Description

丄32470:) IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a high-density read-only recording medium formed on a data block. The playback can be compatible with a rewritable recording medium. [Prior Art] A disc type recording medium such as a compact disc (CD) can permanently store high-density digital audio material, so it is a fairly popular medium. In addition, a number of audio and video discs (herein referred to as DVDs) have been developed into new disc type recording media. A DVD has a much larger storage capacity than a CD, so high-quality animation or audio material can be recorded on a DVD for a longer period of time. Therefore, DVD is widely used. There are three types of DVD, read-only DVD-ROM, single-drive n v Γν γ»

DVD-R, and rewritable dvD-RAM or DVD-R/W. Recently, the recording media that can be overwritten by the same ancestor is called bd-RE (Blu-ray Disc Rewritable), and its storage capacity is larger than that of the general DVDs established by related companies. As shown in FIG. 1A, a rewritable optical disk BDRE has a distinction area composed of the following: a clamp area 1, a conversion area 2, a burst cutting area (BCA) 3, an introduction Area 4, a data area and a lead area 5. The clamp region 1 is a central region, and the optical disc equipped with the tongs is used for inserting a rotating optical disc, and the conversion region is an information region, which is between the 5 1324765 clamp region 1 and the introduction lead region 4 and the above Between data areas. 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 protected area, a PIC, a second protected 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 PIC area 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 region, a solid cluster, an end region, and a guard region, as shown in Fig. 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 start zone is composed of a protected area 'Guard_l' of 1100 channel bits and a preamble area 'PrA' of 1660 channel bits. 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 pre-region' Among PrA'. In its 6 1324765, 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 1 00' (FS4) and ‘01 0 000’ (FS6) °

As shown in Fig. 2B, the end zone is composed of a 540 channel bit protection block sGuard_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. The synchronization ID of the third synchronization data is 4000 00r (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 channels of 0 0 channel bits to indicate the end of the pre-recorded area called the record only RU B. 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~#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 foregoing single ECC block has a physical address 7 1324765 information, for example, an Address Unit Number (AUN), which is used to randomly access a random RUB written in a BD-RE. After being modulated and encoded with the A/V information, the entity address information is written in a physical cluster of a RUB. In addition, an AUN system is derived from a physical sector number (PSN), and in fact, the physical block code is not written in a BD-RE. Can only write once and overwriteable discs (DVD-R, -RW, -RAM, +R,

In + RW), a link frame is generated after the previous record area before the new material is recorded discontinuously from the previous record. 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. Despite the differences between writable and CD-ready discs, a conventional disc player, such as a DVD-Player and a DVD-ROM, is required to equip additional physical and/or soft boats for playing both types of discs.

It goes without saying that a CD player capable of recording and playing a writable disc also needs to be equipped with additional physical and/or software to play CD-ROM and writable disc. At the same time, the standard of high-density CD-ROM called 'BD-ROM' is also discussed with BD-RE. Incidentally, if the physical size of BD_RC)M is the same as that of BD-RE, it is advantageous for the optical disc player to apply the same broadcast nasal 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.

In addition, the AUN i framework (each bucket) is connected to a user data space of a recording frame 12 1324765. [Embodiment] In order to make the present invention fully understandable, the preferred embodiments will now be described by the accompanying drawings.

First, the connection area 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 the data generation method, will be described in detail later. Hereinafter, the words "write", "record", and "form" have the same meaning for a read-only recording medium. In addition, a frame generated in the connection area is called a connection frame or a recording frame. (1) Architecture of the connection area

A high-density read-only 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, Fig. 1 and Fig. 2 show a high-density rewritable recording medium. However, the areas of the BD-RO that conform to the format of the rewritable recording medium element may be individually named after different names. The start area of the first embodiment of the present invention, as shown in FIG. 3, is protected by a protected area 'Guard_l' 'and a pre-arranged area' PrA', and the pre-arranged area contains two synchronized data. Each sync data consists of a 24-bit sync body and a 6-bit sync ID. When the synchronization IDs of the preamble synchronization data in the BD-RE are each '000 13 1324765 100, and '010 000', as shown in FIG. 2A, the front area of the BD-ROM constructed according to the present invention includes two Synchronous data 'its 1Ds are FS〇r〇00 001,) (Sync_3) and FS6 ('010 〇〇〇,) (Sync_2). In addition, the sync data ‘Sync_3 is placed before the sync data 'sync_2’.

