The TV programs we watch usually use analog signals to transmit sound images
Analog television
Digital television from the collection of programs, recording broadcast, transmission to receive, all use digital coding technology. With digital television, viewers can not only see DVD-like clear images, enjoy the sound effects of home theater, TV channels from dozens to hundreds of sets, listen to digital radio, but also can choose a variety of professional, personalized multimedia services.
The digital TVS sold on the market, in the strict sense, are not digital TVS, but digital TV signal displays (HDTV READY). Because such a digital TV can not directly watch digital TV programs, but also need to connect a set-top box, receive and convert the signal format. It doesn't matter how high the resolution of your digital TV is without a set-top box.
However, the digital TV all-in-one does not need a set-top box, so the digital TV all-in-one is considered to be "digital TV in the true sense", representing the future direction of digital TV development, and watching digital TV through the set-top box is a transitional measure, is the national machine card separation policy, or the temporary measure before the national digital TV standard is not introduced. Ms. Bai Weimin, secretary general of China Video Industry Association, also believes that the future development direction of digital TV is
Digital TV in one
Set-top boxes are transitional products.
Digital TV all-in-one is actually a digital-to-analog all-in-one, that is, compatible with both digital and analog signals. The digital TV signal can be watched directly when the card is inserted, and all analog TV signals can be watched without the card, which is no different from the TV we use today. This is the basic reality that it will take some time to fully consider the popularity of digital TV in China.
