US 5,627,691 A · Character data recording and reproducing system for a VCR

Abstract

A character editing system for a VCR, comprising a control circuit for performing on-screen display control and recording control operations for character data in a character editing mode; a character recording circuit for encoding character data, demodulating the encoded data and recording the demodulated data on a selected one of stereo audio tracks of a video tape under a control of the control circuit; an audio reproducing circuit for detecting audio signals and character data from the audio tracks and outputting the detected audio signals to speakers; a video reproducing circuit for detecting video signals from a video track of the video tape and demodulating the detected video signals; and a character output circuit for outputting the character data which is to be recorded or the character data which is reproduced by the audio reproducing circuit, placing the data on the reproduced video signal from the video reproducing circuit, under a control of the control circuit. The character information signal is digitized and the digitized signal is recorded on the audio track of the video tape. Therefore, the character information can be viewed distinctly during playback of the VCR and degradation of the character edited portion of a video picture during playback of the VCR can be prevented, thereby assuring clarity of the video picture.
