Description

  The present invention relates to an information processing apparatus, and more particularly to an information processing apparatus that edits data stored in a file.

  A technique using an MXF (Material Exchange Format) file that stores metadata or the like in files such as video data and audio data is known (see, for example, Patent Document 1). For example, as shown in FIG. 1, an MXF file is composed of a header (Header Partition), a body (Body Partition), and a footer (Footer Partition), and metadata is stored in the header, and video data and audio are stored in the body. Stores actual data such as data.

  Each of the above-mentioned data stored in the MXF file is represented by a KLV (Key-Length-Value) structure. Specifically, the KLV structure is represented by actual data (Value), data length (Length) of the actual data, and identification information (for example, identification tag) (Key) that identifies the type of the actual data. .

Specifically, the editing device imports the replacement source and replacement destination MXF files, converts them into video data, performs replacement processing based on the converted video data, and newly adds the replacement based on the replaced video data. MXF file was generated (exported).

  However, in the above-described data replacement process in the MXF file, it is necessary to import and export the MXF file, and there is a problem that the replacement process takes time.

<First Embodiment>
First, in order to facilitate understanding of the embodiment of the present invention, the data structure of the MXF file related to the present invention will be described. As shown in FIG. 1, the MXF file is composed of three partitions, a header part (header), a body partition (body), and a footer partition (footer). The header includes Header Partition Pack, which is the start code of the first partition of the MXF file, and Header Metadata that stores metadata required in the MXF file. Further, the header optionally has an Index Table and Essence. The body has Body Partition Pack, which is the start code of the partition of the body. Arbitrary header metadata and index table, and Essence to store contents (actual data such as video data and audio data) stored in MXF file Have The footer has a Footer Partition Pack that is the start code of the last partition of the MXF file, and optionally has Header Metadata, Index Table, and Random Index Pack.

  As shown in FIG. 2, Header Metadata includes Primer and a plurality of metadata (metadata). The metadata includes, for example, structure metadata and description metadata. The structural metadata is metadata for storing technical data such as the internal structure of the MXF file and the format of video (Video) data and audio (Audio) data stored in Essence. Only one structure metadata can be stored in the MXF file. The description metadata is metadata indicating the content of the content video such as the content title and keywords.

  As shown in FIG. 1, each data stored in the MXF file includes actual data (Value), a data length (Length) of the actual data, and identification information (Key) for identifying the type of the actual data. And a KLV structure represented by a structure in which these are associated with each other (hereinafter, data having the KLV structure is described as KLV data (data of a predetermined unit)). That is, the MXF file includes a plurality of KLV data. FIG. 3 is a diagram illustrating an example of KLV data. “Key” is 16-byte data conforming to SMPTE (Society of Motion Picture and Television Engineers) 377M. “Length” is 4-byte data indicating the data length of the actual data stored in Value. “Value” is actual data such as video data, audio data, video data, or metadata related to audio data. In the MXF file, the type of actual data included in Value can be specified by detecting Key and referring to a table or the like that describes the correspondence between Key and Value type.

  Next, a first embodiment of the present invention will be described with reference to FIGS. 4 to 11 are diagrams for explaining the configuration of the information processing apparatus according to the first embodiment. 12 to 14 are diagrams for explaining the operation of the information processing apparatus.

[Constitution]
FIG. 4 is a block diagram showing the configuration of the information processing apparatus 1 according to the first embodiment of the present invention. As illustrated in FIG. 4, the information processing apparatus 1 includes a calculation unit 11, a memory 12, an input unit 13, an output unit 14, and a storage unit 15. The information processing apparatus 1 uses the video data and / or audio data stored in the replacement MXF file (replacement source file) and the video data and / or audio data stored in the replacement MXF file (replacement destination file). Copying (duplicating) the audio data and replacing the video data and / or audio data.

  The calculation unit 11 is configured by, for example, a CPU (Central Processing Unit). The calculation unit 11 reads a program stored in advance in the storage unit 15 and executes the program to thereby obtain an input reception unit 21 (input reception unit), an analysis unit 22 (analysis unit), and a replacement unit 23 (replacement). Means). Below, each function of the calculating part 11 is demonstrated.

  First, the input receiving unit 21 receives input of a replacement source file and a replacement destination file via the input unit 13. The input receiving unit 21 may receive an input of a replacement source file and a replacement destination file from a storage device such as the storage unit 15 or a replacement source file transmitted via a network (not shown) or the like. An input with a replacement destination file may be accepted. Here, as illustrated in FIG. 5, it is assumed that the input receiving unit 21 receives input of a replacement source file 31 of 30 frames (for example, 1 second) and a replacement destination file of 300 frames (for example, 10 seconds). It is assumed that the video data codec of the replacement source file and the replacement destination file is “AVC-Intra 100 Mbps”, and the audio data codec is “8ch 16 bits”.

