Many primary and secondary schools, colleges, and vocational schools have already installed early CCTV systems, audio broadcasting systems, campus multimedia computer classrooms, campus video surveillance systems, etc., and at the same time set up expensive campus networks. Under this circumstance, in order to better realize the digital campus construction, realize the diversified teaching development goals, and normalize the campus video transmission construction, our school introduces a set of normalization of the “Aoku†independent brand launched by Polar Star. The campus network video broadcast system will build the national policy of “three links and two platforms†and strive to advance toward the development of science and education and science education.
Background introduction:
In order to better realize the goal of digital campus construction in our school, and the leaders of the school committee and committee take into account the future development and growth of our school, we will present the actual situation of our school and the normalized video teaching needs of the school to Polaris. I hope that I can work together to provide product and technical solution support for the construction of our school's digital campus.
Our school has a history of nearly ten years of school building, and has cultivated the talents of the country from generation to generation. It has a good teaching reputation. The principal and various leading organizations have discussed how to make a larger scale in our existing infrastructure. The creation of the brand effect, how to further advance, and lay a solid material foundation for the future expansion of information-based teaching applications.

According to the "Spring 2015 Semester Classroom Use Program" statistics, 126 classrooms are available for this semester, which are distributed in the teaching building 1, the teaching building 2, the comprehensive training building, the laboratory building, the multimedia teaching building and other buildings, including 4 multimedia conferences. There is a campus TV studio in the school. The conference room and studio have professional camera equipment. The campus has a fiber-optic network. The backbone network is the core of Gigabit network. The campus LAN and wireless network have been set up.
Overall design:
After the communication and analysis between the leaders of our school and the professionals of Polaris, we introduced a set of “Ao cool normal campus network video live broadcast systemâ€. In addition to the campus multimedia conference/live broadcast, this system can also Expand the application of campus network classroom live broadcast, campus IPTV network TV, campus network TV live broadcast and other applications.
The system is multi-purpose, which greatly improves the efficiency of the use of our school's equipment and systems, and can make our investment efficiency bigger.
The system has national standard development and production requirements, and has received great response from the market. Especially after the application of our school, such mature products with international standards can be combined with today's Internet application technology to broaden our school. Networked teaching, normalized teaching, and the development path of scientific education.
Process Design:
Flow chart design
Our school often has conferences/activities that need to be broadcast live, and our school campus TV station often broadcasts some school programs, so the system can enable our school to fully display and display these demand functions.
Implementation instructions:
