Description

Method for reproducing a recording signal with positioning means

An apparatus of this kind mentioned at the outset is known from document US 5,661,847 A and is formed by a video recorder. Known video recorders are capable of recording the recording signal of one or several broadcasts starting at the recording medium start position of the magnetic tape and starting at the start of the recording on the recording tape tracks of the magnetic tape in the recording mode. Let's do it. The recording medium starting position defines the position on the magnetic tape on which the recording signal is recorded, while the recording start instant is the actual time at which recording of the signal to be recorded starts.

Known video recorders have an index signal generator that writes an index signal in a linear recording track of a magnetic tape at the beginning of each broadcast of a recording session. The index signal is formed by a so-called VISS signal (Video Index Search System). A VPS detector (Video Program System) is designed to detect VPS signals belonging to each broadcast and characterizing each broadcast. Whenever the VPS detector detects a change in the VPS signal, indicating the start of a new broadcast, it is possible to provide a control signal to an index signal generator that generates and records the VISS signal.

The known video recorder has two magnet heads which can be driven in rotation and fixed to the head disk of the scanner, which forms the playback heads in the playback mode of the video recorder and the recorded signals on the magnetic tape It is further provided with reproducing means that can be reproduced.

The known video recorder further comprises a positioning means comprising a remote control and a magnetic tape drive device. The index search signal can be supplied to the video recorder from a remote control in the playback mode of the video recorder for the purpose of positioning the magnet heads to the desired recording medium position where the broadcast of the recorded signal begins. This index search signal has information, for example, about the effect that the third broadcast recorded on the magnetic tape, starting at the current recording medium position, in the end direction of the magnetic tape is to be reproduced. When this index retrieval signal is received by a known video recorder, the magnetic tape transporting device is capable of reproducing the position of the magnetic tape when the desired recording medium position is reached at a speed that is multiple reproduction speed until the index signal is retrieved for the third time. The magnetic tape is driven in the end direction and then the recorded signal is reproduced by the reproducing means at the normal reproduction speed. This procedure is known as index search mode. The magnet heads can be quickly positioned to the desired recording medium position at the start of the recorded broadcast.

However, it is known to the known video recorder that the recording medium position where the magnet heads are positioned by the positioning means in accordance with the actual recording medium position at the moment when the index search signal is received. For example, if a recorded signal of seven broadcasts is recorded on a magnetic tape, the onset of each broadcast is characterized by an index signal and at the start of the third broadcast the positioning of the magnet heads towards the end of the tape. The index search signal is thereby provided by the remote control, and the positioning means is capable of setting the magnet heads at the recording medium position at which the third, fourth, fifth, sixth or seventh recorded broadcast starts.

As soon as the index search signal is received, if the actual recording medium position is capable of instant reproduction of the recorded signal of the second broadcast recorded on the magnetic tape, for example, as calculated at the start of the magnetic tape, the magnetic tape drive apparatus When the index search signal is provided, the magnetic tape will be driven so that the recorded signal of the fifth broadcast recorded on the magnetic tape is reproduced by the reproducing means.

On the other hand, when the actual recording medium position is calculated at the start of the magnetic tape, when the recorded signal of the fourth broadcast recorded on the magnetic tape is capable of reproduction, the magnetic tape drive apparatus is provided with an index search signal, The reproducing means will drive the magnetic tape to reproduce the recorded signal of the seventh broadcast recorded on the magnetic tape. Known video recorders have the disadvantage that the positioning of the magnet heads to the desired recording medium position is only possible while considering its actual current position on the recording medium.

A further disadvantage found in the known video recorders is that the magnet heads can only be positioned by the index search signal to their recording medium positions, on which index signals are recorded. For example, a quick discovery of the recording medium position where the recorded signal of the third recorded broadcast is recorded 15 minutes after the start of this third broadcast is not possible in a video recorder for which the start of the third broadcast is known.

The present invention has a reproducing means for reproducing a recorded signal recorded on a recording medium starting at the moment of recording start by the at least one reproduction head and starting at the recording medium starting position of the recording medium, and starting at this recording medium position.

Will be.

The operation of the video recorder 1 will now be described in more detail with reference to the first embodiment and with reference to FIGS. 2, 3 and 4. 2 shows a portion of a page in program magazine 34 of August 12, 1998. FIG. The page of this program magazine 34 is shown. Start times, show viewing codes and titles of programs broadcasting on station ORF1 in the form of an input signal (ES) from this station ORF1 on 12 August 1998. FIG. For example, a program titled "Side Glances" is displayed that starts at 12:30. The show viewing code "17345" includes date information DI representing the date "12.08.98", time information ZI representing the start time "12:30", and a broadcast station identifier SKI "ORF1" in encoded form. Form a male cord. Show viewing code is used in video recorders to program broadcast records that are shifted sooner or later.