  Subsequently, the input receiving unit 21 receives input of replacement information. The replacement information includes, for example, the replacement target range (replacement source range) of the replacement source file, the replacement target range (replacement destination range) of the replacement destination file, and the type of replacement target data (replacement target type information). Information. The replacement target range is specified by, for example, a time code (hour: minute: second: frame) indicating a replacement start position and a replacement size. The type of data to be replaced is, for example, video data, audio data, both video data and audio data, and the like. In addition, when audio data is included in the type of data to be replaced, the input receiving unit 21 can receive an input of a channel number (identification information) of audio data to be replaced. Here, the area from the first frame (0 frame) to 29 frames of the replacement source file is specified as the replacement target range of the replacement source file 31, and the replacement target range of the replacement destination file 32 is from 150 frames to 179 frames. Suppose you specify a region. Also, assume that video data is acquired as the type of data to be replaced.

  Next, the analysis unit 22 acquires metadata. For example, the analysis unit 22 acquires (extracts) the metadata stored in the Header Partition of the replacement source file 31 and the metadata stored in the Header Partition of the replacement destination file 32 in accordance with the MXF file standard SMPTE377M. Subsequently, the analysis unit 22 determines whether or not the replacement target range of the replacement source file included in the replacement information that has received the input exists in the replacement source file and the replacement destination file. For example, when the type of data to be replaced includes video data, the analysis unit 22 acquires video codec information (for example, AVC-Intra) of the replacement source file and the replacement destination file from the metadata, and acquires the acquired video It is determined whether the codec information matches. Further, for example, when the type of data to be replaced includes audio data, the analysis unit 22 analyzes audio codec information (for example, PCM (Pulse Code Modulation) (non-PCM)) of the replacement source file and the replacement destination file. Compression) format) is acquired as metadata, and it is determined whether the acquired audio codec information matches. That is, the analysis unit 22 acquires “Key” included in the KLV data stored in the replacement source range and the replacement destination range, respectively, and determines whether or not “Key” matches. Thereby, the analysis unit 22 determines whether the replacement source file 31 and the replacement destination file 32 can be replaced.

  In the example of FIG. 5, the replacement target range (0 to 29 frames) of the replacement source file 31 and the replacement target range (150 to 179 frames) of the replacement destination file 32 exist. Further, it is assumed that the video codec and audio codec of the replacement source file and the replacement destination file are the same. Therefore, the analysis unit 22 determines that replacement is possible.

  When it is determined that the replacement is possible (that is, when “Key (actual data type)” matches), the replacement unit 23 stores the KLV data stored in the replacement destination range in the replacement source range. Perform replacement processing to replace with KLV data. This replacement process is performed differently depending on whether the replacement target includes video data or not. Thereby, an optimal replacement process can be performed according to the replacement target. First, processing when video data is included in the replacement target will be described.

  First, the analysis unit 22 includes a replacement target range (replacement source range) of the replacement source file 31 included in the replacement information received by the input reception unit 21 and an IndexTable (FIG. 1) included in the replacement source file 31. , The replacement start position of the replacement source file 31 is specified. When the replacement target includes video data, the information processing apparatus 1 replaces at least the data in the replacement source range of the replacement processing unit including the video data set in advance with a replacement work area (predetermined memory 12). Area) at a time and read the data at once. Then, the analysis unit 22 specifies the start position of the video data of the replacement source file read into the work area as the replacement start position (SP) of the replacement source file. Here, the replacement start position SP indicates the storage position of the video data 51a “V0” in FIG. 6A.

  Subsequently, the analysis unit 22 reads data of a preset replacement processing unit (for example, 5 MB) into the replacement work area of the memory 12. For example, as shown in FIG. 6A, the analysis unit 22 reads video data 51a to audio data 52i into the replacement work area of the memory 12 as preset replacement processing unit data. At this time, the analysis unit 22 moves the replacement start position SP by the read data (for example, 5 MB) (for example, SP ′ in FIG. 6A). That is, the replacement start position SP ′ after movement indicates the storage position of the audio data 52j “A12” (the data next to the data read into the replacement work area) stored next to the audio data 52i “A11”. . Then, the analysis unit 22 obtains (extracts) KLV data of the video data 51a (“V0” in FIG. 7A) using the start of the unanalyzed replacement source file 31 stored in the memory 12 as the analysis start memory position (SMP). ) At this time, the analysis unit 22 moves the analysis start memory position SMP by the extracted KLV data. That is, as shown in FIG. 7A, the analysis start memory position SMP ′ after movement indicates the storage position of the audio data 52a “A1”. In this way, the analysis unit 22 extracts the KLV data stored in the replacement source range for each replacement processing unit set in advance according to the type of replacement target data (replacement target type information) to the replacement work area. .

  Subsequently, the analysis unit 22 determines whether the type of KLV data of the replacement source file 31 extracted from the replacement work area is a replacement target. Specifically, the analysis unit 22 determines whether the data type Key included in the extracted KLV data indicates a replacement target. Here, since the replacement target is “video data” and the video data 51a is extracted as KLV data, it is determined that the type of KLV data is the replacement target.

