[Deep Patel]

This alphanumeric characters known as " fingerprint " are used to curb piracy and illegal connections.

When same code appears on various channels, then it's the " fingerprints " from DTH operator or MSO else if the particular fingerprint court appears only on one channel it's from particular channel.

What is learnt from various sources is , these fingerprints are uniquely send to each viewer or STB and recalled back to check the piracy or illegal viewing of channel .

Yes you are right....It differs from STB to STB, My older STB was having different series and current one is also having other Series of letters....Thank you every one for explaining that strange letter series.
