Embodiment

Below, will use accompanying drawing to describe an example of the video server that is used for television broadcasting according to an embodiment of the invention in detail.

(video server according to an embodiment of the invention)

At first, will use Fig. 1 to describe the example of the whole configuration of video server according to an embodiment of the invention.This video server comprises with lower unit.

1. many (for example, 5) SDI input/output end ports 1 are used for input and output SDI standard serial digital signal

2. group memory (bank memory) 2 is used for blotter AV data

3. group Memory Controller 3 is used for reading the AV data or writing the AV data to group memory 2 from group memory 2

4. serve as jumbo flash memory 4 of having of main storage means and CD drive 5

5.FPGA6, comprise the low performance processor that is used to control flash memory 4 and CD drive 5

6.CPU 7, be used to control SDI input/output end port 1 and group Memory Controller 3

7.CPU 8, be used for storage administration flash memory 4 and CD drive 5 the AV data file system and as the more high level procedural documentor of this document system, and be used to control the whole video server

8.FPGA 9, comprise such low performance processor, this processor be used for to CPU 8 send use that the RS-422 agreements receive from the outside, at the recoding/reproduction order of each SDI input/output end port 1, and to be used for the state exchange from CPU 8 be the RS-422 agreement, so that it is turned back to the outside

9. the edit operation panel 10, are used for the AV data that are recorded in flash memory 4 and CD drive 5 are carried out shearing editor etc.

When FPGA 9 receives record order about any one SDI input/output end port 1, the SDI standard serial digital signal that is input to SDI input/output end port 1 is in the AV data that are converted into parallel form under the control of CPU 8 and CPU 7, in the 1a of I/O processing section, by codec (codec) 1b with long GOP form encode (compression), be sent to group Memory Controller 3, and be written to group memory 2 by frame by frame by group Memory Controller 3.

Then, when being written into from the AV data of the specified quantitative of SDI input/output end port 1 each time, these AV data and are recorded in flash memory 4 or the CD drive 5 (depending on the appointment of record order) as file via FPGA 6 under the control of CPU 8 and CPU 7, be read out the memory 2 from group by group Memory Controller 3.

In addition, when FPGA 9 receives reproduction order about any one SDI input/output end port 1, the AV data are read out from flash memory 4 or CD drive 5 (depending on the appointment of reproducing order) under the control of CPU 8 and CPU 7, and video data is written to group memory 2 via FPGA 6 by group Memory Controller 3.

The AV data are read from group memory 2 by frame by frame by group Memory Controller 3, and are sent to SDI input/output end port 1.These AV data, and are converted into SDI standard serial digital signal and export waiting with long GOP form decoded (expansion) by the codec 1b in the SDI input/output end port 1 in the 1a of I/O processing section.

(the paper cut editing and processing in the main storage means)

Next, the example of the paper cut editing and processing in the main storage means of this video server will be described in.Edit operation panel 10 allows to carry out under the situation of the proxy data (proxy-data) (video data with low resolution that is used for edit operation) of the AV data of reference record in flash memory 4 or CD drive 5, on the GUI screen shears edit operation, and described proxy data is output to monitor (display etc. that perhaps has the edit operation panel 10 that is connected with SDI input/output end port 1 of HDMI (high-definition media interface)) from any one SDI input/output end port 1.Shear in the edit operation at this, for shearing editing files A and B to be edited, can carry out following operation: the tie point of going into (IN) point, file A and B of specified file A (can specify in GOP in the middle of frame) and file B go out (OUT) point, as shown in Figure 3A.In addition, can carry out indication deletion file A to be edited or the operation of B on demand.

When the information of this shearing edit operation on edit operation panel 10 was sent to CPU 8, the shearing editing and processing that CPU 8 carries out as shown in Figure 2 was as the processing of being carried out by above-mentioned file system, file manager etc.

In this is handled, at first, in two files to be edited (also being designated as file A and file B here), the frame of the GOP boundary before the adjacent tie point in file A is determined the point as OUT, and the frame that is right after the GOP boundary after the tie point in file B is determined as IN point (step S1).Fig. 3 B shows the treatment state of this step S1, and is corresponding with the above operation of describing with reference to figure 3A.

After step S1, the frame from OUT point (the OUT point of determining among step S1) to tie point among the file A and the frame of the point from tie point to IN among the file B (the IN point of determining among step S1) are read from main storage means (flash memory 4 of log file A and B or CD drive 5), and are sent to group Memory Controller 3 (Fig. 1) (step S2) via FPGA 6.

