Description

  The present invention relates to an editing apparatus and program capable of writing content to a recording medium.

  Since digital content can be copied without deterioration in image quality, a copy control system has been introduced from the viewpoint of copyright protection.

  When the copy control system assigns information (copy control information) indicating the permitted number of copies to the content and copies the content to a recording medium of another system, the copy permitted number is subtracted by the number of times of copying. This is a mechanism for limiting the number of times content is copied. Examples of copy control information include copy once, dubbing 10 and the like.

  When the copy control information is copy once, the content can be moved to the recording medium of another system only once. In the case of dubbing 10, the content can be copied to the recording medium of the other system up to nine times, and can be moved to the recording medium of the other system only once. “Move” means erasing the corresponding content in the recording medium of the own system after copying the content to the recording medium of the other system.

  However, in a system that implements the above-described copy control system, if there is an “overlap section” as shown in FIG. A typical implementation is to subtract the allowable number of copies of the entire content (all sections) by the number of copies of “overlapping section”. The editing section shown in FIG. 7 (b) shows a state after the editing section is selected twice as shown in FIG. 7 (a). In FIG. 7A, the first time selects the editing section; A1, and the second time selects the editing section; A2. That is, in the “overlapping section” shown in FIG. 7B, two editing sections; A1 and A2 overlap. Therefore, in many systems, when content having an “overlapping section” as shown in FIG. 7B is copied to a recording medium of another system, the allowable copy count is subtracted twice. Become. For this reason, if there is an “overlapping section” as shown in FIG. 7B in the editing section selected at the time of editing the content, the right of the number of copies is wasted against the user's will. Sometimes.

  As a result, for example, in the case of content with copy-once copy control information, if there is an “overlapping section” as shown in FIG. As a result, editing may fail or the edited content cannot be moved to a recording medium of another system.

  For this reason, it is necessary to develop a mechanism that avoids wasting the right of the number of times of copying content.

  In addition, as a technical document filed prior to the present invention, there is a document that discloses a technique for performing various controls using copy control information included in broadcast content (for example, a patent document). 1).

In the above-mentioned patent document 1, it is possible to add a chapter mark to a change point of copy control information of broadcast content, and to record / play / delete / edit / move the content using the chapter mark and copy control information. I have to.
JP 2006-179149 A

  However, the above-mentioned Patent Document 1 neither describes nor suggests the necessity of avoiding wasteful consumption of the right to copy the content.

  An object of the present invention is to provide an editing apparatus and a program that can avoid wasting the right of the number of times of copying of content, which is the above-described problem.

As the second recording medium 200, an HDD, a DVD, or the like is applicable. The second recording medium 200 of this embodiment is assumed to exist in another system. For this reason, the writing control means 12 performs control so as to subtract the allowable copy number of the content when the content of the first recording medium 21 is written to the second recording medium 200.

<Processing of editing apparatus 100>
Next, the processing operation of the editing apparatus 100 according to the present embodiment will be described with reference to FIGS.

  When the editing operation of the content recorded on the first recording medium 21 is started (Start), the editing section selection means 110 starts selecting the editing section (Step S1), and the first recording medium 21 is started. The editing section of the content to be edited is selected from the contents recorded in (Step S2). For example, as shown in FIG. 3A, the first time selects the editing section; A1, and the second time selects the editing section; A2. Then, the editing section selection unit 110 ends the selection of the editing section (Step S3).

  Next, when the overlapping section determination unit 120 receives a write instruction for writing the content of the editing section selected by the editing section selection unit 110 to the second recording medium 200 (step S4), the editing section selection unit 110 It is determined whether or not there is an overlapping section among the plurality of editing sections selected in (Step S5).

  When the overlapping section determination unit 120 determines that there is no overlapping section (step S5 / No), the writing unit 122 stores the contents of the editing section selected by the editing section selection unit 110 in the second recording medium 200. Write (step S6), and the process ends (End).

  When the overlapping section determination unit 120 determines that there is an overlapping section (step S5 / Yes), the editing section changing unit 121 selects the editing section selected by the editing section selection unit 110 so that there is no overlapping section. Is changed (step S7). For example, as shown in FIG. 3B, when an “overlapping section” exists in the editing section selected by the editing section selection means 110; A1 + A2, it is shown in FIGS. 3C and 3D. As described above, a part of the editing section is changed so that there is no overlapping section. FIG. 3 (c) shows the second editing section; A2 is changed to A'2, and the editing section selected by the editing section selection means 110; A1 + A2 has no overlapping section (A = A1 + A'2). FIG. 3D shows the first editing section; A1 is changed to A′1, and the editing section selected by the editing section selection means 110; A1 + A2 does not have an overlapping section (A = A'1 + A2).

