Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus and a reproducing apparatus suitable for being applied to various VTRs such as so-called high definition VTRs.

[0002]

2. Description of the Related Art Conventionally, a DAT (Digital Audio Tape Recorder) is generally used as a device for recording or reproducing information, for example, by forming a slanted track on a magnetic tape by a rotary head and reproducing the information. Widely used regardless.

In this DAT, a start ID is used as a sub-code related to operations such as reproduction, fast forward and rewind.
IDs such as (identifier), skip ID, and end ID are used.

The start ID is a signal indicating the beginning of a lump of voice (for example, a piece of music) in DAT. The start ID is recorded in a mode automatically recorded when the voice is recorded, a user operates an operation key, etc. There are three types of modes: a mode in which the start ID is manually recorded during recording of a voice by using, and a mode in which the user operates an operation key or the like to manually record the start ID during reproduction of the voice.

In the mode in which the start ID is automatically recorded, the start ID is recorded on the magnetic tape when the voice supplied to the DAT is not present for a predetermined time (for example, 3 seconds), that is, when the silent state is detected. It is designed to be done.

In a mode in which the user manually records the start ID during reproduction and recording, the user can
The start ID is recorded on the magnetic tape when the T operation key or the like is operated.

Further, the program number is automatically or manually recorded at the same time when the start ID is recorded.

The start ID is a signal indicating the beginning of a predetermined unit of voice such as a song, and the program number is such as a song.
This is a number of a predetermined unit of voice, and this number is external or DAT.
By inputting by operating the operation keys on the operation panel, it is possible to perform the so-called cueing of information in a predetermined unit of voice such as a piece of music to which this number is assigned.

As for the skip ID, this skip ID is DA
When T is detected, it is an ID for skipping a song by, for example, fast-forwarding until the next start ID is detected.

The recording of the skip ID includes automatic and manual recording similarly to the recording of the start ID.

The end ID is a signal indicating the end position of recording or reproduction, and when the DAT detects this end ID during reproduction, the end is stopped and the rewinding operation is automatically performed.

Recording of this end ID is performed by operating any one of the buttons such as a pause button, a recording mute button, and a fader button during recording, and then operating an operation key or the like. It may be recorded by operating an operation key or the like during reproduction.

In DAT, such a start I
You can use D, Skip ID, End ID, etc. to find what is called a song, skip a song you want to skip, or automatically rewind when all the recorded songs are finished. It is made possible.

[0014]

By the way, the DAT start I described above is applied to a VTR or the like for recording a video signal of a high-definition system, NTSC, PAL, or SECAM system.
There is a desire to introduce the concepts of D, skip ID and end ID.

One of the reasons for the demand for the introduction of each ID is, for example, when a television broadcast (including a high-definition broadcast) is recorded, it is inserted (or incorporated) in one program (main part) of a television program. (Advertisement) (advertisement) will also be recorded together, which will be very annoying for the user who wants to see only the main part.

That is, when watching a recorded program, every time the advertisement is started, the operation of skipping the advertisement part by variable speed reproduction or the like to search for the main part, or waiting for the main part to start after the end of the unwanted part of the advertisement That is.

Therefore, as described above, there is a demand for introducing the concept of start ID, skip ID and end ID in DAT into a VTR or the like for recording a video signal.

However, the above-mentioned D is added to the VTR for the video signal.
A big problem arises when the concept of various IDs in AT is introduced.

This problem will be described with reference to FIG. 15. FIG. 15A shows a state in which programs (main part) a and b are recorded on a tape together with a commercial cm.

As described above, when the concept of various IDs conventionally used in DAT is introduced into the VTR as it is, as shown in FIG. 15A, programs a and b are used.
After or during recording, the start ID is recorded at the beginning of each of the programs a and b.

Then, as shown in FIG. 15B, for example, a skip ID for skipping and reproducing the commercial cm (two places in the program a, one place in the program b) is reproduced.
When is recorded, normal reproduction is performed up to the place where the skip ID is recorded, as shown in FIG. 15B.
After detecting the skip ID, it will be fast forward (forward),
When the start ID is detected again, the normal reproduction state starts.

