[1] Overall Structure FIG. 1 shows a tape cassette equipped with a memory according to the present invention.
As shown in, the magnetic tape cassette 61, which is a recording / reproducing medium, has at least the length of the magnetic tape wound inside the tape cassette 61, the maximum recording time, and the like in addition to the magnetic tape that is a recording / reproducing medium. Is a memory-in-cassette (MIC) having a memory 40 for storing the tape information consisting of and the position information based on the video / audio signals recorded on the tape, and a communication terminal 39a for communicating with the memory 40 Must be provided.

On the other hand, on the side of the recording / reproducing device 61A, at least the memory 4 mounted on the magnetic tape cassette 61.
A communication terminal 39b for recording tape information and position information based on video / audio signals recorded on the tape, a microcomputer 38a as a communication control circuit, and another microcomputer 34a are required in 0. is there.

The tape cassette 6 having such a structure
When 1 is attached to the recording / reproducing apparatus 61A, first, the communication terminal 39a on the tape cassette 61 side and the communication terminal 39b on the recording / reproducing apparatus 61A are connected to each other, and the memory 40 is supplied with power so that communication can be performed.

Although not shown in the figure, the microcomputers 38a, 3a, 3b, 3c, 3c, 3c, 3c, 3c, 3d, 3c, 3d, 3c, 3c, 3d, 3d, 3d, 3d, 3d, 3d, 3d, 3d, 3d
4a is driven to operate the communication control circuit, and the communication terminal 39
Recording / reproducing control signals and data are transmitted / received from b to the communication terminal 39a of the tape cassette 61.

This data transmission / reception is a so-called serial communication system, and it is considered that communication is performed with a minimum configuration. The details of the communication system and the configuration of the cassette equipped with the memory are described in Japanese Patent Application No.
173689, Japanese Patent Application No. 4-217502, etc.).

For example, in the present embodiment, when the tape cassette 61 and the recording / reproducing apparatus 61A are in a communicable state, the contents of the tape information and the position information written in the memory 40 of the tape cassette 61 are first read. , RA installed in the microcomputer 34a on the recording / reproducing apparatus 61A side
It is read by M.

Based on the tape information and the position information read in the RAM, the reproduction control information is created by operating the operation button group of the recording / reproducing apparatus 61A and written in the RAM.

The written tape information in the RAM,
The position information and the reproduction control information are returned to the memory 40 of the tape cassette 61 via the communication control circuit 38a, and the contents of the memory 40 are updated and rewritten.

The problem here is the tape cassette 6
This is the maximum recording capacity of the memory 40 installed in the memory 1. If the maximum recording capacity of the memory 40 is sufficient for recording tape information, position information, and reproduction control information, no problem will occur.

However, in order to increase the recording density of the video / audio signals recorded on the tape to maximize the recording capacity and to reduce the size of the cassette body, the tape cassette 61 is inevitable. There is a limit to the physical space of the memory 40 mounted on the disk and the maximum recording capacity of the memory element.

Therefore, the present problem cannot be achieved unless the limited memory capacity is used as efficiently and effectively as possible. Therefore, by devising the data structure to be recorded in the memory 40, the recording area can be used most efficiently and effectively. The present invention can be achieved by constructing on the basis of a possible structure. still,
The recording side circuit and the reproducing side circuit relating to the recording / reproducing apparatus 61A will be described later in detail with reference to FIGS. 34, 35 and 36.

[2] Pack Structure Next, in this embodiment, a data structure of various applications is constructed by the recording format shown in the prior application (Japanese Patent Application No. 4-325618) of the same applicant, that is, the pack structure. To do.

(1) Structure of Pack First, the pack structure has an area of accompanying data of a video signal recorded / reproduced simultaneously with an audio / video signal and an area of accompanying data of an audio signal recorded / reproduced simultaneously with an audio signal. The basic structure consists of auxiliary data areas, and the structure of each area is composed of a fixed-length pack of 5 bytes.

As shown in FIG. 2, the fixed-length pack of 5 bytes has the first byte (PC0) as item (ITEM) data indicating the content of the data.

Then, a format of 4 bytes (PC1 to 4) following the item (ITEM) data is determined, and arbitrary data is set according to the format.

On the other hand, this item (ITEM) data is divided into upper and lower 4 bits, and the upper 4 bits are called large items and the lower 4 bits are called small items.

The large item is used, for example, as data indicating the purpose of the subsequent data, and the small item is used, for example, as data indicating the specific content of the subsequent data.

Here, the large items are as shown in FIG.
Up to 16 ways can be provided. In addition, a structure is provided in which a maximum of 16 small items can be provided for each large item.

For example, control (0000), title (0001), chapter (0010), part (0011), program (0100), line (01)
01), image auxiliary data (0110), audio auxiliary data (0111), soft mode (1111), etc., and (1000) to (1110) are portions left for addition.

The large item of control (0000) includes the tape ID (000) and the tape length (00
01), timer recording designated date (0010), timer recording start and end time (0011), text control (1000), text (1001), and other small items. Other large items (0001) ~ (11
11) small items (0000-111)
1) is appropriately provided.

In the data structure constructed by such a pack structure, the large items of the control (0000) and the small items are (1010) and (1011).
Can be used to represent the reproduction control information.

Here, the reproduction control information is created based on the position information of the video / audio signals recorded on the tape.

The pack structure storing this reproduction control information is, as shown in FIGS. 4 and 5, an item (ITEM).
Is a large item of control (0000), and (1010) and (1011) are used as small items.

Large item (0000), small item (1
The pack structure (010) stores time code information when a so-called tag is driven by operating an operation button group (not shown) provided in the recording / reproducing apparatus.
That is, the time code information is composed of the time representing the position of the tape when the tag is driven.

On the other hand, the pack structure of the large item (0000) and the small item (1011) has "TRACK NO." Information when the tag is imprinted, the meaning of the tag, such as "TAG" indicating an index, a photo marker, or the like. I
D "information, operation of the recording / reproducing apparatus, eg, repetitive reproduction,
It is composed of "TAG CONT" information designating skip or the like. These two packs are track numbers. When the recording format has a small item (101
Using the pack of 1), track No. A pack of small items (1010) is used for a recording format that does not have a.

A pack structure in which the name of each tag can be entered is also prepared in advance, and information consisting of these tag names is displayed on the screen as shown in FIG. 6, for example, "TAG name" and "time code". By displaying "", the user can immediately select an arbitrary editing position.

[2] Control by Reproduction Control Information (1) Printout Next, the printout by the printout information of the reproduction control information will be described with reference to the flow chart shown in FIG.

First, the tape cassette to be printed out is mounted in the recording / reproducing apparatus so that it can be reproduced (S
T1).

Then, the operation buttons on the recording / reproducing apparatus side are operated to bring the screen to be printed out into a still image state (S
T2).

A tag is entered on the screen in the still image state to be printed out. The entry of this tag is
It is performed by a group of operation buttons on the recording / reproducing apparatus side (ST
3).

When this tag is entered, the reproduction control information is created, and the RA inside the microcomputer in the recording / reproducing apparatus is created.
The contents of M are rewritten. The contents stored in the memory 40 of the tape cassette when the tape cassette is loaded in the recording / reproducing apparatus are recorded in this RAM.