  Next, the analysis unit 22 refers to the replacement target range of the replacement destination file 32 included in the replacement information received by the input reception unit 21 and the index table included in the replacement destination file 32, and performs replacement. The replacement start position of the destination file 32 is specified. Here, as shown in FIG. 6B, the analysis unit 22 specifies the start position of the video data 61a “V′0” of the replacement destination file 32 as the replacement start position DP of the replacement destination file.

  Next, the analysis unit 22 reads preset replacement processing unit data into the replacement work area of the memory 12. For example, as shown in FIG. 6B, the analysis unit 22 reads video data 61a to audio data 62g to the replacement work area of the memory 12 as a replacement target range (for example, FIG. 7A). At this time, the analysis unit 22 moves the replacement start position DP by the read data. That is, as shown in FIG. 6B, the replacement start position DP ′ after movement indicates the storage position of the audio data 62h “A′8” stored next to the audio data 62g “A′7”. Then, the analysis unit 22 sets the head of the unanalyzed replacement destination file 32 stored in the replacement work area of the memory 12 as the analysis start memory position (DMP), and stores the video data 61a (“V′0” in FIG. 7A). Acquire (extract) KLV data. At this time, the analysis unit 22 moves the analysis start memory position DMP by the extracted KLV data. That is, as shown in FIG. 7A, the analysis start memory position DMP ′ after movement indicates the storage position of the audio data 62a “A′1”. As described above, the analysis unit 22 extracts the KLV data stored in the replacement destination range for each replacement processing unit set in advance according to the type of data to be replaced into the replacement work area.

  Subsequently, the analysis unit 22 determines whether or not the KLV data type (Key) of the replacement destination file 32 extracted from the replacement work area is the same as the KLV data type of the replacement source file 31 extracted from the replacement work area. To do. Here, since the video data 51a is extracted as the KLV data of the replacement source file 31, and the video data 61a is extracted as the KLV data of the replacement destination file 32, the analysis unit 22 determines that the types of the KLV data are the same. .

  Then, the replacement unit 23 extracts the video data 61a “V′0” (data stored in the specified replacement destination range) of the replacement destination file 32 extracted from the replacement work area of the memory 12 from the replacement work area. The video data 51a “V0” (data stored in the specified replacement source range) of the replacement source file 31 is replaced (see, for example, FIG. 7B). That is, the replacement unit 23 uses the KLV data (for example, video data 51a “V0”) of the replacement source file 31 extracted from the replacement work area and the KLV data (for example, video data 61a “of the replacement destination file 32 extracted from the replacement work area). V'0 ").

  By repeatedly performing the above processing, the information processing apparatus 1 replaces the data in the replacement destination file 32 with the data in the replacement source file 31. For example, the analysis unit 22 extracts the audio data 52a “A1” as the KLV data of the next replacement source file 31 indicated by the analysis start memory location SMP (for example, SMP ′ in FIG. 7A). Here, since the replacement target is video data, when the audio data 52a “A1” is extracted, the analysis unit 22 determines that it is not the replacement target. When it is determined that it is not the replacement target, the analysis unit 22 extracts the next KLV data (for example, the voice data 52b “A2”), and similarly determines whether it is the replacement target. When this process is repeated, when the video data 51b “V1” is extracted, the analysis unit 22 determines that the video data 51b “V1” is a replacement target.

  Next, the analysis unit 22 extracts the audio data 62a “A′1” as the KLV data of the next replacement destination file 32 indicated by the analysis start memory position DMP ′. Here, since the type of KLV data in the replacement source file 31 is video data, when the audio data 62a “A′1” is extracted, the analysis unit 22 determines that it is not a replacement target. If it is determined that it is not a replacement target, the analysis unit 22 extracts the next KLV data (for example, audio data 62b “A′2”), and similarly determines whether it is a replacement target. When this process is repeated, in the example of FIG. 7, the analysis unit 22 extracts up to the voice data 62g “A′7”. However, since the audio data 62a “A′1” to 62g “A′7” are not video data, the analysis unit 22 determines that they are not replacement targets.

  As described above, when all the data read in the replacement work area is analyzed, the analysis unit 22 refers to the replacement start position DP of the replacement destination file and reads the data of the replacement processing unit set in advance again in the replacement work area. . Here, since the replacement start position DP ′ indicates the storage position of the audio data 62h, the analysis unit 22 sets, for example, data from the audio data 62h “A′8” to the audio data 62n “A′16” in advance. The data is read into the replacement work area of the memory 12 as replacement unit data. At this time, the analysis unit 22 moves the replacement start position DP to the storage position of the audio data 62o “A′17”.

