Cross-Display Annotation Sync With Reduced Bandwidth Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges with resolution differences between mobile terminals and large-size display terminals, leading to inefficient operations and high network bandwidth requirements for real-time synchronization, which can be problematic in interactive demonstrations.
Innovation Solution
A method for a first display device to display annotation information and send it to a second display device, allowing the second device to display the information in corresponding areas, while reducing the need for full-area content transmission and optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full-area display content is transmitted in real-time for synchronization between mobile terminal and large-size display terminal, then display synchronization is improved, but network bandwidth requirements increase significantly
Solution Approach 1:
The patent extracts only the annotation information from the full-area display content and transmits it to the mobile terminal. Instead of synchronizing the entire display content, the system extracts and transmits only the necessary annotation data, significantly reducing bandwidth requirements while maintaining synchronization of the important annotation elements.
Solution Approach 2:
The patent segments the display content into full-area content and annotation information. The full-area content remains on the large-size display terminal, while only the annotation information is extracted and transmitted to the mobile terminal for display on the smaller screen. This segmentation allows selective transmission of only the necessary information.
2Measurement precision
If annotation is performed on large-size display terminal, then annotation precision is improved, but device portability and operation convenience deteriorate
Solution Approach 1:
The patent introduces an intermediary system where the large-size display terminal and mobile terminal cooperate through wireless communication. The mobile terminal acts as a portable intermediary that receives annotation information from the large-size display terminal and displays it locally, allowing the user to perform annotations on a portable device while maintaining precision through the connection with the large-size display system.
Solution Approach 2:
The patent transitions from a single large-size display dimension to a distributed dimension system. The large-size display terminal provides the full-area content and annotation precision, while the mobile terminal provides portability. The wireless communication link connects these two dimensions, allowing the system to leverage the advantages of both without being constrained by the limitations of either single device.
3Ease of operation
If annotation information is displayed on mobile terminal, then operation convenience is improved, but display area and visible content reduce
Solution Approach 1:
The patent applies partial action by displaying only the annotation information on the mobile terminal rather than the full-area display content. The mobile terminal displays only the necessary annotation elements, which are sufficient for the user to perform operations conveniently, while the complete content remains available on the large-size display terminal.

AI summary
The present disclosure provides an information display method, a display device, an electronic device, and a computer-readable medium, the information display method including: in a case where a first display device displays content to be annotated, displaying annotation information corresponding to the content to be annotated, in response to an annotation operation for the content to be annotated; and sending the annotation information to a second display device, so that the second display device displays the annotation information in an area corresponding to the content to be annotated.