Further, the post-region (PoA) of the end region of 81)_11014 constructed in accordance with the present invention, as shown in Fig. 3B, contains the synchronizing data having the ID FS4 ('〇〇〇100') (Sync-1). There is a difference, that is, synchronization in BD-RE. The synchronization data with ID FS0 ('000 001,) is written in the area after a BD-RE. In the BD-RE, if two RUBs' are generated and a pair of start area and end area are also generated as shown in Fig. C. The pair start and end areas (corresponding to a connection area) contain three pieces of synchronization data having the order of 'Sync_l', 'Sync_2' and 'Sync_3'. Incidentally, the order of recording in the BD-ROM is 48丫11〇_3', 'Sync_2' and 'Sync_l'' 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, it is also possible to synchronize the arrangement of the data and easily determine whether the existing area is the connection area of the BD-ROM. In the above embodiment, the start area, the end area, and the protection area ςGuard_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 in a different manner as shown in Fig. 4A of the second embodiment of the present invention. As shown in Figure 4A, at 14 1324765

In one example of a BD-ROM, two connectors of the same size (1932 channel bits) constitute a single connection area. In the case of the BD-RE, the start area of the 1104-bit and the end area of 2760 bits constitute a one-connection area. The two connection frames are in the same architecture and any frame consists of a 30-pass frame synchronization code '9-bit entity address, 1 1 4-bit data, and 32-bit parity bits. . The 1 1 4 user data can contain a variety of additional information such as anti-piracy information (to prevent illegal copying of movies such as recorded on BD-ROM to other media), control information (for servo For the operation of the system). Fig. 4B shows a third embodiment of the present invention. The connection area of the third embodiment is composed of two equal-sized (1932 channel bits) connection frames, and each frame is composed of a 30-channel bit frame synchronization code, a 9-tuple physical position, and a 1 4 6-bit element. The composition of the user data. The difference in the embodiment of Figure 4B is that there is no parity bit compared to the 4A map. Useful information can be written between the 146-byte user data. This useful information is anti-piracy information (to prevent illegal copying of movies such as recorded on a BD-ROM to other media), or to control funds (for servo control operations). Figure 4C shows a fourth embodiment of the present invention. The connection area of the fourth embodiment is composed of two equal-sized (1932 channel bits) connection frames, and each frame is composed of a 30-channel bit frame synchronization code and 1-bit user data. Compared with Figure 4A, the frame of Figure 4C is small and the single tracker controls the position on the empty space. 55 15 1524765 Fine • The difference is that there is no physical position Wei Wei ® address and parity The location of the body is different from that of Figure 43. This embodiment is also due to the case of the national corpse. The connection region on the fifth embodiment is composed of a 30-channel bit 亓^· L3-彳疋 框架 frame synchronization code, a connection portion of 3714 channel bits, two 3G channel bits, and a synchronization code of 4 分别 respectively. And two replica modules of 2 channel lengths.

- The connection portion of the 3714 channel bit is composed of bit stuffing data. A connected area can be a possible architecture of content. The three frame frames and the four frame synchronization codes FS0 to FS6 are generally used for the ECC block by the three connection frames and 4 in any format different from the above data in the ECC block format. At least one of the two connection frames as shown in Fig. 4A uses the new frame synchronization code 'FSn,' and its synchronization 10 is different from the above seven frame synchronization codes. The synchronization ID 'FS N of the new frame synchronization code is '1〇〇101' (FS7), '101 〇l〇' (FS8), {010 101' (FS9), '... OOI' (FSIO), as in Figure 5 shows.

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 F S 0 is written 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) j limited by the 17ΡΡ (parity reservation) adjustment. This restriction is defined by the BD-RE. 16 UZ4/65 material record standard β

The prohibition of RMTR (to ensure stable detection of RF signals) is a minimum execution length of 2T, which is ‘〇1, or '10, cannot be repeated more than six times in succession. Therefore, it tends to use a frame synchronization code with a small conversion frequency 'that is '1〇〇1〇1, (FS7) or '101 001, (FS10) in the new frame with the # code_ reaching the limit Meta conversion. The use of the framework synchronization code will be explained in detail with reference to Figure 6A. The first case shown in FIG. 6A is the first embodiment of the present invention. In the embodiment, the recording frames of two 1 392 channel elements are recorded in a connection area, and each recording frame is composed of one The frame synchronization code, a physical address 'user data and parity bits. At least one of the two record frames contains the newly defined frame synchronization code 'F S η,. For example, the frame synchronization code TSO, and its identification module (ID) are written as the first-frame synchronization code, and the identification module is '010 101, M01 010'