Then, send order to CPU 7 (Fig. 1) and create the bridge joint file with request, this bridge joint file is the file (step S3) that OUT point among the threaded file A and the IN among the file B are ordered.

After receiving described order, CPU 7 is by encoding and create described bridge joint file being sent to the frame of point from the tie point to IN group frame from the OUT point to tie point Memory Controller 3, among the file A and the file B, thereby can not destroy the VBV buffer (with the corresponding virtual bumper of the input buffer of decoder-side device) that meets mpeg standard.

This bridge joint file is created according to following frame, the number of described frame is equal to or less than the frame number of a GOP in each of file A and B, thus this bridge joint file have with by the data of shearing the data volume edit operation appointment, or the file B the irrelevant relatively small amount of from the tie point to the OUT data volume of the frame of point from the IN point to the frame of tie point among the file A.CPU 7 sends to main storage means via FPGA 6 from group Memory Controller 3 with the bridge joint file of being created.

After step S3, when the bridge joint file was sent to main storage means, CPU 8 was with bridge joint file logging (step S4) in the clear area of main storage means.With Fig. 3 A and Fig. 3 B accordingly, Fig. 3 C shows the state of this processing of step S4.

After step S4, edited result file (being designated as file C) is created the assignment information that becomes to have as filesystem information (being called AD: distribute descriptor), record position and whole bridge joint file the record position (step S5) in main storage means of part (being designated as B ') main storage means of ordering to OUT from the IN point among the record position of the part (being designated as A ') of ordering to OUT from the IN point among this assignment information indication file A main storage means, the file B.

Fig. 4 is to show the state of this processing among the step S5 with Fig. 3 A, Fig. 3 B and the corresponding mode of Fig. 3 C.Here, when log file A, file B and bridge joint file (the bridge joint file writes down in step S4), generated as filesystem information respectively about the AD of file A, file B and bridge joint file.

After step S5, (cluster) management information of trooping is generated, be used to manage and the AD of AD, the file B of file A and corresponding the trooping of AD of bridge joint file, as respectively by the zone of file A, file B and bridge joint file references, and be used to manage corresponding the trooping of AD with edited result file C, by the zone of edited result file C reference, each is trooped by file system management, unit record zone in main storage means as also.Then, this cluster management information is stored in the memory of CPU 8 (step S6).

Particularly, when file A, file B and bridge joint file are recorded, with regard to regard to corresponding the trooping of AD of the AD of AD, the file B of file A and bridge joint file, because these are trooped respectively by file A, file B and bridge joint file references, so the number of times of reference is set to " 1 ", and in step S6, with regard to during these are trooped with regard to corresponding the trooping of AD of edited result file C, because these are trooped also by the reference of edited result file institute, thus the number of times of reference upwards counting be " 2 ".Then, this information about reference number of times is used as cluster management information.

Fig. 5 is to show the state of this processing of step S6 with Fig. 3 A, Fig. 3 B, Fig. 3 C and the corresponding mode of Fig. 4.In troop with the AD of file A is corresponding (cluster number 1 to 4), troop (cluster number 2 and 3) is also corresponding with the AD of edited result file C, and its reference number of times becomes " 2 ", and the reference number of times of other troop (cluster number 1 and 4) still is " 1 ".In addition, in troop with the AD of file B is corresponding (cluster number 5 to 9), troop (cluster number 6 and 7) also corresponding with the AD of edited result file C, and its reference number of times becomes " 2 ", and the reference number of times of other troop (cluster number 5,8 and 9) still is " 1 ".Simultaneously, troop with the AD of bridge joint file is corresponding (cluster number 10) is also corresponding to the AD of edited result file C, and its reference number of times becomes " 2 ".

As shown in Figure 2, after step S6, generate the address information of each frame that comprises edited result file C and the index information (being called the picture pointer) (step S7) of size information mutually independently with the picture pointer (picturepointer) of file A and B.

Because the frame sign of the AV data of encoding with long GOP form is not constant but variable, so this picture pointer is a necessary information for the fast access to arbitrary frame.The picture pointer of file A or B is generated when writing down them.

