wherein the power-off mode has a power level that is below a first minimum power level required for displaying the broadcasting signal and is equal to a second minimum power level required for detecting a power-on signal and receiving the broadcasting signal, and

wherein the controller determines, whenever a channel is switched, whether to perform the shunning function based on an authentication of the condition access module and the stored contents information, as determined results, minimizing a delay in channel switching and performs the shunning function according to the determined results.

2. The broadcasting processing apparatus according to claim 1, wherein the controller updates the contents information within at least seven days.

3. The broadcasting processing apparatus according to claim 1, wherein the contents information comprises protection information about whether to protect the contents, and

the controller does not perform the shunning function if the protection information is not to protect the contents.

4. The broadcasting processing apparatus according to claim 1, wherein the contents information comprises scramble information about whether or not the contents are scrambled, and

the controller does not perform the shunning function if the scramble information indicates that the contents are not scrambled.

5. The broadcasting processing apparatus according to claim 1, wherein the contents information comprises at least one of brand information and identification information of the condition access module, and

the controller performs the shunning function if the at least one of the received brand information and the received identification information does not match with at least one of actual brand information and actual identification information of the condition access module.

6. The broadcasting processing apparatus according to claim 1, wherein the condition access module comprises either of a common interface (CI) type or a CI plus (CI+) type, and

the controller determines that the condition access module is not authenticated if the condition access module is the CI type, and performs the shunning function.

7. The broadcasting processing apparatus according to claim 1, further comprising a signal processor which processes the contents, and

if the controller does not perform the shunning function, the contents not scrambled bypasses the condition access module and are input to the signal processor, and the contents scrambled are descrambled by the condition access module and input to the signal processor.

8. The broadcasting processing apparatus according to claim 1, further comprising a display unit which displays the contents.

9. The broadcasting processing apparatus of claim 1, wherein a signal processor processes the broadcasting signal and divides the broadcasting signal into the received additional information for the controller, a video signal for a video processor, and an audio signal for an audio processor.

10. The broadcasting processing apparatus of claim 9, wherein the video processor decodes the video signal, and scales the decoded video signal to have a vertical frequency, a resolution, and an aspect ratio adapted to a standard format of a display unit.

11. The broadcasting processing apparatus of claim 9, wherein the audio processor processes the audio signal and sends the processed audio signal to an audio output unit.

12. The broadcasting processing apparatus of claim 1, wherein the controller performs the shunning function if the contents information indicates that a protection information protects the contents, a scramble information indicates that the contents are scrambled, and the condition access module comprises a common interface (CI) type.

13. The broadcasting processing apparatus of claim 1, wherein the controller does not perform the shunning function if the contents information indicates that a protection information protects the contents, a scramble information indicates that the contents are scrambled, and the condition access module comprises a common interface plus (CI+) type.

14. The broadcasting processing apparatus of claim 1, wherein the controller performs the shunning function if the contents information indicates that a protection information protects the contents, a scramble information indicates that the contents are scrambled, and at least one of the received brand information does not match with at least one of actual brand information of the condition access module.

15. The broadcasting processing apparatus of claim 1, wherein the controller does not perform the shunning function if the contents information indicates that a protection information protects the contents, a scramble information indicates that the contents are scrambled, and at least one of the received brand information does match with at least one of actual brand information of the condition access module.

16. The broadcasting processing apparatus of claim 1, wherein the broadcasting signal is an analog signal.

17. A method of controlling a broadcasting processing apparatus including a broadcasting receiver which receives a broadcasting signal comprising contents and additional information about the contents, and a condition access module which descrambles the contents if the contents have been scrambled, the method comprising:

receiving the additional information during a power-off mode;

storing contents information about a shunning function among the received additional information according to channels, wherein the shunning function prevents an inputting of the contents to the condition access module,

determining whether to perform the shunning function based on an authentication of the condition access module and the stored contents information, whenever a channel is switched, as determined results, minimizing a delay in channel switching; and

performing the shunning function according to the determined results,

wherein the power-off mode has a power level that is below a first minimum power level required for displaying the broadcasting signal and is equal to a second minimum power level required for detecting a power-on signal and receiving the broadcasting signal.

18. The method according to claim 17, wherein the storing the contents information comprises updating the contents information within at least seven days.

19. The method according to claim 17, wherein the contents information comprises protection information about whether to protect the contents, and

the determining whether to perform the shunning function comprises determining not to perform the shunning function if the protection information is not to protect the contents.

20. The method according to claim 17, wherein the contents information comprises scramble information about whether or not the contents are scrambled, and

the determining whether to perform the shunning function comprises determining not to perform the shunning function if the scramble information indicates that the contents are not scrambled.

21. The method according to claim 17, wherein the contents information comprises at least one of brand information and identification information of the condition access module, and

the determining whether to perform the shunning function comprises determining to perform the shunning function if the at least one of the received brand information and the received identification information does not match with at least one of actual brand information and actual identification information of the condition access module.
