reduces learning times by almost 20%• Increase Flexibility and Reach
– Reach students in remote locations – home, other districts, dorms– Students can access lectures at their convenience– Video can now be sent anywhere the computer network reaches
(wireless, internet, etc.) - no longer tethered to coax• Enabler for new applications
– Video compression lets you bring video to anywhere (wireless, mobile, iPOD)

Applications for streaming video
October 2006 Property of VBrick Systems
Lecture Delivery and Recording
Then Now
Teacher gives lecture at fixed time/day
If you can’t make it to class…you are out of luck or must rely on someone else’s notes
If the class is full access to the class is denied
Teachers can stream their lectures live while recording them for future playback
Students can view the lectures live from anywhere on the computer network – student lounge, overflow classroom and their dormitory rooms
October 2006 Property of VBrick Systems
Delivery of stored assets
Then Now
Visit the media specialist to check out a tape - pray that it is there and that you wont be put on the waiting list
Coordinate the borrowing of the VCR/TV cart
Play tape in classroom, hope that the quality is acceptable
Teachers access the video-on-demand server right from their PC and send the video to the classroom TV or digital projector
Students with permissions can view any of the stored assets from anywhere on the computer network – student lounge, overflow classroom and their dormitory rooms
October 2006 Property of VBrick Systems
Cable TV Distribution
Then Now
TV in the classroom connected to a separate coax network
Separate infrastructure to purchase and maintain
Web access, PC applications and TV access completely separate
Teachers use their computer to deliver classroom material while seamlessly integrating live cable TV events or previously saved news clips
Students can view cable channels using a regular computer connected to the IP network in both the classroom and their dormitory rooms
October 2006 Property of VBrick Systems
Special Events
Then Now
Graduation logistics restrict who can attend the festivities
You are provided a limited number of tickets for your friends and family
Still pictures and home made videos are used to recap the event for loved ones who can not attend
Ceremonies are streamed live to overflow rooms and over the Internet to friends and family who could not attend
The graduation can also be recorded and stored for reunions as well as burned to create a DVD for past alumni to be used in fund raising efforts
October 2006 Property of VBrick Systems
Rich Media Presentations
Then Now
Professor prepares a PPT handout for the class lecture
The PPT is made available to students who jot down notes during the lecture
The notes are tucked away for future reference somewhere in your notepad
Teachers give a rich media lecture with their presentation synchronized to the PPT slides while it is streamed live over the IP network and recorded for future reference
Students can view the rich media lectures live from anywhere on the computer network as well as replay the presentation later to review important points
