Description

Low Power TVR

The present invention relates to a device for reducing power consumption of a complex electronic product, more specifically, a low-power TVCR device that reduces power consumption by cutting off the power supply to the remaining component blocks except for the function that the user wants to use It is about.

In accordance with the recent multimedia trend, a composite electronic product having a plurality of functions has emerged. For example, TVCR devices in which a TV system and a VCR are generally used in each home are widely used. The TVCR device improves the inconvenience of connecting input / output signal lines, redundant functions of internal circuits, and dual control circuits by using TVs and VCRs separately. By producing devices by combining each function, there are many advantages such as not only unifying the redundant portions of a signal processing circuit as one, but also internally processing signal lines to be connected externally.

However, when operating the conventional TVCR device as described above, although a plurality of functions included in the complex system may be used at the same time, each function is often operated separately. At this time, although there is a configuration block that does not operate, power is supplied to the entire configuration, causing unnecessary power consumption.

Accordingly, an object of the present invention is to provide a microcomputer and a switch device, so that the user inputs the functions required by the user, so that the power is supplied only to the component blocks necessary for the performance of the functions, and other configuration blocks. It is to provide a low power consumption TVCR device that can reduce the power consumption by cutting off the power supplied to.

The low-power consumption TVCR device of the present invention for achieving the above object, the input unit for adjusting the channel selection and a plurality of functions, the control information signal for controlling each component of the TVCR device according to the channel and the function selected from the input unit A switching switch unit for selectively driving the respective components of the TVCR device by applying power according to the control information signal input from the microcomputer unit and the microcomputer unit, and controlling the application of operating power from the switching switch, and according to the control signal of the microcomputer unit. A channel separation unit for selecting a channel, a tuner unit for tuning a transmission signal of a channel selected by the channel separation unit, a signal processing unit for receiving a signal transmitted from the transmission signal of the channel selected by the tuner unit and a signal read from the tape deck unit, and a switching switch unit. Is controlled by the application of the operating power source and recorded on a tape inserted under the control of the microcomputer unit. A tape deck for reproducing a signal, and a CRT for receiving various signals from the signal processor and a speaker for outputting a variety of images.

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

1 is a block diagram of a low power consumption TVCR device according to the present invention, and includes a plurality of tuners for TV viewing and recording.

The user selects a channel in the input unit 10 and adjusts various functions of the TVCR device. That is, if a user selects whether to watch TV broadcast or drive a VCR to perform recording or video viewing, information related to the function selection is moved to the microcomputer unit 20. You can also enter a program for reservation recording. The microcomputer 20 determines which part of each component of the TVCR device is to be operated according to the function or program selected by the input unit 10, generates a control information signal necessary for control, and sends it to the switching switch unit 30. Output In addition, the microcomputer 20 applies a partial control information signal to the channel separator 40 and the tape deck 70. The switching switch unit 30 opens and closes the driving power applied to each component of the TVCR device in accordance with the control information signal received from the microcomputer unit 20.

The input signal of the channel selected by the channel separator 40 is applied to the tuner unit 50 according to the intention of the user. The channel separator 40 separates the broadcast signal of the selected channel among the broadcast signals input through the antenna and transmits the broadcast signal to the tuner 50. The tuner unit 50 is composed of a first tuner 501 and a second tuner 502. Multiple or multiple tuners are required for watching many channels of broadcast and for simultaneous recording of multiple channels.

The tape deck unit 70 inserts a video tape to read and record video signals recorded on the video tape. If the user selects video viewing, the tape deck unit 70 is driven and the tape deck unit ( The signal read from the head of 70 is applied to the signal processor 60.

The signal processor 60 receives a signal from the tuner unit 50 and processes the input signal to output an image signal and an audio signal. The video signal processed by the signal processor 60 is applied to the CRT 80 and manifested, and the audio signal is output from the speaker 90.

The switching switch unit 30 includes a plurality of switches, by using the switch, the channel separating unit 40, the first and second tuners 501 and 502, the tape deck unit 70, the CRT 80 and the speaker ( 90) control the opening and closing of the driving power applied to each component. When the user selects the TV viewing, the switching switch unit 30 under the control of the microcomputer unit 20 does not need to operate for watching TV, the tape deck unit 70 and the second tuner 502, etc. Except for TV, power is applied to the remaining components required for watching TV. When the scheduled recording is performed by the program, the signals processed through the channel separator 40, the first tuner 501, and the signal processor 60 are recorded on the video tape inserted into the tape deck 70. By shutting off the power to the second tuner 502, the CRT 80, the speaker 90, etc., which do not need to operate, unnecessary power consumption is suppressed to reduce power consumption.

As described above, according to the present invention, the low power consumption TVCR device has a microcomputer unit and a switching switch unit and applies power only to a component that performs a desired function, thereby reducing unnecessary power consumption.
