normal tv antenna

so far i understand, cable operator use signal to transmit the movie or anything to their sub-company for example in other island

so is there any "way" for normal tv antenna to have some channel that only cable user gets?

thanks

 

The major signal sent by the company would probably use lock an key encription which could be only decoded by having the key which wouldnt be available to the public therefore no one could decode the signal not without a huge computer and some heavy hardware

Only going of what I would percieve as happening as as happened in the UK with digital TV, the com company ntl started lock and key broadcasting in the UK,everyone could pick up the signal but only if you had the key could you watch the program,the key came in the form of a magnetic credit card which could be purchased for the same price as normal digital TV,ofcourse everyone soon realised you could use anyone elses key,the cards were copied via swiping through a standard card swiper 'available all over the internet now and the reason for the introduction of the chip in credit cards which will also soon be copied, its just bought them some time',no one paid, the company lost huge sums of money and ended up owing FIFA ect. for broadcast matches that had been payed for
