Abstract: This paper presents a Chinese input method based on any common remote control pad. This input method consumes only a few memory resources. It uses ten number keys and five keys for control to implement the Chinese input method. It supports Chinese, English, interpunction and special symbol input. The input method is imbedded in digital TV set top box and shows the input result on the screen of TV set. This input method is transplantable, and can be applied to many digital TV interactive services. It presents the design and implementation of the input method, including framework, function description, data storage structure, and the process flow.

Key words: embedded system, DTV set top box, remote control pad, Chinese input method

摘要： 介绍了一种占用较少资源在普通电视机遥控器上实现的中文输入法，该输入法采用遥控器上的数字键0~9加上5个控制键实现中文的拼音汉字输入、英文字母输入、标点和特殊符号的输入。以数字电视机顶盒为平台，以普通电视机屏幕为显示终端，具有良好的可移植性，可应用于双向有线网的各种交互业务中。描述了该遥控器输入法设计的功能、总体框架、存储结构、处理流程等。
