Electronic Device Interoperability with Companion Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient method enabling electronic devices that receive audio/video (A/V) content to interoperate with peripheral devices, particularly in enabling companion screens to function seamlessly with primary devices, especially in broadcasting and media communication systems.
Innovation Solution
An electronic device and companion device system that utilizes communication circuitry and controllers to recognize triggers for application execution, transmit notification messages, and share keys to facilitate interoperability, allowing companion devices to be used as secondary screens and access resources for A/V content services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a TV device provides only unidirectional broadcast signal reception and display, then the device structure remains simple, but the device cannot interoperate with peripheral devices or provide additional services
Solution Approach 1:
The TV device is enhanced with additional communication circuitry and controller functions to perform multiple roles: receiving broadcast signals, discovering companion devices, establishing connections, and providing A/V output services. This multi-functional approach enables the TV to serve as both a traditional broadcast receiver and a smart hub for peripheral device interoperability.
Solution Approach 2:
The controller acts as an intermediary between the broadcast signal receiver and the companion device. It manages the discovery process, establishes connections, and coordinates A/V content transmission, thereby enabling interoperability without requiring complex direct integration between all components.
2Adaptability or versatility
If a TV device adds functions to output various A/V content and provide additional services, then the device functionality is improved, but the device complexity increases
Solution Approach 1:
The system functionality is segmented into distinct modules: the TV device handles broadcast reception and A/V content processing, while the companion device handles display and user interaction. The controller divides the interoperability tasks into discovery, connection establishment, and content transmission phases, reducing the complexity burden on any single component.
3Reliability
If the TV device implements comprehensive device discovery and connection establishment protocols, then the interoperability reliability is improved, but the operation time and processing complexity increase
Solution Approach 1:
The controller performs device discovery and connection establishment in advance before A/V content transmission is needed. By pre-establishing connections and verifying device compatibility, the system ensures reliable interoperability while minimizing the time required during actual content delivery, as the groundwork is already completed.

AI summary
An electronic device includes a communicator comprising communication circuitry; and a controller configured to recognize a trigger for an execution request of an application for interoperating with a companion screen and to transmit a notification message including a key identifying the application of a companion device and information for calling the application to a notification server that provides a notification service with respect to the application to the companion device through the communication circuitry of the communicator.
