1 is a schematic diagram showing a processing apparatus 100 of the present invention.

A common file and a unique file may be requested together in a specific executor 90 to perform a specific function. The executor 90 may include a program for executing various functions, or a computing device on which the program is mounted. For example, an image editing program such as Edius or a terminal equipped with Edius may correspond to the launcher 90 .

The executor 90 may perform various functions when input data is obtained. In some cases, in order to perform a specific function not supported by the other executors 90, the specific executor 90 may require a unique file dedicated to the executor 90, not a general public file.

For example, Edius, which is one of the video editing programs, may perform image editing like other editing programs using a common file corresponding to a general image file. However, in order to perform the 'editing while recording' function, which is a unique function not found in other editing programs, Edius requires a unique file dedicated to Edius. Specifically, in order to perform an editing function during recording, Edius requires a CMF (Common Media Format) file or a dedicated index file. The CMF file or index file is a file that is output only from the K2 video server of Grass Valley, which is the same production company as Edius, and cannot output the file from a general video server of another company. As a result, when using a general video server, Edius' editing function during recording cannot be used.

The processing device 100 of the present invention automatically generates the unique file required by the specific executor 90, the obtaining unit 110, the extracting unit 130, the generating unit 150, the providing unit 170, analysis part 190 may be included.

The acquisition unit 110 may acquire the first file d1 having the same format as the common file c from the first server 10 .

The common file c may indicate a file of a format commonly used by multiple types of servers or multiple types of executors 90 . For example, an MXF (Material eXchange Format) file may be used as an image file in the image editing field. The MXF file may correspond to a file used in various types of servers or various types of executors 90 .

If the common file c requested by the executor 90 is an MXF file, the obtaining unit 110 may obtain the first file d1 corresponding to the MXF file having the same format as the common file c from the second server 20 .

The extraction unit 130 may extract components of the unique file i from the first file d1.

The unique file i may have a format used only by a specific executor 90 . The unique file i has meaning only in a specific executor 90 , and may not participate in any function in the other executors 90 , like the dummy file. In particular, the unique file i may not even be loaded in other executors 90 .

The extraction unit 130 may extract the components of the unique file i from the first file d1 having the same format as the common file c by using the correlation between the common file c and the unique file i.

For example, if the unique file i has an association in which the header partition pack of the common file c is included, the extraction unit 130 determines the header partition pack of the common file c as a component of the unique file i can do. In addition, the extractor 130 may extract the header partition pack from the first file d1 having the same format as the common file c.

The generator 150 may generate a second file d2 compatible with the original file i by using the components extracted from the first file d1 . To be compatible with the native file i, the second file d2 may be formed in the same format as the native file i. For example, when the unique file i is an index file dedicated to Edius or K2 video server, the generator 150 may generate the second file d2 in the same format as the corresponding index file.

The executor 90 may be designed to receive a common file c and a unique file i output from the second server 20 to perform a specific function.

The analysis unit 190 may analyze the structure of the unique file i through the analysis of the unique file i output from the second server 20 in advance. As an example, the analysis unit 190 may analyze which components of the common file c are included in the unique file i through comparative analysis between the shared file c and the unique file i output from the second server 20 in advance. .

The extraction unit 130 may extract components of the unique file i from the first file d1 output from the first server 10 according to the structure of the unique file i analyzed by the analysis unit 190 . As an example, the extraction unit 130 may extract components of the unique file i from the first file d1 obtained from the first server 10 based on the analysis result of the analysis unit 190 . The components of the unique file i extracted by the extraction unit 130 may be used to generate the second file d2 by the generation unit 150 .

According to the present embodiment, the components of the unique file i may be extracted regardless of the type of the first file d1, and the second file d2 may be generated. Accordingly, according to the analysis unit 190 , the processing device 100 of the present invention may be applied to the executor 90 in various fields including the field of image editing.

The components of the unique file i are, for example, the header partition pack of the first file d1, the metadata of the first file d1, the index table of the first file d1, the technical information of the first file d1 information), and at least one of a basic encoding rule of the first file d1.

If the executor 90 includes an image editor such as Edius for editing an image, the component may further include video information of the first file. The video information may include resolution, number of colors, saturation, brightness, luminance, refresh rate, and the like.

As mentioned above, when the executor 90 is Edius, which is an image editor, the common file c and the first file d1 may be MXF (Material eXchange Format) files. The unique file i and the second file d2 may be an index file unique to Edius. The first file d1 obtained from the first server 10 and the second file d2 generated by the generator 150 may be provided together to Edius for the 'editing function during recording'. The editing function during recording may literally mean a function of recording an image and editing the recorded image in real time.

