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 allocating greater bandwidth for transmission of the primary video.

Use of simultaneously received videos by a system to generate a quality of experience value

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.

A computer-implemented method, computer program product, and computing system is provided for decoding media streams. In an implementation, a method may include selecting a time window for monitoring discontinuities in a plurality of packets in a media transmission stream having a first time and a second time. The first time may indicate a beginning of the time window and the second time may indicate an end of the time window. The method may also include determining the number of discontinuities in the plurality of packets at the first time at a network node. The method may also include determining the number of discontinuities in the plurality of packets at the second time at the network node. The method may also include determining the number of discontinuities in the plurality of packets within the time window. The method may also include comparing the number of discontinuities within the time widow to a plurality of predefined discontinuities threshold values. The method may also include decoding one or more of the plurality of packets in the media stream based upon, at least in part, the comparison of the number of discontinuities within the time widow to the plurality of predefined discontinuities threshold values.

Decoding media streams within thresholds

A first instance of a reference video is stored. A primary video and a second instance of the reference video are simultaneously received. At least one quality of experience value that infers a perceptual quality of the primary video as received by a system is generated by comparing the first instance of the reference video to the second instance of the reference video on a pixel-by-pixel, frame-by-frame, basis and determining 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.

A computer-implemented method, computer program product, and computing system is provided for quality of experience for media transmissions. In an implementation, a method may include defining a lower media stream discontinuity threshold. The method may also include evaluating a media stream discontinuity rate associated with a portion of a media stream. When the media stream discontinuity rate associated with the portion of the media stream is greater than the lower media stream discontinuity threshold, the method may further include determining a quality of experience associated with the portion of the media stream based upon, at least in part, a payload associated with the portion of the media stream.

Managing quality of experience for media transmissions

A computer-implemented method, computer program product, and computing system for receiving one or more transmitted frame identifiers that are mathematical representations of one or more transmitted video frames included within a multi-frame video. One or more video frames included within the multi-frame video are received, thus defining one or more received video frames. A mathematical representation of each of the one or more received video frames is generated, thus defining one or more received frame identifiers. The one or more received frame identifiers are compared to the one or more transmitted frame identifiers to determine a level of similarity between the one or more received video frames and the one or more transmitted video frames.
