Description

  The present invention relates to a moving image data editing device, a moving image data editing method, a playback device, a playback method, and a program.

  Patent Documents 1 and 2 disclose a technique for editing moving image data compressed by a long GOP (group of pictures) method. In this method, moving image data is compressed in GOP units. Each GOP may include an I frame, a B frame, and a P frame. Hereinafter, moving image data compressed by the method is referred to as compressed moving image data. Note that “editing moving image data” means removing a part of moving image data (the same applies hereinafter).

  When receiving an editing instruction for editing compressed moving image data at one or a plurality of editing points, the image encoding device described in Patent Document 1 decodes the compressed moving image data, and then stores predetermined data specified by the editing points. After the removed edited data is generated, the edited data is compressed again. In the process of recompressing the edited data, an inserted image composed of a predetermined image is inserted before and / or after the editing point in the edited data, and all the frames included in the edited data are edited. Recompression is performed so as to be the same as the frame type (I frame, B frame, P frame) in the previous data.

  The moving image editing apparatus described in Patent Literature 2 decodes compressed moving image data, generates edited data from which predetermined data is removed, and compresses the edited data again. In the editing process, when the middle point of the GOP is an editing point and the moving image data before the frame (B frame or P frame) located at the point is removed (edited), the edited data is recompressed. The frame in the GOP remaining after editing is recompressed as an I frame.

JP 2007-104182 A JP-A-8-205076

  There is a case where the same frame data is required to be identical between the compressed moving image data after editing and the compressed moving image data before editing.

  In the case of the technique described in Patent Document 1, at least a part of the moving image data of the frame included in the GOP to which the inserted image is added among the compressed moving image data after editing is the same as the moving image data before editing by compression. Sexuality is impaired. In the case of the technique described in Patent Document 2, the compressed moving image data after editing included in the GOP including the editing point, that is, compressed as B frame or P frame before editing, but after editing as I frame. The compressed moving image data of the frame loses its identity with the moving image data before editing.

  The present invention is an inter-frame compression technique or an inter-frame prediction technique, particularly a technique for editing compressed moving picture data compressed by the Long GOP method, and includes between edited compressed moving picture data and pre-edited compressed moving picture data. Therefore, an object of the present invention is to provide an editing technique that ensures the identity of the data of the corresponding frame.

It will be understood by those skilled in the art that there are various modifications to the implementation method and apparatus.

  In addition, the functional block diagram used in the description of the present embodiment shows a functional unit block, not a hardware unit configuration. In these drawings, each device is described as being realized by one device, but the means for realizing it is not limited to this. That is, it may be a physically separated configuration or a logically separated configuration.

<First Embodiment>
First, the outline of the moving image data editing apparatus of the present embodiment will be described with reference to FIG. The moving image data editing apparatus of the present embodiment edits compressed editing target moving image data. In the present embodiment, a case of the Long GOP method, which is an embodiment using an inter-frame compression technique or an inter-frame prediction technique as a compression method, will be described. FIG. 1 schematically shows a plurality of frames included in editing target moving image data. The plurality of frames are arranged in a line along the time axis in the order in which they are output during reproduction. Here, “reproduction” means normal reproduction in which images are output in the order normally assumed, and is not reproduction such as so-called reverse reproduction (the same applies hereinafter). In the figure, each frame indicates the type of an I frame (Intra-coded Frame), a B frame (Bi-directional Predicted Frame), and a P frame (Predicted Frame). An I frame is a frame that is encoded without using inter-frame prediction. A B frame is a frame that is encoded using any one of forward prediction, backward prediction, and bidirectional prediction (interframe prediction). A P frame is a frame that is encoded using forward prediction (interframe prediction).

  The moving image data editing apparatus accepts an input from the user for designating a desired extraction start position. For example, an input for designating a desired extraction start position may be accepted according to the elapsed time from the beginning of the editing target video data, or a predetermined frame included in the editing target video data is specified as a desired extraction start position You may accept input to do. In the case of FIG. 1, the third frame (B frame) from the left end in the drawing is designated as the desired cutout start position.

