ABSTRACT:
The present invention is a method and apparatus for interfacing a host and a conditional access circuit to a digital device. A switching circuit is coupled to the host and the conditional access circuit to switch input streams into output streams. The input streams include a host stream from the host and the output streams include an interface output stream. An interface circuit is coupled to the steering circuit and the digital device to transfer the interface output stream to the digital device.
