T/INFOCA 4-2017 Video service user experience evaluation algorithm and parameters - On-demand streaming

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 video source quality, audio source quality, users' 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 consider the factors of the bearer network as the main consideration. It mainly focuses on the factors affecting the business layer and content layer. The first batch of project plans are expected to have the following structure: - 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 Subjective Evaluation Technical Expert Group for Audio and Video 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 and main modules of the model).
