Embodiment Construction

[0039] The present invention provides a multi-program simultaneous display method and system based on Windows CE. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The present invention provides a multi-program simultaneous display method based on Windows CE, which creates multiple virtual pages in the memory of the server (that is, virtualizes one hardware overlay resource into multiple), and each page is an overlay for the client page, the server operates the final hardware overlay page according to the attributes of each layer. The server operates an actual overlay resource, but for the client, each client can access multiple overlay resources, realizing virtual multiplexing of resources.

Abstract

The invention discloses a multi-program simultaneous display method and system based on windows CE. The method comprises the steps that A, an interface layer receives requests for virtual overlay layers of all client sides, and data which are sent by the client sides and need to be displayed are packaged and sent to a drive layer; B, a server side receives the packaged data in the drive layer and sets up virtual overlay layers of all the client sides by utilizing the packaged data; C, the server side synthesizes an image of a composite overlay layer according to the information of the virtual overlay layers of all client sides, and the image is refreshed to be displayed on a physical page. By means of the method and system, each client side can access multiple overlay resources, and virtual reuse of the resources is achieved. Under the condition that the overlay resources are not sufficient, multiple programs do not need to be complexly matched, all application programs use the uniform interface to access the resources, the occupancy conditions of the resources do not need to be considered, and transplant of the programs is facilitated.

Description

technical field [0001] The invention relates to the field of image display, in particular to a multi-program simultaneous display method and system based on Windows CE. Background technique [0002] Windows CE (or WinCE for short) is the foundation of Microsoft's embedded and mobile computing platform. [0003] In the interface design of the vehicle-mounted multimedia device of the WinCE system, it is often necessary to display some content that needs to be placed on the top, and multiple programs may need to be displayed at the same time. Generally, the overlay (overlay) technology is used (Overlay technology is a feature of Microsoft’s DirectDraw technology. In hardware resources With the support of the image display, it can improve the efficiency of image display and achieve functions such as layer composition), but the hardware overlay resources are limited, and it cannot meet the requirements of multiple applications using the overlay resources for interface design at t...
