Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of maintaining and operating cloud servers for digital TV services, such as IPTV and smart TV, and the need for a cost-effective solution to provide interactive services without relying on cloud infrastructure.
Innovation Solution
A screen sharing service using a high-performance source device that connects with a low-specification sink device, enabling automatic connection, remote control of applications, and optimized video/audio mode settings, thereby eliminating the need for a separate cloud server and facilitating service upgrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cloud server is used to provide digital TV services, then interactivity and various additional services can be provided, but a large cost is paid for the construction, management, and maintenance of the infrastructure
Solution Approach 1:
The patent extracts the cloud server infrastructure from the system by implementing a peer-to-peer architecture where the source device (smartphone) directly provides services to the sink device (TV) through wireless communication. This eliminates the need for a separate cloud server while maintaining interactivity and additional services through direct device-to-device communication.
Solution Approach 2:
The source device performs self-service by directly providing TV services, search functions, and additional applications to the sink device without requiring cloud server infrastructure. The high-performance source device leverages its own processing capabilities and storage to deliver services that would traditionally require expensive cloud infrastructure.
2Adaptability or versatility
If a high-performance source device is used to provide services, then service functionality is improved, but the cost of using a cloud server is eliminated
Solution Approach 1:
The patent creates a virtual copy of cloud server functionality by running service applications directly on the source device's processor and memory. The source device replicates cloud-based services locally, providing search functions, TV broadcasting, and additional applications without actually connecting to a cloud server infrastructure.
3Ease of operation
If automatic connection and remote control features are implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The wireless communication interface is designed with multi-functionality to handle various operations including service discovery, connection establishment, screen sharing, and remote control signals. This single interface manages multiple functions that would traditionally require separate systems, improving ease of operation while controlling overall complexity.