  Then, the analysis unit 22 extracts the data stored in the analysis start memory position DMP, using the start of the unanalyzed replacement destination file 32 in the replacement work area as the analysis start memory position DMP. For example, the analysis unit 22 extracts the audio data 62h “A′8” (see, for example, FIG. 8A). Then, the analysis unit 22 determines whether or not the audio data 62h “A′8” is video data, similarly to the above-described processing. Since the audio data 62h “A′8” is not video data, the analysis unit 22 extracts video data 61b “V′1” as the next KLV data. Since the video data 61b “V′1” is video data, the analysis unit 22 determines that it is a replacement target.

  Then, the replacement unit 23 replaces the video data 61b “V′1” of the replacement destination file 32 extracted from the replacement work area of the memory 12 with the video data 51b “V1” of the replacement source file 31 extracted from the replacement work area. Change (see, for example, FIG. 8B). By repeating the above processing, for example, only video data stored in an MXF file can be replaced quickly and reliably.

  Further, the replacement unit 23 determines whether or not data having a preset capacity (for example, one frame) has been replaced. In the example of FIG. 8B, since the video data of 150 frames and 151 frames (that is, data of one frame or more) are replaced, the replacement unit 23 replaces data of a preset capacity (for example, 1 frame). judge. In this case, the replacement unit 23 stores the data in the storage unit 15 in order from the data in the area indicated by the writing start position WP. Here, the head of the replacement destination file 32 read into the replacement work area is set as the writing start position WP, and the video data 51b “V1” is sequentially started from the video data 51a “V0” (see FIG. 8B) stored at the head. Are stored in the storage unit 15. Thereby, the replacement destination file 32 after the replacement process can be stored in the storage unit 15.

  The arithmetic unit 11 can release the replacement work area of the memory 12 in which the data is stored after storing the data after the replacement process in the storage unit 15. For example, the calculation unit 11 reads the audio data 52i “A11” from the video data 51a “V0” of FIG. 8A read from the replacement source file 31 of FIG. 6A and the replacement destination file 32 of FIG. 6B, and performs the replacement process. The video data 51a “V0” to the video data 51b “V1” in FIG. 8B are released from the replacement work area. Thereby, the usage efficiency of the memory 12 can be improved.

  Then, the information processing apparatus 1 performs the above-described processing on all of the replacement target range (0 to 29 frames) of the replacement source file 31 and the replacement target range (150 to 179 frames) of the replacement destination file 32. Repeat until the replacement process is complete. Thereby, the information processing apparatus 1 does not need to import and export the replacement source file and the replacement destination file, and can perform the replacement process quickly.

  Next, a case where the replacement target is both video data and audio data will be described. Note that the process of reading out the replacement work area from each of the replacement source file 31 (for example, FIG. 6A) and the replacement destination file 32 (for example, FIG. 6B) that has received the input is the same as the process when the replacement target is video data. Since this is the process, the description is omitted. Here, as in the example of FIG. 7A, the video data 51a to the audio data 52i of the replacement source file 31 are read as replacement unit data set in advance into the replacement work area of the memory 12, and the replacement destination file 32 is used. It is assumed that the video data 61a to the audio data 62g are read into the replacement work area.

  In this case, the analysis unit 22 first obtains (extracts) KLV data of the video data 51a (“V0” in FIG. 9A) with the head of the unanalyzed replacement source file 31 as the analysis start memory position SMP. Subsequently, the analysis unit 22 determines whether the type of KLV data of the replacement source file 31 extracted from the replacement work area is a replacement target. Here, since the replacement target is “video data and audio data” and the video data 51a is extracted as KLV data, it is determined that the type of KLV data is the replacement target.

  Next, the analysis unit 22 obtains (extracts) KLV data of the video data 61a (“V′0” in FIG. 9A) using the start of the unanalyzed replacement destination file 32 as the analysis start memory position DMP. Subsequently, the analysis unit 22 determines whether or not the type of KLV data in the replacement destination file 32 extracted from the replacement work area is the same as the type of KLV data in the replacement source file 31 extracted from the replacement work area. Here, since the video data 51a is extracted as the KLV data of the replacement source file 31, and the video data 61a is extracted as the KLV data of the replacement destination file 32, the analysis unit 22 determines that the types of the KLV data are the same. .

  Then, the replacement unit 23 replaces the video data 61a “V′0” of the replacement destination file 32 extracted from the replacement work area of the memory 12 with the video data 51a “V0” of the replacement source file 31 extracted from the replacement work area. Change (see, for example, FIG. 9B).

  Next, the analysis unit 22 extracts the audio data 52a “A1” as the KLV data of the next replacement source file 31 indicated by the analysis start memory position SMP. Here, since the replacement target is “video data and audio data”, when the audio data 52a “A1” is extracted, the analysis unit 22 determines that the replacement target is the replacement target. When the replacement information includes the channel number of the audio data, the analysis unit 22 determines whether the extracted audio data 52 is the channel number of the audio data included in the replacement information.