  When the moving image data editing apparatus receives an input designating a desired extraction start position, it determines whether or not the frame corresponding to that position is an I frame. When the frame is not an I frame (B frame in the case of FIG. 1), the moving image data editing apparatus determines an I frame located before the frame as the extraction start position. Note that the frame positioned before the first frame means a frame that is output before the first frame when moving image data is reproduced (the same applies hereinafter). In the case of FIG. 1, the I frame located two frames before the B frame (third frame from the left end in the figure) designated as the desired cut start position is determined as the cut start position.

  After that, the moving image data editing apparatus, for example, after decoding the editing target moving image data, removes moving image data (frames) positioned temporally before the extraction start position (does not remove the I frame at the extraction start position). . Next, the moving image data editing apparatus compresses the moving image data in the same manner as the editing target moving image data, and generates edited moving image data.

  In addition, the moving image data editing device generates first information (eg, the number of difference frames between the extraction start position and the desired extraction start position) that is information for specifying the desired extraction start position from the extraction start position. And associate with the edited video data.

  In the case of such editing means, the first frame of the edited moving image data is an I frame. When such edited moving image data is compressed in the same manner as the editing target moving image data, the composition of each frame (I frame, B frame, P frame) is compressed to be the same as the composition before editing. The Also, moving image data that was not included before editing is not newly included after editing. Further, in the case of such editing means, the edited moving image data can be directly cut out from the editing target moving image data file without being decompressed or compressed. For this reason, the identity of the data of a corresponding frame is ensured between the compressed moving image data after editing and the compressed moving image data before editing.

  Further, according to the present embodiment, it is possible to specify the desired extraction start position specified by the user using the first information. For this reason, for example, reproduction from a desired cutting start position can be realized.

  Hereinafter, the configuration of the moving image data editing apparatus of the present embodiment will be described in detail.

  FIG. 2 shows an example of a functional block diagram of the moving image data editing apparatus 10. As illustrated, the moving image data editing apparatus 10 includes a data acquisition unit 11, an input reception unit 12, a cutout position determination unit 13, a removal unit 14, and a desired cutout position specifying information generation unit 15. . Hereinafter, each part will be described.

  The data acquisition unit 11 acquires editing target moving image data (compressed moving image data) compressed by the Long GOP method input by the user. The data acquisition unit 11 may acquire a moving image file including editing target moving image data. In addition to the editing target moving image data, the moving image file may include a frame rate, information related to compression (the number of frames included in one GOP, and the like).

  The input receiving unit 12 receives an input for designating a desired extraction start position of the editing target moving image data. For example, the input receiving unit 12 may receive an input for designating a desired clipping start position based on an elapsed time from the beginning of the editing target moving image data, or a predetermined frame included in the editing target moving image data. You may receive the input designated as a desired cutting start position. In the former case, the input receiving unit 12 may receive an input of a numerical value (elapsed time from the beginning), for example. In the latter case, the input receiving unit 12 decodes, for example, editing target moving image data and outputs an image on the display. Then, a determination input that is received in a state where an image of a predetermined frame is displayed on the display may be received as an input that uses the frame as a desired extraction start position.

  If the desired cut start position is not an I frame, the cut position determination unit 13 determines an I frame that is located temporally before the desired cut start position as the cut start position.

  In order to execute such processing, the cut-out position determination unit 13 first specifies a frame corresponding to the desired cut-out start position based on the input content received by the input reception unit 12, and then specifies the specified frame. It is determined whether the frame is an I frame. Means for realizing the processing is not particularly limited, and any conventional technique can be adopted. An example will be described below.

  An example of means for specifying a frame corresponding to the desired cutout start position will be described. For example, when the input receiving unit 12 receives an input of the elapsed time from the beginning of the editing target moving image data as information for designating the desired cutout start position, the cutout position determining unit 13 sets the frame rate to a predetermined frame rate. Based on this, it is possible to identify the frame corresponding to the desired cutout start position. In addition, when the input receiving unit 12 receives an input for designating a predetermined frame as information for designating the desired cutout start position, the cutout position determining unit 13 recognizes the frame so that the desired cutout start position is recognized. Can be identified.

