Abstract

A primary video and a second instance of a reference video can be simultaneously transmitted to a system through at least a first node of a communication network, the second instance of the reference video configured to be compared to a first instance of the reference video stored by the system to generate at least one quality of experience (QoE) value that infers a perceptual quality of the primary video as received by the system. The QoE value can be received from the system. A determination can be made as to whether the QoE value is less than a threshold value. Responsive to determining that the QoE value is less than the threshold value, the perceptual quality of the primary video can be improved by re-routing transmission of the primary video to the system.

Claims

21. A method, comprising:

simultaneously transmitting a primary video and a second instance of a reference video to a system through at least a first node of a communication network, the second instance of the reference video configured to be compared to a first instance of the reference video stored by the system to generate at least one quality of experience value that infers a perceptual quality of the primary video as received by the system;

receiving from the system the at least one quality of experience value that infers the perceptual quality of the primary video as received by the system;

determining whether the at least one quality of experience value is less than a threshold value; and

responsive to determining that the at least one quality of experience value is less than the threshold value, improving the perceptual quality of the primary video by re-routing transmission of the primary video to the system.

22. The method of claim 21, wherein the primary video is re-routed to be transmitted through at least a second node of the communication network in lieu of being transmitted through the first node of the communication network.

23. The method of claim 22, wherein the second node of the communication network provides greater transmission bandwidth than the first node of the communication network.

24. The method of claim 21, further comprising:

responsive to determining that the at least one quality of experience value is less than the threshold value, improving the perceptual quality of the primary video by implementing an error protection scheme.

25. The method of claim 21, further comprising:

responsive to determining that the at least one quality of experience value is less than the threshold value, improving the perceptual quality of the primary video by changing an error protection scheme.

26. The method of claim 21, wherein:

the second instance of the reference video is compared to the first instance of the reference video on a pixel-by-pixel, frame-by-frame, basis to determine whether each pixel and each frame contained in the first instance of the reference video are contained in the second instance of the reference video.

27. The method of claim 21, wherein:

the second instance of the reference video is repeated by looping the second instance of the reference video in a data stream.
