摘　　要：数字电视机顶盒作为一类嵌入式设备,相比于个人计算机,它具有处理能力偏低、资源受限等特点。常用的PC端浏览器支持全面的web特性,直接移植至机顶盒会造成内存占用过大、运行效率低的问题。考虑到机顶盒浏览器面向的主要是视频业务,基于Chromium浏览器提出并实现了一种面向视频业务的嵌入式浏览器加速方法,从重构浏览器架构和简化内核标准支持两个方面对Chro mium浏览器进行优化,以更好地适配数字电视机顶盒的视频业务。实验结果表明,基于该方法的嵌入式浏览器比直接移植到机顶盒端的Chromium浏览器在同等网络情况下,常用视频业务的启动加载主页耗时、遥控交互单次耗时和视频加载耗时3个方面分别平均减少了40%、70%和50%。As a kind of embedded device,digital TV set top box has the characteristics of low processing power and limited resources compared with personal computers.Commonly used PC side browsers support comprehensive web features,and direct migration to a set top box can cause excessive memory usage and low operational efficiency.Considering that the set top box browser is mainly for video services,this paper proposes and implements an embedded browser acceleration method for video services based on Chromium browser.The Chromium browser is optimized from two aspects:browser architecture and kernel standard support to fit the video service of digital TV set top boxes better.The experimental results show that the embedded browser based on this method is 20%faster than the Chromium browser directly ported to the set top box.