Fig. 6 is the diagrammatic sketch that is illustrated among the step S7 state of the picture pointer that generates edited result file C, compares with the state of the picture pointer of spanned file A.Because the picture pointer begins frame is addressed from the top of file, thus in the picture pointer of file A, from the address of the frame of IN point beginning be n, n+1, n+2 ... (n is the integer more than or equal to 1).Simultaneously, from the edited result file C of the IN point of file A beginning, the address of the frame that begins from identical IN point is 0,1,2 ...The size information of the frame of ordering from the IN point to OUT the frame of ordering to OUT from the IN point among the file A, the frame of bridge joint file and the file B is identical.

As shown in Figure 2, after step S7, bridge joint file deleted (step S8).Here, it should be noted that, be stored in file system among the CPU 8 by subtracting 1, come on file system the execute file deletion to handle, and AV data itself do not deleted from main storage means with the corresponding reference number of times of trooping of AD (with reference to figure 5) of file to be deleted.Therefore, the deletion of the bridge joint file among the step S8 also only be by will have with the reference number of times of troop (the having trooping of cluster number 10 among Fig. 5) of the corresponding cluster number of AD of bridge joint file downwards counting carry out for " 1 ".After completing steps S8, shear editing and processing and stop.

By above-mentioned shearing editing and processing, when when shearing editor with the file of the AV data of long GOP form coding, described video server is only newly created has small data quantity, be used for to treat the interconnective bridge joint file of editing files, and with this bridge joint file logging in the main storage means (flash memory 4 or CD drive 5), and in main storage means, do not duplicate (settling again) file described to be edited, and use the information of the record position of the part that will be used to edit (being respectively each frame of ordering of file A and B) that indicates file A and file B to create the edited result file from the IN point to OUT.

Therefore, can be under the situation of the mass data of not duplicating file to be edited to editing with the AV data of long GOP form coding, and thereby the consumption of main storage means capacity can be remained on minimum, and reduced the needed time of editor.

In addition, treat trooping of editing files institute reference and trooping of edited result file institute's reference by managing respectively, during these are trooped each is the unit record zone in the main storage means, then can dispose indistinguishably, independently and treat editing files and edited result file, thereby even can delete and treat editing files.

In addition, because record position is to generate independently mutually with the picture pointer for the treatment of editing files by the address information of each frame that the edited result file is indicated with size information (picture pointer), even so after treating by deletion that editing files has been deleted the picture pointer for the treatment of editing files on the file system, also can reproduce the arbitrary frame of this edited result file by this edited result file of picture pointer fast access based on the edited result file.

Fig. 7 is with the corresponding mode of Fig. 5 the diagrammatic sketch of deleting the state for the treatment of editing files A based on the operation on edit operation panel 10 to be shown.In troop with the AD of file A is corresponding (cluster number 1 to 4), also be " 1 " by counting downwards, and the reference number of times of other troop (cluster number 1 and 4) is " 0 " by counting downwards with the reference number of times of corresponding the trooping of AD (cluster number 2 and 3) of edited result file C.Reference number of times becomes the open clear area for the AV data that allow to write down therein new file of the trooping of " 0 " ( cluster number 1 and 4).With the reference number of times of corresponding the trooping of AD (cluster number 2 and 3) of edited result file C be " 1 ", and do not allow to write down therein the AV data of new file, to keep the content of original record.

(treating the recording processing of the filesystem information of editing files and bridge joint file)

Next, with two examples describing about the recording processing of the filesystem information for the treatment of editing files and bridge joint file in the video server shown in Figure 1 (AD shown in Figure 4, that treat editing files A and B and bridge joint file).

[example 1]

At first, first example will be described.In the time will treating that editing files or bridge joint file logging are in flash memory 4, the piece of the 8M byte that CPU 8 (Fig. 1) will be made up of 64 pages (every page of 128k byte) is considered as one and troops, that is, and and the unit record zone.Then, as shown in Figure 8, to as the FS page or leaf in the zone of filesystem information (AD) with as the PP page or leaf in the zone of above-mentioned picture pointer (address information of each frame and size information) one page in the allocation block respectively.

Because it is all very little that the AD of the AV data in piece and the data volume separately of picture pointer are compared with the size of one page, thus can be in a FS page or leaf and PP page or leaf the AD and the picture pointer of AV data of a plurality of of records.

Then, when the AV data of editing files and bridge joint file treated in record, as the processing of being carried out by above-mentioned file system, documentor etc., CPU 8 carried out the recording processing of AV data and filesystem information, as shown in Figure 9.

In this is handled, at first before being recorded in the AV data in the current block, judge in the piece that has crucial FS (will describe after a while), whether to have recorded AV data (step S21).

