<p>According to the present invention, when video data of, for example, a real moving picture is transmitted, the video data is data-compressed (12), data-encoded (14) and transmitted (15,16) while the combination of the compressing ratio of the video data and the encoding ratio of the video data is varied in response to a condition of the transmission path. Therefore, regardless of the condition of the transmission path, video data of the best quality can be transmitted at a constant transmitting speed.</p> |
