Video on demand (VOD) refers to a system that allows users to access and view video content over the internet at any time, rather than having to watch it live or at a specific airing time. VOD systems typically use streaming technology, which allows users to watch the video content in real-time as it is delivered to their devices over the internet.

Here's a general overview of how VOD systems work:

• The video content is first digitized and stored on a server. This can be a standalone server or a cloud-based server.
• The video content is then made available for streaming through a Video on demand platform, which can be accessed through a website or an app.
• When a user wants to watch a video, they select it from the platform and the video is streamed to their device in real-time. The user can pause, rewind, or fast forward the video as needed.
• The video content is delivered to the user's device through a process called buffering, where the video is temporarily stored on the device in small chunks, or packets, and played back in sequence. This allows the video to play smoothly without interruption.

There are many different types of top video on demand platforms systems, ranging from subscription-based platforms like Netflix and Hulu, to pay-per-view platforms like Amazon Prime Video and Google Play Movies & TV, to free, ad-supported platforms like YouTube and Pluto TV.
