Biss

BISS is a system used on private video feeds shared via satellite between organisations. Organisations like the EBU/Eurovision use BISS to distribute their content to partners securely.

Simple BISS works by the two parties sharing a common key, the sender then encrypts the broadcast and the receiver uses the key to decode that video.

There is also an enterprise version of BISS where the broadcaster will encrypt the stream and the system will send the content key using secret means to decoders who are pre-registered with the BISS headend.

Normally consumers wouldn’t be exposed to BISS.
