Next, in copyright management server 300, copyright management server transmission unit 301 receives (sending from the transmission unit between the server of playlist synthesis server 100 103) content identification information and checks authority information, from copyright information memory 311, obtain corresponding to content identification information and the copyright information of checking authority information, and send copyright informations (S1409) to playlist synthesis server 100.
For example, in copyright management server 300, suppose that copyright information shown in Figure 8 is stored in the copyright information memory 311, received content identification information " A30657 " and check authority information from playlist synthesis server 100.In the case, check that the segmentation identification information that comprises in the authority information is " 1 ".Correspondingly, in the copyright information with the content identification information " A30657 " that is stored in the copyright information memory 311, the part that will have the copyright information of segmentation identification information " 1 " sends in the playlist synthesis server 100.
In addition, from the 103 received content identification informations of the transmission unit between the server of playlist synthesis server 100, all copyright informations corresponding to content identification information can be sent to playlist synthesis server 100 by only.In the case, the copyright information memory 111 of playlist synthesis server 100 need have been stored the data structure of segmentation identification information.
Next, in playlist synthesis server 100, the transmission unit 103 between the server receives the copyright information (S1410) that sends from the copyright management server transmission unit 301 of copyright management server 300.
After copyright information memory 111 obtains copyright information (S1407) or after copyright management server transmission unit 301 receives copyright informations (S1409), the playlist synthesis unit 101 synthetic playlists (S1411) that can check.Tell about the building-up process of the playlist that can check after a while.
After the synthetic playlist that can check, terminal server transmission unit 102 checks that to video terminal 200 sends the playlist (S1412) that can check.
Next, check in the terminal 200 at video, 202 receptions of terminal transmission unit are by the playlist of checking (S1413) of terminal server transmission unit 102 transmissions of playlist synthesis server 100, and synthetic request is synthesized and the process of the playlist that reception can be checked is finished.
Below, check in the terminal 200 that at video the playlist playlist that can check is stored in the playlist memory 214 that can check, and can use the playlist that can check.In addition, broadcast unit 203 can come play content according to the playlist that can check.
Next, describe the building-up process of the playlist of checking among the S1411 in detail.Figure 15 is the flow chart according to the building-up process of the playlist of checking of first embodiment.
The playlist synthesis unit 101b that at first, can check obtains first start bit from the playlist corresponding to the playlist identification information that receives and puts and first end position (S1501).For example, in playlist shown in Figure 6, obtaining " 25:30:50 " and " 27:13:00 " puts and first end position as first start bit.
The playlist synthesis unit 101b that next, can check checking from copyright information obtained first start bit in the restriction section and put and first end position (S1502).For example, in copyright information shown in Figure 12, obtaining " 00:00:00 " and " 04:59:99 " puts and first end position as first start bit.In the case, based on specifying basis (" 0 " or " 1 "), from the left side of segment information to or the right side to extracting original position and end position.In Figure 12, specifying the basis is " 0 ".Correspondingly, extract original position and end position from left side centering.
The playlist synthesis unit 101b that next, can check judges original position and end position and original position of obtaining and the end position overlapping (S1503) that obtains in S1502 in S1501.In the case, overlapping not only the expression fully mated by two sections that two original positions and two end positions are represented, but also represents that two sections partly mate.
If judge two sections not overlapping (in S1503, being "No"), then needn't specify rule corresponding to the copyright information of this section.Correspondingly, judge whether to handle all segment informations (S1511).
In Figure 13, original position and the end position that obtains from playlist is " 25:30:50 " and " 27:13:00 ".On the other hand, in Figure 12, original position and the end position that obtains from copyright information is " 00:00:00 " and " 04:59:99 ".Correspondingly, these two sections are not overlapping.In Figure 12, for original position and end position (" 23:00:00 " and " 27:59:99 ") corresponding to segment number " 7 ", these two sections are at first overlapping.Correspondingly, thitherto, repeat the processing of S1502, S1503 and S1511.
If judge two sections overlapping (in S1503, being "Yes"), check then that restriction section acquiring unit 101a calculates to check the individual copyright information that comprises in the authority information (receiving) and corresponding to each the summation (S1504) of logic product between the information of the appointment copyright of obtaining of checking the restriction section by terminal server transmission unit 102.
