Mobile Device Mirroring Protocol Switching for Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During image mirroring between mobile devices and display apparatuses, users cannot control playback operations on the display apparatus screen, and network bandwidth limitations can result in poor image quality, especially when trying to view images in full screen mode.
Innovation Solution
The mobile device detects user inputs on the display apparatus and switches the transfer protocol from mirroring to casting, allowing the display apparatus to adaptively display high-resolution images and enabling user control over playback operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mirroring protocol is used to display content on display apparatus, then real-time image transmission is achieved, but user cannot control playback operations on the display apparatus screen
Solution Approach 1:
The mobile device acts as an intermediary that receives touch inputs from the display apparatus, identifies the corresponding OSD menu items, and executes the operations. This mediator approach enables control functionality on the display apparatus screen while maintaining the mirroring protocol's real-time image transmission capability.
2Reliability
If network bandwidth is limited during mirroring, then connection stability is maintained, but image quality deteriorates when displaying high-resolution images
Solution Approach 1:
The system dynamically switches between mirroring and casting protocols based on operational needs. During normal operation, mirroring provides stable real-time display. When full-screen or high-quality display is required, the system transitions to casting protocol which handles high-resolution images more effectively, adapting to different bandwidth conditions.
3Speed
If mirroring protocol transmits image data in real-time, then low latency is achieved, but network bandwidth consumption increases for high-resolution images
Solution Approach 1:
The system dynamically selects between mirroring and casting protocols based on display requirements. For standard viewing, mirroring provides low-latency real-time transmission. When high-resolution or full-screen display is needed, the system switches to casting which optimizes bandwidth usage for high-quality image transmission.
4Ease of operation
If display apparatus screen is used as touch screen during mirroring, then display functionality is improved, but touch input operations cannot be executed
Solution Approach 1:
The display apparatus screen serves multiple functions: it displays the mirrored content and also accepts touch inputs. The mobile device's processor identifies touch positions on the display apparatus screen and maps them to corresponding OSD menu items, enabling the screen to function both as a display and a control interface.

AI summary
An electronic apparatus includes a processor configured to: display content as a first image including a playback area, transmit data of the first image to a first external apparatus, identify whether a first user input is to request a change in a playback area of a second image, based on the first user input generated in the first external apparatus, in which the content is being displayed as the second image including a playback area identical to the playback area of the first image, and, based on the identifying the first user input is to request the change in the playback area of the second image, transmit a request, to the first external apparatus, to display the content as a third image including a playback area different from the playback area of the first image and maintain the playback area of the first image on the display.
