Title: The Innovations of Karoly Budai
Introduction
Karoly Budai is a notable inventor based in Danbury, CT (US). He has made significant contributions to the field of video signal processing, holding a total of 3 patents. His work focuses on enhancing video signals to prevent unauthorized copying and improve display quality.
Latest Patents
One of Budai's latest patents is titled "Horizontal pulse augmentation of a video signal." This invention involves adding augmenting pulses to the horizontal sync pulse intervals of a video signal. The purpose is to prevent a copy of the modified video signal from being satisfactorily displayed. The magnitude of these augmenting pulses is carefully chosen to ensure that the modified signal can be displayed without distortion. When recorded and reproduced by a typical VCR, the augmenting pulses are attenuated, leading to issues in detecting horizontal sync in the copied signal, resulting in an unsatisfactory display.
Another significant patent is "Anti-copying video signal processing." This invention prevents counting circuitry in the vertical synchronizing circuit of a video receiver from generating vertical control signals at a fixed periodicity. This is achieved when the transmitted video signal exhibits a changing field interval that varies above and below the standard period. The invention deletes at least one vertical pulse and several equalizing pulses in the post-equalizing period of each field interval. To minimize disturbances in the displayed video picture, the timing of the first vertical pulse in selected field intervals is shifted.
