Getting acquainted with Analog TV

Basically, the transmission of analog TV signals is almost similar to that of radio signals. The video signal is broadcast in AM format. While the audio is transmitted in FM. Unfortunately, this type of transmission is easily disrupted – for example, due to weather, geographical conditions, and much more.

Not only that, the amount of bandwidth assigned to analog TV channels makes the resolution and picture quality limited. Therefore, for those of you who still use this type of TV, of course, you will often find images that are damaged and cracked when it rains or while in mountainous areas.

What is Digital TV

Digital television, or often abbreviated as DTV, is television that receives the transmission of information in the form of data. Like data on a computer being transferred to a CD, DVD, or Blu-Ray disc.

Digital signal consists of 1 and 0. That is, between on or off. Unlike analog TV transmission, no signal is lost even if the transmission distance is further away. However, if the distance between the transmitter and the digital TV is too far, the signal will be difficult to catch.

Also, unlike analog TV, digital TV design is fairly comprehensive. Because it considers all the main factors of the signal. Starting from black and white, color, audio, and text.

Meanwhile, video can be transmitted as an interlaced signal (lines are scanned in an alternate plane) or progressive (lines are scanned in sequence.
