Live Video Streaming Technologies
Live Video Streaming Technologies Live video streaming connects a camera, an encoder, transport networks, and viewers across many devices. It is a mix of capture, compression, and delivery. The main tradeoffs are latency, reliability, and cost. A clear setup helps producers reach audiences without crackling audio or frozen frames. Key parts of a streaming system Capture and encoding: from a mic and camera to a compressed stream Transport and ingest: the path from encoder to servers Segmenting and delivery: breaking the stream into chunks and sending them to fans Playback and adaptation: adjusting quality for each device and connection Common protocols and architectures Different workflows suit different goals. RTMP is a traditional push protocol used to send live video to a central ingest point. HLS and DASH break the stream into small segments and adjust quality on the fly, helping viewers with slow networks. WebRTC focuses on ultra-low latency for interactive sessions, such as live Q&A or online classes. ...
