How DASH Will Work


Author's Note

Before this article, I knew very little about streaming video standards. Now, I understand the problem with RTSP, particularly regarding wasted bandwidth. Since DASH is a framework for consuming existing video formats, it doesn't disrupt video production itself. That also means that proprietary formats like Flash could be delivered with the advantage of DASH efficiency. As someone who loves to use YouTube on my smartphone, I look forward to the improved experience and reduced bandwidth that the DASH standard could deliver. I also hope that security mechanisms that limit HTTP requests from the same client can adapt to receiving repeated requests for video segments. I'm interested to see how streaming services will handle that while resisting denial of service attacks.
