Method, device and system for adjusting multimedia encoding rate

Abstract

The embodiment of the invention mainly aims to provide a method, a device and a system for adjusting a multimedia encoding rate. The method comprises the following steps: using a network available bandwidth of a transmission path of a multimedia service, an expected value of the quality of experience QoE of the multimedia service and a current multimedia encoding rate as input parameters; and acquiring an expected multimedia encoding rate according to a preset multimedia resource decision policy, wherein the preset multimedia encoding rate is used as a basis for adjusting the current multimedia encoding rate. The method solves the problem of realizing an optimal balance point of the actions of the multimedia encoding rate and network performance on the quality of experience QoE and meeting the quality of experience QoE of a user by adjusting the multimedia encoding rate under the current network performance, realizes the optimal balance point of the actions of the multimedia encoding rate and network performance on the quality of experience QoE, makes the adjustment process simple and quick with high success rate and improves the level of the experience of the user.

Description

technical field [0001] The invention relates to network technology in the communication field, and specifically refers to a method, device and system for adjusting multimedia coding rate. Background technique [0002] With the development of multimedia communication technology, various multimedia services emerge in an endless stream, so the quality of multimedia services plays a very important role in the fields of multimedia processing and multimedia communication. [0003] In multimedia services, such as IPTV and wireless services, because the traditional network layer QoS quality parameters cannot intuitively reflect the user's quality of experience, the QoE value of experience (Quality of Experience) is currently used to measure the user's experience of video quality. [0004] The prior art proposes that in the IP multimedia service, the QoE experience quality of the user is improved according to the QoE parameter value fed back by the user to the media server, that is, ...
