Description

1JZ4/00 IX. Description of the invention: [Technical field to which the invention pertains] = Structure related to the area formed in the data block ^(4) on the high-density read-only recording medium to ensure that the playback is compatible with the overwriteable recording medium [Prior Art]

In a disc category such as a compact disc (CD), the recorded media can permanently store the inter-density digital audio data, which is recorded; |: Japanese code and a fairly popular medium. In addition, a digital audio-visual disc (the pain in this article and the simple DVD) has been developed into a new disc-type recording medium. A DVD is left a 曰. 告 | > ^ 储谷谷 is much larger than cd, so at the same time quality animation or audio data can be recorded on a DVD for a longer period of time. The DVD is widely used. There are three types of DVDs, read-only DVD R〇m, single-write DVD R, and overwritable or DVD-R/w.

A high-density rewritable recording medium is called bd_re (Bliway Disc Rewritabie, which can overwrite Blu-ray discs), and its storage capacity is larger than the DVd set by the relevant company. As shown in FIG. 1A, a rewritable optical disk BDRE has some distinguishing regions composed of the following: a clamp region 丨, a conversion region 2, a burst cutting area (BCA) 3, and a lead-in area. 4. A data area and a lead area 5. The clamp region 1 is a central region, and the clamp of the optical disc device is used for inserting the rotating optical disc, and the conversion region is an information region, and the clamp region 1 is included in the clamp region 1 and includes the above-mentioned introduction region 4 and the above information. Between the regions. After the disc manufacturing process is completed, BCA 3 is used to add information to the disc. The import area 4 is the important information required for disc playback, and the export area 5 is where the disc end signal is written. The lead-in area 4 is divided into a plurality of areas; a first protection area, a PIC, a second protection area, a second type of information, an OPC, a reserved area, and a first type of information.

The first protected area is the protected area that prevents the BCA from overwriting the PIC. The P 1C zone is an area in which pre-recorded nicks are stored generally associated with the disc and various other information. The second protected area is a buffer for converting from the pre-recorded area to the rewritable area, and the first and second information areas are each used to store specific information related to the optical disc or application, such as control information.

Figures 1B and 1C show a RUB (recording unit block), which is defined in the disc standard in question. A single RUB corresponding to a single ECC (Error Correction Code) consists of a start zone, a solid cluster, an end zone, and a guard zone, as shown in Figure 1B. If many RUBs, or continuous RUBs, are created at a time to store real-time input data, for example, A/V data, a set of start zones, entities, and end zones are repeatedly created to the required number, and At the end, a protected area 'Gurar_3' is formed, as shown in Figure 1C. As shown in Fig. 2A, the starting area is protected by a 1100 channel bit area 1〇1^4_1' and a 1660 channel bit area ‘? 1 eight' composition. A copy of 55 20-channel bit patterns is written in the defense area 'Guard_l' to indicate the header of the RUB, and the first synchronization data 'Sync^l' and the second synchronization data 'Sync_2' are written in the front In the area 'PrA'. In its 6 1324766, Sync_l and Sync_2 have a length of 30 channel bits. Each sync data consists of a 24-bit sync body and a 6-bit sync ID. The synchronization IDs of the first and second synchronization data are each '000 100' (FS4) and 4010 000, (FS6) °

As shown in Fig. 2B, the end zone is composed of a 540-channel bit protection block ‘Guar d_2’ and a 564 channel bit post-content ‘PoA’. The PoA includes the third synchronization data 'SynC_3'. The third synchronization data is also composed of a 24-bit synchronization body and a 6-bit synchronization ID. Further, the synchronization ID of the third synchronization data is '000 001' (FS0). The protected area 'Guard_2' is created to prevent coverage between pre-recorded data and new data to be recorded. It also has a replica of 27 20-channel bit patterns to indicate the end of the pre-recorded area called the REB-only record. The user profile is written to the physical cluster and is restored to the original data by the signal processor using the clock synchronized with the synchronization data written in the start zone.

Figure 1D shows the detailed recording format of the physical cluster of BD_RE, where BD_RE is the location recorded by 31 recording frames (frames #0 to #30). The seven frame synchronization codes (FSs #0 to #6) which are different from each other are written in 31 recording frames in a predetermined unique order, as shown in Fig. 1D. The type and type of frame synchronization code shown in Figure 1E is written in a solid cluster. As shown in Fig. 1E, all seven frame synchronization codes are used and each frame synchronization code is composed of a 24-bit synchronization body and a 6-bit identification type. Each RUB corresponding to the aforementioned single ECC block has a physical address 7 1324766 information 'for example, an Address Unit Number (AUN) for random accessing a random RUB written to a BD-RE. After being modulated and encoded with the A/V information, the entity address information is written in one of the RUB entity clusters. In addition, an aun is derived from the physical block code (physical sect〇r number, PSN), in fact, the physical block code is not written in ^* BD - RE. Can only write once and overwriteable discs (DVD-R, -RW, -RAM, +R,

+ RW) Before the new material is recorded in a discontinuous manner with the previous record, the link frame is generated after the previous record area. However, a CD-ROM such as a DVD-ROM and a video CD does not require any link frame to connect two data blocks because it contains the complete record information. Despite the differences between writable and read-only discs, a conventional disc player such as a DVD-Player and a DVD-ROM is required to borrow additional entities and/or software for playing both types of discs.

