Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording system, a reproduction system, and a recording or reproduction control method, and more particularly to a recording system and a reproduction system for recording and reproducing digital data corresponding to a tape-shaped recording medium. The present invention relates to a system and a recording or reproduction control method.

[0002]

2. Description of the Related Art In recent years, a tape recorder such as a digital VTR has been known as a recording / reproducing apparatus capable of recording / reproducing digital image data corresponding to, for example, a tape-shaped recording medium (magnetic tape). In recent years, digital broadcasting for transmitting (broadcasting) video information converted into digital data and its additional information by using broadcast waves by digital modulation has become widespread.

With this background, for example, when recording a digital broadcast video on the digital broadcast receiving side, the broadcast video data is converted into digital data without being once converted into an analog signal. It is conceivable that the recorded video information is directly recorded on a digital tape recorder or the like.

[0004] In the above-described digital tape recorder, in order to appropriately perform the recording / reproducing operation on the magnetic tape of the tape cassette, for example, management information used by the digital tape recorder for managing the recording / reproducing operation and the like. As such, various pieces of positional information on the magnetic tape, information related to the usage history of the magnetic tape, and the like are required.

Therefore, it has been considered to provide such an area of management information at the head of the magnetic tape or at the head of each partition. Then, on the digital tape recorder side, before executing the data recording or reproducing operation on the magnetic tape,
The required management information is read by accessing the area of the management information, and various processing operations are executed based on the management information so that the subsequent recording / reproducing operation is properly performed. After the data recording or reproducing operation is completed, the management information area is again accessed by re-accessing the management information area in order to rewrite the contents of the management information which needs to be changed in accordance with the recording / reproducing operation. Is rewritten to prepare for the next recording / reproducing operation. Thereafter, the tape cassette is unloaded and ejected by the digital tape recorder.

[0006]

However, when the recording / reproducing operation is performed based on the management information as described above, the digital tape recorder performs magnetic recording at the start of the operation regardless of the recording / reproducing operation. In addition to accessing the management information area at the head of the tape or the partition, it is necessary to access this management information area to write / read information at the end. In other words, with such a tape recorder, loading and unloading cannot be performed at a position on the magnetic tape where data recording / reproduction has been completed. In addition, in the case of such a digital tape recorder, it is necessary to physically send a magnetic tape for access, and therefore, at the end of recording / reproduction, an area of management information at the head of the magnetic tape or the head of a partition is accessed. This will take a considerable amount of time. In particular, when data recording / reproduction is completed at a position physically far from the management information area on the magnetic tape, the amount of the magnetic tape to be sent increases accordingly, which takes extra time. .

For this reason, for example, when recording the above-mentioned digital broadcast image on a digital tape recorder, a process of sending the magnetic tape from the head position to the recording start position in the middle is required each time. Work efficiency is considerably reduced. Such a process of feeding the magnetic tape is also required during reproduction. That is, in the digital tape recorder, it is required that the time required for access at the start and end of the recording / reproducing operation be reduced as much as possible.

[0008]

And a control device capable of controlling the reproduction operation of the reproduction device based on the management information held in the storage means.

[0010] Further, the control device uses the management information read from the storage device to form an interface image for performing a recording / reproducing operation on the recording or reproducing device and display and output the image. And the control device is provided for a computer device connected to the recording device or the reproduction device.

As a recording or reproducing control method for a recording or reproducing apparatus for recording or reproducing data corresponding to a tape-shaped recording medium, management of recording or reproducing of data recorded on a tape-shaped recording medium is performed. Create the required management information for, and store the created management information in a predetermined storage area other than the tape-shaped recording medium, based on the management information stored in the storage area,
The digital data recording / reproducing operation on the tape-shaped recording medium can be controlled.

According to the above configuration, for example, the control unit stores and holds the storage information in a storage unit other than the tape-shaped recording medium. The control unit reads out the management information held in the storage unit and records the management information. It is possible to execute recording / reproduction control for the device or the reproduction device. This eliminates the need for the recording device and the reproducing device to access, for example, the storage area of the management information at the head of the magnetic tape at the start and end of the recording / reproduction. Further, the control device can display an interface image for a recording / reproducing operation on the recording device or the reproducing device by using the management information. In this case, the management information is read from the storage unit. Therefore, it is possible to quickly execute display control for displaying an interface image.