That is, the reproduction is started by the detection of the start ID of the program a, and then the skip ID is detected, so that the program is fast-forwarded to the position where the start ID of the next program b is recorded. All parts after the first commercial cm will be skipped (meaning that they will not be played).

Therefore, even though the user wants to skip the two commercial cms of the program a and see, only the first part is reproduced, and the program b is reproduced immediately after being skipped by fast forward. Become.

Similarly, if the user wants to see the program b without the commercial cm, and if a skip ID is recorded at the position of the commercial cm, the commercial c is reproduced, but the commercial c is reproduced.
After m, it will be skipped by fast-forward, and program b
I will not be able to see the second half of.

The present invention has been made in view of the above points, and a recording apparatus that can obtain a recording state in which only a portion that is not desired to be reproduced when reproduced by the reproducing apparatus and a portion that is not desired to be reproduced are obtained. It is intended to propose a reproducing device capable of skipping only.

[0026]

The recording apparatus of the present invention, for example, as shown in FIGS. 1 to 14, is a recording apparatus for recording information on a magnetic tape 12, and an identifier related to the running speed of the magnetic tape 12 is used. The generating means 9 for generating is provided,
An identifier is recorded on the magnetic tape 12.

The reproducing apparatus of the present invention is, for example, shown in FIGS.
As shown in FIG. 3, reproducing means 8, 4, 13, 14, 9 for reproducing the magnetic tape 12 in which an identifier related to the traveling speed of the magnetic tape 12 is recorded, and tape traveling means 5, 6 for causing the magnetic tape 12 to travel. , 7 and control means 9, 1 for performing control relating to the traveling speed of the magnetic tape 12,
The tape running means 5, 6, 7 are controlled in relation to the identifiers reproduced by the reproducing means 8, 4, 13, 14, 9.

[0028]

According to the present invention described above, since the identifier relating to the running speed of the magnetic tape 12 is recorded on the magnetic tape 12, it is possible to prevent the reproducing device from reproducing only a portion which is not desired to be reproduced. It is possible to obtain a recording state that can be obtained, and to improve usability.

Further, according to the present invention described above, the tape running means 5, 6, 7 are controlled in relation to the identifiers reproduced by the reproducing means 8, 4, 13, 14, 9. It is possible to play only the part that you do not want to play, which improves usability.

Automatically skip parts other than the main part such as programs that you do not want to see or want to skip (which means fast-forwarding) so that the user can play only the parts you want to see.

The subcode (HD video subcode) in this example is a time code, a head start signal, a program number, and TOC (Table Of Contents).
Is encoded according to the HD video subcode format.

This subcode is an optional function for making the VTR easy to use, and some VTRs that cannot record and reproduce video subcodes are also allowed.

The signal processing of the video subcode is performed by, for example, a PC.
It can be shared with M voice signals, and the error correction code is C
Only 1, and the modulation method is the 8-10 modulation method.

The concept of the subcode peculiar to this embodiment and the operations of the recording apparatus and the reproducing apparatus of this embodiment according to the subcode will be described in detail with reference to FIGS.

First, the subcode will be described with reference to FIGS.

FIG. 8 shows the structure of the tape on which the HD video subcode is recorded.

In FIG. 8, as an example, the case where the program a, the program b and the program c as the main part are recorded is shown.

The recording area is composed of programs a, b and c and a lead-out area, and the program area is composed of programs a, b and c.

Further, various sub-code data shown in FIG.
Recording can be performed in the areas indicated by the arrows below in FIG.

FIG. 9 shows the relationship between the recording area and HD subcode data.

In FIG. 9, the pack data P1 includes absolute time (absolute time), program time (main program time, etc.), index time, date, time,
It is composed of a caption and dubbing mark.

The subcode ID data 1 is composed of a start ID and a program number ID.

The subcode ID data 2 is a skip start ID, skip end ID, format ID and T
It is composed of an OC (table of contents) ID.

