If you’re unfamiliar, adaptive bitrate streaming (ABR) is the practice of delivering media data that adapts to the quality of an end user’s internet connection. Another of the most significant ways they are similar, however, is their usefulness in adaptive bitrate streaming. DASH is not particularly complicated because they both use HTTP. Unfortunately, iOS and Apple TVs don’t support DASH, but products from Android, Samsung, Panasonic, Philips, and Sony products, do, along with Chrome, Safari (with an HTML5 video player because it’s an Apple property), and Firefox browsers.Īs we’ve mentioned, the argument of HLS vs. It delivers video and audio data in chunks less than 10 seconds long (DASH is known to use shorter chunks than HLS, around two to four seconds) to optimize accuracy, avoiding skips and buffering during playback.ĭASH is also open source, meaning it’s not a proprietary protocol and anyone can access and modify it as they see fit. However, Apple’s prominence in the tech world has launched HLS to near-ubiquity, so DASH isn’t quite the unifying protocol MPEG intended for it to be - but it’s still a viable alternative that has its place in the market.ĭASH is also HTTP-based, so it works similarly to HLS from a technical standpoint. MPEG, the Moving Pictures Expert Group, created DASH - Dynamic Adaptive Streaming over HTTP - specifically to be an industry-standard protocol back when Apple HLS was competing with many others.

Almost every kind of app and device supports HLS streaming, including Microsoft, Android, Windows, Smart TVs, and Linux products, not just Apple. Apple initially recommended broadcasters use 10-second segments but reduced this number to six after 2016 to minimize latency.Īnd more. HLS works by segmenting video into fragments instead of delivering a continuous stream. Apple originally developed HLS to enable iPhone users to watch live streams but it is now one of the most common and widely supported protocols for transporting video data from media servers to a multitude of devices.īecause HLS uses HTTP, any typical Content Delivery Network ( CDN) will suffice for distributing content instead of requiring specialized infrastructure.
HLS stands for HTTP Live Streaming, HTTP being the same language that composes most of the internet.
