Ministry of Education in 2008 highlighted the work to "actively develop modern distance education in primary and secondary schools, efforts to promote classes in communication, dignified, and let the majority of primary and secondary students access to quality education resources." Guangzhou Ying Jia help school "classes in" the project construction, the "pass classes in" building complex distributed applications in the classroom, the status side, the introduction of a "good integration classes in English through the system" as the core of the overall construction of multi-media teaching solution program. The program allows teachers to easily every application of multimedia teaching equipment and educational resources to help school construction, educational resources from the regional platform for every school, every class of students can have access to quality educational resources to promote student learning information and modernization of school education. "Good integration of classes in English communication systems" embedded architecture, in addition to the regular features with ordinary computers, but also melt in the control, multimedia, digital video and audio broadcast and other powerful features in one, not only added to replace the traditional computer in the control of the modes and a COD courseware on demand, VOD VOD, AOD audio on demand, Internet browsing, resource library construction assisted teaching toolbox, schedule management and many other features. Can be achieved by extending the two-stream system of teaching, demonstration teaching, teaching evaluation, network broadcast, digital video surveillance, electronic invigilator and other functions. D age classes in multimedia communication solutions for the school building as a whole to construct a full multimedia classroom multimedia teaching and learning environment, so that the network really into the classroom multimedia teaching. integration of high technology advantages, integrated design. Built-in PC, in control, amplifier, speakers, 2.4GHz digital wireless microphone, 320 million pixels-kind booth. Standard PCx86 architecture, embedded structure. The work of the existing embedded system stability, environmental adaptability, good benefits of device independence, but also to achieve mainstream PC capabilities. Built-in switch, the memory can be expanded, to an additional hard drive, CD-ROM. strong central control functions, independent power supply, 24-hour stable operation. Meet different needs. For different network architectures, the system can be used both unicast and multicast transmission, greatly reducing the network resources occupied by a small propagation delay. The control interface, rich, and strong expansion. Digital Realization of the system, speaker each classroom could be used for classrooms. Across routing, cross-VLAN, support for multicast protocols. highly integrated, multi-media teaching, audio and video transmission, equipment management and control functions, integrated implementation, simple to use. two-way video server can be extended. VGA hardware scalable real-time acquisition.
