What is "Crypt"?
Crypt Encryption Mode
This shows the encryption method(s) in use by the channel.
Encrypted channels are deliberately scrambled, so that a special decryption device is needed to watch - or listen - to programming. In analogue technology, encrypting a television channel is mostly done by putting the video lines into a different order.
Digital transmissions can be encrypted in a wide variety of ways. Usually, a special card (similar in size to a credit card) has to be inserted into a satellite receiver, often in conjunction with a Conditional Access Module (CAM). This card contains the code to decrypt signal.
Those cards are only available from the programmer, in most cases at a price (pay-tv). In some cases the cards are available free to certain citizens only, to restrict an otherwise free channel's availability to certain geographical areas.