The above-mentioned skip start ID and skip end ID are IDs peculiar to this example. When the skip start ID is detected, for example, fast forward is performed until the next start ID or skip end ID is detected. Is an ID for.

The pack data P2 is TOC-1 and TOC.

The recording date and time is calendar 1 and calendar 2.
Is.

The caption is a caption.

The recorded contents list is TOC-1 and TOC-2.
Is.

Now, the track format of the video subcode will be described with reference to FIG.

As shown in FIG. 12, the video subcode area is composed of, for example, 14 blocks per track, the preamble part is composed of 9 blocks, the postamble part is composed of 1 block, and the data part is composed of 4 blocks.

Each of these blocks has 41, 4 at the bottom of the figure.
Addresses are assigned as indicated by 2, ... 49 ,.

The same data is recorded on the two tracks constituting one segment.

The preamble and postamble parts described above are composed of sync, w1, w2, parity and a predetermined same pattern, and the data part is composed of sync, w1, w2,
It is composed of parity and a plurality of pack data.

Of the pack data, a predetermined pack data is recorded, for example, when the start ID is detected, the speed at which the vehicle travels up to the next start ID is recorded, or when the skip start ID described later is detected. The data is data for determining the running speed of the tape 12 until the start ID or the skip end ID is detected.

As shown in FIG. 10, for example, when the data indicated by S is "0", the vehicle is allowed to travel in the forward direction after the skip D is detected and before the next start ID or skip end ID is detected. When the value is "1", the vehicle travels at the cue 1 from the time when the skip D is detected to the time when the next start ID or skip end ID is detected, that is, at a speed of 3.5 times the normal reproduction speed. When it is "2", the vehicle travels in the cue 2 from the detection of the skip ID to the detection of the next start ID or skip end ID, that is, at a speed of 9.5 times the normal reproduction speed. Done

The above w1 and w2 are constructed together with a segment address as shown in FIG. 13, a block address is recorded in w1, and a video subcode I is recorded in w2.
D is recorded.

This subcode ID is composed of a control ID and a format ID.

In the area where the control ID is recorded, a skip start ID and a skip end ID, which are subcodes peculiar to this example, are recorded.

The control ID described above with reference to FIG.
The recorded contents of will be described in detail.

First, for example, a skip end ID is assigned to the least significant bit, and when this skip end ID is valid, that is, "1", it indicates the end of the portion not to be reproduced, and this information is, for example, 300 ±. It is recorded continuously for 30 frames, and if this skip end ID is not valid, that is, "0", it indicates that it is not the end of skip.

For example, TOC is set in the third highest bit
ID is assigned and this TOCID is valid, ie
In the case of "1", it indicates that TOC exists, and when this TOCID is not valid, that is, in the case of "0",
Indicates that no TOC is present.

For example, a skip start ID is assigned to the second highest bit, and when this skip start ID is valid, that is, "1", it indicates the start of a portion not to be reproduced, and this information is, for example, 30 ±. It is recorded continuously for 30 frames, and if this skip start ID is not valid, that is, "0", it indicates that it is not the start of skip.

A start ID is assigned to the most significant bit, and this start ID is valid, that is, "1".
Indicates the beginning of the program, this information is recorded continuously for 300 ± 30 frames, for example, and if this start ID is not valid, that is, if it is “0”, it indicates that the program does not start. Show.

Now, these IDs can be recorded, for example, automatically or manually, and in particular, the skip start ID and the skip end ID are recorded in the above-mentioned predetermined area by operating a predetermined key of the operation panel 3 shown in FIG.

Next, with reference to FIG. 2, a case where the above-mentioned skip start ID and skip end ID are automatically recorded will be described.

First, in step 100, the time code is stored. Then, the process proceeds to step 110.

That is, the time code is stored by operating a predetermined key (not shown) on the operation panel 3 shown in FIG.

Explaining to the user side, the time code of the position (position on the tape) where the skip start ID or the skip end ID is desired to be recorded is checked in advance, and the time code is input through the operation panel 3.

