An image data transfer system constructed of an image data transfer unit, transmission medium and image data reproduction unit. In the image data transfer unit, an input video signal is transformed into image data through sampling and quantization, the image data are coded in a predetermined image coding method, and transferred to the transmission medium. In the image data reproduction unit, the coded data transferred by the transmission medium are decoded in a predetermined image decoding method, the original video signal is restored from the decoded data. A data transfer speed and transfer scheme are selected such that the total coded data amount for the input video signal over a predetermined time duration becomes equal to or smaller than a transferable data amount determined by a data transfer speed from the transmission medium to the image data reproduction unit and by the predetermined time duration. Data transfer information on the selected data transfer speed or information on the transfer scheme is transferred to the transmission medium along with the coded data. |
