improved caching performance as the media player is walking through a larger file in a sequence rather than downloading each segment from different location.

HTTP byte range requests allow to specify segments as byte range of a larger URL and consolidate segments into single large file.

In 2016 Apple added byte-range addressing for fragmented MP4 files. References to the segmented files are contained in. Originally HLS used H.264 as video codec encapsulated by MPEG-2 TS chunks.

It is natively supported on OSX, iOS, Android 4.1+ and Windows 10. HLS is media streaming protocol developed by Apple for iOS, Apple TV and OS X that over time has gained support on number of other platforms due to its popularity. And they are both supported in Telestream Cloud. HLS & MPEG-DASHĪpple HLS (HTTP Live Streaming) and MPEG-DASH (Dynamic Adaptive Streaming over HTTP) are currently two most common ABR streaming technologies supported by vast majority of devices. This adaptive behavior is what ensures consistent playback regardless of connection speed or device. Players may also choose variants with different frame sizes or frame rates to optimize the visual experience for the device. While the segment is played, the connection speed is monitored, and the player may opt to switch variants, either increasing or decreasing the video bit rate based upon the connection speed. The video player requests and downloads a segment from a variant. The player is provided with a package manifest file outlining which variants are available and the location of the segments for each variant. Each content package includes multiple variants, and each variant may include many segments.

How it works?ĭuring playback, video and audio are delivered via HTTP in small segments, typically between 3 and 10 seconds in length. The player will adaptively switch between low bit rates and high bit rates, depending upon the connectivity of the device. ABR players switch between variants depending upon the device and available bandwidth, to ensure consistent high-quality playback.įor example, a single ABR package might include six variants, each encoded at progressively higher bit rates.

These variants are combined into a single package that represents the original content.

Adaptive Bitrate (ABR) streaming is a delivery technology designed to provide consistent, high-quality viewing in situations where bandwidth may fluctuate, and where viewers may be on a wide range of devices.ĪBR streaming addresses these issues by encoding content into multiple variants, each potentially a different bit rate, frame size and/or frame rate.
