2. Description of the Related Art Conventionally, a digital VTR for recording and reproducing an image signal as a digital signal on a magnetic tape has been known. In recent years, the HD Digital VCR Council has proposed the DV format as the format of a consumer digital VTR.

[0003] In the DV format, an NTSC image signal is recorded on ten tracks per frame.
Specifications (hereinafter SD mode) and SD high compression specifications (hereinafter SDL) to be recorded on 5 tracks per frame
Mode) is defined. In the SDL mode, the information amount of the data to be recorded is set to about の of that in the SD mode, so that the transport speed of the tape is set to の of that in the SD mode, and one frame of data is recorded on five tracks. The recording time can be made twice as long as in the SD mode by the length. An apparatus for recording image data in the SD mode and the SDL mode is disclosed in, for example, Japanese Patent Application Laid-Open No. 11-328.
No. 639.

FIG. 1 shows an example of the configuration of a magnetic head in a digital VTR compatible with both the SD mode and the SDL mode. In the SD mode, recording is performed by alternately switching between a magnetic head indicated by Ach having a positive azimuth angle and a head indicated by Bch having a negative azimuth angle arranged at a position opposite to Ach by 180 °. , Play. In the SDL mode, a magnetic head indicated by Bch having an azimuth angle of-and a position 270 ° delayed from the Bch by a drum rotation direction angle +

The height in the drum rotation axis direction differs from the h head in accordance with the phase difference.

FIG. 2 is a diagram showing a use state of each head shown in FIG. 1 and a state of output when data recorded in the SD mode is reproduced in the normal reproduction mode.

FIG. 2A shows a switch pulse for switching between the Ach head and the Bch head, which is a signal generated by a PG signal indicating the rotation phase of the rotating drum and having one cycle for one rotation of the drum. While the SWP is at the high level, the output of the Ach head is selected, and when the SWP is at the low level, the output of the Bch head is selected.

FIG. 2B shows the state of the head in contact with the magnetic tape. The period in which the Ach and Bch magnetic heads are in contact with the magnetic tape is indicated by a solid line, and the period in which the magnetic heads are not in contact with the tape is indicated by a dotted line. Are indicated by.

FIG. 2 (b) shows a mute pulse signal. The signal level of the SWP changes because the Ach head and the Bch head suppress noise signals generated near the start and end of the tape trace. High level in the vicinity.

FIG. 2D shows the RF output from each head.
FIG. 2A shows the state of the signal.
The output from the magnetic head Ach or Bch in contact with the magnetic tape is a signal selected by the mute pulse of (c).

On the other hand, FIG. 3 shows a state in which data recorded in the SDL mode is reproduced in the normal reproduction mode.
FIG. 3 is a diagram showing a use state of each head shown in FIG.

FIG. 3A shows a switch pulse for switching between the Bch head and the Cch head, which is a signal generated from the PG signal and having one cycle for two rotations of the drum.
The output of the Cch head is selected when the SWP is at the high level, and the output of the Bch head is selected during the low level.

FIG. 3B shows the state of the head in contact with the magnetic tape. The period in which the Bch and Cch magnetic heads are in contact with the magnetic tape is indicated by solid lines, and the period in which the Bch and Cch magnetic heads are not in contact with the tape. Are indicated by dotted lines.

FIG. 3C shows a mute pulse signal.
Once every two rotations of the drum, the reproduction signal of the Bch head or Cch head is output only for a specific period.
This is a signal for controlling a noise signal generated near the start and end of the tape trace by the ch head and the Bch head.

FIG. 3D shows a Bch head and a Cch head.
2 shows an RF signal output from a head. In the SDL mode, the information amount of the signal to be recorded is reduced to half of that in the SD mode.
When the tape transport speed is set to 1/2 of that in the SD mode and one track is formed by one rotation of the drum, a recording track having the same pitch as that in the SD mode is formed on the magnetic tape. Therefore, the head output signal shown in FIG. 3D is generated by the magnetic head Bch or the magnetic head B in contact with the magnetic tape by the SWP and the mute pulse.
The output signal is a signal that makes one round with two rotations of the drum obtained by selecting the output from Cch.

