Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image transmitting/receiving systems face challenges in switching communication connections without disrupting the transmission/reception of image signals, particularly when changing connected devices during streaming distribution.
Innovation Solution
The system employs a reference synchronization signal to synchronize image signal transmission with vertical blanking intervals, allowing for disconnection processes during these intervals to switch connections without affecting image signal transmission/reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connection switching is performed during streaming distribution, then device adaptability is improved, but image signal transmission reliability deteriorates due to potential interruptions
Solution Approach 1:
The patent segments the communication protocol into distinct layers: a higher-layer protocol for connection management and switching, and a lower-layer protocol for continuous image signal transmission. This segmentation allows connection switching operations to occur at the higher layer without disrupting the continuous transmission at the lower layer, thus maintaining both adaptability and reliability.
Solution Approach 2:
The patent implements preliminary actions by establishing connection switching mechanisms and protocols before actual switching is needed. The system pre-configures multiple connection paths and prepares switching logic in advance, allowing seamless transitions without interrupting the ongoing image signal transmission, thereby maintaining transmission reliability while enabling device adaptability.
2Ease of operation
If connection switching is performed during image transmission, then ease of operation is improved, but transmission stability deteriorates due to potential disruptions
Solution Approach 1:
The patent divides the communication system into independent functional layers: connection management functions operate separately from image transmission functions. This segmentation enables easy connection switching through higher-layer protocols while the lower-layer image transmission maintains stable, continuous operation without disruptions.
Solution Approach 2:
The patent introduces an intermediary connection management layer that mediates between user switching operations and the underlying image transmission process. This intermediary handles switching requests and coordinates transitions without directly interfering with the stable image signal flow, thus maintaining transmission stability while improving ease of operation.
3Adaptability or versatility
If wireless communication connection is disconnected and reconnected, then adaptability is improved, but loss of time occurs during reconnection process
Solution Approach 1:
The patent performs preliminary actions by maintaining connection state information and configuration data in advance. When disconnection and reconnection occur, the system can rapidly restore the connection using pre-configured parameters and cached state information, significantly reducing reconnection time while maintaining adaptability for switching between different devices.
Solution Approach 2:
The patent uses copying mechanisms by maintaining backup connection state information and configuration data. During reconnection, instead of establishing a completely new connection, the system copies and restores the previous connection state, enabling rapid reconnection with minimal time loss while preserving the ability to switch to different devices when needed.

AI summary
A received image displaying apparatus comprises: a wireless communication unit that wirelessly receives the frame images transmitted by the image transmitting apparatus with which the received image displaying apparatus has established a connection of wireless communication; and a displaying unit that displays the frame images, which were wirelessly received by the wireless communication unit, in an order in which the frame images were captured. At least one of the image transmitting apparatus and the received image displaying apparatus comprises: a reference sync signal generating unit that generates the reference sync signals; and a control unit that, if the wireless communication unit has received no reference sync signals for a certain time interval, controls the reference sync signal generating unit to generate reference sync signals and that further controls the wireless communication unit to wirelessly transmit the reference sync signals to the other apparatus included in the image transmitting/receiving system.
