时下,新型彩电的功能越来越齐全。如何开发老式彩电的新功能,是一些用户的热门话题。例如:如何将老彩电改造成象新型彩电那样,不仅能接收电视信号,还能接收影碟机、录像机的音频、视频信号(简称AV)。下面将如何为乐华TC511-2PD/I(R)20英寸彩电加装音、视频接口作一介绍。 一、加装音频、视频装置 加装视频信号接口,主要解决两个问题,即视频信号输入机内的极性与幅度。乐华TC511-2PD/I(R)彩电公共通道集成块D5132输出的是正极性视频信号,经过
Nowadays, the new color TV functions more and more complete. How to develop new features of the old color TV, is a hot topic for some users. For example: how to transform the old color TV like a new color TV, not only to receive television signals, but also to receive DVD players, video recorders audio and video signals (referred to as AV). How to Leroy TC511-2PD / I (R) 20-inch color TV installation of audio and video interface for an introduction. First, the installation of audio and video equipment installation of video signal interface, mainly to solve two problems, that is, the video signal input polarity and amplitude within the machine. Lehua TC511-2PD / I (R) TV public channel manifold block D5132 output is a positive video signal, after