FIG. 2 is a block diagram showing an internal configuration of a digital tape recorder 6 which is a recording / reproducing apparatus of the present embodiment, and schematically showing an interface between the digital tape recorder 6 formed via an IF board 5 and a computer device 3. is there. In this figure, first, a bus line 21 for data transmission in the computer device 3 is shown. Here, PCI (Peripheral Component In
terconnect) bus. In addition,
A bus line based on another standard may be adopted without being limited to the PCI.

The I / F board 5 includes, for example, an I / F conversion processing unit / control unit 22, a bank RAM 23, and an IEEE 139.
It is composed of four blocks 24. I / of this embodiment
The F board 5 uses a PCI bus as an interface in the computer device 3, whereas the F board 5 uses an IEEE 1 in the digital tape recorder 6.
Since 394 is adopted, it is provided to match transmission data between the PCI bus and IEEE1394. For this reason, the I / F conversion processing unit / control unit 22 converts the data in the transmission format corresponding to the PCI bus into packet data corresponding to IEEE 1394, or converts the data in the transmission format corresponding to IEEE 1394 into the PCI bus. Execute the process to convert to the data format. Since the maximum transfer rate of IEEE 1394 is set to 25 Mbps, which is higher than the actual transfer rate of the PCI bus, the data recording / reproducing operation (writing / reading operation to / from the magnetic tape) in the digital tape recorder 6 will be described later. The I / F conversion processing unit / control unit 22 is configured to be able to execute the control for this. The bank RAM 23 is provided for temporarily storing transmission data in order to adjust data transmission timing. In this case, it is assumed that two banks having a capacity of 2 megabytes are provided. The IEEE 1394 block 24 matches the physical layer, transmission timing, and the like for data in packet units corresponding to the IEEE 1394 format.

The digital tape recorder 6 is an IEEE1
394 block 25, data buffer 26, RF processing block 27, mechanical deck mechanism 28, mechanical deck controller 29, and controller 30. IEEE
The 1394 block 25 includes an I / F conversion processing unit / control unit 2
2 has the same configuration as the IEEE 1394 block 24. The IEEE1394 block 25 is an IEEE1 block on the side of the I / F conversion processing unit / control unit 22.
Connected to 394 block 24, up to 25 Mbps
The data can be mutually transmitted at a transfer rate of. Data buffer 26 and RF processing block 27
Then, a process of converting the data in the IEEE 1394 format into a data format suitable for recording on a magnetic tape is executed by required signal processing. Alternatively, a process of converting data reproduced from the magnetic tape into data in the IEEE 1394 format and transmitting the data to the IEEE 1394 block 25 is executed.

In the present embodiment, a control signal relating to recording / reproduction control for the digital tape recorder 6 transmitted from the control unit 11 of the computer device 3 is received.
Based on the control signal, the digital tape recorder 6
It is also configured to execute required control for each functional circuit section in the inside.

<4. Recording / Reproducing Operation on Magnetic Tape in Recording / Reproducing Device> (4-a. Recording Operation) Next, the recording / reproducing operation on the magnetic tape in the digital tape recorder 6 described with reference to FIG. The flow will be described based on the configuration shown in FIG. 3, and the recording operation will be described first with reference to FIG. 4 and FIG. In the following description, the digital tape recorder 6
Will be described on the assumption that the data recorded on the magnetic tape is digital broadcast image data obtained by the unit of the antenna 1 and the receiving board 2, that is, image data compressed by MPEG2.

