Title: The Innovative Contributions of Charles E. Garvin
Introduction
Charles E. Garvin is a notable inventor based in San Francisco, CA. He has made significant contributions to the field of audio technology, particularly in the area of high-speed reproduction of musical recordings. His innovative approach has paved the way for advancements in data processing systems used in audio programs.
Latest Patents
Garvin holds a patent for a "High-speed reproduction facility for audio programs." This invention utilizes a data processing system designed for high-speed reproduction of musical recordings at point-of-sale terminals. The system employs optical CD music ROM banks of master programs that are prerecorded using a Dolby ADM (adaptive delta modulated) technique. This method condenses the information content, allowing for higher data throughput during high-speed reproduction. The invention includes a 'premastering' process that involves a special multiplexer board, which interfaces Dolby ADM digital audio data with conventional data processing systems. This board performs data blocking and writes a unique sync code directly into the data block. Additionally, the system catalogs and edits the blocked digital audio, placing encrypted catalog, pricing, and other information in the data file representing the music. The data file is then sent to a conventional 16-bit PCM file writer to create encoded CD music ROMs containing the ADM data that represents the encoded audio program.
