Solution for E-learning

Solution for E-learning

The solution sketching
Satellite communication is widely covered with, construction speed quickly, isn’t restrained by geographical terms from to build a station, strong group sow such a great deal of advantages as the advantage, etc. become important means for E-learning.

E-learning in the center of customer connect through high-speed digital microwave or ground circuit or Internet to the satellite network center of Goldinfo. Each E-learning can adopt high-speed form charge satellite remote station or high speed two-way satellite remote station, its Multicast download speed from teaching center to each E-learning is 6-24Mbps, Speed of spread of the reverse channel is 128-256Kbps. Satellite Remote station that all authorized can multicast lessons live telecast of the teaching center and download teaching courseware made in advance every time to the computer lies in the satellite remote station by Goldinfo Broadband Satellite Network. Being equipped with users of the remote two-way station can also carry on interactive teaching.

The compression code technology of MPEG-4 that Goldinfo develops, carrying on real-time image transmission, can be obtaining the high-quality picture at the low transfer rate (such as 256Kbps), thus reduced users' cost.

Suitable target
Solution for E-learning is suitable for the teleeducation of every university, and the instruction after class that the great teacher of education of middle and primary schools gives lessons, the cadres of Party, government and army at all levels are trained, the professional training center, English training and examination are coached, professional title and various kinds of qualifying examinations are coached etc..

Function summary
Real-time teaching scene adopt multicast to transmit:
Convey the real-time teaching scene to from end of user who is authorized by multicasting, make users in the whole country share valuable teaching resources at one time, listen to the teacher and is not limited whenever or wherever. Users can watch the video vision through the television, can watch through the computer too, can show teacher's writing on the blackboard or PowerPoint lecture notes outside the video window while watching with the computer. Users of little two-way station can also question and answer the question.

Teaching courseware is distributed by multicasting
Will make good courseware convey to the authorized user's end with multicasting in advance, users can open the courseware downloaded at any time, that is to say that it doesn't receive the time restriction to give lessons. Way this can substitute heavy workload have and spend high mailing way, can download slow network speed the way to substitute.

The customer is benefited
Utilize satellite network launch modern E-learning, can break through traditional space-time of teaching limit, give full play to the advantage of various kinds of existing educational resources, realize the rational disposition of resources.

Goldinfo broadband satellite net transmits with the speed up to 6Mbps can well support various kinds of broadband business, video transmission of the teaching scene when accurately.

Because the satellite network is transmitted by way of multicasting, compared with the situation that click to the ground circuit clicked, can reduce the transmit cost greatly.

Cooperating with the compression code technology of MPEG-4 that Goldinfo develops, carrying on real-time image transmission, can be obtaining the high-quality picture at the low transfer rate (such as 256Kbps), thus reduced users' cost.

Solution advantage
Support standard TCP/IP protocol, it is apt to bear the weight of various kinds of E-learning software and application system.

Support advanced group IP to multicast (Multicast), can multicast to different study groups, different content of courses.

Support the group to multicast the teaching mode as well as supporting interactive teaching, every teaching is clicked and can be chosen flexibly according to the need.

Carry the remote station of satellites and dispose the standard LAN interface far, can connect the computer network clicked in teaching conveniently.

The satellite system adopts 64 DES to encrypt algorithms and advanced terms to insert the technology of controlling access (CA), can guarantee the transmission with safe and reliable content of teaching.

Goldinfo’s strong application software develop team can offer powerful customer service and software development.
