<p><P>PROBLEM TO BE SOLVED: To provide an image data transmission system, image data receiving apparatus and image data transmitting apparatus in which video can be immediately viewed, even when a power source is turned on or a channel (image content) to be viewed is switched, while ensuring the quality of a video signal when a plurality of image data receiving apparatuses are to receive one and the same image data transmitted by the image data transmitting apparatus. <P>SOLUTION: In the image data transmitting apparatus, each of error correction image data block B' containing the same image data as an image data block B is sequentially transmitted at a transmission timing earlier than a transmission timing of the image data block B by a predetermined time. In the image data receiving apparatus, if a transmission error is completely corrected before starting reproducing a video signal using the image data block B, processing is switched to video signal reproduction using the error correction image data block B'. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
