Abstract

A system for processing data stream content in a multi-channel broadcast multimedia system including a packet processor having an input control having a filter module for detecting at least one priority data stream from an input data stream, and an output control including a format module for displaying the priority data streams in real-time. The system can include an alarm detector for checking a rate of the priority data stream and issuing an alarm in the event of an alarm condition of the priority data stream.

Claims

1. A system for processing an input data stream content in a multi-channel broadcast multimedia system, the system comprising:

a packet processor having

an input control for detecting at least one priority data stream in the input data stream; and

an output control including;

a format module for formatting the priority data stream for display in real-time; and

an alarm detector for checking a rate of the priority data stream and issuing an alarm in the event of a discontinuous packet stream of the priority data stream.

2. The system of claim 1, wherein the at least one priority data stream is representative of data which is designated as being desired to be displayed in real time at all times in the multimedia system.

3. The system of claim 1, wherein the output control includes a buffer for storing the detected at least one priority data stream.

4. The system of claim 1, wherein the output control includes a multiplexer for mixing the at least one priority data stream with non-priority data streams.

5. The system of claim 1, wherein the input control includes an outgoing timestamp counter configured for time-stamping the priority data with an outgoing timestamp value.

6. The system of claim 1, wherein the input control includes an incoming timestamp counter configured for time-stamping non-priority data with an incoming timestamp value.

7. The system of claim 1, wherein the input data stream includes non-priority data streams.

8. The system of claim 6, wherein the format module is configured for displaying the at least one priority data stream in real-time contemporaneously with the non-priority data streams.

9. The system of claim 1, wherein the output control includes an alarm data compiler for collecting alarm data comprising data rate information of the priority data stream and outputting the alarm data to the alarm detector.

10. The system of claim 1, wherein the packet processor is configured for receiving data streams from a plurality of data sources including satellite tuners, internet inputs, local camera inputs, and cable tuners.

11. The system of claim 7, wherein the packet processor includes a memory for storing said non-priority data streams.

12. A method for processing data stream content in a multi-channel broadcast multimedia system, comprising the steps of:

detecting at least one priority data stream from an input data stream;

displaying the priority data streams in real-time;

checking a rate of the priority data stream; and

issuing an alarm in the event of a discontinuous packet stream of the priority data stream.

13. The method of claim 12, wherein the at least one priority data stream is representative of data which is designated as being desired to be displayed in real time at all times in the multimedia system.

14. The method of claim 12, further comprising the step of storing the detected at least one priority data stream in a buffer.

15. The method of claim 12, further comprising the step of mixing the at least one priority data stream with non-priority data streams.

16. The method of claim 12, further comprising the step of time-stamping the priority data with an outgoing timestamp value.

17. The method of claim 12, further comprising the step of time-stamping non-priority data with an incoming timestamp value.

18. The method of claim 12, wherein the input data stream includes non-priority data streams.

19. The method of claim 16, further comprising the step of displaying the at least one priority data stream in real-time contemporaneously with the non-priority data streams.

20. The method of claim 12, further comprising the step of collecting alarm data comprising data rate information of the priority data stream.

21. The method of claim 18, further comprising the step of storing said non-priority data streams in a memory.
