Patent ID: 8667168

Claim:
A proximity control method for transmitting content from a source node to a destination node, the method comprising: receiving or relaying a content request from the destination node; and performing, at each node in a link from the source node to the destination node, a proximity control mechanism based on whether the transmitting is in a single proximity control (SPC) domain, a mixed proximity control (MPC) domain, or a network-based service domain, and based on a physical distance with respect to a neighboring node, wherein the SPC domain comprises a relay node, the relay node functions as a switched network in the SPC domain and the relay node comprises an Audio/Video Bridge (AVB), and the AVB comprises a second Digital Transmission Content Protection (DTCP) which utilizes a first Digital Transmission Content Protection (DTCP) as an initial reference model, and an Internet Protocol (IP) comprises the first Digital Transmission Content Protection (DTCP), and the second Digital Transmission Content Protection (DTCP) comprises a standard carrying out wireless local area network communication in any one of domains of the second Digital Transmission Content Protection (DTCP) when the second Digital Transmission Content Protection (DTCP) has a proximity probability to a layer 2 (L 2 ).
