Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] Such as figure 1 Shown, described IPTV video streaming service user quality of experience subjective and objective comprehensive evaluation method, comprises the following steps:

[0054] Step 1: collect the parameters generated by the IPTV user when watching the video, the parameters include QoS parameters and status parameters;

[0055] Wherein, the collected QoS parameters specifically include:

[0056] ① Delay (Td): the time from the user request to the final creation of the user request;

[0057] ② Jitter (Jitter): The time interval between two adjacent data packets received by the user;

[0058] ③ Media packet loss rate (Pmlr): Indicates the transmission packet loss rate of the tested video stream;

[0059] ④ Packet loss rate (Pplr): the ratio of the number of lost data packets to the sent data group;

[0060] ⑤ Switch...

Abstract

The invention discloses a subjective and objective comprehensive evaluation method for IPTV video stream service user experience quality, which includes the following steps: Step 1: collecting QoS parameters and state parameters generated by IPTV users when watching videos; Step 2: using data mining technology to collect The QoS parameters are processed to determine the key QoS parameters in the IPTV video service; and according to the status parameters, obtain the viewing rate and the viewing mode, which represent the user's preference and influence the user's acceptance; step 3: process the The key QoS parameters and personalized parameters are brought into the user experience quality evaluation model based on statistical methods to obtain the user experience quality score. The evaluation model including personalized parameters proposed by the invention can make the obtained evaluation result closer to real user experience, improve the accuracy of QoE evaluation of IPTV video stream service, and help operators to better improve services.

Description

technical field [0001] The invention relates to the field of user experience evaluation of video streaming services, in particular to a subjective and objective comprehensive evaluation method for user experience quality of IPTV video streaming services. Background technique [0002] With the continuous development and application of Internet technology, people have higher and higher requirements for multimedia service quality. At the same time, various multimedia services (such as Interactive Internet Television (IPTV), Internet Phone (VolP), etc.) are constantly emerging. IPTV integrates various technologies such as the Internet, multimedia, and communication, and is highly sensitive to network damage such as packet loss, network jitter, and transmission delay. Therefore, mobile IPTV service operators must establish a complete video service quality (Quality of Service, QoS) and terminal user experience quality (Quality of Experience, QoE) evaluation system. In particular...
