When Alice turns her smartphone camera on herself and says “Hello, world!” in her kitchen, a segment of that video is encoded and compressed so that the same digital data can be sent out over the Internet to dozens or millions of viewers at once. This takes a little more time than downloading a short PDF or image file, so live stream video is typically delivered with a few seconds of latency.
A youtube live stream is a real time video broadcast that can be seen on any device with a browser and internet connection. It’s a great way to connect with family and friends, especially when you can’t physically be there.
A CDN then caches – temporarily saves – each segment of the live stream, so that most viewers can watch it from servers closer to them, which cuts down on the round-trip time to and from the origin server. Bob’s smartphone receives and decodes the segmented video data, and Alice’s kitchen wall appears in his frame of view on his phone. youtube live stream views buy
