More on streaming media

The multicast part of the streaming media design is to unicast from Mac Minis (connecting directly to video sources) to QTSS and then multicast out to campus. The main reason was because, originally, the Minis will not be the main streaming distribution point with the XServ (running QTSS); so, there was concern of creating network bottleneck. This has been changed since the Minis will be moved to distribution point; so, the need of unicast to XServ/QTSS is not there anymore. The direct multicast from the Minis will actually provide better performance and reduce the possibility of another point of failure (QTSS).

However, streaming from out of the distribution point should still be relayed by QTSS.

iTunes U is beyond MP3 files...

In general, Podcasting is to create audio files in mp3 or AAC format and video files in MPEG4/H.264 format to be distributed through RSS feeds.

The facts:
It is that Podcasting does NOT require iTunes U as the distributing interface.
It is that Podcasting can be done without iTunes U.
It is that iTunes U does NOT produce podcasts.
It is that iTunes U is to publish podcast content.
It is that iTunes U implementation is NOT a standalone application.
It is that iTunes U is to be integrated with the institution's infrastructure.

So, here are the challenges:
iTunes U relies on another 'Front-End' application for user access.
iTunes U requires design on content partitions for management.
iTunes U needs IT supports with the 'common' requirement of iTunes player and Quicktime player.

iTunes U implementation is beyond the Java codes or how to help faculty to create MP3 files.

What I am going to do? I am thinking .. differently!

iPeer started

This is for the Peer Review project that I promised to deliver a pilot for business school in Fall. I like iPeer's Rubric implementation, but it will take some work to implement it for our additional use cases. My goals is NOT to make any change on iPeer's original implementation, but add features to it. It is challenge!

First Day at Denver, CO

First time being Denver. Excited!

Anyway, when I tried to get ready for tomorrow's session, oops, it needs to be able to boot linux from the CD drive. .... I have a Mac Book .. What now?

I am starting downing Parallels and hope it works for tomorrow. Perhaps, I should try VMWare for Mac. Let me think about it!

Oh, by the way, I am at JA-SIG Summer Conference 2007.