If whether the answer among the step S21, then the AV data be recorded in the current block except FS page or leaf and PP page or leaf the page or leaf in, the picture pointer that has recorded at present the AV data in the piece (comprising current block) of AV data (here, at the PP page or leaf since write down the 128k byte the picture pointer and under the saturated situation, be the picture pointer of the AV data in the piece of back) by cumulative record in the PP page or leaf, and the AD that has recorded the AD of the AV data in the piece (comprising current block) of AV data and saturated PP page or leaf at present is by cumulative record (step S22) in the FS page or leaf.

Then, judge FS page or leaf whether saturated (whether having write down the AD of 128k byte) (step S23) in the current block.

If the answer among the step S23 is that then in the memory of CPU 8, the content of the current FS address of the FS page or leaf that stored expression is nearest is not updated to the address (step S25) of the FS page or leaf in the current block.Simultaneously, if the answer of step S23 is for being, then the address of the FS page or leaf in the current block is stored in the memory of CPU 8 as crucial FS address (step S24), handles then and advances to step S25.

Then, the record of whether having finished whole AV data is judged (step S26).If the answer among the step S26 is then handled and moved to the next piece (step S27) that is used to write down for not, turn back to step S21 then.

If the answer among the step S21 is for being, then the AV data be recorded in the current block except FS page or leaf and PP page or leaf the page or leaf in, the picture pointer that has recorded at present the AV data in the piece (comprising current block) of AV data (here, when having saturated PP page or leaf, be the picture pointer of the AV data in the subsequent block) by cumulative record in the PP page or leaf, and the AD of the AD of the AV data in the piece after having the piece of crucial FS (comprising current block) and saturated PP page or leaf is by cumulative record (step S28) in the FS page or leaf.Then, processing advances to step S23.

If the answer among the step S26 is for being, then the AD of the PP page or leaf in the current block further is recorded in the FS page or leaf that has become current FS (step S29), and handles and stop.

Figure 10 is that example illustrates the diagrammatic sketch that writes down the state of AV data and filesystem information by the processing of Fig. 9.In first piece b1, the AV data have been write down, and in the PP page or leaf, write down the picture pointer of the AV data among the piece b1, and in the FS page or leaf, stored the AD (leading address and the size of each key element (video and each voice-grade channel 1 to 4)) (the step S22 among Fig. 9) of the AV data among the piece b1.

In next piece b2, write down the AV data, and in the PP page or leaf, write down the picture pointer of the AV data among piece b1 and the b2, and in the FS page or leaf, write down the AD (the step S22 among Fig. 9) of the AV data among piece b1 and the b2.In next piece b3, write down the AV data, and in the PP page or leaf, write down the picture pointer of the AV data of piece b1 in the b3, and in the FS page or leaf, stored the AD (the step S22 among Fig. 9) of the AV data of piece b1 in the b3.

In piece b4 subsequently, write down the AV data, and in the PP page or leaf, write down the picture pointer of the AV data of piece b1 in the b4.In addition, because the PP page or leaf has been saturated, so the AD of the AV data of piece b1 in the b4 and the AD of the PP page or leaf among the piece b4 are stored in (the step S22 among Fig. 9) in the FS page or leaf.

In next piece b5, the AV data have been write down, and in the PP page or leaf, write down the picture pointer of the AV data among the piece b5, and the AD of the AV data of piece b1 in the b5 and the AD (the step S22 among Fig. 9) (after piece b4, some arrows that are used to indicate the corresponding relation between PP page or leaf or FS page or leaf and the piece only being shown) of the PP page or leaf among the piece b4 in the FS page or leaf, have been stored.

In next piece b6, the AV data have been write down, and in the PP page or leaf, write down the picture pointer of the AV data among piece b5 and the b6, and in the FS page or leaf AD of the AV data of memory block b1 in the b6 and the AD (the step S22 among Fig. 9) of the PP page or leaf among the piece b4, thereby the saturated crucial FS (the step S24 among Fig. 9) that becomes of FS page or leaf as a result.

In next piece b7, write down the AV data, and in the PP page or leaf, write down the picture pointer of the AV data of piece b5 in the b7, and in the FS page or leaf AD of the AV data among the record block b7 (the step S28 among Fig. 9).

In next piece b8, write down the AV data, and in the PP page or leaf, write down the picture pointer of the AV data of piece b5 in the b8.In addition, because the PP page or leaf is saturated, so the AD of the AD of the AV data among piece b7 and the b8 and the PP page or leaf among the piece b8 is stored in (the step S28 among Fig. 9) in the FS page or leaf.

