Data placement on tape for a digital video tape recorder suitable for high speed picture playback

摘要

An image carrier for storing video information including a plurality of slant tracks recorded thereon, wherein each of the tracks is characterized as including a predetermined number of sync blocks defining a predetermined track length, wherein each of the sync blocks is divided into first and second portions storing respective first and second digital signals coded therein. The first digital signal permits reconstruction of an input image during a trickplay mode of operation while the second digital signal permits reconstruction of an input image with a comparable resolution during a normal play mode of operation. On the average, the first digital signal of each sync block represents a complete scan line of the input image.
