Description

The storage means of high-capacity optical disk record format

Technical field

The present invention is the storage means of relevant a kind of optical disk record format, particularly, and relevant a kind of and CD CD compatibility, and can be applicable to record format and the storage means of high-capacity CD-ROM.

Background technology

A kind of form of service time unit, (CD-DA), video disc (Video CD or VCD), super video compact disc (Super VCD or SVCD), read-only optical disc (CD-ROM), compact disc rocordable (CD-R) and rewritable optical disc are (in the optical disk system of the form such as CD-RW) to be applied at large general music CD. The content of this kind time format comprises three parts: minute (minute), second (second) and sector (frame or block or sector), and the pattern that usually can be write as mm:ss:ff is expressed, wherein had 60 seconds in 1 minute, and divided into 75 sectors in 1 second. Pattern by mm:ss:ff be it seems, use 6 bit digital (digit: namely in the form, numeral, or figure place) binary-coded decimal system (binary-coded decimal) represents respectively above-mentioned minute, second and sector, namely binary digit is respectively expressed with 2 bit digital by every kind of unit, every units distributes the length of 4 (bit: namely, numerical digit) again, therefore altogether occupies 24.

Above-mentioned unit form can be used to indicate the address of time span or the data of data of optical disk, and for example the reproduction time of a certain music or track of video (track) is 5 minutes 16 seconds 30 sectors, can be write as 05:16:30; The original position of another music or track of video is 23:45:67 again, represents that then this track of video is that we are generally called this expression way was the MSF representation since 23 minutes 45 seconds 67 sectors.

In Q passage (channel Q), sector format Head Section and some file formats in present disk format, can use the MSF representation of the binary-coded decimal (24) of this 6 bit digital, but this MSF representation has a restriction, is exactly that the passable maximum of MSF can be limited in 99 minutes 59 seconds 74 sectors (99:59:74). Although the capacity of at present general CD format disc can not surpass the upper limit of this representation, for example the CD of general 680 Mbytes (Mega Bytes) holds at most 74 minutes music data (CD-DA) or the video data (SVCD) of 37 minutes kinds usually, that is to say that the interior MSF value of disc is at most by 74 minutes. But the development trend with current information recording medium heading high storage density it seems that the utilization of huge capacity compact discs should be within sight. If will produce the high-capacity CD-ROM that surpasses 100 minutes kinds in the future, and disc formats again with existing CD format compatible, then the MSF representation of the binary-coded decimal of known this 6 bit digital (24) is just used because representing that " hundred figure places of dividing " are inadequate.

Summary of the invention

In view of this, purpose of the present invention just provides a kind of temporal information representation of high-capacity CD-ROM data, solving the problem of hundred figure places that expression divides at least in the record format, and compatible with known CD optical disk system.

For achieving the above object, the invention provides a kind of storage means of high-capacity optical disk record format, it includes: to have the F MSF part partly that represents the M part of dividing, the S part that represents second and represent the sector in this record format of 24 bit representations; With the expansion E more than hundred figure places of dividing at least in this record format of at least 1 bit representation, and this expansion E partly separated with this MSF deposit; And merge this MSF part and this E part, and be output as the record format of an EMSF temporal information that is formed by this expansion E and the combination of this MSF part.

The present invention also provides a kind of storage means of high-capacity optical disk record format, it represents the temporal information of high-capacity CD-ROM altogether with 24 positions, it includes: the expansion E that gets hundred figure places that have in this record format of at least 1 bit representation in these 24 minute; The S part that get the M part that has representative minute in this record format of all the other bit representations in these 24, represent second and the F MSF part partly that represents the sector, and this expansion E and this MSF partly stored together; And merge this MSF part and this expansion E and be output as an EMSF temporal information that is formed by this expansion E and the combination of this MSF part.

That is to say, the storage means of high-capacity optical disk record format provided by the invention, to divide outside the MSF representation of (Minute), second (Second), sector (Frame) in original expression, the expansion E that more other increase is at least one (referred to as the E part), more than hundred figure places in order to expression minute, and it is stored among the end or specific file of Q passage (Channel Q), Head Section, original. When the system for the treatment of needs time span to be Data Position equal time information, read separately more above-mentioned MSF part and E part, and in memory, merge and be output as an EMSF temporal information, so, by means of the disclosed technology of the present invention, not only can break through the restriction of hundred figure places that original MSF representation can't represent minute, can also be oppositely and all CD format compatibles.

In addition, in other embodiments of the invention, can also utilize in original 24 MSF representations idle 2, as the position that stores the E part, so that must not look in addition under the situation of storage location, also can reach the purpose of hundred figure places of expression minute.

For above and other purpose of the present invention, special emblem and advantage can be become apparent, several preferred embodiments cited below particularly, and by reference to the accompanying drawings, be described in detail below.

The specific embodiment

Please refer to Fig. 1, it is for the data structure schematic diagram of the first embodiment of the present invention. For can be compatible with the existing disk format such as CD-DA, VCD, SVCD, CD-ROM, CD-R and CD-RW, therefore the present invention is outside existing MSF part 20, increase in addition by an E part 10, be referred to as the EMSF temporal information, and the EMSF temporal information represents at least 7 bit digital (Digit) " every minute and second sector " time with at least 25.

