Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a reproducing unit for reproducing a recording signal recorded on a recording medium starting from a recording medium start position and a recording start time of the recording medium by at least one reproducing head, Positioning means for positioning the at least one reproduction head at the desired recording medium position for reproducing a recording signal.

An apparatus of the kind described above is described in the specification of US Pat. No. 5,661,847 A and comprises a video recorder. The known video recorder can record one or a plurality of broadcast recording signals from a recording medium start position on a magnetic tape and a recording start point on an inclined recording track of the magnetic tape in a recording mode. Here, the recording medium start position indicates a position on the magnetic tape at which a recording signal starts to be recorded, and the recording start time is an actual time at which a signal to be recorded starts to be recorded.

[0003] Known video recorders include an index signal generator to define an index signal in a linear recording track of magnetic tape at the beginning of each broadcast of a recording session. The index signal is a so-called VISS (Video Index Searc
h System) signal. VPS (Video Program System) detectors are designed to detect VPS signals that belong to and identify each broadcast. Each time the VPS detector detects a change in the VPS signal indicating the start of a new broadcast, a control signal is provided to an index signal generator to generate and record a VISS signal.

[0004] The known video recorder further comprises a reproducing means comprising two magnetic heads.
These magnetic heads are fixed to the head disk of the scanner and can be driven to rotate. In a reproduction mode of the video recorder, a recording signal specified on a magnetic tape as a reproduction head can be reproduced.

[0005] Known video recorders further comprise positioning means including remote control and a magnetic tape drive. In the playback mode of the video recorder, an index search signal can be supplied to the video recorder from a remote control in order to position the magnetic head at a desired recording medium position where a recording signal of a certain broadcast starts. Such an index search signal may include information for, for example, counting from the current recording medium position, such that a third recorded broadcast on the magnetic tape is reproduced toward the end of the magnetic tape. it can. When this index search signal is received by a known video recorder, the magnetic tape transport apparatus moves the magnetic tape toward the end of the magnetic tape at several times the reproduction speed until the index signal is detected three times. Drive the tape. When the desired recording medium position is reached, the recording signal is reproduced by the reproducing means at a normal reproducing speed. This process is known as an index search mode. In this way, the magnetic head is immediately positioned at the desired recording medium position where the recorded broadcast starts.

However, for known video recorders, it has been found that the recording medium position at which the magnetic head is positioned by the positioning means depends on the actual recording medium position at the moment when the index search signal is received. For example, recording signals of seven broadcasts are recorded on a magnetic tape, the start of each broadcast is specified by an index signal, and an index for positioning the magnetic head at the start position of the third broadcast toward the end of the tape When the search signal is given by remote control, the positioning means can set the magnetic head at the recording medium position where the third, fourth, fifth, sixth or seventh recorded broadcast starts.

At the time of receiving the index search signal, for example, the position of the actual recording medium is set such that the recording signal of the second recorded broadcast on the magnetic tape counted from the beginning of the magnetic tape can be immediately reproduced. When the index search signal is given, the magnetic tape device drives the magnetic tape and reproduces the fifth broadcast recording signal recorded on the magnetic tape by the reproducing means.

On the other hand, for example, when the actual recording medium position is at a position where the broadcast recording signal recorded on the magnetic tape fourth from the beginning of the magnetic tape can be immediately reproduced, Is supplied, the magnetic tape drive drives the magnetic tape, and the reproducing means reproduces the recording signal of the seventh broadcast recorded on the magnetic tape. Thus, known video recorders have the disadvantage that the magnetic head cannot be positioned at the desired recording medium position without considering the actual current position on the recording medium.

A further disadvantage found in known video recorders is that the magnetic head is positioned at the recording medium position where the index signal was recorded only by the index search signal. In the case of a known video recorder, for example, it is impossible to immediately find a recording medium position where a recording signal of a third recorded broadcast is recorded and 15 minutes after the start of the third broadcast. It is possible.

