Virgin Media's VOD platform is built around a contention ratio of around 16:1 (whilst at the same time delivering hundreds of linear TV channels). Virgin Media achieves this contention ratio through the "segmentation" process by putting video server

equipment deep into its network and only sharing bandwidth between 1000-4000 customers.
