Abstract: In some aspects, the disclosure is directed to methods and systems for controlling a set top box remotely and monitoring its display output.

Abstract: A system and method are disclosed for provisioning IP features in a system-on-chip. A plurality of identical chips are fabricated, each of which is capable of have a number of features enabled or disabled. As a default, all features are disabled.

The license information is encrypted using a key already known to the chip, and sent to the manufacturer. The chip receives the license information during provisioning, extracts relevant provisioning information using the key, and a secure processing system provisions the relevant features. Log information is generated to allow the IP owner to verify license compliance.
