Analog TV vs Digital TV vs IPTV
Hi, Mianhong will introduce and compare different types of TVs: analog TV, digital TV, and IPTV.
Again, Mianhong is a TV OEM factory with 12+ years of experience. Mianhong produces analog, digital, and IPTV with various sizes and resolutions. Mianhong aims to provide the best TV products so customers can enjoy colorful TV channels.
ATV: Analog TV refers to TV that uses analog signal encoding, decoding and modulation transmission methods. The three popular color television broadcasting systems in the world, NTSC, PAL, and SCEAM, are all developed on the basis of the established black and white television broadcasting system. Technically, they are compatible with color television systems and their corresponding black and white television system compatibility requirements.Analog TV is the most traditional TV after the black/white TV. An analog TV receives an analog signal and parses the analog signal into a readable visual signal by human eyes. Remember, television is a complicated system that reproduces/restores live or recorded images and audio signals to a remote place. From the front end, which produces an analog TV, some machines make analog signals to let the TV(back) parse the signal. NTSC, PAL, and SECAM are the primary three analog systems. All of them are unique regarding scanned lines, frame per second, and voltage to activate RGB nodes. For example, the NTSC system requires 525 scanned lines and 60 frames per second.
DTV: Digital TV system refers to a TV system that uses digital technology in all aspects from studio program production to transmission, storage, transmission, reception, and display. Digital TV is a large system. A complete digital TV system includes the generation, processing, transmission, reception and reproduction of digital TV signals.Digital TV aims to solve the disadvantages of analog TV. Up to 2023, many countries get rid of using analog TV. The Analog signal is not stable. In analog communication, to improve the signal-to-noise ratio, it is necessary to amplify the attenuated transmission signal on time during the signal transmission process, and the noise inevitably added during the transmission process is also amplified simultaneously. As the transmission distance increases, the accumulation of noise increases, leading to a severe transmission quality. With the usage of digital signals, this problem will be solved. In addition, the digital signal is unified, and customers do not need to worry about regulating NTSC, PAL, and SCEAM. However, some TVs can receive and read analog and digital signals simultaneously.
IPTV: IPTV stands for Internet Protocol television. It uses Internet, multimedia, communication and other technologies to provide a variety of interactive services such as digital TV to users. IPTV is the trending type of TV because it only requires a network, whether RJ45 port or a WIFI network. With an IPTV, customers can only enjoy TV channels with a network instead of installing a TV satellite dish at home. On the other hand, IPTV is not restricted by the "TV machine." It can be a computer that uses the Internet to watch TV channels online or a combination of "TV BOX + TV."
Why IPTV Are Different?
Compared with traditional TV, IPTV has the following differences:
– IPTV does not need to be transmitted through cables or antennas. It only needs to use devices with the ability to access the Internet.
– IPTV provides more customized content, while on traditional TV, you can only watch local channels;
– Compared with digital TV, IPTV is more flexible because it can be watched on demand anytime, and pausing is OK. The traditional TV is relatively passive because the users need to arrange the time for TV channels. It is a time loss for the audience and a waste of resources for the broadcast service provider.
– IPTV is limited to network bandwidth. The content displayed will also be wrong if there is a lousy bandwidth.
If you are a distributor, it is crucial to understand the market and TV system in your country. Some countries have banned digital TV because the digital signal is uncontrollable, and people can illegally watch unwanted channels. On the other hand, some digital TVs are compatible with analog because the mainboard has included the analog Low Noise Block Down Converter(LNB, aka tuner).
