2. Encoder: Encoding includes compressing the stream down for quick supply throughout the web. Encoders might be {hardware} or software program — out there each free or for buy, relying on what you’re attempting to realize.
3. Server: As soon as encoded, the packaged stream is transported to a media server, the place it may be transcoded for adaptive bitrate supply and repackaged for supply to a number of units. An audio stay streaming server software program or cloud streaming service might be employed to perform this and extra.
4. Technique of supply: Until you’re streaming to a handful of listeners, a content material supply community (CDN) is usually employed for international distribution. Free streaming platforms like YouTube Stay typically have their very own CDN or associate with one other supplier.
