Display Device Screen Mirroring History Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital TV services, such as IPTV and smart TV, lack the ability to provide information on previous screen mirroring sessions and shared content between devices, limiting user interaction and service enhancement.
Innovation Solution
A display device configuration that includes a broadcast reception unit, external device interface, storage, user input interface, control unit, short-range communication unit, and remote control device, enabling screen mirroring history tracking and content transmission requests between devices through a network interface and external device interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If screen mirroring function is implemented in digital TV services, then user interactivity and service capability are improved, but ability to provide history information and shared content information is lost
Solution Approach 1:
The system performs preliminary actions by automatically storing mirroring history information and shared content information in the storage unit during screen mirroring operations. This preliminary data collection enables later retrieval and display of history information without interfering with the real-time screen mirroring function.
Solution Approach 2:
The control unit acts as an intermediary between the screen mirroring function and the history information provision. It manages both the active screen mirroring operation and the parallel function of storing and retrieving history information, allowing both functions to coexist without conflict.
2Ease of operation
If screen mirroring history tracking is added, then user interaction is enhanced, but device complexity increases
Solution Approach 1:
The storage unit and control unit are designed to serve multiple functions: they store and manage both active screen mirroring data and history information. This multi-functionality reduces the need for separate dedicated components for history tracking, thereby limiting the increase in device complexity.
Solution Approach 2:
The system provides self-service by automatically tracking and storing mirroring history information without requiring additional user intervention or complex external systems. The control unit autonomously manages the collection, storage, and retrieval of history data.

AI summary
An operating method of a display device includes displaying an external input list including a plurality of external input items; receiving a first request for selecting an external input item for screen mirroring from the plurality of external input items; and displaying a mirroring item including at least one of information on an external device that performs a screen mirroring function previously with the display device and information on a content provided through the external device according to the received first request.
