Going Live: How Does Live Streaming Work

Are you interested in live streaming? From people live streaming on various social media platforms to live sports broadcasts and more, live streaming has evolved significantly over recent years. This is a fun and exciting way to connect with others across the globe, but how does live streaming work? It’s easy to get caught up in the fun and excitement of live streaming and to forget about the technical side of things.

Live streaming is a technical process that has revolutionized many industries. While you don’t need much knowledge to start a live stream, it’s important to understand how live streaming works to ensure you can create high-quality content and deal with any technical difficulties promptly.

What Is Live Streaming Technology?

Video files are usually huge, making transmitting them to end-users in their original form difficult. This is where live streaming technology comes in. In real-time, specific devices, software, and technology transmit the video to end-users.

It differs from other media delivery types in that you don’t need to download or watch pre-recorded videos. You can view the content as it’s happening, an experience that traditional media delivery cannot offer.

How Does Live Video Streaming Work?

The entire live-streaming process consists of the following:

1. Video capture
2. Compression
3. Encoding
4. Segmentation
5. Content delivery network (CDN) distribution
6. CDN caching
7. Video playback
8. Decoding
9. Let’s look at these processes in a little more detail:

1. Video Capture

First things first, you need a video. Your video camera captures visual information and displays it as digital data. Encoding and compression, the second step of the process, are used to ensure your video data isn’t redundant.

2. Compression

When you first capture your video data, it has a lot of redundant information. By compressing the video, you’ll be able to remove these redundancies. Furthermore, the raw video data you captured might not have the ideal video bitrate and frame size for live streaming. Compressing helps to correct this as well.

3. Encoding

Video encoding consists of converting the compressed video footage format. Firstly, you have to encode the footage using a codec. Next, you can choose the ideal encoding standard for your video. A few common ones are AV1, H.264, H.265, and VP9. Each format is suitable for different uses; therefore, you must choose the appropriate one based on the codecs used for your content.

4. Segmentation

Segmentation is a vital part of the process as it divides your video data into smaller segments, which enables it to be sent. Each segment will be converted into further parts of different resolutions (HD, 4K, 720p, 1080p, etc.), and the parts with the same resolution will be combined, forming a video stream. Therefore, segmentation results in the creation of multiple video streams.

Adaptive Bitrate Streaming (ABR) is currently used by most live streaming software, enabling you to adjust the bitrate by the end user’s bandwidth. As a result, wider audiences, including those with lower bandwidths, can enjoy the live stream without worrying about it constantly buffering.

5. Content Delivery Network (CDN) Distribution

Firstly, you need to know what a CDN is. CDNs are a group of servers located worldwide that enable people to stream a video in their location. Therefore, when someone plays your live stream, they’ll request it from the server that is closest to them.

The main benefit of this is that it significantly reduces transition time, which reduces latency. This way, the viewer will enjoy a higher quality live stream.

6. CDN Caching

CDN caching, similar to CDN distribution, is a way to improve the live stream quality and reduce the load placed on the origin server. The video content is stored and delivered through a CDN during this process.

Therefore, when a viewer requests the live stream, the CDN will retrieve the content from the origin server and cache it to the server closest to it.

7.  Video Playback

When a viewer requests access to the live stream, their device will receive the video segments spoken about in step four. The end-users smartphone, laptop, or PC will then reassemble these segments and play them in real-time.

8. Decoding

The CDN must decode your live video when the viewer first accesses it. This is because the end-user cannot watch an encrypted video file. Thus, the decoder will generate a decoded and decompressed file so the end-user can enjoy your content.

How to Start Streaming

Now that you know how the live streaming process works, you probably want to start creating your live stream. Fortunately, this isn’t a complicated process; you don’t need a flashy and complex setup to start.

Follow these steps, and you’ll be good to go:

1.    Choose a Live Streaming Platform

Firstly, you need to choose a live-streaming platform. While this isn’t complicated, it requires careful thought and consideration. The platform you choose needs to align with the purpose and goals of your live stream. Therefore, you should also consider the features the platform offers.

2.    Get the Necessary Tools and Equipment for Your Live Stream

Next, you need to finalize your streaming setup. You’re ready to start streaming once you have a platform and the necessary tools and equipment!

The tools and equipment you need include:

• A camera
• A high-quality microphone
• A steady internet connection with a decent upload bandwidth

You could also consider investing in lighting, an audio blender, and a green screen. This depends on the purpose of your live stream.

What Are the Benefits of Live Streaming?

Live streaming has numerous benefits, whether you’re a content creator or a business owner.

1. You Can Reach a Global Audience

If you’re hosting an online, live-stream event, you can invite as many people as you like. Furthermore, you’d be able to invite people from all across the world. Therefore, live streaming allows you to interact with others like no other platform or source.

You can share a functional and operational video streaming link with as many people as you like as long as you have a functional and operational video streaming link. People might also be more willing to attend your event as they can do so from the comfort of their own homes.

2. Live Streaming Is Inexpensive

You can choose between using a paid or free live-streaming platform. While paid services might have additional features, free streaming software has everything you need. Therefore, this is an avoidable cost.

Then, the only other cost you would have to worry about is the initial investment in equipment, such as your camera, lighting, microphone, etc.

3. It Is Easy to Use and Set Up

You don’t need any technical knowledge to start a live stream. All you have to do is determine what type of audience you’re trying to attract and decide on the streaming or social media platform/s you want to use.

Live streaming is accessible to everyone. As long as you have a stable internet connection and know which streaming platform you will use, you can get started as soon as possible!

What Are the Potential Risks of Live Streaming?

While live streaming is beneficial for many reasons, it also has a few drawbacks. Modern technology has revolutionized the world as we know it; however, it has also exposed us to various dangers and risks you need to be aware of.

By familiarizing yourself with these potential risks, you can take appropriate measures to address and mitigate them:

1. You Can’t Control Who Views Your Content

You can’t moderate live content. This means anyone can watch live content, even minors. Therefore, parents need to take the necessary measures to ensure their children are not watching inappropriate material on live streamers.

2. Cyber Bullying and Online Harassment

Live streamers often succumb to cyberbullying, online harassment, and negative criticism. Hence, if you’re a live streamer, you must be prepared for this negativity and find healthy ways to cope with negative criticism. Developing a thick skin is vital if you’re going to start streaming.

3. You Cannot Delete Anything You Say or Do

Traditional media delivery has the upper hand when it comes to this. When working with pre-recorded content, you can edit it before publishing it for the world to see. This isn’t possible with live streaming.

When live streaming, you must always be conscious about what you’re saying and doing. Keep in mind that viewers are free to record and share your content. Therefore, there could be a digital footprint of you doing something you regret, which could be used against you.

Live Streaming Uses

Live streaming has gained great popularity over the years because of how versatile it is. It is used across many industries for a wide range of purposes. A few of the most popular uses of live streaming solutions are:

• Webinars
• Virtual events
• Video game streams
• Live broadcasting – news, sports, music concerts, etc.