In next piece b9, write down the AV data, and in the PP page or leaf, write down the picture pointer of the AV data among the piece b9, and in the FS page or leaf AD of the AV data of memory block b7 in the b9 and the AD (the step S28 among Fig. 9) of the PP page or leaf among the piece b8.Then, owing in piece b9, finished the record of AV data,, the AD of the PP page or leaf among the piece b9 become in the FS page or leaf current FS, among the piece b9 (the step S29 among Fig. 9) so also being recorded in.

By this recording processing, owing to not visiting flash memory 4 just to log file system information (AD) and picture pointer, and in record AV data, at same middle log file system information and picture pointer, so can write down by frequent updating and have the in a small amount filesystem information and the picture pointer of data to be updated, keep the access performance (bit rates of the AV data during the recoding/reproduction) of flash memory 4 simultaneously.

In addition, the AD of the AD of the AV data in all pieces and PP page or leaf be recorded among the crucial FS and current FS in.For example, in the example of Figure 10, the AD of the AV data of piece b1 in the b6 and the AD of the PP page or leaf among the piece b4 are (promptly, assignment information about the picture pointer of the AV data of piece b1 in the b4) is recorded among the crucial FS, and the AD of the AD of the AV data of piece b7 in the b9 and the PP page or leaf among piece b8 and the b9 assignment information of the picture pointer of the AV data of piece b5 in the b9 (that is, about) is recorded among the current FS.

Therefore,, just can obtain the AD of the whole AV data that write down, and can obtain to have write down the AD of PP page or leaf of the picture pointer of the whole AV data that write down by only reading crucial FS page or leaf and current FS page or leaf.Especially, can not visit flash memory 4, so can from a plurality of these distributed pages or leaves, obtain AD and picture pointer immediately owing to just do not need to search.Thereby, can manage filesystem information and the picture pointer for the treatment of editing files and bridge joint file, keep the access performance of flash memory 4 simultaneously.

[example 2]

Next, description is treated second example of recording processing of the filesystem information of editing files and bridge joint file.In the time will treating that editing files and bridge joint file logging are in flash memory 4, CPU 8 (Fig. 1) also is considered as piece to troop, and trooping is the unit of posting field.Then, as shown in figure 11, to the FS page or leaf regional with as a page or leaf in the PP page or leaf difference allocation block in picture pointer (address of each frame and size information) zone as filesystem information (AD).(so far identical) with Fig. 8

In addition, in this FS page or leaf, for example the zone of 1k byte is reserved as the zone of record as the address of the saturated FS page or leaf of search index, and the zone of all the other 127k bytes is reserved as the zone of AD.Here, the zone of supposing to be used for search index is that the 1k byte only is an example, and can be identified for the byte number in the zone of search index according to the data volume of AV data, thereby can write down the address of all saturated FS pages or leaves, the number that reason is saturated FS page or leaf is along with the increase of the data volume of AV data increases.

Then, when the AV data of editing files and bridge joint file treated in record, CPU 8 carry out as shown in figure 12 the AV data and the recording processing of filesystem information, as the processing of using above-mentioned file system, documentor etc.

In this is handled, at first before being recorded in the AV data in the current block, judge in the saturated piece of FS page or leaf whether recorded AV data (step S31).

If the answer among the step S31 is for denying, then the AV data be recorded in the current block except FS page or leaf and PP page or leaf the page or leaf in, the picture pointer that has recorded at present the AV data in the piece (comprising current block) of AV data is (when existing saturated PP page or leaf, be the picture pointer of the AV data in the subsequent block) by cumulative record in the PP page or leaf, and the AD that has recorded at present the AD of the AV data in the piece (comprising current block) of AV data and saturated PP page or leaf by cumulative record in the AD zone of FS page or leaf (step S32).

Then, in the memory of CPU 8, the content of the current FS address of the FS page or leaf that the indication of being stored is nearest is updated to the address (step S33) of the FS page or leaf in the current block.

Then, the record of whether having finished the AV data is judged (step S34).If the answer among the step S34 is then handled and moved to next piece (step S35) to be recorded for not, turn back to step S31 then.

