Real-Time Quality Monitoring for Networked H.264/AVC Video Streaming
Abstract
In this paper a packet-layer model for video quality assessment is proposed to monitor the service quality of networked H.264/AVC video streaming in real-time. Using the information extracted from packet header, the frame type is first predicted, based on which the structure of the group of picture (GOP) is estimated since quality degradation caused by packet loss is significantly affected by the loss position. Then the number of impaired frames due to packet loss is calculated as an input of the proposed model. Moreover, since the video quality significantly relies on the motion characteristic of the video content, an algorithm to measure the temporal complexity is designed and incorporated into the proposed model. Eventually, the quality of each GOP can be calculated and the correspondingly video quality is derived using the temporal pooling strategy. Experimental results show that the proposed model remarkably outperforms the model recommended as ITU-T G.1070.
