Screen Projection Control via Pre-Startup Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen projection methods are inefficient as they require large-screen display terminals to be started up first, followed by connection with small-screen mobile terminals, resulting in a delay of 10 to 30 seconds before content can be displayed, which hampers rapid response to user needs.
Innovation Solution
A method where a first electronic device sends a packet to paired second electronic devices to start up in a screen-off state, allowing them to directly transition to a screen-on state upon receiving screen projection data, thereby bypassing the need for a full startup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the large-screen display terminal is started up first before establishing connection with the small-screen mobile terminal, then the connection can be established properly, but the time consumption increases to 10-30 seconds
Solution Approach 1:
The large-screen display terminal is started up in advance and remains in a ready state before the user initiates screen projection. The system pre-establishes the display terminal's operational state so that when projection is needed, it can immediately accept connections without requiring full startup during the projection process, thereby reducing the 10-30 second delay while ensuring proper connection establishment
2Productivity
If the large-screen display terminal remains in a ready state without full startup, then the screen projection time is reduced, but the system may not be fully operational
Solution Approach 1:
The large-screen display terminal dynamically adjusts its operational state between a low-power ready state and a full operational state. When screen projection is detected, the system quickly transitions from the ready state to full operation, enabling rapid screen projection (reducing time loss) while ensuring the system is fully operational when needed (maintaining reliability). This dynamic state management allows the system to optimize both productivity and reliability

AI summary
The present disclosure relates to a screen projection control method, device and medium. The method is applicable to a first electronic device, wherein the first electronic device has been paired with one or more second electronic devices, the method includes: in response to detecting a setting operation, sending a first packet to the second electronic devices that have been paired, wherein the first packet is configured to control the second electronic devices to start up in a screen-off state; and when the second electronic devices are in a start-up state, in response to receiving a screen projection instruction, sending screen projection data to the second electronic devices to enable the second electronic devices to enter a screen-on state after receiving the screen projection data and display the received screen projection data.