This operation is repeated until all the tags have been hit. That is, the "time code" information and "TRACK NO." Information when the tag is driven are written in the RAM in the form of a pack structure that constitutes the reproduction control information. The reproduction control information rewritten on the basis of the entered tag is sent to the memory 40 of the tape cassette via the communication control circuit 38, and the content in the memory 40 is updated.

Until the typing of all tags is completed,
This operation is repeated (ST4 → ST2).

When all the tags have been entered, as shown in FIG. 6, the "TAG name" to be printed is selected from the reproduction control information displayed on the screen (ST5).

In this state, by pressing the photo button in the operation button group on the recording / reproducing apparatus 4 side, the photo marker information is added to "TAGCONT" in the pack structure "TAGID" of the selected "TAG name". The still image reproduction instruction information is written in ", and via the communication control circuit 38a,
The contents of the memory 40 of the tape cassette are rewritten (ST6, ST7).

At the same time, "TR" of the selected reproduction control information
ACK NO. The track number is searched and detected based on the information, and the still image state is set. Then, the screen in this still image state is printed out (ST8).

In this way, since all the reproduction control information is stored in the memory 40 of the tape cassette, even when the tape cassette is ejected and attached to another editing device, the above-mentioned diagram is used. It is possible to print out simply by selecting the "TAG name" displayed on the screen shown in FIG.

(2) Skip reproduction As will be described later, in addition to the photo marker information, the position where the tag is imprinted is searched for and reproduction is started from that position. A plurality of video / audio signals recorded above can be repeatedly reproduced or skipped (SKIP).

That is, as shown in FIG. 8, control such as skip (SKIP) reproduction, repetitive reproduction, reproduction speed control, program reproduction, etc. can be performed based on reproduction control information. First,
The contents of the memory 40 in the tape cassette are analyzed to search for reproduction control information (ST10).

If the pack structure of the reproduction control information (large item is (0000), small item is (1010), (1
011)), the small item (1011)
According to the contents of "TAG CONT" of No. 1, it is judged whether skip reproduction, repeated reproduction, reproduction speed control or program reproduction (ST11, ST12, ST13, ST1
4). In addition, although each of the embodiments has been described, the reproduction can be performed by appropriately combining them.

In the case of skip reproduction, fast-forwarding is performed until the next reproduction control information is found, and reproduction is performed at the normal speed from the time the reproduction control information is detected (ST11 → ST1).
5 → ST16 → ST17).

In this way, by selecting the video / audio signals recorded on the tape and playing back only the extracted video / audio signals at the normal speed, only the necessary reproduction information can be reproduced. Can be reduced.

(3) Repeated reproduction In the case of repeated reproduction, after reproduction control information is detected, reproduction is repeated until the next reproduction control information is detected. If the stop key is pressed during this time, it will stop. If the next reproduction control information is detected without pressing the stop key, the reproduction is performed again by rewinding to the position designated by the previous reproduction control information. This reproduction is repeated until the stop key is pressed (ST12 → ST18 → ST19 → ST20 → ST2.
1 → ST22).

In this way, by repeatedly reproducing and rewinding the section defined by the reproduction control information,
The same video / audio signal can be played back repeatedly.

(4) Reproduction speed control In the case of reproduction speed control, the reproduction speed amount is read from the reproduction control information and sent to the recording / reproducing apparatus. The recording / reproducing device
The reproduction speed can be set according to the reproduction speed amount (ST13 → ST23 → ST24).

In this way, the slow speed and high speed can be freely set only for the video / audio signals extracted by selecting the video / audio signals recorded on the tape.

(5) Program reproduction In the case of program reproduction, "TAG N" of reproduction control information is used.
O. "Playback can be performed in order based on the information (S
T14 → ST25).

This is as if a continuous video / audio signal was obtained by selecting video / audio signals recorded on the tape in a scattered manner and skipping or rewinding the extracted video / audio signal. It is something that can be played back.

(6) Voice / image quality control As shown in FIG. 9, voice / image quality control, editing control, and environment control can be performed based on the reproduction control information.

That is, the content of the memory 40 in the tape cassette is analyzed and the reproduction control information (large item (0000),
In the case of small items (1010) and (1011), audio / image quality control, editing control, and environmental control are performed according to the contents of "TAG CONT" of the small item (1011) (ST26, ST27, ST28, ST2
9). It should be noted that these can be appropriately combined, and the above (2) to (5) can also be appropriately combined.

In the case of voice / image quality control, it is possible to freely control the volume of the voice based on the information secured in advance in the data area of the small item (1011), or the blurring by changing the image quality. It is a thing (S27 →
S30).

Therefore, the video recorded on the tape
It is possible to freely set the video / audio signals by blurring the screen of the video / audio signals extracted by selecting the audio signals and reducing the sound.

(7) Editing control In the case of editing control, a small item (101
Depending on the contents of "TAG CONT" in 1), you can freely control the stop and playback of other editing equipment (ST28 → ST
31). By being able to carry out such control, it becomes possible to extract only the desired video / audio signals at the time of dubbing, for example.

(8) Environmental control In the case of environmental control, a small item (101 of reproduction control information)
Based on the content of "TAG CONT" in 1), by interlocking the lighting device and the speaker device surrounding the recording / reproducing device, for example, the lighting is dim to enhance the sense of presence and the deep bass sound of the speaker is increased. It can be controlled freely (ST29 → ST32).

[4] TAG Pack and ZONE END Pack Next, the TAG pack and the ZONE END pack used in the tape cassette having the memory according to the present invention will be described with reference to the drawings. That is, a TAG pack and a ZONEEN as the fixed length pack of 5 bytes described above.
The D pack is provided, the position information of the start point of the zone is stored in the TAG pack, and the position information of the end point of the zone is stored in the ZONE END pack.

When information of a certain section on the tape (hereinafter referred to as ZONE) is stored in the memory, a TAG pack (header = 0Bh) and a ZONE END pack (header = 0Fh) are used as a pair.

Here, the signal recorded for each track on a tape mounted on a recording / reproducing apparatus which is a digital VCR has a function of recording a subcode signal in addition to a video signal and an audio signal. It is a thing.

That is, by providing the area for recording the sub-code, the positional information of the two points on the tape and the reproduction control information between these two points are stored in the memory of the cassette and at the time of recording on the tape. By recording the subcode also on one track, it is possible to control certain information even in a tape cassette having no memory.

[5] Subcode FIG. 10 shows a format of a track of a recording / reproducing apparatus which is a digital VTR applied to the present invention and a partially enlarged view thereof. As shown in this figure, in the digital VTR, the ITI area, the audio area, the video area, and the subcode area are recorded in this order from the track entrance side.

Here, the ITI is a timing block for accurately performing positioning during post-recording, and is used for the 1400-bit preamble for PLL run-in during signal reproduction, and the above-mentioned positioning during post-recording. SSA (Start Sync Block Ar)
ea), APT (Application I) that is 3-bit ID data that defines the data structure on the track.
TIA (Trac including D of a Track) etc.
k Information Area) and a postamble.

Further, both the audio area and the video area are provided with a preamble consisting of run-up and pre-SYNC and a postamble consisting of post SYNC and a guard area before and after the audio area and the video area.

