This includes the infrastructure and platform of the execution environment on the edge of media services.

Cloud service (or cloud computing) is a technology that provides data services based on IT (Information Technology) resources virtualized on a network by using Internet technology. It is a concept technology that borrows and uses as many IT resources as necessary (process) and storage space.

Accordingly, the cloud service can rapidly process a large amount of data that cannot be accommodated at the resource level that a user actually possesses, and enables the use of a high performance / high speed data service based on the same.

In particular, data services are provided by providing an edge infrastructure (general-purpose H / W + FPGA / GPU acceleration infrastructure: general-purpose H / W) with an edge computing function at an edge near a user (terminal). A cloud service-based service distributed execution environment is provided that provides cloud services for a distributed network at an edge, which is a physical location closer to a user (terminal) than a core network and a core network.

Meanwhile, the media service sector is a representative service sector to which next generation mobile communication (eg 5G) is applied. There are various types of equipment that can be used by OTT providers that provide such media services, but most of them are located in the cloud or public cloud network behind cores that are self-configured. Therefore, service latency due to physical distance may exist. There is no choice but to. In addition, there is a need for an infrastructure and a platform capable of responding to an interactive situation rather than simply delivering media due to a cache service.

As shown in FIG. 1, the distributed cloud-based media service providing system according to the present invention basically provides a cloud service (or cloud computing) that realizes a data service based on information technology (IT) resources virtualized on a network. Is a system for providing

Cloud service (or cloud computing) is a technology that provides data services based on IT (Information Technology) resources virtualized on a network by using Internet technology. It is a concept technology that borrows and uses as many IT resources as necessary (process) and storage space.

Accordingly, the cloud service can rapidly process a large amount of data that cannot be accommodated at the resource level that a user actually possesses, and enables the use of a high performance / high speed data service based on the same.

In particular, the edge infrastructure (general-purpose hardware) with edge computing (Edge) near the user (terminal) is equipped with a computing function, so that the cloud service for data service is more user than the core network and core network. A cloud service based execution environment is provided, which is distributed at an edge, which is a physical location closer to the terminal.

On the other hand, since the data center related to the OTT service is located on the network behind the core, service latency due to the physical distance is inevitable.

Therefore, it is essential to support the infrastructure in the edge network for data services with high latency and low data latency such as Virtual Mobile Infrastructure (VMI), Virtual Reality (VR) / Augmented Reality. I can do it.

Accordingly, in the present invention, the cloud service for the specific service requested from the terminal is distributed in the edge (Edge) and the core network of the location close to the user (terminal) according to the properties of the specific service, and by providing the platform to enable In this paper, we propose a distributed cloud-based hybrid media service execution environment and platform.

Here, the specific service may be a media service or the like associated with the OTT service. Hereinafter, for convenience of description, the specific service will be described as a media service.

More specifically, the present invention proposes a distributed cloud-based media service providing system for realizing a distributed cloud-based hybrid media service execution environment.

Accordingly, FIG. 1 illustrates an embodiment of a distributed cloud-based media service providing system proposed by the present invention.

As shown in FIG. 1, the distributed cloud-based application execution system of the present invention is located in a core network and provides a core cloud node 200 and a terminal for providing a cloud service for a media service requested by the terminal 10. Located between the 10 and the core cloud node 200, when the terminal 10 is connected to allocate a service execution resource for the media service and selectively performs a specific function of the cloud service based on the service execution resource, Edge cloud node 100 for performing a cloud service for the data service with the core cloud node.

In the distributed cloud-based media service providing system of the present invention, there is a network device or network equipment involved in data transmission and reception between the edge cloud node 100 and the core cloud node 200, but for convenience of description The illustration is omitted.

In addition, in FIG. 1, one edge cloud node 100 is illustrated as one edge cloud node for distributing and providing one core cloud node 200 and cloud services. It is only.

That is, in the distributed cloud-based media service providing system of the present invention, one core cloud node 200 and a plurality of edge cloud nodes for distributing cloud services may be provided.

However, hereinafter, for convenience of description, one core cloud node 200 and one edge cloud node 100 will be described with reference.

The core cloud node 200 is located in the core network 1 and provides a cloud service (or cloud computing) that realizes a data service based on virtualized information technology (IT) resources.

Accordingly, the terminal 10 may use a data service based on a cloud service provided using an IT resource such as a function (process) of various arithmetic processing such as data classification, calculation, processing, and analysis, storage space, and the like.

