HTTP媒体传输方式简述

A Brief Description of HTTP Media Transport

基于HTTP协议的媒体传输方式已经逐渐取代传统的媒体传输方式成为大多数视频分享网站和视频点播服务提供商的主流解决方案。随着视频分辨率在不断提高,对带宽的需求也在逐渐增加,然而当前用户仍然受网络波动、带宽不足等问题影响,在进行媒体播放时出现延迟、卡顿、缓冲等现象。基于上述背景,本文对基于HTTP的媒体传输方式、传输技术优化的关键因素等核心问题及现有研究进行了分析,同时总结分析了HTTP媒体传输领域未来的发展趋势。

The media transmission method based on HTTP protocol has gradually replaced the traditional media transmission method as the mainstream solution for most video sharing websites and video on demand service providers.As the video resolution continues to increase,the demand for bandwidth is gradually increasing.However,current users are still affected by network fluctuations and insufficient bandwidth,and delays,jams,and buffers occur during media playback.Based on the above background,this paper analyzes the core issues and existing research of HTTP-based media transmission methods and key factors of transmission technology optimization,and summarizes the future development trend of HTTP media transmission field.
