KR19980041343A - How to set the recording length of VRF - Google Patents

Abstract

The present invention relates to a method for setting a recording length of a V-CAL, which is suitable for easily setting a recording length of a V-C. In the V-C according to the prior art, an OTR recording length is described by pressing a specific key continuously. For example, since the OTR recording length is selected in the order of 30 minutes-60 minutes-90 minutes, the larger the OTR recording length is, the more it is inconvenient to press the key several times. By directly pressing the key, the OTR recording length can be set quickly and accurately, so that the convenience of setting the OTR recording length is increased, thereby improving the above-described drawbacks.

Description

How to set the recording length of VRF

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for setting a recording length of a V-C, and more particularly, to a method for setting a recording length of a V-C.

Briefly, the principle of the Video Cassette Recorder is as follows.

We can easily call it VSI, but it was originally called Video Cassette Recorder, which is the correct name. In Korean, it can be called 'self-recording playback'.

It is a device that records video signals from the outside and records them on tape through the head of VRC.

Here, the head is a kind of electromagnet, which causes a change in the magnetic force according to the electric change, and is recorded by contacting the tape emitting head with the magnetic signal.

At this time, the tape is iron powder coated on the vinyl, the iron powder is magnetized according to the change of the magnetic force of the head.

You can also select the recording speed of VRF.

The recording speed can be divided into standard speed (SP mode) and triple speed (SLP mode or EP mode: 6 hours of use for 2 hours tape).

If you don't have important recordings, you can record at three times the speed, but the video quality is lower than standard speed recording.

In addition, there are two types of home VRs, β type and VHS (Video Home System) type. The basic concept of the two types is the same, and the tape used is 1/2 inch wide.

In this regard, the OTR recording length in the VRC according to the prior art selects the OTR recording length in the order of, for example, 30 minutes-60 minutes-90 minutes by pressing a certain key consecutively. The larger the recording length is, the more inconvenience it is to press the key several times.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art, and when the OTR recording length setting of VRC is directly pressed, the VTR recording length setting method can be set quickly and accurately. The purpose is to provide.

In order to achieve the above object, the present invention provides a command input unit for inputting a key to select a desired function of MI, and a micom for controlling a corresponding function of VCC according to a key input of the command input unit, and a control of micom. A deck that operates the video tape to operate the video tape, a tuning unit that operates under the control of the microcomputer to tune the desired broadcast signal, and an OSD (on screen display) processes the shape by operating under the control of the microcomputer. It comprises a OSD processing unit.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

Referring to FIG. 1, FIG. 1 is a block diagram for applying a recording length setting method of a V-C according to the present invention, and includes a command input unit 10 for inputting a key to select a desired function of a V-C, and the above-described command. The microcomputer 20 which controls the corresponding function of V-Cal according to the key input of the input part 10, the deck 30 which operates under the control of the microcomputer 20 mentioned above, and drives a video tape, A tuning unit 40 operating under control of 20) to tune a desired broadcast signal, and an OSD processing unit 50 operating under the control of the microcomputer 20 to OSD-process the corresponding shape.

The present invention thus made will be described in detail with reference to FIG. 2 as follows.

First, the user operates a key of the command input unit 10 to select a desired function of the V-SR to be executed by the user.

Next, the microcomputer 20 controls the corresponding function of the VRC according to the key input of the command input unit 10 described above, and the deck 30 operates under the control of the microcomputer 20 described above to load the tape. Drive the recorded video tape to perform an operation such as playback or recording.

At this time, the types of loading may include cassette loading and tape loading. First, cassette loading means that a video tape cassette is loaded into the deck, and tape loading means that after the cassette loading, the tape is drum. Means loaded to the side.

In addition, the tuning unit 40 operates under the control of the above-described microcomputer 20 to tune a broadcast signal desired by a user among a plurality of broadcasting signals, and the OSD processing unit 50 under the control of the microcomputer 20 described above. By operating the OSD on the corresponding shape, the OSD is executed on the current screen.

Figure 2 is a flow chart showing step by step an embodiment of a recording length setting method of V-Cal according to the present invention.

First, the microcomputer 20 performs OSD processing of a guide message for the OTR mode when the VRC is in the OTR mode, and selects a desired OTR recording time using one corresponding key input from a plurality of specific keys of the command input unit 10 described above. To set (110,120).

Next, in the above-described steps 110 and 120, even when the VR is not in the OTR mode but in the recording mode, the VTR is set to the OTR mode so as to OSD-process the guide message for the OTR mode, thereby selecting one of the plurality of specific keys of the command input unit 10 described above. Set the desired OTR recording time with the corresponding key input (130, 140).

In this case, a digitron may be used instead of OSD processing the guide message for the above-described OTR mode.

As described above, in the present invention, the OTR recording length can be set quickly and accurately by directly pressing a corresponding key when setting the VTR OTR recording length, thereby increasing the convenience according to the OTR recording length setting, thereby improving the added value of VRT. It is effective.

Claims (1)

A first step (110, 120) of OSD processing the guide message for the OTR mode to set a desired OTR recording time with one corresponding key input among a plurality of predetermined keys when the VR is in the OTR mode; After performing the first step (110, 120), if the V-CAL in the recording mode in the step (110, 120) is set to the OTR mode by setting the OSD message for the OTR mode OSD of one of the plurality of specific keys A method of setting the recording length of V-CAL, which is performed by sequentially performing the second step (130,140) for setting the desired OTR recording time by the corresponding key input.
