Abstract

The present invention relates to a recording medium including video, audio and graphics information stored in separate sets of data packets and a method for creating the same. The graphic information can be superimposed on the video information during playback of the recording media. The graphic information can include text or images. The text has a translucent background and the images may be translucent in whole or in part.

Claims

1. A recording medium comprising:

a first set of data packets on which video data is recorded;

a second set of data packets on which audio data is recorded; and

a third set of data packets on which graphic data is recorded;

wherein;

said graphic data is superimposed on said video data during display, and

said graphic data is selected from the group consisting of;

text with a translucent background and an image, wherein said image is selected from the group consisting of an image translucent in whole and an image translucent in part.

2. The recording medium of claim 1 for use with a playback device wherein said graphic data recorded in said third set of data packets is selectively displayed by a user of said playback device.

3. The recording medium of claim 1 wherein said graphic data is stored in graphic data packets as a run-length compressed image file.

4. The recording medium of claim 1 wherein said first, second and third sets of data packets are segmented into a plurality of frames, whereby selected ones of said plurality of frames comprise video data, audio data and graphic data for reproduction during a set interval of time.

5. The recording medium of claim 4 wherein said set interval of time is selected from the group consisting of 1/24 second, 1/25 second and 1/30 second.

6. The recording medium of any one of claims 1 through 5 wherein said recording medium comprises a DVD disc.

7. The recording medium of any one of claims 1 through 5 wherein said translucent background is textured.

8. A method for generating graphic data for use in a recording medium comprising a first set of data packets on which video data is recorded, a second set of data packets on which audio data is recorded and a third set of data packets on which said graphic data is recorded, said method comprising the steps of:

selecting an input data file;

creating a blank bit map;

determining whether said input data file includes text and text locations, background and background locations and placing said text and said background at text locations and said background locations, respectively, on said bit map;

determining whether said input data file includes an image and an image location and placing said image at said image location on said bit map; and

transferring said bit map to said third set of data packets.

9. The method of claim 8 wherein said transferring step comprises the sub-steps of:

storing said bit map in output files located in a computer including a disk drive; and

placing said bit map stored in said output files onto said disk for importation onto said recording medium.

10. The method of claim 8 wherein said recording medium is for use with a playback device and said graphic data recorded in said third set of data packets is selectively displayed by a user of said playback device.

11. The method of claim 8 wherein said graphic data is stored in graphic data packets as a run-length compressed image file.

12. The method of claim 8 wherein said first, second and third sets of data packets are segmented into a plurality of frames, whereby selected ones of said plurality of frames comprise video data, audio data and graphic data for reproduction during a set interval of time.

13. The method of claim 12 wherein said set interval of time is selected from the group consisting of 1/24 second, 1/25 second and 1/30 second.

14. The method of any one of claims 11 through 13 wherein said recording medium comprises a DVD disc.

15. The method of any one of claims 11 through 13 wherein said translucent background is textured.

16. A DVD disc for use with a playback device by a user comprising:

a first set of data packets on which video data is recorded;

a second set of data packets on which audio data is recorded; and

a third set of data packets on which graphic data is recorded;

wherein;

said graphic data is superimposed on said video data during display,

said graphic data is selected from the group consisting of;

text with a translucent background and an image, wherein said image is selected from the group consisting of an image translucent in whole and an image translucent in part, said graphic data recorded in said third set of data packets is selectively displayed by said user of said playback device,

said graphic data is stored in graphic data packets as a run-length compressed image file, and

said first, second and third sets of data packets are segmented into a plurality of frames, whereby selected ones of said plurality of frames comprise video data, audio data and graphic data for reproduction during a set interval of time.
