Video Streaming Architecture: Delivering Smooth Viewing
Video Streaming Architecture: Delivering Smooth Viewing Video streaming aims to move a video file from a creator to a viewer with smooth playback. A solid architecture serves many devices and networks. The goal is fast start, steady quality, and few pauses, even when bandwidth changes. How a streaming pipeline comes together A streaming system works in four parts: encoding, packaging, delivery, and playback. Each part plays a key role. Ingest and encoding: the source video is captured and encoded into several quality levels. Packaging and manifests: the video is wrapped into formats like HLS or DASH and paired with a guide, the manifest. Delivery network: content travels through servers and often a content delivery network (CDN) to be close to viewers. Player and ABR: the app on the viewer’s device reads the manifest, measures speed, and picks the best quality. Adaptive bitrate streaming in practice Adaptive bitrate streaming (ABR) creates a ladder of quality levels. The player monitors bandwidth and buffer health, then switches up or down as needed. With ABR, a viewer with a strong connection sees higher quality, while a slower link avoids long rebuffering. Formats such as HLS and DASH support this approach. ...
