Preset Multimedia Connection for Synchronous Cross-Device Display

The patent establishes preset communication connections between smart devices in advance, before actual data transmission is needed. This preliminary action allows devices to be pre-paired and configured, so when data needs to be transmitted, the connection is already in place and can be activated immediately without going through complex connection processes, thus resolving the contradiction between connection reliability and transmission efficiency

By pre-establishing communication connections between devices before actual use, the patent eliminates the time-consuming connection setup process during data transmission. The preset connections are configured in advance with stable parameters, ensuring both connection stability and rapid activation when needed, thus resolving the contradiction between connection stability and time-efficient performance

The patent enables devices to automatically utilize preset communication connections for data transmission without requiring users to manually configure connection parameters or select transmission methods. The system self-manages the transmission process by automatically routing data through the appropriate preset connections, thereby improving user convenience while maintaining broad compatibility through standardized connection protocols
