A network for distributing broadband video content from its origination point
to
end users using a system of video servers, video storage devices, video caches
and a broadband transmission network. Video material is initially received from
content providers, encoded using a compression algorithm, and stored at a centralized
location. Depending on the projected frequency of viewing of the content, it either
remains stored at the centralized location for less frequently viewed content,
or the projected frequently viewed content is proactively transmitted to storage
systems located near the edge of the network close to the end users.
