Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a teletext receiver.

[Outline of device]

The present invention relates to a teletext receiver, a receiver capable of receiving a teletext signal or a television signal, an operating means capable of instructing at least various modes of the teletext signal, and teletext signal data based on an instruction of the operating means. In a teletext receiver composed of a printer for copying, the operation of the copy command key for instructing the copy of the teletext signal data provided in the operating means is performed at least as a double operation, and the copy command key is erroneously operated. The printer is designed to prevent unintentional operation and prevent wasteful use of paper in the printer.

[Conventional technology]

Recently, teletext has been performed in which teletext programs are transmitted by utilizing the time gap of television broadcast waves. This teletext program has various news, weather forecasts, traffic information,
In addition to daily life information such as stock market conditions, various types of information such as subtitled super programs and quiz programs are broadcast by a hybrid system.
Such a character broadcasting signal, that is, pixel pattern data such as characters and figures is converted into a digital signal and a control signal indicating a magazine number, a program number and a page number representing a program group is added to the storage means of a large capacity. To store. Further, a synchronization code, an error correction code, etc. necessary for transmission are added to the stored data, and these character broadcasting signals are superposed on the vertical blanking period of the television signal by the multiplexer (the 14th bit in the first odd field). The second horizontal period (14H), 15th, 16th
H and 21H, and in the next even-numbered field, 277H, 278H, 279H, and 284H are superimposed).
Such a teletext signal is transmitted as a radio wave from the transmitting device.In the teletext receiver, the video signal selected and detected by the television receiving circuit is supplied to the text signal decoder and superimposed on the vertical blanking period. Is separated from the video signal, the desired teletext program is selected by operating means for remote control, the text signal is decoded, and the decoded signal is supplied to the text signal generator to display the text signal on the cathode ray tube. It is designed to do. Details of such a teletext receiver are disclosed in JP-A-59-165582 previously proposed by the applicant of the present application.

[Problems to be solved by the invention]

As the above-mentioned teletext receiver, in order to print and record the screen data of the teletext signal on paper by the operation means for remote control, the text signal decoder is provided with a terminal for connecting a printer, A printer is connected to this printer terminal. Such a printer configuration is disclosed in, for example, Japanese Patent Laid-Open No. 57-61386 proposed by the present applicant.

Since the above-mentioned remote control operation means is small in size and provided with many operation keys, it often happens that the copy command key for operating the printer is unintentionally pressed. The printer receives the copy command,
There is an inconvenience such as wasting copy paper for entering the copy operation.

The present invention has been made to solve the above-mentioned inconvenience, and an object of the present invention is to provide a teletext receiver having a remote control operation means that does not waste print paper.

[Means for solving problems]

The teletext receiver of the present invention, as shown in FIG. 1 by way of example, can indicate a receiver (2) capable of receiving a teletext signal or a television signal and at least various modes of the teletext signal. In a teletext receiver (1) comprising an operating means (17) and a printer (16) for copying teletext signal data based on an instruction from the operating means (17), the teletext signal provided in the operating means The operation of the copy command key (17ax) for instructing the copy of the image data is performed at least in double operation.

[Action]

In the teletext receiver of the present invention, the copy command key (17a) is protected by, for example, a protector, or it is necessary to perform a double operation such as pressing two copy command keys simultaneously. Since the copy operation is not performed, a teletext receiver can be obtained in which the copy command key cannot be operated unintentionally by mistake.

〔Example〕

An embodiment of the teletext receiver of the present invention will be described below with reference to FIGS.

In FIG. 1, a teletext receiver (1) is a television receiver incorporating a teletext decoder, and a normal television signal is caught by an antenna (3).
It is tuned by the tuner (4) and separated by the video intermediate frequency amplifier circuit (5) into a video signal and an audio signal. This video signal is detected by the video detection circuit (6) and the video and audio of teletext and television broadcasts. It is supplied to the video / color signal processing circuit (9) through the video / audio switching circuit (8) for switching the signal, and the cathode line through the RGB switching circuit (10) for switching the red signal R, the green signal G and the blue signal B of the three primary colors. Supply to the tube (11) to display a television screen on the cathode ray tube. The audio signal is emitted from the speaker (15) through the audio detection circuit (7) → the video / audio switching circuit (8). When the television signal contains a teletext signal, the video signal and audio signal obtained by the video detection circuit (6) and the audio detection circuit (7) are sent to the text signal processor (14) including the text signal decoder. The supplied character and graphic signals are decoded from the video signal. Of course, the contents of these teletext programs are selected by the remote control operation means (17), and the selection command data received by the remote control reception section (12) is supplied to the microcomputer (13), and the tuner (4) and the text signal processor are supplied. It is designed to operate (14).

The decoded character signal is converted into an analog R, G, B three-primary color signal and supplied to the R, G, B switching circuit (10),
Characters and graphics are displayed on the cathode ray tube according to control signals from the character signal processor (14). Also, when melody is played according to the display of notes, additional sounds, etc. are similarly decoded by the decoder in the character signal processor (14) and supplied to the video / audio switching circuit (8) for control from the character signal processor (14). The signal is emitted from the speaker (15). When superimposing the teletext screen on the television broadcast screen, the RGB signal from the character signal processor (14) and the RGB signal from the video and color signal processing circuit (9) are combined to produce a cathode ray tube (11). ), The receiver (2) is configured as a whole.

The character signal processor (14) has a printer connection terminal because the screen is often printed and recorded on paper due to the nature of character broadcasting. (16) indicates a printer connected to this terminal, and when printing is performed, a predetermined screen is printed by pressing a copy command key (17ax) provided on the remote control operation means (17). Can be done.

The remote control operating means (17) used in this example will be described in detail with reference to FIGS. 2 and 3. As shown in FIG. 2, the remote control operation means (17) has a plurality of operation key groups (17Z),
