KR950034236A - Editing device of V-Cal and its editing control method - Google Patents

Abstract

The present invention is applied to the missing part of the tape located between the full-erasing head and the recording start point of the tape to be recorded by adaptively controlling the driving mode of the deck in the recording mode without attaching the rotary erasing head on the head drop. The present invention relates to a V-AL editing apparatus capable of automatically erasing a signal, and a method for controlling the editing. After erasing the data, fast forward to the original recording start position, or perform full rewinding of the tape to the point where the full erase head is located at the time of tape recording, and then fast forward to the recording start point again. To erase the image data of the tape section existing between the head and the recording start point. By controlling the driving mode, it automatically drives the technology mechanism during recording without attaching a separate rotary erasing head to erase the old video signal existing between the recording start point and the full erasing head so that it exists in the missing part of the tape. The image quality deterioration of the reproduced video signal due to the old video signal is effectively prevented.

Claims (3)

A transmitter / receiver for transmitting / receiving the control mode of the VRC selected by the user and a key input unit for receiving a key necessary for the operation of the VRC; The deck drive mode is controlled in accordance with the input signals from the receiver and the key input unit, and the deck is quickly moved by the interval between the full width erase head and the recording start point of the tape based on the input signal from the signal reproducing unit in the recording mode. A central control unit for generating a control signal for controlling to be driven continuously in the rewind mode and the fast forward mode; A signal reproducing unit which provides a signal for mode control to the central controller in the recording mode, and reproduces a video signal recorded on a tape in relation to a deck mechanism based on a control signal from the central controller; And a signal processing unit for processing a video signal output from the signal reproducing unit into a displayable signal through a monitor. Operating the full width erasing head during the recording mode operation and automatically rewinding the recording start point of the tape to the portion where the full width erasing head is located to erase the image data existing between the full width erasing head and the recording start point of the tape. And driving the deck in fast forward mode to return the recording start point of the tape to the initial position when erasing of the image data of the target tape section is completed in the erasing step. Automatically rewinding the recording start point of the tape to a portion where the full width erasing head is located during the recording mode operation; When the rewinding of the target tape section is completed in the rewinding step, the full width erasing head is operated and the tech is fast-forwarded to the recording start point of the tape to return the tape to the initial position. Editing control method of V-Cal comprising the step of erasing the image data existing in between. ※ Note: The disclosure is based on the initial application.
