You want to deliver video to the iPad?
Since the iPad (to be launched this Saturday 3) does not support Adobe Flash, there are two choices. You will need either build a native iPad/Phone application or, easier, build an HTML5-friendly video site.
Either way, you will need to re-encode existing video assets to support H.264 streaming and Apple’s multi-bit rate streaming technology.
Using this technology, the stream adapts to network conditions, scaling up and down based on the amount of bandwidth available.
Encoding videos in the H.264 format should be into at least three different bit rates.
Since iPad videos are streamed via HTTP, they can be delivered from any commodity web server, without needing a specialized streaming server. Apple’s HTTP-based adaptive bit-rate streaming technology allows it.
