Embodiment
＜the first embodiment 〉
Explained later is according to the data handling system of first embodiment of the invention.
Fig. 1 is the overall arrangement figure of data handling system 1 according to an embodiment of the invention.As shown in Figure 1, data handling system 1 for example has computer 2 and transcriber 4.
[computer 2]
As shown in Figure 1, computer 2 has HDD 12, bridge 14, memory 16, bridge 18, operating equipment 19 and CPU 20.Note, control storage 16 storing predetermined programs (program of sixth aspect present invention), and CPU 20 reads and carries out this program and carries out following processing.Preset program can be stored in semiconductor memory or other memories 16, perhaps is stored in HDD, CD or other storage mediums.HDD 12 for example stores the reproduction data ENC according to MPEG scheme coding.Reproduction data ENC as shown in Figure 2 comprises a plurality of GOP (set of pictures) of sequential order decoding in the transcriber 4.In the example shown in Fig. 2, according to the order decoding of GOP (N-1), (N), (N+1), (N+2).Each GOP comprises I, P and B three class image datas (frame data).In addition, each GOP comprises single I image data.In the present embodiment, for example, used so-called " the long GOP " of the image data that in GOP, has relatively large number.
Here, the I image data is the image data of (in the frame) in the coded image, and independent decoded with respect to other image datas.In addition, the P image data is the image data of the frame of measurable coding on forward direction, and with reference to (previous DISPLAY ORDER) I or the P image data and decoded that are positioned in time in the past.Notice that " I and P image data " also is known as " anchor image data ".In addition, the B image data is the image data of the frame of measurable coding on both direction, and be positioned on the reference time front or back (preceding or at the back DISPLAY ORDER) I or P image data and decoded.Notice that the read-out speed of HDD 12 is lower than the maximum of transcriber 4 and reproduces speed.
Bridge 14 provides the expanded function of bridge 18, and has PCI expansion slot or IDE (integrated drive electronics) slot etc.Bridge 14 has and bridge 18 identical functions basically, but has the bandwidth narrower than bridge 18, and has the low access means of device rate that the ratio that is connected to it is connected to bridge 18.
[transcriber 4]
As shown in Figure 1, transcriber 4 for example have PCI bridge 30, input store 32, decoder 34_1 to 34_3, reproduction of storage 36_1 to 36_3, selector 38, control storage 40, CPU 42 and control bus 46.Note, control storage 40 storing predetermined programs (program of the present invention), and CPU 42 reads and carries out this program and carries out following processing.Preset program can be stored in semiconductor memory or other control storages 40, perhaps can be stored in HDD, CD or other storage mediums.
Decoder 34_1 receives the reproduction data ENC that reads by PCI bridge 30 as input according to the control of CPU 42 from input store 32, utilize the MPEG scheme that it is decoded, and the result is write among the reproduction of storage 36_1.Specifically, decoder 34_1 under the control of CPU 42 not the decoded result with reference to other image datas the I image data that reads in input store 32 is decoded.In addition, decoder 34_1 is positioned in time in the past and the decoded result of decoded I or P image data by reference, thereby the P image data among the GOP that reads from input store 32 is decoded under the control of CPU 42.In addition, decoder 34_1 under the control of CPU 42, by with reference in time preceding or at the decoded result of back and decoded I or P image data, thereby the B image data among the GOP that reads from input store 32 is decoded.Decoder 34_2 has the configuration identical with the configuration of decoder 34_1 with decoder 34_3, utilizes the MPEG scheme that the image data of importing via PCI bridge 30 is decoded, and writes results to reproduction of storage 36_2 and reproduction of storage 36_3.
