Abstract

An embodiment of the present invention allows a user to maintain the display of a video frame containing one or more interactive links while also maintaining access to the links. Thus allowing the user to select and examine any desired links at his own pace. For one embodiment, the display of a video frame is maintained by interrupting the refreshing of the frame buffer and the interactive link stream. Interrupting both the frame buffer refresh and the interactive link stream refresh results in the frame being “frozen” along with its associated links. For one embodiment, pressing a button on a control device effects the interruption of the frame buffer refresh and the interactive link refresh. The button may toggle to resume the video display. Alternatively, or additionally, the video display may resume if no action is taken in regard to the interactive links within an specified time.

Claims

1. A method comprising:

computing the number of interactive links associated with a frame of a live video presentation;

while displaying the frame of the live video presentation, automatically storing for later use the frame of the live video presentation when the number of interactive links associated with the frame of the live video presentation is greater than a number of interactive links which can be reviewed and assessed by a user in real-time;

maintaining the display of the automatically stored frame of the live video presentation, the automatically stored frame having associated therewith at least one interactive link; and

maintaining access to the at least one interactive link associated with the automatically stored frame such that a user may review and access the at least one interactive link.

2. The method of claim 1, wherein displaying the automatically stored frame of the live video presentation, maintaining the display of the automatically stored frame and maintaining access to the at least one interactive link are done in response to a user action.

3. The method of claim 2, wherein the user action is depressing an activation button on a control device.

4. The method of claim 3 further comprising:

depressing a deactivation button to stop displaying the automatically stored frame of the live video presentation and return to the live video presentation.

5. A method comprising:

computing the number of interactive links associated with a frame of a live video presentation;

determining that the number of interactive links associated with the frame of the live video presentation is greater than a number of interactive links which can be reviewed and accessed by a user in real-time and;

automatically interrupting a frame buffer such that the live video presentation is interrupted and a display of the frame of the live video presentation is maintained, the frame having associated therewith at least one interactive link; and

automatically interrupting an interactive link stream such that access to the at least one interactive link associated with the frame is maintained.

6. The method of claim 5 further comprising:

depressing a deactivation button to stop displaying the frame of the live video presentation and return to the live video presentation.

7. The method of claim 5, wherein the frame and the at least one interactive link are stored for later use such that access to the at least one interactive link is maintained.

8. One or more computer-readable media containing instructions that, when executed by a processor, cause the processor to perform a method, the method comprising:

computing the number of interactive links associated with a frame of a live video presentation;

while displaying the frame of the live video presentation, automatically storing for later use the frame of the live video presentation when the number of interactive links associated with the frame of the live video presentation is greater than a number of interactive links which can be reviewed and assessed by a user in real-time;

maintaining the display of the automatically stored frame of the live video presentation, the automatically stored frame having associated therewith at least one interactive link; and

maintaining access to the at least one interactive link associated with the automatically stored frame such that a user may review and access the at least one interactive link.

9. The one or more computer-readable media of claim 8, wherein displaying the automatically stored frame of the live video presentation, maintaining the display of the automatically stored frame and maintaining access to the at least one interactive link are done in response to a user action.

10. The one or more computer-readable media of claim 9, wherein the user action is depressing an activation button on a control device.

11. The one or more computer-readable media of claim 10 further comprising:

depressing a deactivation button to stop displaying the automatically stored frame of a live video presentation and return to the live video presentation.

12. One or more computer-readable media storing instructions that, when executed by a processor, cause the processor to perform a method, the method comprising:

computing the number of interactive links associated with a frame of a live video presentation;

determining that the number of interactive links associated with the frame of the live video presentation is greater than a number of interactive links which can be reviewed and accessed by a user in real-time and;

automatically interrupting a frame buffer such that a live video presentation is interrupted and a display of the frame of the live video presentation is maintained, the frame having associated therewith at least one interactive link; and

automatically interrupting an interactive link stream such that access to the at least one interactive link associated with the frame is maintained.

13. The one or more computer-readable media of claim 12, wherein the automatically interrupted frame and the at least one interactive link are stored for later use such that access to the at least one interactive link is maintained.

14. An apparatus comprising:

a processor having a memory coupled thereto, the memory having stored thereon executable instructions which, when executed by the processor, cause the processor to compute the number of interactive links associated with a frame of a live video presentation, while displaying the frame of the live video presentation automatically store for later use a frame of the live video presentation when the number of interactive links associated with the frame of the live video presentation is greater than the number of interactive links which can be reviewed and accessed by a user in real-time, display the automatically stored frame of the live video presentation, maintain the display of the automatically stored frame of the live video presentation, the automatically stored frame having associated therewith at least one interactive link, and maintain access to the at least one interactive link associated with the automatically stored frame such that a user may review and access the at least one interactive link.

15. The apparatus of claim 14, further comprising;

a control device, the control device having an activation mechanism to initiate execution of the executable instructions.

16. The apparatus of claim 15, wherein the control device has a deactivation mechanism to stop displaying the automatically stored frame of the live video presentation and return to the live video presentation.

17. A system comprising:

a video presentation device, the video presentation device capable of displaying a live video presentation; and

a control device to compute the number of interactive links associated with a frame of the live video presentation, while displaying the frame of the live video presentation on the video presentation device automatically store for later use the frame of the live video presentation when the number of interactive links associated with the frame of the live video presentation is greater than a number of interactive links which can be reviewed and accessed by a user in real-time, display the automatically stored frame of the live video presentation, maintain the display of the automatically stored frame of the live video presentation, the automatically stored frame having associated therewith at least one interactive link, and maintain access to the at least one interactive link associated with the automatically stored frame such that a user may review and access the at least one interactive link.
