A possible method of recording and replaying video with sound-in-syncs on video tape recorders

摘要

A method of recording and replaying a video signal with sound-in-syncs has been proposed and experimental equipment has been constructed to investigate the proposed method, with encouraging results. Tests showed the method to be feasible, but more work on error-detection and error-correction would be required before a practical system could be constructed for general use. It is likely that, with such protection, a separate high-quality sound channel could be accommodated on video-tape recorders without detriment to the video signal.
