METHOD, APPARATUS, AND SYSTEM FOR ADJUSTING MULTIMEDIA ENCODING RATE
First Claim
1. A method for adjusting a multimedia encoding rate, comprising:
- obtaining an available network bandwidth corresponding to a transmission path of a multimedia service;
obtaining expected quality of experience (QoE) of the multimedia service and a current multimedia encoding rate; and
obtaining an expected multimedia encoding rate by using the available network bandwidth, the expected QoE of the multimedia service, and the current multimedia encoding rate as input parameters and according to a preset multimedia resource decision policy, wherein the expected multimedia encoding rate is used as a reference for adjusting the current multimedia encoding rate.

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 available network 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 disclosure, 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.