Or the new frame synchronization code 'FS η' of '100 101' is written as the second frame synchronization code. When the synchronization identification module is '010 101, '101 010, or '100 101', the new frame synchronization code 'FS η, when used, the frame synchronization code 'FS η, the next 9-bit entity address There is an unscrambled starting data '〇〇', as shown in Figure 6. This is because it helps to meet the RMTR condition of the 17ΡΡ adjustment code. The definition of the 17-inch adjustment code is for use as a record on the BD-RE. For example, if a new frame synchronization code FS 7 with a synchronization identification module 1 1 0 0 1 0 被 is used, while the subsequent physical address bit is '0 1 1 1 17 1324765 01 11', it is via The adjustment bit made by the 17PP adjustment table shown in Fig. 7D is ' 0 I 0 I 0 i 0 1 0 1 01 ', and finally the adjustment bit including the synchronization recognition module constitutes '100 101 010 101 010 101' The 2T module (a module with one zero between two adjacent ones) continues to appear 7 times. However, if the physical address includes '0 0 ' in its header, the example of the above physical address becomes '00 01 11 01 11', and its 17PP adjustment bit

It becomes ‘010 100 101 010 101’. Therefore, the final bit having the synchronous recognition module constitutes '100 101 010 100 101 010 101'. Among them, a 3 T and four 2 T modules appeared one after another. The second condition as shown in Fig. 6A is the second embodiment of the present invention. In this embodiment, a recording frame of two 1 392 channel bits is recorded in a connection area, and each recording frame is composed of a frame synchronization code, a physical address, user data, and parity bits. . At least one of the two recording frames includes the frame synchronization code FS10C 101 001'), one of the newly defined frame synchronization codes 'F S η '.

For example, the frame synchronization code F S 0 of the recognition module of '0 0 0 0 0 1 ' is written as the first frame synchronization code, and the new frame synchronization code FS10 is written as the second frame synchronization code. When the new frame synchronization code 'FS10' is used, the RMTR limit of the 17-inch adjustment code used for data recording on the BD-RE is automatically satisfied. Therefore, the subsequent physical address does not begin with ‘ 〇 〇’. For example, if the new frame synchronization code FS10 of the identification module is '1 0 1 0 0 1 ' is used, and the subsequent physical address bit is '01 11 〇1 11, which is shown in Figure 7D. The adjustment bit 18 1324765 made by the 17ΡΡ adjustment table is ' Ο 1 Ο 1 Ο 1 Ο 1 Ο 1 Ο 1 ', and finally the adjustment bit including the synchronous recognition module constitutes '101 001 010 101 010 101', wherein A 2 Τ, a 3 Τ and 6 2 Τ ' modes appear.

A third condition as shown in Fig. 6 is a third embodiment of the present invention. In this embodiment, the recording frames of the two 193 channel bits are recorded in a connection area, and each record frame is composed of a frame synchronization code, a 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 ('010 10Γ), FS8 ('101 010,) and FS9 (£ 100 101,). When the new frame synchronization code FS7, FS8 or FS9 is used, the 9-bit entity address after the frame synchronization code FS7, FS8 or FS9 has the unscrambled start data '〇〇', as shown in Figure 6A. The above is shown to better meet the RMTR limit of the 17-inch adjustment code used for data recording on the BD-RE.

When the new frame synchronization code FS7 ('100 }01') is used, the RMTR can be satisfied by writing the physical address space after the frame synchronization code with the data instead of '01 1 1 01 Π ' limit. The fourth condition as shown in Fig. 6B is the fourth embodiment of the present invention. In this embodiment, two recording frames of 1 193 channel bits are recorded in a connection area, and each record frame is composed of a frame synchronization code, a physical address 'user data, and parity bits. Composition. Both record frames contain the new frame synchronization code FS10 (M0 001'). 19 1324765

