Abstract:
1. A transmitter comprising: a multiplexer configured to load a signal value of an image signal of a first resolution, a signal value of an On Screen Display (OSD) configured to be superimposed on the image signal, blend information of the OSD and depth information of the OSD at a first plurality of positions on a transmission signal comprising a second resolution larger than the first resolution, and to transmit the transmission signal to a receiver; and a first sorter configured to sort the blend information of the OSD and the depth information of the OSD, to assign the blend information of the OSD at third positions in the transmission signal on a first signal line and to assign the depth information of the OSD at the third positions in the transmission signal on a second signal line different from the first signal line, wherein the multiplexer is configured to load: the signal value of the image signal at a first position on the transmission signal, the signal value of the OSD at a second position on the transmission signal, the second position being different from the first position, and the depth information of the OSD at a third position on the transmission signal, the third position being different from the first position and the second position, wherein the first sorter is configured to divide the blend information of the OSD and the depth information of the OSD into first information and second information, the first information comprising the blend information of the OSD and the depth information of the OSD for even lines in an image, and the second information comprising the blend information of the OSD and the depth information of the OSD for odd lines in the image, and wherein the multiplexer is configured to assign the first information and the second information at separate positions in the transmission signal.
