摘要： In one embodiment of the present invention, a method includes authenticating an HDCP transmitting device at a first port of an HDCP receiving device. A port of the HDCP receiving device is connected to a pipe of an HDCP architecture of the HDCP receiving device at a first time. A synchronization signal is received from the HDCP transmitting device at the port of the HDCP receiving device at a second time. A loss of synchronization between the HDCP transmitting device and the HDCP receiving device is detected when the time-span between the first time and the second time is not greater than the period of time between synchronization signals sent from the HDCP transmitting device. A re-authentication is initiated between the HDCP transmitting device and the HDCP receiving device in response to detecting the loss of synchronization.
