What’s the difference between streaming and progressive download formats?
Videos in progressive download format (such as Quicktime), must be fully or partially downloaded before they can be watched. Streaming is largely favored over progressive downloads, because it includes many capabilities that progressive downloads don’t (such as its live webcasting capabilities). Who would want to download a large video file to their desktop when they could simply stream it in their web browser? It might help to compare progressive downloading to the VCR, whereas streaming media’s delivery is a lot like broadcast television. Also, because of its direct content-to-consumer delivery, streaming online video is much more difficult to pirate than online video in progressive download format.
