Low Latency

Low latency is a current evolving method that touches on how content is delivered over the Internet. It is well known for its delivery of live video and audio with minimal or defined latency towards its viewers. This working group specifically focuses on the delivery of low latency video over the Internet.

Problem statement
‘Low latency’ is defined and used as a generic term, yet differentiates in Low-Latency (LL), Ultra-Low-Latency (ULL) and Real-time Streaming (RTS) which at their core are different in technologies, protocols and specifications and have different latencies they can achieve. A problem on its own, besides the fact that there are no clear definitions of ‘latency’ in relation to LL, ULL and RTS, how it is or can be used, no clear measurements, no clear overview of all technologies, protocols, use cases, etc. In general a clear overview with clear definitions has not yet been defined in relation to the delivery of LL, ULL and RTS over the Internet.

To create an overview of, and clarity about the availability, possibilities, and specifications of the most common and upcoming Low-Latency (LL), Ultra-Low-Latency (ULL) and Real-time Streaming (RTS) delivery technologies available in the market today, that can be used for one-to-many delivery scenarios, in order to create consensus and normalization about the language, definitions and specifications used in the market today and in the future.
