Abstract

PURPOSE:To improve user's operability by providing an input means for specifying a recording order, a means for arithmetically operating the moving quantity of a medium and a means for storing the arithmetically operated result and sequentially controlling reserved recording based on the arithmetically operated result which is stored. CONSTITUTION:The arithmetic means 25 performs arithmetic processing in accordance with a specified algorithm by receiving output from the input means 21 and a storage means 22. Though it is a program A that is recorded first, the recording order on a magnetic tape T is specified like a figure, so that a time which is earlier by the length Tc of the broadcasting time of a program C, that means, t0-Tc is outputted as a video recording start time. When output from a timer 23 coincides with the arithmetically operated result t0-Tc, a sequence control means 24 outputs a video recording command and outputs a stopping command at a time t1. Based on the relation between the current position of the tape T and a next video recording start position, the moving quantity of the tape is controlled and the recording of a program B which should be recorded next is performed in advance of the obtained position. Thus, the tape needs not be moved.

It is a sequence control means that outputs operation mode command signals such as recording and stoppage to the electrical circuit. Incidentally, in reality, all of the above-mentioned means shown in FIG. 5 are built into the microcomputer. Next, the operation of the above configuration will be explained with reference to the time chart shown in FIG. 6 and the recorded contents on the magnetic tape shown in FIG. 7. FIG. 6(a) shows the VTR operator using the operation panel (20)
This is the reservation details entered via . That is, time (t
(A) is the program from o) to (t1), (B) is the program from time (t2) to (t3), and (B) is the program from time (t4) to (t4).
The program up to 5) is designated as (C), and the program from time (t6) to (t7) is designated as (D), and these reserved contents are stored in the storage means (22) via the input means (21) in Fig. 5. It has been done. In addition, information on each program (A) to (rJ) is provided on TV.
It is handled in the form of a broadcast channel number. FIG. 6(b) shows the operation of the VTR in scheduled recording mode. That is, the sequence control means (2
0 selects the program (A) as a signal to be recorded at time (to) from the outputs of the mesmerizing means (22) and the timer (23) and outputs a recording command, and the VTR starts recording (
(hereinafter referred to as REC). Then, the sequence control means (20
outputs a stop command. The VTR stops recording and issues a stop sign S (
(hereinafter referred to as STOP). Next, time (t2
), the sequence control means (20 indicates program CB) is selected as a signal to be recorded, and a recording command is output again, and a stop command is output at time (t4). Thereafter, similar operations are repeated until time (t7) to complete the reserved operation. Note that when the VTR is stopped in the scheduled recording mode, the recording means (22). MIW4 is configured to be turned off except for parts that must continue to operate, such as the timer (23) and sequence control means (20). Figure 7 shows the time (t7), that is, when the reservation content is fulfilled. This shows the recorded content on the magnetic tape (↑) at the time when each program (A) to (D) was recorded on 11'i#i, which was reserved from the beginning of the FM tape (↑). [Problems to be Solved by the Invention] Since the conventional recording/reproducing device is configured as described above, programs can be broadcast regardless of the recording order on the tape-shaped recording medium desired by the operator. For example, when an operator performs a reservation operation, there is a possibility that the recorded content will be saved for a long time.
:)． (A). (D). If the order is (B), that is, among the four programs, program (C) has the possibility of being stored for the longest time, and program (B) has the possibility of being deleted earliest. In such cases, considering the efficiency and convenience of using tape-shaped recording media, program (C)
．． (A). (D). It is desirable to record in the order of (B). This recording order makes the recorded contents of program (B) unnecessary and is very convenient when recording another program (E) in that part. When using tape, program (B) and a different number m
Compare the length of time in (E) and take your turn! ! It was necessary to make sure that the I (E) time was short, which led to problems such as poor usability and unnecessary recorded content remaining. The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a recording/playback device that can record a plurality of programs on a recording medium in an arbitrarily specified order during reservation recording. With the goal. [:Means for Solving Problem 1 1 The recording and reproducing apparatus according to the present invention determines at least the recording start time and recording end time of each program from the reservation contents including the recording order on the tape-shaped recording medium at the time of completion of reservation recording. The present invention is characterized in that it has a means for calculating the amount of movement of the tape-shaped recording medium, and is configured to perform sequence control of the scheduled recording state based on the calculation result.

do. FIG. 1 is a block diagram showing a schematic structure of a portion related to scheduled recording in a VTR according to an embodiment of the present invention. Since they are the same, they will be given the same reference numerals and detailed explanations will be omitted. In FIG. 1, reference numeral (25) denotes an arithmetic means, which receives the outputs of the input means (2l) and the storage means (22) and performs arithmetic processing according to a predetermined algorithm. Further, the sequence control means (20 is a storage means (22)

