Description

Combination system for controlling independently providing power about internal each devices

The present invention relates to a combination system that connects two or more different devices into one system, and a power control method using the same. More particularly, the present invention relates to a VCR and DVDP microcomputer through a VCR microcomputer by connecting a DVDP and a VCR to a single system. The present invention relates to a power controllable DVDP / VCR combination system that performs power control and operation control, and a power control method using the same.

Two or more different devices connected to one integrated system are called a "combination system" or a "combo-system", which is abbreviated as "combo". An example of a combo system is a DVDP / VCR combo system developed to perform a combination of a digital video or versatile disk player (DVDP) and a video cassette recorder (VCR).

FIG. 1 is a diagram schematically illustrating such a DVDP / VCR combo system and peripheral devices connected thereto. The DVDP / VCR combo system 10 includes a VCR unit 11 which performs a function of a general VCR such as a function of reproducing video and audio data recorded on magnetic tape and a function of recording an externally received signal on magnetic tape. And a DVDP unit 12 which performs a function of a general DVDP such as a function of reproducing video and sound data recorded on a digital video disk (DVD). In addition to the independent functions of the VCR unit 11 and the DVDP unit 12, the DVDP / VCR combo system 10 records the images and sounds reproduced by the DVDP unit 12 on the magnetic tape in the VCR unit 11; It has the advantage of being able to perform the same complex function.

The VCR unit 11 and the DVDP unit 12 in the DVDP / VCR combo system 10 are externally present as one system, and the user may use a separate input device such as a remote controller 15 or a DVDP / VCR combo system ( By operating an operation panel (not shown) and the like provided on the front surface of the device 10, mode switching between the VCR unit 11 and the DVDP unit 12 and individual functions of the devices 11 and 12 can be operated.

The TVP 23 may be connected to the DVDP / VCR combo system 10 as a peripheral device for outputting video and sound reproduced by the DVDP unit 12 or the VCR unit 11 therein. In addition, an audio amplifier 21 is connected as a peripheral device for outputting the sound reproduced by the DVDP unit 12 of the DVDP / VCR combo system 10. In addition, an external device 25 such as a camcorder may be connected to the DVDP / VCR combo system 10. The DVDP / VCR combo system 10 receives a video signal and an audio signal from the external device 25 and records them on a magnetic tape inserted into the VCR unit 11 or outputs them to an image output device such as a TV 23. Do this.

On the other hand, the conventional DVDP / VCR combo system 10 is provided with a power switch 13 for supplying power to the VCR unit 11 and the DVDP unit 12 from the power supply terminal 20. Therefore, when power is applied to the DVDP / VCR combo system 10 together with power on of the power switch 13, power is simultaneously applied to the VCR unit 11 and the DVDP unit 12. Therefore, there is a problem in that unnecessary power is generated because power is applied to both the DVDP unit 11 and the VCR unit 12 regardless of the operation.

In the DVDP / VCR combo system 10, a microcomputer (not shown) for controlling each operation is provided in the VCR unit 11 and the DVDP unit 12, respectively. At this time, the VCR microcomputer (not shown) installed in the VCR unit 11 controls the operation of the VCR unit 11 and the DVD microcomputer (not shown) of the DVDP unit 12. On the other hand, when power is applied to the VCR unit 11 and the DVDP unit 12 from the power switch 13, the VCR microcom and DVD microcom respectively reset the operations of the VCR unit 11 and the DVDP unit 12 ( reset) operation. At this time, the reset operation of the DVD microcom is performed by the control signal of the VCR microcom. Therefore, before the VCR microcomputer controls the reset operation of the DVD microcomputer, power may be applied to the DVD microcomputer to generate a malfunction signal of the DVD microcomputer. In addition, if any control signal is input from the VCR microcom before the reset operation, the DVD microcom which is not ready to receive the control signal may misinterpret the input signal, thereby causing a malfunction of the DVD microcom. There is a problem that the DVDP unit 12 may malfunction due to a malfunction signal generated. As an example of such a malfunction, a phenomenon may occur in which the disc cartridge of the DVD deck for driving the DVD is drawn out when the initial power is supplied to the dvdp unit 12.

In order to solve this problem, it is necessary to take measures such as supplying power to the VCR unit 11 in time and inserting a time delay circuit for supplying power to the DVDP unit 12 after the DVD micom reset operation is performed. However, this has a problem in that the circuit configuration becomes complicated and the unit price of the product increases.

According to the present invention for solving the above problems, when power is applied to the DVDP / VCR combo system, power consumption is applied to both the DVDP unit and the VCR unit regardless of the device related to the operation of the DVDP unit and the VCR unit. An object of the present invention is to provide a DVDP / VCR combo system and a power control method using the same. In addition, when the power is supplied to the DVDP / VCR combo system, it is possible to prevent malfunctions such as DVD ejection of the DVD deck due to the operation of the DVD micom before the VCR microcom in the VCR controls the reset operation of the DVD micom in the DVDP. Another purpose is to provide a DVDP / VCR combo system and a power control method using the same.