  An example of means for determining the frame type will be described. For example, a means for determining the frame type of each frame using a table describing the frame type of each frame described in JP 2010-28435 A may be used. Alternatively, the frame type discriminating means using the difference in information amount between the I frame, the B frame, and the P frame described in JP 2007-82156 A and JP 2009-273010 A may be used. Good.

  If the determination result of determining whether or not the frame corresponding to the desired cut start position is an I frame is “No”, the cut position determination unit 13 is positioned before the desired cut start position. The I frame to be determined is determined as the extraction start position.

  When there are a plurality of I frames positioned in front of time, any I frame may be set as the extraction start position. Among the plurality of I frames, the I frame whose temporal distance is closest to the desired extraction start position (the I frame having the smallest number of difference frames from the frame corresponding to the desired extraction start position) is used as the extraction start position. It may be determined. In this way, the information amount of the edited moving image data can be reduced.

  A means for specifying such an I frame is not particularly limited, and any conventional technique can be adopted. For example, the I frame may be specified by determining the type of each frame while tracing back the time axis (time axis in the case of reproduction) from the frame corresponding to the desired extraction start position. Alternatively, the I frame may be specified using a table described in Japanese Patent Application Laid-Open No. 2010-28435.

  The removing unit 14 removes the moving image data positioned before the cut start position from the editing target moving image data, and generates edited moving image data. That is, the removal unit 14 removes the data of the frame located temporally before the I frame corresponding to the cutout start position from the editing target moving image data, and generates the edited moving image data. Note that the removing unit 14 does not remove the I frame corresponding to the extraction start position. For example, the removing unit 14 decodes the editing target moving image data and removes predetermined moving image data in this state. In such a case, the removal unit 14 compresses the moving image data after removing the predetermined moving image data by the same method as the editing target moving image data, and obtains the edited moving image data. In addition, the removal unit 14 removes the data of the frame located before the I frame corresponding to the extraction start position from the editing target moving image data without decoding the editing target moving image data, and after editing Video data may be generated. That is, the edited moving image data may be moving image data directly cut out from the editing target moving image data file without being decompressed or compressed. In any case, the edited moving image data is compressed moving image data.

  The desired cut position specifying information generating unit 15 generates first information that is information for specifying the desired cut start position from the cut start position, and associates the first information with the edited moving image data. The first information is not particularly limited as long as the desired cut start position can be specified from the cut start position. For example, the first information may be the number of difference frames between the I frame corresponding to the extraction start position and the frame corresponding to the desired extraction start position, or these frames when the moving image is reproduced. It may be a time difference between. The means for generating such first information is not particularly limited. For example, when the cutting position determination unit 13 determines the cutting start position, the first information is obtained by counting the number of frames that go back from the frame corresponding to the desired cutting start position to the I frame that is the cutting start position. May be generated, or the first information may be generated using a table described in Japanese Patent Laid-Open No. 2010-28435.

  The desired cut-out position specifying information generation unit 15 may store the generated first information in, for example, a moving image file including edited moving image data.

  Next, an example of the processing flow of the moving image data editing method of this embodiment will be described using the flowchart of FIG.

  First, the data acquisition unit 11 acquires editing target moving image data compressed by the Long GOP method input by the user (S10).

  Thereafter, the input receiving unit 12 receives a user input for designating a desired clipping start position of the editing target moving image data (S11).

  Next, the cutout position determination unit 13 specifies a frame corresponding to the desired cutout start position based on the input content received by the input reception unit 12 in S11, and then whether or not the specified frame is an I frame. Determine. Then, when the desired cut start position is not an I frame, the cut position determination unit 13 determines an I frame located before the desired cut start position as the cut start position (S12).

  Next, the edited moving image data (compressed moving image data) obtained by removing the moving image data positioned before the extraction start position determined in S12 from the editing target moving image data acquired in S10 is removed by the removing unit 14. Generate (S13).

  Next, the desired cut position specifying information generating unit 15 generates first information that is information for specifying the desired cut start position from the cut start position (S14), and after editing the generated first information Corresponding to the video data (S15).