By the way, if the digital tape recorder 6 of the present embodiment steadily runs a magnetic tape at a normal tape speed to record data, the recording capacity that can be originally recorded on the magnetic tape is as follows. 25M
bps (based on the IEEE 1394 standard), if the recording operation is continued for one hour, as shown by 25 × 60 × 60/8 = 11.25 GB, the maximum is 11.25 GB per hour.
Can be recorded. However, M
In the case of PEG2 image data, the data length is variable, and the data rate varies in a range of about 1 Mbps to 10 Mbps. Therefore, assuming that the magnetic tape is running constantly at a normal tape speed as in the above, 1 Mbp
If s MPEG2 image data is continuously recorded for one hour, only 0.45 GB of data is recorded per hour as represented by 1 × 60 × 60/8 = 0.45 GB. . That is, when the recording data is of variable length and the transfer rate of the data to be recorded is lower than the recording rate of the digital tape recorder, the recording efficiency with respect to the recordable capacity decreases. Therefore, in the present embodiment, when data is recorded in the digital tape recorder 6, the data is recorded by running the magnetic tape at intermittent timing as described below.

When recording image data on the digital tape recorder 6, the computer device 3 sends the image data to the I / F conversion processing unit / control unit 22 in the I / F board 5 via the bus line 21. Image data is transmitted. In this case, the transfer rate of IEEE 1394 is 25 Mbps.
Image data is transferred at a lower transfer rate.

When recording intermittently in the digital tape recorder 6, as described later, real data is recorded in track units, and dummy data is recorded in track units at a predetermined timing. For this reason, the I / F conversion processing unit / control unit 22 converts the transmitted image data into data in packet units corresponding to IEEE 1394, generates the dummy data at a predetermined timing, and also converts the dummy data into IEEE 1394 data. Is performed to convert the data into packet data corresponding to. In addition, a process of adding data serving as an ID for identifying real data and dummy data is performed.

The data output from the I / F conversion processing section / control section 22 through the above-described processing is written and read to and from the bank RAM 23 at a predetermined timing to adjust the data transmission timing. Can be It should be noted that the writing and reading control for the bank RAM 23 is executed by the I / F conversion processing unit / control unit 22. The data read from the bank RAM 23 and adjusted in timing is supplied to the IEEE 1394 block, where the physical layer and the transmission timing are adjusted so as to conform to the IEEE 1394 as described above, and the digital tape recorder 6 side The data is transmitted to the IEEE 1394 block 25.

In the present embodiment, it is possible to give a command relating to the recording / reproducing operation to the digital tape recorder 6 from the computer device 3 side, but a command signal for this is also provided by the computer device 3 side. It is configured to be able to transmit from the bus line 21 to the digital tape recorder 6 via the I / F board 5.

The IEEE inside the digital tape recorder 6
The data transmitted to the 1394 block 25 passes through the data buffer 26 and the RF processing block 27 so that image data (here, real data and dummy data are present) is converted into an RF signal. By supplying the RF signal-converted image data to the rotary head in the mechanical deck mechanism 28, the image data is recorded on the magnetic tape in units of tracks (which are handled as frames in the present embodiment). .

The intermittent recording of data on the magnetic tape is performed as follows based on the above data flow. Here, the I / F conversion processing unit / control unit 2
2 writes data to one bank of the bank RAM 23, and the amount of data stored in this bank reaches a predetermined amount. In accordance with this timing, the I / F conversion processing unit / control unit 22 generates a capstan start control signal to the mechanical deck control unit 29 of the digital tape recorder 6 using, for example, Asynchronous transmission according to IEEE1394. To transmit. This capstan start control signal is transmitted to the IEEE 1394 block 25.
→ From the IEEE 1394 block 24, for example, the control unit 3
0 to the mechanical deck control unit 29.

When the mechanical deck control unit 29 of the digital tape recorder 6 receives the above capstan start control signal, the mechanical deck controller 29 stops the capstan which has been in the stopped state for 0.8 seconds corresponding to the head scan timing for 24 frames. Control is performed on the mechanical deck mechanism 28 so that the mechanical deck mechanism 28 is driven to rotate in the forward direction at a constant speed.

