Title:
VIDEO SIGNAL RECORDING AND REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JPS6331287
Kind Code:
A
Abstract:
PURPOSE:To obtain a reproduced picture having no deterioration in resolution by vector adding respective dynamic vectors for plural fields in the respective parts of a picture according to a reproducing mode, feeding to a muse decoder and correcting a movement. CONSTITUTION:At the time of a special reproduction such as a double speed, a triple speed, a reverse, a control signal reproduced from a fixed head 115 is demodulated according to the mode in a reproduced control signal processing circuit. A signal reproduced from rotating heads 116, 117 is demodulated in a reproduced video signal processing circuit 121. The position relation of a track and a video signal is cleared in a track detection circuit 123 and outputted to a terminal 150. The dynamic vector in the control signal is inputted to a dynamic vector addition circuit 122 and the addition of the vector is performed by the use of a reproduced dynamic vector. The control signal of the dynamic vector is inputted to the dynamic vector setting circuit 140 of the muse decoder 103. The dynamic vector setting circuit 140 changes the dynamic vector outputted from terminals 136, 137 even in one field video signal.
