Abstract

A method for storing an A / V information signal sequence, such as video / audio information, and corresponding control information signals, such as video control, menu information, or file information, on sequentially recordable disc-shaped media, such as a single-write and readable disc. The recorded information corresponds to the requirements of a read-only or rewritable disk for the sorting of such information. During this procedure, a reserved area is assigned within a linear addressing area, sequentially captured in a video recording area adjacent to the area occupied by the A / V information signals, and corresponding control data is recorded in a temporary overview area adjacent to the avide-recording area, to create a single mapping table for mapping the recorded control data to the occupied location addresses of the recorded control data and fix the mapping table in the temporary review area. Upon finalization of the disk, the fixed control information signals are copied according to the information of the last mapping table of the occupied area beam, and the data of the remaining unoccupied portions of the occupied area are recorded.

A method and apparatus for recording a digital information signal

Field of the Invention The present invention relates to a method of organizing an A / V information signal sequence, such as video / audio information, and an appropriate control information signal, such as video control, menu information, or file information, to a recordable write-once disc such as an optically writable and readable disc. the recorded information corresponds to the requirements of a read-only or rewritable disc for the sorting of such information.

The present invention also relates to an apparatus for sequentially storing a sequential A / V information sequence, such as video / audio information, and a corresponding control information signal such as video control, menu information, or file information, the recorded information corresponds to a read-only or rewritable disk. requirements for arranging such information, the recording apparatus comprises means for rotating a disc-sized write-once recordable medium such as an optically writable and readable disc, a device suitable for modifying the laser beam according to digital information signals to be recorded on the disk-shaped media, means , which is suitable for detecting the reflection of the laser beam on the disc-shaped media and transforming the reflection into the digital information to be read »

• · •,, a device suitable for modulating the received digital A / V information signals to be recorded as information signals, and a means for controlling the recording and reading of the digital information signal.

A similar method and apparatus is known, for example, from WO 01/01416A1 (PHN 17522), but the method and apparatus disclosed therein apply only to rewritable discs.

The video recording format (DVD-Video Format) described in the above-mentioned document was originally designed to store audio-visual content on a read-only disk, such as a duplicate disc (DVDROM / Video). The referenced application also describes a version of the DVD-Video format, DVD + RW

Video format suitable for playback-compatible video storage on real-time rewritable discs (DVD + RW).

However, for financial reasons and for the purpose, users prefer pre-writable media to rewritable media. The DVD + RW Video format can be used, but it has the disadvantage that certain control information and menu structures must be recorded before the actual video content. Without the control information, the disc is not compatible with DVDROM / Video or DVD + RW players.

On a write-once disc, such information can be stored only once so that no more recording or recording changes can be made without risk of compatibility.

It is an object of the present invention to overcome the aforementioned disadvantage. According to our object, the present invention is a process,

where an area is allocated within a linear addressing area, the A / V information signals are recorded in a video recording area in the area following the seized area, the corresponding control data is recorded in the temporary review area following the video capture area, a mapping table is created by the fixed controller to map data to address the locations in the reserved area, and record the mapping table in the temporary review area.

In another aspect, the present invention relates to a recording device, wherein the control means is suitable for allocating an area within a linear addressing area on a disc-shaped media, for recording A / V information signals in a video recording area following a reserved area, and corresponding control data in a temporary review area following the video recording area. to capture a mapping table for mapping the recorded control data to address locations in the reserved area and to capture the mapping table in the temporary review area.

The invention is based on the idea of mapping a virtual control area to a real physical location with a mapping table. The control data structure should only be copied to the appropriate location of the seized area when the disk is finalized, ie when creating an introductory and output area for playing a compatible disc.

In a preferred embodiment of the method according to the invention, a subsequent A / V information sequence is recorded in the next video recording area following the previously recorded areas, and the next appropriate control data is recorded in the next overview area following the next video capture area, a mapping table is created for mapping the first and next fixed control data to address the allocated area locations and recording the mapping table in the next temporary review area.

