<p>A transmitting device (100) of present invention includes a framing portion (104) that 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, and an encoder (106) that encodes an output from the framing portion such that the video image signal is transmitted to a receiving device, when the framing portion (104) is compatible with a progressive image, the framing portion (104) produces the output after swapping the data positioned in the different area between two consecutive frames, and when the framing portion (104) is compatible with an interlaced image, the framing portion (104) produces the output without performing the swapping.
