Filed:

May 30, 1995

Appl. No.:

8/453622

Inventors:

Phillip P. Bennett - Portola Valley CA
Edwin E. Flores - San Bruno CA

Assignee:

Scitex Corporation Ltd. - Herzlia B.

International Classification:

G11B 5012

US Classification:

360137

Abstract:

A disk drive that is the product of modifying a standard computer disk drive to read and write data in parallel with all of its transducer heads at once, rather than serially with only one head at a time. A method and apparatus are disclosed for protecting the disk drive's platters from damage and contamination while working on the interior of the disk drive case. The apparatus includes a hinged cover that replaces a conventional disk drive cover while work is being performed on circuitry within the disk drive case. The hinged cover seals off the platters and the inside of the disk drive case except for the circuitry being worked on.

International Classification:

US Classification:

Abstract:

A TV video signal synchronization signal system enables a video device such as a digital special effects system to operate synchronously in response to an input video signal and still produce an output video signal synchronized to a television studio locking reference signal. The video device and the synchronization signal generating subsystem thereof operate in response to a pixel rate clock of approximately 70 ns and in response to a phase command to generate timing for the horizontal sync pulse, color burst signal and video data of the output video signal. The output color burst signal remains phase locked to the locking reference signal with output gating being responsive to the phase command. A ROM interpolator provides subpixel accuracy for the output horizontal sync pulse while output line buffering and interpolation permits the output video data to the phase matched to the reference master sync signal. The entire video system thus operates synchronously with the input video signal to avoid noise interference problems which result from multiple phase clock signals while generating a composite output video signal that is properly phase synchronized with a studio locking reference signal.

Assignee:

Micro Consultants Limited - Berkshire

International Classification:

H04N 576
H04N 592

US Classification:

358160

Abstract:

A digital picture storage system with various facilities including size change. The system includes real time frame storage and a non-real time store expediently provided as disc storage. The size change mechanism has access to the data in the non-real time domain to allow size change techniques to be used which are more readily realizable.

International Classification:

H04N 9535

US Classification:

358 22

Abstract:

A spatial transformation system includes a processing system for each component of an input video signal. The processing systems respond to operator commands entered through a control panel to provide spatial transformation such as enlargement, reduction, translation, and three-dimensional perspective rotation. The system further includes a key processing system connected to operate in tandem with the video component processing systems to transform an input key signal indicating a portion of a video image to be viewed in exactly the same way as the image defined by the input video signal. The output key signal thus exactly defines the same portions of the output video image as it did for the input video image notwithstanding significant changes in image shape which may result from a selected given spatial transformation. A proportional switcher is connected to receive a transformed image from the spatial transformation system on one channel and a second video image on a second channel and mix them in proportion to the magnitude of the key signal generated by the key processing system. The image from one channel may thus be smoothly blended into the image of the other input channel to eliminate aliasing along a boundary between two adjacent images.

US Classification:

358 11

Abstract:

A video sample rate converter for converting decoded SMPTE D2 interleaved component video to SMPTE D1 interleaved component video includes a single modified multi-tap finite impulse response ("FIR") digital filter which alternately functions as a data selector and two-point linear interpolator, and as a four-point polyphase interpolator. The FIR filter uses time variant switched filter coefficients and a selectively inhibited output clock signal.