FIG. 4 shows the subsequent recording operation. In this figure, the recording operation is shown by the relationship between the time and the tape speed determined by the rotation speed of the capstan. The time point when the above-described operation of rotating the capstan in the stopped state to rotate in the forward direction at the steady speed is started is t1.
As can be seen from this figure, the period from the time t1 to the time t2 after the capstan driving is started for a while is a rising period until the tape speed reaches a predetermined steady speed. Therefore, in the present embodiment, during the period from t1 to t3, which is the period from the start of driving of the capstan until the tape speed reaches the steady speed and stabilizes,
Dummy data is recorded on a magnetic tape. In this case, the period t1 to t3 is set to 165 msec and corresponds to five frames, so that the recording of the dummy data is first performed over five frames.
FIG. 5 shows a track pattern on the magnetic tape formed corresponding to the recording operation shown in FIG. The digital tape recorder 6 according to the present embodiment
In the description, it is assumed that one track corresponds to one frame period. The recording of the dummy data in the above-described periods t1 to t3 is set to the sections D1 to D3 in FIG. 5, and the dummy data is continuously recorded for five frames (tracks) as described above.

The I / F conversion processor / controller 22
Is the timing suitable for the actual data recording at time t3 shown in FIG.
Is transmitted to the digital tape recorder 6 side. In this case, it is assumed that data for 18 frames is transmitted to the digital tape recorder 6 side.
25 (Mbps) × 0.6 (msec) = 15 (Mbi
t) to be slightly less than 2MB,
It matches the data storage capacity of one bank of M23.

The data transmitted to the digital tape recorder 6 is adjusted in recording timing by a data buffer 26, and then supplied to a mechanical deck mechanism 28 via an RF processing block 27, whereby the data shown in FIG. In the period from t3 to t4, recording on the magnetic tape is performed as actual data over 18 frames (tracks). FIG. 5 shows a state in which the actual data is recorded in the sections D3 to D4.

From time t4 onward, the mechanical deck controller 2
8 shifts to control for stopping the rotation of the capstan. A period t4 during which the rotation of the capstan is assumed to fall due to the rotation stop control of the capstan.
From t5 to t5, dummy data for one frame (track) (33.3 msec) is recorded on the magnetic tape. After that, the rotation of the capstan is completely stopped. In FIG. 5, one frame (track) of dummy data recorded in the sections D4 to D5 corresponds to this. Thereafter, the recording operation shown in the periods t1 to t5 in FIG. 4 is intermittently repeated at a predetermined timing according to the data write / read operation in the bank RAM 23.

As described above, in the present embodiment, when recording the image data in the digital tape recorder 6, the timing at which the data is sufficiently stored in the bank RAM 23 is determined intermittently. The data is transmitted to the digital tape recorder 6, and the digital tape recorder 6 responds to this by
The magnetic tape is intermittently driven to record data. At this time, during the period in which the tape running speed at the time of rising and falling of the capstan is considered to be unstable, recording of appropriate data is realized by recording dummy data, and continuity of frames (tracks) is achieved. Not to be lost. Further, by recording the dummy data at the time of rising and falling of the capstan, even if there is a frame pattern recorded in the past, it can be completely overwritten and erased. It should be noted that the frame pattern shown in FIG. 5 is merely a schematic pattern. In practice, a frame (track) of dummy data recorded at the time of rising and falling of the capstan is formed between adjacent frames (tracks). The intervals are out of order.

(4-b. Reproduction Operation) In the present embodiment, even when recording data is reproduced by the digital tape recorder 6 and transmitted to the computer device 3, the output rate of the reproduction data of the digital tape recorder is also On the other hand, the data transfer rate for transmission to the computer device 3 becomes lower. For this reason, even during reproduction, the digital tape recorder 6 reproduces data by running the magnetic tape intermittently to accumulate reproduction data in the bank RAM 23 of the I / F board 5. Then, by transmitting the data read from the bank RAM 23 to the computer device 3, the computer device 3 can continuously obtain image data via the bus line 21.

The reproducing operation and the transmission path of the reproduced data at this time are as follows. Here, the operation at the time of normal reproduction at normal 1 × speed will be described. At the time of normal reproduction, the capstan motor and the rotary head are driven by the control operation of the mechanical deck controller 29 so that the magnetic tape of the tape cassette TC loaded in the mechanical deck mechanism 28 intermittently runs at a predetermined 1 × speed. Is done.
Here, the magnetic tape is inserted into the mechanical deck mechanism section 28 by one.
Assuming that the rotation of the capstan motor for running at double speed is started, data reproduced from the magnetic tape by the rotating head is supplied to the RF processing block after the start.

