Abstract
The present invention is a system or method that facilitates smart decision makings at the client side for adaptive video streaming over a video delivery network by making use of perceptual video quality-of-experience predictions performed during the video preparation stage, at the video hosting or cache server side, or inside the video delivery network, and then transmitted to the client. Compared with prior art approaches of adaptive bitrate video streaming, the present invention can result in one or more of the following benefits: 1) save the overall bandwidth for the delivery of the video content without scarifying the client users' quality-of-experience; 2) create better overall visual quality-of-experience of the client users; 3) create smoother visual quality-of-experience of the client users; and 4) reduce the probability of rebuffering or stalling events at the client user side.
