A signal transmission apparatus includes: a vertical rectangular region sampling-out control section that obtains vertical rectangular regions, repeatedly performs a process where pixel samples read out from each line of class images are mapped to each line of video data regions of sub-images, maps pixel samples to each line of the video data regions, and repeatedly maps pixel samples to the next line; a line sampling-out control section that samples out the pixel samples every other line from each line of the sub-images to which the pixel samples have been mapped, so as to generate an interlace signal; a word sampling-out control section that samples out for each word the pixel samples which have been sampled out for each line so as to be mapped to video data regions of an HD-SDI prescribed by the SMPTE 435-2; and a readout control section that outputs the HD-SDI.