When the new frame synchronization code 'FS10' is used for two RMTR restrictions that automatically satisfy the & used for data recording on the BD-RE. Therefore, each frame synchronization code begins with '0 0 '. If the newly defined frame synchronization code 'FS η' is used if an existing area bit is in a connection area, it can be judged because the new frame synchronization code is different from the entity bundle 4, for example, when the combination of the frame synchronization code is For the timing, since the combination of a frame synchronization code is composed of 'FS η' and FS4, they are written in the previous real 29 and the 31st record frame (record frames #28 to #30). It is a combination of FSn-FS4 or FSn-FS2, which is obviously different from the frame synchronization code of the write set. Whether it is in a current area is based on the combination of frame synchronization codes. The seven scenarios described above are summarized below. If the appropriate restrictions are applied to the material to be written to a frame, then any other four frame synchronization codes can be, for example, if one is written after the frame synchronization code if the address of the entity always has a bit '〇〇' Headers, the codes FS 8 and FS 9 can be used without hindrance. In the special case where a physical address is not written, the group, for example, '08h' (0000 1 000) is not written in the same frame as the scrambling, and the data frame adjusted by '7PP from '0811' is used. , f] 1 7 PP adjustment code physical address is not in the above situation, easily and accurately the user on I. The existing FS4 and FS2 in the body cluster of a connected area are transformed into a solid cluster. The area is used after the exact synchronization code is used. The address of the entity, this framework synchronization can be used any four new frame synchronization code FS7-FS10 if a meta-step code followed by the meta-chain '000 1 00 20 1324765 100 100' is placed after the frame synchronization code Without having to consider RMTR constraints. The framework synchronization code is used to write one of the four new frame synchronization codes to one of the two connection frames when a known frame synchronization code FS0-FS6 is in a connection frame. Needless to say, this new framework can only be synchronized in Cases 3 and 4 of Figure 6B, as shown in the two connection frames.

If at least one selected from the new frame synchronization code 'FS η' is used to connect the frame, when the recorded material is played from a BD-ROM, the optical disk player (as shown in FIG. 9 is composed of an optical pickup) 11. A VDP system 12 and a D/A converter 13 are configured to quickly know whether the currently read frame is within the connection area or a data section (solid cluster).

In a B D - R E, the 31 recording frames respectively comprise seven different frame synchronization codes. However, the seven frame synchronization codes are not sufficient to clearly define the 31 record frames, so the frame synchronization code in the previous record frame is used to identify an existing record frame and a frame synchronization code in the existing frame. In other words, the record frame N can be identified by the continuous sync code of its own frame sync code and the frame sync code in the previous record frames N-1, N-2, and/or N-3. That is, although one or two previous synchronization codes N-1 and/or N-2 are not detected, the last detected N-3 can be used together with its synchronization code and the record frame N. Identification. For example, suppose the existing record frame is the eighth, that is, record frame #7, and its frame synchronization code is FS1 shown in the 1D chart. 21 1324765 However, the frame synchronization gema F S1 is also written in frames #1, #23 and 24, so the existing frame is identified by the previously detected frame synchronization code. The frame synchronization code FS 1 and the previously known frame synchronization 玛 FS4 ' FS1 ' and / or FS3 (in frame material, #5 and #4 respectively) can identify the existing frame as #7 One.

As mentioned above, 'because the framework of the frame synchronization code is used to identify the data 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 new frame synchronization code) is explained in detail. Figures 7A through 7C. Figures 7A through 7C show the sequence of code synchronization codes in accordance with the present invention. Fig. 7A is the first case shown in Figs. 6A and 6B. Figures 7B and 7C are the synchronization code pairs of FS7-FS7 and FS7-FS8 in the third case shown in Figure 6B, respectively. If the frame synchronization code of the FSO spear FS7 is as shown in Figure 7A

Use the framework Ν-1, Ν-2 and wide frame synchronization code before frame #0 with frame synchronization code FSO, followed by Fg7, FSO and FS2, such as case ( \\ ρκ.- a no. frame #0 Corresponds to the first address unit of a Rub. As shown in case η, _ (2), the three frames before the frame #0 in the second column are sequentially frame synchronization codes FS2, FS4 and FS4. #〇 corresponds to the intermediate address of a RUB^Xingfan. As shown in case (3), the frame of the two frames before frame #1 is >, and the V code is FSO' FS7/FS2 and FS4. Therefore, the framework #1 筮, - an address unit or - the intermediate unit of the HUB corresponds. In addition, the frame of the three frames before the * frame #2 synchronization 代马 22 1324765 sequentially FS 1, FS 0 :^〇pq 7 / ϋ c ο u and FS7 / FS2, as shown in case (4), so the frame.