The present invention aims at obviating the above difficulties and providing an improved device of the kind described above. For this purpose, input means for supplying reproduction time information for specifying a desired reproduction time point is provided, and the desired reproduction time point includes start time information for specifying a recording start time point and desired recording time of the recording medium. The positioning means, when determining the desired recording medium position, determines the start time information from the supplied reproduction time information, which corresponds to the sum of the elapsed recording time elapsed when recording the recording signal at the medium position. Is achieved in a device of the type described above which is designed to subtract In the apparatus according to claim 1, it is possible to position the magnetic head at a desired recording medium position irrespective of a current recording medium position through input of start time information and reproduction time information, and thereafter, a recording signal is transmitted to the desired recording medium position. It is advantageous to be able to reproduce from the recording medium position. To achieve this, the programmed period determined by subtracting the start time information from the play time information by the positioning means,
For example, it can be compared with the actual (current) reproduction elapsed time which is determined by the tape counter and specifies the current recording medium position of the magnetic tape. Thereafter, the positioning means is designed to rotate the magnetic tape at several times the reproduction speed until the desired recording medium position is reached. Here, if the recording medium start position is defined at the beginning of the magnetic tape, the required programmed period corresponds to the required actual reproduction period.

It has been found to be advantageous to take the measures as claimed in claim 2 in a device according to claim 1. Therefore, since the start time information can be determined from the recorded signal to be reproduced by the apparatus according to the present invention, the user of the apparatus does not need to input the start time information to specify the recording start time of the recorded signal.

Here, the desired reproduction time GT is the sum of the start time information BZI that specifies the recording start time T1 and the recording time VD that has elapsed when recording the signal AS at the desired recording medium position GT on the magnetic tape 5. Matches. The reproduction time information WZI provided by the reproduction time point button 33 is supplied to the remote control receiver 28 in the form of an infrared signal, from which it is supplied to the control unit 21. When determining the desired recording medium position GP, the control unit 21 of the positioning means 27 supplies the supplied reproduction time information WZI
Is designed to subtract the start time information BZI from. This is described in more detail below.

Here, the operation of the video recorder 1 will be described in detail with reference to the first embodiment and FIGS. 2, 3 and 4. FIG. 2 shows a part of one page from the program magazine 34 on August 12, 1998. This page of program magazine 34 was broadcast on ORF1 on August 12, 1998.
Shows a start time, a view code, and a title of a program broadcast by the broadcast station ORF1 arriving in the form of an input signal ES. Here, for example, a program titled "Side Glance" starts at 12:30. Here, show view code "17345
Is date information DI representing the date `` 12.08.98 (August 12, 1998) '' and the start time `` 12:30
(12:30) "and the broadcast station identification information SKI" ORF1 "in a coded form. Show view codes are used to program the recording of broadcasts that are staggered in time in a video recorder.

In the first embodiment, the user of the video recorder 1 receives the input signal of the broadcast station ORF1.
Assume that the recording button 31 is operated to activate the long play recording mode of the video recorder 1 in order to record ES at 13:00. Further, the long play recording mode of the video recorder 1 does not become inactive until the elapsed time of the recording of 10 hours ends, that is, until 23:00, and the recording signals from the broadcasts S1 to S11 are recorded on the magnetic tape 5. Assume.

FIG. 3 shows a time range on the magnetic tape 5 and a recording medium position P from a recording medium position P 1, which is a start end of the magnetic tape 5, to a recording medium position P 12, which is an end of the magnetic tape 5. For each recording range of the magnetic tape 5, it indicates which broadcast S belongs to the recording signal AS recorded on the magnetic tape 5. For example, broadcast S1 (1pm from 13:00
The news up to 3:20) is recorded between the position P1 and the position P2 on the magnetic tape 5. The recording medium positions P1 to P11 specify the positions on the magnetic tape 5 where the recording signals AS of the broadcasts S1 to S11 start to be recorded.

FIG. 4 illustrates the time range and the time T on the magnetic tape in which the recording signal AS is recorded in the long play recording mode during the 10 hours from the time T1 to the time T12. The recording medium start time point T1 corresponds to 13:00 which is the actual time at which the recording of the program S1 starts. Time
T1 to T11 correspond to the start points of the programs S1 to S11 listed in the program magazine 34. For example, the input signal ES of the program S5 titled "Universe" broadcasted by the broadcasting station ORS1 at 15:35 is recorded as the recording signal AS between the recording medium position P5 and the recording medium position P6 on the magnetic tape. I have. At time T5, the program magazine 34
Corresponds to the start time 15:35 of the program S5 "Universe".

