    摘要: A method and apparatus for generating a visible signal to enable a user to confirm the amount of data transmission in Visible Light Communication (VLC) are provided. The apparatus previously acquires amount information of data which is to transmit or receive, and acquires the ratio of the amount of data transmitted to a receiving-side VLC device from a transmitting VLC device or the amount of data transmitted from the transmitting-side VLC device received by the receiving VLC device to the total amount of data. The apparatus determines a visible light output pattern corresponding to the data ratio and generates visible light of the determined output pattern.

    摘要: A peer-to-peer communication method for NFC is provided. A link-level security is started by exchanging a link-level security request and a link-level security response between an initiator terminal and a target terminal, then transmission data are encrypted at link-level security layers of the initiator terminal and the target terminal, and the encrypted data are exchanged between the initiator terminal and the target terminal. The link-level security is released by exchanging a link-level security release request and a link-level security release response between the initiator terminal and the target terminal.

    摘要: An optical receiver for visible light communication includes a lens system for converging visible light for light communication and an optical filter for passing converged visible light to the optical receiver. A photoelectric transmission device detects data from visible light for light communication in a VLC system. An optical filter is positioned between the lens system and the photoelectric transmission device, the optical filter having a first film for transmitting visible light and a second film arranged/grown around the first film to transmit ultraviolet rays or infrared rays. A first optical detects data from visible light passing through the first film of the optical filter. A second optical detector detects the intensity of light transmitting the second film. The encoding, encoding rate or intensity of the optical transmitted signal can be adjusted in response to the detection of at least the second optical detector.
