What is Ultra Low Latency and Why Does It Matter?

In today’s fast-paced digital world, speed is everything. Whether you’re streaming live sports, placing bets on the big game, monitoring traffic cameras, or coordinating emergency response efforts, even the slightest delay can have a significant impact on user experience and business outcomes. This is where our ultra low latency video streaming comes into play.

Ultra Low Latency has become such an important aspect of live streaming that even giant consumer streaming platforms like Twitch have introduced low latency mode to their offering allowing for their streamers to reduce the delay in their video transmission for better interactivity.

In this blog post, we’ll explore what it is, why it matters, and how we at Red5 lead the way in delivering lightning-fast, real-time experiences across a wide range of industries.

What is Ultra Low Latency?

Ultra low latency streaming refers to the minimal delay between the transmission of data from a source and its reception by the intended recipient. In other words, it’s the time it takes for information to travel from point A to point B. When we talk about it, we’re typically referring to delays measured in milliseconds or even microseconds.

To put this into perspective, let’s consider a real-world example. Imagine you’re watching a live world cup soccer (fútbol) game online. When a goal is scored you expect to see it happen in real-time, without any noticeable delay. Let’s say you have a friend at the game and you are texting back and forth. If there’s a significant lag between the action on the field and what you see on your screen, it can be frustrating when your friend sends you an update before you see it live. This is where our ultra low latency video streaming comes into play, ensuring that you can experience the thrill of live sports as if you were there in person.

One potential point of confusion is that many in the video streaming business consider “ultra low latency” to be a delay in video transmission between 1 and 4 seconds. The above use case would probably still work with this level of delay in the live stream. However for us, 1 to 4 seconds would be considered extremely high latency, and many in the industry would call Red5 Pro’s WebRTC sub-second latency delivery (typically less than 250ms) “real-time latency”. For this sake of keeping things simple, in this post we are using the terms interchangeably.

Why Does Ultra Low Latency Streaming Matter?

It is crucial for a wide range of applications and industries. Here are just a few examples:

1. Live Sports Streaming: As mentioned earlier, live streaming with high latency video is an issue for delivering a seamless and engaging live sports viewing experience. Fans expect to see the action unfold in real-time, without any delays or interruptions. As new emerging experiences that include highly interactive live streams emerge, combining aspects from video conferencing such as watch parties, the latency of the live video video becomes even more important.

2. Live Sports Betting: In the world of sports betting, low latency live video is critical for ensuring that bets are placed and processed in real-time, based on the most up-to-date information. Even a slight delay can result in missed opportunities or unfair advantages.

3. Traffic Monitoring: Our ultra low latency live streaming is essential for enabling real-time traffic monitoring and management. By processing and analyzing data from traffic cameras and sensors with minimal delay, authorities can quickly identify and respond to accidents, congestion, and other issues.

4. Live Drone Footage: As drones become increasingly popular for a variety of applications, from aerial photography to search and rescue operations, ultra low latency video streaming is crucial for enabling real-time footage and remote control. Any delay in the transmission of video, data, or control signals can be dangerous or even catastrophic.

5. Surveillance and Security: Live streaming with sub-second latency is essential for enabling real-time monitoring and response in surveillance and security applications. Whether it’s detecting and responding to a security breach or monitoring a sensitive area for suspicious activity, our ultra low latency capabilities ensure that personnel can react quickly and effectively.

6. Emergency Response: In emergency situations, every second counts. Our ultra low latency streaming solution is cucial for enabling real-time communication and coordination between first responders, dispatchers, and other personnel. By minimizing delays in the transmission of critical information, we can help save lives and minimize damage. We continue to see emerging applications that combine comms over video conferencing with the near real-time live stream become commonplace.

How We at Red5 Deliver Ultra Low Latency

At Red5 (www.red5.net), we are a leading provider of ultra low latency solutions for real-time video streaming, gaming, and data delivery. Our cutting-edge technology is designed to minimize latency and ensure seamless, real-time experiences for our users across a wide range of industries, from live sports and betting to traffic monitoring and emergency response.

One of the key components of our solution is our custom-built media server. Unlike traditional media servers, which can introduce significant delays due to buffering and processing, our server software is optimized for speed and efficiency. By leveraging advanced techniques like WebRTC (Web Real-Time Communication) and a wide variety of other protocols (Zixi, SRT, RTSP, etc), we are able to achieve ultra low latency video streaming with unparalleled speed and reliability.

Our Experience Delivery Network (XDN) architecture is designed to deliver real-time live video at scale, leveraging a network of origin and edge compute nodes that optimize streaming performance across diverse geographic locations. In this architecture, the origin server acts as the central hub, receiving initial streams from broadcasters. These streams are then intelligently distributed to edge nodes, which are strategically located closer to end-users to minimize latency. As viewers connect to watch a live event, they are automatically routed to the nearest edge node, ensuring that they receive the stream with the least possible delay. This method not only significantly reduces the latency that can hinder real-time interactions but also scales efficiently by distributing the load across multiple nodes. The result is a robust, high-performance streaming solution capable of handling large volumes of simultaneous viewers with near-zero latency, maintaining the quality and immediacy of live video content delivery.

Another important aspect of the XDN architecture is the flexibility of where it can be deployed, whether it be in the cloud on the customer’s tenant, on-prem, or on edge networks like AWS’s Wavelength. By our customers being able to strategically place origin and edge nodes in key locations around the world, they are able to minimize the physical distance between our users and the content they’re accessing, resulting in even lower network latency and faster response times.

Soon with the launch of Red5 Cloud, customers will be able to deploy Red5’s XDN with a click of a button reducing the overhead and complexity of maintaining the software on their own infrastructure. If you are interested in reducing latency and don’t want to manage Red5 Pro on your own system, then this is the solution for you. Sign up here to get early access.

In addition to our technical infrastructure (whether deployed on your servers or via Red5 Cloud), we also offer a range of tools and services to help businesses and developers integrate ultra low latency video streaming into their applications. Our software development kits (SDKs) and APIs make it easy to build sub-second latency mobile streaming and data delivery solutions, while our managed hosting and support services provide the expertise and resources needed to ensure optimal performance and reliability.
