Abstract:
1. A source device comprising: a processor; a persistent storage having stored therein at least a first set of sink device verification parameters derived from a legacy version of a secure proprietary resource and a second set of sink device verification parameters derived from a newer version of the secure proprietary resource, wherein the secure proprietary resource is utilized to enable the prevention of content transmission from the source device to a sink device that has not been authorized to receive such content; a first communication interface coupled to the processor by which one or more sink devices can connect to the source device and which receives, from a connected sink device, handshake credentials, including sink device identifying data, during an initial handshake with the connected sink device; authentication firmware that executes on the processor and which performs the initial handshake with a connected sink device and, in response to receiving from the sink device a set of handshake credentials that include verifiable handshake data that was derived from at least one of the secure proprietary resource, automatically approves the connected sink device to receive content from the source device; and content delivery firmware that executes on the processor and which determines a service tier for content delivery to an approved, connected sink device based on the version of the secure proprietary resource from which the verified handshake data of the connected sink device was derived; wherein at least one of (a) content protected via the new version of the secure proprietary resource and (b) certain advanced features of all content are prevented from being transmitted to the approved, connected sink device in response to the service tier for content delivery being a first service tier associated with the legacy version of the secure proprietary resource.