Needless to say, a CD player capable of recording and playing a writable disc also needs to be equipped with additional physical and/or soft Zhao to play CD-ROM and writable discs. At the same time, the high density of 'called 'BD-ROM' The standard for reading-only recording media is also discussed with BD-RE. Incidentally, if the physical specifications of the BD-ROM are the same as those of the BD-RE, it is advantageous for the optical disc player to apply the same broadcast operation to the two types of recording media. In addition, they need to be distinguished and their format compatibility is guaranteed. Therefore, there is a need to adjust these conflicts. However, suitable adjustment methods have not yet been provided.

The first "continuous stroke" of the high density recording medium constructed in accordance with the present invention and the data recording method associated with the connection area, also referred to as data generation, will be described in detail later. In the following, the words "write" and "record" spear-(f〇rm)j have the same meaning for the read-only recording medium, and are generated in the connection area. The frame called the connection frame or the recording frame will fill in a note, and the material area will be recorded. The material area will play the adjacent implementation area and create a frame. 14 1324766 (1) Architecture of the connection area

A density-reading recording medium, for example, a BD-ROM constructed in accordance with the present invention has an entity format (consisting of a start region, a physical cluster, an end region, and a protected area) as described with reference to FIGS. 1 and 2 Further, FIGS. 1 and 2 illustrate a high-density rewritable recording medium. However, the areas of the bd-R〇M conforming to the format of the rewritable recording medium element may be individually named under different names. The start area of the embodiment, as shown in FIG. 3A, is composed of a protection area 'Guard_l' and a pre-position area "PrA", and the pre-area includes two synchronization data. Each synchronization data is synchronized by 24-bit. The body and the 6-bit synchronization ID are composed.

When the synchronization IDs of the preamble synchronization data in the BD-RE are '〇〇〇100' and '010 〇〇〇', as shown in FIG. 2A, the front of the BD-ROM constructed according to the present invention The area contains two synchronization data whose IDs are FSO('〇〇〇〇〇l')(Sync_3) and FSGrOlO 000')(Sync_2). In addition, the sync data 'Sync_3' is placed in the sync data 'SyncJ, before. Further, the rear area (PoA) of the BD-ROM end area constructed in accordance with the present invention, as shown in Fig. 3B, includes synchronization data having an ID of FS4 ('000 l〇〇') (Sync_l). There is a difference in that the synchronization data of the BD-RE with the synchronization ID FS0 ('000 001') is written in the area after the BD-RE. In the BD-RE, if two RUBs are generated, a pair of start area and end area are also generated as shown in Fig. 1C. The pair of start and end regions (pairs 15 1324766 should be in a connected area) contain three synchronized data having the order of 'Sync^l', 'Sync_2', and 'Sync_3'. Incidentally, the order of recording in the BD-ROM is £Sync_3', 'Sync_2', and 'Sync_l, which are opposite to the order of BD-RE.

Therefore, although the BD-ROM constructed in accordance with the present invention is similar to the physical recording format of the BD-RE, the writing order of the synchronized data in the connected area can be distinguished from the BD-RE in addition to the arrangement of the data. It is determined whether the existing area is the connection area of the BD-ROM. In the above embodiment, the start area, the end area, and the protected area 'Guard-3' may contain information similar to the record of the corresponding area on the BD-RE.

The structure of the BD-ROM connection area can be defined differently as shown in Fig. 4A showing the second embodiment of the present invention. As shown in Fig. 4A, the two connection frames of 'the same size 932 channel bits' in one example of the BD-ROM constitute a single connection area. In one example of BD-RE, the start area of 1104 bits and the end area of 2760 bits of different sizes constitute a single connection area. The two connection frames are in the same architecture and any frame is composed of 3 channel bits. The meta-frame synchronization gamma, the 9-bit entity address, the 114-bit tuple user data, and the 32-bit tuple parity are formed. The 114-bit user data can contain a variety of additional information, such as anti-piracy information (to prevent illegal copying of movies such as recorded on a BD-ROM to other media), control information (for servo control) For operation). 16 is called 4766. Fig. 4B shows a third embodiment of the present invention. The connection area on the third embodiment is composed of two equal-sized (1 932 channel bits) connection frames, and each frame is composed of a 30-channel bit frame synchronization code, a 9-bit entity position, and 146 bits. The composition of the tuple user data. The difference from the embodiment of Fig. 4 is that there is no parity.

Useful information can be written to the 146-byte user data space. The useful information is anti-piracy information (to prevent illegal copying of movies such as recorded on a BD-ROM to other media), or control information (for servo control operations). A fourth embodiment of the invention. The connection area on the fourth embodiment is composed of two equal size (1932 channel bits) connection frames, and each frame is composed of a 30 channel bit frame synchronization code '155 byte user data. Compared to Figure 4A, the difference between the embodiments of Figure 4C is that there are no physical addresses and parity bits. This embodiment also differs from Figure 4B because there is no physical address. Fig. 4D is a view showing a fifth embodiment of the present invention. Fifth embodiment

The connection area is composed of a 30-channel bit front frame synchronization code, a 3714 pass * *. A bit position connection, two 30-way units followed by a sync code - code and 40 and 20 channel bit lengths respectively. The two replica modules are composed. The 3714 channel bit connection is made up of three connection frames and 4 bits of 7L padding data. A connected area can have any possible architecture that is different from the above. The data is written in the physical cluster in the format of the ECC block, and the above seven frame synchronization codes FS0 to FS6 are usually used for the ECC block. 17 1324766 At least one of the two connection frames as shown in Fig. 4A uses the _frame synchronization code 'FS η' and its synchronization is different from the above seven frame step codes. The synchronization ID eFS of the new frame synchronization code is '1〇〇ioi' (FS7), '1〇1 〇i〇' (FS8), '〇1〇1〇1, (FS9), 001, (FS1〇 ), as shown in Figure 5. The selection of all four synchronization codes satisfies the conversion restrictions specific to BD-RE, that is, the bit module cannot be shorter than 2 bits.

