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

Referring to FIG. 1, a system for providing a cloud streaming service according to an embodiment of the present invention includes a user device 100, a service device 200, and a communication network 300.

Basically, the user apparatus 100 and the service apparatus 200 communicate with each other via the communication network 300. [ The communication network 300 is a communication network accessible by the user apparatus 100, and is not necessarily limited thereto, but is preferably an IP-based network. An IP-based network can represent the Internet as an example. The communication network 300 may be a wireless communication system such as a WLAN (Wireless LAN), a Wi-Fi, a Wibro, a WiMAX, or a High Speed Downlink Packet Access (HSDPA) (ADSL, VDSL), Hybrid Fiber Coaxial Cable (HFC), Fiber to the Curb (FTTC), and Fiber To The Home (FTTH). Hereinafter, it is assumed that the network is an IP-based network.

The user device 100 is a terminal device of a user using a cloud streaming service. The user device 100 accesses the service device 200 through the communication network 300 to request a cloud streaming service for a specific application, And outputs the result to the user. Here, the service request may be transmitted including at least one of an execution request for a specific application, a user input related to a specific application, and the like. In particular, the user device 100 receives an execution screen of a specific application requested by the user from the service device 200 as an execution result, and outputs the execution screen to the user, so that the specific application performs a user experience similar to that executed in the user device 100 To the user.

The service device 200 is a configuration for providing a cloud streaming service for one or more applications to the user device 100 through the communication network 300. Specifically, the service device 200 stores one or more applications, executes a specific application requested by the user device 100 in accordance with a service request from the user device 100, To the device 100 so that the application or service can be made available to the user even if the user device 100 can not execute the application. Such a cloud streaming service may representatively transmit a specific video content through a video player and then transmit the playback screen to the user device 100. As another example, after the service device 200 executes a specific game application according to the user input transmitted from the user device 100, the execution screen is streamed to the user device 100, So that the user can be provided with the experience of playing the game through the game machine 100. In the present invention, the term " streaming service " is representative of providing moving pictures in real time as illustrated, for example. However, the " streaming service " is not necessarily restricted to services transmitted from the service device 200 to the user device 100 without interruption. Data may be discontinuously generated by the interaction between the user device 100 and the service device 200 or by the service device 200 and the service device 200 may generate data discontinuously generated To the user device 100 in real time. As described above, according to the embodiment of the present invention, all services provided in real time with data are included in the category of " streaming service ". For example, if the service device 200 is assumed to be a server that services the game application on a cloud streaming basis, the input for the user to perform the game operation may be discontinuous and the user device 100 The service device 200 can generate data in real time and provide it to the user device 100 in real time by the input transmitted to the service device 200. [ As another example, the service device 200 executes a document editor, which is an application on the service device 200 in a cloud computing environment, and provides a document, which is a content to be edited and an interface of a text editor I suppose. Even in this case, the input by the user through the interface of the document editor may be discontinuous, and the input by the user device 100 to the service device 200 by the discontinuous input causes the service device 200 to transmit the document in real time Edit, and provide data generated thereby to the user device 100 in real time.

The service device 100 stores one or more applications that are objects of the cloud streaming service described above in a predetermined storage means (referred to as a service storage unit), loads the application from the service storage unit according to a service request of the user, And executes the application according to the input to provide the execution result to the user device 100.

Here, the loading state means that the binary data of the application is read from the service storage unit to the system memory, and the user is able to receive the user input. Then, when the service of the user device 100 for the first application is requested, the service device 100 executes the first application that is currently being loaded, without loading, according to user input and transmits the execution result to the user device 100 100). For this, the service device 100 may set one or more first applications to be preloaded, and in particular, may set a first application based on at least one of a data size, an arithmetic amount, and a user requested latency. The user requested latency is a minimum waiting time allowed according to the characteristics of the application, and can be arbitrarily set for each application. For example, in the case of a UI application, the user requested latency may be shorter than the game application.

According to one embodiment, the first application may be an application having a data size less than a preset value. According to another embodiment, the first application may be an application having a user requested latency less than a preset value.

Since the storage capacity of the service device 200 is limited, it is difficult to preload and provide all the data. Accordingly, the service apparatus 200 can set at least one first application to be preloaded among a plurality of applications in consideration of the storage capacity and the load. For example, an application having a small memory capacity and a low user requested latency such as a UI (User Interface) application may be set as a first application and preloaded, As a result, the response speed is increased to provide the user with satisfaction and at the same time, the service apparatus 200 can be efficiently used.

