Description

Title composition method in video tape recoder

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of editing a title in a video recorder, and more particularly, to setting and modifying / deleting a title in a video recorder having an on-screen display (OSD) chip and a microcomputer to create a title. It is about a method.

In general, the title editing apparatus in the video recorder is shown in FIG. That is, the title editing apparatus includes a keyboard 100, a microcomputer 110, an OSD chip 120, and a video chip 130.

The keyboard 100 transmits a keyboard signal for editing a title to the microcomputer.

The microcomputer 110 performs all algorithms related to title editing according to a signal input from the keyboard 100 and transmits the character code data into a recorder and a non-recorder to the OSD chip 130.

The OSD chip has a character font for the character data transmitted from the microcomputer 110, and receives a horizontal synchronous signal and a vertical synchronous signal synchronized with a video signal to be synthesized, and generates a recorder character signal and a non-recorder character signal. To the video chip 130.

The video chip 130 loads the text signal input from the OSD chip 120 to the video composite signal, records the video recording signal on the video tape 150, and records the video recording signal on the video tape 150 by the monitor 140. To be displayed.

The conventional title editing method used by the microcomputer 110 in the video recorder as described above divides the screen into a keyboard for selecting letters and a title plate for editing titles during the title editing process, By using only the right key, a character in the keyboard can be selected, and the selection cursor can be moved only in the keyboard.

The title editing method of the conventional video recorder as described above has a disadvantage in that the user sets, modifies, and deletes a title, which is somewhat inconvenient and takes much time.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for setting, correcting, and deleting titles in a video recorder that can more easily and conveniently perform title editing operations of a video recorder.
