Abstract
A premises based multimedia communication system includes a source device that produces multimedia content, a rendering device that presents the multimedia content, and a premises communication network coupling the source device to the rendering device. The system certifies transfer of the multimedia content from the source device to the rendering device via the at least one premises communication network using link layer encryption operations. After certification, the system at least partially disables the link layer encryption operations for the transfer of the multimedia content from the source device to the rendering device via the at least one premises communication network. With the link layer operations are at least partially disabled, the system at least partially enables content layer encryption operations for the transfer of the multimedia content from the source device to the rendering device via the at least one premises communication network.