In this case, the terminal 10 is a user-side device that can use the distributed cloud service provided by the distributed cloud-based media service providing system of the present invention, for example, a smartphone, a desktop PC, a tablet PC, a dedicated media service. Terminal and the like.

The terminal 10 may be a plurality (10a, 10b, 10c ...), may be a terminal of a user using a media service.

In order for the terminal 10a to access the edge cloud node 100 to use a cloud service (hereinafter, referred to as a distributed OTT service) for a media service, the terminal 10a subscribes to a distributed OTT service and receives information related to the terminal 10a. It would be desirable to register in advance.

The edgecloud node 100 also provides a cloud service (or cloud computing) that realizes data services based on virtualized information technology (IT) resources.

However, the edge cloud node 100 selectively performs a specific function (part of data processing processing) of the cloud service at a position closer to the terminal 10 side than the core cloud node 200, and the core cloud node 200. And distributed cloud services.

In detail, when the terminal 10 is connected, the edge cloud node 100 allocates execution resources for the media service requested from the terminal 10 and performs a specific function among data related to the media service based on the service execution resources. By selectively performing the data operation processing of the cloud service for the data service can be distributed with the core cloud node 200.

The edge cloud node 100, based on the storage node located in the base station 20 terminal that the terminal 10 is connected to the core network 1 for connection, core cloud node 200 and cloud services It is desirable to provide dispersion.

More specifically, for example, the edgecloud node 100 may include a mobile edge computing node located at the base station 20 end.

The mobile edge computing node (hereinafter referred to as MEC node) is a server-type node provided in the base station to store a large amount of data frequently used by the user or need for rapid transmission and to transmit the data immediately upon request.

Therefore, the MEC node implements storage for storing a large amount of data frequently used by the user or requiring fast transfer.

Thus, in the present invention, when the edge cloud node 100 is a node separate from the MEC node, the edge cloud node 100 provides a cloud service with the core cloud node 200 and the cloud service based on the storage node located at the base station 20, that is, the storage of the MEC node. Can provide dispersion.

In this case, the edge cloud node 100 is also preferably located at the base station 20 end.

Alternatively, in the present invention, when the edge cloud node 100 includes an MEC node, the edge cloud node 100 is based on a storage node located at the base station 20, that is, the storage that the core cloud node 200 and the cloud contain. You can also provide distributed services.

In this case, the edge cloud node 100 will be located at the base station 20 end.

Alternatively, in the present invention, the edge cloud node 100 may include or interoperate with a separate storage node separately from the MEC node, and provide a cloud service with the core cloud node 200 based on the storage node. You can also provide distributed.

Hereinafter, a detailed configuration of an edge cloud node (device) according to an embodiment of the present invention will be described with reference to FIG. 2. For convenience of description, reference numerals shown in FIG. 1 will be referred to, and the terminal will be described by referring to the terminal 10a.

First, when describing the edge cloud node 100 of the present invention, the edge cloud node 100, the terminal interworking unit 110 interoperating with the terminal 10a requesting the media service, the cloud in the access network for the media service A filtering unit 120 for selecting data related to a specific function of a service, a resource allocating unit 130 for allocating a service execution resource for a media service according to a specific function, and a filtering unit 120 based on the assigned service execution resource. And a service execution unit 140 performing a specific function of the cloud service on the media service by arithmetic processing of the data selected in step.

In this case, the filtering unit 120 transmits data other than data related to a specific function to a core cloud node, which is a service entity that provides a cloud service in the core network.

The edge cloud node 100 may further include a media engine pool 150 and a storage unit (cache) 160.

Before looking at the media engine pool 150, let's take a quick look at the edge infrastructure (general purpose hardware).

The edge infrastructure (general purpose hardware) provided in the edge cloud node 100 includes a field-programmable gate array (FPGA) card dedicated to processing capable of resetting process functions, and a high-speed computational GPU (Graphic Processing Unit). Card, and the like.

Thus, if a portion of such resources, such as FPGA card, GPU card of the edge infrastructure (general purpose H / W) is allocated for the distributed OTT service of the present invention, it is possible to implement a media platform on the edge cloud node 100 do.

As such, the media platform implemented on the edgecloud node 100 includes a media infrastructure accelerator for transcoding and streaming, a traffic offload accelerator for core traffic offload control, and a core cloud. A cache for storing media originals and the like related to the media service copied from the node 200 is provided.