Specifically, the acquisition unit 110 may acquire the first file d1 corresponding to the video being recorded from the first server 10 . The extraction unit 130 may analyze the first file d1 acquired through the acquisition unit 110 in real time to extract components of the unique file i.

The generator 150 may generate the second file d2 in real time by using the extracted components.

The providing unit 170 may match the second file d2 generated by the generating unit 150 with the first file d1 serving as a source of the second file d2 and provide it to the executor 90 in real time.

2 is a schematic diagram showing a comparative embodiment in which the processing device 100 of the present invention is excluded.

In the case of Edius editing equipment based on a general video server in the field of video editing or broadcast editing, a specific function to edit during recording or copying is not possible. This function is blocked by Edius itself because the information of the MXF (Material Exchange Format) file, a container file format for digital video and audio media, is incomplete.

Edius is a video editing software package for personal computers (PCs) with Windows installed. Edius is a Non-Linear Editing System (NLE) compatible with most modern video formats. Edius is a product of GV (Grass Valley).

If there is no footer of the MXF file, Edius does not register the MXF file in the timeline for editing. The MXF file may include header, body, and footer partitions. In this case, a complete MXF file can be made only when the setting contents exist in the header and footer partitions. Without a footer, various processes for an edited file during recording may be stopped, or various processes may be stopped during copying, which corresponds to a so-called broken file.

In order to support various platforms, Edius is exceptionally able to load and edit broken files.

As an example, Edius may edit a broken file on condition that it is connected to the K2 video server in Grass Valley, which is the same video server as the production company, through a SAN. A storage area network (SAN) refers to a network that connects different types of data storage devices to a data server and manages them collectively.

An example of a broken file is a file that is being recorded in real time. This means that Edius connected to the K2 video server via SAN supports the editing function during recording.

The processing device 100 of the present invention can emulate the operation of the K2 video server so that the editing function during recording can be used in various video servers using Edius.

When recording, K2 Video Server creates a CMF (Common Media Format) file (with the extension .cmf), which is a unique file format. At this time, Edius directly accesses the storage of the K2 video server and performs editing functions during recording using a file format such as CMF. The CMF file format cannot be used by other video servers or recording equipment.

The CMF file format may include its own components, for example, Video.m0, Audio.a0, Audio.a1, Timecode.t0, Data.n0, Thumbnail.jpg, and the like. The CMF file with the corresponding component cannot be loaded or used on another server or another executor 90 .

A specific Edius includes a function to export the video file output from the system combined with the K2 video server and a specific Edius to an MXF file so that other Edius installed on another video server can load and work. . At this time, the specific Edius additionally creates an '.index' file, which is a separate index file from the MXF file. MXF files and other Edius files with index files can be edited in real time.

The processing device 100 of the present invention may store an image being recorded as an MXF file in real time by using the corresponding feature and simultaneously generate a related index file. In addition, the processing device 100 of the present invention may provide the MXF file stored simultaneously with recording to Edius in real time. Also, the processing device 100 may provide the index file generated simultaneously with recording to Edius in real time.

After receiving the MXF file and index file in real time, Edius can edit the video in real time regardless of whether it is connected to the K2 video server.

In summary, if real-time storage of MXF files, real-time creation of index files, and real-time transmission of MXF files and index files to Edius are performed, the editing function during recording can be implemented as it is, regardless of the type of server.

3 is a schematic diagram illustrating the operation of the processing device 100 of the present invention. 4 is a schematic diagram illustrating an index entry structure of Edius.

As an example, the processing device 100 downloads an image being recorded from a server other than the K2 video server, for example, a video server of Harmonic or Imagine Communications in real time, and an index file through analysis of the image. can create

The acquisition unit 110 may acquire files in a format different from the common file c of the second server 20 from various types of the first server 10 . For example, the specific first server 10 may provide the MP4 file to the obtaining unit 110 instead of the MXF file. The acquisition unit 110 may be provided with a conversion module for converting a file of a different format obtained from the first server 10 into a first file having the same format as the common file c.

The index file may contain information required by Edius, including header information. For example, the processing device 100 may provide the same structure as the existing index file provided by the K2 video server so that Edius performs an editing function during recording regardless of the server.

In the index entry of Edius, a byte section indicating the start of the index, a byte section representing the audio frame size, a byte section representing a temporal offset, a byte section representing a keyframe offset, A byte section representing a start offset, a byte section representing a frame size, a byte section representing a division value, and a byte section representing a slice offset may be included in this order.
