Method of providing image data based on cloud streaming, and apparatus therefor
The present invention relates to a method of providing image data based on cloud streaming. In particular, the method uses memory space of a terminal, prestores image data in the terminal, captures an execution screen regarding execution of a specific application, extracts video content from the prestored image data based on the captured execution screen and information regarding the execution screen, simultaneously encodes individual items of the extracted video content, and provides the encoded video content to a screen. Thus, according to the present invention, usage of the cloud streaming server and the network may be reduced by an amount commensurate with the resources utilization of the terminal. Network load may also be reduced when a live video or a VOD video is not being watched, and the rich GUI experience may be guaranteed in a standby state.
1. A service device for executing an application upon request from a terminal and providing an execution screen to the terminal based on cloud streaming, the service device comprising:
one or more processors;
memory; and
one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
transmitting a plurality of video content items via a network every certain period or at certain times for storing in the terminal before execution of an application,
receiving a request to execute the application from the terminal via the network,
responsive to receiving the request, executing the application to at least generate the execution screen of the application including a graphic user interface (GUI) screen and an associated video content item corresponding to one of the plurality of the video content items previously stored in the terminal,
capturing, from the execution screen of the application, only the GUI screen, and
providing, via the network, to the terminal the captured GUI screen a content ID of the associated video content item for indicating the corresponding one of the plurality of video content items previously stored in the terminal, and location information indicating a location of the video content item to be displayed with the captured GUI screen on the terminal to cause
the terminal to combine the captured GUI screen received from the service device and the corresponding one of the plurality of video content items previously stored in the terminal into a combined content and display the combined content on the terminal.
2. A terminal for receiving an execution screen of an application from a service device based on cloud streaming through a network, the terminal comprising:
one or more processors; and
memory storing one or more programs configured to be executed by the one or more processors, the one or more programs including instructions for:
receiving a plurality of video content items via a network every certain period or at certain times before requesting the service device to execute an application,
storing the plurality of video content items in the memory of the terminal,
sending a request to the service device, via the network, to execute the application and generate an execution screen of the application including a graphic user interface (GUI) screen and an associated video content item corresponding to one of the plurality of the video content items previously stored at the terminal,
receiving from the service device, via the network, a GUI screen captured by the service device, a content ID of the associated video content item for indicating the corresponding one of the plurality of video content items previously stored in the terminal, and location information indicating a location of the video content item to be displayed with the captured GUI screen on the terminal,
extracting, from the memory, based on the content ID, the corresponding one of the plurality of video content items
combining the extracted one of the plurality of video content items with the GUI screen according to the location information, and
displaying the combined content.
3. A method of providing image data based on cloud streaming, the method comprising:
transmitting, by a service device, a plurality of video content items via a network every certain period or at certain times for storing in the terminal before execution of the application;
receiving, by the service device via the network, a request to execute the application from the terminal;
responsive to receiving the request by the service device, executing the application to at least generate an execution screen of the application including a graphic user interface (GUI) screen and an associated video content item corresponding to one of the plurality of the video content items previously stored in the terminal;
capturing, by the service device, from the execution screen of the application, only the GUI screen; and
providing, by the service device via the network, to the terminal, a content ID of the associated video content item for indicating the corresponding one of the plurality of video content items previously stored in the terminal, and location information indicating a location of the video content item to be displayed with the captured GUI screen on the terminal to cause the terminal to combine the captured GUI screen and the corresponding one of the plurality of video content items into a combined content and display the combined content on the terminal.
