Real-time analysis and recording of all video stream QoS and QoE quality metrics.
Product Overview
In response to the demand for parallel analysis of the output quality of a large number of IP video encodings, IneoQuest Expedus™ DVA assists users in efficiently detecting video quality. This product addresses two challenges in video detection: verifying the quality of video after processing; and serving as a reference point for end-to-end video quality monitoring to ensure good video transmission quality before distribution. By detecting parameters such as subjective video quality and audio-video quality loss, users can understand the changes in video encoding quality after processing (encoding, transcoding, ad insertion); by monitoring QoS metrics of the video, users can identify faults affecting QoE quality beyond video processing.
