How Does Live Streaming Work?

Live streaming represents a powerful tool for audience engagement and content delivery. But have you ever wondered how that real-time video makes its way from your camera to viewers’ screens?

If yes, then your questions are going to be answered here.

And before we delve into the technical workflow, why not first have a look at the different types of live streaming setups? This will help you align your streaming goals with the setup required. 

So, here are the most common streaming setups that you should be aware of:

Webcam Streaming: This is the best option for quick updates, interviews, or webinars. As it offers a low barrier to entry, it is ideal for businesses on a budget or those who are new to live streaming.

Mobile Streaming: This is the most convenient, portable, and on-the-go solution for live streaming. Many platforms provide built-in mobile streaming functionalities, allowing you to broadcast from events, locations, or behind-the-scenes glimpses.  

Encoder Streaming: This setup is a bit costly, but at the same time, it offers the most control and flexibility. This is ideal for businesses aiming for a premium viewing experience or large-scale productions. A dedicated live streaming encoder requires multi-camera setups, high-quality audio, and complex graphics integrations.  

Now, let’s understand the basic workflow of live streaming, which comprises five key steps:

Basic Workflow of Live Streaming

1. Compression and Encoding:

The journey begins with capturing raw video data, be it from a phone camera, a professional setup, or even a gaming console. However, this unprocessed footage is massive! To ensure smooth delivery over the internet, it undergoes compression and encoding. 

Compression removes redundant data (like similar frames) while encoding converts it into a format suitable for web transmission.  

2. Segmentation:

The next step is chopping it up for delivery. After the first step, the compressed video stream is sliced into smaller, manageable chunks. This allows viewers to start watching immediately without waiting for the entire video to download. 

3. Content Delivery Network (CDN) Distribution:

Now, to make live streaming fast, the segmented packets need to reach viewers across the globe with minimal delay. That’s where the Content Delivery Network (CDN) comes into the picture.

It is a geographically distributed network of servers strategically positioned around the world. The video segments are sent to these servers, which then act as local outposts, reducing latency.

4. CDN Caching:

To further optimize delivery, CDNs employ caching. You can think of it like your web browser storing frequently visited websites for faster loading. Popular video segments are stored on servers closer to viewers. This reduces travel time for the data, resulting in faster playback and less buffering (those annoying pauses).

5. Decoding and Video Playback:

Finally, when viewers hit play, their devices (phones, computers, tablets) connect to the CDN, requesting the video segments. The closest CDN server dispatches the pre-segmented chunks, one by one. 

Live streaming player on the viewer’s device then decodes and assembles these chunks back into a smooth, flowing video stream – the live content you see unfolding in real time!

What is the Technical Setup You Need For Live Streaming?

Creating the ideal live streaming setup looks different for each broadcaster. Because live streaming is used for many different objectives in so many industries, there are numerous factors to consider when designing the optimal streaming setup for your company.