[0015]

In a conventional VTR such as an 8 mm system, slow-motion reproduction can be realized by transporting a tape at a speed lower than a tape feeding speed at the time of recording. When performing slow playback of data recorded in the SD mode, SWP is generated in the same manner as in the normal playback mode, and the tape is conveyed at a speed lower than the tape feed speed at the time of recording. The trajectories do not match,

However, in this case, as is apparent from FIG. 4D, the output signal level reproduced from the tape is significantly reduced depending on the mounting position of the head and the like. Therefore, even when the memory is used, there is a problem that one frame of image data is partially lost, the entire reproduction screen cannot be continuously updated, and block noise occurs.

An object of the present invention is to solve the above-mentioned problems.

First, in step S801, based on the mode information output from the reproduction processing circuit 603, the signal recorded on the track traced by the magnetic head is recorded in the SD mode or recorded in the SDL mode. Is determined.

If it is determined that the mode is the SDL mode,
In step S802, the reproduction mode designated by operation key 610 is determined. If the playback mode is not the slow motion playback mode, at step S803,
Mode information indicating the normal reproduction mode in the SDL mode is output to the WP generator 608 and the servo circuit 611.

Then, the SWP generator 608 is used as shown in FIG.
7 is generated and output to the switch 714 in FIG. 7 to perform control according to the normal reproduction mode of the SDL mode shown in FIG. Also, the servo circuit 61
1 controls the rotation of the capstan so that the tape T is transported at the normal speed in the SDL mode.

If it is determined in step S802 that the playback mode is the slow motion playback mode, the process proceeds to step S802.
At 804, the SWP generator 608 and the servo circuit 61
For mode 1, mode information indicating the slow reproduction mode of the SDL mode is output. The SWP generator 608 performs control according to the slow reproduction mode of the SDL mode as described later according to the mode information, and the servo circuit 611 intermittently controls the magnetic tape T at an average speed lower than the normal speed of the SDL mode. Capstan 61 to transport
2 is controlled.

If it is determined in step S801 that the signal recorded on the track being traced by the magnetic head is in the SD mode, then in step S805, the reproduction mode specified by the operation key 610 is determined. I do.

If the reproduction mode is not the slow-motion reproduction mode, at step S806, the SWP generator 6

The P generator 608 generates a switch pulse of 150 Hz shown in FIG. 2A and outputs it to the switch 710, and performs control according to the normal reproduction mode of the SD mode shown in FIG. Further, the servo circuit 611 controls the capstan 6 so that the magnetic tape T is transported at the normal reproduction speed in the SD mode.
12 is controlled.

If it is determined in step S805 that the playback mode is the slow motion playback mode, step S805 is executed.
At 807, the SWP generator 608 and the servo circuit 611
Output mode information indicating that the mode is the slow playback mode of the SD mode. The SWP control circuit 608 generates a switch pulse of 150 Hz shown in FIG. 2A and outputs it to the switch 710, and generates a mute signal shown in FIG. 2C and outputs it to the switch 715.
As in the normal reproduction mode, a switch pulse is generated and output to the switch 714 so that the D terminal is always selected. The servo circuit 611 controls the capstan 612 so as to intermittently transport the magnetic tape T at an average speed lower than the normal reproduction speed in the SD mode.

Next, slow motion control for intermittently transporting the tape will be described. FIG. 9 is a timing chart showing the state of capstan drive control when data recorded in the SD mode is played back in slow motion.

For example, when data recorded in the SD mode is played back in slow motion at 1 / 5-fold speed, the tape is set to a speed of 1/3 of the speed in the recording in the SD mode for a period corresponding to 15 rotations of the drum indicated by 901. The microcomputer 609 outputs a control signal as shown in FIG. 9B to the servo circuit 611 so as to stop the transport of the tape during the period corresponding to the rotation of the drum 10 indicated by 903. And
In this tape transport period 901, data of one frame is reproduced from ten tracks on the tape T using the Ach head and the Bch head of FIG. For example, if the tape transport speed at the time of recording in the SD mode is V, in the transport period 901, V / 3
The tape T is transported at a speed of.

In this embodiment, since five rotation periods of the drum 601 correspond to one frame period, 901 and 903 in FIG.
Is equivalent to five frame periods. By reading the data of one frame reproduced in the five-frame period from the track memory 604, 1/5 speed slow-motion reproduction is realized.

On the other hand, FIG. 10 is a timing chart showing how to control the driving of the capstan when the data recorded in the SDL mode is reproduced at a 1/5 speed in slow motion.

