Data placement technology on tape for digital video tape recorder suitable for high-speed image playback

摘要

A method and apparatus for compressively coding successive input images into a plurality of sync blocks sequentially recorded on an input record carrier, comprising the steps of: digitally processing each of said input images in accordance with a first image compression encoding technique, And a first digital signal representing a low-resolution version of each of the first and second digital signals. The input images are also digitally processed according to a second image compression encoding technique different from the first image compression encoding technique to provide a second digital signal representative of a higher resolution version of each of the input images. The successive portions of the first and second digital signals are then combined into sequential sync blocks that are sequentially written on the record carrier. On average, the first digital signal of each sync block represents the complete horizontal line of the input image.
