The present invention relates to a method of playing a continuously recorded VTR tape, in particular, when a user inputs a specific day to watch a program of a specific date on a tape in which a program is continuously recorded at the same time every day, the program is automatically recorded. After moving to the tape position, playback is performed. After the playback operation is finished, the tape position is moved to the last recorded end position, thereby increasing the convenience of use and immediately recording the next program sequentially. Therefore, the present invention relates to a method of reproducing a continuously recorded VTR tape in which the system functionality is improved accordingly.

In general, as shown in FIG. 1, the VTR system includes a head 70 for recording or reproducing an input digital signal on a video tape, and a signal amplification for amplifying information signals input and output to the head 70. A section 71, a channel coding section 72 for inputting a channel coded signal to the signal amplifying section 71, and an A / D converter for converting an analog signal input to the channel coding section 72 into a digital signal. It consists of (73).

The video signal processor 74 is connected to one end of the A / D converter 73, and the video output device 75 is connected to one end of the video signal processor 74. 75 is connected to a display 76.

In addition, one end of the video signal processor 74 is connected to a tuner circuit 77 for receiving a video signal of a TV and processing a broadcast signal.

The video signal processor 74 is connected to a microcomputer 78 for controlling overall operation of the system. One end of the microcomputer 78 is connected to a keyboard 79 for setting a function setting signal of a user. The rotary transformer 80 is connected between the head 70 and the signal amplifier 71.

On the other hand, referring to the operation of the conventional VCR system having the above configuration, first, when the user wants to continuously record on the tape a program that is continuously broadcasted every day at a predetermined time, such as extra-curricular broadcasting of TV recording through the keyboard 79 When the function is set, the microcomputer 78 recognizes this and executes the recording function.

That is, the broadcast signal is tuned through the tuner circuit unit 77 and input to the video signal processor 74. In addition, the image output unit 75 processes the image signal of the input tuner circuit unit 77 into an A / D converter 73 by processing the image signal, and accordingly, an analog form is input from the A / D converter 73. The information signal is converted into a digital signal.

In addition, the digital signal converted by this A / D converter 73 is signal-processed via the channel coding unit 72 and then input to the signal amplifying unit 71. Then, the digital signal inputted by the signal amplifier 71 is signal-processed via the channel coding unit 72 and then input to the signal amplifier 71. Then, the signal amplification unit 71 amplifies the input digital signal to a predetermined level and is transmitted to the head 70 through the rotary transformer 80. Accordingly, the head 70 records the program on the tape. .

When the user wants to play a program of a specific date, the user looks at the screen of the display 76 and selects a specific date using the keyboard 79 and proceeds to another mode to check the program recorded on the specific date. Will be done.

In addition, when recording a program on the tape continuously, the end position of the recording program on the tape is moved, and then the program is recorded.

However, the function control method of the conventional VCR system having the above-described configuration, when the user checks the program of a specific date or sequentially records the next program, the user sequentially views the keyboard 79 while watching the screen on the display 76. Since the function setting operation must be executed by switching the switching mode, the function setting time is considerably time-consuming, and the user needs to repeatedly execute the function setting operation by using the keyboard 79. There was a problem to be increased.

Therefore, the present invention is invented to solve the above problems, the program is automatically recorded when the user inputs a specific day to watch a program of a specific date on the tape continuously recorded in the same time zone every day After moving to the position of the recorded tape, the playback operation is performed. After the playback operation is finished, the user can move the tape position to the last recorded end position so that the user can move to the end position recorded on the specific date. There is no need for a separate cumbersome operation to search for recorded programs, which increases the convenience of use and allows the next program to be recorded immediately and sequentially, thus improving the functionality of the system. It is an object of the present invention to provide a method for reproducing a VTR tape.

