基于H264AVC的视频水印技术论文

-0-基于H.264/AVC的视频水印技术作者于强指导教师刘争艳摘要当前，多媒体通信随着网络技术的进步得到了空前的发展，并且已经成为信息产业中发展最为迅速的部分。作为多媒体服务重要组成部分的数字音视频技术已经得到了极大的发展和广泛的应用。数字音视频产业是我国信息产业的三大组成部分之一，有望在“十一五”末期成长为年产值超过万亿元的国民经济第一大产业。但是目前在Internet上传输视频有许多困难，主要原因就是由于目前宽带接入的方式较多的还是由传统的电话网改造而成的，接入个人终端的实际带宽还是很低的。为了在Internet上有效的、高质量的传输视频流，需要多种技术的支持，其中数字视频的压缩编码技术是Internet视频传输中的关键技术之一。H.264/AVC是由ISO/IEC与ITU-T组成的联合视频组(JVT)制定的新一代视频压缩编码标准，于2003年5月完成制订。相对于先前的标准，H.264/AVC无论在压缩效率、还是在网络适应性方面都有明显的提高，因此，业界普遍预测其将在未来的视频应用中替代现有的视频压缩标准。关键词：H．264／AVCInternet数字音视频技术信息产业压缩编码技术多媒体通信-1-abstrctCurrently,multimediacommunicationsalongwiththeprogressofnetworktechnologyhasbeenanunprecedenteddevelopment,andtheinformationindustryhasbecomethefastestgrowingpart.Asanimportantcomponentofmultimediaservices,digitalaudioandvideotechnologyhasbeenagreatdevelopmentandwideapplication.DigitalaudioandvideoindustryisChina'sInformationIndustry,oneofthethreemajorcomponents,isexpectedtoEleventhFive-Yeargrowintothelatetrillionyuanannualoutputexceedsthelargestindustryinthenationaleconomy.ButatpresenttheInternettotransmitvideotherearemanydifficulties,largelyduetothewaythecurrentbroadbandaccessisstillmoretransformationfromthetraditionaltelephonenetworkmadeof,accesstoindividualterminals,theactualbandwidthisstilllow.InordertoInternet,effective,high-qualitytransmissionofvideostreamsneedtosupportmultipletechnologies,includingdigitalvideocompressioncodingtechnologyistheInternetvideotransmissionofthekeytechnologies.H.264/AVCbytheISO/IECandITU-TformJointVideoTeam(JVT)todevelopanewgenerationofvideocompressioncodingstandard,wasfinalizedinMay2003.Relativetothepreviousstandards,H.264/AVCintermsofcompressionefficiencyandadaptabilityinthenetwork,ortherearemarkedimprovements,therefore,theindustrygenerallypredictthatitwillinfuturevideoapplicationstoreplaceexistingvideocompressionKeywords:H．264／AVCInternetDigitalaudiovideocompressiontechnologyinformationtechnologymultimediacommunication-2-目录1H.264/AVC的介绍.......................................................................................................51.1概述.....................................................................................................................51.2H.264/AVC的标准.............................................................................................51.3H.264/AVC的技术细节.....................................................................................51.4H.264/AVC的专利许可.....................................................................................71.5H.264/AVC的应用...............................................................................................71.5.(1)光碟储存....................................................................................................71.5.(2)欧洲与北美洲地区....................................................................................71.5.(3)亚洲地区....................................................................................................81.5.(4)卫星数码电视............................................................................................81.5.(5)通讯与多媒体............................................................................................82视频水印技术综述.........................................................................................................92.1概述.....................................................................................................................92.2视频水印技术的主要特征................................................................................102.3非压缩域的视频水印........................................................................................102.4编码域的视频水印.............................................................................................112.5压缩域的视频水印.............................................................................................112.6视频水印的方案.................................................................................................112.7视频水印的分类................................................................................................122.8视频水印的发展趋势........................................................................................123AfterEffects的介绍.....................................................................................................133.1软件简介...........................................................................................................133.2主要功能...........................................................................................................133.3基本参数...........................................................................................................133.4模板设置...........................................................................................................144实例制作......................................................................................................................154.1前期素材制作...................................................................................................15-3-4.1．1所需软件.................................................................................................154.1．
