Wireless Screen Projection Receiver Preemption Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless screen projection devices lack effective control over screen preemption authority, leading to confusion and disruption in presentation order during conferences, as users can preempt the screen without moderator confirmation.
Innovation Solution
A wireless screen projection method and device that allows a moderator to control screen preemption permissions through a receiver with an input module, enabling confirmation of screen preemption requests from transmitters, ensuring orderly presentations by allowing only validated requests to proceed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users can preempt the screen at any time by operating the transmitter keys, then each user can conveniently realize screen projection functions, but the presentation order becomes confused and the meeting order is disrupted
Solution Approach 1:
The patent introduces a receiver as an intermediary device that mediates between multiple transmitters and the display screen. The receiver receives preemption requests from transmitters and controls screen switching based on predefined rules or moderator input, preventing direct uncontrolled preemption while maintaining user convenience.
Solution Approach 2:
The system implements feedback mechanisms where the receiver monitors preemption requests and provides status information back to transmitters. This feedback loop allows the system to regulate preemption behavior dynamically, ensuring orderly presentation while maintaining operational flexibility.
2Adaptability or versatility
If multiple transmitters are allowed to connect to a single receiver for intelligent interaction, then user functionality is enhanced, but control over screen preemption authority is lost
Solution Approach 1:
The patent applies different control qualities to different transmitters based on their roles. The receiver can distinguish between moderator transmitters and participant transmitters, applying different preemption rules and authority levels to each type, thereby maintaining both versatility and control.
Solution Approach 2:
The system dynamically adjusts preemption authority based on the current state and role assignments. Control rights are not fixed but can be dynamically allocated to different transmitters based on meeting progression, moderator decisions, and system state, balancing versatility with controlled operation.

AI summary
A wireless screen projection method for a wireless network including a receiver that includes a first input module and at least one transmitter, includes: switching, using the receiver, to a preemption enabled mode in response to a first trigger signal received by the receiver that is generated by the first input module in response to a user's first operation on the first input module; and in the preemption enabled mode, sending, using the receiver, a projection instruction to a target transmitter in response to a screen preemption request sent by the target transmitter. The projection instruction is to trigger the target transmitter to send audio and video data of a terminal device connected to the target transmitter to the receiver through the wireless network, and the receiver is to transmit the audio and video data to a display device connected to the receiver.
