近年来国外家用盒式磁带录象机(以下简称家用录象机)发展很快,大有逐渐普及之势。在不断增长的市场需求推动下,家用录象机不仅产量增加很快,而且质量有所提高,功能不断完善。抛弃了几年前家用录象机以具备基本功能,保证基本图象质量的前提下主要追求低价格的目标,提出了辅助功
In recent years, foreign home video cassette recorders (hereinafter referred to as home video recorders) developed rapidly, the trend is gradually universal. Driven by the growing market demand, not only has the output of household video recorders increased rapidly, but the quality has been improved and the functions have been continuously improved. Abandoned a few years ago, household video recorders with basic functions to ensure the basic image quality under the premise of the main pursuit of low prices, the proposed auxiliary work
