VOD (Video on Demand) and OTT (Over-the-Top) are two methods of providing digital video content, that are becoming increasingly popular. VOD and OTT have some similarities, as both are technologies used to stream and deliver digital video content. However, there are also differences between the two, which makes them suitable for different use-cases.

Video on Demand (VOD)

VOD is a system that typically works within a closed network, such as the cable television industry. It allows users to select from a library of stored digital video content which is then delivered to their devices in real-time. This means that users have to wait until the content is available before they can watch it, which limits their browsing and viewing flexibility. In addition, VOD content is generally expensive and not always up-to-date with the latest releases.

Over the Top (OTT)

In comparison, OTT (over-the-top) content is delivered via the internet. It allows for the streaming of online video content across multiple devices such as mobile phones, tablets, PCs and Smart TVs, without the need for any additional hardware or software. OTT content is generally faster and more up-to-date than VOD, and often cheaper due to the lower distribution costs. Furthermore, due to the nature of the internet, OTT users can access content on-demand, with no waiting time for downloads, enabling them to browse and watch content in real-time.

In conclusion, VOD and OTT are both technologies used to stream and deliver digital video content. VOD is ideal for traditional cable television networks, due to its closed system approach, whereas OTT is ideal for streaming digital content globally, as it allows for faster delivery of up-to-date content and reduces distribution costs.
