In an image processing system with an on-screen display function, a method of storing data of a row buffer in the on-screen display is to provide to minimize the capacity of the buffer by storing both character data and color data into a signal row buffer, thereby displaying a great deal of information on a monitor. Also, a row buffer control circuit for simultaneously storing characters and color data in the row buffer comprises a control data storing circuit, a column controlling part, a row controlling part, and a signal processing part.

Data storing method of a row buffer in on-screen display and control

A fine adjustment tuning apparatus for televisions includes a key matrix part, a microcomputer part, a local osicillating part, and a red/green/blue mixer part. The method of storing the tuning data includes an initial mode setting step, an on screen display displaying step, a storing deciding step, an input time detecting step, and a key input routine implementing step. The present invention eliminates the need to fine tune each time a new channel is selected.
