Wireless Terminal Attribute Recognition for Connection Establishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless systems face challenges in establishing wireless connections among terminals due to limitations in discovering and connecting with all available video transmitting and receiving terminals, especially when their arrangement and environment affect discoverability.
Innovation Solution
The implementation of wireless terminals with defined attributes for video transmission, reception, and instruction, along with recognition and communication control units, enables the identification and establishment of connections between terminals with opposite attributes, allowing for the formation of wireless connections among connectable terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control terminal discovers and manages all wireless terminals directly, then connection control can be centralized, but the control terminal cannot discover terminals that are out of its direct wireless range
Solution Approach 1:
The patent introduces an intermediary terminal that acts as a relay between the control terminal and terminals outside direct range. The intermediary terminal receives discovery information from the control terminal and forwards it to distant terminals, while also relaying connection requests back to the control terminal. This mediator approach enables the control terminal to indirectly discover and manage all terminals in the network without being within direct wireless range of every terminal.
2Adaptability or versatility
If wireless terminals use cable connections with a video signal switching apparatus, then connection management is centralized, but the wiring and configuration become complicated and cannot quickly cope with layout changes
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. Terminals communicate connection information and establishment requests through wireless signals instead of physical cables. This substitution eliminates the need for complex wiring and allows terminals to be moved or repositioned without reconfiguring physical connections, thereby greatly improving adaptability to layout changes while reducing overall system complexity.
3Loss of information
If a terminal transmits information about all discovered terminals to the control terminal, then the control terminal has complete network awareness, but unnecessary information is transmitted when terminals are not connectable
Solution Approach 1:
The patent applies local quality by having terminals selectively transmit information based on their local connectability status. Instead of uniformly transmitting all discovered terminal information, each terminal assesses whether the discovered terminal is actually connectable (within wireless range and compatible) before reporting it to the control terminal. This selective information transmission reduces unnecessary communication overhead and energy consumption while maintaining the control terminal's awareness of all functional connections in the network.

AI summary
A wireless terminal may include: a communication unit that transmits/receives information; a recognition unit that recognizes whether a wireless terminal having transmitted the information is an opposite attribute wireless terminal based on the information received in the communication unit, when a wireless terminal having an attribute opposite to an attribute of its own terminal between the video transmission attribute and the video reception attribute is defined as the opposite attribute wireless terminal and a wireless terminal having the instruction attribute is defined as an instruction attribute wireless terminal; and a communication control unit that controls the communication unit to transmit information on a wireless terminal recognized as the opposite attribute wireless terminal to the instruction attribute wireless terminal when the recognition unit recognizes that the wireless terminal having transmitted the information is the opposite attribute wireless terminal.