Therefore, it will be difficult to detect the beginning of the connection area, and adopting this pair of FSO and FS7 will not be an appropriate solution. # In the following example, the FS7 shown in Figure 7B As an example of interpretation, as in the case of Figure 7B (1), the frame synchronization code before the frame #〇

The order is FS7/FS2 ’ FS7/FS4. And FS2/FS4. The frame #〇 is the first address unit or intermediate unit of the RUB. As shown in case (2), the framework synchronization code before the frame #1 is FSO, 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, FS0. And FS2. Frame #2 is also the first or intermediate unit of RUB. However, as shown in Figure 7B ‘B, the example of the label. According to the inventive design of the invention, the 'first connecting frame (frame #31) and the second connecting frame (#32) have the same frame synchronization code sequence in the frame frame N and the frame N-3, and when defining the connection area There may be problems. However, if the two connection frames use two F S 7, there is a newly defined frame synchronization code F S 7. In the case of detecting a • connection area, the problem caused by this condition of F S 7 - F S 7 is not more serious than the case of FS0-FS7 of Fig. 7A. Figure 7C shows the implementation of F$7 and FS8. As shown in case (1)', the frame synchronization code before frame #0 is FS8/FS2, 23 1324765

FS7 / FS4 and FS2 / FS4. Frame #〇 is the first or address unit of the RUB. As shown in case (2), the frames in front of the framework are in the same order as FSO, FS8/FS2 and FS7/FS4. Frame #1 is the first or intermediate unit. In addition, as shown in case (3), the frame synchronization before frame #2 is FS1' FS0 and FS7 / FS2. The pivot #2 is also the RUB one and the intermediate unit. As shown in Figure 7C, 'before any framework, use FS7 to synchronize code sequences with different previous frames, ie, the previous frame synchronization code order of any frame is unique, therefore, in the detection phase 7A and When one of the 7B diagrams is connected to the area, it does not cause a problem and thus the use of FS7 and FS8 is a preferred embodiment of the connection constructed in accordance with the present invention. In addition, the framework synchronization code F S 7 and F S 8 generally satisfy the RMTR constraint. Figure 8 is a flow chart of a method according to an embodiment of the present invention for playing a recording medium. If _BD_ containing the connection area constructed in accordance with the present invention is loaded (S81), the control message for playing control in BD-R〇m is first inserted into a suffix (S82)»because In this case, the management information is written into a lead-in area, which is read by a read/write head in an initial stage. Then, the main asset playback is started under the control of the control unit (S83). During playback, it is checked whether or not the frame is synchronized (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 material area (S85). If you compare the first FS8 of the RUB code in the middle of the RUB code, the code corresponding to the e-segment area as above is used for the ROM resource management. The code of the recording is required. 24 1324765 The synchronization code FS0~FS6 is recorded. Synchronized with the well-known dynasty, the defender will judge.

If it judges that the detected synchronization code is the less code (FSO~FS6) (S86) ’ written in the main data area, playback continues. However, 'if it judges that the detected synchronization code does not belong to the synchronous generation (FS0~FS6)' means that it is the newly defined synchronization code FS7 or FS8' an existing location is related to a connection area (S87), and then checks again Whether in the first connection frame or in the second connection frame (S88)» if in the first connection frame, the data after its frame synchronization code is scrambled (S 8 9). Otherwise, the existing location is related to the second connection frame, and then the data just after its frame synchronization code is scrambled (S 90).

Therefore, a disc player is composed of an optical pickup 11, a VDP system 12, and a D/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein, 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 is accurately detected. 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 learned by detecting and comparing with a newly defined frame synchronization code. . (2) Physical address As shown in Fig. 4A, the connection frame structure is written with one physical address in each recording frame of the connection area shown in Fig. 10A, and there are three cases of 25 1324765. In the first case, the AUN closest to the physical cluster #k+l after the frame is written in both connection frames. The second case is the closest to the physical cluster before the frame is written to #AUN. In the third case, the AUN of the closest physical cluster #k 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 The second connection frame.