Immediately after activating the long play recording mode, the control unit 21 sets the actual time information ZI = 13: 00 supplied by the clock element 22 for this recording to the start time for specifying the recording start time T1. It is defined as information BZI, and the head position of the magnetic tape 5 is defined as a recording medium start position P1. Further, for this recording, the actual date information DI = 12.08.98 supplied by the clock element 22 is defined as the recording date information ADI, and further, the broadcasting station identification information SKI determined by the signal processing means 19 from the input signal ES. Is also specified. The start time information BZI, the recording date information ADI, and the broadcast station identification information SKI are recorded on a linear recording track of the magnetic tape 5 in accordance with the VASS standard during the entire 10-hour recording session.

Further, in the first embodiment, the video cassette including the magnetic tape 5 is used for broadcasting.
Suppose that S1 through S11 were removed from video recorder 1 after they were recorded, and were inserted back into video recorder 1, for example, three days later, on August 15, 1998. The video recorder 1 is further configured to perform an initialization routine in a manner not shown in detail in FIG. 1 immediately after the video cassette is inserted. According to the VASS standard, information recorded on the linear recording track of the magnetic tape 5 is reproduced and displayed on the display 24.
For display above, during this initialization routine, the playback mode of the video recorder 1 is activated for a short time, for example 5 seconds. Further, during the initialization routine, the actual reproduction period WD and the actual recording medium position AP are determined by the tape length counter 26 as described above.

In the first embodiment, it is assumed that the actual playback period WD1 = 0: 15 and the actual recording medium position AP1 have been determined by the tape length counter 26 of the video recorder 1. The information displayed on the display 24 after the initialization routine allows the user of the video recorder 1 to record the information on the magnetic tape of the video cassette inserted into the video recorder 1.
It can be confirmed that the broadcast S of the broadcasting station ORF1 from 13:00 on August 12, 1998 is recorded. The user of the video recorder 1 can select a broadcast S in which the user is interested from the program magazine shown in FIG.

Further, in the first embodiment, it is assumed that the user of the video recorder 1 wants to watch the program S7 titled “Titanic”. Advantageously for this purpose, the user of the video recorder 1 provides the playback time information
It is only necessary to enter the start time 17:00 indicated for the program "Titanic" as WZI, which forms the desired playback time point GT1. The control unit 21 subtracts the start time information BZI = 13: 00 that specifies the recording start time T1 from the reproduction time information WZI = 17: 00 that specifies the desired reproduction time GT1, and the programmed period VD1 = 4 : 00. Actual playback period WD1 = 1 obtained by tape length counter 26:
15 and the programmed period VD1 = 4: 00 determined as described above, the control unit 21 moves the magnetic tape 5 to position the magnetic heads 7 and 8 at the desired recording medium position GP1. It can be determined that it is necessary to drive in the end direction. At this time, the control unit 21 issues related motor control information MSI to the motor 16. The magnetic tape 5 is transported toward the end of the magnetic tape 5 at a speed several times the reproduction speed. When the control unit 21 detects that the actual playback period WD, which continues to be monitored by the tape length counter 26 during the driving movement of the magnetic tape 5, coincides with the programmed period VD1 = 4: 00, this reaches the recording medium position GP1. The control unit activates the long play playback mode of the video recorder 1 and displays the recorded program “Titanic”.

In this way, it is advantageous that the magnetic heads 7 and 8 are positioned at the desired recording medium position GP1 selected at will of the user of the video recorder 1, and then the selected program S7 is displayed. is there. To this end, all users of the video recorder 1 need only enter the start time of the selected program S7 indicated in the program magazine 34, without having to consider the current recording medium position AP1 of the magnetic tape 5.

Further, in the first embodiment of the video recorder 1, the start time information BZI is determined from the recorded signal to be reproduced, so that the user of the video recorder 1
It is advantageous that there is no need to enter.

A particular advantage is that the linear recording tracks of the magnetic tape 5 are used as storage means for storing the start time information BZI and other information, so that the video recorder 1 does not require a separate storage means. That is. Further, the cassette containing the magnetic tape 5 can be inserted into another video recorder according to the present invention, and the information recorded on the linear recording track is used to position the magnetic head at a desired recording medium position GP. Advantageously, it can also be used in video recorders.

