摘要

A data generating apparatus 100 includes: an acquiring unit 101 configured to acquire a frame image; a setting unit 109 configured to set prohibition information showing a region on the frame image in which superimposition of an additional image is prohibited, the prohibition information being used when a playback apparatus superimposes the additional image on the frame image for playback; and a multiplexing unit 104 configured to multiplex the frame image and the prohibition information to generate data. A receiving apparatus 400 includes: a receiving unit 401 configured to receive data having been generated by multiplexing the frame image and the prohibition information; a separating unit 402 configured to separate the frame image and the prohibition information from the data; an acquiring unit 409 configured to acquire the additional image; and a superimposing unit 407 configured to superimpose the additional image on the frame image based on the prohibition information.