This has the advantage of recording multiple A / V information sequences on the disk.

In another preferred embodiment of the method according to the invention, appropriate control information signals are generated, at least the updated control information signals are recorded in the next temporary overview area following the previous temporary review area, an updated mapping table is created to map the updated control data and the remaining control data area mapping and record the updated mapping table in the next temporary review area.

Thus, it is possible to update the control data when editing a fixed A / V stream.

In a further preferred embodiment of the method according to the invention, the recorded control information signals are copied to the reserved area in accordance with the latest mapping table information, the remaining unrecorded portions of the seized area are recorded with arbitrary data signals, an introductory area is recorded which is read-only or readable contains data corresponding to the definition of a rewritable disc, after recording the recorded area, recording an output area with data that is readable only for read-only or rewritable disc, or with closing data closing the current video recording section.

This makes it easy to record control data to ensure playback compatibility.

Examples of a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

I

Figure 10 shows a recording method according to an embodiment of the invention using the reserved area allocation table.

Figure 11 is a schematic view of a fastening device according to the invention.

Figure 1 shows a video data structure of a read-only optical DVD 1. The data series is arranged from left to right according to increasing logic sector numbers (LSN), where a sector is the smallest unit of addressing data stored on the DVD. A sector typically corresponds to 2048 user data bytes. For the sake of simplicity, other disk areas, such as the introductory area and the outlet area, are not shown.

The Video Data Structure 1 contains 2 Volume and Fiié System (VOL / FS) data, 3 Video Controls (Video Manager = VMG) data, and more 4 Video Title Sets (Video

Title Set = VTS # 1, VTS # 2, VTS # 3, VTS # n).

The volume and file system 2 defines the DVD video volume area according to the universal disk format (UDF). In one volume, the video data consists of 3 video controls (VMG) and one or more 4 Video Title Sets (VTS). File system data allows addressing data objects in so-called DVD video zones containing 3 video control data (VMG) and 4 video address sets (VTS). Adapting data objects to this video zone may require adapting the file system data.

A 4 video title set (VTS # n) is the unit that describes a full video content or title. This consists of: 5

VTS Information (VTSI # n) in the 4 Video Address Kit (VTS # n) for Address and Menu Control, 6 Video Objects Set for Menu (VTSM_VOBS), 7 Video Objects Set for Address (VTSTT_VOBS) and 8 Backups for VTSI (BUP_VTSI). A Video Object Set (VOBS) is a set of video objects (VOBs). A VOB is an MPEG program stream consisting of a group of elemental streams, such as video, audio, subpicture, program control information (PCI), and data retrieval information (DSI).

The layout of VTSI 5, VTSM_VOBS, VTSTT_VOBS, and VTSI_BUP 8 must be performed in this order. The files containing the 7 VTSTT_VOBSt must be distributed sequentially.

The 3 video controls include 9 video control information (VMGI), the 10 video object set for the VMG menu (VMGM_VOBS) and the 11 VMGI backup (VMGI_BUP).

In Figure 2, 12 DVD-video data structures are shown on a rewritable DVD according to the DVD-RW type, in the figure the same reference numbers are used for the same parts as in Figure 1. The DVD video data structure 12 is according to the method and recording device described in WO 01/01416-A1 (PHN 17522). Existing for read-only DVD discs

In order to maintain compatibility with DVD players, account should be taken of the constraints of the appropriate video data structure 1 on these discs, especially when recording more.

In our example shown in Figure 2, there are three recordings (TITLE / TITLE) recorded by the 7 video object set for the address (VTSTTT_VOBS # 1, VTSTT_V0BS # 2, VTSTT_V0BS # 3) and the corresponding 5 video address set information (VTSI # 1, VTSI # 2, VTSI # 3). The feature of the referenced process is the order of these data, where the VTSI VTS control information 5 always precedes the VTSTT_VOBS video object set, and the VTSI_BUP backup data 8 always follows. This series of data can be considered as a video object address set (VTSTT_VOBS) which corresponds to the constraints of a DVD-video data structure of read-only DVD-video disc 1.

