I created this short video to illustrate how streaming is more efficient than delivering via progressive download. For illustrating the efficiencies of streaming, I used a file streamed via RTMP, but you can get the same benefit via chunk-based HTTP based technologies like HTTP Live Streaming (HLS), Smooth Streaming, HTTP Dynamic Streaming (HDS), or DASH, when it becomes available. I should note that there is currently no HTML5 compatible scheme for delivering via streaming; it’s all progressive download.
I captured the video at 720p so it’s best viewed at that resolution. Enjoy.