  Next, the writing means 122 writes the contents of the editing section shown in FIG. 3C or FIG. 3D changed by the editing section changing means 121 to the second recording medium 200 (step S8), and performs processing. End (End).

<Operation / Effect of Editing Device 100 of this Embodiment>
As described above, the editing section selection unit 110 of the editing apparatus 100 according to the present embodiment selects the editing section of the content to be edited from the contents recorded on the first recording medium 21. Next, the overlapping section determination unit 120 determines whether or not there is an overlapping section where the editing sections overlap among the plurality of editing sections selected by the editing section selection unit 110. The editing section changing unit 121 selects the editing section selected by the editing section selecting unit 110 so that the overlapping section does not exist when there is an overlapping section among the plurality of editing sections selected by the editing section selecting unit 110. Change part of. The writing unit 122 writes the content of the editing section changed by the editing section changing unit 121 to the second recording medium 200.

  Thus, the editing apparatus 100 according to the present embodiment, when there is an overlapping section among the plurality of editing sections selected by the editing section selecting unit 110, reduces a part of the editing section so that the overlapping section does not exist. The content of the changed editing section is written to the second recording medium 200. As a result, the editing apparatus 100 according to the present embodiment performs control so that the content having the “overlapping section” as shown in FIG. 3B is not copied or moved to the second recording medium 200 of another system. Therefore, it is possible to avoid wastefully consuming the right of the number of times of copying the content, or failing to copy or move due to exceeding the allowable number of copies.

  In the processing operation shown in FIG. 2, the processing operation when the content recorded in the first recording medium 21 is edited and the edited content is written in the second recording medium 200 of another system has been described. However, the editing apparatus 100 according to the present embodiment edits the content recorded in the first recording medium 21 and stores the edited content in the memory in the same device 100 (the first recording medium 21 or the same device). The above-described processing operation shown in FIG. 2 can also be performed when writing to another recording medium or the like. As a result, even when the edited content is written in a memory (the first recording medium 21 or another recording medium in the same apparatus) in the same apparatus 100, the “overlapping section as shown in FIG. ”Can be controlled so as not to exist. For this reason, it is possible not to copy or move content having an “overlapping section” as shown in FIG. 3B to the second recording medium 200 of another system. It is possible to avoid that the right is wasted and the copy or move fails due to exceeding the allowable number of copies.

<Specific example of editing section change processing>
Next, a specific example of editing section change processing will be described with reference to FIG.

  For example, as shown in FIG. 4A, the editing section selection unit 110 selects editing sections; A1 to A4, and finishes selecting the editing section. In FIG. 4A, the first time selects the editing section; A1, the second time selects the editing section; A2, the third time selects the editing section; A3, and the fourth time the editing section; A4 is selected. Note that the edit section can be selected until a writing instruction is given. It is also possible to change or delete the editing section once selected.

  When the selection of the editing section is completed, the editing section selection means 110 arranges the editing sections; A1 to A4 shown in FIG. 4A in chronological order and changes them as shown in FIG. 4B. Edit section shown in FIG. 4 (a); A1 start time; T is T1, edit section; A2 start time; T is T2, edit section; A3 start time; T is T3 Yes, edit section; A4 start time; T is T4, so edit section shown in FIG. 4 (a); order of A1 to A4; A1 → A2 → A3 → A4 is shown in FIG. 4 (b) Change in order of A1 → A3 → A4 → A2.

  Since there are overlapping sections in the editing sections A1 to A4 shown in FIG. 4B, the overlapping section determination unit 120 includes the editing sections selected by the editing section selection means 110; the overlapping sections are included in the editing sections A1 to A4. The edit section changing means 121 determines that it exists, and changes the edit sections; A1 to A4 selected by the edit section selecting means 110, as shown in FIGS. 4 (c) to (e).

  In the first editing section changing process shown in FIG. 4 (c), the editing section; A3 is changed to A'3 so that there is no overlapping section in the editing section; A1 and the editing section; A3. Yes.

  In the editing process of the second editing section shown in FIG. 4D, the editing section is changed so that there is no overlapping section in the editing section changed in the first time; A1 + A'3 and the editing section; A4; A4 is changed to A'4.

  In the editing process of the third editing section shown in FIG. 4 (e), editing is performed so that there is no overlapping section in the editing section changed in the second time; A1 + A'3 + A'4 and editing section; A2. Section: A2 is deleted.

  When there are overlapping sections, the editing section changing means 121 edits the editing sections selected by the editing section selecting means 110; A1 to A4 as shown in FIGS. 4 (c) to 4 (e). It is possible to make sure that there are no overlapping sections in the editing sections A1 to A4 selected by the section selecting means 110.

  Next, the writing means 122 writes the content of the editing section shown in FIG. 4E; A1 + A′3 + A′4 to the second recording medium 200. As a result, the editing apparatus 100 according to the present embodiment can prevent the content having the “overlapping section” from being copied to the second recording medium 200 of another system. Can be avoided.

