A lot of us have seen that random strip of numbers appearing on our TV screens while watching our favourite shows. But have you ever wondered what that random strip having unique numbers or codes flashing on your TV screen mean?
These numbers are basically used by the content providers to avoid and detect piracy.
The numbers that you see on the corner of your TV screens are unique for every region and are generated using a special algorithm. Once generated, these unique numbers are then inserted into the video streaming at random points and can’t be taken down using video processing algorithms.
And by using these numbers, content providers can track down the people responsible for capturing content off-air and replaying it over the internet or on some other means without permission.
Now, you know the reason!
