No bro. Finger print is added through STB. I think you are unware of the people who don't use Airtel STB itself. But use different STB, hake and tune to Airtel network. It's still happening. Please browse YouTube. There are many videos. I don't know if I can share the video link here. Can send the link in DM if you want. Then why do you think they are so specific in adding the logo in the uplink centre instead of using STB for branding ? It's much easier to add it in STB. Operator logo helps them to identify the network.No buddy. Logo positioning has nothing yo do with stopping or avoiding piracy of signals. For that purpose there exists fingerprinting which is the unique code which is flashed after certain intervals on set top boxes of a subscriber which helps operators detect the owner/box details/address of where box being used incase same is used for illegally using a channel feed for airing on any other platform / place.
I have never seen this in any channel in Airtel except Vijay Takkar (LCN 822).Also broadcasters have such unique fingerprinting which is shown after regular intervals on the IRD/encoder boxes placed at operators end and which we can also see on that TV channel. This helps broadcaster find out if a certain IRD box/signals of a channel from a particular operator r being used for piracy.
