The first wonderful flower-NewClass DL500K

As we all know, in the development process of language laboratory products, in order to meet the demand for multimedia program source broadcasting teaching, a so-called "two enjoy one" type product has evolved, which specifically refers to adding one in the middle of the double table of two students A standard computer monitor, shared by two people, mainly used for teacher computer screen broadcast or program source broadcast of external multimedia equipment at the teacher's end (such as DVD, video tape, video booth, etc.). On the monitor shared by the two. With the popularization and application of this functional requirement, the word "two enjoy one" has become a specific proper noun in the field of language laboratory products.

Traditional "two enjoy one", single function
In the traditional analog language laboratory products, each student unit is equipped with a language learning terminal with a cassette tape recorder, which is generally not equipped with a display. The "two enjoy one" upgrade of these products is in two students Add a shared display in the middle of the bit, and then use the VGA splitter and VGA cable to complete the video broadcast function.
The introduction of digital technology has accelerated the development process of language laboratories. In the new digital language laboratory products, the teaching resources are digitized and acquired and shared through the network. The more prominent change is that digital products provide students with networked “independent learning. "Function, this requires that in addition to the headset microphone and small operation panel used for" listening "and" speaking "training on the equipment configuration of the student unit, it is also necessary to add support for" reading "," writing "and" seeing " Device: monitor.
Digital language learning terminals are currently divided into three categories on the market: popular, mid-range, and high-end. Popular student terminals are usually equipped with a 5 ″ small LCD screen, which can display about 600 English characters or 300 Chinese characters, and realize the functions of audio on demand and text on demand; while middle and high-end digital language learning terminals are usually equipped with standard computers The monitor, one per person, in addition to audio on demand, text on demand and other functions, also provides VOD video on demand, online courseware on demand, movie dubbing, simultaneous interpretation, Internet access and other professional language training functions.
The popular digital language learning terminal meets the common teaching and autonomous learning requirements due to its moderate price. It has been adopted by many schools in recent years, but the 5 ”small LCD screen equipped with the student terminal of this product can only display characters , Can not display video images, so the same solution under the concept of "two enjoy one" is also used to make up, that is: add a standard computer monitor in the middle of the two student desks to complete the video broadcast teaching. "Two enjoy one" "This term is naturally used in digital language laboratory products.
Has the concept of "two enjoys one" entered the digital age in this way?
no! The ever-changing technology always brings unexpected surprises to people. A wonderful flower makes people's eyes shine: a NewClass DL500K newly developed by Beijing Dongfang Zhenglong Digital Technology Co., Ltd., named "Gemini", the digital "two enjoy one" "The new generation of products was born, which gave new meaning to the concept of" two enjoy one "for language labs in the digital age:
You are half, I am half, and the "Two Enjoy One" display is divided into two halves.
The display in the traditional "two-for-one" concept has only one function: that is, passively displaying video broadcast images. In the case of teachers not performing broadcast teaching, the display becomes a display, which is a waste of resources. Under the new concept, the "two-enjoy-one" display becomes passive and active, the screen is separated from the middle, and one person is half. Equipped with standard computer keyboard and mouse, Chinese input and mouse operation are realized. The display interface adopts Windows style, and the display area of ​​each window is up to 600x400 pixels, which provides learners with a new visual field. This innovative invention not only replaces the 5 "small LCD screen of the original popular terminal, but also brings a new effect to the traditional" two-for-one "concept of the display, which has achieved 100% utilization.
The world's first one
The DL500K developed based on NewClass's world's first "embedded multi-user concurrent operating system" has further sublimated the concept of "two enjoy one"-not only the display enjoys two, but also the student terminal equipment also realizes two enjoy one, that is, one terminal equipment It supports the connection of two sets of mouse and keyboard, allowing two students to operate independently without interfering with each other. For example: when the student on the left uses the mouse to browse the electronic text, the student on the right can use the mouse and keyboard to operate the audio-on-demand. When two students at the same table order listening learning materials, they do not interfere with each other. The two-for-one enjoyment of terminal equipment reduces the overall cost of the system by 1/2, and achieves the best cost performance.
Powerful value for money
Because the DL500K terminal core adopts the current world's top embedded CPU processor: Intel PXA270, the professional functions of many middle and high-end digital language laboratory products in the past can be realized on the DL500K: digital dual-track recording, recording MP3 generation, synchronization Voice interpretation training, U disk download, spoken chat room, Chinese input, etc ... It is really "value for money".
NewClass Gemini DL500K-This wonderful flower that was first opened in the garden of the digital language learning system has been blooming in the surprise of users.
