Abstract

A reproducing apparatus includes a reproducing section picking up any signals compressed in a plurality of different compression methods from a recording medium. The recording medium records the signals compressed in a plurality of different compression methods and record management information denoting association of the signals compressed in a plurality of different compression methods with each other, respectively. A decoding section decodes the signal picked up from said recording medium, and a recording section records reproduction management information including reproduction-interruption information in the reproducing section associated with the record management information onto the recording medium.

Claims

1. A method, comprising:

reproducing a broadcast program on a first reproduction apparatus;

interrupting the reproduction of the broadcast program on the first reproduction apparatus in response to a user input;

defining interruption information which represents where the broadcast program was interrupted on the first reproduction apparatus in response to the user input;

recording the interruption information on a recording medium; and

reproducing the broadcast program on a second reproduction apparatus, from where the broadcast program was interrupted on the first reproduction apparatus, based on the interruption information recorded on the recording medium;

wherein the second reproduction apparatus is different from the first reproduction apparatus.

2. The method of claim 1, wherein the reproduced broadcast program at the second reproduction apparatus comprises at least one of (i) the entire broadcast program and (ii) the remainder of the broadcast program from where the broadcast program was interrupted on the first reproduction apparatus.

3. The method of claim 1, wherein the broadcast program includes AV data having different bit rates.

4. The method of claim 3, wherein the different bit rates include at least one of MPEG2, MPEG4, QuickTime file, Flash, JPEG, and stream based on JPEG.

5. The method of claim 4, wherein the broadcast program includes AV data having different bit rates for reproduction at the first reproduction apparatus and second reproduction apparatus.

6. The method of claim 1, wherein at least one of the broadcast program and the interruption information is stored in a recording medium affiliated with at least one of the first reproduction apparatus and second reproduction apparatus.

7. The method of claim 6, wherein the recording medium is at least one of a hard drive, a flash memory, and a ROM affiliated with at least one of the first reproduction apparatus and the second reproduction apparatus.

8. The method of claim 1, wherein at least one of the broadcast program and the interruption information is communicated using a transmission medium that includes at least one of the internet, light waves, radio waves, and acoustic waves.

9. The method of claim 1, wherein at least one of the first reproduction apparatus and the second reproduction apparatus includes at least one of a computer, a portable device, and a computer affiliated with a display.

10. A method, comprising:

communicating, using a transmission medium, a broadcast program to a first reproduction apparatus;

receiving interruption information which represents where the broadcast program was interrupted on the first reproduction apparatus, the interruption of the broadcast program on the first reproduction apparatus occurring in response to a user input;

recording the interruption information on a recording medium; and

communicating, using the transmission medium, the broadcast program on a second reproduction apparatus, from where the broadcast program was interrupted on the first reproduction apparatus, based on the interruption information recorded on the recording medium;

wherein the second reproduction apparatus is different from the first reproduction apparatus.

11. The method of claim 10, wherein the broadcast program communicated to the second reproduction apparatus is comprising at least one of (i) the entire broadcast program and (ii) the remainder of the broadcast program from where the broadcast program was interrupted on the first reproduction apparatus.

12. The method of claim 10, wherein the broadcast program and interruption information are stored in a recording medium and communicated using the transmission medium.

13. The method of claim 12, wherein the recording medium is at least one of a hard drive, a flash memory, and a ROM affiliated with at least one of the first reproduction apparatus and the second reproduction apparatus.

14. The method of claim 10, wherein the transmission medium includes at least one of the Internet, light waves, radio waves, and acoustic waves.

15. The method of claim 10, wherein the broadcast program includes AV data having different bit rates.

16. The method of claim 15, wherein the different bit rates include at least one of MPEG2, MPEG4, QuickTime file, Flash, JPEG, and stream based on JPEG.

17. The method of claim 15, wherein the broadcast program communicated to the first reproduction apparatus and the second reproduction apparatus have different bit rates.

18. The method of claim 10, wherein at least one of the first reproduction apparatus and the second reproduction apparatus includes at least one of a computer, a portable device, and a computer affiliated with a display.

19. A reproducing apparatus, comprising:

a reproducing unit that reproduces video data; and

a defining unit that defines interruption information which represents where the reproducing unit interrupts a reproduction of the video data, the interruption of the video data by the reproducing unit occurring in response to a user input;

wherein the interruption information is recorded on a recording medium;

wherein a second reproducing apparatus reproduces the video data, from where the reproducing unit interrupts a reproduction of the video data, based on the interruption information recorded on the recording medium; and

wherein the second reproducing apparatus is different from the reproducing apparatus.

20. A reproducing apparatus, comprising:

a receiving unit that receives interruption information which is recorded on a recording medium and which represents where a reproduction of video data was interrupted during reproduction on a second reproduction apparatus, the interruption of the video data during reproduction on the second apparatus occurring in response to a user input; and

a reproducing unit that reproduces the video data, from where the reproduction of the video data was interrupted during reproduction on the second reproduction apparatus, based on the interruption information received by the receiving unit;

wherein the second reproducing apparatus is different from the reproducing apparatus.

21. A system for resuming reproduction, on a second reproducing apparatus, video data which was interrupted during reproduction on a first reproducing apparatus, the first reproducing apparatus being different from the second reproducing apparatus, the system comprising:

a recording unit operable to store interruption information on a recording medium, the interruption information representing where the first reproducing apparatus interrupts a reproduction of the video data, the interruption of the video data by the first reproducing apparatus occurring in response to a user input; and

a reproducing unit operable to read the interruption information from the recording medium;

wherein the second reproducing apparatus is operable to resume reproduction of the video data, from where the first reproducing apparatus interrupted a reproduction of the video data, based on the interruption information.
