ABSTRACT:
A method and apparatus for compression encoding successive input images into a plurality of sync blocks which are sequentially recorded on a record carrier, comprises digitally processing each of the input images in accordance with a first image compression encoding technique so as to provide a first digital signal representative of a low resolution version of each of the input images. The input images are also digitally processed in accordance with a second image compression encoding technique which is different from the first image compression encoding technique so as to provide a second digital signal representative of a higher resolution version of each of the input images. Consecutive portions of both of the first and second digital signals are combined into sequential sync blocks which are then sequentially recorded on a record carrier.