For example, if individual copyright information is " 010 ", specifying the information of copyright is " 111 ", and primary logic product is " 1 ", and deputy logic product is " 1 ", and tertiary logic product is " 0 ".As a result, the summation of the logic product of each all is " 1 ".
Next, check that restriction section acquiring unit 101a judges whether summation is not less than " 1 " (S1505).If summation is lower than " 1 " (being "No" in S1505), then needn't specify rule corresponding to the copyright information of this section.Correspondingly, judge whether to handle all segment informations (S1511).
If summation is not less than " 1 " (in S1505 for "Yes"), check restriction section acquiring unit 101a judge check the section information extraction that comprises in the authority information (in S1403, receiving) by terminal server transmission unit 102 whether be " 0 " (S1506).
If a section information extraction is " 0 " (being "Yes" in S1506), check that then restriction section acquiring unit 101a is provided with the original position of the view segment that is shown by playlist and the original position and the end position (S1507) of the playlist that the end position conduct can be checked.
If a section information extraction is not " 0 " (in S1506 for "No"), check that then restriction section acquiring unit 101a is provided with the original position of checking restriction described in the copyright information and end position original position and the end position (S1508) as the playlist that can check.
The playlist structural unit 101b that next, can check obtains corresponding to the contents processing (S1509) in the copyright Rule Information of handling of checking the restriction section.For example, obtain corresponding to the connection in the copyright Rule Information of checking the restriction section, order and appointment basis.Based on these values, obtain contents processing shown in Figure 9.
For example, in Figure 12, when handle corresponding to segment number " 7 " check restriction section (" 23:00:00 " and " 27:59:99 ") time, obtain connections " 1 ", " 1 " and appointment basic " 0 " be as the copyright Rule Information in proper order.As shown in Figure 9, the contents processing that is obtained corresponding to these values is " to have confirmed not exist after checking the restriction section and concerned view segment.Under situation about existing, concern that view segment moves according to the order of the segmentation of content ".
Next, the contents processing of execution graph 7 (appointment).For example, the playlist synthesis unit 101b that can check carries out and concerns the insertion of view segment or layout again, and will concern that view segment adds the playlist (S1510) that can check to.
For example, in Figure 12,, suppose to have obtained contents processing and " confirm after checking the restriction section, not exist and concern view segment for limiting section (" 23:00:00 " and " 27:59:99 ") corresponding to checking of segment number " 7 ".Under situation about existing, concern that view segment moves according to the order of the segmentation of content." in the case, concern that view segment is " 00:00:00 " and " 04:59:99 " described in the right side of checking the restriction section.In the case, shown in the playlist of Fig. 6, second section with concern view segment overlapping " 00:00:00 " and " 03:30:00 ".Correspondingly, based on the contents processing of Fig. 9, rearrange first section and second section, and add the playlist that to check to by replacement.
The playlist synthesis unit 101b that next, can check judges whether to handle all and checks restriction section (S1511).Do not check restriction section (in S1511, being "No") if also handle all, then obtain the next one and check the restriction section, and repeat to handle (S1502).
Check restriction section (being "Yes" in S1511) if handled all, the playlist structural unit 101b that then can check has judged whether to handle all original positions and the end position (S1512) in the playlist.
If also do not handle all original positions and end position (in S1512, being "No"), then obtain next original position and end position, and repeat processing (S1501).
If handled all original positions and end position (being "Yes" in S1512), then the synthetic of the playlist that can check finished dealing with.
Next, tell about the playlist Composite Display that to check, the playlist display curtain that can check and playlist Composite Display.At first, suppose the synthetic playlist that can check, check composition playlist in the terminal 200 at video.In the case, the tabulation Composite Display that displays the play.
Figure 16 is the schematic diagram of an example of playlist Composite Display.As shown in figure 16, playlist Composite Display 1601 comprises action button 1611, content choice button 1613 and the playlist viewing area 1620 of video time zone 1603, the start-up time registration button 1604, concluding time registration button 1605, broadcast/stop/pause/rewinding of the reproduction time of content viewing area 1602, content/forward.