The subcode area is an area provided mainly for recording information for high speed search, and is shown in FIG.
As shown in Figure 12, 12 S with a data length of 12 bytes
A YNC block is included, and a preamble and a postamble are provided before and after the YNC block. However, unlike the audio area and the video area, the pre-SYNC and the post-SYNC are not provided.

As described above, after the data is recorded in the audio area and the video area, the data is also recorded in the sub code area. This subcode area is composed of a data section and an ID section.

The data section is, as shown in FIG. 11, 0 to 1
Five bytes are written in each of the first SYNC blocks, and each pack forms one pack. That is, 12 packs are recorded in one track, of which the 3rd to 5th and 9th to 11th packs form a main area, and the other packs form an optional area. In the NTSC system, 10 tracks form one frame.

The contents of data recorded in the main area are different between the first half 5 tracks and the latter half 5 tracks in one frame. That is, as shown in FIG. 12, the first half 5
In a track, a TTC (Title Time Code) or its BIN (Title Time Code Bin) indicating the position where the title of the recorded content is recorded
ary group) pack is recorded, whereas in the latter half 5 tracks, REC is recorded outside the TTC pack.
DATE pack and REC TIME pack are recorded.

In these packs, the same data is repeatedly recorded in the first half and the latter half of the five tracks, and the positions of the third to fifth SYNC blocks and the positions of the ninth to eleventh are repeatedly recorded in the same track. It has become so.

As shown in FIG. 13, A and C represent TTC data, B represents TTC or BIN data, and D represents RE.
CDATE data, E represents REC TIME data.

Further, a, b, c, ..., K, and m represent pack data of the optional area, and data of 6 packs is 5 in the first half and the latter half of one frame, respectively.
The recording position is repeatedly recorded, and the recording position is switched for each track.

The recording pattern of the sub-code of one frame when recording a PAL video signal is shown in FIG.
As shown in, one frame consists of 12 tracks,
The subcode on one track is composed of 12 SYNC blocks. The data in the main area and the optional area are repeatedly recorded, and the pattern is the same as in the NTSC system.

As shown in FIG. 11, the subcode data has only a 2-byte horizontal parity C1 having a short byte length, and no vertical parity. Therefore, the tape protection ability by parity is weaker than the case of audio data or video data, but as described above, by repeatedly recording the same data many times, it is possible to reproduce by using the majority decision at the time of reproduction. The reliability of data can be improved. Further, since the data is repeatedly recorded at different positions on the track, there is a high possibility that the data can be read even when the tape is laterally scratched.

Next, as shown in FIG. 15, the ID part is I
An F / R flag is provided in the most significant bit of D0 and indicates whether or not it is the first half 5 tracks of the frame. The first half 5 tracks have a value of "0", and the second half 5 tracks have a value of "1".

In the next 3 bits, AP3 which is an ID signal defining the data structure of the subcode area is recorded in the SYNC blocks whose SYNC block numbers are "0" and "6", and the other SYNC is recorded. A TAG code is recorded in the block. However, the area with the SYNC block number “11” is a spare area.

The TAG code is three types of IDs for searching.
It is composed of INDEX ID, SKIP ID, and PP ID (Photo / Picture ID) which are signals. The same contents of the TAG code are written in the TAG pack stored in the memory of the cassette described later. That is, by recording the minimum required information in the subcode area and the memory of the cassette, it becomes possible to control the tape with the minimum information even if the cassette does not have a memory. ing.

The minimum necessary information in this embodiment is I
These are NDEX ID, SKIP ID, and PP ID.
The control by the INDEX ID is used, for example, in the case of designating a heading portion in a moving image or in designating a still image.
The control based on the SKIP ID is used, for example, when skipping the video recorded on the tape to obtain continuous video. The control by the PP ID is used, for example, when a still image and a moving image recording are mixed and a high speed search is performed by designating an arbitrary still image.

The absolute number of the track (the continuous track number from the beginning of the tape) is recorded using the lower 4 bits of ID0 and the upper 4 bits of ID1. However, the absolute number of this track is 2 for a total of 3 SYNC blocks.
One absolute track number is recorded using 4 bits.

The SYNC block number of the sub code area is recorded in the lower 4 bits of ID1. IDP is I
It is the protection parity of D0 and ID1.

The subcode area having such a structure has various advantages. For example, the SYNC block is shortened to record information a number of times in a subcode of one track, and the parity protecting the data part is composed of only horizontal parity that does not take a product code structure, so that it is about 200 times. High-speed search up to is possible. Regarding the compatibility of rewriting of the data part, REC DATE and REC TIM that are highly likely to be rewritten
Since E is recorded only in the latter half of the frame, the rewriting operation can be easily performed. The F / R flag of the subcode information makes it easy to discriminate the data in the first half and the second half of the frame.

Further, the subcode ID signal (INDEX
Still images can be recorded by using ID, SKIP ID, PP ID). For example, snap recording by repeatedly recording one frame image on the tape for several seconds, so-called strobe recording by repeatedly recording on the tape until one frame image signal image is extracted every several frames. You can In addition, single-shot recording, continuous single-shot recording, etc. are possible.

Even with a tape in which such a still image recording portion and a normal moving image recording portion are mixed, the above-mentioned I
Using the NDEX ID, SKIP ID, and PP ID, it is possible to quickly find the start of an arbitrary still image or moving image, skip unnecessary recording parts, search for a specified still image, and the like.

In order to control the reproduced recording between the position information of two points of the tape using the TAG pack and the ZONE END pack stored in the memory of the cassette of the present invention, a track is provided with a subcode for searching. It is premised that etc. can be performed at high speed.

[6] Structure of TAG pack In the TAG pack consisting of items = OBh, as shown in FIG. 10, each of PC0 to PC4 is composed of 8 bits.
It has a bite structure.

PC0 represents an item (header), and item = OBh. PC1 indicates the lower 7 bits of the absolute track number, PC2 indicates the middle 8 bits of the absolute track number, and P
C3 indicates the upper 8 bits. The absolute track number is represented by 23 bits in total.

The PC 4 forms the TAG ID in the lower 4 bits, and forms the TEXT flag in the most significant bit.

The TAG ID is a combination of 4 bits, and is used as a ZON END pack in combination with ZON.
It is identified whether E is designated or a point on the recording medium is designated. That is, the lower 4 bits are 0000 = INDEX,
0001 = SKIP START, 0010 = PP (P
HOTO PICTURE), 0101 = STILL,
When 0110 = FREEZE, one point on the recording medium is designated.

The lower 4 bits of PC4 are 0011 = P
ROGRAM PLAY START, 0100 = ZO
In the case of NE PLAY (indicating the starting point of ZONE), ZONE is designated. Furthermore, 1000 =
DATE CHANGE, 1001 = TIME CHA
Specify NGE, 1100-1111 = RESERVE
Has been D. Each of these reproduction methods will be described later.

[7] Structure of ZONE END Pack The ZONE END pack consisting of items = 0Eh is
As shown in FIG. 11, each of PC0 to PC4 is composed of 5 bytes of 8 bits, like the TAG pack described above.