It is this first that the user of the video recorder 1 operates the record button 31 to record the input signal ES of the station ORF1 at 13:00 and activates the long play recording mode in the video record 1. In the example is estimated. This is because the long play recording mode of the video recorder 1 is not released until 23:00 after a 10-hour recording duration period, and in the broadcasts S1 to S11, the recording signal AS is recorded on the magnetic tape 5. Is also estimated.

3 shows the recording medium positions P on the magnetic tape 5 starting from the beginning of the recording ranges and the magnetic tape 5 at the recording medium position P1 and to the end of the magnetic tape 5 at the recording medium position P12. ) Is schematically shown. This represents each recording range of the magnetic tape 5 belonging to the recording signal AS in which the broadcast S is recorded on the magnetic tape 5. For example, the news-from broadcast S1-13: 00 to 13:20 is recorded on the magnetic tape 5 from position P1 to position P2. The recording medium positions P1 to P11 characterize the position on the starting magnetic tape 5 on which the recording signals AS of the broadcasts S1 to S11 are recorded.

FIG. 4 schematically shows the time range and the moment T on the magnetic tape 5 on which the recording signal AS was recorded for 10 hours from the moment T1 to the moment T12 in the long play recording mode. The recording medium start instant T1 corresponds to the actual time 13:00 at the start of recording of the programs S1. The moments T1 to T11 correspond to the starting moments of the programs S1 to S11 listed in the program magazine 34. For example, the input signal ES of the program S5 entitled "Universe" is on the magnetic tape 5 from the recording medium position P5 to the recording medium position P6 like the recording signal AS. Broadcast at 15:35 by the recorded station ORF1. The instant T5 corresponds to the start time 15:35 of the program S5 "Universe" listed in the program magazine 34.

Immediately after the long play recording mode is activated, the control unit 21 described in the actual time information (ZI = 13: 00) supplied by the clock component 22, such as the start time information PZI, is executed at the recording start instant ( T1) and the position at the start of the magnetic tape 5, such as the recording medium starting position P1, during this recording. In addition, the actual date information (DI = 12.08.98) supplied by the clock component 22 is recorded by the broadcast station identifier determined by the signal processing means 19 in the recording date information ADI, the input signal ES during this recording. It is written with information (SKI). This start time information (BZI), this recording date information (ADI) and this station identifier information (SKI) were recorded in the linear recording track of the magnetic tape 5 according to the VASS standard throughout the entire recording session of 10 hours.

The video recorder 1 after the video cassette comprising the magnetic tape 5 is inserted into the video recorder 1 and recorded once again on August 15, 1998, for example, three days later, for example, three days later. This first embodiment, which was received at), is assumed. In addition, the video recorder 1 is configured to execute an initialization routine immediately after the video cassette is inserted, in a manner not shown in more detail in FIG. 1. In this initialization routine, the playback mode of the video recorder 1 reproduces the information according to the VASS standard recorded in the linear recording track of the magnetic tape 5 and displays it on the display 24 for a short time, for example. For example, it is activated for 5 seconds. In addition, during the initialization routine, the actual reproduction time period WD and the actual recording medium position AP are determined by the tape length counter 26, as described above.

It is assumed as a first example that the actual reproduction time period WD1 = 01:15 and the actual recording medium position AP1 are determined by the tape length counter 26. The information shown on the display 24 is recorded on the magnetic tape 5 of the video cassette in which the broadcast S of the station ORF1 of August 12, 1998, which starts at 13:00 after the initialization routine, is inserted into the video recorder 1. To the user of the video recorder 1. The user of the video recorder 1 is likely to select the broadcast S he / she is interested in in the program magazine 34 shown in FIG.

It is also assumed in this first example that the user of the video recorder 1 wants to see the program S7 whose title is "Titanic". Advantageously, the user of the video recorder 1 forms a desired playback moment GT1, such as the playback time information WZI, by the playback moment button 33, so that the start time displayed for the program "Titanic" 17:00. It is intended to be inserted at the time. The control unit 21 is characterized by the recording start instant T1 at the recording time information WZI = 17: 00, which is characterized by the desired playback instant GT1 for determining the programmed time period VD1 = 4: 00. It is designed to subtract the start time information (BZI = 13: 00). The comparison of the actual playback time period (WD1 = 1: 15) determined by the tape length counter 26 having the programmed time period (VD1 = 4:00) determined above allows the magnetic tape 5 to desire the recording medium position GP1. In the control unit 21 it can be determined that the drive in the direction towards the end of the magnetic tape 5 for the positioning of the magnet heads 7 and 8. The control unit 21 lowers motor control information (MSI) related to the motor 16. The magnetic tape 5 is transported toward the end of the magnetic tape 5 with the speed of multiple reproduction speeds. When the actual playback time period WD, which is continuously monitored by the tape length counter 26 during the drive movement of the magnetic tape 5, reaches the desired recording medium position GP1, the pro When determining in response to the ram time period VD1 = 4:00, the control unit will be activated in the long play playback mode in the video recorder 1 to show the recorded program "Titanic".