  Note that the edited moving image data generated in S13 is stored in a predetermined storage device or output to an external device.

  The moving image data editing apparatus according to the present embodiment removes moving image data (frames) in units of GOPs. In such a case, the first frame of edited moving image data after editing is always an I frame. For this reason, even if the video data after editing processing is compressed in the same manner as the video data to be edited when the processing (editing processing) for removing some data after decoding the video data to be edited is performed, each frame Are compressed so that their types (I frame, B frame, P frame) are the same as those before editing. For this reason, the identity of the corresponding frame data is ensured between the edited moving image data (compressed moving image data) and the editing target moving image data (compressed moving image data). Further, since moving image data (frames) are removed in GOP units, it is possible to remove some data without decoding the editing target moving image data. Similarly, in this case, the same frame data is ensured between the edited moving image data (compressed moving image data) and the editing target moving image data (compressed moving image data).

  Further, according to the present embodiment, the edited first moving image data is associated with the first information that is information for specifying the desired cut start position from the cut start position. For this reason, using the first information, it is possible to specify the desired clipping start position designated by the user. As a result, for example, reproduction from a desired cutting start position can be realized.

<Second Embodiment>
The moving image data editing apparatus according to the present embodiment is different from the first embodiment in that the processing when the desired extraction start position is an I frame is specified. Hereinafter, only the configuration different from the first embodiment will be described, and the description of the configuration common to the first embodiment will be omitted.

  When the desired cut start position is an I frame, the cut position determination unit 13 determines the I frame as the cut start position.

  The desired cut position specifying information generating unit 15 generates information indicating that the cut start position is the desired cut start position as the first information. For example, the desired cut position specifying information generating unit 15 determines that the number of difference frames between the I frame corresponding to the cut start position and the frame corresponding to the desired cut start position is “0 (zero)”. Information to be shown may be generated. Alternatively, the desired cutout position specifying information generation unit 15 may generate information indicating that the time difference between these frames when a moving image is reproduced is “0 (zero)”.

  According to the present embodiment, it is possible to achieve the same effects as those of the first embodiment.

<Third Embodiment>
First, an outline of the moving image data editing apparatus according to the present embodiment will be described with reference to FIG. The moving image data editing apparatus of this embodiment edits editing target moving image data compressed by the Long GOP method. FIG. 4 schematically shows a plurality of frames included in the editing target moving image data. The plurality of frames are arranged in a line along the time axis in the order in which they are output during reproduction. In the figure, each frame indicates the type of I frame, B frame, and P frame.

  The moving image data editing apparatus receives an input for designating a desired cutout end position from the user. For example, an input for designating a desired cutout end position may be accepted based on the elapsed time from the beginning of the editing target moving image data. Alternatively, the moving image data editing apparatus may accept an input designating a predetermined frame included in the editing target moving image data as a desired cutout end position. In the case of FIG. 4, the third frame (B frame) from the right end in the figure is designated as the desired cut-out end position.

  When the moving image data editing apparatus receives an input designating a desired cutout end position, it determines whether or not the frame corresponding to the position is an I frame. When the frame is not an I frame (B frame in the case of FIG. 4), the moving image data editing apparatus determines an I frame positioned later in time as the cut-out end position. Note that the frame positioned after the first frame means a frame output after the first frame when moving image data is reproduced (the same applies hereinafter). In the case of FIG. 4, the I frame located two frames after the B frame (third frame from the right end in the figure) designated as the desired cutout end position is determined as the cutout end position.

  Thereafter, the moving image data editing apparatus, for example, after decoding the editing object moving image data, removes moving image data (frames) positioned later in time than the cutout end position (does not remove the I frame at the cutout end position). Next, the moving image data editing apparatus compresses the moving image data in the same manner as the editing target moving image data, and generates edited moving image data.

  In addition, the moving image data editing device generates second information (eg, the number of difference frames between the cutout end position and the desired cutout end position) that is information for specifying the desired cutout end position from the cutout end position. And associate with the edited video data.

