“…The average MOS score for each group of pictures is calculated, then the results are sorted from low to high MOS, and the MOS score for the GOP at the 10% point is taken as the quality measure. This, and another, weighted average measure is described in more detail in [3].…”

“…Earlier work [3] introduced a way giving a single value to the overall quality of a constant bitrate stream. The simplest way of generating an overall quality score would be to take the average MOS score for the individual frame.…”

“…By focussing on the perceptual quality of the video rather than the bitrate, we have shown in simulations [3] that we can deliver twice the amount of video at the equivalent perceptual quality over the same constrained network. This is possible because CBR encoded video is generally wasteful as the encoded bitrate has to be high enough to be able to encode the majority of the content at an acceptable quality.…”

A field trial of Quality driven Video Streaming is described and shows how we can achieve approximately a 40% reduction in byte volume for adaptive constant quality delivery compared to adaptive constant bitrate delivery while maintaining the equivalent overall quality. The trials were carried out over BT's broadband network. Video delivery; EQVS; Equitable quality video streaming; adaptive streaming; constant quality;

Video streaming has frequently been deployed using constant bit rate video encoding and transmission as these are easily implemented and network provisioning, although requiring admission control, is straightforward. However, it is sub-optimal for both the user, who experiences time varying quality, and the network operator, who cannot fully utilize the network during periods of low usage and is faced with admission control and session refusal at busy times. Instead we propose an equitable quality scheme in which the available network bandwidth is divided between the concurrent sessions so that the same quality is delivered in each. We show that we can increase average quality (Mean Opinion Score) by 0.74, or alternatively increase the number of sessions that can be supported at the same average overall quality by 100%.
