Abstract

Disclosed is a broadcast receiving device. A terrestrial broadcast receiving unit receives a terrestrial broadcasting service. A mobile receiving unit receives a mobile broadcasting service transmitted via a network for mobile communication. A control unit allows the terrestrial broadcasting service and the mobile broadcasting service to be selectively received.

First claim

The invention claimed is:

1. A broadcast receiving device, comprising:
a terrestrial broadcast receiver configured to receive a terrestrial broadcasting service;
a mobile receiver configured to receive a mobile broadcasting service transmitted via a mobile broadcast network for mobile communication; and
a controller configured to allow the terrestrial broadcasting service and the mobile broadcasting service to be selectively received,
wherein the controller is further configured to:
turn on the mobile receiver and receive and store a mobile broadcast service list when the broadcast receiving device is located in a coverage of the mobile broadcast network,
turn on the terrestrial broadcast receiver, scan the terrestrial broadcasting service and store a terrestrial broadcasting service list, and
when the terrestrial broadcasting service is switched to the mobile broadcasting service, start a turn-off timer of the terrestrial broadcast receiver set to a predetermined reference time, and turn off the terrestrial broadcast receiver after the turn-off timer expires so as to keep both of the mobile receiver and the terrestrial broadcast receiver in a turn-on state during the predetermined reference time.

2. The broadcast receiving device according to claim 1 , wherein, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content, the controller allows the terrestrial broadcasting service and the mobile broadcasting service to be selectively received based on the coverage of the mobile broadcast network.

3. The broadcast receiving device according to claim 2 , wherein, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content and the broadcast receiving device is outside the coverage of the mobile broadcast network, the controller allows the terrestrial broadcasting service to be received.

4. The broadcast receiving device according to claim 1 , wherein, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content, the controller allows the terrestrial broadcasting service and the mobile broadcasting service to be selectively received based on whether a fee is charged for reception of the mobile broadcasting service.

5. The broadcast receiving device according to claim 1 , wherein, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content, the controller allows the terrestrial broadcasting service and the mobile broadcasting service to be selectively received based on a capability of the broadcast receiving device.

6. The broadcast receiving device according to claim 1 , wherein, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content, the controller allows the terrestrial broadcasting service and the mobile broadcasting service to be selectively received based on a strength of a mobile broadcast signal and a strength of a terrestrial broadcast signal.

7. A method for operating a broadcast receiving device, the method comprising:
turning on a mobile receiver and receiving and storing a mobile broadcast service list when the broadcast receiving device is located in a coverage of the mobile broadcast network;
turning on a terrestrial broadcast receiver, scanning a terrestrial broadcasting service and storing a terrestrial broadcasting service list;
receiving a user input for selecting a broadcasting service;
selectively receiving the terrestrial broadcasting service and a mobile broadcasting service transmitted via a network for mobile communication, based on the user input; and
when the terrestrial broadcasting service is switched to the mobile broadcasting service, starting a turn-off timer of the terrestrial broadcast receiver set to a predetermined reference time, and turning off the terrestrial broadcast receiver after the turn-off timer expires so as to keep both of the mobile receiver and the terrestrial broadcast receiver in a turn-on state during the predetermined reference time.

8. The method according to claim 7 , wherein the selectively receiving the terrestrial broadcasting service and the mobile broadcasting service comprises:
selectively receiving the terrestrial broadcasting service and the mobile broadcasting service based on the coverage of the mobile broadcast network, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content.

9. The method according to claim 8 , wherein the selectively receiving the terrestrial broadcasting service and the mobile broadcasting service comprises:
receiving the terrestrial broadcasting service, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content and a broadcast receiving device is outside the coverage of the mobile broadcast network.

10. The method according to claim 7 , wherein the selectively receiving the terrestrial broadcasting service and the mobile broadcasting service comprises:
selectively receiving the terrestrial broadcasting service and the mobile broadcasting service based on whether a fee is charged for reception of the mobile broadcasting service, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content.

11. The method according to claim 7 , wherein the selectively receiving the terrestrial broadcasting service and the mobile broadcasting service comprises:
selectively receiving the terrestrial broadcasting service and the mobile broadcasting service based on a capability of a broadcast receiving device, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content.

12. The method according to claim 7 , wherein the selectively receiving the terrestrial broadcasting service and the mobile broadcasting service comprises:
selectively receiving the terrestrial broadcasting service and the mobile broadcasting service based on a strength of a mobile broadcast signal and a strength of a terrestrial broadcast signal, when the terrestrial broadcasting service and the mobile broadcasting service are identical services for transmitting identical broadcast content.