In addition to these data, you can also find the 13 video recording control information data (VRMI) and the corresponding 14 VRMI_BUP backup. It contains information that identifies the type of recorder that generated the DVD / video menus on the disc. No other characteristic recording information is shown in the figure, such as the Video Recording Control Workspace (VRM Scratch), which recorders can use for temporary data storage, and the VRM user data area that can be used to add other operational functions of some recorders. This data will be adjacent to the 13 VRMI data.

Figure 3A illustrates an example of a DVD video data structure 15 for a write-once DVD after a first recording according to a first embodiment of the invention. The first recording is represented by the appropriate file and control information stored in the VTSTT_VOBS # 1 and 16 control data areas (MGT1-1, MGT1-2, MGT1-3).

These areas include VTSI # 1, VMG, VRMI, and file system information such as UDF. In addition, the VTSI backup file, VRMI and a second ADVP are fixed sequentially in this order.

ADVP stands for the Anchor Volume Descriptor Pointer required by the UDF file system. The ADVP is always stored in a fixed location so that a computer system can recognize that the data is stored in UDF format. ADVP specifies the location of a logical volume descriptor series (LVDS) that contains a data structure sequence for the structure and location of the data stored on the disk.

This includes references to one or more file set descriptors (FSDs). Thus, ADVP can be considered as the beginning of the file system (UDF). The second ADVP is a backup of this first ADVP.

By explaining the invention, it is not necessary to indicate the type of control data, only the occupied areas. The temporary review area 17 includes all the control information and file information required by the DVD / video data structure for the rewritable DVD described in the aforementioned patent application.

However, the control data areas 16 (MGTs) are not fixed in front of the VTSTT_VOBS 7, as would normally be required for a read-only or rewritable DVD Video Data Structure of the DVD disc, but for VTSTT_VOBS of the first recording in the TOS 17. after. This temporary review area 17 (TOS) includes a reserved area allocation table (RSAT) 18, which includes mapping the control data areas to the locations in the occupied area 19 before the VTSTT_VOBS. The reserved area 19 is not used for recording until the last recording is completed until the disc is finalized. In the finalization step, all 16 control data areas are copied to this occupied area 19 using the mapping in the occupied area allocation table 18. Only with this finalization step can we ensure the compatibility of playback of read-only or rewritable DVD video discs with DVD players. This will be explained in detail later.

The occupied area 19 begins after the introductory area 20 and ends at the logic sector number R. For a typical DVD disc, the first physical sector after the 20 introductory areas is 0003

From OOOOh (h: hexadecimal) to the start of the outlet area (LO) 21, for example, 00026 to 0540h. This corresponds to a total of 2 295 104 (d: decimal) physical sectors, with a physical sector

Contains 2048 user data bytes.

However, for the purpose of addressing, all physical sectors are trained in logical sectors with a logical sector numbering (LSN). After the end of the introductory area 20, the start of the recording area is indicated by the logical sector number 0000-0000h and until the start of the outlet area 21, logic sector 0022 FF40h.

The occupied area 19 is arranged from the 0000 OOOOh logic sector number (or 0003 OOOOh physical sector number) to the 0000 3FFF h logic sector number (or 0003 3FEFh physical sector number) according to about 32 Mbytes. This value is selected for the rewritable DVD disc DVD video data structure. But the occupied area 19 can be any size. In addition, there may be more occupied areas.

• · • ·

The mapping can be applied based on error correction blocks (ECC blocks). A typical DVD ECC block may contain, in addition to error correction data, sixteen physical sectors. Within an ECC block, the data is recorded at the current location in the same order as it would have been outside the planned location.

Further fixings must be made after the 17 temporary review areas in the unrecorded area (UNREC). As long as it can be written

A DVD is not finalized, which is also indicated by the presence of an open section, and the reserved area 19 cannot be recorded.

