Server (video)

A storage system that provides audio and video storage for a
network of clients. While there are some analog systems based on optical disks,
most used in professional and broadcast applications are based on digital disk
storage.

Aside from those used for video on demand (VOD), video servers are applied in
three areas of television operation: transmission, post production and news.
Compared to general purpose file servers, video severs must handle far more data,
files are larger and must be continuously delivered.

There is no general specification for video servers and so the performance between
models varies greatly according to storage capacity, number of channels,
compression ratio and degree of access to store material--the latter having a
profound influence.

Store sizes are very large, typically up to 500 Gigabytes or more. Operation depends
entirely on connected devices, edit suites, automation systems, secondary servers,
etc., so the effectiveness of the necessary remote control and video networking is vital
to success.
