How to reserve time and channel for video cassette recorder

The present invention relates to a video cassette recorder (VCR), and more particularly, to a video cassette recorder time and channel reservation method for receiving a terrestrial broadcast with a video cassette recorder so that a reserved channel is automatically turned on at a reserved time. will be.

A video cassette recorder is a device for displaying or recording a video or audio signal recorded on a video tape through a television receiver, a monitor, or a separate display means. As a medium for recording video and audio signals on a video tape, a video camera such as a camcorder is used.

Conventionally, an image apparatus for receiving an air wave broadcast includes a TV, a computer, various kinds of air wave receivers, and the like, and the image device has a function of reserving a broadcast of a specific channel automatically at a specific time. That is, for example, if a user sets a desired time and channel in the reservation function of the TV, the power is automatically supplied when the corresponding reservation time arrives and the TV is turned on so that the broadcast of the reserved channel is displayed on the screen. To be printed. In this case, when the reservation information about the corresponding time and channel is input to the TV, the reservation information is stored in the built-in memory unit, and when the corresponding time is reached, the TV is turned on by controlling the power supply unit. In addition, the TV has a sleep function or an automatic off function, so that the TV is automatically turned off when the scheduled time comes while the user is watching the broadcast.

However, among the functions of the video cassette recorder in the past, there was no function of directly outputting the air broadcasting or reserving the air broadcasting to the video cassette recorder such as a TV, a monitor or an image output device. That is, when the video output device that cannot receive the air broadcasting is connected to the video cassette recorder by cable, it cannot receive the air broadcasting at all and cannot reserve the air broadcasting. In addition, many TVs can receive over-the-air broadcasting, but the TVs that turn on the power at a reserved time by reserving a desired time and channel are expensive. Therefore, only the recording function and the reserved recording function of the video cassette recorder could not reserve and record the over-the-air broadcasting, and there was a problem in that the video cassette recorder had to be connected to an image device capable of receiving the over-the-air broadcasting.

The present invention has been made to solve the above problems, the video cassette recorder by receiving the over-the-air broadcast of the reserved channel at the scheduled time to output the video to the TV or monitor, or video recording to enable recording The purpose is to facilitate the use of the recorder.

In order to achieve the above object, the present invention provides a step of supplying power to a TV or a monitor, inputting a time and channel reservation mode key using a remote controller, and setting and reserving a corresponding time and channel. Storing the input time and channel information in the memory unit; counting and checking the current time; determining whether the set time is reached; and when the set time arrives, the TV or monitor is turned on. Determining whether a state is in a state; supplying power when the TV or monitor is in an off state; determining whether a reserved channel is being broadcast when the TV or monitor is in an on state at a set time; and By providing a video cassette recorder time and channel reservation method comprising the step of changing to a reserved channel if it is not a reserved channel It can be achieved.

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

1 is a block diagram of a video tape history management apparatus of a video cassette recorder according to the present invention.

The remote controller 10 is composed of a plurality of keys on one side of the outside, a microcomputer is built in which a corresponding code or information is determined by determining the input of a key, and an oscillating unit for generating a wireless signal under the control of the microcomputer is built in. And a power supply unit for supplying power to the remote controller. In the remote controller 10 applied in the present invention, a reservation mode key for reserving over-the-air broadcasting of a desired time and channel is essentially configured. The key for the reservation mode for reserving the airwaves may use the same key as already configured on the remote controller 10.

The infrared receiver 12 is configured on one side of the video cassette recorder to receive and decode an infrared signal transmitted remotely from the remote controller 10. That is, the signal received from the remote controller 10 decodes the case where the information coded code is carried in the infrared signal or the infrared signal itself is coded.

The microcomputer 14 controls the operation of the video cassette recorder. The microcomputer 14 receives the decoded signal received by the infrared receiver 12 and outputs a control signal for controlling the video cassette recorder. The microcomputer 14 has a built-in timer for counting time or an external timer for driving the microcomputer 14.

