Image Display Apparatus Remote Control Video Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to display videos from portable terminals on larger screens, as they need to directly operate the portable terminal to control the video playback, limiting their ability to freely enjoy the content.
Innovation Solution
An image display method and apparatus that allows users to control and display videos from portable terminals on larger screens without directly operating the portable terminal, using a remote control device to send coordinate information for internet connection operations, enabling synchronized video playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable terminal is directly operated to control video playback, then the user can control the video functions, but the user convenience is reduced and the operation becomes complicated
Solution Approach 1:
The image display apparatus serves as an intermediary device between the remote control and the portable terminal. It receives coordinate information from the remote control, transmits control signals to the portable terminal, and displays the video output, thereby mediating the control process and eliminating the need for direct terminal operation
Solution Approach 2:
The system creates a copy of the portable terminal's video output on the image display apparatus screen. Users can view and control the video content through this visual copy on the larger screen, which represents the terminal's display state without needing to directly interact with the terminal itself
2Adaptability or versatility
If the portable terminal is connected to display video on larger screen, then the viewing experience is improved, but the user cannot freely enjoy the content due to continuous operation requirements
Solution Approach 1:
The portable terminal operates autonomously after initial connection, managing its own video playback and control operations. The image display apparatus independently processes remote control signals and displays video content, allowing the system to serve itself without requiring continuous user intervention or direct terminal operation
3Productivity
If the user directly operates the portable terminal during video reproduction, then the video can be controlled, but the user cannot freely and fully enjoy the videos
Solution Approach 1:
The image display apparatus acts as a mediator that handles all control operations through the remote control interface. Users can control video playback (play, pause, stop, navigation) by pointing the remote control at the displayed video on the image display apparatus, which then transmits appropriate signals to the portable terminal, eliminating operation interruptions
Solution Approach 2:
The system replaces direct mechanical interaction with the portable terminal (buttons, touchscreen) with an optical-mechanical remote control system. The remote control uses infrared or radio frequency signals to communicate with the image display apparatus, which then translates these signals into terminal control commands, substituting direct operation with a more convenient remote interface
Data Source
AI summary
An image display apparatus including a display unit a data on a screen; a communication unit receiving a signal transmitted from a remote control device; and a control unit configured to detect whether an external device is connected to the apparatus; display a menu allowing an user to select whether or not to transmit an image being displayed on the external device to the screen; and display the image on the screen.
