In the previous article in this series, “Understanding OTT Systems”, we looked at the fundamental differences between unidirectional broadcast and OTT delivery. We investigated the complexity of OTT delivery and observed an insight into the multi-service provider silo culture. In this article we fully analyze a typical OTT delivery channel to understand why we need monitoring.

Even delivering an OTT unicast program to a mobile device or player requires a bi-directional data path between the broadcaster and the viewer. And this is one of the reasons OTT can provide many challenges for broadcasters, especially when multiple service providers are involved.

There are five distinct technical areas in the OTT delivery chain; content provider or broadcaster, content preparation and origin services (also known as the headend), private or 3rd party CDN’s, Mobile/Wi-Fi/Broadband access points, and the user device (laptop, mobile phone, notepad).

The broadcast is made available by the content provider, but it is the user that initiates the transmission and delivery.