In order to facilitate the functioning of the media platform having such a configuration, related engines should be provided. The set of engines may be a media engine pool 150.

That is, the media engine pool 150 may include a media processing engine, a media caching engine, a media / offload acceleration engine, and a VMI engine. Infrastructure Engine), VDI Engine (Virtual Desktop Infrastructure Engine), and the like.

In this case, resource-related information indicating how much resources are required to operate the engine is mapped to each engine in the media engine pool 150.

Accordingly, when the media service is requested from the terminal 10a and data related to a specific function is selected from the data related to the media service, the resource allocator 130 selects data related to the specific function from the media engine pool 150. By checking the resource-related information of the media engine to perform the operation processing for the service allocation resources can be allocated, a detailed description will be described later.

The terminal interlocking unit 110 is a functional unit that interworks with the terminal 10a requesting a media service.

That is, when the terminal interworking unit 110 requests access to the edge cloud node 100, the terminal interworking unit 110 determines whether to interwork by checking whether the terminal 10a is subscribed to the distributed OTT service.

As mentioned in the foregoing description, if the terminal 10a is subscribed to the distributed OTT service, information related to the terminal 10a will be registered in the edge cloud node 100.

Accordingly, the terminal interlocking unit 110 may determine whether to interlock based on the information related to the pre-stored terminal 10a.

When interworking with the terminal 10a according to the above, the terminal interlocking unit 110 receives data related to a media service (eg, media processing, media play, etc.) from the terminal 10a and transmits the data to the terminal 10. Example: The result of data operation processing related to a specific function of the media service) can be transmitted.

The filtering unit 120 selects data related to a specific function of a cloud service provided for the media service, from among data related to the media service requested by the terminal 10a, and other data is transmitted from the core network 1 stage. It delivers to the core cloud node 200, which is a service principal that provides a cloud service.

At this time, the data related to the media service, the user using the distributed OTT service performs a function (media generation, media update, transcoding, overlay, streaming / playback, etc.) desired to be provided through the media platform in the edge cloud node 100 It may be data associated with the request.

Accordingly, the filtering unit 120 may check a corresponding function that a user who uses a distributed OTT service wants to receive from data related to a media service.

When the user of the distributed OTT service checks the corresponding function to be provided according to the above, the filtering unit 120 determines that the user using the distributed OTT service receives the corresponding function, that is, the data related to the media service. Select the data related to the function.

In this case, the specific function may be determined according to the property of the media service. Here, the attribute of the media service may be defined as an ultra low delay data service, a large data service, etc., but for convenience of description, the description will be continued by referring to it as an ultra low delay data service.

That is, the specific function may be a function of real-time guarantee or a fast service speed among cloud service functions provided for the media service requested from the terminal. Hereinafter, for convenience of description, specific functions are transcoding, overlay, streaming / playback, and other media creation and media update will be referred to as other functions.

Accordingly, the filtering unit 120 filters (selects) data of a specific function related to the ultra low delay data service among data related to the media service, and transfers other data to the core cloud node 200 of the core network 1. do.

For example, when the data related to the media service is data requesting to perform functions of transcoding, overlaying, streaming / playing, media generation, and media updating, the filtering unit 120 may determine transcoding, overlaying, streaming / playing. Only the data is filtered (selected) with data related to a specific function, and other data, such as media creation and media update, are transmitted to the core network 1.

In this case, data related to the other functions that are delivered to the core cloud node 200 without being filtered by the edge cloud node 100 are based on the user context in the core cloud node 200 that interworks with the big data (storage node). Will be processed.

Thus, the core cloud node 200, the storage node for interlocking or interlocking the data operation processing result of the calculation processing based on the resources allocated to the user using the distributed OTT service of the terminal 10a based on the user context. Stored in the terminal, based on the user context of the terminal 10a to provide (deliver) to the terminal 10a through the edge cloud node 100, it is possible to provide a user context-based cloud service.

The resource allocation unit 130 allocates a service execution resource for the media service according to a specific function.

More specifically, when the filtering (selection) of the data related to a specific function is completed from the filtering unit 120, the resource allocator 130 determines a service based on a result of identifying a media engine to perform arithmetic processing on a specific function. Allocate execution resources.

At this time, as mentioned in the foregoing description, resource related information indicating how much resources are required to operate the engine is mapped to the media engine to perform the operation processing on the specific function.

