Unless you work daily in the streaming business, it’s sometimes hard to get into the nuances of technologies, and what the impact is for your long term strategy. HLS and HDS are both HTTP based streaming protocols, and sound very similar, but are fundamentally very different.
HLS stands for HTTP Live Streaming and is Apple’s proprietary streaming format based on MPEG2-TS. It’s popular since it provides the only way to deliver advanced streaming to iOS devices. It often mistakenly gets defined as HTML5 streaming, but is not part of HTML5.