The data supplied to the RF processing block 27 is transmitted to the IEEE 1394 block 25 via the data buffer 26, where it is converted into packet data conforming to IEEE 1394, and converted into the IEEE 1394 packet in the I / F board 5.
It is passed to the EE1394 block 24. In the I / F board 5, the data transmitted to the IEEE 1394 block 24 is, for example, an I / F conversion processing unit / control unit 22.
Is real data or dummy data, and if it is real data, writing to the bank RAM 23 is performed. This identification processing is performed by referring to the ID added to the recording data for identifying the dummy data and the actual data described above.

During the reproducing operation on the magnetic tape, the I / F conversion processing unit / control unit 22 controls the I / F
If the data transmitted to the board 5 is identified as dummy data, the I / F conversion processing unit / control unit 2
2 transmits a capstan stop control signal to the mechanical deck control unit 29 of the digital tape recorder 6 using, for example, Asynchronous transmission according to IEEE 1394.
As a result, the rotation of the capstan motor is stopped in the mechanical deck mechanism 28, and the running of the magnetic tape is stopped in the track (frame) area where the dummy data is recorded at the position corresponding to the rotary head. Is controlled.

In the above-described reproducing operation, when the 18-frame actual data described above is stored in one of the banks of the bank RAM 23, the I / F conversion processing unit / control unit 22 transmits the actual data. Is read out and taken in, and transmitted to the computer device 3 via the bus line (PCI bus) 21. Thereafter, the I / F conversion processing unit / control unit 22 returns to the control for starting the magnetic tape to run at a normal speed of 1 ×. By repeating the reproducing operation described so far, the computer device 3 is supplied with the actual data reproduced by the digital tape recorder 6 continuously and alternately from the two banks of the bank RAM 23. . Then, on the computer device 3 side, for example, the supplied data (in this case, M
By performing necessary signal processing including data decompression processing on the image data according to PEG2), the reproduced image can be displayed on the display 3a. Such display processing is performed based on, for example, the image display control program 11b.

<5. Data Structure of Management Information> In order for the digital tape recorder 6 to properly perform recording / reproduction of image data on the tape cassette TC, a management in which information such as the recording history of the magnetic tape of the tape cassette TC so far is stored. Information (hereinafter referred to as TOC (Table
It is necessary for the computer device 3 or the digital tape recorder 6 itself to execute various control operations related to the recording / reproducing operation with reference to the management information. In the present embodiment, the TOC as described above is created by the processing of the control unit 11 on the computer device 3 side and stored in the internal storage device 13.

FIG. 6 shows an example of the structure of the TOC in this embodiment. The TOC shown in this figure is created for each file. The term "file" used herein refers to, for example, a data group recorded from the start of recording on the magnetic tape to the end of the recording operation by a stop operation, as a unit recorded on the magnetic tape, for example. Each time one file is recorded on the magnetic tape by the digital tape recorder 6, the TOC shown in this figure is created and stored.

In the TOC shown in FIG. 6, for example, a cassette ID area A1, a file ID area A2, a recording start track number area A3, a recording end track number area A4, a file name area A5, and a recording date and time area A6 are provided. The cassette ID area A1 is formed of 8 bits. In order to identify a tape cassette TC in which a file corresponding to the TOC is recorded, a cassette I set differently for each tape cassette TC is set.
This is an area where D is stored. In the present embodiment,
For example, on the tape cassette TC side, a cassette ID is recorded together with image data in a predetermined format on each track of the magnetic tape. Alternatively, it has been previously proposed by the present applicant to provide a memory element on a tape cassette and store recording history information of recording data in the tape cassette for the memory element. It is also conceivable to store the cassette ID. Thus, the digital tape recorder 6 reproduces the magnetic tape or reads the data stored in the memory element, so that the computer device 3 identifies the tape cassette TC on which the magnetic tape is wound based on the cassette ID. It is possible.

The file ID area A2 is an area for storing a file ID set differently for each file, and is formed by 8 bits.