PC0 represents an item, and if item = 0Fh, it is a ZONE END pack, and P0
The absolute track number, which is composed of a total of 23 bits of C1, PC2, and PC3, stores one piece of ZONE end point information.

The PC4 is a TAG composed of 8 bits.
CONT (TAG CONTROL) is represented, and TAG CONT stores reproduction control information between position information of two points of the recording / reproducing apparatus, and its upper 4
Various functions can be realized by the bit configuration.

1 if the upper 2 bits are "01"
It is a function to play only once. When the upper 2 bits are “10”, this is a function of performing repeated reproduction only once. When the upper 2 bits are "11", this is a function of continuing the repeated reproduction until something is input.

Further, special reproduction of the high-order 2 bits of "01", "10", and "11" shown in the above items, that is, special reproduction, is performed after the high-order 2 bits.
3 bits of DE (FORWARD MODE), RMO
3 bits of DE (REVERSE MODE) follow.

FMODE indicates how to reproduce in the forward rotation direction, and "000" = No OPERATION (no operation) "001" = PLAY (normal reproduction) "010" = SLOW (slow reproduction) “011” = CUE (fast forward playback) “100” = FF (fast forward) “101” = STOROBE (strobe playback) “110 to 111” = RESERVE (standby).

RMODE indicates how to reproduce in the reverse direction, and "000" = NO OPERATION (no operation) "001" = REVERSE PLAY (reverse reproduction) "010" = REVERSE SLOW (reverse slow) Playback) "011" = REVIEW (rewind playback) "100" = REWIND (rewind) "101" = REVERSE STOROBE (reverse strobe playback) "110-111" = RESERVE (reserve).

[8] TAG pack and ZONE END
Usage of the pack The TAG pack and the ZONE EN configured in this way
A case where the information of a certain section (ZONE) of the tape is stored in the memory by using the D pack will be described with an example.

First, the position information of the ZONE start point is stored in the absolute track numbers of PCs 1, 2, and 3 in the TAG pack, and the position information of the ZONE end point is stored in the absolute track numbers of PCs 1, 2, and 3 in the ZONE END pack. Stored in. Further, in the ZONE END pack, in addition to the absolute track number, playback control information of the recording / playback device in the designated ZONE is stored.

TAG pack and Z constructed in this way
The function of the reproduction control information using the ONE END pack will be described with reference to FIGS. 12 and 13.

FIG. 12 shows the TAG pack and the ZONE EN.
It is the flowchart figure which showed the outline which controls based on the case where a D pack exists, and the case where only a TAG pack exists. That is, when the tape cassette is loaded into the recording / reproducing apparatus, it is identified whether or not there is a TAG pack (ST
33).

If it is recognized that the TAG pack is present, it is then identified whether or not the ZONE END pack is present (ST34). Here, ZONE EN
If it is judged that the D pack exists, the ZONE reproduction on the tape can be controlled by the pair of the TAG pack and the ZONE END pack (ST3).
4).

If the TAG ID of the TAG pack is PR
If it is OGRAM PLAY START (0011), the program reproduction mode is entered, and TAG ID = ZON.
If it is EPLAY (0100), TAG pack and ZO
Reproduction control is performed for the ZONE designated by the absolute track number with the NE END pack according to the designated command (ST37).

If a TAG pack exists, ZONE E
If no ND pack exists, INDEX, SKI
P START, PP, STILL and FREEZE are controlled. INDEX and SKIP START,
The PP is the data stored in the TAG pack, and the same data is recorded in the subcode area provided in each track on the tape.

INDEX (TAG ID = 0000)
Is for cue playback of the tape (ST38,
ST39).

SKIP START (TAG ID = 0
001) is SKIP to the position stored in the absolute track number of the next TAG pack (ST4).
0, ST41).

PP (TAG ID = 0010) is TA
The video of the position information designated by the absolute track number of the G pack is reproduced in the still image state (ST42, ST43).

STILL (TAG ID = 0101)
14, as shown in FIG. 14, based on the position information designated by the absolute track number of the TAG pack, the still image is reproduced for a predetermined time (ST44, ST4).
5).

FREEZE (TAG ID = 0110)
As shown in FIG. 15, based on the position information designated by the absolute track number of the TAG pack, the sound is reproduced as usual and the image is reproduced as a still image for a predetermined fixed time (ST46). , ST47).

FIG. 13 shows the TAG pack and the ZONE EN.
This is for performing reproduction control based on the recording state on the tape which is recorded as a pair with the D pack, and is represented by a flow chart for the case where NO is determined in step ST35 described in FIG. is there.

There are TAG packs and ZONE END packs, and the TAG pack TAGID = 0011 (Pr
If it is not the Ogram Play Start), that is, if it is not the program reproduction, it is possible to control special reproduction, edit control, or environment control (ST).
48-ST52).

In the case of special reproduction, TAG pack and Z
The playback control of the ZONE based on the position information designated by the absolute track number of the ONE END pack is performed according to the designated command (ST48, ST49).

In the case of editing control, the pause and reproduction of a plurality of connected recording / reproducing devices are controlled. That is, it is possible to store in the memory the work for which the editor has instructed to pause, play, etc., and automatically perform this work. Therefore, the efficiency of editing work is improved (ST50, S
T51).

In the case of environmental control, for example, when a favorite recording scene is reproduced, the proof of the room is darkened or a predetermined proof is given to give a realistic sensation, or a pseudo odor is generated. It is controlled or controlled (ST52, ST53). A mini theater can be realized by using this. It is needless to say that the control is not limited to editing control, environment control, etc., and it is of course possible to use this TAG pack and ZONE END pack to add value-added information based on the recorded information on the tape. .

Next, a specific example of reproduction control between two point positions on the tape based on the information recorded on the tape shown in FIGS. 12 and 13 will be described.

(1) Tag Event = STILL The first specific example is a case of STILL reproduction as shown in FIG. 14, and the TAG ID of the TAG pack is STIL.
It is 0101 indicating L. Therefore, when you come to the position of the track number stored in this TAG pack,
The still image is played for a certain period of time, and then the normal playback is resumed. FIG. 14B is a schematic view of the contents of the memory mounted on the cassette, and the main area, the program event, and the TAG are stored in order from the smallest address. Here, the main area stores an application ID that defines the data structure of the memory, information about the recording medium, information about the recording medium cassette, and the memory. In addition, the program event stores position information of a start point and an end point of contents recorded on a recording medium (hereinafter referred to as a program), and character information regarding the program.

Further, the TAG pack stores the track number at the point A and the information TAG ID = 0101 (STILL).

(2) Tag event = FREEZE The second specific example is the case of FREEZE reproduction as shown in FIG. 15, and the TAG ID of the TAG pack is FREE.
It is 0110 indicating ZE. Therefore, when the position of the track number stored in the TAG pack is reached, the image is taken into the memory for a certain period of time, the image in the memory is continuously output to the screen, and the sound is reproduced normally. Then, the normal reproduction is resumed.

Further, FIG. 15B is a schematic view of the contents of the memory mounted on the cassette. As described above, the main area, the program event, and the TAG are stored in order from the smallest address. TAG here
The track number of the A point and TAG ID = 0 in the pack
Information of 110 (FREEZE) is stored.

