Abstract

A method and video device are disclosed for accessing information. In an embodiment of the present invention, part of data included in a title, being played, read from a storage medium or extracted from a broadcast signal is extracted and sent to a server over a network, and information corresponding to the part of the data (i.e., information related to the data and complete data of the data) is received from the server and played. Rather than the part of the data, information related to a position of the data, (e.g. a time point at which the playing of the data starts within the title or a radial position or a physical address at which the data is located in the storage medium) may be sent. The data may be data that forms audio, a frame-shaped video clip or a frame-shaped picture included in the title.

Claims

1. A method of accessing information, comprising:

extracting part of data included in a title being played;

sending the part of the data to a server over a network;

receiving information corresponding to the part of the data from the server; and

playing the information.

2. The method as set forth in claim 1, wherein the part of the data sent to the server comprises a payload of the data corresponding to a predetermined time period time and/or region.

3. The method as set forth in claim 1, wherein the part of the data sent to the server comprises header information of the data.

4. The method as set forth in claim 3, wherein the header information includes information for connection to the server.

5. The method as set forth in claim 1, wherein the data comprises data that forms any one of audio, a frame-shaped video clip and a frame-shaped picture included in the title.

6. The method as set forth in claim 1, wherein the information corresponding to the part of the data is at least one of information related to the data and complete data of the data.

7. The method as set forth in claim 1, further comprising searching in a database of the server for the information corresponding to the data based on the sent part of the data.

8. The method as set forth in claim 1, wherein the tide is any one of a title included in and played from a playable storage medium, a title played from a recordable storage medium on which externally input contents are recorded, and a broadcast program received from a broadcast receiver.

9. The method as set forth in claim 8, wherein identification (1D) information of the playable storage medium is additionally sent to the server along with the part of the data if the title is a title that is included in and played from the playable storage medium, and ID information of the program is sent to the server along with the part of the data if the title is a broadcast program.

10. The method as set forth in claim 9, wherein information related to the data and/or complete data of the data are managed based on the ID information in a database of the server.

11. A method of accessing information, comprising:

sending information related to a position of data included in a title being played to a server via a network along with identification (ID) information of the title; and

receiving information corresponding to the data from the server and playing the information.

12. The method as set forth in claim 11, wherein the information related to the position corresponds to information about a time point at which the playing of the data starts within the title.

13. The method as set forth in claim 11, wherein the title is a title included in a playable storage medium and is played from the playable storage medium or a broadcast program received from a broadcast receiver.

14. The method as set forth in claim 13, wherein if the title is a title included in a playable storage medium and is played from the playable storage medium, the information related to the position is a radial position or a physical address at which the data is located in the storage medium.

15. The method as set forth in claim 11, wherein the data is data that forms any one of audio, a frame-shaped video clip and a frame-shaped picture included in the title.

16. The method as set forth in claim 11, wherein the information corresponding to the data is at least one of information related to the data and complete data of the data.

17. The method as set forth in claim 11, wherein information related to the data and/or complete data of the data are managed based on the ID information in a database of the server.

18. A video device comprising:

a reading/recording unit for recording video data on a storage medium or reading a title from a storage medium and playing the title;

a communication interface for connecting to a server via a network and sending and receiving data; and

a controller for controlling the reading/recording unit and the communication interface so as to send part of data included in a title played from the storage medium, or information about a position of the data and ID information of the title, to the server, and to receive information corresponding to the data from the server and play the information.

19. The video device as set forth in claim 18, wherein the part of the data sent to the server comprises a payload of the data corresponding to a predetermined time period time and/or region or header information of the data.

20. The video device as set forth in claim 18, wherein the information related to the position comprises information about a time point at which the playing of the data starts within the title or a radial position or a physical address at which the data is located in the storage medium.

21. The video device as set forth in claim 18, wherein the data comprises data that forms any one of audio, a frame-shaped video clip and a frame-shaped picture included in the title.

22. The video device as set forth in claim 18, wherein the information corresponding to the part of the data is at least one of information related to the data and complete data of the data.

23. The video device as set forth in claim 18, further comprising:

a broadcast reception unit for receiving and playing a broadcast program;

wherein the controller controls the broadcast reception unit and the communication interface so as to send part of data included in the broadcast program title being played, or information about a position of the data and ID information of the title, to the server, and to receive information corresponding to the data from the server and play the information.

24. The video device as set forth in claim 18, wherein information related to the data and/or complete data of the data are managed based on the ID information in a database of the server.
