Title: Innovations of Rudolf Wilhelm in Video Reproduction Technology.
Introduction
Rudolf Wilhelm is a notable inventor based in Klein-Gerau, Germany. He has made significant contributions to the field of video reproduction technology, holding a total of 3 patents. His work focuses on methods and systems that enhance the playback of video signals, allowing for variable speed reproduction.
Latest Patents
One of Rudolf Wilhelm's latest patents is a "Method and apparatus for the variable speed reproduction of a video." This invention addresses the challenge of reproducing video signals at selectable magnetic tape speeds that differ from the original recording speed. The method utilizes a head wheel with magnetic heads to read and store lines of picture information based on a composite signal from the magnetic tape. The line addresses are derived from a counter that synchronizes with horizontal and vertical pulses from the tape, allowing for precise control over the playback speed.
Another significant patent is the "Method and system for speed-modified reproduction of video signals." In this invention, a head wheel rotates at a constant speed while a tape is guided in a spiral path. The instantaneous position of the head wheel and tape is determined using signals from a tacho generator and cross modulation sensing. This allows for accurate line addressing and storage of video signals for subsequent reproduction at different speeds, such as slow motion or fast motion.