In the recording embodiment of Fig. 4A, the frame synchronization code FS0 is nested in the first connection frame 'and the frame synchronization code 'FS η' is in the second connection frame. In addition, the data recorded in a BD-RE must satisfy the RMTR (Run-Limited Transition) limited by the J 7ρρ (parity reservation) adjustment. * This restriction is defined by BD-RE. Data record standard.

The restriction of the RMTR prohibition (to ensure stable measurement of the rf signal) is that the minimum execution length 2T' is '01, or '10, and cannot be repeated more than six times in succession. Therefore, it tends to use a frame synchronization code 'that is, '100 101, (FS7) or '101 001' (FS10) at a small switching frequency to achieve a bit transition that satisfies the limit in the new frame synchronization code. The use of the framework synchronization code will be explained in detail with reference to Figure 6A. The first condition shown in FIG. 6A is the first embodiment of the present invention. In the embodiment, the recording frames of two 1932 channel bits are recorded in a connection area, and each recording frame is composed of a frame synchronization code. , - physical address, user data and parity bits. At least one of the 18 1324766 of the two record frames contains the newly defined frame synchronization code 'FS η'. For example, the 'frame synchronization code 'FSO' and its identification module (ID) are written as the first frame synchronization code, and the identification module is '〇1〇101', '101 〇1〇' or '100 101' The new frame synchronization code 'FS η' is written as the second frame synchronization code.

When the synchronous recognition module is '010 101, '101 010, or '100 101', the new frame synchronization dai mai 'FS η' is used, the frame synchronizes the megabytes after the 'FS η' The address has an unscrambled start data '〇〇, as shown in Figure 6. This is because it helps to meet the RMTR condition of the 1 7ΡΡ adjustment code. The definition of the 17-inch adjustment code is for use as a material record on the bd-RE.

For example, if there is a synchronous identification module '1 〇〇1 〇1, the new frame synchronization code FS7 is used, and at the same time the physical address bit is η 01 11', which is shown in Figure 7D. The adjustment bit made by the 17Ρρ adjustment table is '010 101 010 101'', and the adjustment bit that finally contains the synchronization recognition module constitutes '100 101 010 101 010 101, where 2Τ module (one zero is in two neighbors) One of the modules) continues to appear 7 times. However, if the physical address includes '〇〇 in its header, the example of the above physical address becomes '00 01 1 1 01 1 1, and its 17ΡΡ adjustment bit becomes '010 100 101 010 101 '. Therefore, the final bit with the synchronous recognition module constitutes £1, 101,010,100,101,010, and a 3Τ and four 2Τ modules appear one after another. The second condition as shown in Fig. 6 is a second embodiment of the present invention. In this embodiment, a record frame of two 1932 channel bits is recorded in a connection 19 1324766 area, and each record frame is composed of a frame synchronization code, a physical address, user data, and parity bits. At least one of the two record frames contains one of the frame synchronization code FS10 ('101 001,), the newly defined frame synchronization code 'FS η'. For example, the 'identification module is t〇〇〇〇〇1, the frame synchronization code FS〇 is written as the first frame synchronization code, and the new frame synchronization code FS10 is written as the first frame synchronization code.

When the new frame synchronization code 'FS10' is used, the RMTR limit of the 17PP adjustment code used for data recording on BD:RE is automatically satisfied. Therefore, the subsequent physical address does not begin with ‘ 〇 〇. For example, if the identification module is '101 001, the new frame synchronization code FS10 is used, and the subsequent physical address bit is '〇1 n 〇1 11', which passes the 1 7PP shown in Figure 7D. The adjustment bit made by the adjustment table is '010 101 010 101', and the adjustment bit that finally contains the synchronization recognition module constitutes '101 001 010 101 010 101, in which a 2T, a 3T and 6 2T modes appear.

The third condition shown in Fig. 6B is the third embodiment of the present invention. In this embodiment, two recording frames of 1 193 channel bits are recorded in a connection area, and each recording frame is composed of a frame synchronization code '-physical address, user data, and parity bits. Composition. Both record frames contain the newly defined frame synchronization code 'FS η'. For example, the first and second frame synchronization codes utilize one of the following new frame synchronization codes, namely FS7 ('〇l〇 10Γ), FS8 (£101 〇1〇'), and FS9 ('100 101,). 20 1324766 When the new frame synchronization code FS7, FS8 or FS9 is used, the 9-bit entity address after the frame synchronization dai FS7, FS8 or FS9 has the unscrambled start data '〇〇, as in the first Figure 6A shows. All of the above are for the RMTR limitation that better satisfies the 17PP adjustment code used for data recording on the BD-RE.

