Abstract

A broadcast receiver which can scale up broadcast-related information displayed on a screen using a data service and a method of controlling the broadcast receiver are provided. The broadcast receiver receives a broadcast signal, extracts broadcast program data from the broadcast signal, and displays the broadcast program data on a screen. Also, the broadcast receiver extracts broadcast-related information from the broadcast signal and stores the broadcast-related information. When a broadcast-related information scale-up mode is selected, the broadcast receiver withdraws the broadcast-related information and displays the broadcast-related information on the screen. In this manner, it is possible to display broadcast-related information on a screen so that a user can easily recognize the broadcast-related information from the screen.

Claims

1. A method of controlling a broadcast receiver, the method comprising:

receiving a broadcast signal;

extracting broadcast program data from the broadcast signal and displaying the broadcast program data;

extracting broadcast-related information from the broadcast signal and storing the broadcast-related information in a memory; and

obtaining the broadcast-related information from the memory and then displaying the obtained broadcast-related information when a broadcast-related information scale-up mode is selected.

2. The method of claim 1, wherein the broadcast-related information is text information.

3. The method of claim 1, wherein the broadcast-related information is Binary Format for Scene (BIFS)-encoded.

4. The method of claim 1, wherein the displaying the broadcast-related information comprises:

scaling up the broadcast-related information; and

displaying the scaled-up broadcast-related information as one of a popup window and a transparent window.

5. The method of claim 1, further comprising:

generating a transport stream (TS) by combining the broadcast program data and the broadcast-related information, the broadcast-related information being encoded; and

generating the broadcast signal by modulating the TS.

6. The method of claim 1, wherein the displaying the broadcast-related information comprises outputting a sound signal corresponding to the broadcast-related information.

7. The method of claim 1, wherein the broadcast signal is a digital multimedia broadcasting (DMB) signal.

8. A method of controlling a broadcast receiver, the method comprising:

generating broadcast-related information which can be selectively displayed by a broadcast receiver;

generating a TS by encoding the broadcast-related information and combining the encoded broadcast-related information with broadcast program data;

generating a broadcast signal by modulating the TS; and

transmitting the broadcast signal to the broadcast receiver.

9. The method of claim 8, wherein the broadcast-related information is text information.

10. The method of claim 8, wherein the encoding the broadcast-related information comprises BIFS-encoding the broadcast-related information.

11. The method of claim 8, further comprising:

receiving the broadcast signal and extracting the broadcast program data from the broadcast signal; and

extracting the broadcast-related information from the broadcast signal and then displaying the broadcast-related information when a broadcast-related information scale-up mode is selected.

12. The method of claim 8, wherein the broadcast signal is a DMB signal.

13. A system for controlling a broadcast receiver, the system comprising:

a broadcast receiver which receives a broadcast signal, extracts broadcast program data from the broadcast signal, displays the broadcast program data, and extracts broadcast-related information from the broadcast signal and then displays the broadcast-related information when a broadcast-related information scale-up mode is selected; and

a broadcast signal transmitter which generates a TS by encoding the broadcast-related information and combining the encoded broadcast-related information with the broadcast program data, generates the broadcast signal by modulating the TS, and transmits the broadcast signal to the broadcast receiver.

14. The system of claim 13, wherein the broadcast receiver scales up the broadcast-related information on a screen and displays the scaled-up broadcast-related information as one of a popup window and a transparent window.

15. A broadcast receiver, comprising:

a signal receiver which receives a broadcast signal and extracts broadcast program data and broadcast-related information from the broadcast signal;

a display unit which displays the broadcast program data; and

a controller which controls the broadcast-related information to be displayed by the display unit when a broadcast-related information scale-up mode is selected.

16. The broadcast receiver of claim 15, wherein the broadcast-related information is text information.

17. The broadcast receiver of claim 15, further comprising a memory unit which stores the broadcast-related information.

18. The broadcast receiver of claim 15, wherein the broadcast-related information is BIFS-encoded.

19. The broadcast receiver of claim 15, further comprising a key input unit which receives an input for selecting the broadcast-related information scale-up mode.

20. The broadcast receiver of claim 15, wherein the controller controls the broadcast-related information to be scaled up on a screen and then to be displayed as one of a popup window and a transparent window.

21. The broadcast receiver of claim 15, further comprising a sound processing unit which outputs a sound signal corresponding to the broadcast-related information under the control of the controller.

22. The broadcast receiver of claim 15, further comprising a wireless communication unit which provides a mobile communication function under the control of the controller.

23. The broadcast receiver of claim 15, wherein the broadcast signal is a DMB signal.

24. A method of controlling a broadcast receiver, the method comprising:

extracting broadcast-related information from a broadcast signal; and

displaying a scaled-up version of the broadcast-related information when a broadcast-related information scale-up mode is selected.
