First, referring to FIG. 1 , the broadcast management apparatus 100 for a vehicle according to an embodiment of the present invention includes a first receiver 110 , a second receiver 120 , a controller 130 , a processor 140 , and A display unit 150 may be included.

The first receiver 110 may receive a broadcast signal of a selected channel. For example, the first receiver 110 may be controlled by the controller 130 to receive a broadcast signal of a channel selected by the user. For example, the broadcast signal may be a DMB broadcast signal, and the first receiver 110 may be a tuner.

The second receiver 120 may receive a broadcast signal of the same channel as the selected channel or a different channel. Also, the second receiver 120 may receive a data signal. For example, the data signal may be a TPEG data signal. The second receiver 120 may perform at least one of searching for a broadcast signal of another channel and receiving a data signal under the control of the controller 130 .

The controller 130 may control the operations of the first receiver 110 and the second receiver 120 . The controller 130 may control the operation of the second receiver 120 according to the broadcast type of the broadcast signal of the selected channel received by the first receiver 110 . The broadcast type may include a first type that simultaneously provides a DMB broadcast service and a TPEG data service, and a second type that provides only a DMB broadcast service.

For example, when the broadcast type of the broadcast signal of the selected channel received by the first receiver 110 is the first type of broadcast, the controller 130 controls the second receiver 120 to search for a broadcast signal of another channel. can In addition, the controller 130 may check the channel identification information (eg, channel ID) corresponding to the broadcast signal of the other searched channel, and control the second receiver 120 to receive the channel information. The controller 130 may detect channel information having a reference data error rate or higher by checking a data error rate of the received channel information. Through this process, the controller 130 can monitor the signal strength (signal sensitivity) of broadcast signals of other channels through the second receiver 120 , and use channel information having a reference data error rate or higher to list broadcast channels. can be updated.

Also, for example, when the broadcast type of the broadcast signal of the selected channel received by the first receiver 110 is the second type of broadcast, the controller 130 dynamically controls the second based on the signal strength of the broadcast signal of the selected channel. The receiver 120 may control to search for a broadcast signal of another channel and receive a data signal. That is, when the broadcast signal received by the first receiver 110 does not provide the TPEG service, the controller 130 may receive the TPEG data signal through the second receiver 120 and provide it to the user.

On the other hand, as described above, the controller 130 dynamically controls the second receiver 120 to perform a broadcast signal search and data signal reception of another channel based on the signal strength of the broadcast signal of the selected channel, thereby broadcasting other channels. It is possible to control so that the data signal is received without interruption while simultaneously performing the signal search and the data signal reception. This will be described in more detail with reference to FIGS. 2 to 4 below.

For example, in a general case, the controller 130 may control the second receiver 120 to search for a broadcast signal of another channel for 1 minute (BG 1min) and to receive a data signal for 1 minute (Tpeg 1min). have.

Meanwhile, in the present embodiment, when the signal strength of the broadcast signal of the selected channel is equal to or greater than the reference strength (that is, when the current broadcast reception state is good), the control unit 130 may reduce the time allocation for searching for a broadcast signal of another channel ( See Fig. 2 (b)). For example, the controller 130 may vary the time allocation for searching for a broadcast signal of another channel according to the signal strength of the broadcast signal of the selected channel (eg, 30sec, 10sec, 20sec, 3sec, etc.)

That is, when the reception sensitivity of the broadcast signal of the currently received selected channel is good, the controller 130 can control the time allocation for data signal reception to be relatively increased by reducing the time allocation for searching for a broadcast signal of another channel. have. Accordingly, the controller 130 may control the data signal to be received seamlessly. Meanwhile, the controller 130 may maintain a constant time allocation for data signal reception (eg, 1 min).

Referring to FIG. 3 , when the signal strength of a broadcast signal of a selected channel is equal to or greater than a reference strength, the controller 130 may reduce time allocation for searching for a broadcast signal of another channel (see (b) of FIG. 3 , 30sec). Also, the controller 130 may increase the time allocation for data signal reception (eg, 1.5min).

That is, when the reception sensitivity of the broadcast signal of the currently received selected channel is good, the controller 130 may control to reduce the time allocation for searching for a broadcast signal of another channel and increase the time allocation for data signal reception. Accordingly, the controller 130 may control the data signal to be received seamlessly.

Referring to FIG. 4 , when the signal strength of the broadcast signal of the selected channel is equal to or greater than the reference strength, the controller 130 may variably reduce the time allocation for searching for a broadcast signal of another channel (see (b) of FIG. 4 , ex .1min -> 30sec -> 1min).

Also, the controller 130 may maintain or variably increase the time allocation for data signal reception (eg, 1min -> 1.5min -> 1min).

Accordingly, the controller 130 may control the data signal to be received seamlessly.

Referring back to FIG. 1 , when the broadcast signal of the selected channel is the second type of broadcast, the first receiver 110 detects the first type of broadcast signals of other channels retrieved from the second receiver 120 . It is possible to control to receive a broadcast signal that provides a broadcast, and to control the second receiver 120 to search for a broadcast signal corresponding to another channel.

The processing unit 130 may process a broadcast signal and/or a data signal. For example, the processing unit 130 may process a broadcast signal and/or a data signal to be displayed to the user through the display unit 140 .

The display unit 140 may display a broadcast signal and/or a data signal processed by the processing unit 130 . For example, the display unit 140 may include a vehicle cluster screen, an AVN display, a heads-up display, and the like.
