介绍YGV629的基本结构和特性论述实现图形视频叠加的基本原理,给出基于YGV629的车载DVD音影系统图形化用户界面的设计方案,并讨论关键元器件的选取及使用注意事项。该设计方案实现的车载音影系统操作界面友好,灵活性强。只需修改相应的图形库即可应用于需要视频图形叠加的其他领域。
- Abstract:
- The basic configuration and feature of YGV629 are introduced in this paper.The basic principle of graphic video blending are analysed.This paper presents a solution of graphic display interface based on YGV629for vehicle DVD,and discusses the key components selection.This solution makes manipulation of video-audio system more friendly and is easy to use.Because of flexibility of this solution,only modifying pattern memory,it can be used to other fileds of video blending.
