2024 Full Guide to Adaptive Bitrate Streaming (ABR)

Jane Zhou updated on Mar 22, 2024 | Home > Glossary and Terms

With the rise of high-speed internet connections and the increasing demand for high-quality videos, adaptive bitrate streaming has become a crucial tool for content delivery. But, most people still feel unfamiliar with this term. Given that, this post from EaseUS comes in handy. Here, we will dive deeper into adaptive bitrate streaming, exploring what ABR is, how it works, its benefits, etc. So, let's get started and unlock the power of adaptive bitrate streaming!

What Is Adaptive Bitrate Streaming?

Adaptive bitrate streaming, also known as ABR, refers to streaming video content with dynamic bitrates that can be adjusted in real time depending on the viewer's situation. In simple terms, the ABR can adjust the quality of a video stream based on the viewer's internet connection speed and device capabilities.

Because in streaming, video is split into smaller segments, and viewers don't need to wait for the full video to load before they can start watching. This allows for a smoother viewing experience by reducing buffering and ensuring viewers receive the best possible video quality without interruptions. To conclude, adaptive bitrate streaming is a way to improve HTTP network flow.

How Does Adaptive Bitrate Streaming Work?

Adaptive bitrate streaming works by encoding a video at multiple quality levels and segmenting it into smaller chunks, which are then delivered to the viewer's device. The video player on the viewer's device monitors the available bandwidth and device capabilities, dynamically adjusting the quality of the video stream in real-time to provide the best possible viewing experience.

Below is a breakdown of how adaptive bitrate streaming works:

Encoding: The video content is encoded at different quality levels, typically ranging from low to high resolution and bitrates. Each quality level is divided into smaller segments, usually a few seconds long, which allows for seamless switching between different quality levels.

Segmentation: The encoded video is segmented into chunks, with each segment containing a portion of the video content. These video chunks are usually stored on a server and delivered to the user's device as needed during playback.

Delivery: The video player on the viewer's device requests video chunks from the server based on the available bandwidth. The player continuously monitors the network conditions and device capabilities and selects the appropriate quality level for each segment to ensure smooth playback.

Adaptation: If the available bandwidth fluctuates during playback, the video player can dynamically switch between different quality levels without interrupting the viewing experience. For example, if the internet connection speed drops, the player will switch to a lower quality level to prevent buffering. Conversely, if the connection speed improves, the player can switch to a higher quality level for a better viewing experience.

Benefits of Adaptive Bitrate Streaming

So, why is adaptive bitrate streaming so popular over the internet? In the following, we will show you the benefits of using the adaptive bitrate streaming:

Improve viewing experience: It ensures a smooth and uninterrupted viewing experience for viewers by adjusting the video quality in real-time based on their internet connection speed. This helps prevent buffering, pixelation, and other playback issues.

Broad device compatibility: Besides, the ABR is compatible with a wide range of devices, including smartphones, tablets, computers, and smart TVs. This allows content creators to reach a larger audience and ensures that viewers can access high-quality video content regardless of their device.

Provide monetization opportunities: ABR can enhance monetization opportunities for content creators by improving viewer retention and engagement. With a better viewing experience, viewers are more likely to watch ads, subscribe to premium services, or make purchases within the video content.

Scalability: It is a scalable solution that can accommodate a large number of viewers simultaneously. Content providers can easily scale their streaming infrastructure to meet growing demand and reach a global audience without compromising video quality.
