Last spring, I was watching my two college basketball teams, West Virginia University (WVU) and the University of North Carolina (UNC), in the NCAAs. I kept jumping between streaming games withYouTube TV and Sling TV and cable-carried games on Charter/Specter. A big difference quickly became plain. The streaming games were up to 30 seconds behind the cable cast games.
Why? It's because streaming video is chopped into 10-second chunks. Your Roku or other streaming device usually wait for three segments to arrive before playing them for you. That's fine for watching Better Call Saul. It stinks for

watching a last-second fast-break when your friend calls to offer his congratulations before you see the end of the game.
Limelight Networks thinks it has the answer: Limelight Realtime Streaming. The company promises that it can eliminate long delays and enable producers to stream live video from anywhere in the world to anywhere in the world in less than a second. This will provide online viewers with the same experience enjoyed by broadcast viewers.
Technically, the internet-streaming problem starts with HTTP streaming formats, such as MPEG-DASH and HLS, which break the video into small segments that must be buffered before playback. You can reduce the size of the chunks to minimize the delay, but that has led to video buffering and other playback issues.

Ironically, the eternally insecure Adobe Flash was better at streaming. But, as the joke goes, it's a good day when you don't have to patch Flash. In any case, few streaming providers still use Flash, and Adobe is ending Flash support in 2020.
Limelight's answer is the open-source WebRTC technology, which delivers reliable, broadcast-quality, real-time video streaming over the UDP data transfer protocol. WebRTC started as a protocol to deliver reliable and fast real-time communications for web browsers. It's supported by all the major browsers, except for Internet Explorer (IE).
