Automatic Videotape Playback in Television-Video Cassette Recorders

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of automatically playing a video tape of a television-video cassette recorder (TVCR) (hereinafter referred to as a TVCR), and in particular, a video in a deck even when an automatic channel setting function is performed. It is about a method to stop the automatic channel setting function that is being performed by one-touch operation of inserting a tape and to play back the recorded contents on the video tape.

In general, a video cassette recorder (VCR) (hereinafter referred to as a 'VCR') reads video and audio signals recorded on a video tape, which is one of magnetic tape-type storage media. Refers to a device that plays back or records video and audio signals on a videotape. To operate such a VCR, a display device such as a television is required. It came to showcase the unified TVCR.

The TVCR includes functions of a VCR as well as functions of a conventional television, and examples thereof include an automatic channel setting function in a television and an automatic playback function in a VCR.

Accordingly, the user can set all the broadcast channels that can be tuned by pressing the channel setting key provided in the key input unit (or the remote controller) to execute the automatic channel setting function, and later use the channel increase / decrease key provided in the key input unit. In addition, it has enjoyed the convenience of freely tuning the broadcast channel, and also has the convenience of playing and viewing the contents recorded on the videotape just by one-touch operation of inserting the videotape into the deck by the automatic playback function.

In the TVCR, however, unlike the individual devices that exist separately, there is an undefined situation in which the automatic playback function should be performed when the video tape is inserted during the automatic channel setting function. The situation is different, and can be divided into the following cases.

First, if the video tape is inserted in the deck while the auto channel setting function is being executed, the auto play function is not performed.

Secondly, when the automatic channel setting function is stopped and the auto play function is executed.

The user may feel uncomfortable under any of the above circumstances. In the first situation, the auto play function is performed even if the user intentionally inserts a video tape into the deck with the auto play function in mind while the auto channel setting function is being performed. In this case, the user has to inconvenience the contents recorded on the videotape through arbitrary operations.

In the second situation, the automatic channel setting function that was performed when the video tape was inserted into the deck for recording is stopped regardless of the playback, and the video tape is played back. The hassle and time wasted to execute the automatic channel setting function again.

Accordingly, an object of the present invention is to enable the user to stop the automatic channel setting function which is being performed by the one-touch operation of inserting the video tape into the deck even when the TVCR is performing the automatic channel setting function, and to play the recorded content on the video tape. In addition, the present invention provides a method of automatically playing a video tape, and furthermore, automatically playing a video tape having no recorded content is meaningless. Therefore, the video tape automatically determines whether a video tape is recorded and performs an automatic playback function accordingly. Its purpose is to provide a regeneration method.

The present invention for achieving the above object, if the video tape is inserted into the deck during the automatic channel setting function for setting the selectable broadcast channels in the TVCR, the presence or absence of a safety tap to prevent recording on the video tape After that, according to the result, the automatic channel setting function is stopped and the contents recorded on the video tape are reproduced.

Here, when the safety tab is removed from the video tape, the automatic channel setting function is stopped and contents recorded on the video tape are reproduced, but if the safety tab is present on the video tape, the automatic channel setting function is continued.

The present invention indirectly determines the presence or absence of contents recorded on the videotape through the presence or absence of a safety tab, and according to the result, the automatic channel setting function is continued or the automatic channel setting function is stopped and the automatic playback function is Therefore, since the content recorded on the videotape is played back, the user can operate the TVCR satisfactorily with minimal operation.

Hereinafter, the present invention will be described in detail with reference to preferred embodiments.

1 is a block diagram schematically showing a configuration of a general TVCR for use in the description of the present invention.

For reference, referring to the general operation of the TVCR through FIG. 1, when the user wants to watch a television broadcast by operating the key input unit 20, the Micom 10 receives a signal received through an antenna ANT. The tuner 60 tunes to the tuner 60, and at this time, the microcomputer 10 controls the PLL (Phase Lock Loop) unit 50 to change the tuning voltage of the tuner 60. At this time, the microcomputer 10 controls the On-Screen Display (OSD) unit 70 to display the number of the tuned channel on the monitor 100.

On the other hand, if you want to watch the contents recorded on the video tape by operating the key input unit 20, the microcomputer 10 recognizes this to control the deck 30 and Servo (40) and RF (Radio Frequency) converter The controller 80 controls the signal recorded on the video tape to be processed by the video block 90 and displayed on the monitor 100.

2 is a flowchart illustrating a video tape automatic playback method in a TVCR according to the present invention.

In this case, performing the automatic channel setting function (S10), checking whether the setting is completed by the automatic channel setting function (S20), and the video tape in the deck during the automatic channel setting function is performed. Checking whether it is inserted (S30), checking the presence or absence of a safety tab on the video tape (S40), and stopping the automatic channel setting function being performed when the safety tab is removed (S50); And reproducing the contents recorded on the video tape (S60).

Here, if the safety tab is present as a result of checking whether the safety tab exists, the process proceeds to the step of performing the automatic channel setting function again (S10) and continues the automatic channel setting function.

Looking at the process of the video tape automatic playback method having such a configuration implemented through the TVCR shown in Figure 1 as follows.

When the user inputs the channel setting key provided in the key input unit 20 to execute the automatic channel setting function, the microcomputer 10 generates different tuning voltages through the PLL unit 50 to receive the antennas through the antenna ANT. Automatic channel setting is performed by tuning to different broadcast signals, and storing all tuned channels in the memory 110 in this manner. (S10, S20)

When the channels are set as described above, the user may later select the next channel closest to the currently tuned channel using the channel increase / decrease key provided in the key input unit 20.

While performing the automatic channel setting function as described above, the microcomputer 10 checks whether or not the video tape is inserted into the deck 30, and when the video tape is inserted into the deck 30, the microcomputer 10 ) Checks the presence or absence of a safety tab on the video tape to prevent recording, and indirectly determines whether there is recorded content on the video tape (S30, S40).

If the safety tab is present on the video tape as a result of checking whether the safety tab is present, the microcomputer 10 determines that there is no recorded content on the video tape inserted in the deck 30 and continues the automatic channel setting function that was being performed. The process is repeated until the channel setting is completed (S10 to S40).

In addition, if the safety tab is removed from the video tape as a result of checking whether the safety tab is present, the microcomputer 10 determines that there is recorded content on the video tape inserted in the deck 30, and performs the automatic channel setting function that was being performed. Stop, control the deck 30 and the servo 40 to read the video signal recorded on the video tape, RF conversion and processing through the video block 90 to display through the monitor 100 to record on the video tape The contents are played back (S50, S60).

As described above, according to the present invention, even if the automatic channel setting function is being performed, the one-touch operation of inserting the video tape into the deck can stop the automatic channel setting function being performed and play back the recorded content on the video tape. It is convenient.

In particular, it is possible to satisfactorily operate TVCR with the minimum operation by preventing the unnecessary operation by indirectly discriminating the recorded contents through the presence of the safety tab on the video tape and performing the automatic playback function accordingly. .
