T/INFOCA 1-2017 The requirements and scenarios for video experience evaluation

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 take the bearing network factors as the main consideration factors. It mainly targets the influencing factors of the business layer and content layer. The first batch of projects is expected to have the following architecture: - Requirements and scenarios for 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 Technology Expert Group for Audiovisual Services This standard plans to include: video service user experience evaluation technology, methods for classifying video service types, various video service application scenarios and user experience evaluation requirements, and extended application scenarios of user experience evaluation technology.