  In the case of such editing means, the last frame of the edited moving image data is an I frame. When such edited moving image data is compressed in the same manner as the editing target moving image data, each frame type (I frame, B frame, P frame) is compressed so as to be the same as the type before editing. The For this reason, the identity of the data of a corresponding frame is ensured between the compressed moving image data after editing and the compressed moving image data before editing.

  Further, according to the present embodiment, the desired cutout end position specified by the user can be specified using the second information. Therefore, for example, reproduction up to the desired cutout end position can be realized.

  Hereinafter, the configuration of the moving image data editing apparatus of the present embodiment will be described in detail.

  An example of a functional block diagram of the moving image data editing apparatus 10 of the present embodiment is shown in FIG. 2 as in the first embodiment. As illustrated, the moving image data editing apparatus 10 includes a data acquisition unit 11, an input reception unit 12, a cutout position determination unit 13, a removal unit 14, and a desired cutout position specifying information generation unit 15. . Hereinafter, each part will be described. Since the configuration of the data acquisition unit 11 is the same as that of the first embodiment, the description thereof is omitted here.

  The input receiving unit 12 receives an input for designating a desired extraction end position of the editing target moving image data. For example, the input receiving unit 12 may receive an input for designating a desired clipping end position based on an elapsed time from the beginning of the editing target moving image data, or a predetermined frame included in the editing target moving image data. You may receive the input designated as a desired cutting end position. In the former case, the input receiving unit 12 may receive an input of a numerical value (elapsed time from the beginning), for example. In the latter case, the input receiving unit 12 decodes, for example, editing target moving image data and outputs an image on the display. Then, a determination input that is received in a state where an image of a predetermined frame is displayed on the display may be received as an input having the frame as a desired cut-out end position.

  If the desired cutout end position is not an I frame, the cutout position determination unit 13 determines an I frame located after the desired cutout end position as the cutout end position.

  In order to execute such processing, the cut-out position determination unit 13 first specifies a frame corresponding to the desired cut-out end position based on the input content received by the input reception unit 12, and then specifies the specified frame. It is determined whether the frame is an I frame. Since the means for realizing these processes is as described in the first embodiment, the description thereof is omitted here.

  If the determination result of determining whether or not the frame corresponding to the desired cutout end position is an I frame is “No”, the cutout position determination unit 13 is positioned later in time than the desired cutout end position. The I frame is determined as the cutting end position.

  When there are a plurality of I frames located later in time, any I frame may be set as the cutout end position. Among the plurality of I frames, the I frame whose temporal distance is closest to the desired extraction end position (the I frame having the smallest number of difference frames from the frame corresponding to the desired extraction end position) is set as the extraction end position. It may be determined. In this way, the information amount of the edited moving image data can be reduced.

  A means for specifying such an I frame is not particularly limited, and any conventional technique can be adopted. For example, the I frame may be specified by determining the type of each frame along the time axis (the time axis in the case of reproduction) in order from the frame corresponding to the desired cutout end position. Alternatively, the I frame may be specified using a table described in Japanese Patent Application Laid-Open No. 2010-28435.

  The removal unit 14 removes the moving image data positioned later in time from the cutout end position from the editing target moving image data, and generates edited moving image data. That is, the removal unit 14 removes the data of the frame located after the I frame corresponding to the cutout end position from the editing target moving image data, and generates the edited moving image data. Note that the removal unit 14 does not remove the I frame corresponding to the cutout end position. For example, the removing unit 14 decodes the editing target moving image data and removes predetermined moving image data in this state. In such a case, the removal unit 14 compresses the moving image data after removing the predetermined moving image data by the same method as the editing target moving image data, and obtains the edited moving image data. That is, the edited moving image data is compressed moving image data.

