Abstract

PURPOSE:To transmit a copy command under remote control by adding a remote control function to a printer device which prints out the image of a TV receiver. CONSTITUTION:An A/D converter 1 samples a video signal (v) by using pulses (p) of a clock pulse generating circuit 7 and outputs a gradational density signal d1. A write control circuit 3 writes the signal d1 in a video memory 2 at the timing of the pulses (p) under a write command c2. The circuit 3 uses horizontal and vertical synchronizing signals s1 and s2 for such control that the gradational density signal of horizontal 280 picture elements and vertical 234 lines is written in correct addresses of the memory 2. The write command c2 of the circuit 3 is generated by a CPU4 when a copy key 6 or the copy function key of a remote control transmitter 8 is operated. The CPU4 supplies a readout address to the memory 2, which outputs a gradational density signal d2 to print out print data d3 on a printer 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printer device for a television receiver.

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 play it back statically, which is a cumbersome operation. .

Therefore, the inventor of the present invention has determined that the gradation density signal of the image on the television screen is 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.

By the way, in such a printer device of a television receiver, it would be very convenient for viewers if a copy command could be sent using a remote control.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a printer device for a television receiver as described above, in which a copy command can be transmitted using a remote control.

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

The drawing shows a printer device for a television receiver according to an embodiment of the present invention, and in the drawing, numeral 1 denotes an A/D that converts a video signal V into a digital signal and outputs, for example, a 4-bit gradation density signal d1. Converter; 2 is a video memory that stores the gradation density signal d1; 3 is a write control circuit that controls writing to the video memory 2 in accordance with a write command c2; 4 is a copy key 6 or a copy command from an external source; A write command c2 is given to the write control circuit 3 according to the signals cl and c3, and a read address a is output to the video memory 2.
A CPU 5 outputs the read data d2 as print data d3, and a printer 5 prints out the read print data d3. Note that 7 is the A/D converter 1 mentioned above.
and a clock pulse generation circuit that supplies clock pulses p to the write control circuit 3; sl and s2 are horizontal and vertical synchronizing signals, respectively. In addition, 8 is a remote control transmitter equipped with various function keys for TV control such as channel selection, volume adjustment, etc. in addition to the copy function key;
is a remote control decoder, which decodes the transmission signal from the remote control transmitter 8 and sends the copy command c3 as CP, tJ.
4, television control commands c4 such as volume, channel selection, etc. are output to the television receiver body.

Next, the operation will be explained. The A/D converter 1 samples the video signal V using the clock pulse p of the clock pulse generation circuit 7, and outputs a gradation density signal d1. The write control circuit 3 writes the gradation density signal d1 into the video memory 2 at the timing of the clock pulse p according to the write command c2. This write control circuit 3 uses horizontal and vertical synchronization signals s1 and s2 to write 280 pixels in the horizontal direction.
Control is performed so that gradation density signals for 234 lines in the pixel plane direction are written to correct addresses in the video memory 2. The write command C2 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 8.

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 out, resulting in a copy of the television screen.

As described above, according to the present invention, since a remote control function is added to a printer device that can print out images from a television receiver, it is possible to provide a printer device that is very convenient for viewers.
