Abstract

A basic device used in a linking of the basic device and an extended device includes an extended scene description manager parsing an extended scene descriptor, and a meta data delivery manager extracting meta data from a multimedia stream using the result of parsing and transmitting the extracted meta data to the extended device.

Claims

1. A basic device used in a linking operation of the basic device and an extended device, the basic device comprising:

an extended scene description manager which parses an extended scene descriptor; and

a meta data delivery manager which extracts meta data from a multimedia stream using a result of the parsing of the extended scene descriptor, and which transmits the extracted meta data to the extended device.

2. The basic device of claim 1, further comprising a scene descriptor parser which parses a basic scene descriptor and a scene composition manager which composes motion pictures.

3. The basic device of claim 1, wherein the meta data comprises information on a type of the extended device to be linked, and a content of a linking operation.

4. The basic device of claim 1, wherein the multimedia stream includes an audio stream, a video stream, and a data stream.

5. The basic device of claim 1, wherein the basic device is a multimedia reproduction apparatus.

6. The basic device of claim 5, wherein the multimedia reproduction apparatus is a digital television.

7. An extended device used in a linking operation with a basic device, the extended device comprising:

a meta data receiving portion which receives meta data from a basic device;

a meta data interpretation portion which interprets the received meta data; and

a control portion which performs a linking operation using a result of the interpretation of the meta data.

8. The extended device of claim 7, wherein the extended device includes at least one of an air and humidity control apparatus, a temperature control apparatus, a multimedia display device, an audio output apparatus, and an illumination apparatus.

9. The extended device of claim 7, wherein the meta data comprises information on a type of the extended device to be linked, and a content of the linking operation.

10. A multiform rich media system comprising:

a basic device which reproduces a motion picture using a multimedia stream and extracts meta data from the multimedia stream;

an extended device which performs a linking operation using the meta data; and

an interconnection layer which transmits the meta data to the extended device.

11. The multiform rich media system of claim 10, wherein the interconnection layer is any one of 1394-over-IP, power line communication, universal serial bus, wireless internet protocol, and ultra wide band.

25. The multiform rich media system of claim 10, wherein the meta data includes information on a type of the extended device, and a content of the linking operation.

12. A method of linking an extended device and a basic device, the method comprising:

parsing an extended scene descriptor;

extracting meta data from a multimedia stream using a result of the parsing of the extended scene descriptor;

transmitting the extracted meta data to the extended device; and

performing a linking operation of the extended device with the basic device using the meta data.

13. The method of claim 12, wherein the meta data comprises information on a type of the extended device to be linked, and a content of the linking operation.

14. The method of claim 12, wherein the extended scene descriptor includes an object descriptor ID needed for the extraction of the meta data.

15. The method of claim 12, further comprising determining whether there is a request from a user to link the basic device with the extended device.

16. The method of claim 12, wherein the extended apparatus is an air and temperature control apparatus and the linking operation is a control of at least one of a strength, a direction, and a temperature of air flow.

17. The method of claim 12, wherein the extended device is an illumination apparatus and the linking operation is a control of at least one of a brightness and a color of a ramp.

18. The method of claim 12, wherein the performing of the linking operation of the extended device comprises:

receiving the extracted meta data from the basic device;

determining a content of the linking operation of the extended device by interpreting the extracted meta data; and

performing the linking operation according to the content of the determined linking operation.

19. The method of claim 12, wherein the linking operation of the extended device is synchronized with an operation of the basic device.

20. The method of claim 19, wherein the operation of the basic device is a reproduction of a motion picture and the linking operation of the extended device is a reproduction of a different motion picture or an audio related to a scene of the motion picture.

21. A computer readable recording medium having embodied thereon a computer program for linking a basic device with an extended device, and for storing a stream including a scene descriptor, wherein the scene descriptor comprises:

a general scene descriptor; and

an extended scene descriptor including an identifier of an object descriptor related to meta data.

22. The recording medium of claim 21, further storing the meta data which comprises information on a type of an extended device which performs a linking operation, and a content of the linking operation.

23. A computer readable recording medium having embodied thereon a computer program to execute operations on a computer in linking a basic device and an extended device, wherein the operations comprise:

parsing an extended scene descriptor;

extracting meta data from a multimedia stream using a result of the parsing of the extended scene descriptor;

transmitting the extracted meta data to the extended device; and

performing a linking operation with the extended device and the basic device using the meta data.

24. A computer readable recording medium having embodied thereon a computer program to execute operations on a computer, wherein the operations comprise:

receiving meta data from a basic device;

determining a content of a linking operation of an extended device by interpreting the meta data; and

performing the linking operation according to the content of the determined linking operation.