In the SDL mode, when performing slow-motion playback at 1/5 speed, the drum 15
During the period corresponding to the rotation, the tape T is transported at a speed 2/3 that of the time of recording in the SDL mode, and the drum 35 indicated by 1003 is rotated.
To stop the transport of the tape T for a period corresponding to the rotation,
The microcomputer 609 controls the servo circuit 611 in FIG.
The control signal shown in (b) is output. For example, assuming that the tape transport speed at the time of recording in the SDL mode is V / 2, the tape T is transported at a speed of V / 3 in the transport period 1001, which is V / 2 × 2/3.

In this embodiment, as described above, the drum 601
10 corresponds to one frame period.
Period 1001 corresponds to a 5-frame period. And
Since the tape T is conveyed at a speed 2/3 that of the SDL mode during the drum 15 rotation period, the period 100
In 1, the data of two frames in total is reproduced from the tape T and written into the track memory 604.

Also, since the drum 50 rotation period obtained by adding 1001 and 1003 in FIG. 10 corresponds to 10 frame periods, the data read from the track memory 604 is read in FIG.
0 (c), the first five frame periods 1005
By switching between the five-frame period 1007 and the latter half, 100% slow-motion reproduction is realized.

Next, the slow motion reproduction in the SDL mode will be described in detail.

FIG. 5 shows output signals of the main blocks in FIG. 6 during slow motion reproduction in the SDL mode.

SWP shown in FIG. 5A indicates the control state of the head switching circuit 602. The head switching circuit 602 selects the output of the Ach head having a + azimuth angle on the rotating drum 601 during the period when the SWP is at the high level, and selects the output of the Bch head having the -azimuth angle during the period when the SWP is at the low level. That is, in this embodiment, the Ach head and the Bch head for the SD mode are used instead of the Bch head and the Cch head for the SDL at the time of the slow reproduction in the SDL mode.

FIG. 5D shows the state of an output signal selectively output from the head switching circuit 602 during a tape transport period during slow motion reproduction, here, a period 1001 in FIG. Then, the reproduction processing circuit 60
Reference numeral 3 detects the synchronization and ID data in each sync block from the output data of each head reproduced in this way, and writes the data of each sync block to an address of the track memory 604 corresponding to each ID data.

As shown in FIG. 5D, Ach, Bc
In the output signal from the magnetic head h, a period in which an output signal is not sufficiently obtained every one drum rotation occurs, but in this embodiment, the SDL mode in the tape transport period 1001 during slow motion reproduction shown in FIG. 2 at the time of recording
Since the tape is transported at a speed of / 3, the magnetic head traces one recording track three or more times.

Therefore, for the track memory 604,
Most of the data recorded on each track can be stored. As described above, in the slow motion reproduction in the SDL mode, data for two frames is accumulated in the track memory 604 during the period 1001 in FIG. Then, the reproduced data stored in the track memory 604 is switched and read out every five frame periods.

In the period 1005 of FIG. 10, the data of the first half of the two frames of reproduced data reproduced in the immediately preceding transport period 1001 and stored in the track memory 604 is repeatedly read out for each frame. Period 1
In 007, the data of the latter one frame is repeatedly read for each frame.

As described above, according to this embodiment, in the device for recording and reproducing data in the SD mode and the SDL mode with the head shown in FIG. 1, when performing the slow reproduction in the SDL mode, the CDL head for the SDL is used. , An Ach head for SD mode is used, the tape is transported at a slower speed than during recording during the tape transport period to reproduce the data, and the reproduced data is stored in the track memory.
Since the data for the frame is obtained, a reproduced image without noise can be obtained even when the data recorded in the SDL mode is reproduced slowly.

In this embodiment, during slow playback in the SDL mode, during the transport period, two frames of playback data are played back at once, stored in the track memory, and then transport is stopped. 1 compared to mode
S in which the number of tracks for recording frame data is half
Even when data in the DL mode is slow-reproduced by the intermittent driving method, the load on the mechanism such as the capstan can be reduced.

In the above-described embodiment, the image data is recorded on 10 tracks per frame in the SD mode, and the image data is recorded on 5 tracks per frame in the SDL mode. Also, the image data recorded in the mode of recording the image data on 2n tracks per frame (n is an integer of 1 or more) and the mode of recording the image data on the n tracks per frame are reproduced. In this case, the present invention can be similarly applied.

Also, in the case of performing slow playback by intermittent driving, in the SD mode, 1
In the SDL mode, two frames of image data are reproduced in the transport period 1001 in FIG. 10. In addition, m frames (m is an integer of 1 or more) and Data of 2 m frames or any other frame may be reproduced during the transport period.