  Next, the analysis unit 22 extracts the audio data 62a “A′1” as the KLV data of the next replacement destination file 32 indicated by the analysis start memory position DMP. Subsequently, the analysis unit 22 determines whether or not the type of KLV data in the replacement destination file 32 extracted from the replacement work area is the same as the type of KLV data in the replacement source file 31 extracted from the replacement work area. Here, since the voice data 52a “A1” is extracted as the KLV data of the replacement source file 31 and the voice data 62a “A′1” is extracted as the KLV data of the replacement destination file 32, the analysis unit 22 It is determined that the types are the same.

  Then, the replacement unit 23 replaces the audio data 62a “A′1” of the replacement destination file 32 extracted from the replacement work area of the memory 12 with the audio data 52a “A1” of the replacement source file 31 extracted from the replacement work area. Change (see, for example, FIG. 9B). Then, the information processing apparatus 1 repeats the replacement process described above, and the audio data 62b “A′2” to 62g “A′7” of the replacement destination file 32 is converted to the audio data 52b “A2” to 52g of the replacement source file 31. Replace with “A7” (see, for example, FIG. 9).

  Next, the analysis unit 22 extracts the audio data 52h “A8” as the KLV data of the next replacement source file 31 indicated by the analysis start memory position SMP, and determines that it is a replacement target. Subsequently, the analysis unit 22 refers to the analysis start memory position DMP. However, since all the data of the replacement destination file 32 read into the replacement work area has been analyzed, there is no data stored in the reference destination (the next It is determined that there is no KLV data in the replacement destination file 32). In this case, the analysis unit 22 refers to the replacement start position DP of the replacement destination file in FIG. 6B, for example, and reads the replacement processing unit data set in advance again into the replacement work area. Here, since the replacement start position DP indicates the storage position of the audio data 62h, the analysis unit 22 sets, for example, data from the audio data 62h “A′8” to the audio data 62n “A′16” in advance. The data is read into the replacement work area of the memory 12 as replacement processing unit data (see, for example, FIG. 10A). At this time, the analysis unit 22 moves the replacement start position DP to the storage position of the audio data 62o “A′17”.

  Then, the analysis unit 22 extracts the data stored in the analysis start memory position DMP, using the start of the unanalyzed replacement destination file 32 in the replacement work area as the analysis start memory position DMP. For example, the analysis unit 22 extracts the audio data 62h “A′8” (see, for example, FIG. 10A). Then, in the same way as the above-described processing, the analysis unit 22 has the same audio data 62h “A′8” as the type of KLV data (that is, the audio data 52h “A8”) of the replacement source file 31 extracted from the replacement work area. It is determined whether or not. Here, since the audio data 52h “A8” and the audio data 62h “A′8” are both audio data, the analysis unit 22 determines that the types of the KLV data are the same.

  Then, the replacement unit 23 replaces the voice data 62h “A′8” of the replacement destination file 32 extracted from the replacement work area of the memory 12 with the voice data 52h “A8” of the replacement source file 31 extracted from the replacement work area. Change (see, for example, FIG. 10B). Then, the information processing apparatus 1 repeats the replacement process described above, and converts the video data 61b “V′1” and the audio data 62i “A′11” of the replacement destination file 32 into the video data 51b of the replacement source file 31, respectively. “V1” and voice data 52i “A11” are replaced (for example, see FIG. 10).

  Thereafter, the replacement unit 23 stores the data stored in the replacement work area in the storage unit 15 as in the case where the replacement target is “video data”. Then, the information processing apparatus 1 performs the above-described processing on all of the replacement target range (0 to 29 frames) of the replacement source file 31 and the replacement target range (150 to 179 frames) of the replacement destination file 32. Repeat until the replacement process is complete.

  Next, processing when only audio data is replaced will be described. The specific processing is similar to the case where only the video data described above is replaced and the case where both video data and audio data are replaced. When replacing audio data, first, the analysis unit 22 specifies the start position of the audio data of all frames. Specifically, the analysis unit 22 specifies the start position of the audio data corresponding to the number of frames to be replaced (for example, 30 frames) from each of the replacement source file 31 and the replacement destination file 32.

  Next, the analysis unit 22 refers to the start position of the audio data of each identified frame, and reads the KLV data whose data type is audio data into the replacement work area of the memory 12. When the replacement information includes the channel number of the audio data, the analysis unit 22 reads out the audio data 52 (KLV data) indicated by the channel number of the audio data included in the replacement information into the replacement work area. For example, as illustrated in FIG. 11A, the analysis unit 22 reads the KLV data of the 0-frame audio data 52a “A1” of the replacement source file 31 into the replacement work area. Subsequently, the analysis unit 22 reads the KLV data of the 150 frames of audio data 62a “A′1” of the replacement destination file 32 into the memory 12 (FIG. 11A). Then, the replacement unit 23 replaces the KLV data (FIG. 11B). That is, the replacement unit 23 copies the audio data 52a “A1” to the audio data 62a “A′1” and replaces it.