  The desired cutout position specifying information generating unit 15 generates second information that is information for specifying the desired cutout end position from the cutout end position, and associates it with the edited moving image data. The second information is not particularly limited as long as the desired cutting end position can be specified from the cutting end position. For example, the second information may be the number of difference frames between the I frame corresponding to the cutout end position and the frame corresponding to the desired cutout end position, or these frames when the moving image is reproduced. It may be a time difference between. The means for generating such second information is not particularly limited. For example, when the cut position determining unit 13 determines the cut end position, the number of frames that have passed from the frame corresponding to the desired cut end position to the I frame that is the cut end position is counted. Second information may be generated. Or 2nd information may be produced | generated using the table described in Unexamined-Japanese-Patent No. 2010-28435.

  The desired cut position specifying information generation unit 15 may store the generated second information in, for example, a moving image file including edited moving image data.

  Next, an example of the processing flow of the moving image data editing method of the present embodiment will be described using the flowchart of FIG.

  First, the data acquisition unit 11 acquires edit target moving image data compressed by the Long GOP method input by the user (S20).

  Thereafter, the input receiving unit 12 receives a user input for designating a desired cutout end position of the editing target moving image data (S21).

  Next, the cutting position determination unit 13 specifies a frame corresponding to the desired cutting end position based on the input content received by the input receiving unit 12 in S21, and then whether or not the specified frame is an I frame. Determine. Then, when the desired cutout end position is not an I frame, the cutout position determination unit 13 determines an I frame located after the desired cutout end position as the cutout end position (S22).

  Next, the removal unit 14 generates edited moving image data (compressed moving image data) in which the moving image data positioned after the cut end position determined in S22 is removed from the editing target moving image data acquired in S20. (S23).

  Next, the desired cut position specifying information generating unit 15 generates second information that is information for specifying the desired cut end position from the cut end position (S24), and editing the generated second information Corresponding to moving image data (S25).

  Note that the edited moving image data generated in S23 is stored in a predetermined storage device or output to an external device.

  The moving image data editing apparatus according to the present embodiment removes moving image data (frames) in units of GOPs. For this reason, the final frame of the edited moving image data after editing is always an I frame. When such moving image data is compressed in the same manner as the editing target moving image data, the type of each frame (I frame, B frame, P frame) is compressed to be the same as the type before editing. For this reason, the identity of the corresponding frame data is ensured between the edited moving image data (compressed moving image data) and the editing target moving image data (compressed moving image data).

  Further, according to the present embodiment, the edited second moving image data is associated with the second information that is information for specifying the desired cutout end position from the cutout end position. For this reason, the desired cutting end position specified by the user can be specified using the second information. As a result, for example, reproduction up to the desired cutting end position can be realized.

<Fourth Embodiment>
The moving image data editing apparatus according to the present embodiment is different from the third embodiment in that the processing when the desired cutout end position is an I frame is specified. Hereinafter, only the configuration different from the third embodiment will be described, and the description of the configuration common to the third embodiment will be omitted.

  When the desired cutout end position is an I frame, the cutout position determination unit 13 determines the I frame as the cutout end position.

  The desired cut position specifying information generating unit 15 generates information indicating that the cut end position is the desired cut end position as the second information. For example, the desired cut position specifying information generating unit 15 determines that the number of difference frames between the I frame corresponding to the cut end position and the frame corresponding to the desired cut end position is “0 (zero)”. Information indicating that the time difference between the frames when the moving image is reproduced is “0 (zero)” may be generated.

  According to the present embodiment, it is possible to achieve the same effects as those of the third embodiment.

<Fifth Embodiment>
First, the outline of the moving image data editing apparatus of the present embodiment will be described with reference to FIG. The moving image data editing apparatus of this embodiment edits editing target moving image data compressed by the Long GOP method. FIG. 6 schematically shows a plurality of frames included in the editing target moving image data. The plurality of frames are arranged in a line along the time axis in the order in which they are output during reproduction. In the figure, each frame indicates the type of I frame, B frame, and P frame.

  The moving image data editing apparatus accepts an input specifying a desired cut start position and a desired cut start position from the user. For example, the moving image data editing apparatus may accept an input for designating each of a desired cutout start position and a desired cutout end position according to the elapsed time from the beginning of the editing target moving image data. Alternatively, the moving image data editing apparatus may accept an input for designating a predetermined frame included in the editing target moving image data for each desired clipping start position and each desired clipping end position. In the case of FIG. 6, the third frame (B frame) from the left end in the figure is designated as the desired cutout start position, and the third frame (B frame) from the right end in the figure is designated as the desired cutout end position. .

