Magnetic disc recording and playback of video signals - separates and processes video signal to remove jitter component followed by modification of original signal |
摘要 |
The recording and playback system for video signals on a magnetic disc (70) has a processor (200) to provide luminance, colour difference and Y reference signals. The output of the recording circuit (50) is fed to a magnetic head (60). The video input signals (Y+S) are fed to a separating stage (10) that separates the luminance (Y) and synchronising (S) components. The synchronising signal is received by a burst signal generator (20) with the output gated (30) to be added (35) to the original signal. A further signal that is generated (42) is also added in (47). The two components modify the video signal to improve the reproduction quality. USE/ADVANTAGE - Improved video signal quality even with speed fluctuations in recording medium drive.