  Subsequently, the analysis unit 22 determines whether or not all the KLV data in the frame has been read. If it is determined that all the KLV data in the frame has not been read, the analysis unit 22 stores the data stored in the frame. Reads out KLV data of type audio data in order. For example, the analysis unit 22 reads out each of the audio data 52b “A2” and the audio data 62b “A′2” as the next audio data (FIG. 11C), and replaces the KLV data. By repeating the above processing, for example, as shown in FIG. 11D, each of the audio data 62a “A′1” to 62h “A′8” stored in the replacement destination file 32 becomes the audio data 52a “A1” to 52h “A8”.

  If the analysis unit 22 determines that all the KLV data in the frame has been read, for example, as shown in FIG. 11D, the analysis unit 22 stores the audio data 62a “A′1” through the replacement destination file 32. When each of the 62h “A′8” is replaced with each of the audio data 52a “A1” to 52h “A8”, the replaced KLV data is stored in the storage unit 15. That is, the replacement unit 23 stores the data of the replacement destination file for one frame read into the replacement work area of the memory 12 in the storage unit 15 as the data after replacement. In addition, the process which memorize | stores the data stored in the memory 12 in the memory | storage part 15 is not restricted for every frame.

  Then, the analysis unit 22 determines whether or not the KLV data (audio data) in all the frames has been read into the replacement work area, and when it is determined that the KLV data in all the frames has not been read, Similar processing is repeated for frames (for example, one frame of the replacement source file and 151 frames of the replacement destination file). On the other hand, if it is determined that the KLV data in all frames has been read, the audio data replacement process ends. Thus, since the method of replacement processing is changed according to the replacement target, replacement processing can be performed quickly and efficiently.

[Operation]
Next, the operation of the information processing apparatus 1 will be described with reference to FIGS. FIG. 12 is a flowchart for explaining the replacement process. FIG. 13 is a flowchart for explaining the video data replacement process. FIG. 14 is a flowchart for explaining the audio data replacement process.

  In the replacement process of FIG. 12, first, the input receiving unit 21 receives input of a replacement source file and a replacement destination file (step S1). For example, the input receiving unit 21 receives input of an MXF file that is a replacement source and an MXF file that is a replacement destination via the input unit 13. Here, it is assumed that the input receiving unit 21 receives input of a replacement source file of 30 frames (for example, 1 second) and a replacement destination file of 300 frames (for example, 10 seconds). It is assumed that the video data codec of the replacement source file and the replacement destination file is “AVC-Intra 100 Mbps”, and the audio data codec is “8ch 16 bits”.

  Subsequently, the input receiving unit 21 receives input of replacement information (step S2). The replacement information is information including, for example, the replacement target range of the replacement source file, the replacement target range of the replacement destination file, and the type of data to be replaced. The replacement target range is specified by, for example, a time code (hour: minute: second: frame) indicating a replacement start position and a replacement size. The types of data to be replaced are, for example, video data, audio data, video data and audio data, and the like. Here, it is assumed that the first frame (0 frame) to 29 frames of the replacement source file are acquired as the replacement target range of the replacement source file, and the 150th frame to 179th frame are acquired as the replacement target range of the replacement destination file. . Also, assume that video data is acquired as the type of data to be replaced.

  Next, the analysis part 22 acquires metadata (step S3). For example, the analysis unit 22 acquires (extracts) metadata from each of the replacement source file 31 and the replacement destination file 32. Subsequently, the analysis unit 22 determines whether or not replacement is possible (step S4). For example, the analysis unit 22 determines whether the replacement target range of the replacement source file included in the replacement information received in the process of step S2 is present in the replacement source file received in the process of step S1. Determine whether. Similarly, the analysis unit 22 determines whether the replacement target range of the replacement destination file exists in the replacement destination file. Further, for example, when the type of data to be replaced includes video data, the analysis unit 22 acquires video codec information (for example, AVC-Intra) of the replacement source file and the replacement destination file as metadata, and acquires the acquired video It is determined whether the codec information matches. Furthermore, for example, when the type of data to be replaced includes audio data, the analysis unit 22 acquires and acquires the audio codec information (for example, PCM format) of the replacement source file and the replacement destination file as metadata. It is determined whether the audio codec information matches.

  If it is determined that the replacement is not possible in the process of step S4 (step S4: No), the replacement process of FIG. On the other hand, if it is determined that the replacement is possible (step S4: Yes), the process proceeds to step S5. Here, as shown in FIG. 5, there are a replacement target range (0 to 29 frames) of the replacement source file and a replacement target range (150 to 179 frames) of the replacement destination file. As described above, the video codec and audio codec of the replacement source file and the replacement destination file are the same. Therefore, the analysis unit 22 determines “Yes” in the process of step S4.

