What is digital TV?

Digital television (Digital TV Receiver ) is the transmission of audio and video by discrete (digital) signals, in contrast to the analog signals used by analog TV.But what is the meaning of the car digital tv?Let’s compare it with the analog tv here:

1.Digital TV can receive signal even the car is moving at around 150KM/H,but the analog tv can not receive signal if the car is moving,just moving no matter how fast or slow it is,so the signal will go out and no siginal.That’s why so many Car DVD player built in the digital tv instead of the analog tv,if you want to watch tv when your car is running in road,so you have to install digital tv.That’s the reason that some of the factory don’t built in the analog tv inside the car dvd player,they thought it is no use,what is your opinion?So if you need tv in car,just select digital tv.

2.How to select digital tv?Which one can be work in my country?We had met some problem of the digital tv selection,so we list it again to make you clear:there are 3 kinds of digital tv standard in the world,they are DVB-T,ISDB-T and ATSC,do you know what you should select?Please follow:

DVB-T TV Receiver is an abbreviation for Digital Video Broadcasting — Terrestrial; it is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television that was first broadcast in the UK in 1997.[1] This system transmits compressed digital audio, video and other data in an MPEG transport stream, using coded orthogonal frequency-division multiplexing (COFDM or OFDM) modulation.so if you are from Europe,you can select this digital tv,but please note that there are some difference in MPEG-2 and MPEG-4,as our experience,most of the country use MPEG-2 for the standard signal,and MPEG-4 for HD signal,so please check and confirm if before order.If you still have questions about it,you can read the instruction here in Wiki:DVB-T.

ISDB-T TV Receiver will be easy to clear and select,it can be work in Japan, Brazil, Argentina only,so if you are outside these country,don’t select this standard.

ATSC TV Receiver is for North America including USA,Canada and Mexico.

Finally,we use DVB-T in some city in China,but most of us use CMMB in China,it is very different,thanks!
