ABR (Adaptive Bitrate)

What is it?

ABR is the viewer-side companion of transcoding: the player on the viewer's device automatically switches between the available quality versions, moment by moment, based on how good their internet is right now. The viewer never touches a setting — the video just keeps playing.

Practical example

Someone is watching a live show on their phone at home in HD. They walk out the door and switch to mobile data; the picture quietly drops to a softer quality for a minute, then sharpens back up when they reach an area with strong signal. They never saw a buffering wheel — that invisible smoothness is ABR doing its job.

Key things to know (non-technical)

• The goal is simple: never stop the video. Lower quality is always better than freezing.
• It only works if transcoding produced multiple qualities — ABR is the "switcher," transcoding makes the options.
• Viewers can usually still force a fixed quality manually ("Auto" vs "720p"), but Auto = ABR.
• Smooth ABR is one of the biggest hidden drivers of watch time: people leave frozen streams, not slightly soft ones.

In Tupic Live

ABR in Tupic Live's player means viewers on Dubai fiber and viewers on patchy mobile networks both stay watching — directly protecting watch time and creator revenue.
