Abstract

A method, an apparatus, and a system for adjusting a multimedia encoding rate are disclosed. The method includes: obtaining an expected multimedia encoding rate by using the network available bandwidth corresponding to the transmission path of a multimedia service, the expected QoE of the multimedia service, and the current multimedia encoding rate as input parameters and according to a preset multimedia resource policy decision, where the expected multimedia encoding rate is used as a reference for adjusting the current multimedia encoding rate. With the present invention, under the current network performance, an optimal point for balancing the effects of the media encoding rate and the network performance on the QoE is found by adjusting the multimedia encoding rate, thus achieving optimal QoE. In this way, the adjustment process is simple and fast and the success rate is high, thus improving the QoE.

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, ...
