An embodiment of the present invention relates to physical interfaces, especially those used on consumer electronics devices. A processor, in which an embodiment of the disclosed invention is deployed, includes a physical interface for connecting to and communicating with a peripheral device, the peripheral device being configured to operate according to a standard communications protocol or to a different protocol which is adapted to have a more bandwidth-efficient performance. The processor detects which of the two protocols the attached peripheral device uses and configures the physical interface to operate according to the detected protocol. An embodiment of the invention allows for new, bandwidth-efficient communications protocols to be executed across existing standardized physical interface hardware, thereby allowing for easier acceptance of the new protocols within the consumer electronics industry. Bandwidth-efficient communications protocols advantageously allow for more convenient transfer of media content or for big-data applications to be more conveniently handled.

Smart card interface

Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control word that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The secure processor may connect to the device via a standard connection, such as via a USB 3.0 connector.