Figure 3B illustrates a video data structure 23 according to an embodiment of the present invention after a second recording. The same batch numbers refer to the same structures as in Figure 3A. The second recording, indicated by VTSTT_V0BS # 2 in the figure 27, is appended to the first 17 temporary review areas. The second recording is coupled with the corresponding control data 25 (MGT2-1, MGT2-2) and a second reserved area allocation table (RSAT-2). This RSAT-2 includes not only mapping the control data of the second recording 25, but also mapping the control data of the first recording 16. The RSAT-1 occupied area allocation table is therefore no longer used. As explained below, the occupied area allocation table contains a version number that indicates outdated versions.

As a result, 7 VTSTT_VOBS # 1, 17 TOS-1, VTSTT_V0BS # 2 and TOS-2 can be considered as continuous VTSTT_VOBS. The series may include sectors of unknown format for DVD players, but as long as they are not referenced by a program chain, • ···· '· β -, · ί : · · · .Γ,. ·· :?

······ ♦ · * * Do not disturb the operation of the players.

The program chain is used in the read-only DVD disc DVD video data structure to mark all or part of the title or menu. This defines the cells to be displayed, the cell being the base unit to be displayed. A cell consists of several video object units (VOBUs) and is part of a VOB.

Figure 3C shows a video data structure 28 according to an embodiment of the invention after the control information is updated without the need to change the corresponding VTSTT_VOBS. For example, a user can edit a record by causing only 13 VRMI changes. You may also need a new menu tab. so you don't have to change 7 or 27 VTSTT_VOBST.

The update only affects part of the first recording control data (MGTl-1, MGT1-2) because only part of the MGT1-3 is obsolete. The new version of MGT1-3, labeled MGT1-3 ', is recorded in the new temporary review area (TOS-3) attached to the previous 18 temporary review areas (TOS-2). TOS-3 includes MGT1-3 'and a new 31-Occupied Area Allocation Table (RSAT-3), which includes the updated, updated MGT1-3 (already outdated) mapping and MGTl-3' (exchanged). Thus, the previous 26 reserved area allocation table (RSAT-2) becomes obsolete by this time, as indicated by the largest version of the TOS-3.

Figure 3D shows a video data structure 32 according to an embodiment of the invention after completion of the finalization step. All 16, 30, 25 data controller data (MGTl-1, MGT1-2, • ·

- 13 - ........

MGT1-3 ', MGT2-1, MGT2-2) is copied to the occupied area 19, which also contains file system data such as UDF. In the remaining area 33 of the occupied area, which is not occupied by control data 16, 30, 25, any data is recorded. The inlet area 20 and the outlet area 21 are also fixed.

Note that copies of security file 14, 8 are in the last temporary review area 29 (TOS-3) and are not re-mapped. Including such files in the temporary review area increases the error-tolerant capability. After the last VRMI_BUP, there must be a second Volume Descriptor 34 (Anchor Volume Descriptor Pointer) as required by the UDF file system.

Fig. 4 shows an embodiment of the reserved area allocation table 18, 26, 31, which contains a maximum of one logic sector (2048 bytes).

The RSAT_ID 35 (4 bytes) contains a "RSAT-containing booklet.

The RSAT_COUNT 36 (1 byte) includes a decimal number denoting the version number of the reserved area allocation table 18, 26, 31. For the first time we record an RSAT, this field is set to zero. For each new version of RSAT, we increase the value of this field by one.

The 37 PREV_LOC (3 bytes) contains the logical sector number (LSN) of the location where the previous RSAT is located.

38 ITEM__N (1 byte) in the RSAT mapping table (RSAT_MAPT) indicates the RSAT__ITEMS (ITEM = item) numbers used.

• ·

RSAT_MAPT 39 (2032 bytes) contains RSAT_ITEMs, each of which is 8 bytes. The used RSAT_ITEMs 39 are placed in front of any unused 39 RSAT_ITEMs. All unused 39 RSAT_ITEMs are set to zero. The used 39 RSAT ITEMs allocate the recording area of the DVD between the LI and LO areas for ITEM_N mapping segments, each of which is a continuous logical sector series. The mapping segments are linearly mapped to an object segment of the same size.

