iPhone TV: Our broadcast TV recordings in QuickTime H.264 work well on Apple's portable devices. Smooth, 25fps and beautiful. A 30 minute recording is 450MB and needs to be downloaded. You can start playing before it's fully downloaded.
The correct format is manufactured by Podcast Producer, presenting the user with a QuickTime movie that's delivered by HTTP. Serving it from the web server in Mac OS X Leopard Server allows delivery of any part of the recording through HTTP 1.1 byte range requests. Try it.

About the VVR
VVR is an automated attendant to record your television programmes while you're not around. You specify which show should be recorded, and it will not only capture it but also convert it to a much smaller file so it can be accessed from a streaming server (both on and off campus with the appropriate authentication). VVR doesn't send you the entire programme by email, rather it provides a shortcut that is just like a bookmark for TV. This shortcut can show the recorded TV programme right there in compatible email clients, or be opened in a dedicated media player for more functionality.
The power of these shortcuts becomes apparent when you might want to show a colleague just a snippet of the recording. You can create your own shortcut for giving to others, or create an entirely new piece of media drawing your content from many recorded files. In all these cases, you're never dealing with large media files so it's quick and easy to work with television content. Additional VVR tools allow these shortcuts to be used inside web pages, so the original recordings or their subsequent compilations can be used with existing learning content management systems.