When the new frame synchronization code FS7 ('l〇〇1〇1,) is used, by writing the physical address space after the frame synchronization code with the data instead of '0 1 11 01 1 ,, Can meet the RMTR limit. The fourth condition as shown in Fig. 6B is the fourth embodiment of the present invention. β In this embodiment, two recording frames of 1932 channel bits are recorded in a connection area' and each recording frame is synchronized by a frame. The code, a physical address, user data, and parity bits are formed. Both record frames contain the new frame synchronization code FS10 ('10 001,). When the new frame synchronization code 'FS10' is used for both data frames, the RMTR limit of the 17PP adjustment code used for data recording on the BD-RE is automatically satisfied. So, the physical address after each frame synchronization code is not

Start with 0 0 '. If the newly defined frame synchronization code 'FS η is used in the above situation, whether an existing area is in a connection area can be easily and accurately judged 'because the new frame synchronization code is different from the entity cluster. User. For example, when the combination of the frame synchronization codes is used to discriminate the existing area, 'because the combination of a frame synchronization code is composed of SFS η' and FS4 written in a connection area, each is written in the previous entity cluster. FS4 and FS2 of the 29th and 31st Record Frames (Record Frame #2 8 to #3 0) 21 2124766

It is a combination of FSn-FS4 or FSn-FS2' which is significantly different from the frame synchronization code written in a real set. Whether or not an existing area is in the area is precisely determined based on the combination of the framework synchronization codes. The seven scenarios described above are summarized below. If the appropriate limit is applied to the data to be written to a frame syncyma, then any other four frame sync codes can be used, for example, if an entity of the entity is written after the frame sync daima. With a header of '00', the framework codes FS8 and FS9 can be used unimpeded. In the special case where a physical address is not written, if a certain group 'for example, '08h' (0000 1000) is not scrambled after the frame synchronization, it is adjusted by 17PP from '〇8h' The bit key '〇〇〇100 100' is placed after the frame synchronization code to be able to use any new frame synchronization code FS7-FS10 without regard to the RMTR constraint. The framework synchronization code is used to write one of the four new frames to synchronize one of the two connection frames when a known frame synchronizes FS0-FS 6 in a connection frame. Needless to say, this new frame synchronization code is only used in the two connection frames as illustrated in Cases 3 and 4 of Figure 6B. If the selected frame from the new frame synchronization code 'FS η, at least is used to connect the frame, when playing recorded data from a BD-ROM disc player (as shown in Figure 9, by an optical reading and writing town 11 ' A t *7 charm current reading system 12 and D / A converter 13) can quickly r liver plexus after a true address, the sync bit surface can be 100 code code, such as one, light Whether the 22 pivots taken by the VDP are within the connection area or a data section (physical cluster), in a BD-RE, the '31 recording frames respectively include seven non-frame synchronization dailies. However, the seven framework synchronization codes are not sufficient to clearly define the 31 record frames' so the framework in the previous record framework is used to identify an existing record frame and a frame code in the existing framework. In other words, it can be framed by itself. The continuous synchronization of the synchronization code and the frame in the previous record frame Ν-1, Ν-2, and/or Ν-3 identify the recording frame 同. That is, although one or two previous codes Ν -1 and / or Ν - 2 are not detected, the last detected can be used to identify with its synchronization code and the record frame, for example, assuming The existing recording frame is the eighth one, that is, the recording frame whose frame synchronization code is FS1 shown in the 1D chart. However, the frame synchronization Fs! is also written in the frames #1, #23, and 24, so The existing frame is identified by the previously detected frame synchronization code. At present, the framework of the detection synchronization gamma FS1 and the previously detected frame codes FS4, FS1, and/or FS3 (in frames #6, #5, respectively) can identify the existing frame as the #7th. As mentioned above, since the frame synchronization code is used to identify the frame, it should be noted that the frame synchronization code sequence (from the previous data frame to the record frame in the connection area defined by the frame synchronization generation) is explained. Refer to Figures 7A through 7C. Figures 7A through 7C show the sequence of applicable frame codes in accordance with the present invention. Same as the step generation synchronization code step generation synchronization N-3 〇 #7 > code framed frame and #4 frame new frame detailed synchronization 23

Fig. 7A is a synchronization code pair of FS7-FS8 in the first " 7B and 7C diagrams shown in Figs. 6A and 6B, respectively, FS7_FS7 and the case shown in Fig. 6B. If FSO# pS7's frame synchronization code is used as shown in the μth picture, the frame synchronization code of the Portuguese N-1, N-2, and N-3 with the frame synchronization 玛 〇 〇 , , , , , , FS FS FS FS FS 'As shown in case (1). Planting frame #〇 corresponds to the first charge of a coffee. As shown in eaSe (2), the frame in the second column (four) is sequentially framed by the frame synchronization codes FS2, FS4 and FS4. The intermediate address unit of the frame corresponds. The frame synchronization codes of the three frames as shown in (10) and (3) are FSO, FS7/FS2. Therefore, frame #1 corresponds to 4, 位 细 、, or RU 位 兀 兀 or - RUB 4 . In addition, the framework of the three frameworks before Frame #2 is FS1 'FSO and FS7 / FS2, as shown in case (4). Frame #2 corresponds to the first or intermediate unit of a Rub. As in the case of {A, in the case of the symbol, the intermediate address unit of the two frames #〇RUB corresponds, and the body frame #3 1 (the first connection frame) according to the present invention has the same frame as the previous frame. The same synchronization code sequence. Therefore, it will be difficult to detect the connection area of the FSO and FS7 will not be an appropriate solution. In the following example, FS7 shown in Fig. 7B is used as an explanation; in case (1) of Fig. 7B, the frame before frame #〇 is the same as FS7/FS2, FS7/FS4. And FS2/FS4. And the first address of the frame #〇 is the flat or intermediate unit. As shown in case (2), - condition. The third • the general frame FS0 and the 丨 address list • the three #0 and a #1 front FS4 〇 unit step code so the frame and a ί design, the frame ¥, and the collection: . For example, the code is based on RUB. Frame #1 24 1324766 The previous frame synchronization is based on FS0, FS7/FS2. And FS7/FS4. Frame #1 is the first or intermediate unit of a RUB. In addition, as shown in case (3), the frame synchronization code before frame #2 is FS1, fs〇. And FS2. Frame #2 is also the first or intermediate unit of RUB.