Thus, if the resource allocator 130 identifies the media engine to perform the operation processing for the specific function, the resource allocation unit 130 may allocate the service execution resource based on the resource related information mapped to the media engine.

As such, identifying the media engine to perform arithmetic processing for a specific function when allocating service execution resources may include limited computing resources for processing data operations allocated by the edgecloud node 100 to perform a media platform function. In order to improve resource utilization efficiency by allocating service execution resources according to the result of checking the amount of resources required for the media engine to operate.

Meanwhile, in the above description, the service execution resource is allocated based on the resource related information mapped to the media engine. However, the present invention is not limited thereto, and the service execution resource may be allocated in consideration of resource related information and data size. Of course. That is, in the present invention, the service execution resource may be allocated in various ways according to the setting of the operator.

The service execution unit 140 performs a specific function of the cloud service on the media service by processing the data selected by the filtering unit 120 based on the service execution resource allocated by the resource allocator 130.

That is, the service execution unit 140 checks a specific function selected by the filtering unit 120, and then selects a media engine necessary for arithmetic processing of a specific function from the media engine pool 150 to perform arithmetic processing.

First, a process of performing arithmetic processing when a specific function is a function for media processing on data related to a media service will be described.

If the specific function is a function for media processing on data related to the media service, the service execution unit 140 performs arithmetic processing for processing data related to the media service.

For example, if a media service is requested from the terminal 10a and a function for media processing is selected as a specific function from the data related to the media service from the filtering unit 120, the service execution unit 140 includes a media engine pool. The media processing engine of the pool 150 is called.

Thereafter, the service execution unit 140 generates a first calculation processing result by performing arithmetic processing of transcoding data related to a specific function using a media processing engine.

Subsequently, the service execution unit 140 calls the media caching engine of the media engine pool 150.

Thereafter, the service execution unit 140 stores the result of performing the first operation processing in the storage unit (cache) 160 using the media caching engine, and transfers it to the core cloud node 200 to share it.

Next, a process of performing arithmetic processing when a specific function is a function for media play will be described.

If the specific function is a function for media play, the service execution unit 140 performs a calculation process for media play based on a result of checking whether a media original associated with the media service exists.

For example, if a media service is requested from the terminal 10a, and a function for media play is selected as a specific function from the data related to the media service from the filtering unit 120, the service execution unit 140 is a media engine pool. The media caching engine of (Pool) 150 is called.

Thereafter, the service execution unit 140 checks whether or not the media original to be played in the storage unit (cache) 160 using the media caching engine.

If the media source related to the media service exists in the storage unit (cache) 160, the service execution unit 140 may perform a media / offload acceleration engine (Media / Offload) of the media engine pool (150). Acceleration Engine).

Thereafter, the service execution unit 140 generates a second calculation processing result by performing arithmetic processing so that the media original is played (accelerated) using the media / offload acceleration engine.

On the other hand, if a media source related to the media service does not exist in the storage unit (cache) 160, the service execution unit 140 copies and stores the media source from the corecloud node 200 using the media caching engine. Store in the cache (160).

Thereafter, the service execution unit 140 generates a second calculation processing result by performing arithmetic processing so that the media original is played (accelerated) using the media / offload acceleration engine as described above.

Next, a process of performing arithmetic processing when a specific function is a function requiring additional data in addition to the data related to the media service will be described.

When the specific function is a function requiring additional data other than the data related to the media service, the service execution unit 140 overlays an operation based on a result of checking whether a media source related to the media service exists. Perform

In the following description, for convenience of description, a specific function is to perform a media play associated with virtual reality (AR) / augmented reality (AR), and the virtual reality (VR) / augmentation on the media source. It will be described by mentioning that separate data for reality (AR) should be overlaid.

That is, the media service is requested from the terminal 10a to perform the virtual reality (VR) / augmented reality (AR) related media play among the data related to the media service from the filtering unit 120, but the virtual reality (VR) / augmented reality If a function to which the separate data for AR is to be overlayed is selected as a specific function, the service execution unit 140 calls the media caching engine of the media engine pool 150. .

Thereafter, the service execution unit 140 checks whether a virtual reality (VR) / reinforcement reality (AR) related media original to be played using the media caching engine exists in the storage unit (cache) 160.

As a result of the check, if the VR / AR related media original exists in the storage unit (cache) 160, the service execution unit 140 may be configured to overlay other data to be overlaid using the media caching engine. The original is copied from the core cloud node 200 and stored in the storage unit (cache) 160.

