Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0045] For game live broadcast service providers, in order to make full use of cloud resources, optimize user service strategies, and further reduce operating costs on the basis of satisfying user experience quality, this invention proposes an adaptive streaming transcoding resource allocation in the game live broadcast platform method. Using adaptive streaming technology, this method fully considers factors such as user needs and resource constraints, and reasonably selects an online video transcoding version to provide users with a good viewing experience and reduce operating costs. The present invention designs an optimization method for online transcoding resource allocation based on adaptive streaming technology by establishing a user QoE model and a platform overhead model, based on a cloud com...

Abstract

The invention discloses an adaptive video stream transcoding method applied to a game live broadcast platform. The method comprises the following steps: cutting a video live broadcast platform operation period into a plurality of time periods; in each time period, updating state information in the platform; according to current state information, marking a decision about a transcoding resource distribution plan, wherein constraint conditions for the plan within the operation period are as follows: minimizing service cost of a game live broadcast service provider and maximizing a QoE sum of users at the same time; and applying the transcoding resource distribution plan to a current live broadcast stream. According to the invention, the definition of a user QoE model is constructed, and a unified QoE model is provided for different game types through introduction of a game type factor, which represents a foundation stone of a user resource distribution algorithm.

Description

technical field [0001] The invention relates to the field of game live broadcast and cloud computing resource management, in particular to an adaptive streaming resource allocation method applied to game live broadcast. Background technique [0002] Video games originated in the mid-twentieth century, and the earliest video games were the cathode ray tube entertainment device (CathodeRayTubeAmusementDevice) invented by ThomasT.GoldsmithJr. and EstleRayMann in 1947. Today, video games have become one of the main forms of entertainment for people. With the development of network technology and streaming media technology, people are no longer satisfied with playing games by themselves, but are eager to share their game experience with others, so game live broadcasting came into being. Service providers provide game live broadcast platforms (such as Douyu) so that players can broadcast live games in real time, and viewers can watch and communicate with each other online through...