(3) Tag event = DATE and TI
ME CHANGE In the third specific example, a case where TAG ID = 1000,1001 in the header (0Bh) of the TAG pack and recording is performed for several days by the camcorder will be described.

That is, on the camcorder side, the date of the last recording is stored in a storage element such as an EEPROM, and if the date of the next recording is different from the stored date, , TAG pack (header 0Bh) is recorded in the memory of the memory in cassette (MIC). At this time, the ABSOLUTE T in the TAG pack
RACK NO. The track number of the recording start point (that is, the point where the date has changed) is recorded in the field, and DATE CHANGE (1000) is recorded in the TAG ID.

For example, a case of recording on a camcorder for three days will be described with reference to FIG. 22 and according to the flowchart of FIG. First, when the recording of SCENE1 is completed, the date when the SCENE1 was recorded (for example, July 6) is stored in the camcorder. next,
When recording SCENE2, the current date (for example, 7
The stored date (July 6th) is compared with the stored date (July 6th) (ST54).

In this case, since the two are different, the track information, that is, the track number (eg TRACK
NO. = 362915), TAG ID = 1000 (D
The TAG pack as ATE CHANGE) is recorded in the memory of the tape cassette (ST55). SCENE2
When the recording of is completed, the date when recording SCENE2 (July 7) is stored in the camcorder (ST56 → ST5).
7).

Next, at the time of recording SCENE3, the dates are similarly compared, and since both are the same, the TAG pack is not recorded in this case (ST54). SCENE3
At the end of the recording, the date when recording SCENE 3 (July 7
Date is stored in the camcorder (ST56 → ST5)
7).

When recording the SCENE 4 again, the dates are compared in the same manner as in the previous example. In this case, since the two are different, track information, that is, track number (for example, TRACK NO. = 632401), TAG ID
= 1000 (DATE CHANGE) is recorded in the memory of the tape cassette (ST54 →
ST55). At the end of the SCENE4 recording, S
The date when CENE4 was recorded (July 10) is stored in the camcorder (ST56 → ST57).

Next, the case of reproducing a tape in which the information of the change of the date and time at the time of recording on the tape is not recorded in the MIC will be described with reference to the flowchart of FIG.

When the tape is reproduced, that is, reproduced or searched, and a point at which the date and time changes is found, track information at that point, that is, track number and ID information (DATE CHANGE, TIME CHANGE).
Are generated in the MIC using the TAG pack (ST
58 → ST59). Therefore, even if the date / time transition is not stored during recording, if the date / time transition is detected during playback, the track information at that time can be stored.

Time transition (TAG ID = 100
Regarding 1), by setting the time in advance, it becomes possible to search for an image every 10 minutes, for example, or to search for an image without a commercial part.

In this way, since the track information at the transition of the date and time is recorded in the memory in the MIC,
By comparing the track number of the point where the head is currently located with the track number of the search target point, it is possible to determine how fast the search should be performed, and the search target point can be reached with optimal control. Of.

(4) Zone event = SKIP reproduction A fourth specific example is a case of SKIP reproduction, as shown in FIG. Is the track No. at point A. And the TAG ID is the Zone Play (L of PC4, which indicates the ZONE starting point).
SB1-4 bits = 0100).

Then, the track No. of the ZONE END pack is set. Is the track No. at point B. And also TAG
In CONT (PC4), the upper 2 bits = 01 (Pla
y; Play once) and SKIP by fast forward (FF)
If so, FMODE = 100 (FF), and the queue (C
If SKIP by UE), FMODE = 011 (Cu
e), and at this time, RMODE = 000 (No Ope
relation). Therefore, SKIP is performed from the position of the absolute track number designated by the TAG pack (point A in FIG. 25A) to the position of the absolute track number designated by the ZONE END pack (point B in FIG. 25A). For example, it is effective for deleting unnecessary screens such as commercials.

(5) Zone event = 1 repetitive reproduction The fifth specific example is as shown in FIG.
Playback is repeated only once in E. TA
Track No. of G pack Is the track No. at point A. And T
AG ID is Zon indicating that it is the ZONE starting point
e Play (LSB of PC4 1 to 4 bits = 010
0). The track number of the ZONE END pack is Is the track No. at point B. At TAG CONT
In (PC4), the upper 2 bits = 10 (Play 2
Times; repeated reproduction once) and repeated twice for reproduction, so FMODE = 001 (Play),
RMODE = 100 (Rewind).

Therefore, from the position of the absolute track number designated by the TAG pack (point A in FIG. 26A), ZONE
After the reproduction to the position of the absolute track number designated by the END pack (point B in FIG. 26A), REWIND to the position of point A again, it is possible to reproduce again.

(6) Zone event = reverse rotation reproduction In the sixth concrete example, as shown in FIG.
Reverse playback is performed in E, and TA of the TAG pack
G ID is the Zone that indicates the ZONE starting point
Play (LSB 1 to 4 bits of PC4 = 0100)
Is. And the TAG C of the ZONE END pack
In the ONT (PC4), the upper 2 bits = 10 (Play
2 times; repeated playback once), and FMO
DE = 100 (FF), RMODE = 001 (Reve
rse Play).

Therefore, from the position of the absolute track number designated by the TAG pack (point A in FIG. 27A), ZONE is set.
After fast-forwarding (FF) to the position of the absolute track number specified by the END pack (point B in FIG. 27A),
Reverse playback to point A (REVERSE PLAY)
And then fast-forward (FF) again to the position of point B.

(7) Zone Event = Program Playback 1 In the seventh specific example, as shown in FIG. 28, program playback is performed from the position designated by the TAG pack. → Program 2
-> When program 3 is recorded in order, the reproduction is performed in the order of program 2-> program 1-> program 3. In this case, one TAG
It is formed of a pack and five first to fifth ZONE END packs. Track No. of one TAG pack. Is the track No. at point B. The TAG ID indicates that it is the starting point of the program. Program Play St
art (LSB 1 to 4 bits of PC4 = 0011).

Then, the track No. of the first ZONE END pack is set. Is the track No. at point C. At TAG CO
In the NT (PC4), the upper 2 bits = 01 (Play;
(Play once), FMODE = 001 (Play),
RMODE = 000 (NoOperation).

The track No. of the second ZONE END pack. Is the track No. at point A. TAG CONT (P
In C4), the upper 2 bits = 01 (Play; played once), and FMODE = 000 (No Operat)
ion) and RMODE = 100 (Rewind).

Track No. 3 of the third ZONE END pack. Is the track No. at point B. TAG CONT (P
In C4), the upper 2 bits = 01 (Play; once reproduced), FMODE = 001 (Play), RMO
DE = 000 (No Operation).

Track No. 4 of the fourth ZONE END pack. Is the track No. at point C. TAG CONT (P
In C4), the upper 2 bits = 01 (Play; reproduced once), FMODE = 100 (FF), RMODE
= 000 (No Operation).

The track No. of the fifth ZONE END pack. Is the track No. at point D. TAG CONT (P
In C4), the upper 2 bits = 01 (Play; once reproduced), FMODE = 001 (Play), RMO
DE = 000 (No Operation).

