Abstract:
A method for recording, reproducing, and processing video image information comprising: (a) generating a plurality of groups of video image information signals, each group defining a single frame image consisting of multiple line scans across the frame and including line and frame synchronization signals, wherein each group is suitable for controlling and synchronizing the modulation of a picture-generating write-beam of a video monitor-screen, (b) recording said groups of image information signals on different recording locations of an addressable multi-track magnetic storage member by: (1) passing said groups of image information signals to a magnetic head, (2) effecting relative movement between said magnetic recording head and said magnetic storage member, and (3) controlling said head to magnetically scan and record select groups of signals at select recording locations of said storage members (c) recording respective first digital codes on said magnetic storage member, each of said first digital codes indicating the location of a respective group of the image information signals recorded on a respective select recording location of the storage member, (d) recording second digital codes on said magnetic storage member, said second digital codes controlling an image modification to be made to a group of image information signals recorded on said storage member defining a selected area within the image, (e) thereafter employing said first digital codes to locate a select group of image information signals recorded on said storage member defining a frame, and (f) thereafter employing said second digital codes to control a modification of the image defined by the group of image information signals defining the frame, and applying the image information signals to generate a modified image on a video monitor-screen.