The physical address (composed of a 4-bit address, a reserved 1-byte and a 4-bit parity, as shown in Figure 1 A) is RS (9, 5, 5) After encoding, it has error recovery capability for use by a BD-RE. The process of making an address error resilience will be detailed later.

Therefore, a disc player is composed of an optical pickup 11, a VDP system 12, and a D/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein, 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 is accurately detected. 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 one of the three recording frames of the connection area shown in Fig. 10B, and there are two cases. In the first case, the AUN closest to the physical cluster #k+l after the three connection frames t are written to the frame. The second case is written to the AUN of the closest physical cluster #k in front of the framework. The physical address (composed of a 4-bit address, a reserved 1-byte and a 4-bit parity, as shown in Figure 1 A) is RS (9, 5, 5) 26 1324765 After encoding, it has error recovery capability for use by 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, a 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 three consecutive connection frames (recording frames #k+l, #k + 2' K + 3) of the BD-ROM. In particular, if the user profile contains useful information for anti-infringement or servo-control, use CD-ROM playback to perform appropriate operations on useful information. Figure 00 is a diagram showing another embodiment of the present invention in which an address is written in a recording frame. Any of these connection frames (record frames #k+l, #k + 2) contain a 9-bit entity address, and the entity address contains a 4-bit real address. The 4-bit real address 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 before the first connection frame is a 27-bit address, and a 4-bit sequence code (0 0) indicating its order in the physical address. 0 0~1 1 1 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 (0) indicating its order in the physical address (0) 0 0 0~1 1 1 1) and 1 bit fixed value 4 0 ', as shown in Figure 10C. All the physical clusters written after it 27 27 1324765

The bit address has the same value. As mentioned before, the real address of the 4-bit tuple of the first connection frame is written to the previous physical address. For example, the real address of the 4-byte of the connection frame has the address value closest to the 1st AUN (AUN#15), and the AUN consists of 27 bits and '1: as shown in Figure 10C. . In this case, the last bit '0' of the five-bit '11110' written to the connection frame can be replaced by 1, thereby indicating that a physical address is written to a connection area and a physical cluster. In addition, the real address of the 4-byte of the second connection frame includes the address, which is written in the previous physical address. For example, the real address of the 4-byte of the first frame has the address value closest to the first (AUN#0), and the AUN is represented by the 27-bit and '00000' as shown in FIG. 10C. . In this case, the last bit '0' of the five bits '00000, which is written to the first connection, can be replaced by '1' to indicate that a physical address is written into a connection area, and The last five of the 4-bit real address of the non-entity 1 written to the first connection frame may be '00000', and the last five digits of the 4. byte written to the second connection frame may be '1' 1 1 1 0 '. In addition, an address written into a physical cluster may be written in the second connection area, and the physical cluster is one of the physical clusters before and after the connection area, as described above with reference to FIG. . (3) Scrambling The flow of the connection frame of the structure shown in Fig. 4A is the first six 110's. The first one is connected to the AUN, the frame, and the t-set. Bit Address - and or Block 28 1324765 Figure. The process of the framework of the connection framework includes scrambling 1 加入 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 32 bits of parity from the scrambler 10 and the 20-bit bit frame synchronization code preceding the user data of the added address, behind 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.

Figure 11 is a block diagram of another connection frame for the framework construction process shown in Figure 4D. The architecture of the connection framework includes scrambling 1 0' and adder 2 0 ·. The scrambler 10 0 scrambles 6 bits of user data (such as anti-infringement information) with a 9-bit physical address to make its DSV (digital sum value) trend Near zero and add a 9-bit physical address in front of the scrambled user data. Adder 2 0 self-scrambler 1 0' adds 3 2 bytes of parity to the user data of the added address. Thus, a complete 103-byte record frame is constructed which includes user data of 62 bits scrambled by a 9-bit physical address. In terms of scrambling of user data, information other than a 9-bit physical address can be used. Contrary to construction including frame synchronization code, 9-bit entity bits 29 1324765