It is configured to output an operation mode command signal such as RE (hereinafter referred to as RE). In addition, in reality, each means (2l) to (25) in FIG.
are all built into the microcomputer. Next, the operation of the above structure will be explained with reference to the flowchart shown in FIG. 2, the time chart shown in FIG. 3, and the recording pattern on the magnetic tape shown in FIG. 4. The flowchart shown in FIG.
2) is a control operation performed by the calculation means (25), the timer (23), and the sequence control means (24). Figure 3 (0 is the reservation content entered by the VTR operator, and the programs (A) to (D) to be recorded are shown in Figure 6 (a).
This is the same as the case of the conventional example shown in , and in addition to such reservation contents, it is possible to input the recording order of the program on the magnetic tape (T) at the time of completion of reserved recording. The order shown in Figure 4, namely (C).
(A). (D). They are input so that they are arranged in the order of (B). In addition, (Ta), (↑b), (Tc) in Figure 3 (a)
, (Td) are for each program (A), (B) . (C
)． This is the broadcast time length of (D). Once the scheduled recording status is set, in step (1l) of the flowchart shown in FIG.
The first recording start time is calculated. This step (1l
), the recording start time is derived according to an algorithm that secures an area for future recording by advance recording, that is, by advancing the recording start time. For example, in the case of Figure 3, the program to be recorded first is &All (A), but the recording order on the magnetic tape (T) is specified as shown in Figure 4, so the program (C
), which is earlier by the broadcast time length (Tc), that is, ( t
o-Tc) is output as the recording start time. next,
In step (12), the receiving channel of the VTR is tuned to that of program (A). In step (l3), when the output of the timer (0) matches the calculation result (to-Tc) in step (11), the sequence control means (24) outputs a recording command.Subsequently, in step ( l4), the sequence control means (24) issues a stop command at time (tt). That is, V
As shown in FIG. 3(b), TR is the time (to-Tc
) to (t1). Continuing, when it is determined No in step (15), step (16)
Proceed to. Here, the amount of movement of the magnetic tape is controlled based on the relationship between the current position of the magnetic tape and the next recording start position. 1 in Figure 4 1.1 2. n3, fL4 indicates the position of the magnetic tape, and the position at time (11) is 11, and the recording of the program (B) to be recorded next can be pre-recorded from here. Therefore, the position of the magnetic tape is 11. It turns out that no movement is necessary. Next, the program returns to step (l1) and calculates the recording start time of program (B). In this case, as is clear from FIGS. 3 and 4, the recording start time of program (B) is earlier than the recording start time of program (D) by the broadcast time length (d), that is, (t2-Td). This is output as the start time. Hereinafter, the operations up to step (l5) are the same as in program (A). In step (18), the current position of the magnetic tape is 14, as shown in FIG.
Since the starting position of 5l1 is cross O, the magnetic tape is lengthened (3
1 4-1 0) is RE. At this time, the sequence control means (24) outputs the RE command signal and counts the number of CTL signals. Here, the CTL signal is one frame (33m) of the video signal.
s) is recorded by a fixed magnetic head on the lower end of the magnetic tape, and is used to control the running of the magnetic tape during playback, and is used to detect the amount of movement during FF and RE. In other words, the movement of the CTL signal by N times is (
33XN) ms. Therefore, when the count value of CTL reaches the length of the magnetic tape (see ← 10), that is, when the recording time reaches (cho a + ↑ b ◆ ↑ c + Td), the sequence control means (20) is activated. A stop signal is output and the magnetic tape comes to a halt.The time required for RE is shown in Figure 3 (b).
), it is (Tr). Recording of the program CG) starts at time (t4) from the magnetic tape viewing position 0 set by the above RE operation, and starts at time (t4).
The process ends at t5). After that, in step (l8), FF is performed for the length (2 points, 1 point). The amount of movement at this time is detected using the CTL as well as in the case of RE described above.
This is done by counting . In addition, the time required for FF is (Tf), as shown in FIG. 3(b),
The position of the magnetic tape at the end of this FF is 2. Recording of program (D) starts at time (t6), and starts at time (t6).
The process ends at t7). As described above, the reserved programs (A), (B).
(C). As shown in Figure 4, all of (D) are recorded according to the desired state of the magnetic tape, and step (D) is recorded according to the desired state of the magnetic tape.
If YES is determined in l5). Ends the specified scheduled recording. Note that in the above embodiment, the REC during the reserved recording period is
．． RE. Operations other than the FF operation are simply described as STOP, but similarly to the conventional example, during this stop period, the storage means (22), calculation means (25), timer (23), sequence control means (
The configuration may be such that the power is turned off to parts other than those that must continue to operate, such as 20. Further, in order to reliably record the reserved program without any omissions, the calculation means in the embodiment may record the preceding and following portions of the recorded program for a short period of time. Furthermore, at the end of the reservation input, the calculation means (2
In step 5), we will determine whether or not the reservation details can be realized, and if it is not possible,
Usability can be further improved by configuring the system so that this information is communicated to the operator using the display on the operation panel or the TV screen. Furthermore, in the above embodiment, it has been explained that all of the means shown in FIG. 1 are built into the microcomputer, but the invention is not limited to this as long as it realizes similar functions. Even if it is configured with general-purpose ICs,
The same effect as the above embodiment is achieved. Furthermore, although the above embodiment has been described for the case of a VTR, the same effect will be obtained even if it is applied to any recording/reproducing system using a tape-shaped recording medium such as a DAT. [Effects of the Invention] As described above, according to the present invention, it is possible to specify the recording order on the tape-shaped recording medium at the time of completion of reservation recording, and during the reservation recording period, the advance recording start and the Since the tape-shaped recording medium can be rewound and fast-forwarded, the recording order on the recording medium can be set as desired by the operator.
This has the effect of making effective use of the recording medium and providing an easy-to-use recording/playback device.