  If it is determined in step S4 that the replacement is possible (step S4: Yes), the analysis unit 22 determines whether the replacement target includes video data (step S5). When it is determined that the video data is included in the replacement target (step S5: Yes), the video data replacement process of FIG. 13 is performed (step S6). On the other hand, if it is determined that the video data is not included in the replacement target (step S5: No), here, if only the audio data is included in the replacement target, the audio data replacement process of FIG. 14 is performed (step S7). ). Here, since “video data” is acquired as a replacement target in the process of step S2, the process proceeds to step S6. The video data replacement process will be described with reference to FIG.

  FIG. 13 is a flowchart for explaining the video data replacement process. In the video data replacement process, first, the analysis unit 22 identifies the replacement start position of the replacement source file (step S21). For example, the analysis unit 22 has received the input in the replacement target range (replacement source range) of the replacement source file 31 included in the replacement information received in the processing in step S2 of FIG. 12 and the processing in step S1. With reference to the IndexTable part included in the replacement source file 31, the replacement start position of the replacement source file is specified. When replacing video data, or when replacing both video data and audio data, the information processing apparatus 1 continuously reads out the data of preset replacement processing units in the replacement source range and replaces the data. I do. Here, the analysis unit 22 specifies the start position (SP) of the video data (for example, video data 51a “V1”) of the replacement source file as the replacement start position of the replacement source file.

  Subsequently, the analysis unit 22 reads data of a preset replacement processing unit (for example, 5 MB) into the replacement work area of the memory 12 (step S22). For example, the analysis unit 22 reads the data from the video data 51a to the audio data 52i to the replacement work area of the memory 12 as replacement unit data. At this time, the analysis unit 22 moves the start position SP by the read data (for example, 5 MB). Then, the analysis unit 22 extracts the KLV data of the replacement source file 31 (Step S23). Here, the analysis unit 22 uses the start of the replacement work area of the memory 12 from which the replacement source file has been read as the analysis start memory position (SMP), and extracts KLV data constituting the video data 51a “V1”. At this time, the analysis unit 22 moves the analysis start memory position SMP by the read KLV data.

  Subsequently, the analysis unit 22 determines whether or not the type of KLV data extracted in the process of step S23 is a replacement target (step S24). Specifically, the analysis unit 22 determines whether the data type Key included in the KLV data indicates a replacement target (video data or audio data). Here, the replacement target is “video data”, and the video data 51a “V1” is extracted as the KLV data. Therefore, “Yes” is determined in the process of step S24, and the process proceeds to step S26.

  On the other hand, when it is determined in step S24 that it is not a replacement target (step S24: No), for example, when the voice data 52a “A1” is extracted as KLV data, the analysis unit 22 performs the KLV data of the next replacement source file 31. It is determined whether or not there is (step S25). If it is determined that there is KLV data of the next replacement source file 31 (step S25: Yes), the process returns to step S23, and the KLV data of the next replacement source file 31 (for example, KLV data of the audio data 52b “A2”). Is extracted and the same process is repeated.

  On the other hand, if it is determined in step S25 that there is no KLV data of the next replacement source file 31 (step S25: No), for example, if the KLV data extracted in the process of step S23 is the audio data 52i, the process Returns to step S22, and the next replacement source range is read. For example, the analysis unit 22 reads 5 MB of data from the audio data 52j into the replacement work area of the memory 12, and repeats the same processing.

  If it is determined in step S24 that the type of KLV data is a replacement target (step S24: Yes), the analysis unit 22 identifies the replacement start position of the replacement destination file (step S26). For example, the analysis unit 22 is included in the replacement target range of the replacement destination file included in the replacement information received in the process of step S2 in FIG. 12 and the replacement destination file received in the process of step S1. With reference to the IndexTable part, the replacement start position of the replacement destination file is specified. Here, the analysis unit 22 identifies the start position (DP) of the video data (for example, video data 61a “V′1”) of the replacement destination file as the replacement start position of the replacement destination file.

  Next, the analysis unit 22 reads the preset replacement processing unit data into the replacement work area of the memory 12 (step S27). For example, the analysis unit 22 reads the data from the video data 61a “V′1” to the audio data 62g “A′7” stored in the storage unit 15 to the replacement work area of the memory 12 as replacement processing unit data. . At this time, the analysis unit 22 moves the start position DP by the read data. And the analysis part 22 extracts the KLV data of the replacement destination file 32 (step S28). Here, the analysis unit 22 uses the beginning of the replacement work area of the memory 12 from which the replacement destination file has been read as the analysis start memory position (DMP), and extracts KLV data constituting the video data 61a “V′1”. At this time, the analysis unit 22 moves the analysis start memory position DMP by the read KLV data.

  Subsequently, the analysis unit 22 determines whether or not the type (Key) of the KLV data extracted in the process of Step S28 is the same as the type of KLV data extracted in the process of Step S23 (Step S29). Here, the replacement object extracted in the process of step S28 is “video data”, and the video data 51a “V′1” is extracted as the KLV data. Therefore, “Yes” is determined in the process of step S29. Then, the process proceeds to step S31.

