That is, the cloud streaming server executes an application on the server side, captures and encodes a screen corresponding to the execution result, and sends the resultant message to the terminal, and the execution result is streamed to the terminal .

Because cloud-streaming servers share resources among multiple users, resource utilization management is a very important issue.

When a single application is executed in the cloud streaming server, a section in which a resource utilization rate is actually high when executing the application is often a predetermined section in an application execution section, and the length of the specific section is often short. Even in this case, if the system resources of the server are insufficient in this particular interval, the operation of the cloud streaming system becomes unstable and may affect other users. Therefore, the cloud streaming server can not execute the maximum number of applications .

For example, if an application is run through the cloud streaming service, the average CPU utilization is about 5%. However, if the CPU usage rate is 30% for a specific interval, the number of applications must be limited to a certain interval. It becomes unusable.

In particular, the cloud streaming server must perform a streaming pipeline procedure of rendering, capturing, encoding, and sending every screen refresh cycle, It is very important to use it efficiently.

Furthermore, there are applications that use system resources in a predetermined order among applications. In such an application, a section that uses a lot of system resources is determined.

Therefore, there is an urgent need for a new cloud streaming service technology capable of efficiently managing the system resources of the cloud streaming server when an application having a high resource usage is executed only in a specific section.

1 is a block diagram illustrating a cloud streaming service system according to an embodiment of the present invention.

1, a cloud streaming service system according to an embodiment of the present invention includes a cloud streaming server 110, terminals 120-1 to 120-N, and a network 130. [

The cloud streaming server 110 executes an application corresponding to a request of any one of the terminals 120-1 to 120-N and transmits an application execution result screen corresponding to the application execution result to the terminals 120 -1, ..., 120-N. At this time, the application execution result screen may be generated by performing a streaming pipeline procedure of capturing, encoding, and sending in the cloud streaming server every screen refresh period. Streaming pipeline procedures can be viewed as consisting of rendering, capturing, encoding and sending, including rendering.

Hereinafter, the screen update period may be the time required for updating the screen or the number of times the screen is updated for one second. For example, the unit of the refresh cycle may be s or 1 / s.

The cloud streaming server 110 stores a section clip in which an execution screen corresponding to a predetermined execution section of the application is rendered and determines the use condition of the section clip in consideration of the execution state of the application executed for the cloud streaming service.

At this time, if it is determined that the use condition of the interval clip is not satisfied, the cloud streaming server 110 performs a normal streaming procedure of rendering, capture, encoding, and sending for each screen update cycle .

At this time, the cloud streaming server 110 performs a shortened streaming procedure for sending the interval clip if it is determined that the use condition of the interval clip is satisfied.

In this manner, the cloud streaming server 110 can selectively use the server resources by selectively performing the normal streaming procedure or the shortened streaming procedure according to whether the use condition of the interval clip satisfies the condition.

That is, in many cases, a lot of system resources are required only in a certain section determined for each application, and in such a case, the number of applications executed in the server is limited due to a corresponding section requiring a lot of system resources.

According to the present invention, a section clip corresponding to a certain section requiring a large amount of system resources is generated in advance, and a short section for directly transmitting a section clip instead of the normal streaming procedure of rendering, capturing, By executing the streaming procedure, more cloud streaming applications can be executed under a predetermined system resource.

For example, if the total duration of the fairy tale reading application is 5 minutes and the average CPU utilization is 5% but the CPU utilization is 30% for the first 30 seconds after the application starts, the maximum application that can be reliably serviced by the server The number is two or three. However, when the present invention is applied, a section clip corresponding to a corresponding section (for the first 30 seconds) is generated, and if the section clip generated at the execution of the corresponding section of the application is directly sent, the normal streaming procedure is performed in the corresponding section And consumes far less resources. For example, if you send segment clips directly for the first 30 seconds after the application starts, if the CPU usage is 10%, the maximum number of applications that can be reliably serviced is increased to 7 ~ 8.

The terminals 120-1,..., 120-N receive an application execution result screen corresponding to the cloud streaming service from the cloud streaming server 110 and provide them to the user.

Each of the terminals 120-1 to 120-N is connected to a communication network and is capable of executing an application based on a cloud computing system. The terminal 120-1 is not limited to a mobile communication terminal, A wired terminal, a fixed terminal, and an IP (Internet Protocol) terminal. Each of the terminals 120-1 to 120-N may be a cellular phone, a PMP (Portable Multimedia Player), a MID (Mobile Internet Device), a smart phone, a desktop, A mobile terminal having various mobile communication specifications such as a tablet PC, a notebook computer, a net book, a personal digital assistant (PDA), a smart TV, and an information communication device .

The network 130 provides a pathway for communicating data between the cloud streaming server 110 and the terminals 120-1, ..., 120-N, It is a comprehensive concept. For example, the network 130 may be a wired or wireless local area network that provides communication of various information devices within a limited area, a mobile communication network that provides communication between mobile objects and mobile objects outside the mobile object, Or a wired / wireless communication network, or a combination of two or more. Meanwhile, the transmission scheme standard of the network 130 is not limited to the existing transmission scheme standard, and may include all transmission scheme standards to be developed in the future. 1, the network used between the cloud streaming server 110 and the terminals 120-1, ..., and 120-N is located between the terminals 120-1, ..., Or may be the same.

