    When it comes to streaming live video at the professional level, creating a pleasant experience for your viewers is of utmost importance. Keeping latency low is one thing that contributes to the viewer’s experience since it allows viewers to watch the events on the screen in close to real-time. Latency is the amount of time between when an image is captured, and when the frame is displayed on your screen. With live content, low latency streaming is a must.

    Different industries will benefit more than others from low latency live streaming, but it is generally a great practice in professional broadcasting. Low latency video streaming is essential for professional broadcasting. 

    In this post, we will explain what low latency streaming is and take a look at the features you should look for when choosing a low latency streaming platform. We will wrap things up by mentioning a few great encoders for low latency streaming.

    Let’s get started.

    What is Low Latency Streaming?

    Live Streaming Without Delay
    Live streaming without delay helps make your streams more viewer-friendly.

    In live streaming, video latency is the delay between when a video frame is captured and when that frame is displayed to the viewer. For example, if you’re watching a live sporting event, the latency is the time between a play happening in real life and when the play appears on your screen. You want the stream delay to be so short, that it isn’t noticeable.

    Latency takes place in a broadcast because processing and sending live video takes time. It doesn’t take much time, of course. Nonetheless, each step in the process results in a tiny delay, resulting from the time required for:

    • Cameras to process images
    • Encoders to transcode
    • Transmission to viewers
    • Buffering, and
    • Viewing devices to decode and display the final video.

    For streaming video, high latency and lagging can ruin a broadcast in many different ways. First, it can contribute to a sense of lagging that can ruin the viewer’s experience. Low latency streaming is especially important for certain types of content like sports.

    Viewers want to be seeing things as they are happening; no one wants to see a tweet on Twitter that someone scored a goal before it happens on their screen. 

    Minimizing latency helps relay the content you’re broadcasting to your viewers in more of a “real-time” fashion. It helps keep them connected and engaged since it’s the closest thing to attending your event in real life. Avoiding a live stream delay keeps your viewers engaged in real-time. 

    According to Encoding.com, most live streams have latency in the 30-120 second range—sometimes more. In fact, there are two parts to latency: startup time and the lag between the event taking place and the live stream showing it on a viewer’s screen. Both are important to the viewer’s experience. Unfortunately, reducing one latency component can increase the other, in some cases. That is why it is important to understand how to effectively stream with less delay. 

    The Value of Low Latency Streaming Services

    We’ve established that low latency is often the preferred way to stream, but you’re likely wondering why this is the case.

    As far as startup time, studies have shown that longer startups deter viewers and negatively impact their experiences. Online videos with a start-up time exceeding even two seconds have significantly higher streaming video abandonment rates. Each incremental second lag propels another 6% of viewers to jump ship. That is why learning how to stream with no delay, or as little delay as possible, at the start of your video is essential to retaining viewership.

    Low latency during the broadcast itself is critical in a variety of situations. Here are a few scenarios in which low latency streaming media solutions are especially critical:

    1. Sports streaming
    2. Live auctions
    3. Live streams involving chat, real-time feedback, or audience participation
    4. Gaming
    5. Gambling
    6. Dual-screen viewing (which is increasingly common for all sorts of broadcasts)

    Using low latency streaming helps viewers to watch these events unfold in almost real-time, which creates a more lifelike experience. Getting rid of streaming lag is the best way to keep your viewers engaged. 

    How to Choose the Best Solution for Live Streaming Without Delay

    There are very few low latency video streaming platforms on the market today. Each offers a different combination of price, usability, and features.

    Let’s take a look at some of the features that you should look for when choosing a solution to live stream without delay.

    HLS Streaming Protocol Delivery

    HLS streaming
    Make sure your chosen streaming solution uses HLS streaming.

    The best low latency video streaming platforms use the HLS streaming protocol. “HLS” is short for “HTTP Live Streaming” and it was designed by Apple to work with HTML5 video players. Both of these technologies are successors to the ancient Adobe Flash Player technology.

    Most HLS streams start with RTMP ingest which is automatically converted to HLS for delivery by the video platform. This provides a high-quality stream to viewers but can introduce a latency of 30 seconds or more. That is a huge live stream delay.

    The reason that RTMP is still used for video ingestion rather than using HLS for both deliveries and ingest is that HLS on its own has a much higher latency. The RTMP ingest/HLS delivery combo makes it possible to stream on an all-device HTML5 video player while reaping RTMP’s benefit of low latency.

    Paired with the right CDN, this technology can help decrease your latency into the 12-15 second zone. This is a much better live stream delay.

    Less than 15 Seconds of Latency

    As we mentioned, low latency streaming requires a combination of features. Just because a streaming solution has one or two of these features doesn’t mean they have ultra low latency video streaming.

