Multimedia quality monitoring method, and device

摘要

Embodiments of the present invention provide a multimedia quality monitoring method, and a device. The method includes: determining reference quality of multimedia according to reference video quality and reference audio quality of the multimedia; acquiring multimedia distortion quality after at least one of video distortion and audio distortion of the multimedia occurs; and determining quality of the multimedia according to the reference quality of the multimedia and the multimedia distortion quality. Therefore, accuracy of a multimedia quality monitoring result is improved.

主权项

1. A multimedia quality monitoring method, comprising:
determining, by a multimedia quality monitoring apparatus, reference quality of multimedia according to reference video quality and reference audio quality of the multimedia; acquiring, by the multimedia quality monitoring apparatus, multimedia distortion quality after at least one of video distortion and audio distortion of the multimedia occurs; and determining, by the multimedia quality monitoring apparatus, quality of the multimedia according to the reference quality of the multimedia and the multimedia distortion quality; wherein the multimedia distortion quality comprises: multimedia distortion quality due to at least one of packet loss and rebuffering; and wherein acquiring the multimedia distortion quality after at least one of video distortion and audio distortion of the multimedia occurs comprises: determining, at least one of the following: (a) according to the reference video quality and a video packet loss rate, video quality due to packet loss after a packet in a video of the multimedia is lost, and (b) according to the reference audio quality and an audio packet loss rate, audio quality due to packet loss after a packet in an audio of the multimedia is lost; acquiring the multimedia distortion quality due to at least one of the following: (i) packet loss according to the video quality; and (ii) rebuffing parameter, during a transmission process, of the multimedia; wherein acquiring the multimedia distortion quality due to at least one of the video quality due to packet loss and the audio quality due to packet loss comprises: determining at least one of video distortion quality due to packet loss and audio packet loss distortion quality due to packet loss, wherein the video distortion quality due to packet loss is determined according to the video quality due to packet loss and the reference video quality, and the audio packet loss distortion quality due to packet loss is determined according to the audio quality due to packet loss and the reference audio quality; determining at least one of a video packet loss distortion factor and an audio packet loss distortion factor, wherein the video packet loss distortion factor is determined according to the video distortion quality due to packet loss and the reference video quality, and the audio packet loss distortion factor is determined according to the audio packet loss distortion quality and the reference audio quality; determining a multimedia packet loss distortion factor according to at least one of the video packet loss distortion factor and the audio packet loss distortion factor; and determining the multimedia distortion quality due to packet loss according to the multimedia packet loss distortion factor and the reference quality of the multimedia.
