Low Latency Streaming is a fast way to deliver video content to users without any buffering or delay whatsoever. The viewing experience your films offer is a crucial factor that influences whether or not your viewers will gain attention. A fantastic viewing experience for your visitors should be your top consideration while streaming live videos properly. Keeping your streams’ latency low is one way to create a great live video viewing experience.
You certainly devote a significant amount of money, and creative energy into selecting an ideal setting for your videos and refining the material you intend to record. Keeping your viewers interested and amused is crucial if live streaming is your preferred method. In this blog, we’ll gonna explore some of the key aspects which connect low latency with the live streaming of videos.
What is Low Latency Streaming?
Low-latency video streaming is the traveling of video content from one place to another. In other words, it is the time taken by the video to travel from the camera to the final display in front of the audience. However, the delay time is variable here ranging from 15 seconds to 30 seconds in some particular cases.
Low latency plays a significant role in determining the live streaming latency of a video. It is recommended to have a latency time of less than a minute in case of live video production. In addition to this, it should be kept in mind that streaming video takes time to transfer from the source to the viewer’s device. This time period is the deciding factor for the success of the event for the broadcasters.
Why Low Latency Streaming Doesn’t Even Matter?
From the user’s point of view, high latency creates unnecessary annoyance while streaming any sporting event or something. However, high latency is mostly preferable for the recorded videos to play afterward. In fact, they deliver high picture quality which attracts more audience to the content.
A short delay during the streaming is all you need for subtitling, captioning, and other small requirements. Low-latency streaming works to deliver video content without any buffering whatsoever. With low latency streaming solutions in the market, persons with not-so-strong bandwidth connections are also able to view the content with any hustle.
Most Use Cases of Low Latency Streaming
Low latency streaming works well with different encoders and is preferable to use with lower bandwidth connections. However, here are some of the most used cases of these services –
-
These services are taken into use for security as well as surveillance purposes. It works well with metadata, resulting in split-second decisions.
-
With hybrid workplaces coming into the picture, most employees want to work remotely. For this, relying on the low latency videos to make quick adjustments before going live is a good way to make the most of these services.
-
Recently, most of the games are supporting low latency streaming for quick movements and making real-time interaction as smooth as possible.
-
These services come into play while having a Video Chat. it takes time from both sides (source and viewer) to exchange the video over the platform. However, with an increase in time, it can be very painful for both of them.
Working Process of Low Latency Streaming
Apply Due to its dependability, HLS is the most popular protocol for stream transmission. However, initially, it was very different for real low-latency streaming. As an HTTP-based protocol, HLS broadcasts data in a specified number of chunks before video players can begin to play. If you’re using the standard chunk size for conventional HLS (10 seconds), you’re already running far behind schedule.
Listing Some Of The Frequently Used Low Latency Streaming Protocols
Here are some of the most popular Low Latency Video Streaming Protocols –
RTMP Streaming Protocol
Most broadcasters still prefer this protocol over others for the efficient transmission of high-quality video to the users. However, for most of the front-end operations, its use has become obsolete. In addition to this, RTMP Streaming also supports almost all types of media servers and works well with leading social media platforms. It is not an open-source technology and also does not fits with the latest HTML 5.
WebRTC
It is one of the most popular choices when it comes to finding browser-based applications for event service providers. This is an open-source technology that thus allows the delivery of low latency in a flash-free environment. The major advantage of using this protocol is its 500-millisecond delivery with low latency and end to end in use in particular cases.
SRT
Those who are facing the problem of unreliable networks thus opt for this streaming protocol. SRT is more of a UDP-like protocol that is in use for the transmission of high video quality. However, the delivery can be made to larger distances, it suffers from customization problems.
Reducing Latency Without Compromising With Picture Quality
There are many ways to reduce the latency without actually affecting the quality of the video. The first one is the use of a video transport protocol which works well in delivering the highest video quality at lower latencies over noisy public networks such as the internet. Additionally, choosing ultra-low video latency over the internet involves the prevention of packet loss and error connection on regular basis.
The second method is all about using suitable hardware encoders and decoders in a perfect combination for keeping the latency as low as possible. It works well with lower bandwidth and poor internet connections. It’s critical to carefully analyze the influence of the setup of the various components based on the use case while attempting to minimize latency. Trade-offs should constantly be taken into consideration.
Summing Up
Because low latency streaming has an exchange, you should consider how your video streaming will benefit from being close to real-time. Low latency video streaming is no longer a matter of competitive advantage for any high-interaction, moment live streams, such as webinars, video conferencing, online meetings, virtual events, and virtual schools. Tech firms push the boundaries to address the technology requirements of remote workers and social estrangement. Audiences now anticipate continuous, real-time live streaming.
