Abstract:
A communication system that transmits a plurality of pieces of video data to be synthesized and output to a plurality of output apparatus after dividing into a plurality of pieces of video having different qualities, in which, in a case where the plurality of pieces of video data are transmitted to the plurality of apparatus to synthesize and output the data, it is so configured that a difference in video quality is made so as not to be remarkable even when each apparatus cannot receive the video data having the same quality, wherein a reception state of the video data in each output apparatus of the plurality of output apparatus is determined and the quality of the video data to be synthesized and output is decided according to the reception state of the video data in each output apparatus, thereby outputting the video data having thus decided quality.
