数字电视机顶盒客户端图形界面软件的设计与实现

The Design and Implementation of USIF Software for Digital Television Receiver

介绍图形界面软件的设计过程及其实现方法。在结构模块的设计中,引入了面向对象的概念,通过定义软件元素的数据结构和合理调用相应的成员函数来实现客户端图形界面,在实际使用过程中良好地显示了图形和文字,并能实现自动搜台、视频点播等多种功能。

This paper studies the design and implementation of Client Graphical Interfaces（CGI） software. In designing the module structure, the concept of object-oriented is introduced and the implementation of CGI is achieved by defining the data structure of the software elements and appropriately invoking corresponding mem- ber function. In practical application, this interface primly displays images, scripts and realizes such multiple functions as automatic channel-searching and video-on-demand.
