Abstract

An apparatus for providing object information in a multimedia system includes: a receiver configured to receive multimedia contents from a content provider; a parser configured to parse the received multimedia contents and store output information in a memory, the output information corresponding to playback time of objects existing inside the multimedia contents; a controller configured to receive playback time of the multimedia contents from an event generation device, synchronize with the event generation device using the received playback time of the multimedia contents, and receive event information when an event is generated by the event generation device; a comparator configured to retrieve output information corresponding to the event information from the memory; and a display unit configured to display the retrieved output information.

Claims

1. An apparatus for providing object information in a multimedia system, comprising:

a receiver configured to receive multimedia contents from a content provider;

a parser configured to parse the received multimedia contents and store output information in a memory, the output information corresponding to playback time of objects existing inside the multimedia contents;

a controller configured to receive playback time of the multimedia contents from an event generation device, synchronize with the event generation device using the received playback time of the multimedia contents, and receive event information when an event is generated by the event generation device;

a comparator configured to retrieve output information corresponding to the event information from the memory; and

a display unit configured to display the retrieved output information.

2. The apparatus of claim 1, wherein the multimedia contents comprise scene-based object information and time information.

3. The apparatus of claim 1, wherein the parser comprises a XML parser and an object information parser.

4. The apparatus of claim 1, wherein the output information comprises information regarding objects inside the received contents and information regarding playback positions of the objects.

5. The apparatus of claim 1, wherein the event information comprises information regarding time at which the event has been generated by the event generation device and information regarding the position in which the event has occurred.

6. The apparatus of claim 1, wherein the comparator is configured to retrieve objects from the memory using the time information, the objects being played at the time at which the event has occurred.

7. The apparatus of claim 6, wherein the comparator is configured to retrieve object information regarding objects corresponding to the position information, among the retrieved objects, from the memory.

8. The apparatus of claim 1, wherein the memory is configured to store playback start time of objects belonging to the contents, playback end time of the objects, and playback position coordinates of the objects.

9. A method for providing object information in a multimedia system, comprising:

receiving multimedia contents from a content provider;

parsing the received multimedia contents and storing output information in a memory, the output information corresponding to playback time of objects existing inside the multimedia contents;

receiving playback time of the multimedia contents from an event generation device and synchronizing with the event generation device using the received playback time of the multimedia contents;

receiving event information when an event is generated by the event generation device and retrieving output information corresponding to the event information from the memory; and

displaying the retrieved output information.

10. The method of claim 9, wherein the multimedia contents comprise scene-based object information and time information.

11. The method of claim 9, wherein in said parsing the received multimedia contents and storing output information in a memory, the output information corresponding to playback time of objects existing inside the multimedia contents,

the multimedia contents are parsed using a XML parser and an object information parser.

12. The method of claim 9, wherein the output information comprises information regarding objects inside the received contents and information regarding playback positions of the objects.

13. The method of claim 9, wherein the event information comprises information regarding time at which the event has been generated by the event generation device and information regarding the position in which the event has occurred.

14. The method of claim 9, wherein in said receiving event information when an event is generated by the event generation device and retrieving output information corresponding to the event information from the memory,

objects are retrieved from the memory using the time information, the objects being played at the time at which the event has occurred.

15. The method of claim 14, wherein in said receiving event information when an event is generated by the event generation device and retrieving output information corresponding to the event information from the memory,

object information regarding objects corresponding to the position information, among the retrieved objects, is retrieved from the memory.

16. The method of claim 9, wherein the memory stores playback start time of objects belonging to the contents, playback end time of the objects, and playback position coordinates of the objects.
