Patent ID: 8896663

Claim:
A transmitting device, comprising: a framing portion that outputs a video image signal, which is acquired per frame, wherein the video image signal is a signal of one of a left eye video image and a right eye video image that form a three-dimensional image, has data extracted at every predetermined number of lines in a vertical direction, positions the extracted data in a different area in the same frame at every such predetermined number of lines, and inserts information specifying a chosen area selected from among a plurality of different areas within the frame with respect to data of the frame in which the left eye video image data and the right eye video image data are merged in which the chosen area is specified by specifying coordinates of a start position and an end position thereof; and an encoder that encodes an output from the framing portion such that the video image signal is transmitted to a receiving device, wherein 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, and when the framing portion is compatible with an interlaced image, the framing portion produces the output without performing the swapping.
