cated fiber networks or the predictable reliability of traditional live satellite transmission. This is because they cannot guarantee in-order arrival and sustain high bitrates over long distances. Commodity networks such as WAN, internet and wireless (including Wi-Fi, 4G, LTE and 5G) have inherently higher round-trip time and packet loss for which today’s solutions require adding signifi- cant latency or costly workarounds. Traditional TCP-based approaches like adaptive bitrate (ABR) streaming over HTTP can work very well for distribution, but induce significant latency, often resulting in lower quality video and a diminished user experience. ABR is also opera- tionally complex, requiring all video sources to be encoded into multiple bit rates with additional storage and encoding costs. Traditional FEC is highly bandwidth inefficient and introduces additional latency. Even with the most efficient error correction coding, live point-to-point deliv- ery requires up to 25% more bandwidth, is sig- nificantly delayed, and reliability is dependent on network conditions. Changing the economics of live streaming 64 • Broadcast Beat Magazine • Using an innovative approach to delivering broad- cast-quality video streams from the venue to the production facility in real time enables new work- flows once thought impossible. Creative teams can begin working on a live capture feed from a remote location – across the country or around the world – while the event is taking place, with- out the delay of a file-based workflow. Editing, transcoding, packaging, and other downstream workflows can start immediately, significantly shortening the production cycle and enabling media organizations to immediately monetize their assets. This enables all kinds of media organizations to achieve cost-effective, high-quality live stream- ing, eliminating the need for expensive, pro- prietary backhaul infrastructure, transport and distribution, and significantly reduces the cost of remote productions. By lowering production costs, it enables media companies to create and deliver targeted content for new audiences. We see the ability to deliver high-quality video over commodity internet as an industry breakthrough that changes the economics of video contribu- tion.