If the answer among the step S31 is for being, then the AV data be recorded in the current block except FS page or leaf and PP page or leaf the page or leaf in, the picture pointer (when having saturated PP page or leaf, be the picture pointer of the AV data in the piece) subsequently that has recorded at present the AV data in the piece (comprising current block) of AV data by cumulative record in the PP page or leaf.In addition, the address of all saturated FS pages or leaves is recorded in the search index zone of FS page or leaf, and the AD of the AD of the AV data in the piece after the piece that has saturated FS page or leaf (comprising current block) and saturated PP page or leaf by cumulative record in the AD zone of FS page or leaf (step S36).Then, processing advances to step S33.

If the answer among the step S34 is for being that then the AD of the PP page or leaf of current block further is recorded in (step S37), termination then in the FS page or leaf that has become current FS.

Figure 13 illustrates the diagrammatic sketch that writes down the state of AV data and filesystem information by processing shown in Figure 12.The address of all saturated FS pages or leaves (being designated as the FS address) all is recorded in the search index zone among the current FS.In addition, identical with the FS page or leaf of piece b9 shown in Figure 10, the AD of the PP page or leaf of the AV data in all pieces after the piece that has saturated FS page or leaf and the AD of saturated PP page or leaf and current block is recorded in the AD zone of current FS.

By this recording processing, owing to not visiting flash memory 4 just to log file system information (AD) and picture pointer, and in record AV data, with filesystem information and picture pointer record in identical piece, upgrade filesystem information and picture pointer frequent and that have a small amount of data to be updated so can write down, keep the access performance (bit rates of the AV data during the recoding/reproduction) of flash memory 4 simultaneously.(so far, identical) with the recording processing of [example 1].

In addition, as illustrated in Figure 13, the address of all saturated FS pages or leaves all is recorded in the search index zone of current FS.Therefore, by reading the page or leaf of current FS, and read saturated FS page or leaf subsequently, the address of this saturated FS page or leaf is recorded in its search index zone, then can obtain the AD of the whole AV data that write down, and can obtain to have write down the AD of PP page or leaf of the picture pointer of the whole AV data that write down.

Promptly, in the recording processing of [example 2], only must store the address of current FS, and in the recording processing of [example 1], the number of the page or leaf of the address of storage FS page or leaf is not fixed, reason has been to store crucial FS address and current FS address (increase of the data volume of AV data has increased the number of saturated FS page or leaf, and the result causes the increase of crucial FS).Therefore, can more easily manage filesystem information and the picture pointer for the treatment of editing files and bridge joint file, keep the access performance of flash memory 4 simultaneously.

In [example 1] and [example 2], described and to have treated editing files and the situation of bridge joint file logging in flash memory 4.But, be not limited to this situation.When treating that editing files and bridge joint file are recorded in the CD drive 5 (Fig. 1), the part of each record cell (trooping) of CD each zone that is used for filesystem information and picture pointer can be distributed to, and the identical processing shown in Fig. 9 or 12 can be carried out.In addition, be provided with register system hard disk drive, such as video server that is used for main storage means, the part of each record cell (trooping) of hard disk drive each zone that is used for filesystem information and picture pointer can be distributed to, and the same treatment shown in Fig. 9 or 12 can be carried out.

Here, different with flash memory, CD drive or hard disk drive are to have the equipment search problem, and when filesystem information or the picture pointer processing distributed earth by Fig. 9 or 12 is recorded, will be a problem very long readout time.So, when the processing in Fig. 9 or 12 is applied to CD drive or hard disk drive, the filesystem information and the picture pointer that can will be recorded in when system start-up in CD drive or the hard disk drive are loaded on the equipment that be not problem search time as Backup Data, for example, memory among the CPU 8, thereby the read operation of using this equipment to come execute file system information and picture pointer, and thereby can improve system reliability.

(recording processing of the filesystem information of edited result file)

Next, the example of the recording processing of filesystem information in the video server shown in Figure 1, the edited result file (AD of edited result file C shown in Figure 4) will be described in.

In shearing editing and processing shown in Figure 2, edited result file C is created the following A D (assignment information) that becomes to have as filesystem information, and this AD indicates the record position of ordering from the IN point to OUT for the treatment of editing files (file A and B) and the record position (step S5) of whole bridge joint file.But, in this shears editing and processing, do not mention: be that AD at edited result file C (with reference to figure 4) generates new AD, still have no to change ground (not generating new AD) and utilize the AD that treats editing files and bridge joint file that has generated.

Here, consideration such a case is arranged, wherein, at after treating that editing files and bridge joint file are carried out the recording processing of AV data and filesystem information by the mode shown in Fig. 8 to 10 or Figure 11 to 13, the AD that treats editing files and bridge joint file had no to be used for with changing the AD of edited result file C.

