Title: METHOD FOR GENERATING A COMMUNICATION LINK BETWEEN DEVICES, AND APPARATUS FOR SAME
Abstract:
One embodiment of the present invention relates to a method for generating a communication link between devices, comprising the steps of transmitting, to a second device, a connection request frame which contains first encryption selection information for selecting an encryption scheme to be applied to the content to be transmitted between devices from between a Digital Transmission Content Protection (DTCP) scheme or a High-bandwidth Digital Content Protection (HDCP) scheme, and which makes a request for establishing of communication link; and receiving, from the second device, a connection response frame which contains second encryption selection information for selecting an encryption scheme identical to the encryption scheme selected by said connection request frame, and which approves the request for establishing a communication link made by said connection request frame.
