LL-DASH brings live latency in MPEG-DASH down to a few seconds using CMAF chunked transfer encoding (CMAF-CTE): the encoder emits small chunks within a segment and the CDN streams them to the player via HTTP chunked transfer as they are produced, rather than waiting for the whole segment.
It pairs naturally with CMAF, so the same low-latency chunks can underpin both LL-DASH and LL-HLS, simplifying a dual-protocol setup. As with all low-latency streaming, the gains come from shrinking the buffer, which sharpens the tension between latency and resilience and demands careful ABR and infrastructure tuning.