4 is a flowchart illustrating a method for providing a cloud streaming service according to an embodiment of the present invention.

Referring to FIG. 4, the service device 200 stores a plurality of applications to be served to a user in the service storage 220, and in particular, the plurality of applications include one or more first applications set in advance.

At this time, in step S105, the service apparatus 200 determines whether or not a service request from the user apparatus 100 is received, regardless of a service request from the user apparatus 100, The first application is fetched and loaded into the system memory of the service control unit 230 so that the first application is ready to receive user input for the first application.

Meanwhile, the user device 100 can access the service device 200 at the request of the user. Such a connection may be through a so-called " log-in " procedure for identifying a user of the user device 100 or the user device 100. Therefore, in this connection process, the user device 100 transmits an identifier for identifying the user or the user device 100, and the service device 200 can proceed to authenticate the identifier. The service device 200 can identify the user device 100 or the user connected thereto.

As described above, the user apparatus 100 connected to the service apparatus 200 can transmit the service request message for the first application to the service apparatus 200 in step S110.

Upon receiving the service request message of the user device 100, the service device 200 executes the first application that is preloaded in step S115 according to the user input, and transmits the execution result to the user device 100 in step S120 to provide. More specifically, the service apparatus 200 can code the execution screen of the first application and transmit it to the user apparatus 100 in a streaming manner in real time. The user device 100 decodes the execution screen received in step S125 and outputs the decoded execution screen to the display unit 120 so that the user can receive the execution result of the application. Here, since the first application is in a state of being loaded in advance, the time t1 required for receiving the execution result of the requested first application after providing the service in the user device 100 and providing it to the user is shortened by the time required for loading .

On the other hand, the user device 100 may access the service device 200 and request a service for an application other than the first application.

That is, in step S130, the user device 100 generates a request message for requesting a cloud streaming service for an application other than the first application (hereinafter, referred to as a second application) according to user input, Lt; / RTI >

After receiving the service request message, the service device 200 checks the requested second application by referring to the received request message in step S130, and then, in step S135, selects the second application from among the plurality of applications stored in the service storage 220 And loads it into the system memory of the service control unit 230.

If the loading of the second application is completed and the second application can receive the user input, the service apparatus 200 executes the second application loaded in step S140 according to user input, and executes the second application in step S145 And transmits the result to the user device 100. More specifically, as described above, the execution screen of the second application is encoded and transmitted to the user device 100 in a streaming manner.

Here, the user requested latency can be arbitrarily set for each application as a minimum latency allowed according to the characteristics of the application. For example, in the case of a UI application, the user requested latency may be shorter than the game application. According to an embodiment of the present invention, the first application may be set as an application having a data size less than a preset value and having a user requested latency less than a predetermined value. In other words, since the storage capacity of the service device 200 is limited, it is difficult to preload and provide all the data. Accordingly, the service apparatus 200 can set at least one first application to be preloaded among a plurality of applications in consideration of the storage capacity and the load. For example, an application having a small occupation capacity of memory such as a UI (User Interface) application and a low user requested latency can be set as the first application.

When the first application is set up, the service device 200 reads one or more first applications from among a plurality of applications stored in the service storage 220 in step S220, Lt; / RTI > The loaded first application is ready to receive user input. In addition, the loading of the first application is preferably performed before the service request for the first application of the user device 100, irrespective of the service request of the user device 100.

Then, in step S230, the service device 200 may receive a service request for a specific application from the user device 100. [ The service request is a service request related to the cloud streaming service. The request message may include at least one of a user identifier and a user equipment identifier. In addition, the request message may further include at least one of an application identifier and a content identifier. In addition, the service device 200 may perform a connection to the user device 100 before receiving the service request. This connection may be a so-called " log-in " procedure for identifying a user of the user device 100 or a user of the user device 100, The service control unit 230 receives the identifier through the service communication unit 210, authenticates the received identifier, and identifies and detects the user device 100 or the user connected thereto . ≪ / RTI >

Referring again to FIG. 5, the service device 200 receiving the service request of the user device 100 can confirm whether the service request is a service request for the first application in step S240.

As a result of checking, if the service request for the first application is received, the service device 200 executes the already loaded first application in accordance with the user input in step S250, and in step S260, To the device (100).

On the other hand, if it is determined in step S240 that the requested application is not the first application, the service device 200 reads the requested application from the service storage unit 220 through step S270, Load into memory.

Then, the service device 200 executes the loaded application according to the user's input through steps S250 and S260, and transmits the execution result to the user device 100, like the first application.
