Back of a 1992 Toshiba satellite receiver with an installed VideoCipher II module

VideoCipher is a brand name of analog scrambling and de-scrambling equipment for cable and satellite television invented primarily to enforce Television receive-only (TVRO) satellite equipment to only receive TV programming on a subscription basis.

The second version of Videocipher, Videocipher II, was the primary encryption scheme used by major cable TV programmers to prevent TVRO owners from receiving free terrestrial television programming. It was especially notable due to the widespread compromise of its encryption scheme.
