Abstract:
1. A video quality monitoring method, comprising: a distribution server measuring a plurality of first video quality index values according to a full-reference method by comparing a video, distributed from the distribution server to a client through a network, with a degraded video, generated by causing a plurality of scenarios of quality degradation due to the network in the video in a pseudo manner; the distribution server creating characteristic data of a plurality of first quality degradation values, obtained by causing the quality degradation to vary with the scenarios at regular intervals, and the first video quality index values corresponding to the respective scenarios, and transmitting the characteristic data to the client; the client measuring a second quality degradation value in the video distributed through the network; and the client calculating a second video quality index value, equivalent to a value according to the full-reference method, of the distributed video from the measured second quality degradation value and the characteristic data.
