一、引言目前,销售最广的家用盒式磁带录象机(VCR)是台式VCR,其中配备了电视(TV)高频头,这种高频头的主要功能是记录电视节目。为了提高VCR的市场竞争能力,我们感到发展一种先进的便携式VCR是极为重要的,这种VCR既可在家庭又可在室外连同摄象机一道进行录象。发展这种便携式VCR时主要考虑之点是: ①由于尺寸较小,重量较轻,其便携性更佳。②由于功耗较低,电池使用寿命更长。③兼有高级功能,操作简便。围绕着这些目标,我们发展了一种比普通VCR更小、更轻和功耗更低的新型便携式VCR。开始研制
I. INTRODUCTION At present, the most widely sold home videocassette recorder (VCR) is a desktop VCR equipped with a TV tuner. The main function of this tuner is to record television programs. In order to enhance the market competitiveness of VCRs, we feel it is extremely important to develop an advanced portable VCR that can record both home and outdoors together with video cameras. The main consideration when developing this portable VCR is: 1) its portability is better due to its smaller size and lighter weight. ② due to lower power consumption, longer battery life. ③ both advanced features, easy to operate. Around these goals, we have developed a new portable VCR that is smaller, lighter and consumes less power than regular VCRs. Start development
