About DCS Corp
DCS Copy Protection Ltd is a UK company that licenses proprietary content protection technology. It is a direct competitor to Rovi (formerly Macrovision) in the field of analogue copy protection. DCS Copy Protection Ltd is a wholly owned subsidiary of Echostar Corporation. The DCS Copy Protection technology claims to block the copying of analogue video outputs from digital video sources (Digital TV Set Top Boxes, Blu-ray players, etc), modifying the video signal so that DVD recorders, VHS machines etc cannot copy it, while TV sets can display the protected content as normal.
