One argument that the pro-encryption camp is using is that it provides Integrity to TV. Encryption provides an important quality, such that it prevents someone from interfering with a broadcast and broadcasting their own, psuedo authoritative, pirate signal.
This can also be achieved with signing. These arguments are spurious. Please comment to oppose encryption.
Fine. Let's agree to that -- encrypt everything and publish all of the decryption keys. Make a huge fine to encrypt anything with a non-published decryption key.
That sounds like something you could lawyer out of or wait until the enforcement authority focuses on something else. Encryption here only benefits the content owner and comes at the cost of the user. There's no value here in adding encryption.
Hasn't happened since digital TV. It's more likely that a broadcasting station is hacked and the stream is hijacked there rather than hijacked using a rogue transmitter.