Under the situation of composition playlist, at first, by click on content selector button 1613, displaying contents is selected screen (telling about after a while), and chosen content is as the synthetic source of playlist from the content choice screen.Next, with first frame (start-up time) of the cursor section of moving on to, so that extract by action button 1611.By click registration button start-up time 1604, register start-up time.Equally, by second frame (concluding time) of action button 1611 with the cursor section of moving on to.By clicking concluding time registration button 1605, the registration concluding time.Each section for extracting repeats this operation.After the extraction of finishing all sections, synthesize button 1612 by clicking playlist, composition playlist, and be stored in the terminal plays list memory 213.From the section composition playlist of the extraction of Figure 16 and be stored under the situation the terminal plays list memory 213, Fig. 6 has shown this playlist.
Figure 17 is the schematic diagram of an example of content choice screen.As shown in figure 17, content choice screen 1701 comprises viewing area 1702, with content, selection data display area 1703, judgement button 1704 and the cancel button 1705 that shows storage by different level.
By selecting the content on the viewing area 1702 and click and judge button 1704, judge to be used for the content of composition playlist.Turn back to the playlist Composite Display by clicking cancel button 1705, handling.
Next, check in the terminal 200, tell about and select playlist as the synthetic source of the playlist that can check and show the playlist Composite Display of checking of the synthetic playlist that can check at video.Figure 18 is the schematic diagram of an example of the playlist Composite Display that can check.
As shown in figure 18, the playlist Composite Display 1801 that can check comprises playlist content viewing area, be used to show the existing playlist that receives from playlist synthesis server 100, check box 1803, be used to select playlist, the playlist that can check synthesizes button 1804, is used to ask the playlist synthesis server 100 synthetic playlists that can check.
By confirming the content of shown playlist, the user chooses the user to wish to be used for the check box 1803 of playlist of the synthetic playlist that can check, and clicks the synthetic button 1804 of the playlist that can check.So, the playlist of checking of synthetic playlist in user-selected.
Next, tell about and be used to show by the synthetic playlist display curtain of checking of playlist synthesis server 100.Figure 19 is the schematic diagram that video is checked an example of the playlist display curtain of checking on the terminal 200.
On the playlist display curtain that can check, after sending the synthetic request of the playlist that to check by the playlist Composite Display that can check, by receiving the playlist of checking that synthesizes by playlist synthesis server 100, the content of the playlist that demonstration can be checked.
As shown in figure 19, the playlist display curtain 1901 that can check comprises plays segment display region 1902, all broadcast sections that are used for displaying contents, the segment display region 1903 that can check is used for showing the section that can check by oblique line, corresponding to the thumbnail image 1904 of the segment display region 1903 that can check, check box 1905, be used to point out the playlist of checking that will download, download button 1906 is used to download the pointed playlist of checking.
So, the playlist display curtain 1901 that can check visually shows the playlist of checking of checking the authority information coupling with each user.Correspondingly, the user can understand the content of the playlist that can check like a cork.In addition, each user's the authority information of checking is sent to playlist synthesis server 100, and download is also used the playlist that can check, as the playlist based on the editor who checks authority information.Correspondingly, can be according to the shown playlist play content of checking.
In the prior art, before the synthetic playlist that can check, visually show the existing playlist that synthesizes by another user, from existing playlist, select the desirable playlist of user, from the synthetic playlist that can check of selected playlist.In the case, usually come play content according to the playlist that is different from shown playlist.Yet, in first embodiment, such problem can not take place.
Next, the example of the building-up process of the playlist that can check of detailed description.In this example, newly synthesizing playlist shown in Figure 6 and after playlist synthesis server 100 registration playlists (playlist identification information " 1 " is assigned to playlist), synthesizing the playlist that to check from playlist.Suppose not to be stored in the playlist memory 112 corresponding to the playlist of checking of playlist identification information (checking terminal 200 by video), the copyright information of content is not stored in the copyright information memory 111.In addition, in copyright management server 300, registered copyright information shown in Figure 8.
At first, check that from video terminal 200 sends playlist identification information " 1 " shown in Figure 3 and checks authority information (S1402), and receive (S1403) by playlist synthesis server 100.
105 retrievals of playlist retrieval unit are corresponding to the playlist of checking of the information that receives.In the case, there be not (being "No" in S1404) in the playlist that can check.Correspondingly, copyright information retrieval unit 104 is retrieved the copyright information corresponding to the information that receives from copyright information memory 111, and judges whether to exist copyright information (S1406).
In this example, in playlist synthesis server 100, there is not copyright information (in S1406, being "No").Correspondingly, the transmission unit between the server 103 sends content identification information " A30657 " (corresponding to playlist identification information " 1 ") shown in Figure 3 and checks authority information (S1408) to copyright management server 300.
