When we discuss rethinking broadcasting in a streaming world, we all acknowledge that we’ve redefined what TV really is. It’s now a content-first, consumer-choice smorgasbord, and streaming companies -- whether digitally native streaming behemoths like Netflix, or latecomer niche players or broadcasters who didn’t realize the streaming wave was a tsunami -- exist to cater to them.
Sometime during the 2020-21 Covid-19 pandemic, video streaming, which had already gained a foothold in terms of mass-market entertainment, took a big lead over linear TV. Consumers started cutting the cord en masse, as they’d long been predicted to do. A proliferation of digital-first content providers and robust streaming technology coupled with people being stuck in their homes for what felt like infinity created the perfect conditions for OTT video streaming to take what’s traditionally been the domain of TV broadcasters by storm.
When delivering video over-the-top (OTT), the internet is the principal highway for distributing this content. However, OTT streaming delivery requires something faster than what the internet offers in terms of how chunks/fragments are supposed to flow.
