Abstract

The embodiment of the invention discloses a method and a device for evaluating the quality of a video, which relate to the technical field of communication and are invented for enhancing the accuracy of evaluating the quality of an Internet protocol television (IPTV) business. The method comprises the following steps of: obtaining a channel video stream and also obtaining the decoding characteristic parameter of a decoder, wherein the decoding characteristic parameter at least comprises decoding buffer capacity; and obtaining the loss rate of frame information according to the decoding characteristic parameter, also obtaining the MOS-V parameter of the mean opinion score of the video according to the channel video stream, and obtaining the MOS-V value of the channel video stream according to the loss rate of the frame information and the MOS-V parameter. The embodiment of the invention is mainly used in a technology for evaluating the quality of the video.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a video quality evaluation method and device. Background technique [0002] With the development of communication technologies, an IPTV (Internet Protocol Television, Internet Protocol Television) service, as a kind of telecommunication service, has entered a stage of large-scale commercial use. At present, the quality of IPTV services is generally evaluated by calculating the MOS-V value (Mean Opinion Score-Vedio, video average opinion score), wherein, when calculating the MOS-V value, the parameters considered generally include network and service KPI (Key Performance Indication, key business indicators) parameters, such as frame size, frame information loss rate, frame type, content richness, motion, scene switching and other parameters. [0003] However, in the process of implementing the present invention, the inventors found that the existing method for calc...
