Abstract
In an improved image data transmission system, an image data partitioning unit is provided at the transmitter section to partition an input image data into a predetermined number of picture elements (blocks) so that same picture elements of the image data can be subject to source image encoding and forward error correction encoding. At the receiver section, picture elements in each of the data blocks are subject to error correction decoding and source image decoding. The receiver section is provided with an image data interpolator which works, when an transmission error is detected, to interpolate with a substitution data the data in a block in which the error has been detected or data in other block to which the error has been propagated as it is. After the interpolation, a reconstructed image data is delivered.