Figure 14 illustrates the diagrammatic sketch of situation that AD with file A has no to be used for the AD of edited result file C with changing, suppose AV data of ordering to OUT from the IN point in the file A shown in Fig. 3 B be recorded among the piece b4 that has saturated FS page or leaf as Figure 10 or flash memory 4 shown in Figure 13 a plurality of and two piece b5 subsequently and b6 in (having omitted the PP page or leaf among the figure of Figure 14).In this case, the AD that is recorded in the file A in the FS page or leaf of piece b4 in the b6 is used as the AD of edited result file C.

But, though the piece b5 of the part of the edited result in the file A (the scope of order to OUT from the IN point) and the AD of the AV data among the b6 are recorded in the FS page or leaf among piece b5 and the b6, be recorded among the piece b4 as the AD both of the AD of the AV data among the edited result piece b4 partly and the AV data that are not edited result piece b1 partly in the b3.Therefore, there is not the filesystem information of only representing as the record position of the AV data among the piece b4 of edited result part.

For fear of this situation, the filesystem information (AD) of preferably newly-generated whole edited result file C.Here, because edited result file C does not duplicate AV data self, but have no to utilize the AV data treated in editing files and the bridge joint file (as illustrated in Figure 5 with changing, utilize reference number of times to manage the AV data), so its filesystem information can't come record by the processing about treating editing files and bridge joint file shown in Fig. 8 to 10 or Figure 11 to 13.

So, a kind of like this method will be described, this method is used for the filesystem information of newly-generated edited result file C and is used for this filesystem information of record edited result file C in record bridge joint file.Figure 15 is the flow chart that the example of the recording processing of being carried out by CPU 8 that is used for this purpose is shown, and wherein, the part of the recording processing among Figure 12 is changed, and in this external shearing editing and processing shown in Figure 2, step S5 and S7 and step S4 merge.

In this is handled, at first, before being recorded in the AV data in the current block, judge whether the AV data have been recorded in (step S41) in the piece that has saturated FS page or leaf.

If the answer among the step S41 judges then for not whether current block is last piece (step S42) that will write down the AV data of bridge joint file.

If the answer among the step S42 is for denying, then in current block, described AV data be recorded in except FS page or leaf and PP page or leaf (Figure 11) the page or leaf in, the picture pointer that has recorded the AV data in the piece (comprising current block) of AV data so far (here, under the situation of the saturated PP page or leaf that has the picture pointer that has wherein write down the 128k byte, be the picture pointer of the AV data in the subsequent block) by cumulative record in the PP page or leaf, and the AD that has recorded the AD of the AV data in the piece (comprising current block) of AV data and saturated PP page or leaf so far by cumulative record in the AD zone of FS page or leaf (Figure 11) (step S43).

Then, in the memory of CPU 8, the content about the current FS address of bridge joint file of being stored is updated to the address (step S44) of the FS page or leaf in the current block, and handles and move to the next piece (step S45) that is used to write down, and turns back to step S41 then.

If the answer among the step S42 then generates the picture pointer (corresponding to the step S7 among Fig. 2) of edited result file C for being, in addition, the filesystem information (AD) (step S46) of newly-generated as described above whole edited result file C.

Then, in current block, the AV data be recorded in except FS page or leaf and PP page or leaf the page or leaf in, the picture pointer that has recorded the AV data in the piece (comprising current block) of AV data so far (here, when having the saturated PP page or leaf of the picture pointer wherein write down the 128k byte, be the picture pointer of the AV data in the subsequent block) by cumulative record in the PP page or leaf.In addition, the AD that has recorded the AD of the AV data in the piece (comprising current block) of AV data and saturated PP page or leaf so far is also by cumulative record, and the AD of the PP page or leaf in the current block also is recorded in the AD zone of FS page or leaf, and the picture pointer of edited result file C and AD are recorded in all the other pages or leaves (page or leaf except FS page or leaf and PP page or leaf does not wherein record the AV data as yet) (step S47).

In this step S47, the AD of edited result file C writes down by method shown in Figure 16.Promptly, in the page or leaf except the page or leaf of the picture pointer that records edited result file C, as in FS page or leaf shown in Figure 11, for example the zone of 1k byte is assigned to the zone that is used to write down as the address of the saturated FS page or leaf of search index, and the zone of all the other 127k bytes is assigned to the AD zone.Then, the AD that has write down the page or leaf of the AD of edited result file C and picture pointer is recorded in the AD zone, and in addition, the address of having write down all pages of AD is recorded in the search index zone.Figure 16 shows a kind of like this state,, has write down the AD of edited result file C in three pages that is.In these three pages, the address (being designated as the FS address) of verso is recorded in the search index zone of central leaf, and the address of verso and central leaf is recorded in the search index zone of recto.

