Computer-TV video converting apparatus
First Claim
1. A computer-TV, video converting apparatus which converting any determined partial area of a computer display to a zoomed image displayed on a TV, screen by operating a computer mouse or a mouse functional remote controller to move the computer cursor to a center of the partial area which expect to convert, in addition to a preformed partial area converting function which comprises:
- a computer cursor coordinate converting device attached to the computer for converting an absolute coordinate of the cursor center into a relative coordinate and setting a frame of the partial area of said computer display expected to zoom;
a main converter for converting partial area of computer display signal into a zoomed display video signal to the TV, screen mainly comprising an analog/digital (A/D)) converter, a clock/timing generator, a flick filter for temporarily storage the data provided from said A/D converter and said clock/timing generator, a microprocessor for receiving the relative coordinate data came from said computer cursor coordinate converting device and delivering the processed data to a display controller according to the timing data produced by said clock/timing generator, a display clock/timing generator and said clock/timing generator for controlling a zoom rate signal and area size signal and delivering those to a video encoder through a TV, synchronous signal generator and a digital/analog (D/A) converter for providing the acceptable video signal to the TV, screen, and a remote signal receiver for receiving the remote signal for said microprocessor; and
a remote controller providing infrared or radio signal to said remote signal receiver of said main converter comprising a mouse functional knob for moving the cursor, two mouse functional button, including a selector and a clear button and a plurality of functional keys including at let a zoom function key, a zoom rate control key and a group of partial area performance keys each preset to convert a preformed partial area of said computer display respectively into said zoomed image displayed onto the TV, screen.

Abstract
A computer-TV, video converting apparatus which transfers any determined partial area of a computer display into a zoomed image displayed onto a large scale TV, screen used for a briefing or a seminar in addition to a preformed partial area converting function, comprising a main converter with a build-in remote signal receiver, a computer cursor coordinate convening device and a remote controller while the remote controller provides the infrared or radio signal to the remote signal receiver by operating the mouse function keys of the remote controller to move the cursor to a center of a determined partial area of the computer display. The computer cursor coordinate converting device converts the absolute coordinate of the cursor center into a relative coordinates and sent the relative coordinate data to the main converter, a microprocessor and a display controller of the main converter then converts the expected zoom area into a video signal to the TV, screen to provide a zoomed image thereon.
