10. MAIN DATA,s.r.o.. snímok 9 Satellite in Tele Education in comparison to land line online education (TV like Video). Advantages for Distance Education: Wide geographical coverage Broadband Last Mile solution True multicast environment Quick installation anywhere High quality streaming video Inexpensive one-way receivers QoS implemented Disadvantages versus to land line: Higher bandwidth costs Higher two-way terminal costs

11. MAIN DATA,s.r.o.. snímok 10 How SMART EDU addresses disadvantages of sat. communication Disadvantages versus to land line: 1) Higher bandwidth costs Satellite Bandwidth is used Only at forward Multicast channel so bit higher costs are split among larger number of Learners. In consequence satellite bandwidth presents fraction of land-line costs. 2) Higher two-way terminal costs SMART_EDU integrates less expensive Interactive channel media like Internet, ISDN etc, so there are receive only terminals needed. DVB receivers at cost level of 200 Euro represent inexpensive mass consumer market electronics.

12. MAIN DATA,s.r.o.. snímok 11 How SMART_EDU benefits from the Satellite power. Wide geographical coverage It allows to bridge very large distances Continent. Organizationally it allows to overcome critical mass limit for highly specialized professions Broadband “Last Mile” solution SMART EDU delivers TV like quality video 1- 30 mbit/s directly to end-users at guaranteed bandwidth QoS True multicast environment SMART EDU allows to multicast traffic on-air, re-using the same capacity for unlimited number of users. Quick installation anywhere Digital TV sat. dish is sometime quicker to install as to wait for land lines from local PTT. High quality streaming video Allows most natural kind of Distance Education and eliminates the need to prepare electronic syllabus. So even ICT not experienced Lectors can provide their Lectures in old way. Inexpensive one-way receivers SMART EDU is based on Digital TV receivers ranging from 200 Euro. It allows mass use.

13. MAIN DATA,s.r.o.. snímok 12 SMART_EDU technology SMART_EDU is based on two broadly available communication media Digital TV and Internet where Digital Television contributes BROADBAND one-way capacity and QoS on one side and Internet contributes INTERACTIVITY to Digital TV on another side. 1) DIGITAL TELEVISION (DVB MPEG-2) for TV like quality QoS Streaming Video distribution in various formats from MPEG-2, MPEG-1, MPEG-4, H.263 2) Internet (IP) for Interactive channel (or ISDN) 3) Contribution link reflecting local possibilities: ATM, Frame Relay, SCPC, RCS, DSNG, ISDN etc., IPV6 in future

14. MAIN DATA, Ltd. 8/27/201513 1) Lector STUDIO Video & Audio encoding: Low Delay, Full Screen MPEG -2 H.263 Functions: Video camera PC screen or other sources (microscope, ECG, CPT etc.) Video compression Organize, sort feedback from learners Manage Didactics delivery Simultaneous translations CA system

15. MAIN DATA, Ltd. 8/27/201514 2) Contribution Link from STUDIO to up-link Alternatives: ATM, Frame Relay ISDN 2 mbps Multiplex xISDN 64 kbps connection Future IPv6 QoS Internet Satellite (DSNG, DVB SRC, VSAT, SCPC etc) Functions: Eliminate the need of LECTOR travelling Numerous Organizations may share 1 satellite up-link

16. MAIN DATA, Ltd. 8/27/201515 4) SATELLITE Native Multicast Functions: Multicast to entire continent bypasses land line Internet Broadband up to 60 Mbit/s directly to Learners (offices, homes) High Speed Asymmetric IP Streaming video, audio, files etc into multiple learner sites No Risk of Servers PEAK load hours Location independent (travelling professionals) 3) SMART_EDU uplink

17. MAIN DATA, Ltd. 8/27/201516 Single user platform: A) PC based 1) C ++ 2) JAVA based 3) WEB Based B) DVB (MPEG-2) 1) non MHP 2) MHP based 5) Learner site Videoconference classroom: Data Projector Interactive return channel: Internet Chat, Phone, ISDN to up/link, Satellite return SRC etc.
