Description

A method and apparatus for managing broadcast content based on software definition {METHOD AND APPARATUS FOR MANAGING BROADCASTING CONTENTS OF BASED SOFTWARE DEFINITION}

The disclosed embodiment relates to a broadcast content management technology.

Existing broadcast production systems were able to produce professional broadcasts (including terrestrial broadcasts and cable broadcasts) only by using dedicated hardware equipment based on SDI (Serial Digital Interface). However, since SDI-based broadcasting equipment has an independent interface for each brand, it is very difficult to interwork with broadcasting equipment of other brands, and therefore, it is inevitably dependent on broadcasting equipment of a specific brand in the system construction stage.

In addition, the broadcast production system of the SDI standard has a problem in that it is difficult to extend from high definition (HD) to ultra high definition (UHD). In other words, the existing SDI-based broadcasting production system is capable of producing HD-class broadcasting due to the limitation of the data transmission amount of SDI, but the expansion to UHD-class broadcasting production environment is very inefficient in terms of cost and management.

To overcome this limitation, solutions such as 12G-SDI have come out, but as the physical distance increases, the safety of the video transmission of the method decreases sharply. In addition, in order to use 12G-SDI, all existing SDI equipment must be replaced, and in order to produce broadcast contents from 4K UHD to 8K UHD or higher in the future, replacement with new equipment is inevitable.

In the case of UHD-class uncompressed broadcast data, data transmission of at least 10 Gbps is required, and the current 12G-SDI can accommodate this at 11.88 Gbps, but there is a problem that the physical distance can be transmitted up to 10 Km. To solve this problem, an IP-based data transmission method is applied to a broadcast production system. In the case of IP-based data transmission, a system of 100 Gbps standard is generally used, and it is cost-effective, and thus the transition from an SDI-based system to an IP-based system is being made in producing UHD-class broadcasting contents.

Broadcasting equipment supporting an IP-based interface is increasing, but equipment that provides an interworking interface to provide a function to centrally control the unique function of the corresponding equipment is insufficient. Even if equipment that provides an interlocking interface is used, a system that centrally monitors all broadcasting equipment for system management incurs additional costs due to separate construction. In the case of a current computing device (eg, x86), not only is IP network support possible, but also computing performance is at a level capable of processing basic broadcasting equipment. Therefore, by implementing a software-based broadcasting function in a high-performance server equipment, it becomes possible to develop a system capable of controlling all centrally based on IP.

On the other hand, UHD broadcast content requires a very large content storage space of about 6.56 TB per hour. The broadcast production system basically goes through the process of video recording and ingest → video editing → final broadcast transmission → broadcast transmission.Comparing this to HD broadcast content production, UHD broadcast content requires at least four times more storage space. Is done.

As described above, the next-generation broadcast production system is going to develop a software definition-based broadcast production system, but in terms of storing broadcast contents, UHD broadcast content requires at least four times more storage space than HD broadcast content. An efficient storage management scheme that can centrally control duplicate contents that inevitably occur during a broadcast production process is a problem that must be solved in a next-generation UHD broadcasting system.

A hash table can be created by matching each value.

The broadcast content structuring module generates one hash value having a unique value for the composite broadcast content based on hash values for each unit block of the broadcast content, and uses the generated hash value of the composite broadcast content. Can be set by ID.

The broadcast content registration module may determine whether to store each unit block of the composite broadcast content to be registered by comparing the hash table of the composite broadcast content to be registered with the hash table of the previously registered composite broadcast content.

1 is a block diagram showing a configuration of a software definition based broadcast content management apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the broadcast content management apparatus 100 may include a broadcast content structuring module 102, a broadcast content registration module 104, a broadcast content editing module 106, and a storage management module 108. .

The broadcast content structuring module 102 may structure the input broadcast content into a tree structure having an upper folder and a subordinate folder thereof. That is, the broadcast content structuring module 102 generates composite broadcast content by tree-structuring broadcast content. When the generated composite broadcast content is located in an upper folder, it may include a plurality of subfolders dependent thereon.

2 is a diagram schematically showing a tree structure of composite broadcast content according to an embodiment of the present invention. Referring to FIG. 2, a content folder 204 and a meta data folder 206 may be included as subfolders of the composite broadcast content folder 202.