  On the other hand, when it is determined in step S29 that the types of the KLV data are not the same (step S29: No), for example, when the audio data 62a is extracted as the KLV data, the analysis unit 22 performs the KLV of the next replacement source file 31. It is determined whether there is data (step S30). If it is determined that there is KLV data of the next replacement source file 31 (step S30: Yes), the process returns to step S28, and the KLV data of the next replacement source file 31 (for example, the KLV of the audio data 62b “A′2”). Data) and the same processing is repeated.

  On the other hand, if it is determined in step S30 that there is no KLV data of the next replacement source file 31 (step S30: No), for example, the KLV data extracted in the process of step S28 is the audio data 52g “A7”. In this case, the process returns to step S27, and the next replacement source range is read. For example, the analysis unit 22 reads 5 MB of data from the video data 61b “V′2” into the memory 12, and repeats the same processing.

  If it is determined in step S29 that the types of KLV data are the same (step S29: Yes), the replacement unit 23 replaces the KLV data (step S31). For example, the replacement unit 23 is video data 61a “V′1”, which is KLV data of the replacement destination file extracted in the replacement work area of the memory 12, and is KLV data of the replacement source file extracted in the replacement work area. The video data 51a is replaced with “V1”. That is, the replacement unit 23 copies the KLV data of the replacement source file read to the memory 12 to the KLV data of the replacement destination file read to the memory 12 and replaces it.

  Next, the analysis unit 22 determines whether data of a preset frame size (for example, one frame) has been replaced (step S32). If it is determined that the data of the preset frame size has not yet been replaced (step S32: No), the process returns to step S22 and the subsequent processes are repeated.

  On the other hand, when it is determined that the data of the preset frame size has been replaced (step S32: Yes), the replacement unit 23 stores the replaced data in the storage unit 15 (step S33). That is, the replacement unit 23 stores the data of the replacement destination file stored in the memory 12 in the storage unit 15 as the data after replacement.

  Next, the analysis unit 22 determines whether all replacement source data has been replaced (step S34). When it is determined that all replacement source data has not been replaced (step S34: No), the processing returns to step S22, and the subsequent processing is repeated. On the other hand, when it is determined that all the replacement source data has been replaced (step S34: Yes), the replacement processing of the video data ends.

  Next, the audio data replacement process will be described with reference to FIG. In the voice data replacement process, first, the analysis unit 22 specifies the start position of the voice data of all frames (step S51). Specifically, the analysis unit 22 specifies the start position of the audio data for the number of frames to be replaced from each of the replacement source file and the replacement destination file.

  Next, the analysis unit 22 reads KLV data from a predetermined frame of the replacement source file (step S52). That is, the analysis unit 22 refers to the start position of the audio data of each frame specified in the process of step S51, and reads the KLV data whose data type is audio data into the replacement work area of the memory 12. For example, the analysis unit 22 reads the 0-frame audio data 52 a “A1” KLV data into the replacement work area of the memory 12.

  Subsequently, the analysis unit 22 reads out KLV data from a predetermined frame of the replacement destination file, similarly to the process of step S52 (step S53). For example, the analysis unit 22 reads the KLV data of the 150 frames of audio data 62 a into the replacement work area of the memory 12. Then, the replacement unit 23 replaces the KLV data (Step S54). That is, the replacement unit 23 copies the KLV data (audio data 52a “A1”) read out in step S52 to the KLV data (audio data 62a “A′1”) read out in step S53. .

  Subsequently, the analysis unit 22 determines whether all the KLV data in the frame has been read (step S55). If it is determined that all the KLV data in the frame has not been read (step S55: No), the process returns to step S52, and the KLV data stored in the frame and whose data type is audio data is replaced in order. Read to work area. For example, the analysis unit 22 reads out each of the audio data 52b “A2” and the audio data 62b “A′2” as the next audio data, and replaces the KLV data.

  On the other hand, when it is determined that all the KLV data in the frame has been read (step S55: Yes), for example, the analysis unit 22 and each of the audio data 52a “A1” to 52h “A7” and the audio data 62a “A ′”. When “1” to 62h “A′7” are read, the process proceeds to step S56. Then, the replacement unit 23 stores the replaced KLV data in the storage unit 15 (step S56). That is, the replacement unit 23 stores the data of the replacement destination file for one frame stored in the replacement work area of the memory 12 in the storage unit 15 as the data after replacement.

  Then, the analysis unit 22 determines whether or not the KLV data (audio data) in all frames has been read (step S57). If it is determined that the KLV data in all the frames has not been read (step S57: No), the process returns to step S52, and for the next frame (for example, one frame of the replacement source file and 151 frames of the replacement destination file). Repeat the same process. On the other hand, when it is determined that the KLV data in all the frames has been read (step S57: Yes), the audio data replacement process ends.
