Video on Demand
& Virtual Cinema
Planet Vision
Video on Demand Server is built on
an industry-standard platform and supports over 100 concurrent streams (1000
subscribers at normal VoD peak take-up rate) at typical MPEG-2 compression rate
of 4 Mb/s per stream. Both unicast and multicast modes are supported.
Server storage
comprises four hot-swap SATA-II hard disks. The total HDD space in the standard
configuration is 3Tb (Terabytes) or more than 800 movies in DVD quality. External data
storage can be connected where required.
Movies are
stored in MPEG-2 or MPEG-4 AVC transport stream or program stream - both SD and
HD are supported. Compression rate can be modified to match set-top box and/or
downstream network performance.
Video content
can be loaded via smb or ftp. We have included a module for transcoding DVDs
into the required format direct to the HDD of the server. This module is
available in the command line mode to automate transcoding the disks.
Movie
descriptions, displayed in the Middleware user interface, can be synchronized
with a central database on the Internet (Media Knowledge Base,
www.media-kb.com). The database contains the
full and structured information on multimedia content, is multilingual and
freely accessible.
The server is
implemented in a 1U rack-mount case. It is possible to connect
VoD servers into
a cluster. This allows our customers to achieve almost any performance and
provide VoD in distributed networks.
Using
Planet Vision
CAS allows to stream
already encrypted media content from the VoD server.
Time Shifted TV,
Network Personal Video Recorder, and TV on Demand are implemented as a separate
server based on the same framework.
