JPS61182381A - Two-pattern television receiver - Google Patents

Abstract

PURPOSE:To print the information of a slave pattern as a hard copy by converting a digital signal read from a memory for displaying the slave pattern from a parallel data into a serial data and applying the data to an external printer. CONSTITUTION:A parallel digital signal for displaying the slave pattern read from the memory 5 is processed by an input signal processing section 8, stored temporarily in a memory section 10 via a data control section 9, read out of the section 10 and converted into a serial signal by a parallel/serial data converting section 11 and outputted to a printer 14 connected externally via a data transmission section 12 and a printer control section 13. Thus, the slave pattern is printed by the printer 14 as a hard copy.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a two-screen television receiver that simultaneously displays another image (child screen>1) on a part of the television screen.

BACKGROUND OF THE INVENTION With the development of new media equipment, two-screen color television sets have been introduced. For example, in the April 14, 1980 issue of Nikkei Electronics, a ``two-screen television using digital memory and dedicated control IIX'' was announced.

In this type of two-screen television receiver, for example, the second
As shown in the figure, one τ, R-! for small screen display that has been subjected to video chroma processing. , B-Y signal is converted into a digital signal by the MU/D converter 1 and stored in the memory 2 for displaying a small screen, and a part of each 6 bits of the digital signal is read from the memory 2.

After the R-Y and B-Y signals are converted into analog signals by the D/MU converter 3, they are outputted as RGB signals by the RGB synthesis circuit 4, and supplied to the cathode ray tube for display.

Problems to be Solved by the Invention However, in such a two-screen television receiver,
In the process of signal processing, a digital signal is generated and written to the memory 2 for future reading.
Image processing using digital technology allows the sub-screen to remain still, but there is a problem in that no other image processing is performed. Therefore, the present invention makes it possible to print images on an externally connected printer using a certain sub-screen display signal, thereby making more effective use of digital signals.

Means for Solving the Problems In the two-screen television receiver of the present invention, a digital signal of parallel data read from a memory for displaying a sub-screen is converted into serial data, and the serial data is supplied to an externally connected printer. This made printing possible.

According to the two-screen television of the present invention, printing is made possible by signal processing the signal for displaying the sub-screen read from the memory and supplying the signal to an externally connected printer. It is possible to obtain a hard copy of the TV receiver and introduce new additional functions to the TV receiver.

Embodiment Hereinafter, a two-screen television receiver according to an embodiment of the present invention will be explained with reference to the drawings.

As shown in FIG. 1, the digital signals of the Y, R-Y, and B-Y signals read out from the memory 5 for displaying the small screen are as follows.
The D/A converter 6 converts the signal into an analog signal as a small screen display signal, and outputs the signal to the cathode ray tube via the RGB synthesizer 7.

On the other hand, in the present invention, the input signal processing section 8 processes the parallel digital signals for child screen display read out from the memory 5, and temporarily stores them in the memory section 1o via the data control section 9. , which is then read out, converted into a serial signal by the parallel-serial data converter 11, and outputted to the externally connected printer 14 via the data transmitter 12 and printer controller 13f.

This allows the printer 14 to print the child screen as a hard copy.

Effects of the Invention As described above, according to the present invention, by converting the digital signal read from the memory for displaying the sub-screen from parallel data to serial data and supplying it to an external printer, the information on the sub-screen can be... It is extremely useful in practical terms because it can be printed as a tocobee and can introduce new additional functions to television receivers.
