Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that in the prior art, when a user uses a certain type of terminal, he needs to manually search for ActiveX components corresponding to the type. If there are too many types of video terminals, it may be difficult to search for matching ActiveX components. , resulting in poor scalability of the video terminal system to different types of video terminals

Embodiment 1

[0032] Such as figure 2 As shown, as an embodiment of the present invention, a video terminal control method based on ActiveX polling includes the following steps:

[0033] S1: Sorting and numbering different types of ActiveX components;

[0034] S2: receiving a request for controlling the video terminal;

[0035] S3: According to the received request for controlling the video terminal, load the ActiveX component sequentially according to the number and ask the video terminal to request to establish a control link;

[0036] S4: If the message that the video terminal has responded to the link is received, the inquiry is terminated; if the message that the video terminal refuses the link is received, the inquiry of the ActiveX component of the next number is performed until it matches .

[0037] According to the ActiveX polling-based video terminal control method, different types of ActiveX components can be sorted and numbered through the above steps, so as to facilitate th...

Embodiment 2

[0039] As an embodiment of the present invention, on the basis of the above-mentioned embodiment 1, in step S4, after receiving the link rejection message fed back by the video terminal, the step of destroying the information of the activeX component with the current number is also included.

[0040] According to the ActiveX polling-based video terminal control method, after receiving the link rejection information fed back by the video terminal through the above steps, the information of the ActiveX component with the current number is destroyed, which can save the matching steps and prevent the matching from falling into a loop.

Embodiment 3

[0042] As an embodiment of the present invention, on the basis of the above-mentioned embodiment 1 or 2, in step S1, the ActiveX components are sorted and numbered according to self-definition. It can also be sorted and numbered according to a fixed order, such as sorting in the order of adding, and the purpose of the present invention is also achieved.

[0043] According to the ActiveX polling-based video terminal control method, ActiveX components can be sorted and numbered according to self-definition; or automatically sorted and numbered according to the type of ActiveX components to meet different sorting requirements.

Abstract

The invention provides a video terminal control method and a video terminal control system based on ActiveX polling. The method comprises the steps of sequencing and numbering ActiveX components of different types for conveniently identifying the ActiveX components; sequentially loading the ActiveX components for inquiring a selected video terminal about requesting to establish a control link according to serial numbers; judging whether the first loaded ActiveX component is matched with a video terminal or not, if not, carrying out matching of the ActiveX component of the next number with the video terminal until one of the ActiveX components is matched with the video terminal. Automatic matching of the ActiveX component and the selected video terminal is realized, the step of manually matching is omitted, the support of the system for the video terminals of different types can be enhanced by automatic matching, and the expansibility of the system is greatly improved.

Description

technical field [0001] The invention relates to a conference terminal control technology. Specifically, it relates to an ActiveX polling-based video terminal control method and system. Background technique [0002] With the continuous development of Internet technology, the bandwidth of the Internet is getting wider and wider, and it is becoming more and more common to insert multimedia effects, interactive objects and complex business control programs into web pages. In the WEB field of B / S (browser / server) architecture, ActiveX components can be easily applied to web pages or desktop applications. ActiveX technology is also gradually used, such as: video on demand, video surveillance, equipment control, information communication and other fields. Real-time performance, high security, and complexity of WEB applications can be realized by using ActiveX components, and the interactive experience of WEB can be enhanced in the fields of video conferencing and video surveillan...
