Oak Orion
From Wikipedia, the free encyclopedia
The Oak Orion scrambling system was a form of television encryption developed by Oak Industries in the early 1980s.
It was mainly used for encrypting the satellite feeds of American and Canadian television services transmitted by Cancom via the Anik satellites, first on Anik B, and later on Anik D1 and Anik E2, beginning in 1982. Virtually all services uplinked by Cancom were encrypted via this method, with the exception of one channel, First Choice, which chose to use the Videocipher system adopted by U.S. programmers during the late 1980s-early 1990s. First Choice later switched to Orion.
This encrpytion system was discontinued by the mid-1990s in favor of digital delivery.
