Abstract

Disclosed herein is a signal processing apparatus including a receiving unit configured to receive a signal transmitted through a media channel and a controller configured to determine whether the signal includes a data download command and to change a channel of the receiving unit to receive data when the signal includes the data download command.

First claim

1 . A signal processing apparatus, comprising:
a receiving unit configured to receive a signal transmitted through a media channel; and a controller configured to determine whether the signal comprises a data download command and to change a channel of the receiving unit to receive data when the signal comprises the data download command.

2 . The signal processing apparatus according to claim 1 , wherein the controller generates a media image based on the signal and determines whether the media image comprises a command pattern corresponding to the data download command.

3 . The signal processing apparatus according to claim 2 , wherein the controller determines whether the signal comprises the data download command by comparing a media image histogram of the media image and a command pattern histogram of the command pattern.

4 . The signal processing apparatus according to claim 1 , wherein the controller determines whether the signal comprises a command code corresponding to the data download command.

5 . The signal processing apparatus according to claim 1 , wherein the controller changes the channel of the receiving unit to a preset data channel to receive the data.

6 . The signal processing apparatus according to claim 1 , wherein the controller changes the channel of the receiving unit in accordance with channel information included in the data download command.

7 . The signal processing apparatus according to claim 1 , wherein the controller changes the channel of the receiving unit to the media channel when data download is terminated.

8 . The signal processing apparatus according to claim 1 , further comprising a storage unit configured to store data,
wherein the controller controls the receiving unit to store received data in the storage unit.

9 . The signal processing apparatus according to claim 1 , wherein the data comprises program data to drive the signal processing apparatus and information data comprising supplementary information to be provided to a user.

10 . The signal processing apparatus according to claim 9 , wherein the controller controls a display apparatus to display the media image generated based on the signal and the supplementary information.

11 . The signal processing apparatus according to claim 5 , wherein a data signal received through the data channel further comprises a substitute image to be displayed while the data is being received.

12 . A method of processing a signal, the method comprising:
receiving a media by receiving a signal transmitted through a media channel; determining whether the signal comprises a data download command; and receiving data by changing a currently receiving channel to receive data when the signal comprises the data download command.

13 . The method according to claim 12 , wherein the determining comprises:
generating a media image based on the signal; and determining whether the media image comprises a command pattern corresponding to the data download command.

14 . The method according to claim 13 , wherein the determining whether the media image comprises the command pattern comprises:
generating a first histogram of the media image; and comparing the first histogram with a second histogram of the command pattern.

15 . The method according to claim 12 , wherein the receiving of data comprises changing the currently receiving channel based on information about a data channel included in the data download command.

16 . The method according to claim 12 , further comprises changing the currently receiving channel to the media channel when the receiving of data is terminated.

17 . A broadcasting system, comprising:
a transmitting apparatus configured to transmit a media signal through a media channel and transmit a data signal through a data channel; a signal processing apparatus configured to change a currently receiving channel to the data channel when the media signal comprises a data download command; and a display apparatus configured to display a screen in accordance with a control of the signal processing apparatus.

18 . The broadcasting system according to claim 17 , wherein the display apparatus displays a media image generated based on the media signal and supplementary information included in the data signal.

19 . The broadcasting system according to claim 17 , wherein the data signal comprises a substitute image to be displayed on the display apparatus while data is downloaded.

20 . A method, comprising:
receiving a media signal through a media channel; switching reception to a data channel when the media signal includes a data command; and generating an image using the media signal as controlled by control data downloaded pursuant to the data command.
