Embodiment Construction

[0049] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0050] as attached figure 1 As shown, the present invention is a QoE-driven multi-channel HAS code rate adaptive scheduling method, through three factors of video content type, code rate, and freezing, the QoE model of multi-channel HAS is established; secondly, the server calculates each channel The message parameter value of the channel and pass the message parameter value of the channel to each user, where the message parameter is the average bit rate AverageQuality of the users in the channel i , average bit rate level AverageLevel i , the intensity of resource competition U i ;Finally, according to the received message parameter value of the channel and the QoE model of the multi-channel HAS, the client formulates a QoE-driven multi-channel HAS code rate adaptive algorithm, and calculates the code rate level of the user's next video slice...

Abstract

The invention relates to a QoE (Quality of Experience, quality of experience, user experience)-driven adaptive scheduling method of multichannel HAS (HTTP Adaptive Streaming, HTTP adaptive streaming media) code rate. The method comprises the following steps: establishing a QoE model of multichannel HAS by three factors of video content type, code rate and Kartun; calculating a message parameter value of each channel by a server, comprising an average code rate, an average code rate level, a resource competition intense degree in the channel, and transmitting the message parameter value of each channel to each user; and formulating a QoE-driven adaptive multichannel HAS code rate algorithm according to the received message parameter values of the channels and the QoE model of multichannel HAS, and calculating the code rate level of a next video slicing request of each user.

Description

technical field [0001] The invention belongs to the technical field of multimedia on-demand, and relates to video-on-demand, video service providers, cloud services, cloud bandwidth leasing to provide multi-channel services, and the fairness of multi-user resource competition, in particular to a QoE-driven multi-channel HAS code rate automatic Adapt to the scheduling method. Background technique [0002] With the rapid development of WiFi, 3G, 4G and even LTE wireless communication technologies and various mobile smart terminals, users can access multimedia video resources anytime and anywhere on various devices. In order to cope with heterogeneous terminals, HTTP adaptive streaming media technology came into being pregnancy. HTTP Adaptive Streaming Technology (HAS, HTTP Adaptive Streaming) has become the current mainstream streaming technology and has received more and more attention. HAS technology divides the video into multiple slices, and stores multiple versions with...
