Abstract

A method and apparatus providing display of content and automatic pause of the display. The method and apparatus exists in a client device and/or ahead-end or network operator. Event are assigned a relative priority based on event type, originator and the type of current display so that a variable response level ranging from a required viewer action to the viewer completely ignoring an event is provided.

Claims

1. A method for automatically pausing the display of content and processing events at a client device, said content being provided by a server at a head-end operator, broadcaster, web content provider or network operator, said method comprising:

displaying content on a client device;

detecting an event at the client device during the display of the content;

assigning a priority to the detected event, said priority being selected from a plurality of priorities which may be assigned to an event;

pausing display of the content and recording the content while the display is paused, wherein said pausing is automatically performed in response to determining said priority is relatively high;

continuing display of the content, in response to determining said priority is relatively low;

providing a viewer discernable notification of the detected event; and

removing the viewer discernable notification of the detected event, in response to detecting said priority is relatively low and a timeout for acknowledgement of said event has expired.

2. The method of claim 1, wherein said priority is based at least in part on either (1) the subject matter of the content currently being displayed, or (2) a viewer profile.

3. The method of claim 1 further comprising:

resuming display of the paused content, in response to detecting an acknowledgement of said event from the viewer.

4. The method of claim 3 wherein resuming display of the paused content comprises replaying the recorded content at an accelerated rate until the playback of recorded content synchronizes with the provided content so that the display switches back to display of the provided content.

5. The method of claim 4 wherein the accelerated playback rate is automatically determined based on the duration of the pause and the duration of the content remaining so that the content display ends at the same time it would have ended without a paused interruption in the display.

6. The method of claim 1 wherein the step of assigning a priority further comprises either:

identifying an originator of the event, identifying a viewer preference for the originator, and assigning a priority based on the viewer preference with regard to the originator;

or

identifying an event type, identifying a viewer preference for the event type, and assigning a priority based on the viewer preference with regard to the event type.

7. The method of claim 6, wherein the step of assigning a priority further comprises applying an interruption rule based on the current content displayed.

8. The method of claim 1, further comprising:

placing data corresponding to the detected event in a pending queue responsive to said timeout.

9. The method of claim 8, further comprising utilizing the data stored in the pending queue to retry the detected event, wherein said retrying comprising providing an additional viewer discernable notification of the detected event.

10. The method of claim 9, wherein said viewer discernable notification comprises an audible and/or visible notification;

and wherein said retrying further comprises providing said audible and/or visible notification with an increased intensity.

11. An apparatus for automatically pausing the display of content provided by a server at a head-end operator, broadcaster, web content provider or network operator and processing incoming events, said apparatus comprising:

a display device for displaying content;

an interface for receiving an event during the display of the content;

a storage device for storing received content; and

a processing unit configured to;

assign a priority to the received event, said priority being selected from a plurality of priorities which may be assigned to an event;

automatically pause display of the content and record the content on the storage device while the display is paused, in response to determining said priority is relatively high with respect to said plurality of priorities

continue display of the content, in response to determining said priority is relatively low with respect to said plurality of priorities;

provide a viewer discernable notification of the event; and

remove the viewer discernable notification of the detected event, in response to detecting said priority is relatively low and a timeout for acknowledgement of said event has expired.

12. The apparatus of claim 11 wherein said processing unit is configured to assign said priority based at least in part on either (1) the subject matter of the content currently being displayed, or (2) a viewer profile.

13. The apparatus of claim 12 wherein said processing unit is further configured to resume display of the paused content which is recorded on the storage device, in response to detecting an acknowledgement of said event from the viewer.

14. The apparatus of claim 13 wherein the processing unit is further configured to replay the recorded content at an accelerated rate until the playback of the recorded content synchronizes with the provided content so that the display switches back to display of the provided content.

15. The apparatus of claim 14 further wherein said processing unit is configured to automatically determine the accelerated playback rate based in part upon the duration of the pause and the duration of the display content remaining.

16. The apparatus of claim 15 further comprising:

a data structure for identifying an originator of the event and a viewer preference for the originator; and

a processor for examining the data structure identifying originator of the event, the viewer preference for the originator and assigning a priority based on the viewer preference with regard to the originator.

17. The apparatus of claim 11, wherein said processing unit is further configured to place the event in a pending queue responsive to the timeout.

18. The apparatus of claim 17, wherein the processing unit is configured to retry the event in the pending queue by providing an additional viewer discernable notification of the event.

19. The apparatus of claim 18, wherein said viewer discernable notification comprises an audible and/or visible notification;

and wherein said retrying further comprises providing said audible and/or visible notification with an increased intensity.

20. A computer readable storage medium comprising instructions which when executed are operable to:

display content provided by a server on a client device;

detect an event at the client device during the display of the content;

assign a priority to the detected event, said priority being selected from a plurality of priorities which may be assigned to an event;

pause display of the content and record the content while the display is paused, wherein said pausing is automatically performed in response to determining said priority is relatively high;

continue display of the content, in response to determining said priority is relatively low;

provide a viewer discernable notification of the detected event; and

remove the viewer discernable notification of the detected event, in response to detecting said priority is relatively low and a timeout for acknowledgement of said event has expired.
