目前,采用国际最新技术大规模数字集成电路,融多画面、画中画、图像菜单诸多功能为—体的双调谐器、高清晰度画中画彩电正大步进入消费市场,成为彩电市场的一枝红杏,倍受宠爱。据了解,起初的画中画技术最多只达到一个大画面加上一个小画面。功能大体分为两类:一类是小画面只能接收 AV 端子输入信号,即所谓的视频画中画,其主画面可接收电视信号,小画面可接收来自录像机、VCD 机等一些视频设备的信号,这种双画面对一些已
At present, using the latest international technology large-scale digital integrated circuits, financial multi-picture, picture in picture, picture menu many functions as a body tuner, high-definition picture-in-picture TV is a big step into the consumer market, a TV market Apricot, much loved. It is understood that the first picture-in-picture technology at most only reached a large screen with a small screen. The functions are generally divided into two categories: one is the small screen can only receive the AV terminal input signal, the so-called video picture in picture, the main screen to receive TV signals, small screen can receive video recorders, VCD machines and some video equipment Signal, this kind of double-screen to some already