Thereafter, the service execution unit 140 calls a media processing engine and a media / offload acceleration engine of the media engine pool 150.

Subsequently, the service execution unit 140 uses the media processing engine and the media / offload acceleration engine to receive other data received from the corecloud node 200 on the virtual reality (VR) / augmented reality (AR) related media source. Compute the third operation processing result by performing the operation processing to overlay the original of the.

On the other hand, if the virtual reality (VR) / augmented reality (AR) related media original does not exist in the storage unit (cache) 160, the service execution unit 140, the core cloud node 200 using the media caching engine Copy the virtual reality (VR) / augmented reality (AR) -related media original and other data from the original storage unit (cache) (160).

Thereafter, the service execution unit 140 overlays the original data of other data on the virtual reality (VR) / augmented reality (AR) related media source using the media processing engine and the media / offload acceleration engine as described above. The calculation process is performed to generate a third calculation processing result.

In the above description, although a specific function is referred to as performing a media play related to virtual reality (VR) / augmented reality (AR), the media play related to virtual mobile infrastructure (VMI) / virtual desktop infrastructure (VDI), etc. In the case of performing (Media Play), the operation may be performed by overlaying operations using a VMI engine, a VDI engine, or the like in the same manner.

On the other hand, it is preferable that all the above-mentioned operation processing performed in the above-mentioned operation is performed based on the service execution resources allocated by the resource allocator 130, and more service execution resources are required than those previously allocated in the operation processing. In this case, of course, the resource allocation unit 130 may further request a resource or may be performed / distributed in the core cloud node 200.

According to the operation method of the edge cloud node 100 of the present invention, when the terminal 10a requests access to the edge cloud node 100, it is determined whether or not interworking by checking whether or not subscribed to the distributed OTT service.

That is, the edge cloud node 100 allows the terminal 10a to access the terminal 10a based on previously stored information related to the terminal 10a, and receives data related to the media service from the terminal 10a (S100).

Then, according to the operation method of the edge cloud node 100 of the present invention, among the data related to the media service requested by the terminal 10a, select data related to a specific function of the cloud service provided for the media service, The other data is transferred to the core cloud node 200, which is a service entity that provides a cloud service in the core network 1 stage (S101).

At this time, the data related to the media service, the user using the distributed OTT service performs a function (media generation, media update, transcoding, overlay, streaming / playback, etc.) desired to be provided through the media platform in the edge cloud node 100 It may be data associated with the request.

Accordingly, the edge cloud node 100 may check a corresponding function that a user who uses a distributed OTT service wants to receive from data related to a media service.

When the user of the distributed OTT service checks the corresponding function to be provided in accordance with the above, the edge cloud node 100 receives the corresponding function, i.e., data related to the media service, that the user using the distributed OTT service wants to receive. Select data related to a specific function.

In this case, the specific function may be determined according to the property of the media service. Here, the attributes of the MIDI service may be defined as an ultra low delay data service or a large data service, but for convenience of description, the description will be continued by referring to the ultra low delay data service.

That is, the specific function may be a function of real-time guarantee or a fast service speed among cloud service functions provided for the media service requested from the terminal. Hereinafter, for convenience of description, specific functions are transcoding, overlay, streaming / playback, and other media creation and media update will be referred to as other functions.

Accordingly, according to the operation method of the edge cloud node 100 of the present invention, the data of a specific function related to the ultra-low delay data service among the data related to the media service is filtered (selected), and the other data is stored in the core network 1. The core cloud node 200 may be delivered to the core cloud node 200.

For example, when the data related to the media service is data requesting to perform functions of transcoding, overlaying, streaming / playing, media generation, and media updating, the filtering unit 120 may determine transcoding, overlaying, streaming / playing. Only the data is filtered (selected) with data related to a specific function, and other data, such as media creation and media update, are transmitted to the core network 1.

When the filtering (selection) of data related to a specific function is completed according to the above, the edge cloud node 100 allocates a service execution resource based on a result of identifying a media engine to perform arithmetic processing on a specific function (S102). ).

At this time, as mentioned in the foregoing description, resource related information indicating how much resources are required to operate the engine is mapped to the media engine to perform the operation processing on the specific function.

Thus, if the edge cloud node 100 identifies a media engine to perform arithmetic processing for a specific function, the edge cloud node 100 may allocate service execution resources based on resource related information mapped to the media engine.

