A Video Content Delivery Network delivers live and on-demand, high-quality videos to web-connected devices over a large geographically dispersed network of servers. The major strength of Video CDN is the caching concept. When a viewer submits a request, the server caching content near the user’s location delivers the video. This will accelerate the delivery.
Aside from traffic management, CDNs and video streaming server technology offer benefits to both network operators and consumers alike:
1. Operators can add new revenue streams by selling video CDN services to enterprises and third-party content owners, while also improving average revenue per subscriber.
2. Consumers enjoy a more reliable and seamless video experience.
As per the domain of network service providers, they make use of a Video-on-demand server as well as IPTV server to deliver high quality video contents and ensure seamless performance from media streaming software anywhere in the world. The network service providers use a specialised server that delivers video content such as movies and television shows over the internet, in response to requests from users with internet-connected devices such as PCs, tablets, or smart phones. VOD server technology is often incorporated into a content distribution network (CDN) that stores the video content on multiple widely dispersed servers in order to effectively handle the high traffic volumes generated by on-demand video streaming and live video streaming.
An IPTV server delivers television services over a local access network (LAN) or the Internet via a communication method called Internet Protocol (IP). These secure packet-switched networks are access agnostic, which means all transmitted content, including audio, video, text, images, and data, can be viewed on any connected device. A video streaming server delivers video content over the Internet to a user with a computer, smart phone, or other connected device.
Network service providers that deploy their own video CDN can reduce subscriber churn by:
1. Reducing traffic on the primary network, which improves video content and web performance overall.
2. Creating and deploying value-added, targeted services to attract new customers and retain existing subscribers.
Television services offered through IPTV server technology are subscription based and fall under three broad categories:
1. Live TV, which may or may not allow interactivity with the show currently going live
2. Time-shifted TV which includes catch-up TV that replays shows from a video streaming server. The show must have been broadcasted hours or days earlier or start-over TV that replays a current show from the beginning.
3. Video on demand (VOD), allows subscribers to select and view videos from a catalog / library. This content, delivered via VOD server technology, is not related to television programming but can include archived recordings of network shows and series, along with movies, educational videos, and independent films. Some content providers also produce their own made-for-TV series but only make these available to their VOD subscribers.
Basically, the client requirements for hosting a media based website or applications surely requires a hosting solution. This keeps open the availability of server resources in a scalable manner. Video CDN technology can be used in the hosting platforms. New redundancy and geographical clusters are employed in order to add the disaster recovery norms of such high resource using environments.
