In a step toward secure links among consumer devices, industry consortium CableLabs, along with the “5C” technology companies and major Hollywood studios, announced approval of DTCP-IP (Digital Transmission Copy Protection over IP) technology for unidirectional and bidirectional digital cable products.

The technology will give cable consumers more flexibility to use advanced cable features including HDTV and video-on-demand among devices on digital home networks.

The studios—Disney, Sony, Paramount and Warner Bros.—were waiting for the Digital Transmission Licensing Administrator (DTLA), comprised of the 5C companies (Hitachi, Intel, Panasonic, Sony and Toshiba) to give cable operators shared rights in the DTLA management process. The studios also sought confirmation of the effective function of System Renewability Messages (SRMs), which enable CP administrators to revoke permission of devices to obtain protected content.

In letters to CableLabs this week passed on to the FCC, the studios said the conditions of their participation in DTCP-IP had been met.

CableLabs and DTCP officers noted that three industries—cable, Hollywood, and the consumer electronics makers—came together without government mandate to create an framework for innovation in home networking and interactive cable applications.

“DTCP-IP for home digital cable products opens the door for increased flexible use of protected digital cable content, providing opportunities for cable operators, content owners, device manufacturers and, most importantly, consumers,” said DTLA President Michael Ayers. “This represents a real advancement for the protected home entertainment network.”
