Terminal Mirroring With Dual-Protocol Activation and Device Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirroring technologies often require manual activation of the mirroring function on devices with small displays, leading to increased battery consumption and user inconvenience when devices not intended for sharing are included in connectable lists.
Innovation Solution
A method for automatically identifying and activating the mirroring function on deactivated terminals using different communication protocols, prioritizing terminals with matching account information and obtaining user consent for non-related devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mirroring function is activated in advance on devices with small displays, then mirroring connectivity is improved, but battery consumption increases
Solution Approach 1:
The source terminal performs preliminary identification of candidate sink terminals before mirroring connection is established. By using capability information exchanged through the first communication protocol, the source terminal can pre-determine which devices support mirroring functionality, avoiding the need for continuous scanning or keeping the mirroring function continuously active on sink terminals.
Solution Approach 2:
The patent introduces capability information as an intermediary mechanism that mediates between the source terminal and potential sink terminals. This capability information, exchanged via the first communication protocol, serves as a preliminary filter that enables the source terminal to identify suitable mirroring targets without requiring the sink terminals to continuously maintain active mirroring functions.
2Use of energy by moving object
If the mirroring function is deactivated on devices with small displays, then battery consumption is reduced, but user convenience deteriorates when manual activation is required
Solution Approach 1:
The source terminal performs self-service by automatically identifying candidate sink terminals using capability information and automatically establishing mirroring connections. This eliminates the need for users to manually navigate to settings, enable mirroring functions, or configure connection parameters on sink terminals, thereby maintaining ease of operation while keeping the mirroring function deactivated on portable devices.
Solution Approach 2:
The system performs preliminary identification and capability exchange before the actual mirroring connection is needed. By having sink terminals pre-advertise their capability information through the first communication protocol, the source terminal can automatically initiate connections without requiring users to perform manual activation steps when mirroring is actually needed.
3Adaptability or versatility
If all devices are included in the connectable terminal list, then device discoverability is improved, but user confusion increases when unrelated devices appear
Solution Approach 1:
The patent applies local quality by differentiating between types of devices in the terminal list based on their capability information. Sink terminals that have demonstrated mirroring capability through the first communication protocol are presented with distinct visual characteristics (such as icons, labels, or positioning) compared to other devices, allowing users to quickly identify appropriate mirroring targets without confusion from unrelated devices.
Solution Approach 2:
Capability information is exchanged in advance through the first communication protocol, performing a preliminary filtering action that distinguishes mirroring-capable devices from other devices before they appear in the connectable terminal list. This preliminary identification allows the system to present only relevant devices or clearly mark relevant devices, improving user clarity while maintaining comprehensive device discoverability.
Data Source
AI summary
A mirroring method performed by a source terminal, includes: identifying, according to a first communication protocol, a first terminal having a mirroring function that is deactivated; outputting a terminal list including identification information of the first terminal; based on the first terminal being selected from the terminal list, transmitting a request for activation of the mirroring function to the first terminal according to the first communication protocol; and transmitting, according to a second communication protocol, content to the first terminal with the mirroring function that is activated in response to the request for the activation.
