Slide 4

Internet Streaming An Internet information exchange strategy that permits the client to see and hear sound and feature documents without extensive download times The host or source “streams” little bundles of data over the Internet to the client, who can get to the substance as it is gotten E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 5

Software We Used We utilized applications from RealNetworks.com to encode and serve our classroom-based gushing feature RealProducer (now Helix Producer) to catch and encode feature RealServer (now Helix Universal Server) to circulate the feature RealPlayer and RealOne Player to view spilling feature E.

Slide 10

Video Was Delivered Directly to the Student’s Desktop We didn\'t telecast to studios or PC labs where understudies would need to accumulate to participate—delivery was straightforwardly to the student’s desktop E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 11

Purpose of the Study: 1 To distinguish levels of planning and bolster (gear, programming, staffing, offices, foundation, and so on.) important to deliver and convey live classroom-based Internet spilling feature with ease to understudies at home or in their workplaces Remote understudies would offer their remarks and inquiries through a synchronous live visit session E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 12

Purpose of the Study: 2 To check whether we could widen access to classes by offering them over the Internet To figure out the amount of showing systems expected to change to be fruitful in this environment To make chronicled documents accessible to understudies for review on interest E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 13

Purpose of the Study: 3 To check whether we could enhance class substance and reviewing so as to show routines chronicled documents To check whether we could enhance regulatory choices by investigating filed records To gage understudy reaction to instructional conveyance to the desktop at home or in an office E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 14

Purpose of the Study: 4 To check whether classes could be telecast from any grounds classroom area and not be attached to a studio; if fruitful, more classes could be offered to remote understudies E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 16

Video Encoding Rates RealProducer can encode feature records for gushing to any blend of the accompanying customers: 28.8Kbps or 56Kbps for dial-up modems 64Kbps for single or 128Kbps for double ISDN lines 150Kbps for neighborhood 256Kbps, 384Kbps, or 512Kbps for quicker LANs, link associations, and computerized endorser lines (DSL) E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 17

Encoding Rates and File Size Triple stream feature documents encoded at 56Kbps, 150Kbps, and 256Kbps utilization 3.9 megabytes of capacity for every moment Stream to the viewer at the most elevated dependable association, commonly 34, 150, or 225Kbps This multistream gives a decent adjust of sound and picture quality and targets dial-up, LANs, and broadband later on we may encode at 56, 150, and 384Kbps for playback at 34, 150, and 350Kbps E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 18

Connections: LAN/Broadband Local Area Network (LAN) and broadband associations (link, DSL) are plainly better Video encoded at 256Kbps is gotten at 225Kbps Video encoded at 384Kbps is gotten at 350Kbps Video encoded at 512Kbps is gotten at 450Kbps Sound and feature are both great Acceptable for movement, detail, and close-up work E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 19

Connections: 56K Dial-up 1 Streaming feature encoded for 56Kbps dial-up modems is gotten at 34Kbps Sound is great Picture is not about on a par with 150, 225, or 350Kbps streams Video is uneven and there may be incessant rebuffering if there is system clog More like a slide show than a film E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 20

Connections: 56K Dial-up 2 May not be worthy for classes or demos including movement, detail, or close-up work May be adequate for dialog based classes with little development May be satisfactory for substantial picture PowerPoint presentations with next to zero liveliness E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 21

Connections: 28.8K Dial-up 28.8K modem association is hazardous Should be utilized as a gushing feature transmission speed in constrained circumstances Little movement in presentation No requirement for point of interest or close-up work No requirement for synchronization of sound and feature E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 23

Results: 1 It’s conceivable to make and convey great quality restricted data transfer capacity (<512Kbps) Internet gushing feature with constrained staff requiring little to no effort when utilizing programming from RealNetworks.com and off the rack (Radio Shack) equipment E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 24

Results: 2 Instructor’s showing style and course content must be amiable to this conveyance technique on the off chance that it is to be effective Instructors don’t need to change their classroom routines all that much to succeed with Internet gushing feature television; long stretches of preparing seem, by all accounts, to be superfluous E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 25

Results: 3 Preparation, practice, and auspicious circulation of supporting material are discriminating to fruitful gushing feature presentations Instructors discovered evaluating chronicled spilling feature documents to be a profitable device for enhancing class substance and showing techniques E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 26

Results: 4 Faculty workload increments in this environment, however not almost as much as in an offbeat content or media based web showing environment Time spent on planning and creation is less with spilling feature, however after generation work may be all the more, contingent upon the personnel member’s choices on the amount to do after class E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 27

Results: 5 Student reaction to survey classroom presentations (both live and documented) was for the most part ideal; the speedier the Internet association, the better the understudy experience Student reaction to live classes was by and large great, even from those with generally moderate 56Kbps dial-up associations E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 28

Results: 6 Students need more classes offered by means of spilling feature in the event that they have entry to quick associations like Oceanic Cable’s RoadRunner administration E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 29

Results: 7 Students thought review chronicled gushing feature class documents on interest (nonconcurrently) was as compelling from an instructional perspective as taking part in the live class (synchronously), gave they could then cooperate with the teacher by means of email, visit, or videoconferencing Asynchronous conveyance with a planned online class meeting segment could build access E. Bloom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”

Slide 30

Results: 8 Archived records could be seen when system activity was low, or, filed documents could be conveyed on CDs which would take out conveyance issues connected with moderate system associations or system congestion—this could be a shelter to less created zones with frail bases E. Blossom, “Low Cost Narrow Bandwidth Classroom-based Streaming Video”
