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 for multimedia content delivery, comprising:

a first multimedia decoder responsive to a pause command;

a second multimedia decoder unresponsive to a pause command; and

a priority detector that determines if a data stream is a priority data stream before allowing the data stream to be processed by the second multimedia decoder instead of the first multimedia decoder, wherein the priority detector determines priority from a priority tag included in the data stream, and wherein when a pause command is received, processing by the second multimedia decoder of a priority data stream is unresponsive to the pause command.

2. The system of claim 1, wherein the priority detector determines if a priority data stream is associated with a recipient before allowing the bypassing of the pause command.

3. The system of claim 1, wherein the priority detector monitors a data stream for disruptions in transmission.

4. The system of claim 3, wherein the priority detector compares an embedded data rate to a received data rate to detect disruptions.

5. The system of claim 4, further comprising a disruption indicator for indicating when the priority detector detects a disruption of the received data rate.

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

7. The system of claim 6, wherein the system further includes a data acceptor that accepts interactive user feedback associated with the display updates when the system is paused.

8. The system of claim 1, wherein the data stream comprises a security data stream.

9. A method for content delivery, comprising:

providing a first processing path through a multimedia decoder that is responsive to a pause command;

providing a second processing path through a multimedia decoder that is unresponsive to a pause command;

determining, with a processor, a processing path based on a priority tag included in a received data stream when a pause command is set;

processing the data stream through the second processing path if the data stream is tagged as a priority data stream, wherein the multimedia decoder is unresponsive to a pause command; and

processing the data stream through the first processing path if the data stream is not tagged as a priority data stream.

10. The system of claim 9, further comprising:

determining if a priority data stream is associated with a recipient before allowing selective processing.

11. The method of claim 9 further comprising:

monitoring the content in the data stream for disruptions in transmission.

12. The method of claim 11, wherein the monitoring includes comparing an embedded content data rate to a received channel data rate to detect disruptions.

13. The method of claim 11 further comprising:

outputting a disruption indicator when a disruption of the received content data rate is detected.

14. The method of claim 9 further comprising:

selectively outputting display updates from the channel during a pause mode.

15. The method of claim 14 further comprising accepting interactive user feedback associated with the display updates during a pause mode.
