T/INFOCA 3-2017 Video service user evaluation algorithm and parameters - Live streaming (English translation)

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 the factors of the bearer network as the main consideration factors. It mainly targets the influencing factors of the business layer and the content layer. The first batch of project plans are expected to be structured as follows: - 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 - Charter of the Technical Expert Group for Subjective Evaluation of Audio and Video Services. This standard plans to include: Indicator system for user experience of live video services, composition of user experience indicators for live video services, and user experience evaluation algorithms for video services (including the overall model and the main modules of the model).