As shown in figure 15, after step S47, in the memory of CPU 8, the content about the current FS address of bridge joint file of being stored is updated to the address of the FS page or leaf in the current block, in addition, the address of the page or leaf of the last AD that has write down edited result file C in step S47 also is stored in the memory of CPU 8, as the current FS address (step S48) about edited result file C.Then, termination.

In example shown in Figure 16, in step S48, in three pages of the AD that has write down edited result file C, the address of recto is stored as the current FS address about edited result file C.

If the answer among the step S41 is for being to judge then whether current block is last piece (step S49) that will write down the AV data of bridge joint file.

If the answer among the step S49 is for denying, then in current block, the AV data be recorded in except FS page or leaf and PP page or leaf the page or leaf in, and the picture pointer that has recorded the AV data in the piece (comprising current block) of AV data so far (here, when having saturated PP page or leaf, be the picture pointer of the AV data in the piece subsequently) by cumulative record in the PP page or leaf.In addition, the address of all saturated FS pages or leaves is recorded in the search index zone of FS page or leaf, and the AD of the AD of the AD of the AV data in the piece of being accumulated after the piece that has saturated FS page or leaf (comprising current block), the saturated PP page or leaf accumulated and the PP page or leaf in the current block is recorded in the AD zone of FS page or leaf (step S50).Then, processing advances to step S44.

If the answer among the step S49 is for being then to generate the picture pointer (corresponding to step S7 among Fig. 2) of edited result file C, the AD (step S51) of newly-generated as described above in addition whole edited result file C.

Then, in current block, the AV data be recorded in except FS page or leaf and PP page or leaf the page or leaf in, and the picture pointer that has recorded the AV data in the piece (comprising current block) of AV data so far (here, when having saturated PP page or leaf, be the picture pointer of the AV data in the subsequent block) by cumulative record in the PP page or leaf.In addition, the address of all saturated FS pages or leaves all is recorded in the search index zone of FS page or leaf, and the AD of the AV data in the piece of being accumulated after the piece that has saturated FS page or leaf (comprising current block), the AD of the saturated PP page or leaf accumulated and the AD of the PP page or leaf in the current block are recorded in the AD zone of FS page or leaf.In addition, the picture pointer of edited result file C and AD are recorded in all the other pages or leaves (page or leaf except PP page or leaf and FS page or leaf does not wherein record the AV data as yet), (step S52) as shown in figure 16.Then, processing advances to step S48.

By this recording processing, not merely for the filesystem information (AD) that writes down edited result file C and picture pointer and visit flash memory 4, but when the AV data of record bridge joint file, AD and the picture pointer of record edited result file C in last piece of record bridge joint file.Thereby, can be under the situation of additive decrementation main storage means capacity not filesystem information and the picture pointer of record edited result file C, keep the access performance (bit rates of the AV data during the recoding/reproduction) of flash memory 4 simultaneously.

In addition, still as shown in figure 16, by reading the current FS page or leaf of edited result file C, be stored in page or leaf in the search index zone of this current FS page or leaf by reading its address then, can obtain all AD of edited result file C, and can obtain to write down edited result file C all picture pointers the page or leaf AD.Thereby, can manage filesystem information and the picture pointer of edited result file C at an easy rate, keep the access performance of flash memory 4 simultaneously.

Here, in the above embodiment of the present invention, the present invention is applied to having the video server of editting function.But above-mentioned shearing editing and processing and recording processing can also be applied to the editing device except that video server.In addition, the recording processing of, AV data that Fig. 8 to 10 or Figure 11 to 13 describe by using and filesystem information can also be applied to AV data and filesystem information are recorded in the tape deck that does not have editting function.

It will be understood by those skilled in the art that in the scope of claims or its equivalent, can carry out various modifications, combination, sub-portfolio and change according to designing requirement and other factors.The cross reference of related application

The present invention comprises Japanese patent application JP2007-024679 and the relevant respectively theme of submitting to Japan Patent office with on February 2nd, 2007 of JP 2007-024681, and these two full contents in first to file are incorporated into this by reference.