Above-mentioned MSF part 20 is existing record format, it represents temporal information with the binary-coded decimal (24) of 6 bit digital, wherein also include 8 M part 21,8 S part 22 and 8 F part 23, in order to minute (Minute), second (Second) and sector (Frame) that represents respectively two figure places (being binary digit); In addition, 10 of E parts are in order to the part more than hundred figure places that represent to divide, take Fig. 1 as example, suppose that E part 10 has 2, if also use binary number, then E part 10 multipotencys represent metric digital 3 (binary number 11), add aforementioned 24 MSF part 20, therefore, the EMSF temporal information maximum that can represent is 399 minutes 59 seconds 74 sectors (399:59:74).

Although above-mentioned exemplary is that E part 10 is set as 2, binary system, when the present invention was applied to optical disk system, number, system even its coded system of E part 10 employed positions all were not limited to this example. For instance, if when representing with 3, binary system and metric corresponding relation are:

Binary to decimal

001---------------------------------->1

010---------------------------------->2

100---------------------------------->4

If change octal system into above 3, then its expressed metric meaning is:

The octal system decimal system

001---------------------------------->1

010---------------------------------->8

100---------------------------------->64

In like manner, the user also can be optionally and adopt hexadecimal, and the corresponding relation between it and the decimal system is:

The hexadecimal decimal system

001---------------------------------->1

010---------------------------------->16

100---------------------------------->256

In addition, even the user can not adopt known coded system, if take 2, binary system as example, the user can change the method for its coding as required, lifts now following several example that is:

(1) binary to decimal (2) binary to decimal

00------------------------->0    00-------------------------->0

01------------------------->1    01-------------------------->2

10------------------------->2    10-------------------------->1

11------------------------->3    11-------------------------->3

(3) binary to decimal (4) binary to decimal

00------------------------->0    00-------------------------->3

01------------------------->1    01-------------------------->2

10------------------------->3    10-------------------------->1

11------------------------->2    11-------------------------->0

Because existing formatted restriction, so E part 10 can't deposit in the adjacent part of MSF part 20, must look in addition its place to store; Therefore and without prejudice but the present invention can read respectively E part 10 and MSF part 20 by the program in hardware or the software, remerges later on and obtains a complete EMSF temporal information.

As for the position of depositing E part 10, can under existing specification, do suitable selection, to keep its compatibility. The place that generally can use temporal information includes: (1) Q passage (Channel Q); (2) Head Section in the sector format; And (3) some specific file, for example on the disc of SVCD, the INFO in the SVCD catalogue, ENTRIES, TRACK and SEARCH.DAT etc., and the SCANDATA.DAT in the EXT catalogue.

See also Fig. 2, be the configuration scenario of E part 10 in Fig. 1 as example, the mode of depositing E part 10 in Q passage 30 is described. Usually the MSF temporal information 20,20 ' that has a group or two groups in the Q passage 30, if take two groups as the example explanation, the present invention utilizes two groups of MSF temporal informations 20,20 ', if take two groups as the example explanation, the present invention is the null value district (referred to as the ZERO district) 31 (having 8) that utilizes two groups of MSF temporal informations 20,20 ' centre, as depositing E part 10 parts. Because the E part 10 among Fig. 1 has 2, therefore then need 4 altogether if will represent secondary MSF temporal information 20,20 ' E part 10,10 ', for example shown in Fig. 2, can choose b6b7 (the 7th and the 8th position) and deposit first group E part 10, and deposit second group E part 10 ' with b4b5 (the 5th and the 6th position). May use above-mentioned method, E part 10 is stored in the CD specification in the ZERO district 31 of Q passage 30, include CD-DA, VCD, SVCD, CD-ROM, CD-R and CD-RW etc.; But it should be noted: represented just exemplary among Fig. 2, can determine by situation during practical application to use in 8 ZERO districts 31 which and how to use.

Please refer to Fig. 3, the configuration scenario of E part 10 illustrates the mode of depositing E part 10 in the Head Section 35 in sector format as example in Fig. 1. Show among the figure that Head Section 35 has 4 bytes (Byte) altogether, deposit 3 bytes of MSF part 20 except existing that other has a pattern byte 36 (Mode Byte). Therefore we can be stored in E part 10 among the spare bit of pattern byte 36, for example b2b3 (the 3rd and the 4th position). May use said method, E part 10 is stored in the CD specification of the pattern byte 36 of Head Section 35, include VCD, SVCD, CD-ROM, CD-R and CD-RW etc. It should be noted equally: represented also typical case just among Fig. 3 can according to circumstances determine to use which position in the spare bit during practical application and how to use.

