Embodiment Construction

[0034] The main ideas of the embodiments of the present invention are as follows: firstly, the client sends a physical device object (PhysicalDevice Object, PDO) creation request to the video device driver module (USB camera driver); then, the video device driver module creates the PDO, and The operating system loads a virtual video driver module (Virtual camera driver) for the PDO created; at last, the video device driver module obtains video data from the video device, and the virtual video driver module obtains the video from the video device driver module data, the video device driver module and the virtual video driver module respectively return the video data to the client.

[0035] Included in the present invention are client, video device driver module, virtual video driver module and operating system, and client includes PDO creation request and more than one application program, and this application program, video device driver module and virtual video driver module ...

Abstract

The invention discloses a method for accessing a video device. The method includes: a client sends a physical device object PDO creation request to a video device driver module; the video device driver module creates a PDO, and an operating system loads a virtual video driver module for the created PDO The video device driver module obtains video data from the video device, and the virtual video driver module obtains the video data from the video device driver module, and the virtual video driver module and the video device driver module return the video data respectively to the client. Through the present invention, multiple application programs access one video device at the same time, and video data can be provided to multiple application programs in the upper client at the same time, so that the user experience is better. The invention also discloses a system for accessing video equipment at the same time.

Description

technical field [0001] The invention relates to data transmission technology, in particular to a method and system for accessing video equipment. Background technique [0002] At present, the process for the client to access the Universal Serial Bus (USB) video device on the operating system side through the application program is exclusive, that is, in the system, only one application program can access the video device at the same time, and then obtain video data. For example, when a user uses instant messaging software for video chatting, only one video software application program can be used to access the video device at the same time. But, along with the development of network technology, most users may run at least two instant communication softwares simultaneously, or other multimedia softwares, therefore, can't realize that a plurality of application programs visit a physical Video equipment, and it is impossible to provide video data to multiple upper-layer applic...
