Live broadcast and delay (latency)

Usually you stream livestream with a latency of 7-45 seconds, which makes it possible to have stable live broadcasts to large numbers of viewers. However, the latency often poses challenges when it comes to interaction, where you need to think about the delay when the participants have to answer polls, write questions in the chat, or other elements that require feedback from the viewers.

Traditional live broadcast takes place via protocol as HLS (HTTP Live Streaming) is delivered with a 30-45 second delay. Low latency streaming is usually defined as around 7 seconds, which is also the delay TV broadcasts usually have. Often, so-called low latency is enough to broadcast live, but when it comes to broadcasts that will engage the audience - it is important to really push the boundaries to create unique and good experiences.

The common types of latency and its definition follows below:

  • Legacy: 20-45 + seconds delay - acceptable for most social media and regular linear TV.
  • Reduced latency: 5-20 seconds - matches traditional cable TV with delay around 5-8 seconds. Common in e-sports.
  • Low latency: 3-7 seconds - good for larger sports and live events, where a second screen should be used for watching.
  • Ultra-low latency: <= 1 second - suitable for very interactive live broadcasts and entertainment where the audience is to be engaged. Also e.g. online casino and betting require this low delay.
  • Real time: <= 500ms - suitable for video conferencing and the like where you need to be able to have two-way communication and conversation, without it getting weird or talking to each other .

What is ultra low latency streaming?

Ultra low latency streaming is about a delay of approx. 1 second and is best suited for very interactive live broadcasts. A really low delay out to the viewers makes ultra low latency streaming perfect for applications where you have to live chat, send out polls and activate the participants in different ways. This type of streaming is also used for live betting and online casinos.

Univid also supports real-time meetings via WebRTC for up to 300 participants, which are regular video meetings without delay that can be used for webinars, panel discussions or the like. But this new setting - ultra low latency, makes it possible to also broadcast live to several thousand participants in high quality in the same session, and at the same time maintain opportunities for smooth and good interaction with the participants.
