Abstract

A method and apparatus for loading multiple animated images on a Web page during browsing over a network with limited bandwidth. The method comprising the steps of: (1) retrieving hypertext objects containing a Java applet from servers over a network into a browser utilizing a Java engine for running Java applets; (2) displaying a default image and default image effects by the Java applet; and (3) the Java applet retrieving a target image series comprising a series of related images from the server and loading the target image series one image at a time with screen transition effects in between each image so that a speed of the screen transition effects is set to finish when a next image in the image series is retrieved over the network of limited bandwidth and prepared for loading by said Java applet, thereby making the speed of the screen transition effects proportional to a time required to retrieved the next image in the image series.

In another embodiment, an apparatus and computer readable medium carries out the method above.

Claims

1. An information processing system comprising:

a browser for retrieving hypertext objects from servers over a network, wherein said network has a limited bandwidth associated therewith;

said browser including a Java engine for running Java applets;

a hypertext means responsive to activation of a hypertext link, for retrieving from said server a hypertext object containing a Java applet,

said Java applet loading an animation applet from said server having a default image and default image animation effects for display on said browser; and

said Java applet requesting a target image series comprising a series of related images from said server and loading said target image series one image at a time with screen transition effects in between each image so that a speed of said screen transition effects is set to finish when a next image in said image series is retrieved over said network of limited bandwidth and prepared for loading by said Java applet, thereby making said speed of said screen transition effects proportional to a time required to retrieved said next image in said image series.

2. The information processing system of claim 1 wherein said screen transition effects is selected from a group consisting of fades, dissolves, vertical shutters, horizontal shutters.

3. The information processing system of claim 1 further comprising a mouse pointer wherein a user may selectively click on said animation applet so as to cause a new browser window to be launched displaying informational content related to said animation applet.

4. The information processing system of claim 1 further comprising:

said browser for retrieving hypertext objects from servers over a network;

said browsers including a Java engine for running Java applets and said browser supporting separate HTML frames for displaying images.

5. The information processing system of claim 1 further comprising:

said Java applet being reentrant so as to support coterminous animation effects for one or more images displayed on said browser.

6. A method for loading multiple animated images comprising the steps of:

retrieving hypertext objects containing a Java applet from servers over a network with a limited bandwidth associated therewith, into a browser utilizing a Java engine for running Java applets;

displaying a default image and default image effects by said Java applet; and

said Java applet retrieving a target image series comprising a series of related images from said server and loading said target image series one image at a time with screen transition effects in between each image so that a speed of said screen transition effects is set to finish when a next image in said image series is retrieved over said network of limited bandwidth and prepared for loading by said Java applet, thereby making said speed of said screen transition effects proportional to a time required to retrieved said next image in said image series.

7. The method for loading multiple animated images in claim 6 wherein said screen transition effects is selected from a group consisting of fades, dissolves, vertical shutters, horizontal shutters.

8. The method for loading multiple animated images in claim 6 wherein a user may selectively click on said animation applet so as to cause a new browser window to be launched displaying informational content related to said animation applet.

9. The method for loading multiple animated images in claim 6 wherein said browser utilizing a Java engine for running Java applets, said browser supporting separate HTML frames for displaying images.

10. The method for loading multiple animated image in claim 6 wherein said Java applet being reentrant so as to support coterminous animation effects for one or more images displayed on said browser.

11. A computer-readable storage medium containing instructions for loading multiple animated images by:

program instruction means for retrieving hypertext objects containing a Java applet from servers over a network with a limited bandwidth associated therewith, into a browser utilizing a Java engine for running Java applets;

said Java applet contain a first program instruction means for displaying a default image and default image effects by said Java applet; and

said Java applet contain a second program instruction means for retrieving a target image series comprising a series of related images from said server and loading said target image series one image at a time with screen transition effects in between each image so that a speed of said screen transition effects is set to finish when a next image in said image series is retrieved over said network of limited bandwidth and prepared for loading by said Java applet, thereby making said speed of said screen transition effects proportional to a time required to retrieved said next image in said image series.

12. The computer-readable storage medium of claim 11 containing instructions for loading multiple animated images wherein said screen transition effects is selected from a group consisting of fades, dissolves, vertical shutters, horizontal shutters.

13. The computer-readable storage medium of claim 11 containing instructions for loading multiple animated images wherein a user may selectively click on said animation applet so as to cause a new browser window to be launched displaying informational content related to said animation applet.

14. The computer-readable storage medium of claim 11 containing instructions for loading multiple animated images wherein said browser utilizing a Java engine for running Java applets, said browser supporting separate HTML frames for displaying images.

15. The computer-readable storage medium of claim 11 containing instructions for loading multiple animated images wherein said Java applet being reentrant so as to support coterminous animation effects for one or more images displayed on said browser.
