The streamers now offer the possibility to decrypt BISS encrypted streams. BISS, the so-called "Basic Interoperable Scrambling System" is used to encrypt satellite signals for transmission. It was developed by the EBU and a hardware consortium to achieve better interoperability between different manufacturers of encoders and satellite receivers.
Until the introduction of BISS it was only possible to use proprietary encryption systems or to transmit unencrypted. Of course with the big disadvantage that then anyone with the correct receiver settings could receive and decode the signal. After activating a license key, the U 148-X can now receive, decode and process these BISS encrypted streams. The decryption keys are entered globally for the complete transport stream or service-based separately for each program.
