4 is a data flow chart for explaining a data transmission method based on cloud streaming according to an embodiment of the present invention.

Referring to FIG. 4, the client terminal 10 for data transmission based on the cloud streaming according to the present invention requests execution of the cloud streaming-based application to the service device 20 in step S11. When the service device 20 is requested to execute the application based on the cloud streaming from the client terminal 10 in step S13, the service device 20 requests the maximum capacity of the buffer memory and system environment information to the client terminal 10. [ Here, the capacity of the buffer memory is determined according to the characteristics of the client terminal 10, and the system environment information includes the operating system capacity of the client terminal 10, RAM, screen size, resolution, supportable input signals, Camera pixels, and the like.

The client terminal 10 collects the maximum capacity of the buffer memory and the system environment information, and transmits the collected information to the service apparatus 20 (S15 to S17). Then, the service device 20 confirms the information received from the client terminal 10 in step S19.

The service device 20 executes the corresponding application according to the maximum capacity of the buffer memory and the system environment information received from the client terminal 10 in step S21. Then, the service device 20 monitors the capacity of the buffer memory in real time during execution of the application in step S23.

In step S25, the service device 20 compares the capacity of the current buffer memory with the capacity of the current buffer memory, and calculates the available time for the remaining buffer memory capacity according to the comparison result.

The service device 20 transmits the execution result of the application to the client terminal 10 in consideration of the remaining buffer memory capacity and system environment information in step S27. Here, if the current capacity of the buffer memory is available, the service apparatus 20 transmits the execution result of the application to the client terminal 10. [ On the other hand, when the capacity of the current buffer memory is close to the maximum buffer memory capacity, the service device 20 stops transmission of the execution result of the application. In addition, when the capacity of the current buffer memory approaches the maximum buffer memory capacity, the service device 20 can stop the transmission of the execution result of the application and request the management of the buffer memory to the client terminal 10.

The client terminal 10 receives the execution result for the application from the service device 20 in step S29, and outputs the execution result for the received application.

Accordingly, when the cloud streaming-based application is executed, the present invention can continuously receive data on the execution result and continuously improve the service quality.

5 is a flowchart illustrating an operation of a service apparatus according to an embodiment of the present invention.

Referring to FIG. 5, the service device 20 receives a signal requesting execution of a cloud streaming-based application from the client terminal 10 in step S41.

The service device 20 collects the maximum buffer memory capacity and system environment information of the client terminal 10 in order to execute the application at the request of the client terminal 10 in step S43. At this time, the capacity of the buffer memory is determined according to the characteristics of the client terminal 10, and the system environment information includes the operating system capacity of the client terminal 10, RAM, screen size, resolution, supportable input signals, Camera pixels, and the like.

The service device 20 executes the application on the basis of the cloud streaming in step S45. In step S47, the service device 20 monitors the capacity of the buffer memory in real time while executing the application. Here, the service apparatus 20 compares the capacity of the maximum buffer memory with the capacity of the current buffer memory, and calculates the available time for the remaining buffer memory capacity according to the comparison result.

The service device 20 checks in step S49 whether or not the remaining capacity of the buffer memory is close to the capacity of the maximum buffer memory. For example, the service apparatus 20 can set the capacity of the maximum buffer memory, which can temporarily store data for execution of an application or another function, to 800 Bytes among the capacity (1 M Byte) of the buffer memory. If the capacity of the currently used buffer memory is 700 Bytes, the capacity of the remaining buffer memory that can store the execution result of the application is 100 Bytes. That is, the capacity of the buffer memory currently in use becomes equal to or greater than 80% of the capacity of the maximum buffer memory, the capacity of the usable buffer memory becomes less than 20% of the capacity of the maximum usable buffer memory, It can be judged that it is close to the maximum capacity.

At this time, the service apparatus 20 controls transfer of the execution result of the application in consideration of the capacity of the remaining buffer memory and the system environment information among the maximum buffer memory capacity. For example, when video data is transmitted as a result of execution of an application when the remaining capacity of the buffer memory is less than 20% of the capacity available for the maximum buffer memory, If video data is transmitted in accordance with the resolution (1600 * 900) of information, a data capacity of 100 bytes is required. However, when the service device 20 transmits the video data of the resolution (1200 * 600) to the client terminal 10 in consideration of the remaining memory capacity of the buffer memory and the system environment information, It can be reduced to 50 Bytes.

When the capacity of the remaining buffer memory is less than 20% of the capacity available for the maximum buffer memory, the service device 20 transmits the execution result of the application to an input signal (keyboard, Mouse, touch, and joystick) and transmits them to the client terminal 10, it is necessary to have a data capacity of 200 Bytes. However, when the service device 20 transmits data considering only the remaining memory capacity of the buffer memory and the input signals (keyboard, mouse) that the client terminal 10 can support, the service device 20 transmits the data to be transmitted to the client terminal 10 The capacity can be reduced to 100 Bytes.

If the current capacity of the buffer memory is close to the maximum buffer memory capacity, the service device 20 stops transmitting the execution result of the application in step S53. On the other hand, if the current capacity of the buffer memory is available, the service device 20 transmits the execution result of the application to the client terminal 10 in step S51. In addition, when the capacity of the current buffer memory approaches the maximum buffer memory capacity, the service device 20 can stop the transmission of the execution result of the application and request the management of the buffer memory to the client terminal 10.

6 is a flowchart illustrating an operation of a client terminal according to an embodiment of the present invention.

Referring to FIG. 6, the client terminal 10 according to the present invention requests execution of a cloud streaming-based application to the service device 20 in step S61. In step S63, the client terminal 10 confirms whether a signal requesting the maximum capacity of the buffer memory for storing the execution result of the application and the system environment information is received from the service device 20.