As for utilizing file to store the mode of E part 10, be because of different file formats, the number of the MSF part 20 that it records may be different, and different CD contents, and the number of the MSF part 20 that is recorded in its file also may be different. In addition, original file format space some will be not enough to add newly-increased E part 10. Based on above-mentioned these reasons, therefore the present invention selects the MSF part 20 corresponding E parts 10 in each file are deposited in the new file, and this new file placed relevant catalogue, or according to circumstances E part 10 that it is corresponding to deposit in the end of original good. E part 10 may be stored in the CD specification of file, include VCD and SVCD etc.

If take the specification of SVCD as example, can use the file relevant with MSF part 20 has INFO, ENTRIES, TRACK and SEARCH.DAT etc. in the SVCD catalogue and the SCANDATA.DAT in the EXT catalogue. Therefore, the present invention can be chosen in and set up two files in the SVCD catalogue, and one of them file name is EMSF1, is used for depositing each MSF part 20 corresponding E part 10 of file such as INFO, ENTRIES and TRACK. Another file name is EMSF2, is used for depositing each MSF part 20 corresponding E part 10 of SEARCH.DAT. In addition, in the EXT catalogue, set up in addition the file that a name is called EMSF3, be used for depositing each MSF part 20 corresponding E part 10 of SCANDATA.DAT. But similarly, above-mentioned expression mode is a typical case also, can according to circumstances determine the number of file and the title of file during practical application.

The file structure of the EMSF1 file among above-mentioned can be with reference to as shown in table 1. In the specification of SVCD, INFO file only " broadcast multiple segments voice separately project initial address " place need to use MSF part 20. And the ENTRIES file is up to entrance 1 to entrance 500, therefore needs at most 500 entry addresses to use the MSF representation. At last, the TRACK file then has N track reproduction time can use the MSF representation, and wherein N represents the actual track number. Although the length of above-mentioned each E part still can be assumed to be 2, for convenience's sake, then all deposits it with 8 (1 byte) in the table 1.

Table 3

Understand how to store E part 10 with and form after, please refer to Fig. 4, it for file reading of the present invention to obtain the flow chart of whole EMSF information. At first, by system identification and the standard version number of CD, just can know general CD or high-capacity CD-ROM (step 401), if judged result is high-capacity CD-ROM, then continue this flow process, get final product with known method processing otherwise jump out this flow process. Above-mentioned be judged as certainly after, set first and deposit the memory area (step 402) of merging into the EMSF temporal information. Then read the MSF part 20 among the optical file, and be stored in the correspondence position (step 403) among the above-mentioned memory. If its time information has E part 10 (step 404), then read the E part 10 in the CD respective file, simultaneously it is stored in the correspondence position (step 405) among the above-mentioned memory, remerge the complete EMSF temporal information (step 407) of output, otherwise just the E part 10 among the memory is set as 0 (step 406), again the EMSF temporal information (step 407) of output merging.

Except above-mentioned E part 10 and MSF part 20 are separated the mode that stores, can also utilize the idle position in the original MSF representation, as storing E part 10 parts. Please refer to Fig. 5, it is the data structure schematic diagram of second embodiment of the invention. Because S part 22 and F part 23 in the known MSF representation, its maximum respectively is 59 (seconds) and 74 (sectors), it seems with the situation of using separately 2 bit digital (8) binary-coded decimal to represent, S part 22 all is " 0 " with last position of F part 23 forever, namely all in idle state, as follows:

S part F part

The decimal system 59 74

Binary Zero 101 1,001 0,111 0100

Thus, the present invention can divide into 2 E part 10 among Fig. 1 the first expansion 11 of 1 (referred to as E₁Part) with the second expansion 12 of 1 (referred to as E₂Part), and deposits in respectively among the above-mentioned idle position, take out respectively again merging when need waiting. Perhaps, and then shown in Fig. 6 A and Fig. 6 B, S part 22 and F part 23 all are reduced to 7 positions (still being 2 bit digital), and transfer its position, so that M part 21. S part 22 is still together adjacent with F part 23, and allows 24 2 of vacating front or back that originally are used for storage MSF part 20 come, and deposits E part 10 parts to be used as. Because in the 2. 3rd and the 4th embodiment, all be to utilize the idle position of existing MSF part 20 to deposit E part 10, the storage location of therefore certain E part 10 is all identical with aforesaid MSF part 20.

Please refer to Fig. 7 A and Fig. 7 B, the present invention also can under the framework of Fig. 5, only adopt E wherein₁Part 11 or E₂Part 12 that is to say and also can only use 1 position to store hundred figure places of dividing. Wherein, the user can be shown in Fig. 7 A, only selects the idle position (E namely with S part 22₁Part 11), be about to E₂Part 12 is idle, or shown in Fig. 7 B, only selects the idle position (E namely with F part 23₂Part 12), be about to E₁Part 11 is idle, no matter is above-mentioned which kind of selection mode, and it can represent that the maximum of temporal information all is 199 minutes 59 seconds 74 sectors.

The present invention utilizes additional storage one E part, the mode that partly merges with original MSF again, not only can be compatible with disk formats such as known CD-DA, VCD, SVCD, CD-ROM, CD-R and CD-RW, and can break through the restriction of existing CD disc formats, be applied to surpass 100 minutes high-capacity CD-ROM, to cooperate the trend of high density compact disc development.
