Latest Patents
Among his latest patents are innovations related to video-signal processing systems and methods. One notable invention focuses on a video-signal processing system designed to recover from loss of synchronization while encrypting and decrypting video signals. This invention includes an encryption processing unit that unencrypts a frame number obtained from counting vertical control pulses of a video signal. It transmits this frame number alongside an unencrypted frame number and an H/V control pulse. Additionally, a decryption processing unit decrypts the encrypted frame number to generate a corresponding frame number, which is then supplied to a correcting unit. This correcting unit generates a pseudo load pulse when discrepancies occur between the frame numbers, ensuring reliable video display.
Another significant patent involves a driving apparatus for plasma addressed liquid crystal display devices. This invention features a reference voltage selection D/A converter that applies a driving voltage to a transparent scanning electrode group. It also includes a common anode inversion driving voltage generator and a contrast reduction adjustor, which work together to maintain optimal display quality.
