摘　　要：HEVC协议是继H.264标准之后最新并且具有很大影响力的国际视频编码标准,在数字广播电视等领域有十分广阔的应用前景,其出色的压缩效率将给带宽要求严格的乘客信息系统带来很大突破。本文首先介绍HEVC在H.264基础上发展技术优势,然后对HEVC高清视频流在乘客信息系统中无线网络传输中应用提出可行的解决方案。As the successor to H.264, the HEVC was the latest international video compression standard and had a great effect, was with a very broad application prospects in the field of digital television and etc. Its excellent compression efficiency would bring great breakthrough to the Passenger Information System which was strictly in network bandwidth demand. This paper firstly introduced the advantages of the HEVC based on H.264, and then put forward feasible solutions for the application of HEVC HD video streaming in the Passenger Infonnation System with wireless network transmission.
