How to display the remaining tape when performing VTI's OTIAL function

The present invention relates to a method for displaying the remaining amount of tape on the OSD screen when the remaining amount of recording tape is insufficient when the OTIAL function is set in the VSI recording mode.

In general, a recording method of a television broadcast program using VSI can be roughly divided into an immediate recording method and a reserved recording method.

The instant recording method refers to a method in which a television viewer presses the recording button of VSI to execute the direct recording when the TV viewer wants to record the program currently being viewed while watching a broadcast program. It is a recording method that can accurately record the desired broadcast program even when you are away by programming and registering the recording condition in advance to record the broadcast program.

In addition, when a user wants to record a TV program while watching a TV, the OTT (One Touch Recording) time setting method is used. .

This oral recording method is useful for recording a desired amount of time while watching television.

The process of registering OTIAL recording setup is as follows.

If you want to record a broadcasting program of a specific channel while the power of VSI is on, insert the tape into VSI and then select the desired channel for recording by pressing the channel selection key or number key on the remote control. .

Following the channel selection step, pressing the recording speed selection key on the remote controller selects one of the standard speed and the triple speed.

Following the recording speed selection step, the user selects a desired simple reserved recording time by pressing an oral key provided on the body of VSI.

Table 1 shows an example of the time change table according to the oral key operation for setting the oral time.

Button presses Display status Operating status 1 press current time Recording continues until the stop button is pressed Press twice End 0:30 30 minutes from the current time 3rd time End 1:00 Recorded 1 hour 4 times Shutdown 1:30 Recorded for 1 hour 30 minutes 5 times End 2:00 Recorded 2 hours 6 times Shutdown 2:30 Recorded for 2 hours 30 minutes 7 times Shutdown 3:00 Recorded 3 hours 8 times Shutdown 3:30 Recorded for 3 hours 30 minutes 9 times End 4:00 4 hours recorded 10 times current time Recording continues until the stop button is pressed

As you can see, recording time is extended by 30 minutes each time you press OTIAL key, you can set up to 4 hours recording time very easily.

However, in the conventional method of setting the time for the oral tear as described above, there is a problem in that the recording fails when the remaining amount of the video tape inserted in the V'Dial deck portion is less than the amount of the oral recording time set by the user.

Accordingly, an object of the present invention is to display the remaining tape on the OSD screen when the remaining recording tape is insufficient when the OTIAL function is set in the VSI recording mode so as to prevent the recording failure due to insufficient tape remaining when the OTI function is set. The purpose of the present invention is to provide a method of displaying the remaining tape amount when performing an oral function of VSI.

In order to achieve the above object, the present invention provides a method of determining whether or not the OTIAL key of VSIAL has been input in the recording mode of VSI, and if the OTIAL key is determined at the step, the current recording tape remaining time and OTIAL Checking the set time; and determining whether the remaining recording time of the recording tape is less than or equal to the OTAL setting time; and if the remaining recording time of the recording tape is less than the OTAL setting time, Outputting an OSD character to the receiver, executing the OTIAL operation when the step is completed, determining whether the OTIAL operation has ended after a predetermined time has elapsed, and wherein the OTIAL operation has ended in the step. If it is determined that the step of blocking the OSD text output VSI microcomputer It is characterized in that it carried out sequentially.

Hereinafter, a method of displaying the remaining tape amount when performing the oral function of VSI according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic circuit diagram of a VSI system for implementing the present invention.

As referred to herein, the microcomputer 10 is connected to control the deck unit 30 by receiving an input signal from the key input unit 20 for generating a key input signal.

An external input signal such as a broadcast program is tuned through a tuner (not shown), and then output as a video signal through the video signal processor 40 and the OSD processor 50.

On the other hand, during recording, the external input signal is recorded on the tape via the video signal processor 40 and the preamplifier 60.

2 is a flowchart illustrating a method of displaying a remaining tape amount when performing an oral function of VSI according to the present invention.

In other words, the flowchart is a step (step 101) of determining whether an oral key of VSI has been input, and a step of checking a current remaining time of the recording tape and an oral set time if it is determined that the oral key is input (step 102). Determining whether the remaining recording time of the recording tape is less than or equal to the OTI setting time (step 103); and if the remaining recording time of the recording tape is less than or equal to the OTAL setting time, Outputting an OSD character to the receiver (step 104), executing the Otral operation when the step is completed (step 105), and determining whether the Otral operation is finished after a predetermined time has elapsed (step 106), and if it is determined that the OTIAL operation has been completed in the above step, blocking of the OSD text output is performed (step 107).

The process of the present invention configured as described above is described in more detail as follows.

First, when a user tunes and watches a television broadcast program by operating the key input unit 20, the microcomputer 10 causes the tuner to tune the signal received through the antenna. At this time, the microcomputer 10 controls the phase lock loop to change the electronic tuning voltage of the tuner.

Accordingly, the tuned broadcast program processed by the intermediate frequency is output to the TV receiver through the video signal processor 40. At this time, if the user wants to record the tuned broadcast program, the user presses an OTI key.

For reference, the recording time is extended by 30 minutes each time the orial key is pressed.

Subsequently, the VSI microcomputer 10 first determines whether or not the OTIAL key has been input by the user (step 101). At this time, if it is determined that the OTIAL key has been input, the current amount of tape remaining from the reel sensor of the deck unit 30 side is determined. The information is received to check the remaining tape time and the setup time of the oreal (step 102).

Subsequently, the microcomputer 10 determines whether or not the remaining amount of recording tape time is less than or equal to the OTAL set time (step 103). At this time, when the remaining amount of recording tape is less than or equal to the OALD time, the OSD processing unit 50 In step 104, the control tape is sent to the controller to output the remaining amount of the recording tape through the TV receiver.

At this time, the remaining tape amount is preferably represented by the remaining tape time data so that the user can quantitatively calculate.

On the other hand, when all of the above steps are completed, the control unit sends a control signal to the deck unit 30 (step 105). After a predetermined time has elapsed from the time of executing the oral operation, the microcomputer 10 ends the oral operation. It is determined whether or not it is (Step 106).

If it is determined that the OTAL operation is completed in this step, the control signal is sent to the OS processing unit 50 to block the OSD text output (step 107).

As described above, the present invention displays the remaining tape on the OSD screen when the remaining recording tape is insufficient when the OTIAL function is set in the VSI recording mode, thereby preventing the recording failure due to the remaining tape remaining when the OTI function is set. can do.