The content of RSAT_ITEM 40 is a MAP_STAT (2 bit) 41 which indicates the mapping status of the segment that begins at ADDR_LOC 42 of this batch and terminates directly before the ADDR_LOC 42 of the next batch. If there is no next item, the mapping status remains the same for all subsequent logical sector numbers up to the last written sector.

Figure 4 shows the possible values of MAP_STAT 41 in the table. 00b (binary) indicates that the corresponding segment is not fixed and that the addresses are mapped to new locations. 01b indicates that the segment is reserved for a fixed segment, titles are mapped to new sites. 10b indicates that a segment is not fixed and that the locations are the same as the address locations. 11b indicates that the segment is fixed and that the target locations are the same as the address locations.

The ADDR_LOC 42 (3 bytes) contains the logic sector number (LSN) of the first sector of the mapping segment, such as the 16 ECC block sectors. In this case, see Figure 42

- 15 - ........

ADDR_LOC will be a multiple of 16. RSAT_ITEMs 40 increase as ADDR_LOC 42 increases.

Target_LOC 43 (target = object) (3 bytes) contains the logical sector number (LSN) of the first sector of the subject segment. The sector at ADDR_LOC + n is mapped to the sector at TARGET_LOC + n by n from 0 to ADDR_LOC (current) -ADDR_LOC (current) -1.

Fig. 5 shows an embodiment of a space allocation table 18, 26, 31 comprising three logical sectors. Where appropriate, reference numerals are used as in Figure 4. Such a similar item is 35 RSAT_ID (four bytes) and 36 RSAT_COUNT (two bytes).

The new RSAT_FMTID 44 (one byte) indicates that the application is using the RSAT format mode.

The 37 PREV_LOC (three bytes) is also similar.

The new 45 END_DATA (three bytes) is then added, which contains the logical sector number (LSN) of the last sector, which contains application data that we do not intend to place in the reserved area. When the RSAT FMT_ID 44 is set, the 45 END DATA is a UDF file system indicating the location of the second Volume Descriptor 34 (Anchor Volume Descriptor Pointer).

RSAT_MAPT_SA 46 (two bytes) contains the start address of the RSAT_MAPT 39 in bytes for the start address of the RSAT.

The RSAT_MAPTSZ 47 (two bytes) contains the size of the RSAT_MAPT in bytes.

«·· ·· ♦

The content of 39 RSAT_MAPT (two sectors) is 40 1024 RSAT_ITEM (four bytes). The RSAT_ITEM # n contains the mapping information in the occupied area 19 for the ECC block (n + 1).

MSTAT 48 (one bit) indicates the mapping status of the ECC block (n + 1) in the occupied area 19. 0b (b: binary) indicates that this ECC block is in use and lb indicates that this ECC block is mapped to another location. If MSTAT 0b, then no data is recorded for the logical sectors from LSN = (nxl6) to LSN = ((nx16) +15).

If MSTAT is equal to lb, then the LSN = (nxl6) to LSN = ((nxl6) +15) logical sector data is located at the places designated by ACTUAL_LOC 49 (three bytes) .

The ACTUAL_LOC 49 then includes the LSN of the first sector of the ECC block, where the data is actually recorded. The value recorded in 49 ACTUAL_LOC will be 16 multiples. The three least significant bits of ACTUAL_LOC 49 are always set to OOOb. If 48 is equal to MSTAT Ob, the value recorded in ACTUAL_LOC 49 will be OOOOOOh.

The example shown in Figure 6 shows the possible use of the reserved area allocation table (RSAT) in video applications 18, 26, 31. In the figure, the recording area 50 corresponds to a "real disk, and the recording area 51 corresponds to a" virtual disk "obtained by" mapping the real disk. "

In this example, "real disk is not finalized, so control information (13 VRMI, 3 VMG, 5 VTSI), their backup (8 VTSI BUP and 14 VRMI_BUP) and 52 file information" * _ 17 - ... .......

