T/INFOCA 2-2017 Video service user experience evaluation system and architecture

Scope

Main technical content: Compared with voice data services, video services consume more bandwidth resources, have higher real-time requirements, and are very sensitive to network characteristics such as data loss, latency, and jitter. The key factors affecting users' video experience mainly include the quality of the video source, the quality of the audio source, and the user's service interaction experience and viewing experience; in addition, human-computer interface and ease of use also have a certain impact. This standard involves but does not introduce factors of the bearer network as the main consideration. It mainly focuses on the influencing factors of the business layer and the content layer. The first batch of projects is expected to have the following architecture: - Requirements and scenarios of video service experience evaluation - System architecture for video service user experience evaluation - Video service user evaluation algorithms and parameters - Live streaming - Video service user evaluation algorithms and parameters - On-demand playback - Charter of the Technical Expert Group for Subjective Evaluation of Audiovisual Services This standard plans to include: On-demand video service user experience indicator system, On-demand video service user experience indicator composition, Video service user experience evaluation algorithms (including overall model, main modules of the model)
