Description

V-Plus Recording method

The present invention relates to a processing means capable of automatically returning to a starting point of a tape after completion of reserved recording in a video cassette recorder (hereinafter referred to as a VCR) system, and in particular, when reserved contents in a V- So that the tape can be returned to the reservation start point.

The VCR (Video Cassette Recorder) has a program schedule recording function that automatically records the program program time if it is reserved through a timer, a G code system, a V + system, or the like.

In addition, the VISIAL system has a VISS (VISS: VHS INDEX SEARCH SYSTEM) function for recording the position information of the tape at the time of recording of the tape. It records a certain signal when recording a video tape, So that the user can perform a quick search for the first portion of the recorded program.

However, in the conventional VISCAR system, it is troublesome to rewind to see the recorded program after the reserved recording is completed, and to find the beginning of the reserved recording.

This is because the vial system is automatically turned off after the scheduled recording is completed, so that the user can not return to the first recording portion before the user selects the rewind mode. In this case, when the rewind mode is automatically performed, It was only possible when the tape ran to the end.

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

Here, 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 microprocessor 10 includes key signals Detects a key input signal transmitted from a certain key by scanning, and transmits the key data to the system controller / servo microprocessor 15 in series.

The program recording time, the end time, the desired broadcast channel, and the like input by the user through the key metrics unit 7 are recorded in the timer microprocessor 10. In general, such a program reservation recording setup may include a plurality of different programs You can make reservations.

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

In addition, the signal corresponding to the mode decoded by the control / microprocessor 15 is serially supplied to the timer microprocessor 10 so that the timer microprocessor 10 can display various modes have.

The control signal recording section 3 provides a control signal for outputting the 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 microprocessor 15, the control head 9 provides the bismark signal to cause the bismark to be recorded at the beginning of the tape that is scheduled to be recorded.

On the other hand, the SISCON / servo microprocessor 15 receiving the signal indicating the scheduled recording completion time from the timer microprocessor 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 / servo microprocessor 15, and the control / microprocessor 15 judges that the tape is the recording start portion according to the signal and stops the deck unit State (stop mode).

FIG. 2 shows an automatic rewinding method after a specific program scheduled recording in the conventional system as described above.

Here, in a state in which the timer microprocessor 10 has confirmed that it is the current program schedule recording mode, the recording start time is continuously checked (steps S1 and S2). When the timer microprocessor 10 transmits the key data related to the recording to the system / servo microprocessor 15 when the recording start time is reached, the system / servo microprocessor 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 microprocessor 10 continuously checks the recording end time and notifies the state of the recording to the system controller / servo microprocessor 15 at the end of the recording time so that the system microprocessor / 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 microprocessor 10 judges that there is no more scheduled program to be recorded thereafter and causes the SysCon / Servo microprocessor 15 to perform the rewind mode, and therefore, under the control of the SysCon / Servo microprocessor 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 system / servo microprocessor 15, and when the system / servo microprocessor 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 SysCon / Servo microprocessor 15 compares the number of reserved programs with the number of detected bist marks to find the first bist mark, Repeat from S8.

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

In this case, when a plurality of reserved recordings are made on one tape, the automatic rewind mode is performed after the reserved recording program is conventionally performed. However, when a plurality of reserved recordings are made on one tape, In order to view the program, there is still an inconvenience that the user has to search for the program by the number manipulation. On the other hand, when the user views a specific program regardless of the scheduled recording, the position of the tape is changed And the like.

In the above-described system, when the user performs the scheduled recording by the timer reservation function, the function can be performed. However, since the reserved recording system using the broadcast information such as V + PLUS is not provided with the circuit such as the VPLUS decoder, There was a problem with.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the above-described problems of the prior art, and it is an object of the present invention to provide a system and method for recording a program, It is possible to automatically rewind the tape position to the starting point of the last scheduled recording program even if the reproducing operation is performed using the predetermined tape.

In order to realize the object of the present invention, the system may include a step of determining whether the microprocessor performs scheduled recording after performing the scheduled recording mode, performing a rewind mode to the starting point of scheduled recording if the scheduled recording is terminated, If it is judged that there is another reserved recording when the start point of the reserved recording at the time of the reserved recording is reached, fast sending is performed again to the reserved recording end point and if there is no other scheduled recording, The process is returned to the processing step of judging whether there is another reserved recording in the case of the stop mode or not.

DESCRIPTION OF THE REFERENCE NUMERALS

100: Recording time return processing program

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

Figure 3 shows a system circuit block diagram related to the present invention.

Here, a tuner circuit 12 to which a broadcast signal receiving antenna 11 is connected, a video recording circuit 15 for recording a video signal selected by the tuner circuit 12 on a video tape, and a tuner circuit 12 A video decoder 14 for extracting various types of video data inserted in a blanking period in a video signal provided from the video signal provided to the microprocessor 13, An SDI circuit 22, a monitor 23, and the like.

In addition, the system is provided with a recording-point-in-time recovery processing program 100 shown in FIG.

Here, the system microprocessor 13 determines whether or not the scheduled recording is ended after performing the scheduled recording mode (steps 101 and 102). If the scheduled recording ends, the system microprocessor 13 performs the rewind mode to the starting point of the scheduled recording (step 103).

If it is determined that there is another reserved recording (step 104), it is determined whether there is a new recording mode. If it is determined that there is no other reserved recording, (Steps 105, 106, 107).

In the playback mode, a play operation is performed (step 108), and then a stop mode is determined (step 109). In the stop mode, a process is performed to determine whether there is another scheduled recording.

In the present invention, when the user makes a V-plus recording reservation through the OSD circuit 12 using a remote control transmitter or the like, the microprocessor 13 stores the channel and time set by the user in the reserved memory 21 ).

When the broadcast signal received through the antenna 11 and the tuner circuit 12 is decoded by the CABIS decoder 14 and then transmitted to the microprocessor 13, the microprocessor 13 If the reserved content of the user stored in the reserved memory 21 is checked and the user is a reserved channel, the predetermined program is recorded together with the VisMark through the video recording circuit 15.

When the recording of the specific program is completed through the above process, the microprocessor 13 reverts the deck to the rewind mode and returns the tape to the reservation start point where the bismark is inserted.

At this time, if the user performs the reproducing operation in the time zone other than the scheduled recording time, the reproducing operation is performed. If there is another scheduled recording, the microprocessor 13 drives the deck to the reserved recording end point If the program is operated in the fast-forward operation and another scheduled recording program is finished recording, the program will be returned to the scheduled recording start point.

The above operation is performed by the microprocessor 13 together with the recording-point return processing program 100 shown in FIG. 4. This is because the system microprocessor 13 performs the reserved recording mode, If it is determined that the reservation recording has been completed, a rewinding mode is performed to the starting point of the reserved recording (steps 101 to 103).

If it is determined that there is another reserved recording, it is determined whether there is another reserved recording. If there is no reserved recording, it is determined whether the reserved recording is in the reproducing mode (step 104 ~ 107).

If it is in the playback mode, the playback operation proceeds, and then the stop mode is determined, and if it is the stop mode, the process goes to the processing step to determine whether there is another scheduled recording (steps 108 and 109).

As described above, according to the present invention, when the reserved recording of the viral system is completed, the tape is automatically returned to the reserved recording start point, so that the user can relieve the trouble of running the tape until the start of the reserved recording program. The convenience of using such a system can be securely secured.
