This gives rightsholder control as to exactly which decoder can be used to decrypt/decode a specific feed. Only a decoder with the correct secret BISS-key will be able to decrypt a BISS-E feed. This session key is then mathematically combined internally to calculate a BISS-1 key that can decrypt the signal. The user is then sent a 16-digit hexadecimal code, which is entered as a “session key”. This is unknown to the user of the decoder. BISS-E (E for encrypted) is a variation where the decoder has stored one secret BISS-key entered by for example a rightsholder.The key is entered into both the encoder and decoder, this key then forms part of the encryption of the digital TV signal and any receiver with BISS-support with the correct key will decrypt the signal. BISS-1 transmissions are protected by a 12 digit hexadecimal “session key” that is agreed by the transmitting and receiving parties prior to transmission.There are mainly two different types of BISS encryption used: BISS was an attempt to create an “open platform” encryption system, which could be used across a range of manufacturers equipment. Proprietary encryption methods were determined by encoder manufacturers, and placed major compatibility limitations on the type of satellite receiver (IRD) that could be used for each feed.

Unencrypted satellite feeds allowed anyone with the correct equipment to view the program material.

RAS, or PowerVu), or without any encryption. Prior to its development, “ ad hoc” or “occasional use” satellite news feeds were transmitted either using proprietary encryption methods (e.g.
