Patent ID: 8798049

Claim:
A transmitter, comprising: an image data generation unit generating image frames including image data regarding an obtained image; a transmission frame generation unit receiving the image frames to generate a transmission frame; and transmitting electrodes transmitting the transmission frame, wherein the transmission frame includes a plurality of control frames used for selecting pairs of receiving electrodes in a receiver and a plurality of data frames including the image frames, wherein each of the plurality of control frames includes: a first preamble used to synchronize the frames and select the receiving electrodes; a first header differentiating frame types; frame information including information on the image frames; and a switching time section for providing time required for electrode switching in the receiver, and each of the plurality of data frames includes: a second preamble synchronizing the frames; a second header differentiating the frame types; and at least a portion of the image frames; and the transmission frame generation unit includes: a data modulation unit modulating the image frames according to a preset modulation scheme; a preamble generation unit generating the first and second preambles; a header generation unit generating the first and second headers; a frame information generation unit generating the frame information; and a multiplexer multiplexing the modulated image frame, the first and second preambles, the first and second headers, and the frame information and the switching time section to generate the transmission frame.