To explain that below decoder 34_1,34_2 and 34_3 write decoded result the write method of reproduction of storage 36_1,36_2 and 36_3.As shown in Figure 3, each among reproduction of storage 36_1,36_2 and the 36_3 all has 8 memory bank zones " 0 " and arrives " 7 ".In the present embodiment, shown in Fig. 3 B and Fig. 4 A, Fig. 4 B, in 8 memory bank zones that in each of reproduction of storage 36_1,36_2 and 36_3, provide, " 0 " is arrived " 5 " totally 6 memory bank zones is in a fixed manner as the storage area of the decoded result of storage I and P image data, and " 6 " and " 7 " two memory bank zones are in a fixed manner as the storage area of the decoded result of storing the B image data.When to when the reproduction data ENC shown in Fig. 2 and Fig. 3 A decodes, decoder 34_1 for example arrives the memory bank zone " 0 " that image data and the I2 image data among the GOP (N) of I2, P5, P8, P11 and P14 among the GOP (N-1) are write among the reproduction of storage 36_1 shown in Fig. 3 B in " 5 ".In addition, decoder 34_2 for example arrives the memory bank zone " 0 " that image data and the I2 image data among the GOP (N+1) of I2, P5, P8, P11 and P14 among the GOP (N) are write among the reproduction of storage 36_2 shown in Fig. 4 A in " 5 ".In addition, decoder 34_3 for example arrives the memory bank zone " 0 " that image data and the I2 image data among the GOP (N+2) of I2, P5, P8, P11 and P14 among the GOP (N+1) are write among the reproduction of storage 36_3 shown in Fig. 4 B in " 5 ".
In addition, when the B image data among the GOP (N-1) was decoded, decoder 34_1 arrived the I of storage in " 5 " and the decoded result of P image data with reference to the memory bank zone " 0 " in reproduction of storage 36_1.
In addition, when the B image data among the GOP (N) was decoded, decoder 34_2 arrived the I of storage in " 5 " and the decoded result of P image data with reference to the memory bank zone " 0 " in reproduction of storage 36_2.
In addition, when the B image data among the GOP (N+1) was decoded, decoder 34_3 arrived the I of storage in " 5 " and the decoded result of P image data with reference to the memory bank zone " 0 " in reproduction of storage 36_3.
Selector 38 switches under the control of CPU 42 and reproduces selectively and export the decoded result that reads from reproduction of storage 36_1,36_2 and 36_3.
Processing below CPU 42 carries out based on program stored and data in control storage 40 is with the operation of centralized control transcriber 4.CPU 42 will write the input store 32 from the GOP (reproducing data ENC) of computer 2 inputs.In addition, CPU 42 operation dispatchings are determined to decode order in GOP unit of the image data among this GOP, to be reproduced in the reproduction data ENC of storage in the input store 32.CPU 42 for example reads from input store 32 with reference to I among the GOP (N-1) of the decoded result of I and P image data decoding and the B image data among P image data and the GOP (N) via PCI bridge 30, and it is outputed to decoder 34_1.Here, in the present embodiment, the B image data refers to the open GOP with reference to the decoded result decoding of the I of different GOP and P image data.Specifically, for example, B0 among the GOP shown in Fig. 3 A (N) and B1 image data are to decode with reference to the decoded result of I among the GOP (N-1) and P image data.Therefore, CPU42 outputs to decoder 34_1 with B0 among the GOP (N) and B1 image data.
In addition, CPU 42 for example reads from input store 32 with reference to I among the GOP (N) of the decoded result of I and P image data decoding and the B image data among P image data and the GOP (N+1) via PCI bridge 30, and it is outputed to decoder 34_2.In addition, CPU 42 for example reads from input store 32 with reference to I among the GOP (N+1) of the decoded result of I and P image data decoding and the B image data among P image data and the GOP (N+2) via PCI bridge 30, and it is outputed to decoder 34_3.
Before the reproduction initiation command that receives from the CPU 20 of computer 2, CPU 42 for example regularly just makes decoder 34_1,34_2 and 34_3 carry out decoding up to the X that is ready to complete shown in Fig. 3 B and Fig. 4.As a result, receive timing place from the reproduction initiation command of CPU 20 at CPU 42, the I of GOP (N-1), GOP (N) and GOP (N+1) and the decoded result of P image data are stored in reproduction of storage 36_1 to 36_3.In addition, when receiving the reproduction initiation command of putting from the appointment reproduction of computer 2, CPU 42 control decoder 34_1,34_2 and 34_3 to the decoding of B image data, from reproduction of storage 36_1,36_2 and 36_3 to the read operation of selector 38 and the selection operation of selector 38, so that reproduce and output is reproduced point from this and carried out with the speed of the direction appointment of appointment.