However, as shown in the example of ‘8’ in Figure 78. According to the inventive design of the present invention, the first connection frame (frame #31) and the second connection frame (#32) have the same frame synchronization code sequence in the frame frame N and the frame N-3, and it is possible to define the connection area cause problems. However, if the two frameworks use two FS7's and the newly defined framework synchronization code FS7d is in the case of a debt-tested connection area, the problem caused by this situation of FS7-FS7 is no more than the case of FS0-FS7 in Figure 7A. It is serious. Figure 7C shows the implementation of FS7 and FS8. The frame synchronization code before 'frame#' as shown by ease(1) is fS8/FS2, FS7/FS4 and FS2/FS4. And frame #〇 is the first or middle of rub

Address unit. As shown in case (2), the frame synchronization code before frame #1 is FSO, FS8/FS2 and FS7/FS4. Frame #1 is the first or intermediate unit of the RUB. In addition, as shown in case (3), the frame synchronization code before frame #2 is FS1 'FS0 and FS7 / FS2» in sequence, and frame #2 is also the first and middle unit of rub. As shown in Figure 7C, before any framework, Fs? and fs8 are used to represent different previous frame synchronization code sequences, ie, the previous frame synchronization code order before any frame is unique, so the comparison is opposite to the When one of the 7A and 7B diagrams is connected, it does not cause a problem. 25 Thus the use of ys7*FS8 is a preferred embodiment of the connection zone constructed in accordance with the present invention. Further, the frame synchronization codes FS7 and FS8 satisfy the RMTR constraint as described above. Figure 8 is a flow chart of a method according to an embodiment of the present invention for playing a recording medium. If the connection area constructed in accordance with the present invention is loaded (S81), it is first used in the BD-rOM. The management information of the playback control is read into a memory cassette (S82). Since in general the management information has been written into a lead-in area, it is read by a read/write head in an initial preparation stage. Then, the main material is played under the control of the control unit (S83). During playback, check if the frame is detected - the sync code (S84). If it is detected, it is determined whether or not the synchronization code to be detected is a synchronization code written in the main data area (S85). If the synchronization codes FS0 to FS6 stored in a disc recording/playback element are compared with the detected synchronization code, the discrimination can be made. If it judges that the detected sync code is a sync code (FSO~FS6) written in the main material area (S86), playback continues. However, if it judges that the detected synchronization code does not belong to the synchronization generation (FS〇~FS6), it means that it is the newly defined synchronization code FS7 or FS8, an existing location is related to a connection area (S87)' and then again Check if it is in the first connection frame or in the second connection frame (S88). If in the first connection frame, the data after the frame synchronization of the frame is scrambled (S89). Otherwise, the existing position is related to the second connection frame' and then the data just after its frame synchronization code is scrambled (S90). 1324766 • Therefore 'a disc player is composed of an optical pickup 11, a VDP system U, and a d/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein, It is possible to more accurately detect the user data and the physical address in the first and second connection frames (record frame #k+1, Zhuang + 2) of the BD-ROM. In particular, if the user profile contains useful information about anti-infringement or servo-control, use CD-ROM playback to perform appropriate operations on useful information. As described above, whether an existing location (on which an optical pickup is located) is located within a connection area or a main data area, and can be easily and quickly obtained by detecting and comparing with a new frame synchronization code. know. (2) Physical address As in the connection frame structure shown in Fig. 4A, one physical address is written in each of the recording pivots of the connection area shown in Fig. 1A, and there are three cases. In the first case, the AUN closest to the physical cluster #k+i is written after the frame is written in both connection frames. The second case is the closest physical cluster AUN that was written before the framework. Φ The second case 'AUN of the closest physical cluster before the first connection frame is written to the first connection frame, and the AUN closest to the physical cluster #k+l after the second connection frame is written to the first Two connection frames. The physical address (composed of the address of the 4-byte, the reserved parity and the parity of the 4-bit group, as shown in Figure nA) is ruled by 3 (9, 5, 5). After encoding, it has error recovery capability for use by a BD-RE. The process of making _bits-bits with error resilience will be detailed later. Therefore, a disc-playing machine consists of an optical head u, a 27 1324766 VDP system 12, and a D/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein. It is possible to more accurately detect one of the user data and the physical address in the first and second connection frames (record frames #k+1, #k+2) of the BD-ROM. In particular, if the user profile contains useful information about anti-infringement or servo-control, use CD-ROM playback to perform appropriate operations on useful information.

