The invention has the beneficial effects that:

by using the uniform service interface layer, the signal calling complexity of the upper application program can be greatly reduced, and meanwhile, the system coupling degree is reduced and the stability is improved. By sharing the display content across processes through the virtual bit planes, a large amount of picture content can be efficiently displayed simultaneously on the same display interface, and the picture switching and management are easy. Great convenience is brought to the development and design of the upper application program. Based on the plug-in service aggregation, the service scope (which service is used and which function is provided) can be conveniently and flexibly authorized, and the service can also be provided for a group of application programs to share the functions of the service infrastructure.

The invention has the advantages of greatly reducing the difficulty of upper application development, improving the performance and stability of an upper application system, reducing the construction cost of an integral conference/training system and the like.

Detailed Description

The invention is further described below with reference to the figures and examples.

As shown in fig. 1.

A signal aggregation service interface method based on virtual bit plane sharing technology, as shown in figure 1, aggregates various contents such as wired/wireless display signals, program windows and documents, and realizes multi-content efficient display and control management, which comprises the following key points:

the method comprises the steps that firstly, multiple services are aggregated, the multiple services are started in a background according to configuration based on the multi-process capability of an operating system, each service provides different functions, and the services are independent and do not interfere with each other;

and secondly, providing a uniform service interface layer, wherein the service interface layer and the service carry out cross-process communication, the invention adopts a Named pipe (Named Pipeline) mode to carry out bidirectional signaling interaction with each service process, and a data transmission format is organized by adopting a Json mode.

And thirdly, providing a service interface API to an upper application program, registering the application program on the service interface, receiving various messages of the service, analyzing the message content, and displaying and feeding back on the UI.

And fourthly, aiming at the display of the content (including contents such as screen projection pictures, videos, pictures, documents and the like), the service program provides cross-process sharing textures based on a display memory plane, and the application program can directly share and display the content and carries out various animation interactions based on a 3D rendering engine.

And fifthly, aiming at different contents, different control interfaces are provided, so that different resources can be conveniently controlled.

Taking local picture playing as an example, a specific implementation process is described from the perspective of an application program:

step one, searching picture service through a service interface, and starting the service and registering a current application program if the state is not started;

secondly, enumerating resources in the U disk by the application program, selecting a picture to be opened, opening a command of the picture through the service interface, transmitting the command into a picture path, returning a unique resource ID by the service interface, and transmitting the command to the service process in an asynchronous mode;

thirdly, the picture service process opens the appointed picture, if the opening is successful, the picture information (resource ID, path, resolution, bit depth and the like) is cached in the service, and a shared GPU video memory bit plane is created;

step four, the service process informs the result of opening the picture of the service interface, returns error information unsuccessfully, registers the bit plane handle after success and broadcasts a resource change message (adding) to the service interface;

fifthly, through a service interface API, the application program receives the message of image opening, analyzes the message to obtain a bit plane handle, and displays the bit plane handle on a page;

and sixthly, when the picture needs to be closed, transmitting the resource ID through a service interface API. And after receiving the instruction, the service program closes the picture resource, releases the display memory plane and updates the cache information in the service.

And seventhly, broadcasting the resource change information (removal) to the service interface by the service, and synchronously refreshing the display of the UI after the application program receives the information.

The present invention is not concerned with parts which are the same as or can be implemented using prior art techniques.