The address, the user data of 1 1 4 bytes, and the connection framework of the 3 2 octet bits, as shown in FIG. 4A, can construct a physical address with a frame synchronization code and 9 bytes. The parity of the byte and 4-byte, and the user data of 14 6 are illustrated in Figure 4B or Figure 12A. The user data of the group can be scrambled and the 4-bit address can be used as a scrambling key. That is, in the scrambling process, a portion of the 4-bit entity bit (AddO~Add3 1) is used as an initial load value of a 16-bit recorder 101, as shown in FIG. 12B. After 0 1 in parallel loading the initial load value, each bit has a scrambling byte. Because in the embodiment of Fig. 9, the length of the user data group, - every 14 6 conversions are loaded in parallel in the conversion register 1 0 1 . After the part of the address to be loaded is loaded due to the change of the connection area, 146 scrambling bytes (S 0~S 1 4 5) are created to repute or gate "1 0 2 as user data 1 4 6 consecutive bits are "mutually exclusive". Thus, the continuous group scrambled as before is written into the connection frame. In addition to the physical address, some copies of the '10' of the frame synchronization code module can be used as a scramble key to frequency the user. In addition, one of the physical addresses written in the connection frame can be used, which is included in a physical cluster after an existing connection frame. In particular, among the 16 addresses, the closest parity connection frame contains the reserved bits of the 32-bit conversion of the real address of the 1 4 6-bit tuple. In the conversion, the conversion output is a change of 146-bit physical address. In parallel, it is disturbed by a mutual (D0-D145) 1 46 bit or bit data, before the 16 address frame or the existing connection frame 30 1324765

One address of the shelf 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 interface as shown in Figure 4C. In this case, the physical address before or after the connection frame is used as a scramble key, that is, the initial load value of a store switch. Since in this embodiment, the user resource length is 155 bytes, for every 155 conversions, the same or different real addresses are used as an initial value to load the conversion register. As shown in Fig. 13, one of the 4-bit address (Add#0~#3 1) is loaded into the 16-bit conversion register 10 of a scrambler in parallel, and the frequency is also applicable to BD. The -RE record, and then 155 8-bit scrambling bytes (SO~S1 5 4) are sequentially output during the bit conversion process. The 155 consecutive scrambling byte groups (S0~S 154) are "mutually exclusive" 1 0 2' with consecutive 155 user bytes (D 0~D 1 5 4)" Mutual or." Therefore, 155 scrambled user data (D'O~D1154) 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 portion of the bit '1 〇 ' 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 hashing or scribing unit with a value of 31 1324765 (eg, 'OOh'), as shown in FIG. 14A. A series of such fill values is called fill data. If the same data is filled in the entire user data space, a BD-ROM process can be simplified more. Incidentally, crosstalk may occur if adjacent tracks have the same bit module. Thus, as shown in another embodiment of the fill data, certain values (eg, '00h' ' '01 h,, ς l〇h', '1 lh', 'FFh', 'AAh', etc.) Write in sequence

In the data space, as shown in Figure 14B, to reduce the possibility of crosstalk. In the embodiment of the padding data record, padding data of different values are recorded in the recording frame of each connection frame deployed in a BD-ROM, which reduces the possibility of forming the same recording module between adjacent tracks. This greatly reduces the possibility of crosstalk.

The connection area of one BD-ROM forms two recording frames to ensure playback compatibility with the BD-RE. In accordance with another embodiment of the present invention, the user profile space can be populated with any of a number of distinct values, e.g., '0', '01', '11', which alternate as shown in Figure 14C. In the embodiment of the padding data recording of Fig. 4C, the user data space of a connection area has the same data, and the adjacent connection area has different padding data. In this embodiment, the possibility of forming the same recording module between adjacent tracks is small, and therefore, the possibility of occurrence of crosstalk is lowered as compared with the embodiment of Fig. 4A. The process of the BD-ROM of this embodiment is simpler than the one of Fig. 14B. 32 1324765 In addition, if a value (for example, £ Ο 0 h ') fills the entire user data space after scrambling the physical address of one of the connected regions, the crosstalk can be greatly eliminated. After the scrambling, if '〇〇h' fills the user data space, if an unscrambled '08h' is placed at the top of each user data space, then any of the above new ones can be utilized. The framework synchronizes the code without having to worry about the RMTR limits specified in the 1 7PP adjustment described above.

(5) Construction of ECC block If useful and important information is written in the user data space, it is coded by channel coding to ensure its reliability, RS (6 2, 3 0, 3 3 ) and (2 4 8,2 1 6,3 3 ) The coding system is used as a channel coding method. Those encoding systems are also set to encode user data for a set of BD-ROM physical clusters.

