Abstract: Systems, methods, and devices for processing video data are disclosed. Some examples include a content receiver including an unsecure processor and an unsecure memory coupled to the unsecure processor. The example includes content protection zone hardware including a secure memory and an input for receiving content. The input coupled to the content protection zone hardware, wherein the content protection zone hardware determines if the received content is secure or unsecure and directs secure content to the secure memory and unsecure content to the unsecure memory.

Abstract: Systems and methods for external access detection and recovery in a subsystem of a system-on-a-chip (SoC) in a portable computing device (PCD) are presented. In operation, a subsystem of the SoC is operated in an internal mode independently of the SoC while the SoC is in a low power state, such as a non-functional or zero power state or mode. The subsystem comprises a processor in communication with a memory, a sensor, and a monitor module. The monitor module detects when the processor of the subsystem requests access to a component external to the subsystem. In response to this detected request, the SoC is caused to enter into a full power state or mode, and the subsystem is caused to exit the internal mode of operation.
