Description

How to handle zero-stop memory in the vial system

The present invention relates to a means for enabling reproduction at a zero-stop correct position in a video cassette recorder (hereinafter referred to as VCR) system in which zero-stop is set during recording / playback, Function, it is possible to eliminate the inconvenience of searching for the first part of the pros because the user can not find the zero-stop point when re-charging the discharged eject tape when the eject key is pressed by the user unintentionally after recording the tape.

The Vishali system is a device that records and reproduces video / audio signals provided by various video sources (video camera, cable broadcasting, air broadcasting, etc.).

The VISIAL system has a VISS (VISS INDEX SEARCH SYSTEM) function that records the position information of the tape at the time of recording of the tape. It records a predetermined signal when recording a video tape, and when the recording is completed, And to perform a quick search for the first part of the recorded program.

Conventionally, there are three methods for searching for a predetermined program recorded on a tape. In the case of the above-mentioned service function, there is a method of searching through a menu of OPTION menu → selecting a tape function → an index → → reproduction step, (REW) → stop → playback step. On the other hand, the counter method is to set the pre-recording counter to 0:00:00, Go to 0 → → → step to go to the selection process was done.

Therefore, such a conventional VISCAR system has a problem in that it is necessary to rewind to see the recorded program after the recording is finished and to search for the recording start point by the complicated operation as described above.

This means that after the recording is completed, the vial system is automatically turned off, so that the user can not return to the initial recording section until the user selects the rewind mode. When performing the rewind mode automatically, It was possible only when I drove to the end.

Conventionally, a method of performing automatic rewinding to a portion where recording is started when the recording is completed in the recording mode is disclosed in Korean Patent Publication No. 3753, Patent Publication No. 94-8878.

As shown in FIG. 1, the key matrix unit 7 includes keys related to the program reservation recording of the Vsial system and various keys related to the operation mode of the Vsial system. The timer microcomputer 10 receives the key signal Detects a key input signal transmitted from a certain key by scanning, and transmits the key data to the system controller / servo microcomputer 15 in series.

The program recording time, the end time, the desired broadcast channel, etc. input by the user through the key metrics unit 7 are recorded in the timer microcomputer 10, and generally, the program reservation recording setting includes a plurality of different programs You can make reservations.

The systonic / servo microcomputer 15 is a means for controlling the overall control of the Vishal system and the servo apparatus. The systonic / servo microcomputer 15 operates the deck unit (not shown) in the corresponding mode according to the key data transmitted from the timer microcomputer 10 .

In addition, the signal corresponding to the corresponding mode decoded by the system / servo microcomputer 15 is serially provided to the timer microcomputer 10 so that the timer microcomputer 10 can display various modes have.

The control signal recording section 3 provides a control signal for outputting a bismark signal from the control signal recording section 3 by advancing the deck section in the recording mode in the recording mode, In response to the control signal from the servo microcomputer 15, the control head 9 provides a bismark signal to cause the bismark to be recorded at the beginning of the tape to be reserved.

On the other hand, the SISCON / servo microcomputer 15, which receives a signal indicating the scheduled recording completion time from the timer microcomputer 10, causes the deck unit to be performed in the rewind mode. During the rewind mode, the control head 9 reads the bismark signal together with the control signal from the tape, and the read bismark signal is transmitted to the amplifier 7.

The bismark signal appropriately amplified by the amplifier 7 is transmitted to the control circuit / servo microcomputer 15, and the control circuit / servo microcomputer 15 judges that it is the recording start portion of the tape in accordance with the signal and stops the deck unit State (stop mode).

2 shows a method of automatically rewinding after a specific program scheduled recording in the conventional system as described above. In this case, the timer microcomputer 10 continuously checks the recording start time in a state that it is in the program scheduled recording mode Steps S1 and S2). When the timer microcomputer 10 transmits the key data related to the recording to the system controller / servo microcomputer 15 when the recording start time is reached, the system controller / servo microcomputer 15 advances the deck unit to the recording mode And a bismark signal is output by providing a control signal to the control signal recording unit 3. [

At this time, a bismark is recorded for a predetermined time, for example, about 5 seconds by the control head unit 9 via the control signal recording unit 3 (step S3).

The timer microcomputer 10 continuously checks the recording end time and notifies the status of the recording to the system control microcomputer 15 at the end of the recording time so that the control microcomputer 15 causes the recording / Mode is stopped, while the number of reserved programs (PGM) is decremented by one, and it is continuously checked whether or not there is a program to be further scheduled to be recorded (steps S4, S5, S6).

If there is no more reservation program, that is, if the value of the temporary register X becomes zero, the process proceeds to the next step. The above-described steps are useful for a plurality of programs scheduled recording, and are particularly suitable for scheduled recording of a short-length program for a short period of time.

