Description

How to eject VRT's video tape

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a VCR (Video Cassette Recorder; hereinafter abbreviated as VRC), and is particularly suitable for automatically ejecting a video tape when all recorded signals recorded on the video tape are played back. A method of ejecting a video tape from a seed.

In general, when a user wants to record a broadcast program displayed on a TV on a video tape, the user turns on the VRC connected to the TV, and when the desired broadcast program starts, a recording button provided on the own panel or the remote control of the VRC. You can record the program by entering (Record Button).

In recent years, for the convenience of the user, VRT has replayed all the recording signals recorded on the video tape, and then rewinds to the beginning of the video tape when the end of the video tape is detected through the end sensor. When the first stage of the video tape is detected through the start-sensor, the video tape can be ejected to turn off the V-Cal.

On the other hand, if a video tape is rented through a video rental store or the like and then all the recording signals recorded on the video tape are watched, most users do not wait for the automatic ejection function as described above to be performed. By operating the stop key on its own panel, the playback of the videotape is stopped, and the ejection of the videotape inserted in the VCA by the eject key is operated.

Therefore, the present invention has been devised in view of the above-mentioned point, and when all the recording signals recorded on the video tape are reproduced by selection from the outside, the video tape is automatically ejected, and then the power of the VRC is cut off. The purpose is to provide a method of ejecting a video tape of VSI.

In order to achieve the above object, the present invention provides a method for ejecting a video tape inserted in a V-C, comprising: an eject for ejecting the video tape immediately after the reproduction of a recording signal recorded on the video tape from a key input unit is finished. When the mode is selected, the first step of OSD processing the corresponding message and then displaying it on the screen, reproducing the recording signal recorded on the videotape, comparing the envelope of the reproduced reproduction signal with a predetermined predetermined level In the second step, and in the second step, when the envelope of the reproduction signal is less than the predetermined level for a predetermined time, ejecting the inserted video tape, and then turning off the VSR. VCD video tape ejection method characterized by consisting of steps Provided.

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

1 is a schematic block diagram of hardware for performing a video tape ejection method of a VR in accordance with the present invention. The key input unit 110, the sensor unit 120, the microcomputer 130, the servo unit 140, OSD (On Screen Display; abbreviated as OSD) drive unit 150 is configured.

In Fig. 1, the key input unit 110, in response to the user's operation signal, rewinds and then ejects the video tape by the end of the video tape, and when both of the recording signals recorded on the video tape are reproduced. The microcomputer 130 provides a key signal for selecting an eject mode for ejecting a video tape, and the sensor unit 120 is composed of an end sensor, a start sensor, and a tape detection sensor. The sensing signal is provided to the microcomputer 130.

Then, the microcomputer 130 generates a control signal for ejecting the video tape inserted in the V-Cal in a mode corresponding to the mode selection key signal from the key input unit 110, while the sensor unit 120 in the automatic eject mode. Generate a control signal for ejecting the video tape inserted in the VRC based on the detection signal from

In addition, the servo unit 140 plays back and fast-rewinds the video tape inserted in the VRC based on the control signal from the microcomputer 130, and the OSD driver 150 controls the control signal from the microcomputer 130. In accordance with the OSD, a message corresponding to the eject mode is processed and displayed on a screen not shown.

With reference to Figs. 1 to 2 will be described in more detail with respect to the operation of the recording method of the VR in accordance with the present invention through the hardware consisting of the above-described components.

First, when the user inserts the video tape into the V-Cal (step 205), a detection signal is provided to the microcomputer 130 from the tape detection sensor in the sensor unit 120, and the microcomputer 130 from the key input unit 110. It is checked whether the reproduction key signal is continuously provided for a predetermined time (for example, 3 seconds) set (step 210).

As a result of the check in step 210, if the playback key signal is not continuously input from the key input unit 110 for 3 seconds, the microcomputer 130 controls to perform the automatic eject mode for detecting and ejecting the end of the video tape. Generate a signal.

Specifically, on the basis of the control signal for reproduction from the microcomputer 130, the recording signal recorded on the video tape is reproduced through the servo unit 140 (step 215), and after the reproduction of the video tape is finished, When the end of the video tape is detected through the end sensor in the sensor unit 120, the playback of the video tape through the servo unit 140 is stopped based on the control signal for stopping from the microcomputer 130, the microcomputer 130 Fast rewinding of the video tape is performed via the servo unit 140 based on the control signal from the step (step 220, 225).

During the fast rewinding in the step 225, if the first end of the video tape is detected through the start sensor in the sensor unit 120, the video tape inserted in the VRC is based on the control signal from the microcomputer 130. After being ejected (step 255), the power of the VRC is cut off (step 260).

On the other hand, if the playback key signal is input through the key input unit 110 for more than 3 seconds as a result of the check in step 210, the microcomputer 130 generates a control signal for displaying the eject mode, and from the microcomputer 130. The message corresponding to the eject mode is OSD processed through the OSD driving unit 150 based on the display control signal of (S235) and then displayed on a screen (not shown) (step 235).

Then, on the basis of the control signal for reproduction from the microcomputer 130, the recording signal recorded on the video tape inserted in the V-CAL via the servo unit 140 is reproduced (step 240).

At this time, the microcomputer 130 compares the envelope of the reproduction signal reproduced from the video tape with a predetermined level, and if the envelope of the reproduction signal is equal to or less than the predetermined level, the predetermined time (for example, 10 seconds) is reached. If the elapsed time (steps 245 and 250) exceeds 10 seconds in the state where the envelope of the reproduction signal is less than or equal to the predetermined level, the video tape inserted in the VRC is based on the eject control signal from the microcomputer 130. After being ejected (step 255), the power of the VRC is cut off (step 260).

As described above, when the eject mode is selected through the key driving unit 110, the eject mode is OSD processed through the OSD driving unit 150, and then displayed on the screen, and the envelope of the reproduction signal reproduced from the video tape is preset. If a predetermined time (10 seconds) is exceeded in a state smaller than the level, the video tape inserted in the VRC is ejected based on the eject control signal from the microcomputer 130, and then the VSR is cut off.

Therefore, according to the present invention, when watching or wishing to rent a videotape, if all the recording signals recorded on the videotape are played back, the videotape is automatically ejected, and then the power of the VRC is cut off, so that the user In addition to the convenience of use, it is possible to prevent the waste of power.
