The application discloses a cross-device content synchronization and adaptive display method based on a multi-modal large model, and relates to the technical field of information processing and display. The method constructs a closed-loop system through three core steps: firstly, non-structured pixel flow is reconstructed into structured objects through cross-modal screen content recognition and deep semantic extraction; secondly, a platform-independent scene graph is constructed through generalized semantic encapsulation, realizing content and source hardware decoupling; finally, entity pruning, space arrangement and double-channel rendering are completed based on constraint tensor-driven topological mapping and hybrid rendering. The application breaks through the picture stream transmission limitation of traditional screen projection, realizes adaptive adaptation driven by structured semantic stream, considers text sharpness and media fluency, guarantees content consistency through a closed-loop quality control mechanism, effectively solves the rigid problem of heterogeneous device adaptation, and improves the adaptability and reliability of cross-device interaction.

The method comprises the following steps: establishing a unified time reference of an end system based on a time service mechanism; based on a unified time reference and a secure transmission constraint condition, constructing an inner-layer schedule on a kernel side through a time-aware queue rule, forming outer-layer escort on a port side through a gating list, and constructing to obtain a double-layer time slot escort structure; and constructing an adaptive guard band and phase compensation control law based on the jitter state and the alignment error of the clock, and adaptively adjusting the guard time band and windowing phase compensation of the double-layer time slot escort structure based on the control law so as to realize adaptive time slot escort and synchronous control of the end system.
