HDTV机顶盒中用户界面的设计与实现

Design and implementation of user interface in HDTV set-top-box

以ST高清晰度电视机顶盒方案为例,首先介绍STi7000提供的OSD单元的特点和原理,并在此基础上设计并实现了一个OSD硬件抽象层(HALOSD),然后利用OSD硬件抽象层实现了系统的用户界面。

Firstly this paper using ST HDTV Set-Top-Box scheme introduces the features and the principle of STi7000's OSD unit,based on above theory an OSD Hardware Abstract Layer(HALOSD)was designed and realized,finally the user interface of this system base on HALOSD was implemented.