The broadcast content structuring module 102 may create and structure a composite broadcast content folder 202, a content folder 204, and a meta data folder 206 for input broadcast content. In the disclosed embodiment, "folder" may be a term for expressing a logical upper and lower concept rather than a physically existing folder. The tree structure of such complex broadcast content is only an exemplary embodiment, but is not limited thereto.

Registered broadcast content may be stored in the content folder 204. That is, the content folder 204 may store actual broadcast content such as video or audio.

Meta data folder 206 may store meta data for broadcast content. In an exemplary embodiment, the meta data may include identification meta data for identification of broadcast content and meta data of broadcast content. For example, the metadata may include the title (title) of the broadcast content, the copyright holder of the broadcast content, the creation date and time of the broadcast content, and information on a person appearing in the broadcast content.

In addition, the composite broadcast content folder 202 may include a structure description file 208 including description information on the structure of the composite broadcast content. The structure description file 208 has a tree structure of composite broadcasting contents in a form, and information on which files are stored in the upper folder and the subordinate folder thereof may be included.

The broadcast content structuring module 102 may divide broadcast content into unit blocks having a preset time. In an exemplary embodiment, the broadcast content structuring module 102 may divide the broadcast content into frames (video frames or audio frames) (or seconds, etc.). The broadcast content structuring module 102 may generate a hash value for each unit block. The broadcast content structuring module 102 may generate a hash value for each unit block such that a hash value of each unit block becomes a unique value (ie, a unique value). Here, the difference in the hash value of the unit block may mean that the contents of the broadcast content in the section corresponding to the unit block are different.

The broadcast content structuring module 102 may generate a unique ID for the composite broadcast content based on hash values for each unit block of the broadcast content. In an exemplary embodiment, the broadcast content structuring module 102 may generate one hash value from hash values for each unit block of the broadcast content, and the generated hash value is a unique ID (complex broadcast content). Broadcast content ID).

The broadcast content structuring module 102 may match the composite broadcast content ID with unit blocks of the corresponding broadcast content, and match hash values for each unit block of the broadcast content with the corresponding unit block, and store it in a hash table. For example, each unit block may be arranged in chronological order in the corresponding broadcast content. The hash values of the content folder 204 and its subordinate data may be stored and managed in a hash table. In addition, hash values of the metadata folder 206 and its subordinate data may be stored and managed in a hash table.

Table 1 is a table showing a hash table for composite broadcast content according to an embodiment of the present invention.

Complex broadcasting content ID Unit block Hash value

The broadcast content registration module 104 may register structured composite broadcast content through the broadcast content structuring module 102. The broadcast content registration module 104 may store and register the composite broadcast content and the hash table for the composite broadcast content in the storage 108.

When registering the composite broadcast content, the broadcast content registration module 104 may compare hash values of each unit block of the composite broadcast content to be registered with the hash value of a previously registered hash table. The broadcast content registration module 104 stores each unit block of the composite broadcast content according to whether a hash value equal to the hash value of the previously registered hash table exists among the hash values of each unit block of the composite broadcast content to be registered. You can decide whether or not.

3 is a diagram for describing a new registration of composite broadcast content according to an embodiment of the present invention. Referring to FIG. 3, when a composite broadcast content A is to be registered, the composite broadcast content A may be divided into 24 unit blocks (eg, frames).

Here, when the hash value of the unit blocks 7 to 10 is the same as the hash value of the unit blocks 15 to 18 of the previously registered composite broadcasting content (B), the broadcast content registration module 104 Among the unit blocks of the broadcast content (A), unit blocks 1 to 6 and unit blocks 11 to 24 (i.e., corresponding to hash values that do not exist in the hash table of the previously registered composite broadcast content) Unit blocks) may be stored, and unit blocks 7 to 10 (ie, unit blocks corresponding to hash values existing in the hash table of the previously registered composite broadcast content) may not be stored.

That is, the hash value of the unit blocks 7 to 10 of the composite broadcasting content (A) is the same as the hash value of the unit blocks 15 to 18 of the previously registered composite broadcasting content (B). It means that the contents of the composite broadcast content of are the same, and the unit blocks from #15 to #18 of the composite broadcast content (B) are already stored, and from #7 to #10 of the composite broadcast content (A) The unit blocks of may not be stored in order to prevent redundant storage. At this time, only hash values may be stored for unit blocks 7 to 10 of the composite broadcast content A. Accordingly, it is possible to reduce the amount of data stored when registering composite broadcasting content.

