Digital Transmission Copy Protection Formed by the merging of two technical approaches originally proposed to the CPTWGs DTDG, the Digital Transmission Copy Protection ("DTCP") system is designed to protect content throughout digital transmission from one consumer device to a different shopper system. Power cables are used for bulk transmission of alternating and direct present energy, particularly using excessive-voltage cable. An electric cable acts as transportation for energy or sign betwee...
