I Never had to use a code to use Airplay TV and now its asking for a code. What is all that about? Censorship?

Hello Apple users. I am trying to use my Apple TV Airplay and it used to be easy as clicking the Airplay TV Icon but now they are asking for a code. Every time I put a "code" which appears on my TV into the wizard box on my Apple lap top it rejects the very code it gave me. Whats going on? Is Apple blocking content?
