KR940023201A - Apparatus and method for capturing screen real-time in picture-in-picture television system - Google Patents

Abstract

The present invention is to make the current main picture as the still picture of the PIP when capturing the moment of the screen while watching the main picture. An input unit formed of; An IF processor for processing a signal input through the tuner and outputting the voice signal; A PIP processor connected to the PIP switch to perform the PIP; An image output unit configured to display a signal output through a chroma unit processing a color signal through a color cathode ray tube; An instant capture dedicated PIP processing unit that processes the PIP exclusively; It consists of a switch that can switch between general PIP and instant capture dedicated PIP, and determines whether there is an instant capture key input, and the instant capture key PIP processing unit is “PIP ON” by the microcomputer as the instant capture key is input. Outputting the data as much as possible, determining whether the instantaneous capturing key is turned on as the instantaneous capturing key is not input, and canceling the still release data by the instant capturing dedicated PIP processing unit as the capturing moment is turned on. Outputting “H” at the micom output terminal, and outputting still data to the PIP processing unit dedicated to capturing as the instant capturing is “off”, and outputting “L” at the microcom output terminal. Screen real-time capture device of a picture-in-picture television system and a method thereof.

Claims (3)

An input unit including a microcomputer for tuning and outputting an external input signal selection and tuning through a tuner and key metrics to the tuner; An IF processor for processing a signal input through the tuner and outputting the voice signal; A PIP processor connected to the PIP switch to perform the PIP; An image output unit configured to display a signal output through a chroma unit processing a color signal through a color cathode ray tube; An instant capture dedicated PIP processing unit that processes the PIP exclusively; Picture-in-picture television system capture device, comprising a switch to switch between regular PIP and dedicated PIP. The picture capturing apparatus of a picture-in-picture television system according to claim 1, wherein the instant capturing dedicated PIP processing section and the changeover switch can be replaced with a PIP switching data memory section formed by RAM. Judging whether there is an instant capture key input; outputting data such that the instantaneous capture dedicated PIP processing unit PIP is “on” as the instant capture key is input; Determining whether the capture is "on" or not, and as soon as the instant capture is "on", releasing still release data to the instant capture exclusive PIP processing unit and outputting "H" at the microcomputer output terminal, and the instant capture is "off". And outputting still data to an instant capture dedicated PIP processing unit, and outputting “L” at the microcomputer output terminal. ※ Note: The disclosure is based on the initial application.
