电视棒中Android图形显示的改进算法

The Improved Algorithms Based on Android Display System in HDMI Stick

首先简要介绍了智能电视、电视棒以及Android图形显示系统的原理。然后分析了Android图形显示系统应用到电视棒时会产生的问题,一是电视的过扫描问题,过扫描会引起图像失真,尤其是图像边缘;二是多分辨率问题,电视具有多种分辨率,但Android图形显示系统只支持固定的分辨率。最后提出了处理过扫描问题及多分辨率问题的具体算法,并进行了相关实验。实验证明了提出的改进算法确实解决了Android图形显示系统应用到电视棒时的过扫描及多分辨率的问题。

Smart TV, HDMI Stick and Android Graphic System are first introduced . Then the problems when the Android graphic system applied to the HDMI Stick are analyzed. One problem is overscanning which will cause image distortion, especially the image edge. The other is multiple resolution. Television has a variety of resolution, but Android graphics display system only supports the fixed resolution. Finally it puts forward the concrete algorithms to manage overscanning and multiple resolution problems. Experiments show that the proposed algorithms can indeed solve the problems of overscanning and multiple resolution when Android graphics display system applied to HDMI Stick.
