key words: multimedia computer teaching network system Untitled Document overview of multimedia computer teaching network system: itstar 2000 multimedia computer teaching network system is a teaching environment integrating multimedia technology, computer network communication technology, audio and video technology and control technology, providing real-time, distortion free, full dynamic two-way transmission and remote broadcasting of image and sound, A teaching platform specially set up for the teaching field to give full play to the benefits of multimedia. Itstar 2000 integrates image, sound, text and information, fully meets the needs of modern teaching methods, provides you with a simple, easy to learn and powerful all Chinese man-machine control interface and an interactive teaching environment from individual, part to all students, and truly realizes colorful and easy multimedia computer network interactive teaching. Itstar multimedia network classroom itstar 2000 strengthens the exchange and cooperation with parks and enterprises in provinces and cities with developed new material industry. Characteristics of the system: practical and convenient operation interface: the itstar 2000 software interface adopts the simple operation mode of "point and get", which can perform the same operation on students in multiple different control areas, which is suitable for teachers to control student computers; The new map selection function is more convenient for teachers to accurately select the student machine according to the actual placement of the computer. Combination of software and hardware: itstar 2000 adopts the structure of combination of software and hardware, and achieves complete real-time effect in the transmission of image, sound and other signals. Super driving ability: itstar 2000 adopts bus topology and supports up to 256 nodes. The failure of any student computer in the network classroom will not affect the normal operation of other student computers. Flexible control selection: according to the needs of users, independent control machine, independent teacher machine or the combination of control machine and teacher machine can be selected. Super compatible performance: itstar 2000 multimedia transmission card adopts PCI interface and does not occupy any memory address and interrupt resources; The software supports operating systems such as Windows95/98, windows me/2000, Windows NT and Novell, and is equipped with dos and Windows3 The itstar control software running under X is compatible with IBM compatible computers above 486. Simple connection mode: itstar 2000 provides simple connection mode and automatic identification and allocation of workstation address 2 The function initially formed by the convergence development trend facilitates the installation, commissioning and maintenance of the system, improves the reliability of the system and reduces the failure rate. Visual status display: for each control operation on the main control interface, a very visual status icon will be reflected for the operator to see at a glance. Free setting mode: users can set the background color of itstar 2000 main control interface according to their hobbies to enhance users' participation. Strong expansion capability: users can expand VCD, recorder, projector, physical display desk and other external audio-visual equipment in itstar 2000 system as needed. At the same time, it can be connected with the Internet to enable students to catch the express train of the information age. Rich software support: in order to enable users to quickly and conveniently master the powerful functions and operation methods of itstar 2000, a multimedia demonstration CD is presented free of charge. Ensure that there is no year 2000 problem. System function: image broadcasting: it can broadcast the pictures on the teacher's screen (such as Cai, text, picture, animation, etc.) to individual, some or all students in real time. Sound broadcasting: the teacher can broadcast the sound source to individual, some or all students. At the same time, it can also realize the remote dialogue between teachers and students. Interactive teaching: teachers can use the keyboard and mouse of the control machine to conduct remote interactive dialogue and operation on students, so as to realize remote guidance teaching. Electronic hand raising: students can press the [scrlock] key on the keyboard to raise their hands electronically, and their help information will appear on the main control interface. This function can also realize electronic rush answer. Screen monitoring: any student's screen can be monitored through the control machine, and some or all students' screens can be monitored in turn. Sound indication error monitoring: teachers can monitor the voice of any student, and take turns to monitor the voice of some or all students.
