Examination System: has a variety of test grouping methods (AB type) for the listening test and the spoken English test.
Test Analysis System: The system has the intelligent test paper generation guide, the rich exam papers library, the automated scoring system with detailed test paper analysis and the perfect test results graphical analysis and exam information management system provide schools with a feasible professional examinations implementation environment.
Class Management: Teachers can "add" or "delete" class, student ID, set up the seat number information, to enable them to conduct class management.
Billing Management£ºIt enables the teacher to view and manage the students¡¯ payments, renewals and other expenses; teachers can conduct renewals by classes or by student¡¯s ID.
Device Log Management£ºThe system automatically records the start and end time of the students¡¯ using terminals and reflects the equipment¡¯s using situation, it is easy to find those responsible for causing equipment failure.
Material Log Management£ºDuring the process of the student¡¯s self-learning, the system automatically records students¡¯ learning content (name and learning time of the data on demand) to facilitate the monitoring of the students¡¯ learning.
E-lesson Preparation£ºTeachers make courseware through the data management; in the class, teachers can directly calls to use the courseware they prepared to facilitate their teaching process.
Data Management£ºTeachers can add, delete, sort and operate material management.
Terminal Reset: The system automatically checks and recovers the fault.
System Configuration: to freely configure the classroom¡¯s seating to facilitate future changes.

DH-100EK Student Terminals¡¯ Main Function
Main Function:
DH-100EK is a network-based language learning system. It is a combination of ATM network technology based professional all digital language lab and Ethernet-based computer room, conserve resources for the user. Meanwhile, the language lab and the computer room can be used independently and does not affect each other, even if the computer room have problems, it does not affect the use of the language lab.
The sound quality of the language teaching is perfect, the voice is clear; the simultaneous transmission has no fracture. Enables the system will not collapse when processing large-scale oral discussion. The video broadcasting teaching uses the specific video HUB with differential signal transmission makes audio and video synchronization delay of only 1.2ms. It has effectively solved the problems of image ghosting, jitter, and mosaic and so on. Ensures that the images are clear, stability is high, and the transmission distance is long. Student terminals use student computer monitor to receive video broadcast.
DH-100EK language learning system also has the following features:
1, it has no requirement for the student terminal computers¡¯ hardware configuration level2, the system boot faster
3, good video broadcasting effect and good sound quality of multiple people talking
4, higher data storage safety for multiple people recording
5, no noise when conduct language teaching
6, easier class management
7, safer and of small workload of maintenance
8, low energy consumption
9, long lifespan
DH-100EK student terminals¡¯ main features are: digital recording, text along with reading, repeated listening, audio on-demand, volume control, bookmark play, variable speed play on demand, AB play, electronic hands show, intercom demonstration, listening test, line out, terminal reset , sub-track recording and playback, headphone & microphone unit intelligent test, the centralized boot and shutdown control of the students¡¯ computers.
In addition to the above mentioned student terminals features, also can realize features of VOD on demand, Internet browsing, upload and download, Internet online testing etc.
DH-400K Student Terminals¡¯ Main Function
Main Function:
Student terminal apply with dual-core processing and control system and screen sub-display system, an FPGA chip integrates two processing cores, and a terminal can connect two keyboards for two students independently use while does not affect each other. The wiring of the system is simple and convenient to install, cost-effective; "a dual display screen," one monitor not only can be used as the equipment from which the two students can together enjoy or separately enjoy the video programs at the same time, but also can be two students¡¯ text-on-demand display device on their own, moreover, one screen are divided into two, the independent sub-display screen does not affect each other.
