Problems solved by technology

The video data may be damaged in any link of the transmission process, resulting in a decrease in the user experience quality of the video
The above method can only evaluate the quality of video experience from the perspective of the end user, but cannot detect the quality of video experience in all links of the video service network. Therefore, it is difficult to effectively provide transmission guarantee and damage repair for video data

Embodiment 1

[0019] Embodiment 1 of the present invention provides a method for detecting video quality of experience. The method for detecting video quality of experience can be applied to a network system that provides video services, such as an IPTV system. see figure 1 The method for detecting the quality of video experience provided by Embodiment 1 of the present invention includes: step 101, the video source device acquires the importance degree information of the video encoding data block; step 102, the video source device encapsulates the video encoding data block into data transmission packet, and generate the importance information of the data transmission packet according to the importance information of the video encoding data block; step 103, the video source device synchronously transmits the data transmission packet and its importance information to the video network node, so that the video network node can use the importance information of the data transmission packet as o...

Embodiment 2

[0039] The video quality of experience detection method provided by Embodiment 2 of the present invention can also be applied to a network system that provides video services, more precisely, it can be applied to a video network node that detects video service user quality of experience in the network system side, for example, the access node on the video source side, the network node on the core network, the access node on the user side, or the video receiving device. In this embodiment, when the data transmission packet is damaged, the video network node can use the importance information of the data transmission packet as one of the bases to detect the quality of experience of the video service.

[0040] Specifically, see image 3 The video quality of experience detection method provided by Embodiment 2 of the present invention includes: first, the video network node receives a video data transmission packet and its corresponding importance information synchronously transmi...

Embodiment 3

[0052] Based on the methods for detecting video quality of experience provided by the first and second embodiments above, embodiment three of the present invention further provides a system for detecting video quality of experience. Specifically, the detection system of the video quality of experience may include:

[0053] The video source device is configured to encapsulate the video encoding data block into a data transmission packet, obtain the importance degree information of the video encoding data block and map it to the importance degree information of the corresponding data transmission packet, and convert the data transmission packet and The importance information is sent synchronously;

[0054] A video network node, configured to receive the data transmission packet and its corresponding importance information, and use the importance information of the data transmission packet as one of the bases to detect the video service when the data transmission packet is damage...

Abstract

The embodiment of the invention discloses a method for detecting the quality of experience of video, which comprises the following steps of: acquiring importance information about a video coding data block; packaging the video coding data block into a data transmission packet and generating the importance information about the data transmission packet according to the importance information aboutthe video coding data block; and synchronously transmitting the data transmission packet and the importance information thereof to a video network node, so that the video network node can detect the quality of experience of the video by taking the importance information about the data transmission packet as one of bases for the detection of the quality of experience of the video when the data transmission packet is damaged. Through the method for detecting the quality of experience of the video provided by the embodiment of the invention, the quality of user experience of video services can be relatively more accurately evaluated. The embodiment of the invention further discloses a system and equipment for detecting the quality of experience of the video.

Description

technical field [0001] The present invention mainly relates to the technical field of communication, and in particular, relates to a method, system and device for detecting video quality of experience (Quality of Experience, QoE). Background technique [0002] With the rapid popularization of network video services, the service quality of video services has become an important basis for video service guarantee. [0003] Generally speaking, the quality of video experience is to evaluate the service quality from the perspective of users. The current method used in the industry to evaluate the quality of video experience is that viewers score according to the viewing experience of sample videos, and then form a subjective evaluation based on the average score of the audience. The score value (Mean Opinion Score, MOS) is used to determine the quality of experience of the video service. However, since the above method is based on the viewing of sample videos by viewers, it is di...
