Title: Werner Staude: Innovator in Digital Signal Processing
Introduction
Werner Staude is a notable inventor based in Reinheim, Germany. He has made significant contributions to the field of digital signal processing, particularly in the areas of error detection and correction in digital television signals. With a total of 2 patents, his work has had a lasting impact on the technology used in modern digital communications.
Latest Patents
One of Staude's latest patents is focused on the detection and verification of lapses or shifts of synchronization words in PCM data. This invention involves a counter that operates at the PCM sampling frequency to count the normal minimum period between successive synchronization words in a data stream. A subsequent 'window' allows for the detection of another synchronization word, producing a check signal. If the synchronization word is not detected, the data for the next period is marked as dubious. A second counter counts out twice the minimum normal interval, and the appearance of a synchronization word in the following window produces a verification signal. This system effectively marks erroneous data and ensures the integrity of the data stream.
Another significant patent by Staude is a method and apparatus for concealing errors in a digital television signal. This invention utilizes two delay circuits to create three places where shift registers can be connected for stepping digital signals at picture point intervals. This allows for a two-dimensional array of neighboring picture points to be used for correcting the signal of a central picture point if it is found to be defective. The system employs an error-correcting circuit to represent defective picture points with a null value, and a read-only memory controls the selection of digital signal pairs for averaging to provide an output signal. This innovative approach ensures consistent processing times for all picture points, regardless of whether the signal is defective.