(UDF) is recorded as the last 7 VTSTT_VOBS (corresponding to the 16 Control Data (MGT) mentioned above).

The figure also shows the number 48 MAP_STAT and the LSN logic sector for each area. The recording area 51 corresponds to the occupied area 19 and forms a "virtual disk" obtained by "real disk mapping". The data between LSN = k and LSN = B after the finalization is recorded.

The table in Figure 6 shows the appropriate values for the MAP_STAT 41, the destination location (ADDRESSED), and the actual location (ACTUAL). MAP_STAT = 00b 41 indicates that, mapped and not fixed, 10b indicates that it is not mapped and not fixed, and 11b indicates that it is not mapped but is fixed.

Figure 7 shows a second example of a possible application of the occupied area allocation table (RSAT) 18, 26, 31 in a video application when a second recording is made. The recording area is the same as the "real disk, and the recording area 54 is the virtual disk" obtained by real disk mapping. This example differs from the example shown in Figure 6 in that the recording area 17 in the temporary review area (TOS) is kept as small as possible by controlling the control data 16 (MGT) side by side. Only select the appropriate locations (A, B, C, D) at the time of finalization between ap, q, r and s within the occupied area 19 (RÉS).

Fig. 8 shows a third example of a possible use of the reserved area allocation table (RSAT) 18, 26, 31, only when the video recording control information (VRMI) 13 is transmitted. The "real disk recording area," the corresponding recording area of the "virtual disk" is indicated by 56 batch numbers.

Due to the update, the previous 26 reserved area allocation tables (RSAT-1) are not used anymore, it is replaced by the next reserved area allocation table (RSAT-2). The RSAT-2 includes the old mapping that was in RSAT-1, except for the mapping of the old 26 VRMI, which we replace with the updated 27 VRMI mapping.

Fig. 9 shows an example of the arrangement of the reserved area allocation table 18, 26, 31. In this embodiment, FIGS

The area reserved for RSAT consists of the last two or three fixed 57 ECC blocks of the occupied area 19, each containing an RSAT 18, 26, 31. All of them are identical and are located before the first byte of the first sector of each ECC block 57. All bytes that do not belong to RSATs 18, 26, 31 are reserved and set to arbitrary values.

Figure 10 shows a recording method according to an embodiment of the invention using the occupied area allocation table (RSAT). The process can be performed by a general process processor running a user program, for example, by using an independent disk drive connected to the computer system. The method can also be performed with dedicated processing hardware, such as a disk drive built into a recording device. Some of the functionality can also be integrated into the drive itself.

In the first step 58, it is determined whether only a first record is made on an empty recordable disc. If so, in step 59 «« ·, the driver is instructed to create a reserved area 19 (RÉS) at the physical sector number PSN = 0003, which lasts up to PSN = 0003 3FF0h. In step 60, starting from the PSN = 0003 4000h, an audio / video information signal having an audio-video content of the first recording, such as an MPEG-2 program stream, is written. Recording stops at a sixteen sector boundary (with regard to the ECC block of sixteen sectors). The recorded stream satisfies the video object set for the address (VTSTT_VOBS) specification, which is defined in the rewritable DVD disc 12 DVD video data structure, as described with respect to FIG.

In step 61, all control data (MGTs) 16 are recorded after the recorded audio / video signal according to the requirements of the aforementioned specification. The 5 video address pool information backup files (VTSI_BUP), the 14 video recorder control information backup files (VRMI_BUP), and the second volume descriptor 34 are sequentially recorded in that order.

Finally, in step 62, an area of the reserved area allocation table (RSAT) 18, 26, 31, e.g., thirty-two of the forty-eight sectors, containing two or three instances of the reserved area allocation table (RSAT) 18, 26, 31, is attached .

