Abstract

An apparatus and method of receiving broadcasting content and generating program summary information corresponding to received broadcasting content, and an apparatus and method of providing the generated program summary information are provided. Real-time broadcasting content may be received through a tuner of a program summary information generating apparatus. The program summary information is extracted from the received real-time broadcasting content, and may be stored and provided to a user via a display unit. In view of the program summary information, a user may understand, for example, the flow of the broadcasting content, even if the user missed a part of the broadcasting content.

Claims

1. A method of generating program summary information in a program summary information generating apparatus including at least one tuner, the method comprising:

receiving real-time broadcasting content through the tuner;

extracting the program summary information from the received real-time broadcasting content; and

storing the extracted program summary information.

2. The method of claim 1, wherein, the extracting of the program summary information comprises:

dividing the received real-time broadcasting content into at least one form of data constituting the received real-time broadcasting content;

extracting related information by extracting a characteristic from each form of data; and

generating the program summary information by use of the extracted related information.

3. The method of claim 2, wherein the divided data includes at least one of video data, audio data, and text data.

4. The method of claim 3, wherein the text data is a closed caption included in the real-time broadcasting content.

5. The method of claim 2, wherein, if the received real-time broadcasting content is divided into at least two forms of data, the program summary information is generated by merging the at least two pieces of the extracted related information.

6. The method of claim 5, wherein the program summary information generated through merging is provided in a form of a still image or a moving image.

7. The method of claim 2, wherein the real-time broadcasting content is segmented into at least one semantic section by use of the extracted related information, and

the program summary information is generated for each segmented semantic section.

8. An apparatus for generating program summary information corresponding to real-time broadcasting content, the apparatus comprising:

a tuner configured to receive the real-time broadcasting content;

an information extraction unit configured to extract the program summary information from the received real-time broadcasting content; and

a storage unit configured to store the extracted program summary information.

9. The apparatus of claim 8, further comprising a display unit configured to display the received real-time broadcasting content and the program summary information.

10. The apparatus of claim 8, wherein the information extraction unit comprises:

a demultiplexing unit configured to divide the received real-time broadcasting content into at least one form of data constituting the received real-time broadcasting content; and

a related information extraction unit configured to extract related information by extracting a characteristic from each form of data.

11. The apparatus of claim 10, wherein the demultiplexing unit divides the received real-time broadcasting content into at least one of video data, audio data, and text data, and the related information extraction unit comprises:

a video related information extraction unit configured to extract information related to the video data;

an audio related information extraction unit configured to extract information related to the audio data; and

a text related information extraction unit configured to extract information related to the text data.

12. The apparatus of claim 10, wherein, if the received real-time broadcasting content is divided into at least two forms of data, the information extraction unit further comprises a related information merging unit configured to merge the at least two pieces of extracted related information.

13. The apparatus of claim 10, further comprising a segmentation unit configured to segment the received broadcasting content into at least one semantic section by use of extracted related information, and

the information extraction unit is configured to generate the program summary information for each semantic section segmented by the segmentation unit.

14. A method of providing program summary information in a broadcasting receiver that receives and displays real-time broadcasting content, the method comprising:

receiving a request for the program summary information regarding the received real-time broadcasting content;

obtaining the program summary information corresponding to the request; and

displaying the obtained program summary information.

15. The method of claim 14, wherein, the obtaining of the program summary information comprises obtaining the program summary information from the broadcasting receiver, or a server connected to the broadcasting receiver through a network.

16. The method of claim 14, wherein, the obtaining of the program summary information is performed by selecting program summary information generated before the request is received, among a plurality of program summary information regarding the real-time broadcasting content when the request is received.

17. The method of claim 14, wherein the program summary information is displayed on a frame different from a frame displaying the real-time broadcasting content.

18. A broadcasting receiver for providing program summary information regarding real-time broadcasting content, the broadcasting receiver comprising:

a receiving unit configured to receive the real-time broadcasting content;

a storage unit configured to store the program summary information;

a display unit configured to output the program summary information; and

a control unit configured to obtain the program summary information corresponding to a request and to output the corresponding program summary information on the display unit.

19. The broadcasting receiver of claim 18, wherein the control unit allows the corresponding program summary information to be obtained from the storage unit, or a server connected to the broadcasting receiver through a network.

20. The broadcasting receiver of claim 18, wherein the control unit is configured to output the program summary information by selecting program summary information generated before the request is received, among a plurality of program summary information regarding the real-time broadcasting content when the request is received.
