Watching television is indeed quite engaging and has become one of the most favorite pastimes of the present generation. But have you ever wondered what are those random numbers which appear on your TV screen for some time and then disappear?
TV channels use these numbers as a measure to check piracy!
Here’s how it works:
The number that you see on the screen of your television is created using some algorithm for every region. This number is intermingled with the video for some place so that nobody would be able to remove that number from the screen, using any technique or algorithm.
Now if someone tries to record that video on which number is seen, then with the help of this number, company will be able to track the location of recording and hopefully it can also catch the people involved in the illegal act.
Quite interesting, isn’t it?
