  • Still store system and method with simple image access
    Patent number: 5451982
    Abstract: A digital still store system (10) receives composite digital 4:2:2 D1 video signal inputs in parallel at (12) or serially at (14). The signals are supplied in component form selectively to one of framestores (18) and (20). The component signals are supplied from the framestores (18) and (20) to hard disks (22) through a buffer store (24) and disk input/output (I/O) circuits (26). Each of the hard disks (22) stores still video images as either 525 or 625 line digital frames for either NTSC or PAL composite signal inputs and outputs. Y and C fields of component video signal information are supplied from the hard disks (22) through the buffer store (24) and one of the frame stores 18 and 20 to a compositor (28) for output as digital 4:2:2 video signals. The buffer store (24) obtains the video signal fields for either full size images or 1/4 size images, when an array for browsing and selection is desired.

  • YIQ Computer graphics system
    Patent number: 4564915
    Abstract: A YIQ computer graphics system includes a data processing system having a data tablet for receiving inputs from an artist and a video processing system connected to the data processing system. The video processing system includes a two component expandable frame store with the first component storing video intensity information for each pixel of a visual image and with the second component storing two video color components each for one-half of the visual image.

  • Circuit for generating a digital, deleted data, blinking cross signal which is stored in a deleted track and selectively displayed for detection
    Patent number: 4130842
    Abstract: A circuit for generating a deleted data signal, which is reproduced as a blinking cross in a television picture, to provide thereby visual indication that a storage location in a video frame store is unoccupied, and available for recording therein. The blinking effect is created by interlacing one diagonal line generated in one field with an opposing diagonal line generated in a second field at the 30 Hertz frame rate. The deleted data signal corresponding to the blinking cross is recorded in the deleted track, e.g., the still location thereof, whereby the store can be interrogated and the deleted data signal suitably displayed to indicate the availability and location of the track for subsequent recording.
