Abstract

PURPOSE:To offer an economical and very convenient printer by utilizing a remote control function of a television receiver so as to execute print-out of a television signal. CONSTITUTION:An A/D converter 1 uses a clock pulse (p) of a clock pulse generating circuit 7, samples a video signal (v) and outputs a gradation density signal d1. When a viewer operates a copy key 6 or a copy function key of a remote control transmitter 9, a CPU4 generates a write command c2 of a write control circuit 3 and the gradation density signal d1 is written in a video image memory 2 in the timing of the said clock pulse (p).

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a printer device for television signals.

[Prior art]

Generally, when a cooking program is being broadcast on a television receiver, you may want to write down the menu list and ingredients displayed on the screen. This was extremely inconvenient as the person had to take notes on the menu list, ingredients, etc. while looking at the screen each time. In addition, if the cooking program mentioned above is recorded on a VTR, it can be played back again, but even in that case, it is necessary to search for the necessary screen and perform operations such as static playback, which is complicated. Ta.

Therefore, the inventor proposed that the gradation signal of the image on the television screen be R.
We have already developed a printer device for a television receiver that can automatically make a hard copy of television screen images by writing to AM and then reading it.

It would be very convenient for viewers if copy commands could be sent using a remote control in such television signal printers.

[Summary of the invention]

An object of the present invention is to provide a television signal printer in which a copy command can be transmitted using a remote control.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is an A/D converter that A/D converts a video signal V and outputs, for example, a 4-bit gradation density signal d1; 2 is a video memory that stores the gradation density signal dl;
3 digit writing finger -f? A write control circuit that controls writing to the video memory 2 according to c2; 4 is a copy key 6;
Alternatively, a write command c2 is given to the write control circuit 3 in response to copy commands cl and c3 from the outside, and a bladder ejecting address a is outputted to the video memory 2, and the bladder ejecting data d2 from the video memory 2 is used as print data d3. CPU to output.

5 is a printer that prints the read print data d3. Note that 7 is a clock pulse generation circuit that supplies clock pulses p to the A/D converter 1 and the write control circuit 3, and 11 and 11 are horizontal and vertical synchronizing signals, respectively, which are connected together with the video signal V via a connector or the like. television receiver 8 or VTR
etc. is input. In addition to the copy function key, 9 is a remote control transmitter equipped with various function keys for TV control such as channel selection, volume adjustment, etc.
is a remote control decoder, which is built in the television receiver 8, decodes the transmission signal from the remote control transmitter 9, sends a copy command 03 to the CPU 4, and sends TV control commands 04 such as volume and channel selection to the television receiver. The direction toward the main body is for output.

Next, the operation will be explained. The A/D converter 1 samples the video signal V using the tally clock pulse p from the tally pulse generating circuit 7, and outputs a gradation density signal d1. The write control circuit 3 writes the gradation density signal dl into the video memory 2 at the timing of the clock pulse p according to the write command 02. Using this convolution control circuit 3/i horizontal and vertical synchronizing signals 81 and 82,
Control is performed so that the gradation density signal for 0 pixel and 234 lines in the vertical direction is written to the correct address in the video memory 2. The write command 02 of the write control circuit 3 is issued from the CPU 4 when the viewer operates the copy key 6 or the copy function key of the remote control transmitter 9.

When the writing to the video memory 2 is completed, the CPU 4 gives the read address a to the video memory 2, and reads out the gradation density signal d2 from the memory 2. This gradation density signal d2 is output as print data d3 to the printer 5, which prints it, resulting in a copy of the television screen.

〔Effect of the invention〕

As described above, according to the present invention, television signals can be printed out by using the remote control function of a television receiver, and an economical and very convenient printer device can be provided. be.
