BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a count review apparatus for a reservation recording program in a VCR having an On Screen Display (OSD) function.

In general, the timer value is not displayed or stored by the timer microcomputer after the scheduled recording of the existing VCR system is completed.

Therefore, when the user wanted to play the video after the reservation recording was completed, it was not easy to find the specific part recorded.

In order to alleviate such troubles, a system having an added function such as an index system has appeared, but there is a problem in visualization that can be identified by the user's naked eye.

Accordingly, it is an object of the present invention to provide a count review device for a reservation recording program that stores and displays count values of the start and end portions of a reservation recording portion so that a search can be made.

In order to achieve the above object, the present invention calculates and stores a pulse signal generated from a system control or a reel sensor as a count value in a timer microcomputer, and displays it on a monitor using an OSD IC.

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

1 is a block diagram of a general VCR system.

The microcomputer 10 performs control on display as a timer microcomputer, key input from the key matrix 15, a clock function, a reservation of reservation recording, and a storage function.

In addition, according to the present invention, the timer microcomputer 10 calculates and stores count values of the beginning and the end of the recorded program.

The microcomputer 20 receives and transmits information regarding the timer microcomputer 10, the key input state, and the deck unit 25 as a system control microcomputer. In addition, a signal for driving the deck portion 25 is provided.

The deck section 25 reproduces and records the tape under the control of the microcomputer 20 and outputs the signal.

The image processing unit 27 transfers the external and TV signals to the deck unit 25 by switching the recordable signal or bypasses the next OSD IC 17 to process the playback signal from the deck unit 25.

The OSD IC 17 text-processes the image from the image processor 27 and the information from the microcomputer 10 and finally outputs it to a monitor (not shown).

The OSD IC 17 also displays the count value stored in the microcomputer 10 in accordance with the present invention. Line 1, on the other hand, is a control line for OSD display and gives information about the display to the OSD IC 17.

The line 2 is information exchange means of the timer microcomputer 10 and the system control microcomputer 20, and transmits information on the system status to the timer microcomputer 10, and transmits the input state of the key to the system control microcomputer 20. do.

The line 3 is a means for exchanging information between the system and the system control, and is actually a communication means for driving the deck section 25.

Line 4 is an F / R line, when the signal is high, the tape travels in the + direction, and when the signal is low, the tape travels in the-direction.

The line 5 is a signal for picking up a control signal recorded on the tape as a control input line, and increases and decreases as the tape travels.

The present invention calculates a count value in two ways.

The first method is to use a control pulse called a real time counter.

In this method, the system control microcomputer 20 outputs servo control pulses to the deck unit 25 in a period of 30 ms in the recording mode.

This signal is recorded on the tape via digital analog (D / A) conversion.

Therefore, at this time, the count value of one unit is increased every 20 control pulses generated, and the value is transmitted to the timer microcomputer 10 for storage.

Regeneration will be performed in the reverse order.

The second method uses a reel pulse, which is because the reel sensor (not shown) has 12 black parts.

That is, each reel turns 12 pulses.

It counts this and causes the timer microcomputer 10 to store and read the value.

Therefore, when scheduled recording is performed using either method, the timer microcomputer 10 stores the count value at the time of performing the recording and the count value at the end.

In addition, the internal memory means (not shown) of the microcomputer 10 monitors by the OSD IC 17 by storing information about the start and end count values of the recorded contents, the recorded broadcasting channel number, the number of recorded programs, the recording speed, and the like. It can be displayed on the screen, and the user can easily find the appropriate part of the recorded contents by viewing it.

Referring to FIG. 2, there is shown a flowchart relating to a method of storing count values during reservation recording according to the present invention.

First, when you want to see the contents of the recording program according to the present invention set by the key matrix 15 and the timer micom 10 in step S1, press the counter review (hereinafter abbreviated as C / R) key of the remote controller. When the specific code is input to the microcomputer 10, the count value recorded by the OSD IC 17, the recorded content (i.e., the channel number), the recording speed, and the like are displayed on the monitor in step S5.

In step S2, when the C / R key is pressed again to reduce the number of keys, the C / R mode is terminated through steps S3 and S4.

If you specify the desired number while looking at the number of the program displayed on the monitor in step S6, it is determined in step S7 whether or not the reserved recording is completed and then goes to the high speed mode to the start counter corresponding to the number.

In detail, in step S8, if the value is smaller than the count value, the fast forward (FF) operation is performed (step S9), and if it is larger than the count value (step S10), the fast rewind operation is performed. .

In the above step S7, it is also possible to provide an indication of "not recorded" if it is not a reserved recording completed number.

Now, in step S11, if the result count values of steps S8, S9, and S10 have been reached, the mode advances to the playback mode (step S12), and when the playback ends, the C / R mode is released (step S13).

As described above, according to the present invention, the count value of the beginning and the end of the tape is stored in the timer microcomputer during reservation recording, and if necessary, it is easy to review a specific part by displaying it using the OSD IC. .
