Abstract:
1. A communication method of transmitting video data, using a system for transmitting the video data including a predetermined number of bits as a unit from a source device to a sink device in sync with pixel clock and using individual first transmission lines for respective color data or for luminance and color-difference signals and a second transmission line for the pixel clock, the communication method comprising: preparing video data for three-dimensional display including the video data for a left eye and the video data for a right eye, as the video data transmitted from the source device to the sink device; forming the video data for the left eye and the video data for the right eye including the predetermined number of bits per pixel, respectively; adding one of the video data for the left eye and the video data for the right eye to the other thereof per pixel, the other video data including the predetermined number of bits, wherein the adding includes arranging the one of the video data and the other video data of one pixel, respectively, as a first half and a second half of a transmission period of one pixel; forming the video data of one pixel including twice the predetermined number of bits and transmitting the video data at a timing in sync with the pixel clock; and transmitting the video data for three-dimensional display from the source device to the sink device on the individual first transmission lines and the pixel clock on the second transmission line, the pixel clock having a rate set in accordance with the transmission period, wherein an indication of whether or not the video data is intended for three-dimensional display is transmitted over a display data channel of an HDMI (high-definition multimedia interface), wherein the video data formed by adding one of the video data for the left eye and the video data for the right eye to the other thereof per pixel is transmitted from the source device to the sink device via a single HDMI cable.