  When the moving image data editing apparatus receives an input designating a desired cutout start position and a desired cutout end position, it determines whether or not the frame corresponding to the position is an I frame. When the frame is not an I frame (in the case of FIG. 6, all are B frames), the moving image data editing apparatus extracts the I frame in the same manner as the processing described in the first to fourth embodiments. It is determined as the cutting end position. In the case of FIG. 6, the I frame located two frames before the B frame (third frame from the left end in the figure) designated as the desired cut start position is determined as the cut start position. In addition, an I frame that is located after the B frame (third frame from the left end in the figure) designated as the desired cutout end position is determined as the cutout end position.

  Thereafter, the moving image data editing device is positioned after the decoding end position, for example, after the decoding of the editing target moving image data, the moving image data (frame) positioned before the extraction start position and the extraction end position. The moving image data (frame) is removed (the I frame at the cut start position and the I frame at the cut end position are not removed). Next, the moving image data editing apparatus compresses the moving image data in the same manner as the editing target moving image data, and generates edited moving image data.

  In addition, the moving image data editing device includes first information that is information for specifying a desired cut start position from the cut start position (eg, the number of difference frames between the cut start position and the desired cut start position), and Second information (eg, the number of difference frames between the cutout end position and the desired cutout end position) that is information for specifying the desired cutout end position from the cutout end position is generated, and the edited video data Associate.

  According to such a moving image data editing apparatus of the present embodiment, the same operational effects as those of the first to fourth embodiments can be realized.

  Note that the configuration of the moving image data editing apparatus of this embodiment can be realized by arbitrarily combining the configurations described in the first to fourth embodiments. Therefore, the description here is omitted.

  Thereafter, the input receiving unit 12 receives a user input designating each of the desired extraction start position and the desired extraction end position of the editing target moving image data (S31, S32).

  Next, the cutout position determination unit 13 identifies the frame corresponding to the desired cutout start position and the frame corresponding to the desired cutout end position based on the input contents received by the input receiving unit 12 in S31 and S32. Then, it is determined whether or not the identified frame is an I frame.

  If the desired cut start position is not an I frame, the cut position determination unit 13 determines an I frame located before the desired cut start position as the cut start position (S33). On the other hand, when the desired cut start position is the I frame, the cut position determination unit 13 determines the desired cut start position as the cut start position.

  If the desired cutout end position is not an I frame, the cutout position determination unit 13 determines an I frame located later in time than the desired cutout end position as the cutout end position (S34). On the other hand, when the desired cutout end position is an I frame, the cutout position determination unit 13 determines the desired cutout end position as the cutout end position.

  Next, from the editing target moving image data acquired in S30, the removal unit 14 acquires the moving image data positioned before the cutting start position and moving image data positioned after the cutting end position. The removed edited moving image data (compressed moving image data) is generated (S35).

  Next, the desired cut position specifying information generating unit 15 specifies first information that is information for specifying the desired cut start position from the cut start position, and the desired cut end position from the cut end position. Second information, which is information, is generated (S36, S37). The desired cut position specifying information generating unit 15 associates the generated first information and second information with the edited moving image data (S38).

  Note that the edited moving image data generated in S13 is stored in a predetermined storage device or output to an external device.

<Tenth Embodiment>
In the present embodiment, an application example of the above-described moving image data editing apparatus 10 will be described.

  FIG. 12 shows an overall image of this embodiment. In this embodiment, CM (Commercial Message) moving image data produced by production companies such as production company A 200A and production company B 200B is carried into broadcast stations such as broadcast station A 300A and broadcast station B 300B via center system 100. In the system, the moving image data editing apparatus 10 is used. The production company delivers the compressed video data compressed by the Long GOP method to the broadcasting station.

  In recent years, techniques for managing CM moving image data are shifting from tape to file base. As means for bringing file-based data into a broadcasting station, means using a network such as the Internet, means via a portable storage device, and the like are conceivable. According to such a system, various advantages can be obtained.

