Abstract:
1. A computer-implemented method comprising: identifying, at a computing device, a main port serving as an active port facilitating communication of media content between a transmitting device and a receiving device, the main port associated with a main pipe and a first High-Definition Content Protection (HDCP) engine at the computing device; identifying, at the computing device, roving ports as inactive ports in idle mode serving as backup ports to the active port, the roving ports associated with roving pipes and a second HDCP engine, wherein the first and second HDCP engines are synchronized to the transmitting device; pre-authenticating, at the computing device, the identified roving ports, wherein pre-authentication of the identified roving ports is performed simultaneously while the roving ports remain inactive and the main port serves as the active port, wherein data relating to the roving ports collected during pre-authentication process is stored and used in order to keep the roving ports authenticated to ensure that any of the roving ports is ready to replace the main port to serve as the active port; and in response to a port switch, on-demand and seamlessly, replacing the main port with a pre-authenticated roving port to serve as the main and active port.
