Newly defined digital language room
Digital Language Room Market Status Digital With the rapid development and maturity of digital technology, digital language rooms with multiple technical solutions have been launched. In order to make users have more understanding of the digital language room, we make a more comprehensive introduction to the digital language room. The first type: basic type: The second type: large screen display type: The third type: dual network integration type: Fourth: Embedded network computer type: Height Adjustable Kitchen Sink wheelchair accessible kitchen sink,accessible kitchen sink,handicap kitchen sink,disabled kitchen sink,barrier free kitchen sink Suzhou Uplift Intelligent Technology Co., Ltd , https://www.up-lifting.com
There are four types of language rooms:
Adopt 5 inch LCD screen (320X240 dot matrix display 300 Chinese characters) and student operation keyboard. This type of product adds digital recording, AOD audio on demand and simple text on demand interactive functions on the basis of the analog language room.
Using 15-inch display. On the basis of the first basic type, the large-screen text display, text input and video broadcasting functions are added.
The technical solutions adopted by the above two types of products cannot achieve video streaming on demand and system expansion. It can not meet the needs of the interaction between students in modern language teaching, and is a transition product between analog and digital.
The combination of basic and general computer network classrooms can realize AOD, VOD, text on demand and video broadcasting, audio and video streaming on demand, browsing campus network, Internet and other functions. This type of product was launched in compliance with the reform plan for foreign language teaching launched by the Ministry of Education in 2004. Each manufacturer has added a general computer network to the digital language room designed by its original technical solution to achieve Internet access.
As we all know, the general-purpose computer is very powerful, but it has the problem that everyone has a headache, that is, virus infection and hacker attack. Therefore, all manufacturers had to use hard disk protection cards to prevent the invasion of viruses and hackers. In order to comply with the foreign language teaching reform program implemented by the Ministry of Education in 2004, the increase in the general computer network system that enables students to browse campus networks, the Internet and other functions not only caused users difficulties in equipment maintenance and installation (increased power consumption increased the user ’s Power supply load, even the original power supply line needs to be modified). At the same time, because each student terminal equipped with a general-purpose computer (PC) in the language room is expensive, this greatly increases the investment in the construction of the language room, and it is bound to affect the number of language room constructions when the investment scale is approved.
â‘ , basic type of embedded network computer; products based on Ethernet, embedded system, ARM microprocessor, embedded operating system software technology design. It can realize AOD, VOD audio and video streaming on demand, video broadcasting, text on demand, text editing, digital recording, and corresponding learning functions. It supports multiple media file formats and third-party teaching software.
â‘¡, Embedded network computer access type: products based on Ethernet, embedded system, ARM microprocessor, embedded operating system software technology design. Can realize AOD, VOD audio and video streaming on demand, video broadcasting, text on demand, Word text editing, digital recording, corresponding learning functions, browsing campus network, Internet and other functions (students can access the Internet without a PC) with anti-virus and anti-virus Hackers, support for multiple media file formats such as MP3 and third-party teaching software, and the student-side USP interface is used for uploading and downloading files from U disks.
It has a good development space, with the basic characteristics of standardization, networking, openness, etc., and the development space of using embedded technology in the digital language room is extremely vast. Program. The embedded computer has the advantages of small size, light weight, low cost and high reliability.
