Abstract
A system-on-a-chip (SoC) to process digital audio-video content includes one or more input/output (I/O) interfaces to transmit the digital audio-video content to corresponding I/O devices coupled to the SoC and to receive the digital audio-video content from the corresponding I/O devices. The SoC also includes a cryptographic engine to encrypt the digital audio-video content being transmitted via the I/O interfaces to the corresponding I/O devices and to decrypt the digital audio-video content received via the I/O interfaces from the corresponding I/O devices.
