Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an apparatus according to the present invention, where 10 is a schematic block diagram of a remote control for controlling the driving of a VCR.

As shown, the remote controller 10 includes a function key K1 for controlling the operation of the VCR, selection keys K21-K23 for selecting the plurality of VCRs V1-V3, a numeric key K3, and the like. The key matrix 11 is configured, and the microcomputer 12 is configured to search for the pressed keys of these keys K and apply the corresponding key signal to the transmitter 13. At this time, the microcomputer 2 of the present invention adds a predetermined identification signal selected by the selection keys K21-K23 to the key signal and applies it to the transmitter 13. That is, there are three kinds of identification signals (the number of types of identification signals correspond to the number of selection keys K21-K23) in the microcomputer 2, and one of the selection keys K21-K23 is present. If is pressed, the identification signal of the first selected selection keys K21-K23 is added to the key signal and applied to the transmitter 13 until the other selection keys K21-K23 are pressed. It will be readily apparent to one of ordinary skill in the art that such an identification signal should be added to a custom code that is typically transmitted in a VCR.

The transmitter 13 is configured to apply these key signals to the VCRs V1-V3 as infrared signals or the like via light emitting diodes or the like.

In addition, the remote controller 12 of the present invention has a display unit 14 as shown, and the microcomputer 12 is configured to display the information on the pressed key through the display unit 14.

If the VCRs V1-V3 have the same configuration, they are configured to drive corresponding to the key signals of the remote controller 10. However, different identification signals are stored in the microcomputer 21 inside the respective VCRs V1-V3, and received only when the identification signal added to the key signal applied from the remote controller 10 and the stored identification signal are the same. The drive corresponding to the key signal is performed.

That is, the VCR V1 is configured with a receiver 22 as shown, and the receiver 22 is composed of an infrared transistor or the like to receive a signal transmitted from the remote controller 10 and apply it to the microcomputer 21. Consists of. The microcomputer 21 inputs these key signals and first determines whether the input predetermined identification signal is the same as its own identification signal stored in the internal memory. When the identification signals are the same, the driving of the deck 23 and the reproduction processing system 24 is controlled in response to the input key signal.

Here, the deck 23 refers to all mechanical and circuit configurations of the VCR in which the video tape is loaded and the video signal of the loaded video tape can be read and output under the control of the microcomputer 21.

The video signal read out from the deck 23 is applied to the reproduction processing system 24 as shown in the figure, and the reproduction processing system 24 is configured to reproduce the image signal and display it on a monitor or the like.

2 shows a flow chart of the microcomputer 12 in which the remote controller 10 having the above-described configuration performs the present invention.

As shown, the microcomputer 11 determines whether the playback time setting key is pressed among the keys of the key matrix 11 (S1). If the playback time setting key is pressed, the process proceeds to step S2.

In step S2, the microcomputer 11 determines whether one of the above-described selection keys K21-K23 has been pressed, and transmits information on the selected selection keys K21-K23 to a predetermined address N of the internal memory. Save (S3). Then, the microcomputer 12 displays the current time through the display unit 14 in step S4 (S4), and as the numeric keys K3 are pressed (S5), the current time is changed (S6). ). However, when the numeric key K3 is not pressed in step S5, the microcomputer 12 determines whether the playing time setting completion key is pressed (S7), and when the playing time setting completion key is pressed, the display unit is pressed. The current time of (14) is set as the playback start time and stored in the address N (where information on the selection keys K21-K23 is stored) (S8).

Then, the microcomputer 12 changes the current time of the display unit 14 as the numeric key K3 is pressed again (S9, S10), but if the numeric key K3 is not pressed in step S9, It is determined whether or not the reproduction time setting completion key is pressed (S11). When the reproduction time setting completion key is pressed, the current time of the display unit 14 is set as the reproduction start time and stored in the address N (S12). That is, the microcomputer 12 stores the information on the set playback start time and playback end time together with the information on the selected selection keys K21-K23 at the same address, so that the information on this playback start and end time is not changed. It stores the information about (V1-V3).

In addition, it will be readily apparent to those skilled in the art that the microcomputer 12 may store a plurality of pieces of information on the reproduction time.

On the other hand, if the playback time setting key is not pressed as a result of the determination of step S1, the microcomputer 12 proceeds to step S13 to determine whether the current time is one of the set playback start times, and the playback start time. One of these methods reads information on the selection keys K21-K23 stored at the same address as the reproduction start time (S14).

Then, the microcomputer 12 applies the predetermined identification signal and the reproduction key signal corresponding to the read selection keys K21-K23 to the transmitter 14 (S15). Thus, the predetermined VCRs V1-V3 corresponding to the read selection keys K21-K23 will be driven in the playback mode.

After performing step S15), the microcomputer 12 determines whether the current time is the playback end time stored at the same address as the read selection keys K21-K23 (S16). The predetermined identification signal and the stop key signal corresponding to the selected selection keys K21-K23 are applied to the transmitter 14 (S17). Therefore, the VCR (V1-V3; corresponding to the selection keys K21-K23) that were driving in the regeneration mode will be converted to the stop mode.

In the above-described embodiment, the remote controller 10 transmits a reproduction key signal, a stop key signal, and a predetermined identification signal. However, if necessary, the remote controller 10 may add and transmit a power on and power off key signal. Those skilled in the art will readily know.

As can be seen from the above description, the playback time of the VCRs V1-V3 can be controlled using the remote controller 10 and the VCRs V1-V3 of the present invention. It can be seen that video tapes loaded on the cards can be sequentially played.

As described above, the present invention can control the playback time of a plurality of VCRs using a single remote controller, so that video tapes stored in the plurality of VCRs can be played and viewed sequentially at a desired time.