At step 110, the recorded part of the stored time code is searched. Then, the process proceeds to step 120.

That is, for example, the time code is read by high-speed reproduction or the like, and it is determined whether the read time code matches the time code input by the user.

In step 120, it is judged whether or not the search is successful, that is, whether the time code read from the tape 12 matches the time code input by the user. If "YES", the process goes to step 130. Migrated,
If “NO”, the process proceeds to step 110 again.

At step 130, the operation is stopped. Then, the process proceeds to step 140.

That is, a control signal is supplied to the motor control circuit 5 to stop the capstan motor 6.

At step 140, rewinding is performed. Then, the process proceeds to step 150.

That is, a control signal is supplied to the motor control circuit 5 to drive the capstan motor 6 and the reproduced time code is read. This operation is an overrun countermeasure operation, and therefore, the rewinding speed is set to a speed at which overrun does not occur when stopped.

At step 150, it is judged whether or not the read time code matches the stored time code, and if "YES", the routine proceeds to step 160, where "N"
If "O", the process proceeds to step 140 again.

At step 160, skip start I
Record D or Skip End ID.

Next, the case of manually recording the skip start ID or the skip end ID will be described.

First, at step 200, a manual search operation is performed. Then, the process proceeds to step 210.

That is, by the operation of the operation panel 3 by the user, for example, reproduction or shuttle reproduction in the shuttle mode is performed.

At step 210, the jog dial (not shown) of the operation panel shown in FIG. 1 by the user.
In response to the operation, the motor control circuit 5 is supplied with a control signal to control the capstan motor 6 and the magnetic tape 12 is fed frame by frame, for example, so-called frame feed operation.

Explaining to the user side, the user will carefully check the points to be skipped frame by frame.

At step 220, skip start I
It is determined whether or not there is a recording operation of D or the skip end ID. If “YES”, the process proceeds to step 230, and if “NO”, the process proceeds to step 210 again.

That is, the skip start ID or the skip end ID is recorded at a predetermined position on the magnetic tape 12 by the user operating a predetermined key on the operation panel 3.

In order to prevent erroneous recording, for example, a state in which no skip end ID or start ID is recorded between the skip start ID and the next skip start ID, a warning is given to the user at the time of input. You may do it.

Next, referring to the flowchart of FIG.
The operation peculiar to this example in which only the desired part of the program is viewed will be described.

First, in step 300, reproduction is started by operating the operation panel 3. And step 31
After 0.

At step 310, the magnetic tape 12 is reproduced. Then, the process proceeds to step 320.

As described above, when the magnetic tape 12 is reproduced, the video signal, the audio signal and the sub-code are respectively supplied to the video signal processing circuit and the audio signal processing circuit via the switch 4, the reproduction amplification circuit 13 and the switch 14. (Neither of which is shown) and the signal processing circuit 9.

The signal processing circuit 9 decodes the subcode by the decoding section 9c, and the system controller 1 decodes the subcode.
Supply to.

At step 320, skip start I
It is determined whether or not D, that is, whether or not the skip start ID is valid, and if “YES”, the process proceeds to step 330,
If “NO”, the process returns to step 310.

At step 330, the fast-forwarding operation (reproduction speed several times higher than the normal reproduction speed) for the magnetic tape 12 is automatically performed. Then, the process proceeds to step 340.

That is, by supplying a control signal to the motor control circuit 5 and controlling the capstan motor 6, the running speed of the magnetic tape 12 is increased to the fast-forward speed.

At step 340, the skip end ID
Or, judge whether the start ID is valid, and "YES".
If so, the process proceeds to step 350, and if “NO”, the process proceeds to step 330 again.

That is, the skip end ID of the subcode supplied from the signal processing circuit 9 during the above-described fast-forward operation.
Alternatively, it is determined whether or not the start ID is valid.

At step 350, the operation is stopped. Then, the process proceeds to step 360.

That is, a control signal is supplied to the motor control circuit 5 to stop the capstan motor 6.

At step 360, the magnetic tape 12 is rewound. Then, the process proceeds to step 370.

