If the latency is high, then there will be no purpose of streaming such events live. So, if you want to stream in real-time to your audience, then you must ensure the latency is as low as possible.
Buffer-free streaming is the basic requirement to ensure good customer experience, hence, low streaming latency is of high importance for any streaming. For the streaming services that are more focused on real-time delivery of the streaming content, low latency is even more significant.
Live auctions, streaming, gaming, live stream with chat, and live shopping are some of the top examples where low latency is a must-have criteria to deliver the streaming content on time. But, even for VOD streaming, it is recommended to ensure low latency streaming to offer lag-free quality streaming to the viewers.
Better User Engagement
User engagement plays an important role for video streaming, especially live streaming. If the video content delivery is delayed, then it may hamper real-time user engagement.

Ultra-low Video Latency
As the name suggests, ultra-low video latency refers to the lowest latency for video streaming and is highly sought-after for nearly real-time video streaming. WebRTC (Web Real-time Communication) is the proper protocol for such real-time video streaming latency including the cases of online meetings, virtual town hall meetings, and other real-time two-way communications taking place over the internet.
Reduced Video Latency
Reduced video latency refers to the video streaming latency of 20-5 seconds. The RTMP (Real Time Messaging Protocol) will help you achieve this reduced video latency. By using HLS (HTTP Live Streaming) or DASH (Dynamic Adaptive Streaming over HTTP) protocols, you can reduce the latency even further.
Standard Video Latency
Standard video latency implies the video latency of +20 seconds. If real-time video streaming is not of your utmost priority, then this can be your preferred video streaming latency. standard HLS (HTTP Live Streaming) or DASH (Dynamic Adaptive Streaming over HTTP) protocol comes into play here.
Also, this video latency is suitable to deliver HD or 4K video quality on a very large scale. So, if live audience interaction is not your concern or for VOD streaming, this option is suitable for you.
Most types of professional broadcasting require a delay of about 15 seconds, whereas ultra-low latency can be as low as 1 second. Low latency is expected for any video streaming be it live streaming or VOD streaming and based on other factors such as audience interaction, real-time experience, streaming protocols etc., you need to decide on how low is good for your video streaming latency.