Below with the example of the operation of the data handling system 1 shown in the key-drawing 1.
＜the first operation example 〉
Explained later is reproduced and the example of operation during output to carrying out at transcriber 4 when computer 2 is specified the image data of wanting reproduced.Fig. 5 is the flow chart that is used to explain this operation example.
Step ST1:
The CPU 20 of computer 2 judges that whether indication is used to specify the operation signal of the operation of reproducing the reproduction point among the data ENC from operating equipment 19 inputs.It is designated when judging, and then advances to step ST2, and when judging when not designated as yet the processing of repeating step ST1.
Step ST2:
The CPU 20 of computer 2 reads the GOP that is included in the image data of the reproduction point of appointment the step ST1 and GOP on every side (that is, 3 (a plurality of) GOP) altogether from HDD 12, and by bridge 18 and pci bus 6 they is outputed to transcriber 4.Transcriber 4 will be write the input store 32 from the GOP of computer 2 inputs by PCI bridge 30.
Step ST3:
CPU 42 operation dispatchings of transcriber 4 are determined to decode order in GOP unit of the image data among this GOP, to be reproduced in the reproduction data ENC of storage in the input store 32.Then, CPU 42 by using for example Fig. 3 and Fig. 4, reads the image data that is included among the GOP that is stored in the input store 32 as mentioned above, and it is outputed to decoder 34_1,34_2 and 34_3 based on the result of scheduling.Then, decoder 34_1,34_2 and 34_3 carry out decoding as mentioned above, and decoded result is write reproduction of storage 36_1,36_2 and 36_3.Like this, (shown in being ready to complete among Fig. 3 B and Fig. 4) before transcriber 4 receives reproduction initiation command from computer 2, the I of GOP (N-1), GOP (N) and GOP (N+1) and the decoded result of P image data have been stored in reproduction of storage 36_1 to 36_3.
After the write operation in the fixed storage body region of the decoded result of I and P image data being write among reproduction of storage 36_1,36_2 and the 36_3, when through time of the data of 1 pictures (1 frame) that is used to decode, transcriber 4 can reproduce and export will be processed GOP in any image data.That is, in the decode time of 1 pictures, the image data of point is reproduced in any appointment among the GOP can reproduced and output, and the back will make an explanation to this in step ST6.For example, when the B9 image data among the GOP (N-1) is decoded, reproduced and exports, require the P8 among the GOP (N-1) and the decoded result of P11 image data.In addition, for the P8 image data of decoding, require the decoded result of P5 image data, and, require the decoded result of I2 image data in order to decode the P5 image data.
That is,, require the decoded result of I2, P5, P8 and P11 image data for the B9 image data of decoding.According to transcriber 4, shown in Fig. 3 B, by storage I and P image data in reproduction of storage 36_1, when decoder 34_1 receives the B9 image data of GOP (N-1), by use P8 and the P11 image data of storing in the memory bank zone " 2 " of reproduction of storage 36_1 and " 3 ", decoder 34_1 can carry out decoding, reproduction and the output of B9 image data fast.Transcriber 4 shown in Fig. 1 has decoder 34_1,34_2 and 34_3 totally 3 decoders, therefore can reproduce and export the image data of 3 GOP in the processing time of 1 pictures data.
