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

Referring to FIG. 1 , the cloud streaming service system according to an embodiment of the present invention includes a cloud streaming server 110 , terminal devices 120-1, ..., 120-N, a web application server 130 and a network 140 . ) is included.

Cloud streaming server 110 receives the first code corresponding to the application result screen from the web application server (130).

In addition, the cloud streaming server 110 converts the first code into a second code including captured image information and animation information. In this case, 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. In this case, the second code may not include the animation code.

In addition, the cloud streaming server 110 may generate a captured image by capturing an area corresponding to the captured image information included in the second code of the application result screen.

In addition, the cloud streaming server 110 may generate the captured image information by using the image region property information included in the first code.

In addition, the cloud streaming server 110 may generate animation information by using the animation code included in the first code.

In addition, the cloud streaming server 110 generates a captured image based on the captured image information included in the second code. In this case, a captured image may be generated by capturing an area corresponding to the captured image information included in the second code of the application result screen. A captured image may be generated by rendering the input information corresponding to the image region attribute information included in the first code.

Also, the cloud streaming server 110 encodes the captured image as a still image using a still image compression technique. In this case, the captured image may be encoded as a still image by using a still image compression technique corresponding to any one of portable network graphics (PNG), paletted portable network graphics (PNG), and joint photography experts group (JPEG).

In addition, the cloud streaming server 110 converts the still image-encoded captured image and the first code so as to generate an application result screen in the terminal devices 120-1, ..., 120-N to include animation information. A still image-based cloud streaming service is performed by transmitting the generated second code to the user terminal.

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

Each of the terminal devices 120-1, ..., 120-N is connected to a communication network and is a device capable of executing an application based on a cloud computing system, and is not limited to a mobile communication terminal, and all information and communication devices, multimedia terminals, and wired It may be various terminals, such as a terminal, a fixed terminal, and an IP (Internet Protocol) terminal. In addition, the terminal devices 120-1, ..., 120-N are, respectively, a mobile phone, a Portable Multimedia Played (PMP), a Mobile Internet Device (MID), a smart phone, a desktop, and a tablet computer. PC), a notebook (Notebook), a netbook (Net Book), a personal digital assistant (PDA), may be a mobile terminal having various mobile communication specifications such as a smart TV and information communication device.

The web application server 130 is a server that receives and processes requests from the terminal devices 120-1, ..., 120-N. Rather than processing all the requests received from the terminal devices 120-1, ..., 120-N in the web application server 130, the functions of the web application server 130 may be structurally separated and processed through web containers. Therefore, as the number of service requests from the terminal devices 120-1, ..., 120-N increases, the method of providing a service using the web application server 130 may be more effective. For example, BEA's WEB LOGIC, IBM's Web Spere, T-max's JEUS, Tomcat, RedHot's Jboss, etc. may correspond to the web application server 130 .

The web application server 130 may transmit the application code corresponding to the application result screen to the cloud streaming server 110 based on the service request received from the terminal devices 120-1, ..., 120-N.

It may be different from the network or may be the same.

FIG. 2 is a block diagram illustrating an example of the cloud streaming server shown in FIG. 1 .

Referring to FIG. 2 , 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 , and a capturing unit 250 . , an encoding unit 260 , a sending 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. Such a first code may include animation information on an animation effect applied when an application is executed, image area property information on images to which an animation effect is applied, and the like. In addition, it may be written in a way that web application developers have previously used. For example, the first code may be written using a library such as jQuery, which is widely used for animation purposes.

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

The animation information generator 230 generates animation information by using the animation code included in the first code. The animation code included in the second code is a code for executing animation, and when executing the corresponding code, unnecessary capture may be required. Accordingly, it is possible to check the contents of the animation code and generate animation information using information that can be extracted.

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

In this case, 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 number of animation repetitions is 'isRepeat', the start coordinates are 'start X, start Y', the end coordinates are 'end X, end Y', the start size may be expressed as 'start W, start H', and the end size may be expressed as 'end W, end H'.

In this case, the second code may not include the animation code.

The capture unit 250 generates a captured image based on captured image information included in the second code. In this case, a captured image may be obtained by rendering the application result screen and capturing only an area corresponding to the captured image information. In this case, the captured image information may include pixel coordinate values at which animation is to be displayed on the application result screen.

The encoding unit 260 encodes the captured image as a still image by using a still image compression technique.

In this case, the captured image may be encoded as a still image by using a still image compression technique corresponding to any one of portable network graphics (PNG), paletted portable network graphics (PNG), and joint photography experts group (JPEG).

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

The paletted PNG still image compression technique reduces the data size of the image during encoding, so the transmission speed can be guaranteed, but since the color is expressed in 8 bits, it can cause deterioration in image quality.

Since the JPEG still image compression technique has good compression efficiency, the amount of transmitted data can be greatly reduced during encoding. However, since the compression efficiency is high, it can generate a lot of system load when encoding and decoding.

The sending unit 270 converts the still image-encoded captured image and the first code so that the user terminal can generate the application result screen, and transmits the second code generated to include animation information to the user terminal, Cloud streaming service. For example, the cloud streaming server 110 may completely generate and stream the application result screen, but the load generated in the cloud streaming server 110 by transmitting the application result screen to the user terminal in the same way as above. can be significantly reduced. As such, when 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 receive the service at the same time.

The storage unit 280 stores various information generated in the process of the cloud streaming service 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 a cloud streaming service. In this case, the storage unit 280 may operate as a separate mass storage and may include a control function for performing an operation.

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 equipped with a memory can store information in the device. For one implementation, the memory is a computer-readable medium. In one implementation, the memory may be a volatile memory unit, and in another implementation, the memory may be a non-volatile memory unit. In one embodiment, 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 some other mass storage device.

In addition, in the cloud streaming server area 300 , the captured image and the second code on which the encoding 330 is performed may be streamed 350 to the terminal area 305 together. In this case, the captured image and the second code may be included in one message and transmitted, or each message may be generated and transmitted.

The terminal area 305 may generate an application result screen using the captured image and the second code received from the cloud streaming server area 300 . That is, based on the animation information and the captured image information included in the second code, the animation may be applied (360) to the captured image. At this time, since the animation information includes information such as animation type, animation application time, animation repetition number, start coordinates, end coordinates, start size and end size, it is possible to accurately and easily apply the animation to the captured image to display the application result screen. can create
