VIDEO QUALITY MONITORING METHOD, DISTRIBUTION SERVER, AND CLIENT

摘要

In a video quality monitoring method by which video quality distributed by a system for performing video distribution from a distribution server to one or more clients through a network is monitored, the reference video that the distribution server distributes is compared with the deterioration video in which a scenario whose quality is deteriorated by the network is generated in a pseudo manner to measure a full-reference type of video quality index value. The value of the quality deterioration changed by a plurality of scenarios for each certain period and the characteristic data of the video quality index value corresponding to each of the scenarios are created and sent to each of the clients. Furthermore, each of the clients measures the quality deterioration value in the distribution video distributed from the network to calculate the video quality index value equivalent to the full-reference type of distribution video from the measured quality deterioration value and the characteristic data.
