what is live streaming how live streaming works

Live streaming – the word itself needs no new introduction. We all have seen and enjoyed a live stream at least once in our life. Be it the live online music concert of our favorite pop star, or the live online interview of our favorite actor. Even online sports live streaming and esports matches. All of them come under the umbrella of live streaming

In recent years, live streaming has grown so popular that it already crossed a market size of US$ 37.35 billion in 2021. And by 2029, it is expected to reach a market size of US$ 252.78 billion, growing at a CAGR of 27% from 2022 to 2029. 

Now you must be wondering if live streaming is that simple, why are you even reading this blog? Well, a live stream looks simple to the viewers, but technically it is not that simple! Live streamers need to be fully aware of the technical process involved in live streaming, otherwise, they end up committing live streaming mistakes

So, if you are a new live streamer looking to understand the technical details of live streaming, then you are on the right page! In this blog, we will tell you everything you need to know about live streaming, its technicalities, how live streaming works, and more! So, keep reading!

So, What is Live Streaming?           

When the streamer streams the video live in real-time, such streams are called live streams. In short, in the case of live streams, the feed gets telecasted to viewers at that very moment. 

So, how is it different from normal video streaming? In the case of normal or on-demand video streaming, a recorded video is uploaded and encoded to the server, and the same encoded file gets decoded and streamed whenever a viewer requests to play it. 

But in live streaming, there is no recorded file. Whatever video feed is generated by the live streaming setup, that very feed is streamed to the viewers after encoding. This process is very quick and takes place at a lightning pace. Let’s understand the process in detail. 

How Does Live Streaming Work?  

Live streaming starts from the moment the live streamer switches on her camera. The raw video feed collected from the camera passes through the following steps before being delivered to the viewers:

  1. Compressing the video
  2. Encoding and Transcoding
  3. Video Segmentation
  4. Distribution through CDN
  5. CDN caching
  6. Decoding
  7. Playing The Video on end user’s device 

Let’s take you through all these steps one by one. 

how does live streaming work

Video Compression

When the raw video feed is generated, it has multiple redundancies. Also, its frame size and video bitrate may not be ideal for live streaming. So, the raw video is compressed so that the redundancies can be removed and the ideal video bitrate can be achieved. 

Encoding and Transcoding

It’s now time to convert the format of the compressed video footage. First, the raw video is encoded using a codec, which is further packed into a container or format. This process is called encoding. 

Now, there are many video encoding formats available nowadays, and each one of them has different applications. You need to choose a format that supports the codecs used to pack your content. Some of the top video encoding formats that are used frequently are:

  • MPEG-4 Part 14 or MPEG-4 AVC
  • AVI
  • H.264 & H.265
  • FLV

Video Segmentation

Nowadays, most live streaming software uses Adaptive Bitrate Streaming (ABR). It makes your live stream flexible enough so that it can adjust its bitrate according to the bandwidth of the end user. Hence, even remote users with lower bandwidths can enjoy a buffer-free live stream. 

For this purpose, the video is first segmented into smaller chunks of video, and then each chunk is converted into multiple chunks of different video resolutions like 4K, 1080p, HD, 720p, etc. Then, chunks of similar resolution are combined together to form a video stream. In this way, multiple video streams are formed. 

Distribution through CDN

Once the video feed is ready to be telecasted, it is first sent to a CDN server for distribution. CDNs or Content Delivery Networks are a group of servers spread across the globe. When a viewer plays the live stream, the player requests the live feed from the nearest server located to the viewer. In this way, transition time is reduced, hence improving the quality of the stream by reducing the latency. 

CDN Caching

The process by which CDN caches the live feed and transmits it to the viewers is called CDN caching. When CDN receives the request from the viewer, the CDN server located nearest to the viewer gets activated and starts to catch the live feed (in the form of video segments as discussed above). Then, this cached feed is sent to the requested viewer. 

Decoding

When the viewer’s player receives the feed from the CDN, it needs to decode it first, as it is in the encrypted form which cannot be played. So, the video feed is decoded by the decoder (which is a part of the codec), and a decoded and decompressed video file is generated. 

Playing The Video on end-user’s device

This decoded video file gets played on the end user’s device. Hence, the entire live streaming process actually involves 7 highly complicated technical steps which get complicated within seconds!

How to Start Live Streaming 

Now that you are technically aware of the live streaming process, you must be wondering how you can start your own live stream. Well, starting a live stream is not at all difficult, and a very minimal setup is needed for it. Let’s take a look at the setup you would need to start your own live streaming.
