Abstract

A broadcasting system and a method for processing data are disclosed. The broadcasting system receives a broadcasting signal including program table information including contents redistribution information, contents edition information and contents protection information and so on. The broadcasting system extracts the received information and stores the contents included in the broadcasting signal, outputs the contents to the outside, or outputs information of the contents in accordance with the extracted information.

Claims

1. A method for processing data, the method comprising:

receiving a broadcasting signal;

demultiplexing program table information from the broadcasting signal;

parsing the demultiplexed program table information; and

extracting at least one of contents protection information, contents redistribution information and contents editing information from the parsed program table information, and storing the contents included in the broadcasting signal in accordance with the extracted information, outputting the contents to the outside, or outputting information of the contents.

2. The method as claimed in claim 1, wherein the contents protection information includes at least one of information as to whether contents can be recorded, information as to whether contents can be copied to the outside, and information of the number of copying times of contents.

3. The method as claimed in claim 1, wherein the contents redistribution information includes at least one of information as to whether contents are redistributed, producer or copywriter information of contents, information of the number of redistribution times of contents, redistribution date information of contents, and redistributor information of contents.

4. The method as claimed in claim 1, wherein the contents editing information includes at least one of information as to whether contents are edited, aspect ratio information of contents before editing, aspect ratio information of edited contents, information of the number of elementary streams included in contents before editing, type information of elementary streams included in contents before editing, language information of audio elementary streams included in contents before editing, surround mode information of audio elementary streams included in contents before editing, service mode information of audio elementary streams included in contents before editing, information of the number of channels of audio elementary streams included in contents before editing, information as to whether to provide full service of audio elementary streams included in contents before editing, duration information of contents before editing, duration information of edited contents, information of the number of rating regions (rating_region) of contents before editing, information of rated regions of contents before editing, information of rating dimension of contents before editing, rating information of contents before editing, and description information of rating of contents before editing.

5. A digital broadcasting system comprising:

a receiver receiving a broadcasting signal;

a demultiplexer demultiplexing program table information from the broadcasting signal;

a data decoder parsing the demultiplexed program table information;

a controller obtaining contents protection information from the program table information parsed by the data decoder and controlling whether to control contents included in the broadcasting signal in accordance with the contents protection information;

a storage module storing the contents; and

a storage controller controlling the storage module to store the contents in the storage module under the control of the controller.

6. The digital broadcasting system as claimed in claim 5, further comprising an input and output interface outputting the contents stored in the storage module to the outside in accordance with the contents protection information.

7. The digital broadcasting system as claimed in claim 5, wherein the contents protection information includes at least one of information as to whether contents can be recorded, information as to whether contents can be copied to the outside, and information of the number of copying times of contents.

8. The digital broadcasting system as claimed in claim 5, wherein the data decoder further parses contents redistribution information from the program table information, and the digital broadcasting system further comprises an output module outputting the parsed contents redistribution information under the control of the controller.

9. The digital broadcasting system as claimed in claim 8, wherein the contents redistribution information includes at least one of information as to whether contents are redistributed, producer or copywriter information of contents, information of the number of redistribution times of contents, redistribution date information of contents, and redistributor information of contents.

10. The digital broadcasting system as claimed in claim 5, wherein the data decoder further parses contents editing information from the program table information, and the digital broadcasting system further comprises an output module outputting the parsed contents editing information under the control of the controller.

11. The digital broadcasting system as claimed in claim 10, wherein the contents editing information includes at least one of information as to whether contents are edited, aspect ratio information of contents before editing, aspect ratio information of edited contents, information of the number of elementary streams included in contents before editing, type information of elementary streams included in contents before editing, language information of audio elementary streams included in contents before editing, surround mode information of audio elementary streams included in contents before editing, service mode information of audio elementary streams included in contents before editing, information of the number of channels of audio elementary streams included in contents before editing, information as to whether to provide full service of audio elementary streams included in contents before editing, duration information of contents before editing, duration information of edited contents, information of the number of rating regions (rating_region) of contents before editing, information of rated regions of contents before editing, information of rating dimension of contents before editing, rating information of contents before editing, and description information of rating of contents before editing.
