel manager transmits a recording stop command to the corresponding video display device, and returns to step S203 until the DMB receiver power-off command is issued (S212 to S213).

On the other hand, when the determination result (S205), if the received program is not a retransmission program, the battery remaining information is notified to the repeater, the repeater informs the base station (S214).

The base station transmits the viewing information that the viewer is watching to the channel manager (S215).

Then, the channel manager transmits the corresponding channel information to the image display device designated by the user (S216). At this time, the recording command is simultaneously transmitted.

Subsequently, the image display device having received the corresponding information starts to record the broadcast of the corresponding channel (S217).

Then, when the recording is completed and the power of the DMB receiver is turned off (S218).

As described above, the DMB receiving system and the control method thereof according to the present invention may be a video display device that is set by the user through the return path of the DMB receiving unit when viewing of the broadcasting through the DMB receiving unit is no longer possible due to low battery. As the channel information is transmitted, the recording is made automatically.

As described above, the DMB receiving system and its control method according to the present invention have the following effects.

First, when viewing is stopped due to low battery while watching by the DMB receiving unit, the user may watch all the desired broadcasts by automatically recording from this point on the image display device preset by the user.

Second, the user satisfaction can be improved by watching all the desired broadcast.

Third, in the case of a retransmission broadcast program, when the battery of the DMB receiver is recharged, the broadcast program before the retransmission can be continuously viewed, thereby providing more convenience to the user.
