Computer vs. Auto Industry• “If GM(General Motors) had kept up with technology like the
computer industry has, we would all be driving $25 cars that got 1000 miles to the gallon” – Bill Gates at COMDEX
• “If GM had had developed technology like Microsoft, we would all be driving cars with the following characteristics” (GM issues a press release)
• For no reason whatsoever, your car would crash twice a day• The airbag system would ask “Are you sure?” before
activating• Occasionally your car would die on the freeway for no
reason. You’d just calmly accept this, restart your car, and then drive on

Videostreaming and SMIL-aided Approach to Teaching MIS
The purpose of the presentation is
•to describe the technologies (video streaming and SMIL)for teaching MIS
Examples of video streaming and SMIL
MBA MIS class schedule with ppt slides
Case study presentation
Students’ assessment of streaming tech
Hyperlink with AT&T Video Streaming
Streaming Technology
• Several professional journals, including IEEE Transactions on Circuits and Systems for Video Technology
•In the streaming mode, a user plays the video content simultaneously while parts of the content are being received and decoded.•In the download mode, a user downloads the entire video file and plays back the video file.
Business Telecom Term Project using SMIL
SMIL (Synchronized Multimedia Integration Languague)