That is, the control signal is supplied to the motor control circuit 5 to control the capstan motor 6 to perform the rewinding operation, the subcode from the signal processing circuit 9 is read, and the skip end detected in step 340 is executed. Detect ID or start ID.

As described above, this rewinding is step 3
This is a countermeasure against overrun at 40, and therefore, the rewinding speed is set to a speed at which overrun does not occur.

When searching for this skip end ID or start ID, a time code may be used.

As described with reference to FIG. 14, the skip end ID and the start ID are recorded for 300 frames ±.
The reason for setting 30 frames is that the skip end ID and the start ID can be read when the fast-forwarding is performed as described above.

Although it overlaps, the operation described above will be described below with reference to FIG.
This will be described in more detail with reference to the timing chart of FIG.

FIG. 5A shows the start ID. As shown in FIG. 5A, the start ID is recorded at the beginning of the program.

Further, as shown in FIG. 5B, for example, when there is a portion S such as a commercial that is not desired to be reproduced at the end of the program a and the skip start ID is recorded at the beginning of this portion S, the program When the start ID at the beginning of a is detected and the program a is reproduced, and when the skip start ID is detected, this portion S is skipped by fast-forwarding or the like, and the start ID recorded at the beginning of the program b is detected and reproduced. I do.

In FIGS. 5C and 5D, the skip start ID is recorded across the programs a and b.

In this case, only the portion where the skip start ID and the start ID recorded at the beginning of the program b do not overlap, that is, the portion S is skipped by fast-forwarding or the like.

Further, FIGS. 5E and 5F show the case where the skip start ID is recorded so as to overlap the start ID recorded at the beginning of the program a.

In this case, the skip start ID is skipped by fast-forwarding or the like until the start ID recorded at the beginning of the program b is detected from the portion recorded, and the reproduction is performed when the start ID of the program b is detected. ..

Therefore, as shown by S, the range to be skipped is
The program a is almost skipped.

FIGS. 5G, 5H and 5I show the period of program a,
In addition, the skip start ID and the skip end ID are recorded in this order at positions that do not overlap with the start ID of the program a.

In this case, from the position where the skip start ID is recorded to the start position where the skip end ID is recorded, that is, the period of the portion S is skipped by fast-forwarding or the like, and from the start position of the skip end ID. Is in the playback state.

The most basic operation will be described with reference to FIG. 6. The reproduction state is up to the position where the skip start ID is recorded, the fast forward is started from the position where the skip start ID is recorded, and the skip end ID or It stops before the beginning of the position where the start ID is recorded (including the overrun portion), and further rewinds once to return to the position of the skip end ID or the start ID, after which the reproduction state is set.

As described with reference to FIG. 10, the skipping speed from the detection of the skip start ID to the detection of the start ID or the skip end ID is, for example, the speed recorded in the pack data. To do so.

As shown in FIG. 7A, the magnetic tape 12 has a start ID, a skip start ID, and a skip end I.
When the IDs are recorded in the order of D and the start ID, as shown in FIG. 7B, the reproduction is performed up to the beginning of the skip start ID, and the skip end ID is recorded from the position where the skip start D is recorded. The speed of cue 1 to the existing position (until the end), that is, FIG.
As described above, for example, at the normal reproduction speed of 3.
Try to run at 5 times speed.

Then, as shown in FIG. 7B, after the skip end ID is detected, rewinding is performed to correct the overrun amount, and an accurate position, that is, the head position where the skip end ID is recorded. Then, after that, the reproduction state is set.

As described above, in this example, the skip start ID, the skip end ID and the start ID can be recorded, and from the time when the skip start ID is detected to the position where the skip end ID or the start ID is recorded. Since I'm trying to skip fast forward, I can skip only these things if I don't want to play.

Also, skip end ID and start ID
Since the recording length of is increased to 300 frames ± 30 frames, it can be detected even when the tape running speed is high.

The above embodiment is an example of the present invention.
Of course, various other configurations can be adopted without departing from the scope of the present invention.