The memory unit 18 inputs or outputs information data embedded as a control signal of the microcomputer 14, and a RAM or a ROM is used. The memory unit 18 incorporates information on the signal received from the remote controller 10 and various information on the control of the video cassette recorder.

The tuner unit 16 receives and tunes an airwave signal applied by wireless or wired. The tuner section 16 is a receiver including a circuit capable of selecting a desired transmission and tuning to its carrier frequency. The tuner section 16 includes an RF amplifier, a local oscillator, a mixer stage, and the like. The drive of the tuner unit 16 may be controlled by the microcomputer 14 or may output the driving state to the microcomputer 14.

The over-the-air signal processor 22 separates the over-the-air signals received by the tuner unit 16 into video and audio signals, and outputs them by demodulating, filtering, de-emphasis, and the like.

The output terminal 20 outputs the control signal input from the microcomputer 14 or the video signal input from the over-the-air signal processing unit 22 to a video output device such as a TV or a monitor. An adapter or a signal converter is used. . As the signal output from the output terminal 20, an audio / video (AV) signal and an airwave (RF) signal are output. In addition, the TV or monitor 22 visually represents or displays information input from the output terminal 20 through a cable or the like.

Although not shown in addition to such a configuration, it will be readily appreciated that an OSD (On Screen Display) processing unit for generating and outputting a text signal or a deck unit for mechanically driving a video tape is configured.

The time and channel reservation method of the video cassette recorder thus made will be described in detail.

FIG. 2 is a control flow diagram illustrating a time and channel reservation method of a video cassette recorder according to the present invention. In step S100, an externally supplied power is supplied to a TV or monitor 24 including a video cassette recorder. Let's do it. At this time, only the video cassette recorder may be turned on. However, the video cassette recorder may be turned on in order to visually recognize the reservation status by the character information output on the screen of the TV or the monitor 24. Turning on the power supply uses the remote controller 10 or operates a power switch configured in the video cassette recorder to supply power. In operation S101, a key for a time and channel reservation mode configured in the remote controller 10 may be operated to reserve a time and a channel desired by a user. In step S102, the time to be reserved and the broadcast channel are input by operating the remote controller 10, and the key signal input by the remote controller 10 is converted into an infrared signal and sent to the infrared receiver 12 of the video cassette recorder. The infrared receiver 12 decodes the received infrared signal and outputs it to the microcomputer 14, and the microcomputer 14 compares and determines the input signal in step S103, and stores the time and channel as reservation information in the memory unit 18. ).

In step S104, the reserved time is checked, and the microcomputer 14 counts the current time through the built-in timer to check the time set in the memory unit 18. In step S105, it is determined whether the microcomputer 14 has reached the reserved time. If the current time coincides with the time reserved in the memory unit 18, is the TV or monitor 24 turned on in step S106? If it is determined that the state is off, and outputs a control signal for turning on the power through the output terminal (20). Thus, in step S107, the TV or monitor 24 is switched from the off state to the on state. If the TV or monitor 24 is on or in the on state, it is determined whether the corresponding channel is reserved in step S108. If the corresponding channel is reserved, the received over-the-air broadcasting is output, but if it is another channel, the channel is changed to the reserved channel in step S109.

In this way, if the user reserves the desired time and channel with the video cassette recorder, the video cassette recorder when the TV or monitor 24 or the device which outputs the image does not receive the over-the-air broadcast, does not have a reservation function, or is turned off. Receives the over-the-air signal from the network so that the reserved channel is automatically turned on at the scheduled time.

As described above, the time and channel prediction method of the video cassette recorder of the present invention includes a tuner unit and an air signal processing unit for receiving an air signal in the video cassette recorder to perform air broadcasting to a TV or monitor connected to the video cassette recorder. Image processing can be performed to increase the function and convenience of the video cassette recorder.
