Abstract

A system and method for use as an authoring system for the development of CD-ROM products containing interleaved digitized audio and graphic images and other information which may be read and displayed or played under control of a computer. The graphic images and other computer information are stored in a file on the CD-ROM such that when the CD-ROM is accessed by a user, the graphic images and other computer information are displayed and made available to the user synchronously with the playing of the audio information. Combinations of several streams of audio and graphic/computer information can be interleaved into the same file. The system enables an editor to combine various audio files in synchronization with multiple graphic images into a single file which can then be stored on a CD-ROM. Other computer information can also be interleaved with the graphics and audio to allow for control over the playback at runtime. The graphics and other computer information are referred to herein collectively as "resources." The system allows the temporal and spatial placement of the resources on a run time computer screen to be displayed at a time and position which is specified by the editor when authoring.

Claims

1. A system for use as an authoring system for the development of CD-ROM products containing interleaved digitized audio and graphic images and other information for reading, and displaying or playing under control of a computer comprising:

a) means for converting a plurality of analog image and audio data to digitized image data and digitized audio data respectively;

b) means for creating and storing as separate files said digitized image and digitized audio data, said separate files corresponding to said plurality of analog image and audio data;

c) means for creating a single file for storage as CD-ROM data containing information from said separate files of digitized image and digitized audio data such that upon playback of said single file, said digitized audio data as played back is synchronized in a predetermined manner with said digitized image data as played back;

d) means for converting said created single file into packets of information to be stored on a CD-ROM.

2. The system defined by claim 1 wherein said means for creating a single file comprises:

a) means for displaying a representation of an empty band of information which is to contain representations of digitized audio and digitized image data;

b) means for allocating space within said empty band for containing a representation of a spine of said digitized audio data and at least one spine of said digitized image data;

c) means for loading a file of said digitized audio data for placing into said single file, determining the amount of time needed to play said loaded file of digitized audio data and indicating in said allocated spine of digitized audio data a representation of said determined play time;

d) means for determining the amount of time needed to display an image of a predetermined size and indicating in said allocated at least one spine of digitized image data a representation of said determined display time;

e) means for loading at least one file of said digitized image data for placing into said single file;

f) means for generating said single file from said loaded file of digitized audio data and said at least one file of loaded digitized image data wherein said digitized audio data and said digitized image data are interleaved in a predetermined manner.

3. The system defined by claim 2 further comprising means for playing back said generated single file.

4. The system defined by claim 2 further comprising means for positioning and repositioning a location at which said digitized image data is to be displayed and for sizing and resizing the area to be used by said digitized image data.

5. The system defined by claim 2 further comprising means for adding a display effect to the digitized image data to be displayed during playback.

6. The system defined by claim 5 wherein said display effect is one of down wipe, up wipe, left wipe, right wipe, dissolve and fade.

7. The system defined by claim 2 further comprising means for providing a size translation to the digitized image data to be displayed during playback.

8. The system defined by claim 7 wherein the size translation is one of 1:

2 expansion, 2;

1 compression, 5;

4 compression and 6;

5 compression.

9. A method for use as an authoring system for the development of CD-ROM products containing interleaved digitized audio and graphic images and other information for reading and displaying or playing under control of a computer comprising the steps of:

a) converting a plurality of analog image and audio data to digitized image data and digitized audio data respectively;

b) creating and storing as separate files said digitized image data and said digitized audio data, said separate files corresponding to said plurality of analog image and audio data;

c) creating a single file for storage as CD-ROM data containing information from said separate files of digitized analog image and digitized audio data such that upon playback of said single file, said digitized audio data as played back is synchronized in a predetermined manner with said digitized image data as played back;

d) converting said generated single file into packets of information to be stored on a CD-ROM.

10. The method defined by claim 9 wherein said method step for creating a single file comprises the steps of:

a) displaying a representation of an empty band of information which is to contain representations of digitized audio and digitized image data;

b) allocating space within said empty band for containing a representation of a spine of said digitized audio data and at least one spine of said digitized image data;

c) loading a file of said digitized audio data for placing into said single file, determining the amount of time needed to play said loaded file of digitized audio data and indicating in said allocated spine of digitized audio data a representation of said determined play time;

d) determining the amount of time needed to display an image of a predetermined size and indicating in said allocated at least one spine of digitized image data a representation of said determined display time;

e) loading at least one file of said digitized image data for placing into said single file;

f) generating said single file from said loaded file of digitized audio data and said at least one file of loaded digitized image data wherein said digitized audio data and said digitized image data are interleaved in a predetermined manner.

11. The method defined by claim 10 further comprising the step of playing back said generated single file.

12. The method defined by claim 10 further comprising the step of positioning and repositioning a location at which said digitized image data is to be displayed and for sizing and resizing the area to be used by said digitized image data.

13. The method defined by claim 10 further comprising the step of adding a display effect to the digitized image data to be displayed during playback.

14. The method defined by claim 13 wherein said display effect is one of down wipe, up wipe, left wipe, right wipe, dissolve and fade.

15. The method defined by claim 10 further comprising the step of providing a size translation to the digitized image data to be displayed during playback.

16. The method defined by claim 15 wherein the size translation is one of 1:

2 expansion, 2;

1 compression, 5;

4 compression and 6;

5 compression.

17. The method defined by claim 9 further comprising the step of positioning and repositioning a location at which said digitized image data is to be displayed and for sizing and resizing the area to be used by said digitized image data.

18. The method defined by claim 9 further comprising the step of adding a display effect to the digitized image data to be displayed during playback.

19. The method defined by claim 18 wherein said display effect is one of down wipe, up wipe, left wipe, right wipe, dissolve and fade.

20. The method defined by claim 9 further comprising the step of providing a size translation to the digitized image data to be displayed during playback.

21. The method defined by claim 20 wherein the size translation is one of 1:

2 expansion, 2;

1 compression, 5;

4 compression and 6;

5 compression.