Therefore, from the position of the absolute track number designated by the TAG pack (point B in FIG. 28A), ZONE is set.
After PLAYing up to the position of the absolute track number designated by the END pack (point C in FIG. 28A), REWIND from the position of point C to the position of point A, and again the position of point A to position B Until the position of point C to the position of point C, and FULL FORWARD from the position of point C to the position of point D. In this way, even if the program 1 → program 2 → program 3 is recorded in order on the tape, it can be reproduced as if it was edited like program 2 → program 1 → program 3.

The ZONE END pack and the next Z
With respect to the ONE END pack, the ZONE end point (A point, B point, C point, D point) may be specified by each absolute track number, and the relationship with the TAG pack is the first ZON.
Since only the E END pack is used, the limited memory area can be effectively used.

(8) Zone event = program reproduction 2 In the eighth specific example, as shown in FIG. 29, the reproduction of the program from the position designated by the TAG pack is changed, and, for example, on the tape. To program 1 →
When the program 2 → program 3 → program 4 is recorded in order, the reproduction is performed by the program 1 (PL
AY)-> Program 2 (SLOW)-> Program 3 (F
F) → Program 4 (PLAY) is changed and reproduced.

In this case, one TAG pack and four first to fourth ZONE END packs are formed. Track No. of one TAG pack. Is the track No. at point A. The TAG ID indicates that it is the program start point. Program Play Start (P
LSB 1 to 4 bits of C4 = 0011).

Then, the track No. of the first ZONE END pack is set. Is the track No. at point B. At TAG CO
In the NT (PC4), the upper 2 bits = 01 (Play;
(Play once), FMODE = 001 (Play),
RMODE = 000 (NoOperation).

The track No. of the second ZONE END pack. Is the track No. at point C. TAG CONT (P
In C4), the upper 2 bits = 01 (Play; once reproduced), FMODE = 010 (Slow), RMO
DE = 000 (No Operation).

The track No. of the third ZONE END pack. Is the track No. at point D. TAG CONT (P
In C4), the upper 2 bits = 01 (Play; reproduced once), FMODE = 100 (FF), RMODE
= 000 (No Operation).

Track No. 4 of the fourth ZONE END pack. Is the track No. at point E. TAG CONT (P
In C4), the upper 2 bits = 01 (Play; once reproduced), FMODE = 001 (PLAY), RMO
DE = 000 (No Operation).

Therefore, from the position of the absolute track number designated by the TAG pack (point A in FIG. 29A), ZONE is set.
After playing to the position of the absolute track number designated by the END pack (point B in FIG. 29A), playback by SLOW is performed from the position of point B to the position of point C, and from the position of point C to point D again. To the position of FORWAR
Perform RD and play from the position of point D to the position of point E. Thus, even if the programs are recorded in this order on the tape in the order of program 1 → program 2 → program 3 → program 4, program 1 is a normal PLAY playback, program 2 is a SLOW playback, and program 3 is FULL.
FORWARD, program 4 again normal PLA
It is possible to reproduce Y and reproduce it as if it were edited.

As in the seventh embodiment, ZONE E
Between the ZONE END pack that follows the ND pack and the ZONE end point (B
(Point, C point, D point, E point) need only be specified. Since the relationship with the TAG pack is only the first ZONEEND pack, the limited memory area can be effectively used.

(9) Zone Event = Program Reproduction 3 As shown in FIG. 30, in the ninth concrete example, the reproduction of the program from the position designated by the TAG pack is changed as in the seventh concrete example. Is performed by, for example,
When the program 1 → program 2 → program 3 is recorded in order on the tape, the playback is changed to program 1 (PLAY) → program 2 (play twice) → program 3 (PLAY). Is to do.

In this case, one TAG pack and three first to third ZONE END packs are formed. Track No. of one TAG pack. Is the track No. at point A. The TAG ID indicates that it is the program start point. Program Play Start (P
LSB 1 to 4 bits of C4 = 0011).

The track No. of the first ZONE END pack is set. Is the track No. at point B. At TAG CO
In the NT (PC4), the upper 2 bits = 01 (Play;
(Play once), FMODE = 001 (Play),
RMODE = 000 (NoOperation).

Track No. 2 of the second ZONE END pack. Is the track No. at point C. TAG CONT (P
In C4), the upper 2 bits = 10 (Play 2 Ti)
mes; replayed twice) and FMODE = 010 (Sl
ow) and RMODE = 100 (Rewind).

The track No. of the third ZONE END pack. Is the track No. at point D. TAG CONT (P
In C4), the upper 2 bits = 01 (Play; once reproduced), FMODE = 001 (Play), RMO
DE = 000 (No Operation).

Therefore, from the position of the absolute track number designated by the TAG pack (point A in FIG. 30A), ZONE
After the playback at the normal speed PLAY is performed up to the position of the absolute track number designated by the END pack (point B in FIG. 30 (A)), SL is performed from the position of point B to the position of point C.
Playback by OW, REWIND from the position of C point to B position again, play by SLOW again from the position of B point to C position, and from the position of C point to the position of D point at normal speed Playback can be performed.

As described above, even if the programs are recorded on the tape in the order of program 1 → program 2 → program 3, program 1 is a normal PLAY reproduction, and program 2 is a SLOW / REWIND reproduction of SLOW.
The program 3 can be played back at regular speeds and played back as if it were edited.

In addition, as in the eighth embodiment, ZONE E
One ZONE specified by each absolute track number between the ZONE END pack that follows the ND pack.
(B point, C point, D point) need only be specified, and since the relationship with the TAG pack is only the first ZONEEND pack, the limited memory area can be effectively used.

(10) Zone event = character output In the tenth specific example, as shown in FIG.
Characters such as titles are output on the screen during reproduction in the NE, and the track number of the TAG pack. Is the track No. at point A. TAG ID is ZONE PLAY indicating that it is Zone Play (LSB of PC4
~ 4 bits = 0100). And ZONE E
Top 4 in TAG CONT (PC4) of ND pack
Bit = 0000 (Control of Chara
(Racter Output Term).

Therefore, from the position of the absolute track number designated by the TAG pack (point A in FIG. 31A), ZONE
Characters stored in the TEXT pack can be output on the screen up to the position of the absolute track number designated by the END pack (point B in FIG. 31A). Therefore, it is possible to obtain a composite image as if characters and the like were fitted on the recording screen without any editing of the data recorded on the tape.

Until now, TAG packs and ZONE EN
I showed various special playback methods using D packs,
In addition, by using the TAG pack and the ZONE END pack, it is possible to apply, for example, to prohibit recording of the ZONE, or to determine whether to view an image recorded after timer recording. These examples will be described below.

(11) Zone Event = Prohibition of Recording In the eleventh specific example, as shown in FIG.
Recording is prohibited in the NE so that the NE cannot be overwritten. Is the track No. at point A. The TAG ID is Zone Play indicating that it is ZONE PLAY (LSB1 to PC1 of the PC4.
4 bits = 0100). And ZONE EN
Track No. of D pack Is the track No. at point B. And T
Upper 4 bits = 000 in AG CONT (PC4)
1 (Rec Proof).

Therefore, from the position of the absolute track number designated by the TAG pack (point A in FIG. 32A), ZONE is set.
In the ZONE up to the position of the absolute track number designated by the END pack (point B in FIG. 32A), it is possible to protect the recording recorded by setting the recording prohibited state so that overwrite cannot be performed.