(Second Embodiment)
Next, a second embodiment will be described.

  In the first embodiment, a part of the editing section is changed so that there is no overlapping section among the plurality of editing sections selected by the editing section selection means 110.

  In the second embodiment, the editing section is changed so that there is no overlapping section less than a predetermined threshold among the plurality of editing sections selected by the editing section selection means 110. As a result, since it is possible to leave an overlapping section that is equal to or greater than a predetermined threshold, if the user intentionally creates an overlapping section that is equal to or greater than the predetermined threshold, the other system remains with the overlapping section remaining. The second recording medium 200 can be copied or moved. Hereinafter, the second embodiment will be described with reference to FIGS. 1, 5, and 6.

<Configuration of editing apparatus 100>
First, the configuration of the editing apparatus 100 according to the second embodiment will be described with reference to FIG.

  The editing apparatus 100 according to the present embodiment differs from the first embodiment in the processing performed by the overlapping section determination unit 120 and the editing section change unit 121.

  The overlapping section determination unit 120 of this embodiment determines whether or not there is an overlapping section less than a predetermined threshold among the plurality of editing sections selected by the editing section selection unit 110. The overlapping section determination unit 120 determines that the overlapping section less than the predetermined threshold is an overlapping section created by the user against the intention, and determines that the overlapping section greater than the predetermined threshold is the overlapping section created intentionally by the user. To do.

  Further, the editing section changing unit 121 changes a part of the editing section so that there is no overlapping section less than a predetermined threshold.

<Processing of editing apparatus 100>
Next, the processing operation of the editing apparatus 100 of this embodiment will be described with reference to FIG.

  As in the first embodiment, the editing section selection unit 110 starts selecting an editing section (step S1), and edits the content to be edited from the contents recorded on the first recording medium 21. Is selected (step S2), and the selection of the editing section is terminated (step S3).

  Next, when the overlapping section determination unit 120 receives a write instruction for writing the content of the editing section selected by the editing section selection unit 110 to the second recording medium 200 (step S4), the editing section selection unit 110 It is determined whether or not there is an overlapping section less than a predetermined threshold among the plurality of editing sections selected in (Step A1).

  When the overlapping section determination unit 120 determines that there is no overlapping section less than a predetermined threshold (step A1 / No), the writing unit 122 selects the content of the editing section selected by the editing section selection unit 110 as the second content. Is written into the recording medium 200 (step S6), and the process is terminated (End). For example, as shown in FIG. 6B, when “overlapping section; B” exists in the editing section selected by the editing section selecting means 110; A1 + A2, the “overlapping section; B” is predetermined. When the threshold is B1 or more (overlapping section; B ≧ predetermined threshold; B1), as shown in FIG. 6 (c), the selection is made by the editing section selection means 110 while the “overlapping section; The edited section; content of A1 + A2 is copied or moved to the second recording medium 200 of another system. Thus, when the user intentionally creates a predetermined threshold; B1 or more overlapping section; B, the duplicate section; B is left to be copied or moved to the second recording medium 200 of another system. It becomes possible to do.

  In addition, when the overlapping section determination unit 120 determines that there is an overlapping section that is less than the predetermined threshold (step A1 / Yes), the editing section changing unit 121 is configured so that there is no overlapping section that is less than the predetermined threshold. The editing section selected by the editing section selection means 110 is changed (step S7). For example, as shown in FIG. 6B, when “overlapping section; B” exists in the editing section selected by the editing section selecting means 110; A1 + A2, the “overlapping section; B” is predetermined. When the threshold value is less than B1 (overlapping section; B <predetermined threshold value; B1), as shown in FIG. 6 (d), the predetermined threshold value; the overlapping section less than B1; Change A1 + A2. FIG. 6 (d1) shows the second editing section; A2 is changed to A'2 and the editing section selected by the editing section selection means 110; A1 + A2 includes a predetermined threshold; an overlapping section less than B1; It does not exist (A = A1 + A'2). FIG. 6 (d2) shows the first editing section; A1 is changed to A'1 and the editing section selected by the editing section selection means 110; A1 + A2 includes a predetermined threshold; an overlapping section less than B1; It does not exist (A = A'1 + A2). As a result, if the user has created a predetermined threshold; an overlapping section less than B1; B unintentionally, it is possible to prevent the overlapping section; B from existing.

  Next, the writing unit 122 writes the content of the editing section shown in FIG. 6D changed by the editing section changing unit 121 to the second recording medium 200 (step S8), and ends the process (End). Thus, the content that contains the predetermined threshold; B that is less than B1; the content that exists in the second recording medium 200 of another system is prevented from being copied or moved. It becomes possible.

<Operation / Effect of Editing Device 100 of this Embodiment>
