BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a videotape reproducing apparatus, and more particularly, to a videotape reproducing apparatus having a broadcast time display function capable of displaying the remaining broadcast time of a program when viewing a videotape.

The video tape reproducing apparatus reproduces the video signal while transferring the video tape from the supply reel to the reel at a predetermined speed during reproduction, and the video tape has 60 minutes, 90 minutes, 120 minutes, etc., depending on the tape length. Typically, the length of a video program recorded on a video tape is recorded shorter than the maximum recording length, and there are portions where the video program is not recorded back and forth. Therefore, when playing back and forth parts of a program in which such video signals are not recorded, noise appears.

Thus, the user calculates how much is left from the time of the start of playback from the time of the start of playback in order to know the display of the information on the actual broadcast length of the area where the video program is recorded and the indication of the current remaining length at the time of playback. This estimation is not only inaccurate but there is a problem that cannot be counted if the playback start time is not known.

In particular, when renting a videotape, since the airing time varies depending on the program, the user wants to know how much airing time is left during playback.

SUMMARY OF THE INVENTION An object of the present invention is to provide a video tape reproducing apparatus which can facilitate the use by inputting the airing time of a program before the start of reproduction to accurately display the remaining airing time at the time of reproduction, in order to solve the problem of the prior art.

A signal processing unit for processing a signal picked up through a playhead installed in the video signal and an audio signal, an on-screen unit for superimposing the on-screen signal on the video signal, and outputting the video signal output from the on-screen unit. When the display unit and the playback unit detect the presence or absence of a video signal during the playback operation, and the video signal starts to be reproduced and outputted, the countdown time is down counted from the broadcast time input through the input unit and the remaining time is transmitted through the on-screen unit. And a control unit for controlling the display unit to be displayed on the screen. .

The control unit may further include controlling to stop the reproducing operation when the airing time is down counted to zero, and may further include a function of controlling the rewinding operation in the reverse direction after the stopping operation.

In addition, another embodiment of the present invention is an input unit for inputting the airing time of a program recorded on the video tape, a deck unit on which the video tape is mounted, a servo unit for servo control of the motors installed in the deck unit, the deck unit A signal processor which generates a video signal and an audio signal by signal-processing the signal picked up by the playhead, a character display unit which displays the airing time input to the input unit, and detects the presence or absence of a video signal of the signal processor in the playback operation. And a control unit for controlling to display the remaining time down counting the airing time from the airing time input through the input unit when the video signal starts to be reproduced and output.

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

1 is a block diagram of a videotape reproducing apparatus according to the present invention.

An input unit 10 having a timer function for inputting the airing time of a program recorded on a video tape through a key input or a remote controller installed in the front of the parent set of FIG. 1, a deck unit 20 on which the video tape is mounted, and A servo unit 30 for servo control of drum motors and capstan motors installed in the deck unit 20 and a signal picked up through the reproduction heads installed in the deck unit 20 are processed to generate a video signal and an audio signal. A signal processor 40, an on-screen unit 50 that superimposes the on-screen signal on the video signal, and outputs the video signal output from the on-screen unit 50; In operation, the presence or absence of a video signal of the signal processing unit 40 is detected by detection of a synchronization signal, and when the video signal starts to be reproduced and outputted, it is broadcast from the airing time input through the input unit 10. And a control unit 70 for controlling to display on the screen of the display unit 60 and the counting down the remaining time to cross through ounce Cri Snaps 50.

The control unit may further include a function of controlling to stop the playback operation when the airing time is down counted to zero and a function of performing a reverse rewinding operation after the stop operation.

2 is a flowchart for explaining the airtime display operation according to the present invention. Referring to this, the operation of the present invention will be described.

First, the broadcast time of the program described on the label of the rented video tape is viewed, and this time is input to the input unit 10 by the remote controller (step 100).

After inserting the video tape and pressing the play key to execute the play operation, the noise is displayed in the initial portion without a signal, and the video signal starts to be displayed from the portion where the video signal is loaded. In this way, when the video signal starts to be reproduced normally, the synchronization signal is detected and the initial part of the program can be detected by detecting the presence or absence of the synchronization signal (step 102). When the synchronization signal is detected, the counting time is inputted every time the synchronization signal is input (step 104). On-screen data corresponding to the remaining time is generated to generate a video signal through the on-screen unit 50. The time display on-screen signal is superimposed and displayed on the screen of the display unit 60 (step 106). The display on the screen is preferably an area which does not overlap with the subtitle display area and is displayed on the upper left of the screen.

Subsequently, it is detected whether the time remaining after counting down becomes zero (step 108). Otherwise, the operation 104 is performed and if it is zero, the playback operation is stopped and the automatic rewind is performed, and then the tape is ejected and terminated (step 110). Here, the additional operations after the regeneration stop are not performed when the user inputs another function key, but performs an operation according to the input function key. These additional features will also be optional at design time.

In the block diagram of FIG. 3, the same parts as those of the block diagram of FIG. 1 described above are denoted by the same reference numerals and detailed description thereof will be omitted. The difference is that since the quality of the screen is lowered when the screen of the display unit 60 is displayed, the remaining time of the airing time is displayed on the character display unit 80 composed of a fluorescent display tube installed in the front panel. The character display unit 80 is configured to perform character display or time display on function keys in normal times, and to display the airing time according to the present invention during reproduction.

As described above, according to the present invention, the broadcast time of the videotape is set in advance and displayed while the broadcast time is reduced according to the play time, so that the user can easily and accurately check how much time is left in the future while watching.