(12) Zone event = reproduced In the twelfth specific example, as shown in FIG. 33, it is indicated that reproduction is performed once or more after recording such as timer recording. Track No. of the TAG pack. Is A
Dot Track No. TAG ID is ZONE PL
Zone Play that indicates AY (L of PC4
SB1-4 bits = 0100), and ZONE EN
Track No. of D pack Is the track No. at point B. And T
Upper 4 bits = 001 in AG CONT (PC4)
0 (Already Played).

Therefore, from the position of the absolute track number designated by the TAG pack (point A in FIG. 33A), ZONE is set.
In the ZONE up to the position of the absolute track number designated by the END pack (point B in FIG. 33A), it is possible to easily discriminate that one or more reproductions have been performed after the recording. . Then, when a new recording such as overwriting is performed in the designated ZONE, it is not already reproduced.

[9] Device Next, the recording / reproducing device described with reference to FIG. 1, that is, the recording side circuit and the reproducing side circuit of the VTR will be described with reference to FIG.
This will be described below with reference to FIGS. 35 and 36.

(1) Recording Side Circuit In the recording side circuit, as shown in FIG. 34, the TV radio signal input from the antenna 1 is received by the tuner unit 2 and restored to a composite video signal and audio signal. To be done.

This composite video signal is selected by the signal from the external analog video input 4 and the switch 3a and added to the Y / C separation circuit 6. This circuit separates the luminance signal (Y) and the color difference signals (RY, BY).

On the other hand, the signal from the switch 3a is also given to the sync separation circuit 11. Where V sync signal and H
Separate the sync signal.

Both of these 12 PLLs (Pha
se locked loop) circuit is used as a reference signal, where 13.5 MHz, which is the original basic sampling frequency locked to the input signal, is generated. This frequency is called a rate of 4, but since this amount of information is not usually required for a color signal,
This frequency is used to make a half or a quarter of this frequency, and sampling is performed with this frequency.

In the present embodiment, 525 lines / 60 Hz NT
The SC performs sampling at a rate of 4: 1: 1, and the PLL of 625 lines / 50 Hz is 4: 2: 0.

Before converting the analog output of the Y / C separation circuit 6 into a digital signal, LPFs (Low Pass) 7a, 7b, and 7c are formed in order to remove aliasing distortion.
Filter) to limit the bandwidth.

The cutoff frequency of the filter is selected to be, for example, 5.75 MHz for Y, 2.75 MHz for RY and BY for 2.75 MHz, and 1.45 MHz for 1 rate. The signals preprocessed in this way are converted into 8a, 8
It is converted into a digital signal by the A / D converters b and 8c.

The digital signal thus obtained is subjected to DCT
(Descrete Cosine Transform)
In order to perform block compression encoding using m), data on the real screen is processed into blocks of 8 samples × 8 lines by a blocking circuit of 9.

Thereafter, the shuffling circuit of 10 effectively disperses the data. This is a measure for avoiding intensive loss of data recorded on the tape due to head clogs or lateral scratches on the tape. At the same time, in 10, the luminance signal and the color difference signal are rearranged so that they can be easily processed in the subsequent stage.

The data compression encoding unit 14 includes a DCT compression circuit, an estimator for estimating whether the result can be compressed up to a predetermined data amount, and a quantizer for final quantization based on the result of the judgment. Consists of. The video data compressed in this way is packed in a predetermined SYNC block by a framing circuit of 15.

The pack data of VAUX, AAUX, and Subcode and the track number name stored in Subcode are generated by the signal processing microcomputer 20.
The result is given to the interface ICs 17, 18 and 19 which provide the connection between the microcomputer and the hardware.

The IC 17, which is in charge of VAUX, also generates AP2, and synthesizes it with the framing output by the synthesizer 16 in timing. Similarly, the IC 18 in charge of the subcode generates the data SID of the ID part, AP3, and the pack data SDATA of the subcode.

On the other hand, the audio signal is selected as an output from the tuner section 2 or a signal from the external analog audio input 5 by the switch 3b, and then converted into a digital signal by the A / D converter 21 and shuffled by 22. The data digitized by the circuit is effectively separated, and is packed in the audio SYNC block by the framing circuit 23.

[0200] The IC in charge of AAUX 19 combines the packs of AP1 and AAUX with the combiner 24 at the same timing.

In 25, AV (AUDIO / VIDE)
O) each ID and PRE-SYNC, POST-SYNC
Is generated and these data are switched by the switch 26.

Predetermined parity is added by the error correction code generation circuit 27 at the next stage, and it is sent to the next channel decoder.

In 29, randomization is performed so that the recorded data is not biased, and the 24/25 conversion circuit 30 performs coding to remove the DC component.

Here, a PR suitable for digital recording is further used.
IV (partial response, class 4) coding processing 1 / 1-D × D) is also performed.

The signal thus obtained is added to AUDIO / V
SYNC pattern of IDEO, SYNC of SUBCODE
The C pattern is synthesized by the synthesizer 31.

Reference numeral 33 is an ITI sector generation IC.
Data of each of APT, SP / LP, and PF is given here from a mode processing microcomputer 34 which manages the mode of the entire VTR, and the data is fitted into a predetermined position and added to the switch 32.

The switch 32 switches between these data and the amble pattern by observing the timing.

The mode processing microcomputer 34 sets the recording mode of SP / LP, and the result is given to each microcomputer via the communication network. The final recording signal thus obtained is switched by the switch 35 at each head switching timing.

The signals amplified by the head amplifiers 36a and 36b are applied to the heads 37a and 37b, and the signals are recorded on the tape.

38 is MIC (Memory In Ca)
A microcomputer for processing. Where MI
Generates pack data and APM etc. in C, and MIC contact 3
It is given to the in-cassette memory of 40 through 9. The above-mentioned series of operations is performed by a linked play of the mechanical control microcomputer 28, the mechanical control microcomputer 28, the signal processing microcomputer 20 and the ICs of each part.

(2) Reproducing Side Circuit Next, the reproducing side circuit of the recording / reproducing apparatus will be described with reference to FIGS. As shown in FIGS. 35 and 36, in the reproducing circuit, the weak signals input from the heads 41a and 41b are amplified by the head amplifiers 42a and 42b, and are switched by the switch 43 with timing. It is added to the equalizer (EQ) circuit 44.

The equalizer circuit 44 is so-called emphasis processing (for example, partial response c) in order to improve the electromagnetic conversion characteristics of the tape and the magnetic head during recording.
However, the reverse processing is performed.

A clock extraction PLL circuit 45 extracts a clock component from the output of the equalizer circuit 44. Using this, the output of the equalizer circuit 44 becomes A
It is digitized using the / D converter. The 1-bit data thus obtained is extracted into the FIFO 47 as a clock CK.
Write using.

The clock CK is a temporally fluffy and unstable signal containing a jitter component of the rotary head drum. However, since the data itself before A / D conversion is fluffy, there is no problem in sampling itself.

However, when the image data and the like are to be extracted, the data cannot be extracted unless the data is stable and stable in time, so the time axis adjustment is performed using the FIFO 47. That is, writing is performed with an unstable clock, but reading is performed with a stable clock SCK through a frequency divider 80 from a signal from an oscillation circuit 79 such as a crystal oscillator 78.

