Cloud Streaming Terminal Local Image Prestorage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cloud-streaming-based image data provision systems face high network load and increased costs due to continuous video data transmission, even when live or VOD videos are not being watched, leading to inefficient resource utilization.
Innovation Solution
The method involves prestoring image data in a terminal, capturing an execution screen of a specific application, extracting video content based on the screen information, encoding individual items, and providing the encoded content, allowing for local playback and reduced network usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is continuously transmitted in cloud streaming service, then service availability is improved, but network load and transmission costs increase
Solution Approach 1:
The patent applies preliminary action by prestoring image data in the terminal before it is actually needed. The terminal receives and stores image data from the server in advance, so that when a user wants to view content, the data is already available locally without requiring continuous network transmission. This resolves the contradiction by maintaining service availability through local storage while reducing network load during idle periods.
2Reliability
If video data is continuously transmitted to ensure service availability, then user access reliability is improved, but transmission costs increase
Solution Approach 1:
The terminal prestores image data in advance, ensuring that content is available for immediate access without continuous transmission. This preliminary storage action guarantees user access reliability while avoiding the ongoing transmission costs that would otherwise be incurred to maintain constant data availability.
3Reliability
If cloud streaming transmits all video data, then complete content delivery is achieved, but network resource utilization efficiency decreases
Solution Approach 1:
The patent extracts only the necessary video data from the complete content and stores it in the terminal. Instead of transmitting all video data continuously, the system extracts and stores only the specific image data that users are likely to access, thereby maintaining content delivery completeness for accessed content while significantly improving network resource utilization efficiency by avoiding unnecessary transmissions.
4Adaptability or versatility
If live video or VOD video is not watched but continuously transmitted, then service readiness is maintained, but unnecessary network load increases
Solution Approach 1:
The system implements periodic action by transmitting and storing video data in intervals rather than continuously. The terminal receives image data at specific periods and stores it locally, maintaining service readiness for future playback without the continuous network load. This allows the system to be adaptable and versatile when content is actually viewed while avoiding unnecessary network energy consumption during idle periods.

AI summary
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 to minimize network load required to transmit video data, 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. Purchasing paid videos may be encouraged by showing movie previews, drama trailers, advertisements, etc. in a standby state to increase sales.