In Fig. 3, check that the segmentation identification information that comprises in the authority information is " 1 ".Correspondingly, copyright management server 300 obtains the part with segmentation identification information " 1 " from copyright information shown in Figure 8, and this part is sent to playlist synthesis server 100 (S1409).
By receiving the part (S1410) of copyright information, the playlist synthesis server 100 synthetic playlists (S1411) that can check.
At first, from playlist shown in Figure 6, obtain first start bit and put and first end position (" 25:30:50 " and " 27:13:00 ").Next, what comprise from the copyright information that receives checks in the restriction section, according to the order of segment number, retrieval have with first start bit put with overlapping original position of first end position and end position check the restriction section.
In this example, from copyright information, extract checking of segment number " 7 " and limit section.Next, calculating chart 3 check the individual copyright information " 010 " that comprises in the authority information and corresponding to the summation (S1504) of the logic product between the information " 111 " of the appointment copyright of segment number " 7 ".Summation is " 1 " (being "Yes" in S1505), and carries out the deterministic process (S1506) of section information extraction.
In Fig. 3, check that the section information extraction that comprises in the authority information is " 1 " (being "No" in S1506).Correspondingly, original position that checking restriction section described in the copyright information and end position are set to the original position and the end position (S1508) of the playlist that can check.For example, original position in the copyright information " 23:00:00 " and end position " 27:59:99 " are added to (they are not original position " 25:30:50 " and end position " 27:13:00 " in the playlist) in the playlist that can check.
Then, obtain contents processing (S1509) corresponding to the copyright Rule Information.In the copyright Rule Information corresponding to segment number " 7 ", connection is " 1 ", and order is " 1 ", and specifying the basis is " 0 ".As shown in Figure 9, the contents processing as corresponding to these values has obtained and " has confirmed not exist after checking the restriction section and concerned view segment.Under situation about existing, concern that view segment moves according to the order of the segmentation of content.”
This handle content be forbid original position " 25:30:50 " and end position " 27:13:00 " exist afterwards original position " 00:00:00 " and end position " 04:59:99 " section rule.Playlist shown in Figure 6 does not meet this rule.Correspondingly, the replacement of carrying out the order of these two sections is handled.In this example, change the order of two sections, so that before the section of original position " 25:30:50 " and end position " 27:13:00 ", play the section of original position " 00:00:00 " and end position " 04:59:99 ".
Then, another that judges whether to exist next appointment checked restriction section (S1511).In the case, segment number " 7 " is last numbering (being "Yes" in S1S11).Correspondingly, from playlist, obtain next original position " 00:00:00 " and next end position " 03:30:00 ", and repeat said process (S1512, S1501).
Detailed process below having omitted.For second section of original position in the playlist " 00:00:00 " and end position " 03:30:00 ", specified section is numbered the copyright Rule Information of " 1 ".In the case, added the section of original position " 10:00:00 " and end position " 10:59:99 ".
In addition, for the 3rd section of original position in the playlist " 12:00:00 " and end position " 13:48:59 ", specified section is numbered the copyright Rule Information of " 5 ".In the case, added the section of original position " 22:00:00 " and end position " 22:59:99 ".
At last, the synthetic playlist of checking shown in Figure 20, and send to video and check terminal 200 (S1412).By the playlist of Fig. 6 and the playlist of checking of Figure 20 are compared, can understand the special characteristic of the playlist that can check like a cork.In simple terms, when when (synthesizing), having added another section of checking based on the synthetic playlist that can check of the playlist of Fig. 6, or move certain section position with certain section by the user by method referred to above.As a result, as shown in figure 20, the synthetic playlist of checking that meets the copyright information that is provided with by the copywriter.
So, in first embodiment, to the condition (being provided with) of copyright management server 300 registration viewing content by the copywriter.User's synthetic video is checked the playlist in the terminal, and to playlist synthesis server 100 registration playlists.Based on user's the condition of checking and playlist, the playlist synthesis server 100 synthetic playlists of checking that meet two conditions.Correspondingly, the playlist of checking that has high practicability for the user can be synthesized, the copyright of content can be protected simultaneously again.In addition, can be from the synthetic qualified playlist of checking of the playlist that synthesizes by another user.Correspondingly, can between a plurality of users, share playlist.
