Question: 1 / 400

What is the impact of using ABR on video quality for the viewer?

It standardizes quality across devices

It progressively adjusts based on network performance

Using Adaptive Bitrate Streaming (ABR) significantly impacts video quality by enabling the stream to progressively adjust based on the viewer's network performance. This adaptability means that if a viewer's internet connection is strong, the video can automatically switch to a higher bitrate, providing a clearer and higher-resolution picture. Conversely, if the connection weakens, the streaming quality will adjust downward to maintain playback without buffering. This dynamic adjustment enhances the viewing experience by prioritizing smooth playback over consistently high quality, ensuring that interruptions are minimized and viewers can continue watching seamlessly, even when network conditions change.