The timer microcomputer 10 judges that there is no more scheduled program to be recorded thereafter and causes the sheath / servo microcomputer 15 to perform the rewind mode, and therefore, under the control of the sheath / servo microcomputer 15 A bismark can be detected together with a control signal from the control head 9 while the rewinding mode is being performed.

In addition, in the above, the detected bus signal is amplified by the amplifier 5 and then transmitted to the cisco / servo microcomputer 15, and when the cisco / servo microcomputer 15 has one program reserved for recording You will proceed to stop mode. However, if one or more programs are scheduled to be recorded, as in steps S5 and S6, the system / servo microcomputer 15 compares the number of reserved programs with the number of detected bism marks, Repeat from S8.

When the first bist mark is found, that is, when the content of the temporary register Y is zero, the system / servo microcomputer 15 proceeds to the stop mode and then turns off the power to the initial state of the scheduled recording (step S12).

However, in the zero-stop recording mode using the counter, when the recording is completed, the user can not perform the eject key because of the user's carelessness. The tape is ejected from the set and the counter is counted to zero. Therefore, when the eject tape is reloaded and replayed, the user does not know the start of the recording.

It is an object of the present invention to provide a recording and reproducing apparatus and a recording and reproducing method of a recording and reproducing apparatus capable of automatically detecting a tape recording portion even if an eject key is depressed due to user's carelessness after completion of recording using a count zero- So that the convenience of using the system can be ensured.

In order to implement the object of the present invention in particular, the system is configured to set a tape insertion mode and a zero-stop mode in recording, and to check whether there is a recording key input. If there is a recording key input, Storing a count value which has been performed up to the present time when ejecting a tape when there is an eject key input by the user; and performing a rewind operation by a zero-stop count value stored at the time of re-insertion of the eject tape, : 00 in a Vishal system, and a zero-stop storage processing program having a series of processes for reproducing operation.

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

FIG. 3 shows a Vishill system having an automatic control function for correcting positional restoring at zero-stop according to the present invention.

Here, the supply reel SR and the reel reel (TR) accommodating the cassette tape margin (CST) mounted on the set are provided. When these reel (SR) and reel (TR) The remaining time is calculated with reference to the tape thickness information, the tape speed information and the reel rotation speed difference set by the tape remaining amount change switch and the standard / 3 times switch, and the remaining time is displayed by the digitron 24 A control pulse circuit (not shown) for processing the control pulses detected from the microcomputer 21, the digitron 24 for displaying the remaining time or the like, and the control / 23, a digitron 24, and the like.

The microcomputer 21 and the like are provided with a zero-stop storage processing program 100 as shown in Fig.

Here, the system checks whether there is tape insertion at the time of recording (Step 1010). If there is a tape insertion, the OSD counter selection menu is displayed (Step 102), and the digitron value displays 00:00 of user setting (Step 103) .

Then, it is checked whether the recording key is turned on (step 104). If there is a recording key input, recording progress and counting operation are performed until recording is ended (step 105).

Then, it is checked whether or not there is an eject key input by the user (step 107). When there is an eject key input, the count value stored up to the present time at the time of tape ejection is stored (step 108) (Step 110), it is checked whether there is a reset key input of the subject (step 111), and if so, the digitron value is displayed as 00:00 (step 112) , And a reproducing operation is performed (step 113).

3, when the user performs a recording operation using the zero-stop function by the counter, the microcomputer 21 performs a reel rotation (rotation) from the supply reel SR and the take- Calculates the recording time at the time of recording based on the tape thickness information of the user setting and the tape speed information, and calculates the remaining time at the time of reproduction.

At this time, the microcomputer 21 stores the counter zero-stop point 00:00:00 before performing the recording operation, and counts the recording time based on this point.

When the microcomputer 21 performs the zero-stop function and the recording is completed and the eject key is depressed by the user, the microcomputer 21 stores the time data thus far stored in the memory at the same time when the tape is ejected.

Thereafter, when the user realizes that he / she is careless and reinserts the eject tape, the tape is rewound by the time value already stored and the playback operation is performed.

The above operation is performed together with the zero-stop storage processing program 100 of FIG. 4 in that the system checks whether a tape is inserted at the time of recording, displays an OSD counter selection menu if there is a tape insertion, The tron value indicates 00:00 of the user setting (steps 101 to 103).

Then, if there is a recording key input, recording progress and count operation are performed until the recording is ended, and the recording is terminated (steps 104 to 106).

If there is an eject key input, it is checked whether or not there is a re-insertion of the eject tape. If the eject key is re-inserted, the rewind operation is performed by the stored zero-stop count value And checks whether there is a reset key input by the user. If so, the digitron value is displayed as 00:00, and the reproduction operation proceeds (steps 107 to 113).

In the present invention, even if there is an eject key depression due to user carelessness after the user completes the recording operation using the zero stop function by the counter, the count value advanced until then can be stored and the reproduction operation can be performed from the zero stop point And the reliability of the use of such a system can be securely secured.