In the connection frame structure shown in Fig. 4D, one physical address is written in any of the three recording frames of the connection area shown in Fig. 1B, and there are two cases. In the first case, the AUN closest to the physical cluster #匕+1 after writing the frame in the three connection frames. The second case is written to the closest entity cluster # in the front of the framework. The physical address (consisting of the address of 4 bytes, the reserved 1 byte and the parity of 4 bytes, as shown in Figure 11A) is encoded by RS (9, 5, 5) 'With error recovery capability, for a BD-RE. The process of making an address error resilience will be detailed later.

Therefore, a disc player is composed of an optical head π, a VDP system 12, and a D/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein, More precisely, one of the user data and the physical address in the three consecutive connection frames (recording frame #k+布+2, κ+3) of the BD-ROM is detected. In particular, if the user profile contains useful information on anti-copyright or lexical-control, use CD-ROM playback to perform appropriate operations on useful information. Figure 10C is not another embodiment of the present invention, which writes a single address in the recording framework. These connection frames (record frames #k+1, #k + 2) 28 1324766 contain a 9-bit entity address, which in turn contains the real address of the 4-bit group. The real address of a 4-bit tuple may have 16 AUNs #0~#15 of the same value, which is written in the physical cluster before or after the connection frame.

A 4-bit real address of a physical cluster written in front of the first connection frame is a 27-bit address, and a 4-bit sequence code (0000~ used to indicate its order in the physical address) 111 1) and 1 bit fixed value '0', as shown in Figure 10C. All 27-bit addresses written to the previous physical cluster have the same value. Another 4-bit real address of the physical cluster written after the second connection frame is a 27-bit address, and a 4-bit sequence code (0000) indicating its order in the physical address. ~11 1 1) and 1 bit fixed value '0', as shown in Figure 10C. The 27-bit address of all the physical clusters written after it has the same value.

As mentioned before, the real address of the 4-byte of the first connection frame includes a single address, which is written in the previous physical address. For example, the real address of the 4-byte of the first connection frame has the address value of the nearest 16th AUN (AUN #15), and the AUN is composed of 27 bits and '11110', as in 10C. The figure shows. In this case, the last bit '0' of the five-bit '11110' written to the first connection frame can be replaced, thereby indicating that a physical address is written into a connection area, instead of A physical cluster. In addition, the real address of the 4-byte of the second connection frame includes a single address, which is written in the previous physical address. For example, the real address of the 4-byte of the first connection 29 1324766 frame has the address value of the closest first AUN (AUN#0), and the AUN consists of 27 bits and '00000, such as Figure 10C shows. In this case, the last bit 10' of the five-bit '00000' written to the first connection frame can be replaced by ς1', thereby indicating that a physical address is written into a connection area, and Non-physical clusters. The last five bits of the 4-bit real address written to the first connection frame may be '〇〇〇〇〇', and the last five bits of the 4-bit real address written to the second connection frame may It is '11110'.

In addition, an address written into a physical cluster may be written in the first and second connection regions, and the physical cluster is one of the physical clusters located before or after a connection region, as described in the previous section of FIG. Said. (3) Scrambling

Figure 11 is a flow block diagram of the connection frame of the structure shown in Figure 4. The flow of the framework of the connection framework includes scrambling 10 and adder 20. The scrambler 10 scrambles the user data of the 1 1 4 tuple with the physical address of the 9-byte tuple so that its DSV (digital sum value) approaches zero and is used after scrambling. Add a 9-bit entity address zero before the data. The adder 20 adds the 32-bit block parity from the scrambler 10 and the 20-bit bit frame synchronization code preceding the user address of the added address to the user data of the added address. Thus, a complete recording frame is constructed which contains 114 bytes of user data, and the 114-byte user data is scrambled with a 9-bit physical address. In terms of scrambling of user data, information other than a physical address of a 9-byte can be used. 30 1324766 Figure 11B is a block diagram of the connection frame for the frame structure shown in Figure 4D. The connection framework is structured by the process 1 and the adder 20, . The scrambler 1 以·a user data of 62 octets with a 9-bit address (eg, anti-infringement copyright ^ scrambled) to bring its DSV (digital sum value) closer to zero and the user The data address of the 9-bit tuple is added before the data. After adding the self-scrambling device, the 32-bit tuple is added to the user data of the added address. Therefore, the record of the complete group is formed. The framework includes user data of 62 bits and 70 groups of a 9-bit real frequency. The scrambling aspect of the user data can use information other than a 9 entity address. Conversely, the construction includes the frame synchronization code. , 9-bit address I, 4-byte user data, and 32-bit group connection framework, as shown in Figure 4A, can construct an entity with frame synchronization code, 9-bit tuple The address is a 1-bit tuple and a 4-bit tuple check digit, and 46 user data, such as Figure 4B or Figure 12A. The user data of the group can be scrambled. And the 4-bit body address can be used as a scrambling record. That is, in the scrambling process, '4 A portion of the tuple's physical address element (AddO~Add31) is used as an initial load value for a 16-bit meta-recorder 101, as shown in Figure 12B. Parallel load initial load in the recorder 1 0 1 After the value, each bit transfer process further includes the scrambled entity bit information) to the even parity bit in the scrambling, the integer bit parity block of the 103 body address scrambling tuple, including the reservation The tuple of the Μ 6-bit real 32-bit conversion is placed on the conversion and exchange output 31 3124766 scrambling bytes.

