doi:10.7523/j.issn.2095-6134.2014.01.017

Abstract

Abstract:

In this paper, an application-layer QoS(quality of service) control method for real-time video transmission based on 3G network is proposed. This method calculates packet loss rate using a linear prediction algorithm, and it introduces a self-designed SILD(strict increase loose decrease) congestion control algorithm to adjust the transmission bit rate of video streams. Experimental results show that the performance parameters, such as transmission delay and jitter, meet the industrial standard requirements and that the utilization of network bandwidth is improved. Therefore, the proposed QoS control method is suitable for real-time video transmission over 3G network and has good practicality and feasibility.

Key words: 3G, video transmission, QoS
