Abstract

A system and computer program for evaluating in real-time streaming multimedia quality. The system including a multimedia server connected to a multimedia source and a remote client in communication with the multimedia server over a network. The multimedia server is configured to receive multimedia content from the multimedia source and to transmit the multimedia content as a multimedia stream. The multimedia stream includes a plurality of audio frames and a plurality of video frames. The remote client is configured to establish a multimedia session with the multimedia server, receive the multimedia stream via the multimedia session, monitor the media quality of the multimedia stream, and passively compute a subjective quality of the multimedia stream

Claims

1. A system for evaluating in real-time streaming multimedia quality, comprising

a multimedia server connected to a multimedia source, wherein the multimedia server is configured to receive multimedia content from the multimedia source and to transmit the multimedia content as a multimedia stream, wherein the multimedia stream includes a plurality of audio frames and a plurality of video frames;

a remote client in communication with the multimedia server over a network; and

wherein the remote client is configured to;

establish a multimedia session with the multimedia server;

receive the multimedia stream via the multimedia session;

monitor the media quality of the multimedia stream;

passively compute a subjective quality of the multimedia stream.

2. The system of claim 1, wherein the multimedia content comprises at least one selected from the group consisting of a live multimedia session, a stored multimedia session, a IPTV session, a voice over Internet protocol session, and a Telepresence session.

3. The system of claim 1, wherein passively computing the subjective quality comprises analyzing the impact of at least one of the group consisting of multimedia content, motion content and synchronization of the multimedia stream.

4. The system of claim 1, wherein the remote client is further configured to assess the multimodal cortex association distortion on the subjective quality to compute the impact of the relative deviation of the plurality of audio frames and the plurality of video frame.

5. The system of claim 1, wherein the system is independent of network infrastructure and protocols.

6. The system of claim 1, wherein the remote client is implemented along with a multimedia player.

7. The system of claim 1, wherein the subjective quality is computed using information theoretic metrics and network and media parameters.

8. The system of claim 1, wherein a theoretic distance between two measurements of the same frame is determined.

9. A computer program product embodied on a computer readable medium for evaluating in real-time streaming multimedia quality, wherein a multimedia server connected to a multimedia source is configured to receive multimedia content from the multimedia source and to transmit the multimedia content as a multimedia stream to a remote client over a network, the multimedia stream having a plurality of audio frames and a plurality of video frames, the computer program product comprising:

a first computer code for establishing a multimedia session with the multimedia server;

a second computer code for receiving the multimedia stream via the multimedia session;

a third computer code for monitoring the media quality of the multimedia stream; and

a fourth computer code for passively computing a subjective quality of the multimedia stream.

10. The computer program product of claim 9, wherein the multimedia content comprises at least one selected from the group consisting of a live multimedia session, a stored multimedia session, a IPTV session, a voice over Internet protocol session, and a Telepresence.

11. The computer program product of claim 9, wherein passively computing the subjective quality comprises analyzing the impact of at least one of the group consisting of multimedia content, motion content and synchronization of the multimedia stream.

12. The computer program product of claim 9, further comprising a fifth computer code for assessing the multimodal cortex association distortion on the subjective quality to compute the impact of the relative deviation of the plurality of audio frames and the plurality of video frame.

13. The computer program product of claim 9, wherein the computer program product operates independent of network infrastructure and protocols.

14. The computer program product of claim 9, wherein the remote client is implemented along with a multimedia player.

15. The computer program product of claim 9, wherein the subjective quality is computed using information theoretic metrics.

16. The computer program product of claim 9, wherein a theoretic distance between two measurements of the same frame is determined.