In order to achieve the above object, the present invention initializes each buffer and the current position non-counter by setting the continuous recording mode on the inserted tape, and stores the recording time interval, and determines whether the current time is a reserved recording time. A recording time recording process for recording a program on a tape with a vis signal for a predetermined time for each consecutive date if the current time is determined to be a scheduled recording time, as determined by the recording time judgment process and the reservation recording time judgment process; In the reservation recording program recording process, after performing reservation recording for a set time for each consecutive date, a desired date input judgment process for judging whether a desired date for playback is entered in the recorded tape, and the result judged in this desired date input judgment process If it is determined that the desired date is entered, Tape position determination process to judge the difference between the date and the subtracted input date, and if the tape position determination process judges that the current tape position matches the input date, the tape is decremented at the current position A first reproducing operation of inputting a tape date into a buffer and reproducing the contents recorded on the date for a predetermined time; and as a result of judging from the tape position determining process, if it is determined that the current tape position does not match the input date An input date judgment process for determining whether the current tape position is greater than the input date, and if it is determined that the input date is greater than the current position of the current tape, the rewind operation and service are performed according to the changed date. Decrease the counter by the shifted date and enter the current tape position into the buffer And a second rewinding operation for reproducing the contents recorded in the recording data, and if it is determined that the input date is not greater than the position date of the current tape as a result of the input date determination process, the fast forwarding and rewinding operation is performed. A third playback operation for inputting the current tape position into the buffer after the increase by the changed date, and reproducing the contents recorded on the date; and a tape recorded for that date in the first, second, and third playback operations. It is characterized by consisting of a process of moving the final recording position, which plays back by the amount and moves the position of the tape to the position of the last recorded program.

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

The apparatus to which the present invention is applied includes a head 1 for recording or reproducing an input digital signal on a video tape and amplifying information signals input and output to the head 1, as shown in FIG. A signal amplifier 2, a channel coder 3 for inputting a channel coded signal to the signal amplifier 2, and an A / A for converting an analog signal input to the channel coder 3 into a digital signal D converter (4).

The video signal processor 5 is connected to one end of the A / D converter 4, and the video output device 6 is connected to one end of the video signal processor 5. The display 7 is connected to 6.

In addition, a tuner circuit 7 for receiving a video signal of a TV and processing a broadcast signal is connected to one end of the video signal processor 5.

The video signal processor 5 is connected with a microcomputer 9 for controlling overall operation of the system, and one end of the microcomputer 9 is connected with a keyboard 10 for setting a function setting signal of the user. The rotary transformer 11 is connected between the head 1 and the signal amplifier 2.

In addition, the microcomputer 9 includes a first buffer 12 for storing the first date recorded on the tape, a second buffer 13 for storing the current date, and a third buffer for storing the last date recorded on the tape. 14 and a fourth buffer 15 for storing the date set by the user, and the microcomputer 9 also includes the current position non-counter 16 and the tape of the current position non-counter counting the current position bis signal of the tape. The last position non-counter 17 that counts the last position BIS signal, the program period counter 18 that counts the duration of the recorded program, and the date stored in the second buffer 13 to the fourth buffer 15. A variation counter 19 is provided to counter the difference between the stored input dates.

Next, a method of the present invention applied to an apparatus having the above configuration will be described.

First, when the video tape is inserted into the deck, as shown in FIG. 3A, the microcomputer 9 proceeds from the initial step S1 to the continuous recording mode determination step S2, and continues through the keyboard 10 in the continuous recording mode. Determine if is set. If the continuous recording mode is not set as a result of the determination, the process proceeds to the general VTR function performing step S3 to perform a general VTR function, for example, a video tape playback function. However, if the continuous recording mode is set as a result of the determination in step S2, the process proceeds to the buffer and non-counter initialization execution step S4 to initialize each buffer 12-15 and the current position non-counter. Then, the set reservation cycle time is calculated and the corresponding data is input to the program period counter 18, and the reservation recording time determination step S6 is performed. Then, if the current time is determined to be the scheduled recording time, as determined by the reserved recording time determination step (S6), proceed to the recording execution operation step (S7) to execute the recording operation, and in the non-counter recording step (S7), the current recording starts with the start of the recording. The Vis counter of the position and the last position is continuously recorded on the tape, and the process proceeds to the reserved recording completion determination step (S9).

That is, the broadcast signal is tuned through the tuner signal processor 8 and input to the video signal processor 5. The video signal processor 5 processes the video signal inputted by the tuner circuit 7 to the A / D converter 4 to process the video signal. Accordingly, the A / D converter 4 has an analog form. The information signal is converted into a digital signal. In addition, the digital signal converted by this A / D converter 4 is signal-processed via the channel coding unit 3 and then input to the signal amplifier 2.

