If you try to use the remote control (hereinafter simply referred to as the remote control), since both video tape recorders are from the same manufacturer, the remote control code (hereinafter simply referred to as the remote control) has the same system code.
Since they are designed to operate with the same Formatsu 1- signal), if you operate the remote control f1, both video recorders will be in the same mode, making dubbing easier. There is the inconvenience that the video tape recorder on the machine cannot be operated.

Note that even if the two video tape recorders used during dubbing are not made by the same manufacturer, the same problem will occur if they operate with remote control codes having the same system code.

Therefore, each manufacturer is installing a changeover switch on the remote control to switch and transmit two or more types of remote control codes with different system codes ()A-Matsu1-), and changing the changeover switch of the controller. At the same time, the video tape recorder, which is equipped with a receiving device that receives remote control signals, transmits two or more types of remote control codes with different system codes.
A changeover switch is provided so that it can operate with more than one type of remote control code, and by changing the changeover switch on the receiving device, each video tape recorder can operate with two or more different types of remote control codes. I am trying to make each one work. During dubbing, the changeover switches on both the remote control side and the receiving device side are respectively switched so that the playback side video tape recorder and the recording side video tape recorder operate with different remote control codes.

In other words, the video tape recorder on the playback side is
The system code (format) of
Switch to operate with a remote control code that has a different type of system code (format). - way,
By transmitting a remote control code having a system code (format) of type 11 A II from the remote control, only the video tape recorder on the playback side is operated in the playback mode, and by switching the remote control selector switch, By transmitting a remote control code having a system code (format) of type 11811, only the video tape recorder on the recording side is operated to enter the recording mode.

(Problem to be solved by the invention) However, as mentioned above, if the remote control is equipped with a changeover switch (
), it is unavoidable to perform switching operations as necessary, but installing a switch on the receiving device side is also inconvenient in terms of operation, and the additional switch increases the cost. There are some problems.

Therefore, the present invention solves the above-mentioned problems of the conventional technology, eliminates the need for a changeover switch provided on the receiver side, and further improves the ability to dub two or more video tape recorders using a remote control.

In addition, after decoding the remote control code in step 16, it waits for reception of the next remote control signal, and similarly, if the received system = 1-code is not formatted in step 18.19, the next remote control signal is also Wait for a signal to be received.

Note that in the above-described embodiment, L A 11. Although we have described a device that selects and receives two types of remote control signals (B11), it is also possible to select and receive other types of remote control signals such as II CI+, 11 Dll, etc. In that case, you can expand by preparing programs (software) that correspond to each type of remote control signal in advance, and increasing the number of contacts on the remote control switch and the number of points that switch each program in the receiver. can be done easily.

In addition, in the embodiment described above, the operation starts after the power (AC) is turned on, and the first received remote control signal (remote control code) at that time is stored in the memory according to the type of system code. I re-formatted to store the data, but I also formatted it by turning on the power (AC) and then re-formatting it without turning it on again (not turning it off for 10N). The type of system code may be matched to set the time to the start of the operation. In that case, when the power (AC) is turned on and a certain type of system code has been formatted, for example, in order to send a specific operation button on the receiving device side and the type of remote control signal that you want to format from the remote control. By pressing the operation button on the remote control at the same time, a new type of system code may be formatted without turning on the power (AC).
