The input information corresponding to the image area attribute information included in the first code may be rendered to generate a captured image.

In addition, the cloud streaming server 110 uses the still image compression technique to still image encode the captured image. At this time, a still image encoding method corresponding to one of portable network graphics (PNG), portable network graphics (PNG), and joint image experts group (JPEG) may be used to still image encode the captured image.

Also, the cloud streaming server 110 transforms the still image-encoded captured image and the first code so as to generate an application result screen on the terminal devices 120-1, ..., and 120-N to include the animation information And transmits the generated second code to the user terminal to perform a still image based cloud streaming service.

The terminal devices 120-1 to 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 terminal devices 120-1 to 120-N is connected to a communication network and is capable of executing applications on the basis of a cloud computing system. The terminal devices 120-1 to 120-N are not limited to mobile communication terminals, Terminal, a fixed terminal, and an IP (Internet Protocol) terminal. Each of the terminal devices 120-1 to 120-N may be a mobile phone, a portable multimedia player (PMP), a mobile internet device (MID), a smart phone, a desktop, a tablet A mobile terminal having various mobile communication specifications such as a PC, a notebook, a netbook, a personal digital assistant (PDA), a smart TV, and an information communication device.

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

1, the cloud streaming server shown in FIG. 1 includes a code receiving unit 210, a captured image information generating unit 220, an animation information generating unit 230, a code converting unit 240, a capturing unit 250, An encoding unit 260, a transmitting unit 270, and a storage unit 280.

The code receiving unit 210 receives the first code corresponding to the application result screen from the web application server. The first code may include animation information about an animation effect applied when an application is executed and image region attribute information about images to which an animation effect is applied. It can also be written in a way that web application developers use. For example, the first code can be created using a library such as jQuery that is widely used for animation purposes.

The captured image information generating unit 220 generates captured image information using the image area attribute information included in the first code. For example, the image area attribute information may be coordinate information for the image to be captured.

The animation information generating unit 230 generates animation information using the animation code included in the first code. The animation code included in the second code is a code for executing an animation, and unnecessary capturing may be performed when the code is executed. Therefore, the contents of the animation code can be confirmed and the animation information can be generated using the information that can be extracted.

The code conversion unit 240 converts the first code into a second code including the captured image information and the animation information. Therefore, by confirming the second code, detailed information about the capture area and the animation can be grasped.

At this time, the second code may include animation information corresponding to at least one of an animation type, an animation application time, an animation repetition number, a start coordinate, an end coordinate, a start size and an end size. For example, in the second code, the animation type is 'effect type', the animation application time is 'duration', the animation repetition number is isRepeat, the start coordinates are start X and start Y, end Y ', start size' start W, start H 'and end size can be indicated as' end W, end H'.

At this time, a still image encoding method corresponding to one of portable network graphics (PNG), portable network graphics (PNG), and joint image experts group (JPEG) may be used to still image encode the captured image.

In PNG still image compression, image quality is good when encoding, but when the bandwidth of the transmission network is low due to a large data size, the transmission speed may be lowered.

PALETED PNG still image compression techniques can reduce the data size of the image during encoding, which can guarantee the transmission speed, but it can cause deterioration in image quality because it expresses color with 8 bits.

The JPEG Still Image Compression technique can greatly reduce the amount of data transferred during encoding because of its high compression efficiency. However, when encoding and decoding are performed, the system load may be increased.

The sending unit 270 converts the still image-encoded captured image and the first code so as to generate an application result screen at the user terminal, and transmits a second code generated to include the animation information to the user terminal, Perform cloud streaming service. For example, the application result screen may be completely generated and streamed by the cloud streaming server 110, but the application result screen may be generated by the user terminal in the same manner as described above, so that the load generated in the cloud streaming server 110 Can be significantly reduced. As the load of the cloud streaming server 110 is reduced, the number of services that can be simultaneously processed by the cloud streaming server 110 increases, so that more users can simultaneously receive services.

The storage unit 280 stores various information generated in the cloud streaming service process according to the embodiment of the present invention as described above.

According to an embodiment, the storage unit 280 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 280 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 can store information in the memory on which the memory is mounted. 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 include, for example, a hard disk device, an optical disk device, or any other mass storage device.

In the terminal area 305, an application result screen can be generated using the captured image and the second code received from the cloud streaming server area 300. That is, the captured image may be animated 360 based on the animation information and the captured image information included in the second code. Since the animation information includes information such as animation type, animation application time, animation repetition count, start coordinate, end coordinate, start size, and end size, animation can be accurately and easily applied to the captured image, Can be generated.
