<p>PURPOSE: A transmitting device, a receiving device, and a communication system are provided to secure the compatibility of both an interlaced image and a progressive image. CONSTITUTION: A framing portion(104) outputs a video image signal which is acquired per frame after extracting data of the video image signal at every predetermined number of lines in a vertical direction within a frame and positioning the data in a different area within the same frame. An encoder(106) encodes an output from the framing portion such that the video image signal is transmitted to a receiving device when the framing portion is compatible with a progressive image. The framing portion produces the output after swapping the data positioned in the different area between two consecutive frames. When the framing portion is compatible with an interlaced image, the framing portion produces the output without performing the swap.</p> |
