Abstract

The invention discloses a method for evaluating quality of streaming video based on video characteristics. The method is realized in a simulation environment of simulating network loss on MPEG-TS stream; network damage is simulated through man-made loss, simultaneously loss data is recorded, image characteristics of a damaged frame are analyzed, and impact of video damage to visual effect is observed by eye, thereby establishing a one-to-one correspondence. In practical application, a QoE evaluation value which is in accord with subjective feeling of a user can be acquired through sampling and analyzing a transmission media and analyzing the network damage. In the method an objective evaluation method and a subjective evaluation method are combined to ensure the evaluation value is closer to the real feeling of the user; evaluation is carried out through analyzing compressed domain data of video streaming in a streaming media service in real time, and feasibility of real-time analysis is higher.

Description

technical field

[0001] The invention relates to the technical field of quality of experience (QoE) of video users, in particular to a method for evaluating the quality of streaming video based on video features. Background technique

[0002] The rapid development of packet network technology represented by the Internet Protocol (IP) makes the packet network have the advantages of high bandwidth, convenient access, and low cost. The applications it provides are not simply limited to web browsing, email, and search engines. and other information tool applications, but extended to streaming media services such as IPTV. At the same time, streaming video services have high bandwidth, high real-time requirements, and are very sensitive to network impairments such as packet loss, disorder, transmission delay, and delay jitter. However, the traditional IP protocol as the core protocol of the packet network has only one service type, that is, the best effort service model, which doe...
