Abstract

A method for providing keywords and a video apparatus applying the method are provided. The method for providing keywords includes separating metadata from content, extracting keywords in the content from the metadata, and generating a keyword list using the keywords and images related to the keywords. It is thus possible to display the keywords together with the images related to the keywords, so a user may register desired keywords more conveniently without needing to manually individually input keywords.

Claims

1. A method for providing keywords, the method comprising:

separating metadata from content;

extracting keywords in the content from the separated metadata; and

generating a keyword list using the extracted keywords and images related to the keywords.

2. The method of claim 1, wherein the generating the keyword list comprises:

determining whether the images related to the keywords have been stored previously; and

if it is determined that the images related to the keywords have been stored previously, generating a keyword list using the keywords and the previously stored images.

3. The method of claim 2, further comprising, if it is determined that the images related to the keywords have not been stored previously,

determining whether there is a connection to a network;

and

searching for the images related to the keywords through the network,

wherein the generating the keyword list further comprises generating a keyword list using the keywords and the images found during the search.

4. The method of claim 3, wherein the generating the keyword list further comprises:

generating a keyword list using the keywords and using icons previously stored instead of the images related to the keywords, if it is determined that there is no connection to the network and the images related to the keywords have not been stored previously.

5. The method of claim 1, wherein the content is broadcasting content.

6. The method of claim 1, wherein the keyword list comprises a plurality of items, each of which comprises a corresponding pair of one of the keywords and one of the images uniquely matched to the keyword.

7. The method of claim 1, further comprising:

displaying the generated keyword list; and

if a command to register at least one of the keywords is selected from the displayed keyword list is received, registering the selected keyword together with the corresponding image related to the selected keyword and displayed with the keyword on the displayed keyword list.

8. A video apparatus, comprising:

a keyword extracting unit to extract keywords in content currently played back;

an image storage unit to store images;

an image search unit to search for stored images from the image storage unit related to the extracted keywords received from the keyword extracting unit; and

a keyword list generator to generate a keyword list using the extracted keywords received from the keyword extracting unit and corresponding stored images received as a result of the search from the image search unit.

9. The video apparatus of claim 8, further comprising:

an interface connected to an Internet protocol network,

wherein, if it is determined that the images related to the keywords are not stored in the image storage unit, the image search unit determines whether the interface is connected to the network; and

if it is determined that the interface is connected to the network, the image search unit searches for the images related to the keywords through the network.

10. The video apparatus of claim 9, wherein, if it is determined that the interface is not connected to the network, the image search unit searches for icons previously stored in the image storage unit instead of the images related to the keywords.

11. The video apparatus of claim 8, wherein the content is broadcasting content.

12. The video apparatus of claim 8, wherein the keyword list comprises a plurality of items, each of which comprises a corresponding pair of one of the extracted keywords uniquely matched to a corresponding one of images.

13. The video apparatus of claim 8, further comprising:

a display; and

a controller to display the keyword list on the display, if a specific user command is input.

14. The video apparatus of claim 8, further comprising:

an input unit through which the content is received;

a demultiplexer to divide the received content into main content and sub-content;

an audio/video processor to process the divided main content to provide video and/or audio data; and

a metadata separator to extract metadata from the sub-content, wherein the keyword extracting unit extracts the keywords from the extracted metadata.

15. The video apparatus of claim 14, further comprising a display on which the video data and the generated keyword list are selectively displayed.

20. The video apparatus of claim 8, further comprising a network interface, wherein the image search unit connects to an external storage device through the network interface to select at least one of the images stored on the external storage device.

21. The video apparatus of claim 20, wherein the external storage device is connected to the network interface via an Internet protocol network.

22. The video apparatus of claim 20, further comprising a local storage unit within the video apparatus, wherein the image search unit selects other ones of the images stored on the local storage unit and selects the at least one of the images stored on the external storage device.

23. The video apparatus of claim 22, wherein the image search unit selects the at least one of the images stored on the external storage device when it is determined that the at least one image is not stored on the local storage unit.

16. A method for providing keywords, the method comprising:

extracting keywords from content received at an apparatus, the keywords being descriptive of the content;

selecting images corresponding to the extracted keywords; and

generating a keyword list using the extracted keywords and the selected images.

17. The method of claim 16, wherein the selecting the images comprises, for each keyword,

detecting if an image exists on a storage unit of the apparatus which corresponds to the keyword,

if the image exists on the storage unit, selected the stored image, and

if the image does not exist on the storage unit, establishing a network connection to select the image from a storage unit exterior to the apparatus.

18. The method of claim 16, wherein the content is retrieved from one or more storage media.

19. A computer readable medium encoded with processing instructions for executing the method of claim 16 using one or more computers.
