Abstract

Claims (50)

1. A computer-implementable method comprising:

receiving a video stream of image frames;

accessing information indicative of changes in one or more portions of the video stream;

generating a video stream display for a video display device, wherein the video stream display includes:

the video stream; and

an overlay indicating the one or more portions of the video stream wherein the changes occur; and

generating a temporal change indicator to the video display device, indicating temporal portions of the video stream in which changes occur within the video stream;

wherein the information indicative of changes comprises pixel information received from a browser plugin and wherein the pixel information is indicative of changes occurring in one or more pixels between two successive image frames of the video stream display;

wherein the temporal change indicator indicates a percentage of pixels that change to between the two successive image frames of the video stream versus a time associated with the video stream;

wherein the percentage of pixels that change comprises a percentage of pixels within a particular area of the video stream that changed during a particular period of time.

2. The method of claim 1 , wherein the information indicative of changes in one or more portions of the video stream comprises information indicative of one or more areas of the video stream that have changed within a predetermined number of trailing image frames of the video stream relative to a currently displayed image frame of the video stream.

3. The method of claim 1 , wherein the information indicative of changes in one or more portions of the video stream comprises information indicative of one or more areas of the video stream that have changed within a predetermined trailing period of time of the video stream relative to a currently displayed image frame of the video stream.

4. The method of claim 1 , wherein the overlay is transparent.

5. The method of claim 1 , wherein generating the video stream display comprises generating the overlay substantially contemporaneously as to when changes to the video stream occur.

6. The method of claim 1 , wherein generating the video stream display comprises generating overlay over an area of the video stream for a period of time prior to when changes occur in such area.

7. The method of claim 1 , wherein generating the video stream display comprises generating overlay over an area of the video stream for a period of time after changes occur in such area.

8. The method of claim 1 , wherein generating the video stream display comprises generating overlay with a minimum size independent of an area of the video stream in which changes occur.

9. A computer-implementable method comprising:

receiving a video stream of image frames;

accessing information indicative of changes in one or more portions of the video stream; and

generating a video stream display for a video display device wherein the video stream display includes:

the video stream; and

presenting a temporal change indicator indicating temporal portions of the video stream in which changes occur within the video stream;

wherein the information indicative of changes comprises pixel information received from a browser plugin and wherein the pixel information is indicative of changes occurring in one or more pixels between two successive image frames of the video stream; and

wherein the temporal change indicator indicates a percentage of pixels that change between two successive image frames of the video stream versus a time associated with the video stream and wherein the percentage of pixels that change comprises a percentage of pixels within an area of the video stream that changed during a particular period of time.

10. A non-transitory, computer-readable storage medium embodying computer program code, the computer program code comprising computer executable instructions configured for:

receiving a video stream of image frames;

accessing information indicative of changes in one or more portions of the video stream; and

generating a video stream display for a video display device, wherein the video stream display includes:

the video stream;

an overlay indicating the one or more portions of the video stream wherein the changes occur; and

a temporal change indicator indicating temporal portions of the video stream in which changes occur within the video stream;

wherein the information indicative of changes comprises pixel information received from a browser plugin and wherein the pixel information is indicative of changes occurring in one or more pixels between two successive image frames of the video stream;

wherein the temporal change indicator indicates a percentage of pixels that change to between two successive image frames of the video stream versus a time associated with the video stream;

wherein the percentage of pixels that change comprises a percentage of pixels within an area of the video stream that changed during a particular period of time.

11. The storage medium of claim 10 , wherein the information indicative of changes in one or more portions of the video stream comprises information indicative of one or more areas of the video stream that have changed within a predetermined number of trailing image frames of the video stream relative to a currently displayed image frame of the video stream.

12. The storage medium of claim 10 , wherein the information indicative of changes in one or more portions of the video stream comprises the information indicative of one or more areas of the video stream that have changed within a predetermined trailing period of time of the video stream relative to a currently displayed image frame of the video stream.

13. The storage medium of claim 10 , wherein the overlay is transparent.

14. The storage medium of claim 10 , wherein generating the video stream display comprises generating the overlay substantially contemporaneously as to when changes to the video stream occur.

15. The storage medium of claim 10 , wherein generating the video stream display comprises generating the overlay over an area of the video stream for a period of time prior to when changes occur in such area.

16. The storage medium of claim 10 , wherein generating the video stream display includes generating the overlay over an area of the video stream for a period of time after changes occur in such area.

17. The storage medium of claim 10 , wherein generating the video stream display includes generating the overlay with a minimum size independent of an area of the video stream in which changes occur.

18. A non-transitory, computer-readable storage medium embodying computer program code, the computer program code comprising computer executable instructions configured for:

receiving a video stream of image frames;

accessing information indicative of changes in one or more portions of the video stream; and

generating a video stream display for a video display device wherein the video stream display includes:

the video stream; and

a temporal change indicator indicating temporal portions of the video stream in which changes occur within the video stream;

wherein the information indicative of changes comprises pixel information received from a browser plugin and wherein the pixel information is indicative of changes occurring in one or more pixels between two successive image frames of the video stream; and

wherein the temporal change indicator indicates a percentage of pixels that change between two successive image frames of the video stream versus a time associated with the video stream and wherein the percentage of pixels that change comprises a percentage of pixels within an area of the video stream that changed during a particular period of time.