In particular, since the data rate that can be recorded on a linear recording track is sufficiently high, the above information can be recorded on a linear recording track of a magnetic tape in accordance with the VASS standard. It is advantageous that substantially no additional hardware is required.

It should be further noted that in a digital video recorder in which the measures of claim 1 for recording a signal according to the DVHS standard are taken, it is advantageous to record the above-mentioned information in a sub-code of the recording signal.

Advantageously, the video recorder 1 always has the recording medium start position at the beginning of the magnetic tape 5.
Since P1 is defined, there is no need to record the recording medium start position P1 in the video recorder 1, and it is not necessary for the user of the video recorder 1 to input it. In addition, such a rule makes it possible to record a program over the entire magnetic tape 5.

It should be noted, however, that several recording medium start positions are possible when performing several recordings on one magnetic tape, as desired recording medium start positions are possible. In this case, the recording medium position can be clearly specified through the input of the reproduction time information and the reproduction date information, and the magnetic head can be positioned at the recording medium position.
For example, a video recorder should be set to record signals every day from 20:15 to 22:15, and when it reaches the end of the magnetic tape, rewind to the beginning of the magnetic tape and overwrite the previous signal and record again. Can be. The recorded program can be reproduced by the video recorder through input of reproduction time information WZI = 20: 15 and recording date ADI corresponding to a desired broadcast.

The solution according to the invention is a so-called Time Lapse Recorder designed to record a plurality of single pictures over a very long recording time.
Note that this is particularly advantageous in

It should also be noted that the user of the video recorder 1 according to the first embodiment can input the show view code “17845” of the broadcast S7 titled “Titanic” as numerical code information. The control unit 21 derives reproduction time information WZI = 17: 00 from the input show view code, and transports the magnetic tape 5 to a desired recording medium position GPI.

When the desired reproduction time information is input in the form of a show view code, the video recorder 1 converts the date information DI present in the show view code specifying the recording date of the signal AS into an initialization routine. It should be noted that when compared with the recording date information ADI of the recording determined in the meantime, if the two date information do not match, it can be designed that certain information can be displayed on the display of the video recorder 1. .

In the second embodiment, the user of the video recorder 1 wants to watch the broadcast S11 titled “East of Eden” after finishing a part of the broadcast S7 at the actual recording medium time AP2. And Since the user has only one hour and has seen the first part of broadcast S11 before, he has decided to watch only the last hour of broadcast S11. The user acknowledges that based on the program magazine 34, the broadcast S11 has ended at 23 o'clock on August 12, 1998, and is therefore going to watch a part of the broadcast S11 broadcast between 22:00 and 23:00 on that day. Confirm.

For this purpose, the user of the video recorder 1 only needs to input “22:00” as the reproduction time information WXI for specifying the desired reproduction time point GT 2 by using the reproduction time point button 33.
The control unit 21 performs the programming during the programmed period VD2 = WZI-T1 = 22: 00-1
It is configured to lead 3: 00 = 9: 00. As described above, the control unit 21 determines the obtained VD2 = 9: 00 and the actual playback period determined by the tape length counter 26.
WD2 = 5: 00, and as a result, it is determined that the magnetic tape 5 should be transported toward the end of the magnetic tape 5, and the magnetic heads 7 and 8 are positioned at the desired recording medium position GP2. After that, the control unit 21 activates the long play playback mode of the video recorder 1 and displays the last part of the program “East of Eden”.

As described with respect to the second embodiment, the user of the video recorder 1 can simply input the reproduction time information WZI to the desired recording medium position P of the magnetic tape 5 to set the magnetic head 7 of the video recorder 1. And 8 and then this recording medium position P
Can be played back from

It should be noted that the playback device can also be constituted by a DVD player in which the optical playback head is located at the desired recording medium position on the optical data carrier.

It should be noted that, alternatively, the input means may include a button on the housing of the video recorder 1 instead of the remote control 29.

It should be noted that the input means for inputting the numerical code information can be constituted by a bar code reader for reading the bar code of each broadcast printed on the program magazine.

It should be noted that, as an alternative, the playback device according to claim 1 can be constituted by a magnetic tape as a data carrier or an audio recorder for recording and playing back audio information on a rotationally driven disk.
