Abstract

PURPOSE:To record date and time during hard copying of television picture plane is executed by providing a date and time setting circuit in the printer of a television receiver. CONSTITUTION:When gradation density signal d1 of a video signal (v) is written in an image memory 2, a CPU4 gives reading address (a) to the image memory 2 and reads out a gradation density signal d2. On the other hand, a date, time setting circuit 8 measures date and time and outputs date and time information d4 to the CPU4. The CPU4 synthesizes date and time information at the time of copy key operation with read out gradation density signal d2 and outputs as printing data d3, and a printer 5 prints out accordingly. Consequently, a hard copy of television picture having date, time etc. when printed out printed in the margin as printer 5 output is obtained.

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 very inconvenient as the person had to look at the screen and take notes on the dedication list and materials each time. In addition, if you record the above cooking program on a VTR and put it there, you can play it again.''However, even in that case, it is necessary to search for the necessary screen and play it back statically, which is complicated. there were.

Therefore, the present inventor has developed a television receiver that can automatically make a hard copy of the image on the television screen by writing the density signal of the image on the television screen into a RAM and then reading it out. It is already being developed.

By the way, it would be very convenient for viewers if such a printer device for a television receiver could add information such as the date 9 hours to the hard copy of the television screen.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a printer device for a television receiver as described above, which is equipped with a 2-hour date setting circuit and adds 2 hours of the date at the time of printing to the screen. There is.

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 response to a write command c2; 4 is a write control circuit that controls writing to the video memory 2 in accordance with a write command c2; Accordingly, a write command C2 is given to the write control circuit 3, which outputs a continuous address a to the video memory 2.The read data d2 from the video memory 2 is combined with date 1 hour information d4, which will be described later, and output as print data d3. The CPU 5 is a printer that prints out 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, sl, s.
2 are horizontal and vertical synchronization signals, respectively. In addition, 8 clocks the date 1 hour and sends the date 2 hour information d4 to the CPU 4.
This is a date and hour setting circuit that outputs .

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 in accordance with the write command C2. This write control circuit 3 uses horizontal and vertical synchronization signals S1 and s2 to
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 νF write command C2 of the write control circuit 3 is issued from the CPU 4 when the viewer operates the copy key 6.

When the writing to the video memory 2 is completed, the CPU 4
gives the read address a to the video memory 2, but does not read out the gradation density signal d2. By the way, it comes with E1.

The time setting circuit 8 measures 1 hour of the date and outputs date 1 hour information d4 to the CPU 4, and the CPU 4 receives the date and time information when the copy key is operated, and receives the read gradation density signal d.
2 and outputs it as print data d3, and outputs it as print data d3 to the printer 5.
will print out according to this. As a result, the printer 5 outputs the hard copy on the television screen with the date, hour, etc. printed on the outside of the hard copy, ie, above or below it, for example. Also, this date, 5 hours, etc. should not be written outside the hard copy margin on the TV screen (
, In the column, for example, make part of the corner of the TV screen white or black, and write the date here in black or white.

The time may also be printed.

In the above embodiment, only the date and 2 hours are recorded, but any information such as the name of the operator may be recorded.

As described above, according to the present invention, it is possible to record 3 hours of the date at the time of recording in a hard copy of a television screen, which is very convenient for use.

Claims (1)

[Claims] (1) A printer device that prints out a video signal from a television receiver, which includes a video memory that stores the gradation density signal of the video to be printed out, and a video memory that stores the gradation density signal of the video to be printed out, and a printer that stores the gradation density signal of the video to be printed out, and that stores data in the video memory in response to a command from a copy key. Write control circuit that performs write control and date. The gradation density signal in the video memory is read out in response to commands from the date 1 hour setting circuit that measures time and the copy key, and the date 2 hour information from the date 1 hour setting circuit is combined with this signal. 1. A printer device for a television receiver, comprising: a readout control circuit that outputs the output to a printer, which will be described later; and a printer that prints out the output of the readout control circuit.
