Abstract
Conventionally, transmission of television images is performed by Raster scanning. To avoid the problems associated with flyback, and the limiting of Raster scanning to image scanning standards it is proposed to transmit images by scanning along a locus defined by a fractal curve. A Peano curve is particularly suitable. Image resolution may be varied by varying the order of curve used to scan the image. Smoothing of a curve of a given order results in a graceful degradation to a curve of lower order so that the image created by a given order is still recognizable when displayed by a lower or higher order.