The broadcast content editing module 106 may register new composite broadcast content by editing previously registered composite broadcast contents. The broadcast content editing module 106 may extract hash values of some unit blocks from a hash table of the previously registered composite broadcast content, and then combine the extracted hash values to generate a hash table for a new composite broadcast content.

FIG. 4 is a diagram for explaining a state in which a new composite broadcast content is generated by editing previously registered composite broadcast contents according to an embodiment of the present invention. Referring to FIG. 4, it is assumed that a new composite broadcast content is generated by using a pre-registered composite broadcast content A and a pre-registered composite broadcast content B.

Here, the unit blocks 6 to 19 of the unit blocks of the previously registered composite broadcasting content (A) and the unit blocks 12 to 16 of the unit blocks of the pre-registered composite broadcasting content (B) By combining, it is possible to create a new composite broadcast content C.

Specifically, the broadcast content editing module 106 may extract hash values corresponding to unit blocks 6 through 19 from the hash table of the previously registered composite broadcast content A. In addition, the broadcast content editing module 106 may extract hash values corresponding to unit blocks 12 to 16 from the hash table of the previously registered composite broadcast content B.

The broadcast content editing module 106 converts hash values corresponding to the unit blocks 6 to 19 extracted from the hash table of the previously registered composite broadcast content A, from 1 to 14 of the new composite broadcast content C. The hash values of the unit blocks up to are set, and the hash values corresponding to the unit blocks 12 to 16 extracted from the hash table of the previously registered composite broadcast content (B) are set to 15 of the new composite broadcast content (C). You can set the hash values of the unit block from No. to No. 20.

That is, the broadcast content editing module 106 includes hash values corresponding to unit blocks 6 to 19 of the previously registered composite broadcast content A and 12 to 16 of the previously registered composite broadcast content B. A hash table for a new composite broadcast content C may be generated based on a hash value corresponding to a unit block up to. The broadcast content editing module 106 may generate a unique ID for a new composite broadcast content C based on hash values included in the generated hash table and store it in the hash table.

Here, the broadcast content editing module 106 may store only a hash table generated by combining hash values of the composite broadcast content A and B previously registered for the new composite broadcast content C. That is, since the unit blocks corresponding to the hash values of the previously registered composite broadcast content A and B are already stored, only the hash table can be stored and managed for the new composite broadcast content C. In other words, the new composite broadcast content C can be expressed in a logical structure using a hash table instead of newly creating and storing a physical file. Accordingly, it is possible to minimize the amount of stored data while registering new composite broadcasting contents by editing the previously registered composite broadcasting contents.

When the broadcast content editing module 106 attempts to generate a physical file for the composite broadcast content C, it extracts unit blocks corresponding to each hash value from the hash table of the composite broadcast content C, and extracts the unit block. It is possible to generate a file for the composite broadcast content C by arranging the listens according to the time order.

In addition, when a command to delete a previously registered composite broadcast content is input, the broadcast content editing module 106 is a unit corresponding to a hash value equal to the hash value of other composite broadcast content among hash values of the previously registered composite broadcast content. Blocks can be deleted except for.

FIG. 5 is a diagram for explaining a case of deleting a previously registered composite broadcast content according to an embodiment of the present invention. Referring to FIG. 5, when a delete command for a pre-registered composite broadcast content A is input, the broadcast content editing module 106 includes unit blocks 1 to 24 of the pre-registered composite broadcast content A. Among the hash values, it is possible to check whether there is a hash value that is the same as that of other composite broadcasting contents. Here, the unit blocks 1 to 24 of the previously registered composite broadcast content A may be stored in the storage 108.

For example, hash values of unit blocks 7 to 10 of the previously registered composite broadcasting content (A) are hash values of unit blocks 15 to 18 of the previously registered composite broadcasting content (B) In the case of the same, the broadcast content editing module 106 corresponds to the unit blocks 1 to 6 and the unit blocks 11 to 24 of the previously registered composite broadcast content A. You can delete the hash values. On the other hand, for the unit blocks 7 to 10 of the previously registered composite broadcasting content A, the corresponding unit blocks and hash values corresponding thereto may be maintained without deleting them.