In the Content Management System of first embodiment, check between terminal 200 and the copyright management server 300 at video and to have prepared playlist synthesis server 100, the playlist synthesis server 100 synthetic playlists that can check.On the other hand, at second, third, and in the Content Management System of the 4th embodiment, the synthetic playlist that can check under the situation that does not have playlist synthesis server 100.
Figure 21 is the schematic diagram that has shown according to the assembly of the Content Management System of second, third and the 4th embodiment.As shown in figure 21, in Content Management System, video checks that terminal 2100 (2110,2120) and video check that terminal 2200 (2210,2220) links together by network 10.In addition, video is checked terminal 2100 (2110,2120), and video is checked terminal 2200 (2210,2220), and copyright management server 2300 (2310,2320) links together by network 20.In Figure 21, check that to video terminal 2100 (2110,2120) and video check that terminal 2200 (2210,2220) distributed different numberings, because a terminal is that video is checked side, another terminal is the synthetic side of playlist that can check.Yet each terminal all has identical functions.
In second embodiment, first video check terminal 2200 (being used for viewing content) with playlist identification information (identifying playlist uniquely) and user check that authority information sends to second video and checks terminal 2100, this terminal storage corresponding to the playlist of playlist identification information.Second video checks that terminal 2100 is based on checking that authority information and copyright information (being stored in advance in the copyright information memory) edit playlist, and the playlist that can check sends to first video and checks terminal 2200 as the edited result of playlist.After based on the playlist viewing content that can check, first video is checked the playlist that terminal 2200 can be checked and is checked that authority information sends to copyright management server 2300.Correspondingly, although always check that by second video synthetic playlist of checking of terminal 2100 is not reliable, still, first video checks that terminal 2200 can confirm still whether the content of being checked has invaded copyright.
In the 3rd embodiment, first video check terminal 2210 (being used for viewing content) with playlist identification information (identifying playlist uniquely) and user check that authority information sends to second video and checks terminal 2110, this terminal storage corresponding to the playlist of playlist identification information.Second video checks that terminal 2110 is based on checking that authority information and copyright information (being stored in advance in the copyright information memory) edit playlist, and the playlist that can check sends to first video and checks terminal 2210 as the edited result of playlist.Although come viewing content based on the playlist that can check,, first video is checked what whether terminal 2210 affirmation contents by rights made up.
In the 4th embodiment, first video checks that terminal 2220 (being used for viewing content) checks that from second video of having stored playlist terminal 2120 receives playlists.First video checks that terminal 2220 edits playlist based on user's check authority information and copyright information (being stored in advance in the copyright information memory), and as the edited result of playlist, the synthetic playlist that can check.First video checks that terminal 2220 sends the playlist that can check and checks authority information to copyright management server 2320.Copyright management server 2320 confirms whether the playlist that can check is synthetic based on copyright information.
In second, third and the 4th embodiment, video checks that terminal 2100,2110,2220 is with the synthetic playlist that can check of the mode different with first embodiment.In the case, the playlist that can check whether be based on copywriter's intention and synthetic be unclear.Correspondingly, whether the playlist that can check of affirmation meets and checks authority information.In simple terms, prepared the audit function of the playlist that can check.
Second, third and the 4th embodiment are described below in order.At first, tell about second embodiment.Figure 22 is that the video in the Content Management System of second embodiment is checked terminal 2100 and 2200 and the block diagram of copyright management server 2300.
Video checks that terminal 2100 and 2200 comprises that video checks that synthetic processing unit 2500 of processing unit 2400, playlist and end side check processing unit 2600.Video checks that processing unit 2400 carries out each function that the video of first embodiment shown in Figure 2 is checked terminal 200.Correspondingly, omitted its explanation.In addition, the synthetic processing unit 2500 of playlist is carried out each function of the playlist synthesis server 100 of first embodiment shown in Figure 10.Correspondingly, omitted its explanation.The video of (video is checked terminal 2100 or 2200) checks that processing unit 2400 can be connected to the synthetic processing unit 2500 of playlist of (another video is checked terminal 2200 or 2100) by network 10.
End side inspection processing unit 2600 is carried out and is checked the relevant process of end side (2100 or 2200) with video, checks the playlist of checking that the broadcast unit 203 of processing unit 2400 is utilized so that check video.End side checks that processing unit 2600 can be connected to copyright management server 2300 by network 20.