  For example, when CM moving image data is carried into a broadcasting station using a tape medium, each broadcasting station converts the data into a predetermined data format (such as XDCAM, P2, and GFPAK), and then stores and broadcasts the data. Since the identity of the data is lost by the conversion of the data format, each broadcasting station carefully checks the quality of the converted data before broadcasting. There is a case where video data of a certain CM produced by a certain production company is carried into a plurality of broadcasting stations. In such a case, each of the plurality of broadcasting stations performs conversion and quality check of the video data of this one CM. Is inefficient.

  On the other hand, when CM video data is carried into a broadcast station using file-based data, each broadcast station does not need to convert the data format, so the data at the time of carry-in and the data at the time of broadcast are ensured to be identical. It becomes possible to do. For this reason, if the production company carefully checks the quality before carrying it in to the broadcasting station and carries in the broadcasting station what has no problem, the quality check in each of the plurality of broadcasting stations can be reduced. As described above, the file-based management can improve the efficiency of the entire system as compared with the management using the tape medium.

  However, even if CM video data is imported to a broadcasting station as file-based data, the imported video data is not stored as it is, but is broadcast using it. There is a possibility that the latter data is used for broadcasting.

  When the CM is carried in, the moving image data is preferably configured as shown in FIG. That is, it is desirable for the production company to produce and carry in moving image data having a configuration as shown in FIG. The moving image data shown in FIG. 13 has a configuration in which attached information (black signal, color bar, credit, first cut, last cut, etc.) is attached before and after the main part of the CM (content main part). Of these, only the main part of the CM is actually broadcast. For this reason, the broadcasting station into which the CM moving image data has been imported can store the edited moving image data after performing editing to remove some of the attached information located before and after the CM main part. This is preferable because the volume of data to be saved can be reduced.

  However, if the identity of the corresponding frame data is lost between the compressed video data after editing and the compressed video data before editing, each broadcast station carefully checks the quality of the edited data. Necessity comes out.

  Therefore, each broadcasting station of the present embodiment edits the moving image data of the CM that has been loaded, using the moving image data editing apparatus 10 of the present embodiment described above.

  That is, as shown in FIG. 12, CM moving image data produced by a production company such as production company A 200A, production company B 200B, etc., is carried into the submission server 103 of the center system 100. Then, the CM moving image data is carried from the submission server 103 of the center system 100 to the submission server 301A of the broadcasting station A 300A, the submission server 301B of the broadcasting station B 300B, and the like.

  CM moving image data carried into the submission server 301A of the broadcasting station A 300A and the submission server 301B of the broadcasting station B 300B is acquired by the data acquisition unit 11 of the moving image data editing apparatus 10 as editing target moving image data. Thereafter, after the predetermined processing as described above is performed in the moving image data editing apparatus 10, the edited moving image data associated with the first information and / or the second information is sent to the sending servers 302A and 302B. Sent and stored on the server.

  As described in the above embodiment, according to the moving image data editing apparatus 10 of the present embodiment, the same frame data is ensured between the compressed moving image data after editing and the compressed moving image data before editing. Is done.

  Although not shown, each broadcasting station includes the playback device 20 of the present embodiment, and can use the playback device 20 to play back the edited moving image data during broadcasting. As described in the above embodiment, according to the playback device 20 of the present embodiment, when editing the editing target moving image data, playback is performed from the position specified by the user and / or playback is performed up to the position specified by the user. Processing can be realized.

  In addition, as a modification of this embodiment, it can be set as a structure as shown in FIG. In the configuration shown in FIG. 14, the center system 100 includes the moving image data editing device 10. The center system 100 uses the moving image data editing device 10 to edit the moving image data of the CM that has been transferred from the production company to the center submission server 101. Then, the edited CM moving image data (edited moving image data) is carried into each broadcasting station via the center sending server 102. Although not shown, each broadcasting station includes the playback device 20 of the present embodiment, and can use the playback device 20 to play back the edited CM video data (edited video data) during broadcasting. .
