| With the rapid development of computer science and technology, high-definition video conferencing system in various fields gradually popular, especially in our country of the communist party of the eighteenth big spirit through video conference to carry out study, since our country entered the stage of rapid development of video conference system, further development to all walks of life. Video conference with the development of optical network, also more and more high, quality of video conference and video conference system to achieve good results, the video conference room supporting design is indispensable, small and medium-sized video conference room, usually deployed a hd video camera is enough, but space is big big main video conference room often need to deploy two or three with the function of ptz high-definition cameras, so that the venue for different angles of shooting (panoramic, features, etc.), so you need to staff to control the camera haeundae, timely and traditional ptz control is implemented by ptz keyboard, need to connect the power cord and fixed in one place for a transmission line operation, use convenient and flexible enough.Traditional high-definition video conferencing system is using infrared remote control function of the remote control for special purpose, but with smart tablets (Android, IOS) spread, smart tablet interface is clear and easy to understand, simple operation and easy to use, high definition video conference system based on intelligent tablet has a tendency to replace the traditional infrared remote control remote control. After the corresponding program development, video conference system as well as the camera haeundae control can be integrated into an intelligent remote control, remote control for video conference system is much more convenient and flexible to control.In this paper, the implementation of the CoolView based video conference system, the system also chose the solution in the remote control terminal, the difference is the remote control is no longer a special equipment, but can in general installed on mobile devices, such as mobile phones, tablet using a software. CoolView video conference system, as a national project "next generation Internet mass high-definition video conferencing system application demonstration" part of the research and development, the author is mainly responsible for ptz control function of the system work, the design and implementation of terminal by QT and c++development on local ptz control function, and the increasing on the android remote control ptz control function module, with the help of a WIFI network, terminal remote agent as intermediary, realize the remote control of the camera haeundae remote control. This paper has been implemented well as well as local control and remote control functions, and supports a variety of different yuntai control protocol, has been in CoolView used in video conference system, to provide users with convenient control services, has a good practical significance. |