Advantageously the magnet heads 7 and 8 are positioned with the desired medium position GP1 selected by the user of the video recorder 1, and the selected program S7 is then displayed. All users of the video recorder 1 must enter the start time of the selected program S7 displayed in the program magazine 34 without consideration of the current recording medium position AP1 of the magnetic tape 5.

Alternatively, in addition, the start time information BZI is a recording signal reproduced with this first embodiment of the video recorder 1 so that the user of the video recorder 1 does not need to write the start time information BZI. Is determined.

In particular an advantage is the use of a linear recording track of the magnetic tape 5 as a storage means for storing start time information BZI and other information as a result that separate memory means are not needed in the video recorder 1. An additional advantage is that a cassette comprising the magnetic tape 5 can also be inserted into another video recorder according to the invention, and the information recorded in the linear recording track also positions the magnet head to the desired recording medium position GP. To be used in other video recorders.

This is particularly advantageous in recording the above-mentioned information on the linear recording medium of the magnetic tape according to the VASS standard, where the data rate that can be recorded on the linear recording track is high enough and substantially additional hardware requires the video recorder 1. Because it does not.

It should be noted that the advantage in a digital video recorder in which the method of claim 1 is accepted and records signals in accordance with the DVHS standard is to record the information described above in the sub-code of the recorded signal.

Advantageously, the video recorder 1 always has a magnetic tape 5 because the recording medium starting position P1 does not need to be stored in the video recorder 1, and there is no need to put it by the user of the video recorder 1. Is placed at the recording medium start position P1 at the beginning of the " In addition, this drop is likely to record programs on the entire magnetic tape 5.

However, it can be noted that any desired recording medium starting positions are possible and also some recording medium starting positions are possible in the case of several recordings on one magnetic tape. In this case, it is possible to clearly characterize the recording medium position through the input of the reproduction time information and the recording date information and the magnet heads can be positioned to the recording medium position. For example, a video recorder would be set up to reach the end of the magnetic tape for daily signal recording from 20:15 to 22:15, rewinding to the beginning of the magnetic tape and overwriting previous signals. The recorded program will be playable by the video recorder through input of playback time information (WZI = 20: 15) and recording date ADI corresponding to the desired broadcast.

It should be noted that the method according to the invention may be provided with certain advantages, a so-called Time Lapse Recorder, designed for recording single pictures for very long recording times.

According to the first example, the user of the video recorder 1 can also write the show viewing code "17845" of the broadcast S7 whose title is "Titanic" as the number code information. The control unit 21 obtains the reproduction time information (WZI = 17: 00) from the written show viewing code, and the magnetic tape 5 is transported to the desired recording medium position GP1.

The video recorder 1 stores the date information DI present in the show viewing code characterizing the date of the recording signal AS and the recording date determined during the initialization routine, when the desired reproduction time information is written in the form of the show viewing code. It should be noted that it may be designed to compare the record of the information ADI, and it may be possible to show the information on the display of the video recorder 1 if the two date information do not match.

In the second example, the user of the video recorder 1 recognizes after he has watched a part of the broadcast S7 at the actual recording medium location AP2 so that he wants to watch the broadcast S11 entitled "East of Eden". do. Since he has only one hour and has already seen the beginning of this broadcast S11 once, the user decides whether to watch the last time of the broadcast S11. The user wanted to see a part of the broadcast (S11) that was removed at 23:00 on August 12, 1998, exactly the broadcast (S11) broadcasted from 22:00 to 23:00 on that date, and the program magazine (34) Recognize in.

Advantageously, the user of the video recorder 1 has the purpose of writing "22:00" as the reproduction time information WXI characterizing the desired reproduction moment GT2 by the reproduction moment button 33. The control unit 21 is configured to derive the programmed time period (VD2 = WZI-T1 = 22: 00-13: 00 = 9:00), as described above. The control unit 21 compares the actual playback time period (WD2 = 5: 00) determined by the tape length counter 26 with the determined programmed time period (VD2 = 9: 00) and the magnetic tape is the magnetic tape (5). It determines that it is to be transported toward the end of and positions the magnetic heads 7 and 8 at the desired recording medium position GP2 as described above. Next, the control unit 21 activates the long play playback mode in the video recorder 1 to watch the last part of the program "East of Eden".

As described with reference to the second example, the user of the video recorder 1 can write this recording medium through simple writing of the playback time information WZI as well as any desired recording medium position P of the magnetic tape 5. The next reproduction starting at position P can achieve the positioning of the magnet heads 7 and 8 of the video recorder 1.

It should be noted that the reproducing apparatus may also be formed by a DVD player in which the optical reproducing head is positioned at a desired recording medium position of the optical data carrier.