    If it is not published on their website, you’ll want to specifically ask a sales representative for the streaming solution how many seconds of latency their platform has. Under 15 seconds is typically ideal for most types of professional broadcasting, whereas ultra-low latency tends to be as fast as under 1 second. Ultra low latency video streaming should be the goal if you want the best experience for your viewers. 

    A latency of 10 seconds or less is within the range of cable TV and most other professional broadcasts, whereas ultra-low latency tends to be as fast as under 1 second. Dacast, for example, offers HLS delivery with RTMP ingest for low latency streaming. This reduces latency to 15 seconds or less. That is the type of live stream delay you want for a professional broadcast. 

    We’re constantly working to reduce our latency so that our users can produce live streams that are even close to real-time streaming. We’ve recently partnered with Limelight CDN with the launch of our UApp to reduce latency even more. Dacast continues to invest in the best tools so that you don’t have to think about how to reduce stream delay; we will take care of it for you.

    Simple to Set Up and Use

    Find a low latency streaming platform that is easy to navigate.

    If you are new to professional broadcasting, you’re going to want to choose a low latency streaming solution that is easy to use. Unless your role at your company is dedicated to producing live streams, you likely don’t have the time for a steep learning curve. That is why you need a video hosting service that makes learning how to reduce stream delay as easy as possible. 

    Choose a streaming solution that is both simple to use and has a reliable customer support team that is there to help you when you need it.

    It is also a good idea to make sure your streaming solution works seamlessly with professional equipment as well as with the laptop or computer you plan to work with. For example, Dacast simply requires a consumer-grade laptop to run (i5 processor and 8 GB of RAM minimum). You can also use the OBS Studio software encoder with Dacast, which is free to use.

    Compare that to hardware encoders or workstations that typically cost $1,000 and up (some cost $10k+), and you can save substantial amounts of money. This makes it easier than ever to stream professional-grade broadcasts without a massive budget.

    Fits Your Budget

    Live streaming pricing varies widely. Many online video platforms offer cheap introductory pricing but limit professional features to very expensive platforms. 

    For example, a service like IBM Cloud Video restricts features like API access to plans costing over $999 per month.

    As another example, Vimeo restricts 24/7 live streaming, monetization, advanced security features, dedicated support, and video API access to custom plans with a similar very expensive price range. 

    These aren’t cherry-picked examples. Almost every live streaming platform on the market requires a bit of an investment to access more advanced features.

    Dacast offers live streaming starting at just $39 per month and all access to premium features starting at $188 per month billed annually. This includes all the features that are restricted to these other streaming solutions. Dacast offers low latency streaming at a price all businesses can afford. 

    VOD hosting, live streaming, API access, monetization, 24/7 tech support, and all security features are included with every Dacast plan. Dacast offers a full host of professional features that will allow you to produce professional content, and avoid a long live stream delay when you broadcast. 

    Reliable Content Delivery

    Sixty-three percent of live stream viewers last year cited buffering issues as the most serious issue they experience, and that number is an increase from the previous year.

    Lagging and buffering point to a serious issue. The best solution to this problem is to use a robust CDN or Content Delivery Network or a multi-cdn solution

    A CDN is a network of thousands of servers distributed to data centers around the world. These services help deliver content to users fast. They do this by automatically duplicating data and using intelligent routing algorithms to find the fastest path to any given viewer.

    That way, no matter where your viewer is located, the stream latency they experience will be as low as possible. 

    This process speeds up delivery, reduces buffering and lagging issues, and further minimizes latency. It also provides a level of redundancy, security, and scalability so that your video can reach any size audience. You don’t want to introduce latency in your streaming when your audience grows; a multi-CDN network can avoid that.

    Not all CDNs are created equal. Some are much smaller and slower than others, and some CDNs don’t support live streaming video at all. Dacast works with Limelight, which is regarded as one of the most reliable CDNs on the market. That means that your livestream delay will be as short as possible for your viewers around the world. 

    Top 3 Solutions for Live Streaming Without Delay

    Now that you have a better understanding of what to look for in a low latency streaming service, let’s take a look at some of the top streaming solutions with integrated low latency live streaming options.

    Wowza is a good choice if you want to enjoy low latency in streaming, and you don’t want to monetize your video content. 

    Encoders for Low Latency Streaming

    As we mentioned, low latency streaming is the culmination of several great features that you’ll find on your video streaming solution. However, you’ll also need some support from some external tools. In order to learn how to reduce stream delay, you need to know what additional tools to use beyond your video hosting platform.

    One of the most important tools for live streaming is a video encoder

    A great free encoder to start with is OBS Studio. It’s compatible with Windows and Mac and includes a wide range of mixing and production tools. Plus, it supports the wide variety of plugins, scripts, and custom themes that are available for OBS. 

    As you become more experienced, you may want to invest in a paid encoding tool. We recommend exploring different hardware and software encoders.