For example, because transcriber 4 has been stored the image data of 3 GOP as shown in Figure 3A in input store 32, when the CPU 20 of computer 2 reproduces initiation command to the CPU of transcriber 4 42 outputs, when being used for the 5th picture (frame) the conduct reproduction point of regulation GOP (N), it just begins to reproduce fast also output image according to the image data at the 5th picture place.Like this, can reproduce (frame feed reproduction) according to reproduction initiation command execution scouring reproduction (scrub reproduction) and frame feeding with extraordinary response from computer 2.In addition, input store 32 has been stored the image data of 3 GOP, therefore, is changed above GOP even reproduce point, also can avoid the reproduction and the output delay that are sent to transcriber 4 and decode and caused from computer 2 owing to image data.
Step ST4:
The CPU 20 of computer 2 judges whether to have imported the operation signal that indication specifies the reproduction initiation command of reproduction point to operate from operating equipment 19.When judging when having imported, advance to step ST5, and when judging when not importing as yet the processing of repeating step ST4.
Step ST5:
The CPU 20 of computer 2 will specify the reproduction initiation command that reproduces starting point to output to transcriber 4.
Step ST6:
CPU 42 control decoder 34_1, the 34_2 of transcriber 4 and the decoding of 34_3, from reproduction of storage 36_1,36_2 and 36_3 to the read operation of selector 38 and the selection operation of selector 38, so that reproduce and output from carrying out with the speed of the direction appointment of appointment by the reproduction starting point of reproducing the initiation command indication.Like this, transcriber 4 begins to carry out reproduction and output from reproducing point.
＜the second operation example 〉
Will be explained in the specific example that transcriber 4 reproduces and export the operation of the image data that reproduces the some place below.Note, here, will make an explanation by the decoding that is illustrated in decoder 34_1 place.Fig. 6 is the flow chart that is used for the interpreter operation example.
Step ST21:
The CPU 42 of transcriber 4 identifies based on the reproduction point that is indicated by the reproduction initiation command from computer 2 input and reproduction status of processes will be by the image data that next reproduces and export.Then, CPU 42 judges that the anchor image data of the image data that is identified is whether decoded and is stored among reproduction of storage 36_1,36_2 and the 36_3, advances to step ST23 when being stored when judging, otherwise advance to step ST22.Notice that in the present embodiment, the anchor image data is an image data of wanting the decoded result of decoded image data with reference to the next one of appointment.
Step ST22:
The anchor image data of the image data that CPU 42 will identify in step ST21 reads decoder 34_1,34_2 and 34_3 decodes from input store 32.Like this, the decoded result of anchor image data is stored among reproduction of storage 36_1,36_2 and the 36_3.
Step ST23:
CPU 42 judges whether the decoded result of the image data that identifies is stored among reproduction of storage 36_1,36_2 and the 36_3 in step ST21, when judging them and be stored, advance to step ST25, otherwise advance to step ST24.
Step ST24:
Decoder 34_1,34_2 and 34_3 are as required by coming the image data that identifies in step ST21 is decoded with reference to the decoded result of storing in reproduction of storage 36_1,36_2 or 36_3.
Step ST25:
The CPU 42 of transcriber 4 makes selector 38 be chosen in the decoded result of the image data of selecting among the step ST1, reproduces and exports this result.
Step ST26:
The I of the anchor image data of GOP on every side of the GOP under the image data of selecting is formed in CPU 42 judgements of transcriber 4 in step ST1 and whether the decoded result of P image data is stored among reproduction of storage 36_1,36_2 and the 36_3, when judging them and be stored, finish this processing, otherwise, advance to step ST27.
Step ST27:
The CPU 42 of transcriber 4 reads anchor image data with respect to the GOP in next DISPLAY ORDER of the GOP under the image data of selecting from input store 32 among step ST1, and it is outputed to decoder 34_1,34_2 and 34_3.
Step ST28:
The CPU 42 of transcriber 4 is to the beginning of the CPU of computer 2 20 decodings of notice in step ST27.
Step ST29:
The CPU 20 of computer 2 reads from HDD 12 and is not stored in image data in the input store 32 as yet in the image data that belongs to the decoded GOP of among step ST28 beginning, it is outputed to transcriber 4, and make transcriber 4 that it is write input store 32.
