Consumers can soon stream cable TV over home networks, DRM

CableLabs has announced its approval of a new streaming protocol called DTCP-IP (Digital Transmission Copy Protection), allowing consumers to stream cable TV programming across their home networks for viewing on devices that aren't attached to a set-top box. The protocol will use DRM to lock down content to ensure that it doesn't leave the cable subscribers' homes. To enforce the number one restriction content providers request, content that cannot be copied, DTCP-IP will use the "same level of protection, functionality, and treatment of content" that exists in the AACS DRM technology. That means that the movie studios will be able to revoke a device's keys in much the same way that they can for HD DVD and Blu-ray players.

"The agreement we reached today addresses the highly complex concerns raised by the affected parties—cable, content, and consumer electronics—and brings benefits to consumers. Working together, we agreed on solutions that meet our respective business needs and serve the interests of consumers and content providers," said Dr. Richard R. Green, CEO of CableLabs.
