APPARATUS AND METHOD FOR TRANSMITTING MULTIMEDIA DATA BY USING VARIABLE CODE AND TIME DIVISION SCHEME IN VISIBLE LIGHT COMMUNICATION

摘要

The present invention discloses an apparatus and method for transmitting multimedia data using a variable code and a time division scheme in visible light wireless communication. According to an embodiment of the present invention, a visible light transmission apparatus based on a light emitting diode includes a code allocation part for determining the importance of a plurality of video layer signals and assigning orthogonal division codes having different lengths to each of the plurality of video layer signals based on the importance; and a wavelength allocation part for allocating the video layer signals encoded using the orthogonal division codes to the wavelengths of a light emitting diode (LED).