Then, this input digital signal from the signal amplifier 2 is signal-processed via the channel coding unit 3 and then input to the signal amplifier 2. Then, the signal amplification unit 2 amplifies the input digital signal to a predetermined level and is transmitted to the head 1 through the rotary transformer 11, whereby the head 1 records a program on a tape. .

The microcomputer 9 increases the current position non-counter 16 and the final position non-counter 17 by one.

On the other hand, proceeding to the reservation recording completion determination step (S9) to determine whether the reservation recording is completed, and if the reservation recording is not finished as a result of the determination continues recording operation.

If the reservation recording is ended as a result of the determination in step S9, the process proceeds to the date input determination step S10, and when the user does not input any desired date for playback, the process returns to the initial step S1 and loops. If the user repeatedly inputs the desired date for playback, the program proceeds to step S11 to determine whether a recorded program exists on a date corresponding to the current input date. If there is no recorded program on the set date, it proceeds to the warning display step (S13) and indicates that there is no program corresponding to the currently set input date.

However, if it is determined in the step S11 that the program corresponding to the input date is recorded on the tape, the process proceeds to the tape position measuring step S12 to determine the input date from the position date of the tape currently contacting the head 1. After subtracting, the value is inputted to the variable counter 19, and the flow proceeds to the variable counter determination step S14. Then, the flow counter proceeds to the determination step (S14) to determine which value the subtraction value inputted to the variable counter 19 has, and if the determination result has a value of 0, that is, the date of the tape located in the head and the currently set If it is determined that the input date is the same, it moves to the program front end movement step (S15). Then, in the program front end movement step (S15), the playback position of the current program is moved to the position where the current position non-counter 16 is reduced to -1, and the playback operation step (S16) is performed. Therefore, in the reproducing operation step (S16), the reproducing operation is carried out for a predetermined program period and stored as an input date in the second buffer 13, and the process proceeds to the reproducing operation determining step (S17). If the reproducing operation is not performed for the period inputted in the program, the program reproducing operation is continuously performed. If it is determined that the reproducing operation is performed for the period inputted to the program counter, the flow advances to the reproducing operation terminating step (S18).

Therefore, in this playback operation ending step (S18), the playback operation of the recorded program is ended, and the recording position shifting step (S19) is performed to move the current tape to the final position of the recorded program on the last date and to determine the reserved recording time. Returning to step S6, the loop is repeated.

On the other hand, if it is determined that the date of the tape located in the head and the currently set input date is not the same as the result of the determination in the variable counter determination step (S14), the flow proceeds to the variable counter reduction determination step (S20), where the subtracted value is " In the case of having a value of '-', that is, the position of the tape is located before the input date, the process proceeds to the forward movement operation step S21. Therefore, in this forward movement operation step S21, the current position non-counter 16 performs a fast forward to the tape position so as to increase by the subtraction value H, and proceeds to the fast forward operation completion determination step S22. Therefore, if it is determined in the fast forward operation completion determination step (S22) that the fast forward is not performed as much as the subtracted value (H), the fast forward is continuously performed, and as a result, the fast forward operation by the subtracted value (H) is determined. If it is determined that this is performed, the current position of the tape position is increased as the input date in the second buffer 13 after increasing by the subtraction value H to the current position non-counter 16, and the process returns to the playback operation step S16 and loops. Run

On the other hand, if it is determined in the variable counter reduction determination step (S20) that the subtracted value (H) is not a "-" value, that is, if the position of the tape is located behind the input date backward movement operation step The process proceeds to S23. Then, in this backward movement step (S23), the current position non-counter 16 is added by the subtraction value (H) to rewind the position of the tape (REW), and the result of the determination in the rewind operation completion determination step (S24). If it is determined that the rewinding is not performed as much as (H), the rewinding is continuously performed. If it is determined that the rewinding operation is performed as much as the subtraction value H, the current tape is reduced to the current position non-counter 16 after it is determined. The position date is stored in the second buffer 13 as the input date, and the process returns to the reproducing operation step S16 to execute a loop.

As described above, according to the present invention, when a user inputs a specific day to watch a program of a specific date from a tape continuously recorded at the same time every day, the program automatically moves to the position of the tape where the program is recorded. After the playback operation is completed, the position of the tape is moved to the last recorded end position, thereby increasing the convenience of use, and immediately recording the next program sequentially, thereby improving the system possibility. It is effective.
