We announced Smooth Streaming, a high-definition video delivery via web protocols at Digital Hollywood this past week. We are partnering with Akamai in this effort .. and let me tell you: it’s caused my phone to ring off the hook!
The technology uses a chunked encoding methodology to adapt the quality of the video stream to the available bandwidth, making for smoother delivery.