Figure 3A shows the state of such a first recording.

If it is determined in step 58 or step 63 that a second recording is made, then in step 64, a second audio / video information stream, e.g.

we write a stream from the last written title after step 62. The area starting from the physical sector number PSN = 0003 4000h and lasting until the end of the second recording corresponds to the VTSTT__VOBS specification mentioned above. The previously written 16 control data (MGT) and the occupied area allocation table 18 (RSAT-1) are fully included in the new 27 VTSTT_VOBS.

Again, in step 65, all new control data 25 (MGT2) are recorded after the second recording, which is contained in the new set of 27 video object objects (VTSTT-VOBS # 2).

In step 66, a new 26 reserved area allocation table (RSAT2) is recorded, similar to step 62, and the version number is increased. The result is shown in Figure 3B.

In step 67, it is determined whether only one update of the control data (MGT) 16 has to be recorded. If so, then we record in step 68 a new version of VRMI 13, a backup of 14 VRMI_BUP, and, if necessary, 3 VMG files.

In step 68, a new second ADVP 34 is recorded after at least 14 VRMI_BUP. None of these are mapped to the correct RSAT. If necessary, a part of the file system data is rewritten in step 69. Finally, in step 70, an additional 31 RSAT-3 is added and the version number is increased to three. The result is shown in Figure 3.D.

If there is no need for update or fixation, it is necessary to determine in step 71 whether the current recording job should be closed or left open (step 72). If the work is left open, the disk contains a reserved area 19 (RÉS) and a temporary review area 17 (TOS).

If the job has to be closed, then in step 73 the control data 16, 25, 30 (MGT) is copied from the temporary review area (TOS) 17, 24, 29 to the occupied area 19 (RÉS) of the reserved area 18, 26, 31 allocation table (RSAT) mapping information. Then, in step 74, any data is recorded in all sectors of the occupied area 19 which are still not recorded after the previous recording step.

In step 75, the final second volume descriptor 34 (ADVP) is added to the end of the data structures. In step 76, the introductory area (L1) is fixed to the area requirements.

Finally, in step 77, the work is closed by recording the corresponding closing data. In this case, it is not possible to write more video content according to the DVD video data structures defined for the write-once disc, but it is still possible to add other data.

In another embodiment, the disc may be finalized by recording a disc outlet area (LO) 21 instead of closing data. In this case, no other data can be recorded.

The read-only DVD disc compatibility with DVD video data structures can only be achieved if the disk has an introductory area (L1) 20, all work is locked, and there is no blank area for the start area (L1) 20 and the outlet 21 area (LO) or the end of the last closure.

Fig. 11 shows a fastening device according to the invention. The recordable DVD 79 is rotated by a rotary drive 80 controlled by a servo motor control device 81. The servo motor control device 81 is also controlled by the optical write / read unit 82

positioning of the disc 79 on a track 84 focused on a reader / reader with laser beam.

The unit 82 includes a laser beam generating device and radiation detectors for converting reflected beams into electrical signals. The digital data expressed by the electric signals is stored in the buffer memory 85. Channel demodulation device 86 and error correction device 87 demodulate or improve channel coded information to obtain user data. User data is compressed in video data according to an appropriately compression format, such as MPEG2. Compression of the compressed user data is terminated by the decoding device 88 and converted into analog signals by means of an AD converter. Alternatively, the user data may be digitally removed and converted to a suitable transcoder 89.

Conversely, the received analog signals are converted to digital signals by a DA converter, and then compressed into MPEG2 format by an appropriate coding device 90, provided with error correction data by an error correction tool 91, and channel coded using a channel modulation device 92. Digital compressed signals may also be introduced via a second transcoder 100.

For DVD discs, channel modulation is EFM +.

A control device 93 can control individual units as well as inter-unit collaboration. To this end, the control unit includes a general processor 94, which is electronic read-only memory (ROM) 95, 96 direct • · · · ·· ·· ·· ··· ··· ··