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, 3 0, 3 3) system first encodes the useful data for the 30-bit tuple, which creates a 32-bit parity bit. For operation, a memory sequentially stores the input data to organize a 30 0 3 0 9 data block. When a 30 0 3 0 9 data block is organized, each column (151) is scanned sequentially. The RS (62, 3 0, 3 3) encoding system produces a 32-bit tuple parity, 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 addresses can be used as a scrambling record as described before 33 1324765. 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, a padding of 145 bytes is added to the 7 1 byte containing the physical address, which is then encoded by the RS (248, 2 1 6, 3 3 ) system. This increases the parity of the 32-bit tuple. Finally, the padding data of the added 145 bytes is removed to generate a data unit of 103 bits to be written to the connection area.

The above operation is repeated for the useful data of the next 30 bytes to generate a continuous data unit of 103 bytes. After the three cells were fabricated, the three cells were followed by 4 padding bins, after which a total of 2467 bins were subjected to a 17PP adjustment. After the 17PP 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 the 30 channel bits, and the 40 channel bit repeats the bit module. The third 30 channel bit frame synchronization code and another 20 channel bit of the repeating bit module are sequentially added to the adjusted bit. The 3,864 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 octets of each connection zone 34 1324765 must inevitably constitute a single data unit. Therefore, as shown in Fig. 15C, in a 30x309 data block, a straight field of a 309 byte is written into only one column and the other 209 columns are all filled into the padding data. It means that in each of the straight-line blocks, the padding data of the 29-bit tuple is added to the useful information of the 1-byte. 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 space of the connection frame can be filled with the 114-byte useful data and the 32-bit tuple parity shown in Fig. 4A. 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 E D C (error detection code) is attached to a useful data block (S2) composed of the 2 0 48 collected bytes. The 2052 bit elements of the EDC are grouped into eighteen 1 1 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 (S 5). 9 3-bit stuffing data is added to the data unit containing the 123-bit tuple of the physical address and encoded by the RS (248, 2 1 6, 3 3) system, thereby taking the parity of the 3 2-byte The check digit is appended to the data unit. The 93 added bytes are removed to produce 155-byte frame data 35 1324765 (S6), which is then adjusted by 17PP. 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 (S 4 - S 7) is applied to the data unit of the 1 1 4 byte 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 of the 1 1 4 byte data elements, 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 used for a different address, the first connection frame uses an address written before the connection frame, and the second connection frame uses another address written after the connection frame.

As mentioned earlier, the physical address written in each connection frame can consist of a real address of 4 bytes, a reserved 1 byte, and a 4-bit 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 distinguishing individual entity addresses in the connection area. A pair of '00000/11110' or '00001/11111' can be used as the address identifier. If the former (or the latter) is used, '00000' (or '00001') is inserted into one of the physical addresses in a connection frame, and '11110' (or 36 1324765 '11111,) is inserted into another connection frame. The new framework synchronization code 'FS η' described in the above "is different from the synchronization code 'FS0~FS6 used for the nesting frame of the real plex · r", can be used in the connection, if used Different from the synchronization code of the data frame, the new framework synchronization code uses the framework synchronization code in the connection framework to write the password into the real cluster, so that the digital content recorded on the _BDR0M is free from illegal copying. .

For example, BD-RE, in the connection frame, although the recording capacity of a BD-ROM is copied to a rewritable aperture, the frame synchronization code 'FS n is not copied to A bdre is also not generated during the BD-RE recording period. The gold record that has been used for encoding cannot be acquired during the BD-RE copying of the content, so it is impossible to decode it. Therefore, the content of the BDR〇M can be exempted from illegal reconciliation. The structure of the media connection area can be ensured and the registration of the media connection area can be ensured.

Compatibility... One* can overwrite the recording media 4 ^, 磲 player or a disc player. In addition, in the case of a disc player or an optical disc drive, if necessary, the structure of the connection area of the present invention enables it to be implemented by quickly distinguishing the media disc from the recordable recording medium with a rewritable medium. Proper operation. Further, it is said that the useful information is reliably stored in a connection area by the above-mentioned recording method. Although some specific embodiments of the present invention have been disclosed, it is claimed that the invention deviating from the spirit or important characteristics of the present invention can be based on the other two: The embodiment of the invention should be considered as a description in all respects and ^ ^ 37 1324765. The scope of the invention is intended to be included within the scope of the appended claims. [Simple description of the map]