Since the user profile has a length of 146 bytes in the embodiment of Fig. 9, every 146 conversions are loaded in parallel with the conversion register 101 as part of the physical address. Some of the addresses to be loaded vary depending on the connection area. After parallel loading, 146 scrambling bytes (S0~S 145) are created and are "mutually exclusive or gated" 102 with 1 46 consecutive bytes of user data (D0~D 1 45) ) "Exclusive or". Thus, the successive 146 bytes that were scrambled as before were written into the connection frame. In addition to the physical address, some portion of the frame synchronization code module or a copy of the bit '1' can be used as a scramble key to optimize the user data. Furthermore, in addition to writing one of the physical addresses in the connection frame, one of the 16 addresses can be used, which is included in a physical cluster before or after an existing connection frame. In particular, of the 16 addresses, an address closest to the existing connection frame is used. A physical address to be written to a connection frame can be scrambled along with the user data written to it.

In another embodiment of the invention, it is not possible to write a physical address in the connection frame as shown in Figure 4C. In this case, a physical address before or after the connection frame is used as a scramble key, that is, an initial load value stored in the conversion register. Since the user data length is 155 bytes in this embodiment, every 155 conversions, the same or different physical addresses are used as an initial value to load the conversion register. As shown in Figure 13, a portion of the 4-bit address (Add#0~#3 1) is loaded into a 16-bit conversion register 10Γ of a scrambler in parallel, the disturbance 32 1324766

The frequency converter is also applicable to the recording of the BD-RE, and then 155 8-bit scrambling byte groups (SO~S 154) are sequentially output during the bit conversion process. The contiguous 155 scrambling bytes (SO~S154) are "interconnected" by a "mutually exclusive" 102' with a continuous number of 55 user bytes (D0~D1 54). Therefore, 155 scrambled user data (〇'0~154) are produced and they are written into the recording frame of a connected area. In addition to a physical address, a copy of the frame sync code module or a copy of the bit '10' can be used as a scramble key to scramble the usage data. (4) Filling data When the anti-infringement copyright or the useful data of the servo control is not written into the messenger data space, although the connection area of one BD-ROM forms two recording frames to ensure compatibility with the playback of the BD-RE, it is possible The user data space is filled with an arbitrary (eg, '00h') as shown in FIG. 14A. A fill value such as a series is called a fill data. If the same data is filled in the entire user data space, the process of a BD-ROM can be simplified more. Incidentally, crosstalk may occur if the neighbors have the same bit module. Thus, as shown in another embodiment of the fill data, certain values (eg, 'OOh', ς011ι' c 10h5 > £llh', 'FFh', 'AAh', etc.) are sequentially written to the messenger. In the data space, as shown in Figure 14B, to reduce the possibility of crosstalk. In the embodiment of the padding data record, the padding data of different values is recorded in the record frame of each connection frame deployed in a BD-ROM, and the decrement or the scrambler uses the value of the magnetic charge, and the energy consumption is less 33 1324766

The possibility of forming the same recording module between adjacent tracks is less likely to occur. The connection area of one BD-ROM forms the playback compatibility of the two BD-REs. According to another embodiment of the present invention, the user data spaces '01' and '11' are filled with any of the different values, and the padding data recording embodiment in which the first 4 C picture is alternately displayed as shown in FIG. 14C is used. There is the same data in the data space, and the adjacent data is filled. In this embodiment, the possibility of forming a phase between adjacent magnetic tracks is small, and therefore, the possibility is reduced as compared with the embodiment of Fig. 4A. The BD-ROM of this embodiment is simpler. In addition, if a value (e.g., '0 0 h ') is scrambled with a physical address, filling the entire user is large enough to eliminate crosstalk. After the scrambling, '〇〇h' fills the users, and if an unscrambled '08h' is placed before each use, then any of the above-mentioned new frameworks can be utilized. 7PP adjusts the RMTR limits specified. (5) Construction of ECC block If the user data space is written with useful and coded by channel coding to ensure its reliability, the (248, 216, 33) coding system is used as the channel coding method. Therefore, the framework is greatly reduced to ensure that, for example, the connection area of the connection area of the '〇〇' and the first connection area is different, the crosstalk occurs more than the 14B Change the data space of each connected area, and also the situation of the material space of the material space, without worrying about the important information, RS (62, 30, 33) and. The coding system 34 1324766 is also set to encode user data for a BD-ROM physical cluster. Figure 15A shows an embodiment of a record in which the data is recorded in the connection area constructed in Figure 4D. To record useful data as shown in Figure 15A, the RS (62, 30, 33) system first encodes the useful data for the 30-bit tuple, which creates a 32-bit parity.

For operation, a memory sequentially stores the input data to organize a 30x3 09 data block. When a 30x309 data block is organized, each column (151) is scanned sequentially. The RS (62, 30, 33) encoding system produces a 32-bit parity bit, and all operations scan the column and attach it there. Finally, a 62-tuple data sequence is structured. Each 62-bit tuple containing parity bits can be scrambled. If scrambling is performed, one of the physical address portions can be used as a scrambling record as described above.