In the foregoing management system, video checks that the video of terminal 2200 (being used for viewing content) checks that processing unit 2400 checks the playlist that synthetic processing unit 2500 requests of playlist of terminal 2100 (having stored the playlist that utilizes for the user) can be checked from another video.Check at video obtain and play the playlist that can check in the terminal 2200 after, end side checks that processing unit 2600 and server side check that processing unit 2800 checks the legitimacy of the playlist that can check.In second embodiment, carry out this inspection by copyright management server 2300.
Next, tell about the checking process of the playlist that can check with reference to figure 23-25.Figure 23 is the functional block of the checking process in the Content Management System.
End side checks that processing unit 2600 comprises inspection message acquiring unit 2610 and inspection message transmitting element 2620.Before playing, in playing process, or after playing, inspection message acquiring unit 2610 obtains the playlist that can check from broadcast unit 203.In addition, inspection message acquiring unit 2610 obtains from check authority information memory 211 and checks authority information.Inspection message transmitting element 2620 sends the playlist that can check and checks authority information to copyright management server 2300.
In second embodiment, the data structure of the playlist that can check is different from first embodiment shown in Figure 20.Figure 24 is the schematic diagram of data structure of the playlist of checking of second embodiment.As understanding like a cork by Figure 24 and Figure 20 being compared institute, in the playlist of checking of second embodiment, whether except the playlist of checking of first embodiment, having described and having identified each section is the specified section identification information of checking the restriction section of copyright information.At the specified section identification information is under the situation of " 1 ", and section is the view segment described in the playlist, need not to specify copyright information.At the specified section identification information is under the situation of " 0 ", and section is to check the restriction section described in the copyright information.Playlist synthesis unit 101 by the synthetic processing unit 2500 of playlist is specified " specified section identification information ".
In copyright management server 2300, server side checks that processing unit 2800 comprises end message memory 2810, checks playlist judging unit 2820, playlist confirmation unit 2830 and illegal playlist memory 2840.Check the copyright information retrieval unit 302 output retrieval request of playlist judging unit 2820, and obtain result for retrieval from copyright information memory 311 to copyright management processing unit 2700.
Check playlist judging unit 2820 regularly or aperiodically many from be stored in end message memory 2810 and obtain copyright information to the playlist that can check with check in the authority information and select singly corresponding to the content identification information that comprises in the selected playlist of checking.
When playlist confirmation unit 2830 based on check authority information confirm the playlist that can check be not synthesize the time, the playlist that illegal playlist memory 2840 storages can be checked.
Figure 25 is the flow chart according to the checking process of the playlist of checking of second embodiment.
At first, obtain the specified section identification information (S1600) of the playlist that can check.In Figure 24, put " 00:00:00 " and first end position " 04:59:99 " for first start bit, obtain specified section identification information " 1 ".
Next, the value of judging the specified section identification information whether be " 1 " (S1601).(be "No" in S1601) under the situation that is not " 1 ", this section is the view segment described in the playlist, is not based on the section that copyright information adds.Correspondingly, needn't check this section.
Under the situation that is " 1 ", (in S1601, be "Yes"), obtain original position and end position (S1602).For example, in Figure 24, obtain " 00:00:00 " and " 04:59:99 ".
Next, obtain the original position and the end position (S1603) of copyright information.For example, in the copyright information of Figure 12, obtain first start bit and put " 00:00:00 " and first end position " 04:59:99 ".
Next, judge the original position of the playlist of checking in S1602, obtain and end position whether with the original position and the end position overlapping (S1604) of checking the restriction section of the copyright information that in S1603, obtains.
In above-mentioned example, original position and the end position that obtains from the playlist that can check is " 00:00:00 " and " 04:59:99 ".On the other hand, original position and the end position that obtains from copyright information is " 00:00:00 " and " 04:59:99 ".Correspondingly, judge that these original positions and end position are overlapping.
Next, calculate (check and comprise in the authority information) individual copyright information and specify the summation (S1605) of the logic product of each between the information (checking restriction section) of copyright corresponding to what comprise in the copyright information.
Judge whether summation is not less than " 1 " (S1606).Be lower than in summation under the situation of " 1 " and (in S1606, be "No"), needn't check and check the restriction section, because do not specify rule corresponding to the copyright information of checking the restriction section.In the case, judge whether to handle all segment informations (S1610).
