松下NV—G20录像机自身具有N4.43/LP录放功能,只是有待于使用者的开发。笔者现介绍该机增加N4.43/LP功能的具体方法: 一、增加N4.43/LP录放功能:见图1所示。 NV—G20录像机的系统控制集成电路是采用微处理器IC_(6001)(MN15362VJR),该处理器潜有PAL/NTSC双制式功能,由IC_(6001)第⑦脚所输入的直流电平所控制。当⑦脚为高电平时,该机工作于PAL状态,
Panasonic NV-G20 VTR itself has N4.43 / LP recording and playback capabilities, but to be user-developed. I now introduce the aircraft to increase N4.43 / LP specific ways: First, to increase N4.43 / LP recording and playback functions: shown in Figure 1. The system control integrated circuit of NV-G20 video recorder adopts the microprocessor IC_ (6001) (MN15362VJR). The processor has the function of PAL / NTSC dual-function and is controlled by the DC level input by pin ⑦ of IC_ (6001). When ⑦ pin is high, the aircraft work in the PAL state,
