US 2026/0227947 A1 · PROJECTION SYSTEM, METHOD, AND APPARATUS, STORAGE MEDIUM, AND COMPUTER PROGRAM PRODUCT

Abstract

This application discloses a projection system, method, and apparatus, a storage medium, and a computer program product, and belongs to the field of computer technologies. The method includes: A source device sends a UI structure and UI attribute data of a projection area to a destination device. In this way, the destination device can construct, reconstruct, render, and display a corresponding projection area based on the UI structure and the UI attribute data at a UI layer. In this solution, the source device does not need to perform video encoding and transmission after rendering an image, thereby reducing power consumption of the source device. The source device does not need to send user-related data to the destination device, thereby reducing a risk of leakage of user privacy data.

Dependent claims

A projection system, wherein the system comprises a source-end projection module and a destination-end projection module;

the source-end projection module is configured to send a user interface UI structure and UI attribute data of a first projection area to the destination-end projection module, to project the first projection area from a source device on which the source-end projection module is located onto a destination device on which the destination-end projection module is located, wherein the UI structure indicates a layout relationship between a plurality of UI nodes in the first projection area, and the UI attribute data indicates a rendering-related attribute of each of the plurality of UI nodes;
and
the destination-end projection module is configured to:
receive the UI structure and the UI attribute data, and display the first projection area on the destination device based on the UI structure and the UI attribute data.

1 more element

A projection method, applied to a source device, wherein the method comprises:

sending a user interface UI structure and UI attribute data of a first projection area to a destination device, to project the first projection area onto the destination device, wherein
the UI structure indicates a layout relationship between a plurality of UI nodes in the first projection area, the UI attribute data indicates a rendering-related attribute of each of the plurality of UI nodes, and the UI structure and the UI attribute data are used to display the first projection area on the destination device.

A projection method, applied to a destination device, wherein the method comprises:

receiving a user interface UI structure and UI attribute data of a first projection area that are sent by a source device, wherein the UI structure indicates a layout relationship between a plurality of UI nodes in the first projection area, and the UI attribute data indicates a rendering-related attribute of each of the plurality of UI nodes;
and
displaying the first projection area based on the UI structure and the UI attribute data.
