Abstract: An apparatus and methods are disclosed for a bidirectional front-end circuit included within a system on chip (SoC). The bidirectional front-end circuit includes a differential bidirectional terminal for receiving and transmitting signals. The bidirectional front-end circuit is configured to provide a first communication path between a first controller and a connector through the differential bidirectional terminal when operating in a first mode. And, the bidirectional front-end circuit is reconfigured to provide a second communication path between a second controller and the connector through the differential bidirectional terminal when operating in a second mode.

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.