2 is a block diagram illustrating an example of the cloud streaming server shown in FIG.

Referring to FIG. 2, the cloud streaming server shown in FIG. 1 includes a communication unit 210, a storage unit 220, and a control unit 230.

The storage unit 220 stores a section clip in which an execution screen corresponding to a predetermined execution section of the application is rendered.

At this time, the interval clip may be generated by performing rendering, capturing, and encoding during the execution interval.

In this case, the interval clip may be generated for a period in which the corresponding application is executed in advance and resources of the cloud streaming server are used over a predetermined level.

At this time, the section clip may be generated in accordance with the quality assurance (QA) of the application. Generally, an application for a cloud streaming service is subjected to a quality management step. Therefore, in a quality management step, a section is generated by performing rendering, capturing, and encoding for a specific section having a high resource utilization rate in advance, It can be used to manage resource usage and to lower resource usage when running applications.

At this time, the execution period can be set to the same for the same application. In other words, if the same moving image reading application is used, the section with high resource usage will be the same, so it is not necessary to check again the execution section with high resource use rate for the same application.

At this time, the execution period can be set independently for each application. That is, since a high resource utilization rate is different for each application, an interval suitable for the application should be set as an execution interval to generate a section clip.

The control unit 230 determines whether the use condition of the clip is satisfied by considering the execution state of the application executed for the cloud streaming service. If it is determined that the use condition of the section clip is not satisfied, the controller 230 performs rendering, capturing, encoding, and normal streaming procedures for each screen update cycle.

If it is determined that the use condition of the interval clip is satisfied, the control unit 230 performs the unicast streaming procedure of transmitting the interval clip.

The control unit 230 selectively performs the normal streaming procedure or the shortened streaming procedure to minimize the influence of the period even if the resource usage rate of a certain section is high so as to provide the cloud streaming service to the terminal while using the server resources more efficiently .

At this time, the shortened streaming procedure may be to use fewer cloud streaming server resources than the normal streaming procedure.

In this case, the use condition of the section clip may be whether or not the execution timing of the application belongs to a predetermined section. That is, the interval clip is generated for a predetermined application execution interval, and when the application execution timing reaches this interval, the control unit can determine that the interval clip use condition is satisfied.

The communication unit 230 transmits and receives information related to a plurality of terminals through a communication network such as the network shown in FIG. In particular, the communication unit 230 according to the embodiment of the present invention receives a request for the cloud streaming service from the terminal, and provides an execution result screen of the application corresponding to the cloud streaming service requested by the terminal to the terminal.

The storage unit 220 stores various information generated in the cloud streaming service process according to the embodiment of the present invention in addition to the section clips.

According to an embodiment, the storage unit 220 may be configured independently of the cloud streaming server 110 to support a function for the cloud streaming service. At this time, the storage unit 220 may operate as a separate mass storage and may include a control function for performing operations.

In addition, the cloud streaming server 110 configured as described above may be implemented as one or more servers.

On the other hand, the cloud streaming server 110 is loaded with a memory and can store information in the device. In one implementation, the memory is a computer-readable medium. In one implementation, the memory may be a volatile memory unit, and in other embodiments, the memory may be a non-volatile memory unit. In one implementation, the storage device is a computer-readable medium. In various different implementations, the storage device may comprise, for example, a hard disk device, an optical disk device, or any other mass storage device.

3 is a block diagram showing an example of the control unit shown in FIG.

Referring to FIG. 3, the control unit illustrated in FIG. 2 includes a determination unit 310, a normal procedure execution unit 320, and a resource saving mode unit 330.

The determination unit 310 determines whether the use condition of the section clip is satisfied. In this case, the use condition of the interval clip may be whether or not the execution timing of the application has reached a preset interval. For example, if this resource utilization rate is set to the highest execution interval from 5 minutes to 30 seconds after the execution of the assimilation reading application, the usage condition of the interval clip is 5 minutes to 5 minutes 30 seconds after the assimilation reading application starts ≪ / RTI >

The normal procedure performing unit 320 performs a normal streaming procedure of rendering, capturing, encoding, and sending.

The resource saving mode unit 330 performs the unicast streaming procedure for transmitting the interval clip. At this time, the shortened streaming procedure is less resource consuming than the normal streaming procedure of rendering, capturing, encoding, and sending since it only transmits the section clip in which rendering, capturing, and encoding are performed.

FIG. 4 is a graph showing a change in resource utilization rate of an application having a high resource utilization rate only in a certain section.

Referring to FIG. 4, it can be seen that the resource usage rate according to the execution time of the application is known, and that the interval in which the resource usage rate exceeds 30% is the interval A and the interval B, respectively.

Generally, when a cloud streaming service is provided, the application will run two applications because the resource utilization reaches 50% (when normal streaming procedure is performed) in a certain section (section A).

The present invention is applied to generate a section clip corresponding to section A and section B, and the section clip is transmitted without performing the normal streaming process of rendering, capturing, encoding, and sending in section A and section B, If the resource utilization is less than 30%), the server will be able to run three applications without problems.

The execution intervals, such as A and B, may be set differently for different applications. However, the execution period may be set the same for the same application.