Second, add a 9-bit entity address before the 62-bit tuple consisting of the above process. The physical address of the 9-bit tuple can here consist of a real entity address and a parity bit. For example, a 9-bit entity address can consist of a 4-bit real address, a reserved 1-byte, and a 4-bit parity. In addition, 145-bit stuffing data is added to the 71-bit tuple containing the physical address, which is then encoded by the RS (248, 2 1, 6, 33) system. This increases the parity of the 32-bit tuple. Finally, the padding data of the added 145-bit tuple is removed to generate a data unit of 103 bits to be written to the concatenation area. 35 1324766

The above operation is repeated for the useful data of the next 30 bytes to generate a continuous 103-bit data unit. After the three cells are manufactured, the three cells are followed by 4 padding bits, and then a total of 2 4 6 7 bins are subjected to a 17-inch adjustment. After the 17ΡΡ adjustment, the 2467 bits were expanded to 3,714 channel bits. The adjusted 3714 bit, and the second 30-channel bit frame synchronization code are placed into the first frame synchronization code of 30 channel bits, and the 40-channel bit repeats the bit module, repeating The third 30-channel bit frame synchronization code of the bit module and another 20 channel bit are sequentially added to the adjusted bit. The 3864 channel bits thus generated are written to a connection area.

If the useful data is too small to fill one of the above single connection areas, padding data is added to the piece of useful data to reach 30 bytes. For example, to write a useful piece of 3-byte, one of the three-tuples in each connected area inevitably has to constitute a single data unit. Therefore, as shown in Fig. 15C, a 30x309 data block, a straight block of a 309 byte is only written in one row and the other 209 columns are all filled into the padding data. It means that in each of the straight-line fields, the 29-bit stuffing data is added to the 1-byte useful data. Finally, an RS (62, 30, 33) encoding system is used to fill each of the added 30-bit bytes to add a 32-bit parity to the parity. To recover the useful information previously written to the connection area, an interpretation process can be performed in the reverse order of the write process as explained above. If the two identical frames form a single connection area as shown in FIG. 4B, the user data of the connection frame can be filled with the useful data of 114 bytes shown in FIG. 4A and the parity bits of the 32-bit 36 1324766 group. space. In the recording embodiment of Fig. 4A, a different method described in Fig. 4B or Fig. 4C is used for channel coding to ensure the reliability of the data. See Figure 16 for a detailed description of the different methods.

First collect useful information up to 2048 bytes (S1). A 4-byte EDC (Error Detection Code) is attached to a useful data block (S2) consisting of the 2048 collected bytes. The 2052 bit elements of the EDC are grouped into eighteen 11 4-byte data units (S 3). The first data element is scrambled (S4), and the physical address of the 9-byte is added to its head (S5). The padding data of 93 bytes is added to the data unit of the 123-bit tuple containing the physical address and is encoded by the RS (248, 2 16, 3 3) system, so that the parity of the 32-bit tuple is used. The bit is appended to the data unit. The 93 additional bytes are removed to produce 155-bit frame data (S 6), which is then adjusted by 1 7PP. Finally, the above-mentioned 30-channel bit frame synchronization code is added to the frame data to complete the connection frame of 1932 channel bits (S7).

One of the above series of processes (S4-S7) is applied to the data unit of the 114-bit block that is subsequently cut to make another connection frame. The resulting two connection frames are written into a connection area, and finally the structure shown in Fig. 4A is formed. When scrambling the above process for each 114-byte data unit, a physical address is used for scrambling as described above. The same or different physical addresses (written in RUBs before or after the connection area) are used to connect the first and second connection frames of the area. If 37 1324766 is used for a different address, the first connection frame writes an address before using a connection frame, and the second connection frame uses the address frame to write an address of 2 after the connection frame. As previously mentioned, the physical address written in each connection frame can consist of a 4-bit real bit & a reserved i-bit tuple, and a 4-bit tuple parity bit. In this case, the 4-bit tuple parity is generated by applying the channel coding system RS (9, 5, 5) to the 5-bit tuple. * In addition, the real address of the 4-byte is composed of a 5-bit address identifier and a 27-bit address for the resolution of the individual entity address in the connection area. A pair of '〇〇〇〇〇/11110' or '〇〇〇〇1/11111 can be used as the address identifier. If the former (or the latter) is used, "00000, (or t00001,)) is inserted into one of the physical addresses in a connection frame, and '1110, (or '11111') is inserted in the other connection frame. The above content enables the description of the new frame synchronization code 'FS η, which is different from the synchronization code 'FS〇 to FS6' used for the data frame written to the entity cluster). If a new framework is used, which is different from the synchronization code of the data frame, the frame synchronization code in the connection framework is used to translate the data written in the physical cluster into a password, so that the digital content recorded on a BD-ROM is exempted from Illegal copying. Although a data content recorded on a BD-ROM with such a translated password is copied to a rewritable optical disc, for example, BD-RE, the new frame synchronization generation mother's FS η in the connection frame is not copied to a BD. Above -RE and not generated during BD-RE recording. That is, the key that has been used for encoding cannot be obtained during the period in which the content is copied in 38 1324766 BD-RE, so it is impossible to decode it. Therefore, it is possible to protect the contents on one BD-ROM from illegal copying.

The above construction of a medium-density recording medium connection area according to the present invention ensures compatibility with a rewritable recording medium such as a BD-RE when played for a disc player or a disc player. Further, in the case of a disc player or a disc player, the structure of the connection area of the present invention can be implemented by quickly distinguishing a readable recording medium from a rewritable medium, if necessary. Operation. Further, it is possible to reliably store useful information in a connection area by the above-described recording method. Although certain specific embodiments of the invention have been disclosed, it is noted that the invention may be embodied in other forms without departing from the spirit of the invention. The present embodiments are therefore to be considered in all respects The scope of the invention is intended to be included within the scope of the appended claims.