The depth of the FIFO 47 is set to have a margin such that the data is not read faster than the input speed of the input data.

The output of each stage of the FIFO 47 is 48 S
It is added to the YNC pattern detection circuit. Here, the SYNC pattern of each area is switched by the switch 49 by the timing circuit 53 and given.

The SYNC pattern detection circuit 48 has a so-called flywheel structure, and once a SYNC pattern is detected, it is checked whether or not the same SYNC pattern comes again after a predetermined SYNC block length.
For example, if it is correct three times or more, it is regarded as true to prevent erroneous detection. The depth of the FIFO 47 is
This few minutes is necessary.

When the SYNC pattern is detected in this manner, the shift amount is determined which part of the output of each stage of the FIFO 47 should be extracted to extract one SYNC block. The bit is taken into the SYNC block confirmation latch which is 51. As a result, the fetched SYNC number is fetched by the SYNC number extraction circuit 52 and input to the timing circuit 53. Since the position on the track where the head is located can be known from the read SYNC number, the switches 49 and 54 are switched accordingly.

The switch 54 is switched to the lower side at the time of the ITI sector, and the ITISYNC pattern is removed by 55 and added to the ITI decoder 56.
Since the ITI area is coded and recorded,
By decoding it, APT, SP / LP,
Each data of PF can be taken out. This is supplied to a mode processing microcomputer 57 which is connected to an operation key 58 outside the set and which determines an operation mode and the like of the entire set.

The mode processing microcomputer 57 is connected with the MIC microcomputer 59 for managing the APM and the like. MIC
Information from the attached cassette 61 is the MIC contact switch 6
It is given to the MIC microcomputer 59 via 0, and performs the processing of the MIC while sharing the role with the mode processing microcomputer 57. Depending on the set, the MIC microcomputer 59 may be omitted and the mode processing microcomputer 57 may perform MIC processing.

The mode processing microcomputer 57 cooperates with the mechanical control microcomputer 68 and the signal processing microcomputer 91 to perform system control of the entire set.

In the case of the A / V sector and the Subcode sector, the switch 54 is switched to the upper side. 6
After extracting the SYNC pattern of each sector by 2, the data is returned to the original data string in addition to the inverse randomization circuit 64 by the 24/25 inverse conversion circuit 63. The data thus taken out is added to the error correction circuit 65.

The error correction circuit 65 uses various strategies to detect and correct error data.
Data that could not be retrieved by any means is output with an ERROR flag. Each data is switched by the switch 66. The circuit 67 is in charge of the ID part of the A / V sector and each SYNC of Pre and Post, and here, the SYNC number, the track number and the Pre-SYNC.
Each of the SP / LP signals stored in is extracted. These produce various timings given to the timing circuit 53.

Regarding the SP / LP, the mode processing microcomputer 57 carries out a comparative examination with that obtained from ITI. In the ITI area, S 3 times in the TIA area.
The P / LP information is written, and only there is taken a majority vote to improve reliability.

In Pre-SYNC, there are 2 SYNCs for audio and 2 SYNC for video, respectively, and SP / LP information is written at four locations in total. Here too, there is a majority vote to improve reliability. Finally, if they do not match, the ITI area is preferentially adopted.

VDATA is set to Vid by the switch 69.
It is divided into eo data and VAUX data. Vid
The eo data is given to the deframing circuit 70 together with the ERROR flag. The deframing circuit 70 performs the inverse conversion of the framing, and grasps the property of the data packed therein. Therefore, when there is an error that can not be caught in one data, I understand how it affects other data, so I will handle the propagation error here. As a result, the ERROR flag becomes a VERROR flag that newly includes a propagation error. Of course, if the error data is not important for image reproduction,
The deframing circuit also performs processing for making a certain modification to the image data and deleting the error flag.

The image data is added to the data decompression coding section. That is, the data before compression is restored through the inverse quantization circuit 71 and the inverse compression circuit 72. Next, the data is returned to the original image space arrangement by the deshuffling 73 and the deblocking 74. Only after returning the data to the real image space, the image concealment becomes possible based on the VERROR flag. That is, for example, the image data of one frame before is always stored in the memory, and the image block in error is substituted with the previous image data. This uses the correlation with the previous image, and of course, when there is no correlation like a scene change, the deception does not work. However, this method is often used as a last resort.

Now, after the deshuffling 73, the data is divided into three systems of the luminance signal and the color difference signal and handled. And 7
5a, 75b, 75c D / A converters for Y, R-
The analog components of Y and BY are returned. As the clock at this time, an oscillation circuit 79 and an output obtained by dividing the oscillation circuit by a frequency divider 80 are used. That is, Y is 13.5 MHz, R-
Y and BY are 6.75MHz or 3.375MHz
Is. The three signal components thus obtained are combined by the Y / C combination circuit 76, and by the composite synchronization signal 77 of the synchronization signal generation circuit 81, and output from 82 as a composite video signal.

ADATA is added to Aud by the switch 83.
It is divided into io data and AAUX data. Aud
The io data is given to the deframing circuit 84 together with the ERROR flag. The deframing circuit 84 performs the inverse conversion of the framing and grasps the property of the data packed therein. Therefore, when there is an error that can not be caught in one data, I understand how it affects other data, so I will handle the propagation error here. For example, at the time of 16-bit sampling, since one data is in 8-bit units, one ERR
The OR flag will span two data. As a result, the ERROR flag becomes an AERROR flag that newly includes a propagation error.

The audio data is returned to the original time axis by the next deshuffling circuit 85. At this time, the audio data repair work is performed based on the AERROR flag. That is, since an error in the audio immediately becomes a "buzzing" sound, processing such as holding the previous value is performed in which the sound immediately before the error is substituted. If the error period is too long and the deception does not work, processing such as muting is performed to stop the sound itself. After such processing, the analog value is returned to the analog value by the D / A converter 86, and the image data is output to 87 while timing of lip sync and the like is taken.

The respective data of VAUX and AAUX separated by the switches 69 and 83 are subjected to preprocessing such as majority processing with reference to error flags by dedicated ICs 88 and 90. Subcode sector ID
The section SID and the data section SDATA are given to the dedicated IC 89, and here also preprocessing such as majority processing is performed with reference to the error flag. Then, it is given to the signal processing microcomputer 51, and a final reading operation is performed. The errors that could not be removed at this time were VAUXER and
Signal processing microcomputer 91 as SUBER and AAUXER
Given to. Each of the ICs 88, 89, 90 also performs a process of generating AP2, AP3, AP1.

If the error handling here is supplemented,
Each area has a main area and an optional area. And in the case of 525 / 60Hz system,
The same data is written 10 times in the main area. Therefore, even if some of them have an error, they can be supplemented and reproduced with other data, and the ERROR flag there is no longer an error. However, since the data is written once in the optional areas other than Subcode, the error remains VAUXER, SUBER, AA.
It will remain as a UXER.

The signal processing microcomputer 91 further performs propagation error processing, data repair processing, and the like by analogy with the context of the pack of each data. The result of this judgment is
It is given to the mode processing microcomputer 57 and used as a material for determining the behavior of the entire set.
