Mobile Terminal Multi-Protocol Content Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals can only support one projection protocol, limiting compatibility with projection services from different equipment and preventing content projection due to protocol incompatibility.
Innovation Solution
A mobile terminal runs a local playing service and multiple protocol projection control services, allowing it to intercept and transmit content using different projection protocols to match the protocols supported by various playing equipment, ensuring compatibility and seamless content projection across different devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile terminal supports only one projection protocol, then the device complexity is reduced, but the adaptability with different projection services deteriorates
Solution Approach 1:
The patent implements multi-functionality by enabling the mobile terminal to run multiple protocol projection control services (DLNA, AirPlay, Miracast) simultaneously within a single projection application. This allows the terminal to adapt to different projection services and protocols, making the device universally compatible with various projection equipment without requiring separate applications for each protocol.
Solution Approach 2:
The patent segments the projection control functionality into distinct protocol-specific control services (DLNA projection control service, AirPlay projection control service, Miracast projection control service). Each service handles a specific protocol independently, allowing the system to manage multiple protocols without creating complex interactions. The segmentation is further applied by dividing the service discovery process into protocol-specific discovery modules.
2Adaptability or versatility
If multiple protocol projection control services are added to support different projection protocols, then the adaptability improves, but the ease of operation deteriorates
Solution Approach 1:
The patent implements self-service by enabling automatic protocol detection and selection. The system automatically detects which projection services are available in the environment, identifies the appropriate protocol for each service, and configures the corresponding projection control service without requiring manual user input. The terminal autonomously manages the complexity of multiple protocols by performing service discovery, protocol matching, and configuration automatically.
Solution Approach 2:
The patent employs feedback mechanisms where the projection application continuously monitors the status of projection services and automatically adjusts its behavior based on service availability and compatibility feedback. The system receives feedback from the environment about available projection services and uses this information to dynamically select and switch between different protocol control services, ensuring optimal operation without user intervention.

AI summary
A method for content projection and a mobile terminal are provided. The method includes that a mobile terminal runs a local playing service, a content projection control service and at least two protocol projection control services. A first projection instruction is acquired through the content projection control service, a first content played by the local playing service is intercepted, and the intercepted first content is transmitted to first protocol projection control service. The first content is transmitted to a first projection service through the first protocol projection control service by virtue of a first projection protocol. Implementing the method and the mobile terminal may achieve compatibility with projection service of playing equipment using different projection protocols.
