Information processing
First Claim
1. An information processor for rendering input data compatible with standard video recording and/or display equipment, said information processor comprising means for digitizing the input data over periods which are synchronous with the fields of a standard video signal, memory means for storing the digitized data and for releasing stored digitized data in correspondence with the line scan of a standard video monitor, said memory means having two halves which correspond to the interlaced fields of a standard video signal and being so arranged that one half is filled while the other is emptied, and means for converting the released stored digitized data into video luminance signals.

Abstract
An information processor for rendering input data compatible with standard video recording and/or display equipment, comprising means for digitizing the input data over periods which are synchronous with the fields of a standard video signal, a store adapted to store the digitized data and release stored digitized data in correspondence with the line scan of a standard video monitor, the store having two halves which correspond to the interlaced fields of a standard video signal and being so arranged that one half is filled while the other is emptied, and means for converting the released stored digitized data into video luminance signals.
The input data signals may be in digital or analogue form.
A second stage which reconstitutes the recorded data also is described.