Meanwhile, in the above description, the service execution resource is allocated based on the resource related information mapped to the media engine. However, the present invention is not limited thereto, and the service execution resource may be allocated in consideration of resource related information and data size. Of course. That is, in the present invention, the service execution resource may be allocated in various ways according to the setting of the operator.

Then, according to the operation method of the edge cloud node 100 of the present invention, the data processing associated with a specific function based on the service execution resources.

For example, when a specific function is a function for media processing (Media Processing) for data related to the media service (YES in S103), according to the operation method of the edgecloud node 100 of the present invention, the data related to the media service Arithmetic processing for processing is performed (S104, S105).

That is, when a mediar service is requested from the terminal 10a and a function for media processing is selected as a specific function among data related to the media service, the edge cloud node 100 uses the media processing engine to transmit data related to the specific function. The first operation processing result is generated by performing arithmetic processing of transcoding.

Subsequently, the edge cloud node 100 stores the result of performing the first operation processing in the storage unit (cache) 160 using the media caching engine, and transfers the shared result to the core cloud node 200.

As another example, when a specific function is a function for media play (YES in S106), according to the operation method of the edgecloud node 100 of the present invention, based on a result of checking whether a media original associated with a media service exists. Arithmetic processing for media play is performed (S107, S108).

That is, when a mediar service is requested from the terminal 10a and a function for media play is selected as a specific function among data related to the media service, the edgecloud node 100 may select a media source to be played using the media caching engine. It is checked whether or not the storage unit (cache) 160 exists.

If the media source related to the media service exists in the storage unit (cache) 160, the edgecloud node 100 processes the media source to be played (accelerated) by using the media / offload acceleration engine. Generates a second operation processing result.

On the other hand, if the media source associated with the media service does not exist in the storage unit (cache) 160, the edgecloud node 100 copies and stores the media source from the corecloud node 200 using the media caching engine. Store in the cache (160).

Subsequently, the edge cloud node 100 generates a second calculation processing result by performing a calculation process such that the media original is played (accelerated) using the media / offload acceleration engine as described above.

As another example, when a specific function is a function requiring additional data other than data related to the media service (S109), according to the operation method of the edgecloud node 100 of the present invention, is there a media source related to the media service? Based on the result of checking whether or not, an operation process of overlaying is performed (S110 and S111).

In the following description, for convenience of description, a specific function is to perform a media play associated with virtual reality (AR) / augmented reality (AR), and the virtual reality (VR) / augmentation on the media source. It will be described by mentioning that separate data for reality (AR) should be overlaid.

That is, the media service is requested from the terminal 10a to perform a virtual reality (VR) / augmented reality (AR) related media play of the data related to the media service, but separate for the virtual reality (VR) / augmented reality (AR) If the function that should be overlaid with other data is selected as a specific function, the edgecloud node 100 is configured to store a cache (cache) related to the virtual reality (VR) / augmented reality (AR) media to be played using the media caching engine. Check whether or not there is 160).

If the virtual reality (VR) / augmented reality (AR) -related media source exists in the storage unit (cache) 160, the edge cloud node 100, the core cloud node 200 using the media caching engine Copy and store the original of the other data to be overlaid from the storage unit (cache) 160.

The edgecloud node 100 then uses the media processing engine and media / offload acceleration engine to receive other data received from the corecloud node 200 on the virtual reality (VR) / augmented reality (AR) related media source. Compute the third operation processing result by performing the operation processing to overlay the original of the.

On the other hand, if the virtual reality (VR) / augmented reality (AR) related media original does not exist in the storage unit (cache) 160, the edge cloud node 100, the core cloud node 200 using the media caching engine Copy the virtual reality (VR) / augmented reality (AR) related media originals and other originals of the data and stores in the storage unit (cache) (160).

Thereafter, the edgecloud node 100 overlays the source of other data on the virtual reality (VR) / augmented reality (AR) related media source using the media processing engine and the media / offload acceleration engine as described above. The calculation process is performed to generate a third calculation processing result.

In the above description, although a specific function is referred to as performing a media play related to virtual reality (VR) / augmented reality (AR), the media play related to virtual mobile infrastructure (VMI) / virtual desktop infrastructure (VDI), etc. In the case of performing (Media Play), the operation may be performed by overlaying operations using a VMI engine, a VDI engine, or the like in the same manner.
