Abstract

A pausable system that processes multi-channel, multimedia content including a multimedia content delivery device having a priority detector for determining priority multimedia content and a decoder that can decode the priority content while the system is in a paused state. The system can also output an indicator if a priority multimedia content becomes disrupted based on a received rate compared to an embedded rate. The priority detector can also determine if the priority content is intended for a particular recipient before processing by the multimedia content delivery device.

Claims

1. A system, comprising:

a content delivery device that selectively processes content on a channel when the system is paused.

2. The system of claim 1, wherein the content delivery device comprises a first multimedia decoder responsive to a pause command and a second multimedia decoder unresponsive to a pause command.

3. The system of claim 1, wherein the content delivery device further comprises a priority detector.

4. The system of claim 3, wherein the priority detector determines if a priority channel is associated with a recipient before allowing the bypassing of the pause command.

5. The system of claim 3, wherein the priority detector monitors a content channel for disruptions in transmission.

6. The system of claim 5, wherein the priority detector compares an embedded content data rate to a received content data rate to detect disruptions.

7. The system of claim 6, further comprising a disruption indicator for indicating when the priority detector detects a disruption of the received content data rate.

8. The system of claim 1, wherein the system selectively outputs display updates from a decoded priority channel when the system is paused.

9. The system of claim 8, wherein the system further includes a data acceptor that accepts interactive user feedback associated with the display updates when the system is paused.

10. The system of claim 1, wherein the channel comprises a security data channel.

11. A method for receiving content, comprising the steps of

selectively processing multimedia content on a channel while in a pause mode.

12. The method of claim 11 further comprising the step of processing selected content on the channel through a separate processing path that is unresponsive to a pause command.

13. The method of claim 11 further comprising the step of determining a priority of the content on the channel to determine if it should be selectively processed.

14. The system of claim 13 further comprising the step of determining if a priority channel is associated with a recipient before allowing selective processing.

15. The method of claim 11 further comprising the step of monitoring the content on the channel for disruptions in transmission.

16. The method of claim 15, wherein the step of monitoring includes comparing an embedded content data rate to a received channel data rate to detect disruptions.

17. The method of claim 15 further comprising the step of outputting a disruption indicator when a disruption of the received content data rate is detected.

18. The method of claim 11 further comprising the step of selectively outputting display updates from the channel during a pause mode.

19. The method of claim 18 further comprising accepting interactive user feedback associated with the display updates during a pause mode.
