摘要

本文基于硅芯片调谐器XC3028和视频处理器SAA7111设计了一种具有无线电视接收功能的LCoS头盔显示系统。该系统由无线电视接收电路、视频处理电路、音频处理电路和LCoS显示屏组成，在有无外置视频输入源的情况下均可工作。首先，对系统的总体方案做了全面描述。然后，从硬件角度详细介绍了系统各部分功能和设计方案。最后，运用模块化设计方法完成系统软件设计。实验结果表明，整个系统设计合理、工作稳定、显示效果清晰。电路尺寸只有46 mm54 mm，总功耗仅为1.9 W。该系统具备体积小，功耗低、结构简单等特点，在移动视频终端领域将有更广泛的使用价值和推广前景。

Abstract

A LCoS head-mounted display system with terrestrial TV receive function based on silicon tuner XC3028 and video processor SAA7111 is designed in the paper. The system consists of terrestrial TV receiving circuit

video processing circuits

audio processing circuits and LCoS display. It can work properly with or without external video source. The overall design scheme of system is introduced in the first place. Then the functions and design schemes of various parts are presented from a hardware perspective. Finally

a modular design method is adopted to complete system software design. Experimental result shows that this system has features of rational design

stable operation and clear display effect. The circuit dimension is only 46 mm54 mm and the power dissipation is 1.9 W. The system meets the requirements of compact size

low power dissipation

simple structure and has a promising market prospect in the field of mobile video terminals.
