Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides video
The present invention relates to a control signal communication system suitable for use in remotely controlling equipment such as a TR, and equipment and peripheral equipment using the same.

[Summary of the invention]

The present invention relates to a control signal communication method and equipment and peripheral devices using the same, and by determining the corresponding mode from the command key operation and transmitting a signal according to this mode, it is possible to easily connect models with different command key operations. This allows remote control to be performed.

[Conventional technology]

For example, when recording is performed using a VTR separate from a video camera, it is extremely convenient to be able to control the VTR from the camera side. In addition, VTRs are controlled from an editing device, a timer unit, a remote control command device, or the like.

In such control, conventionally, a peripheral device such as a video camera is provided with command keys similar to those of the VTR itself, and signals from these command keys are converted to a communication former 7) and transmitted, and the VTR On the side, these signals are replaced with signals from the built-in command keys for control.

[Problem to be solved by the invention]

However, the control using the command keys described above is performed using the key ff1.
There is no uniformity among manufacturers regarding the correspondence between the production and the actual operating mode of the VTR. For example, high-speed playback is generally performed by operating the fast forward 7 rewind keys in playback mode, but some manufacturers High-speed playback is performed only when the key is pressed, whereas other manufacturers allow high-speed playback to continue with a temporary key operation, and returning from this high-speed playback is also possible by operating the fast forward 7 rewind keys again or playing. There are various ways to operate keys. Also, still image playback is normally performed by operating the pause key in playback mode, but from now on, recovery will be diverse, such as re-operating the pause key or operating the playback key.

For this reason, in the past, it was not possible to connect or remotely control devices between manufacturers with different Macondo keys.

In response to this, the applicant has previously proposed a method for converting the transmitted command key operation signal to be equivalent to the built-in command key operation by providing means for converting the key operation signal (particularly (See Application No. 159931/1983). However, although this method is effective between two models, it is difficult to achieve greater versatility because the contents of the conversion become complicated.

In addition, with keys that are controlled only while being pressed, such as the above-mentioned pause key and power key, which have a so-called toggle operation, or the above-mentioned fast forward 7 rewind keys, it is not possible to perform good control only by converting the signal. It was something.

This application was filed in view of these points.

This is a peripheral device that uses the control signal communication method of the first means, which determines the mode (33) based on the determined mode, and transmits (34) a signal according to the determined mode.

[Means to solve the problem]

A first means for solving the problems in the present invention is to control a device (2) in which a desired mode of control is executed by a predetermined command key operation. This is a control signal communication system in which the mode is determined and a signal corresponding to the determined mode is transmitted (3) to control the device.

The second means is that when the signal is from the built-in command key (11), this signal is converted into a mode signal (17) and supplied to the mode control means (19), and when the signal is from the communication, this signal is converted to a mode signal (17). Supplied as it is to the mode control means (18
) This is a device using the control signal communication method of the first means described above.

130) The means is one arbitrary command key (31)
[Effect] According to this, since signals are transmitted according to the mode, it becomes easy to deal with the devices and peripheral devices, and it is easy to connect and remotely control devices that require different command key operations. can.

〔Example〕

In Figure 1, peripheral equipment (1) such as a video camera and V
There is a path line (3) between the TR and other controlled equipment (2).
) are connected. A mode is determined from a command key operation in the peripheral device [3], for example, and a signal corresponding to the mode is transmitted to the pass line (3).

In other words, for example, if high-speed playback is to be performed while the fast-forward 7 rewind key is being pressed during playback mode, conventionally, a signal intended for the fast-forward 7 rewind key is transmitted. In contrast, with this method, the fast forward or rewind mode signal is transmitted the first time the fast forward or rewind key is pressed, and the normal play mode signal is transmitted when the key is released. transmitted.

Therefore, according to this method, even in devices where high-speed playback is activated by a single key operation and resumed by another key operation, each key operation corresponds to high-speed playback mode and normal playback mode. By transmitting the signal, the signal format can be exactly the same as in the above case.

Alternatively, when returning from a playback/recording pause, for example, even when the pause key is operated again, a signal corresponding to the playback/recording mode is transmitted, so that even if the command key is operated differently, the transmitted signal is formants can be made equal. In this way, communication of the iH control signal is performed.

Therefore, Figure 2 shows the equipment (
An example of 2) is shown below. In the diagram, the device's built-in command key (
The signal from the main body key (11) is sent to the key input circuit (12
), and the signal from the remote control signal receiving section (13) is supplied to the signal control circuit (14) to form a signal corresponding to each command key operation. These signals are supplied to a command key processing circuit (16) through a mixer (15), and the processed signals are supplied to a mode determining circuit (17). In this circuit (17), for example, when a signal is supplied from the fast forward 7 rewind keys during playback mode, a desired mode to be executed in response to a predetermined key operation, such as high speed playback, is determined. . A signal corresponding to this mode is supplied to a mode transition determining circuit (19) through a switch (18), which determines a transition means for transitioning from the current mode to a desired mode, and operates the operating section (20) according to this means. controlled.

Then, for such equipment (2), pass line (3
) The signal from the signal discrimination circuit (21) and the switch (18
) is supplied as is to the mode transition determination circuit (19).

That is, according to the above-mentioned control signal communication method, since a signal corresponding to the desired mode is transmitted to the path line (3), this signal is directly supplied to the circuit (19) to determine the mode transition means. can do.

In this case, in conventional equipment, the signal from the pass line (3), which transmits the signal corresponding to the key operation, is supplied to the mixer (15), for example, as shown in Fig. 3. It can be implemented extremely easily by simply changing the mode transition determination circuit (19).

Further, FIG. 4 shows an example of a peripheral device (1) using the above-mentioned control signal communication method. In the figure, the key input circuit (31)
The signal is supplied to a mode conversion circuit (33) through a command processing circuit (32) and converted into a signal corresponding to a desired mode for a predetermined key operation. The signal in this mode is supplied to the conversion circuit (34) to the communication former 7) and is converted into a signal tailored to the characteristics of the path line (3) (
modulation) and this converted signal is supplied to the pass line (3).

Therefore, in peripheral devices, conventionally the signal from the command processing circuit (32) was directly supplied to the format conversion circuit (34) as shown in FIG. 5A, but in the meantime, the mode conversion circuit (33) It will be inserted,
Here, this conversion circuit (33) is exactly the same as the mode determination circuit (17) in the device (2), and can be implemented extremely easily by reusing this circuit (17).

In addition, in conventional timer units, etc., as shown in the same figure, a signal generated in a desired mode (generating section (35)) is converted into a signal according to a command (circuit (36)).
However, when using the above-mentioned communication method, such a conversion circuit (36) is removed, and the signal from the mode generator (35) can be directly format-converted and transmitted. It is something.

In this way, according to the above-mentioned control signal communication method, since signals are transmitted according to the mode, it is easy to deal with devices and peripheral devices, and it is easy to connect and remotely control devices that require different command key operations. can be done.

Note that this method can also be applied to DATs, cassette tape recorders, etc.

〔Effect of the invention〕

According to this invention, since signals are transmitted according to the mode, it is easy to handle the devices and peripherals, and it is easy to connect and remotely control models with different command key operations. It became so.
