Traditional HLS protocol

HLS becomes the most popular protocol

HLS is HTTP-based, it uses a web server to transmit content. This means that businesses do not need to have a special infrastructure, just have a web server or use a CDN.

Also, since HLS is HTTP-based, it is also less likely to be blocked by the Firewall. With the traditional HLS protocol, the video will be divided into small segments for transmission over the Internet depending on the internet speed in the viewer’s place.

The disadvantage of traditional HLS is high latency.

The traditional HLS protocol can be easily scaled for delivery by conventional Web servers on a global content delivery network (CDN). By sharing the workload across a network of HTTP servers, a CDN can accommodate a spike in viral viewership and a larger-than-expected live audience. CDNs also help improve the viewer experience by caching audio and video segments.

HLS transmits Video and Audio data from the Media Server to the viewer’s screen. Whether you are watching Live Streaming (Live Streaming) via an app on your phone or watching content on demand (Video On Demand) on your smart TV, Now the Live Streaming HLS feature will be selected to respond. Especially when your Video audience uses Apple devices.

Although HLS provides a reliable method of video streaming, its high latency creates many obstacles for video streamers or distributors.

Low Latency HLS Protocol (LL-HLS)

With HLS, content distributors can ensure a smooth live streaming video experience across a wide range of devices, while relying on a content delivery network (CDN) to deliver Videos to global viewers. Video size and quality often depended on CDN technology, but that all changed when Apple released LL-HLS.

Traditional HLS has been replaced by Low-latency HLS with a delay of only 1 to 2 seconds

One of the main advantages of using LL-HLS is backwards compatibility with older HLS players. Players that do not support LL-HLS can revert to traditional HLS and still operate with higher latency. Since the LL-HLS protocol requires players to load unfinished media segments instead of waiting until they are fully available, changes in the specification make it difficult for most players to adapt in time.

Now, LL-HLS is widely supported on most platforms with relatively newer player versions. Here are some popular players from different platforms that support LL-HLS:

  • AVPlayer (iOS)

  • Exoplayer (Android)

  • THEOPlayer

  • JWPlayer

  • HLS.js

  • VideoJS

  • AgnoPlay

LL-HLS is currently the widely used protocol for multimedia streaming, which is a safe choice for the majority of broadcasts. Anyone Live Streaming to connected devices should at least consider it - especially when it comes to living events and sports, these services demand video quality and low latency above all.

LL-HLS has a low latency of only 1~2 seconds. This makes LL-HLS suitable for online interactive Live Streaming services, online games, sports events, and live TV events,…