Here, the unit blocks 15 to 18 in the pre-registered composite broadcast content B may be a case in which unit blocks 7 to 10 of the pre-registered composite broadcast content A are edited and used. That is, the unit blocks 15 to 18 in the previously registered composite broadcasting content (B) do not store the actual unit blocks, but correspond to the unit blocks 7 to 10 in the previously registered composite broadcasting content (A). It may be that only the hash value is stored. Accordingly, when a delete command of the previously registered composite broadcast content A is input, the unit blocks 7 to 10 of the previously registered composite broadcast content A can be maintained as it is.

On the other hand, when a command to delete a previously registered composite broadcast content is input, the broadcast content editing module 106 corresponds to a hash value equal to the hash value of another composite broadcast content among the hash values of the previously registered composite broadcast content. If the unit block corresponding to the hash value is not stored, the hash value can be deleted.

For example, as shown in FIG. 4, the hash values of unit blocks 6 to 19 are extracted from the composite broadcasting content (A), and units 12 to 16 are extracted from the composite broadcasting content (B). It is assumed that the hash table of the composite broadcast content C is generated by extracting the hash values of the blocks.

Here, when a deletion command for the composite broadcast content C is input, the broadcast content editing module 106 determines the hash value of the unit blocks 1 to 14 in the composite broadcast content C. ) Is the same as the hash value of the unit blocks 6 through 19, and the hash value of the unit blocks 15 through 20 in the composite broadcasting content (C) is 12 through 16 in the composite broadcasting content (B). Even if the hash value of the unit blocks up to is the same, the unit blocks corresponding thereto are actually stored in correspondence with other complex broadcasting contents (A, B), so the hash values from 1 to 20 in the complex broadcasting content (C) You can delete all of them.

The storage management module 108 may manage one or more storages 110 for storing broadcast content-related data registered through the broadcast content management device 100. That is, the storage 110 may match and store the registered composite broadcast content and a hash table corresponding thereto. In an exemplary embodiment, the storage 110 may be implemented as virtualized storage or cloud storage.

The storage management module 108 may manage a storage path of broadcast content-related data on the storage 110. Here, the broadcast content-related data may include composite broadcast content and a hash table of the composite broadcast content. The storage management module 108 may manage input/output of broadcast content related data on the storage 110. That is, the storage management module 108 may serve to provide a control interface so that the broadcast content management apparatus 100 can manage duplicate content for broadcast content related data.

In the present specification, the term "module" may mean a functional and structural combination of hardware for performing the technical idea of the present invention and software for driving the hardware. For example, the "module" may mean a predetermined code and a logical unit of a hardware resource for executing the predetermined code, and does not necessarily mean a physically connected code or a single type of hardware.

According to the disclosed embodiment, by dividing broadcast content into unit blocks having a preset time, generating a hash value having a unique value in each unit block and storing it as a hash table, duplicate content inevitably occurring in the broadcast production process It is possible to introduce an efficient storage management method for the system, and to minimize the storage capacity of broadcast content.

The broadcast content is divided into unit blocks having a preset time, a hash value having a unique value is generated in each of the divided unit blocks, and a hash table is formed by matching the unit block and the hash value with respect to the broadcast content. A broadcast content structuring module to generate;
A storage storing the broadcast content and a hash table corresponding to the broadcast content;
A storage management module for managing input and output of the broadcast content and a hash table corresponding to the broadcast content to the storage; And
Including a broadcast content registration module for registering the broadcast content,
The broadcast content registration module,
If the same hash value exists in the hash table of the previously registered broadcast content among the hash values of the unit blocks of the broadcast content to be registered, the unit block corresponding to the hash value is not stored, and the broadcast content to be registered is A software definition-based broadcast content management apparatus that determines to store the unit block corresponding to the hash value when the same hash value does not exist in the hash table of the previously registered broadcast content among hash values of the unit blocks.
One or more processors, and
A method performed in a computing device having a memory storing one or more programs executed by the one or more processors,
Generating a composite broadcast content by tree-structuring the broadcast content;
Including the step of registering the composite broadcast content,
The step of generating the composite broadcast content,
Dividing the broadcast content into unit blocks having a preset time;
