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 network device of searching for additional data on audio data during outputting a content, the network device comprising:

a receiver configured to receive the content including audio data multiplexed with video data;

a video decoder configured to decode the video data included in the content and to output the decoded video data;

an audio decoder configured to decode the audio data included in the content and to output the decoded audio data;

a controller configured to extract a part of the outputted audio data without the outputted video data included in the content for a time duration after a user'"'"'s first request; and

a communication interface configured to access at least two content provider (CP) servers, and the communication interface is further configured;

to send the extracted audio data to a first CP server, and

to receive additional data on the extracted audio data from the first CP server,

wherein the video decoder to output the additional data from the first CP server, and the audio decoder to output full music corresponding to the part of the outputted audio data, wherein the full music is received from a second CP server.

2. The network device of claim 1, wherein the time duration depends based on a time point of the user'"'"'s first request.

3. The network device of claim 1, wherein the communication interface stores the full music into a memory according to a user'"'"'s second request.

4. The network device of claim 1, wherein the controller controls the communication interface to access the second CP server by using a specific Uniform Resource Locator (URL).

5. The network device of claim 4, wherein the specific URL is included in the additional data.

6. The network device of claim 1, wherein the additional data comprises at least one of a song ID, a song name, a singer name, and lyrics.

7. A method of searching for additional data on audio data during outputting a content in a network device, the method comprising:

receiving the content including audio data multiplexed with video data;

decoding the video data included in the content and outputting the decoded video data;

decoding the audio data included in the content and outputting the decoded audio data;

extracting a part of the outputted audio data without the outputted video data included in the content for a time duration after a user'"'"'s first request;

accessing at least two content provider (CP) servers;

sending the extracted audio data to a first CP server;

receiving additional data on the extracted audio data from the first CP server;

outputting the received additional data from the first CP server; and

outputting full music corresponding to the part of the outputted audio data, wherein the full music is received from a second CP server.

8. The method of claim 7, wherein the time duration depends based on a time point of the user'"'"'s first request.

9. The method of claim 7, further comprising:

storing the full music into a memory according to a user'"'"'s second request.

10. The method of claim 7,

wherein the full music is received from the second CP server by using a specific Uniform Resource Locator (URL).

11. The method of claim 10, wherein the specific URL is included in the additional data.
