Why TCP/IP for Distributed Video?
NetStreams’ vision for distributed video is one that consistently distributes high definition
video (up to 1080p) in an all digital format using TCP/IP on any standard switched Ethernet
network. This is the backbone of StreamNet. By distributing
video over TCP/IP, drastic improvements in flexibility, scalability,
and price / performance are achieved over traditional video
distribution methods. In addition, the incorporation of a distributed
architecture and distributed intelligence allows for flexibility and
easy expansion, since A/V sources may still be located at the head
end (like RF and Baseband systems), OR located anywhere on the
network.
Since TCP/IP was primarily developed for data transmission
across a network, ClearOne had to solve fundamental challenges
with using the protocol to distribute video. For example Network
bandwidth is a constraint to quality as packets may be lost if the
network is not managed correctly. Additionally synchronization
of signal distribution is essential and backwards / forwards
compatibility with legacy and newer sources always presents
issues.
Only ClearOne has been able to solve all of these issues and
distribute the highest quality (1080p), uncompressed video,
point to point, and point to multipoint over TCP/IP on an Ethernet
network. NetStreams’ IP-Based system is the most advanced and
expandable distributed video system ever built.
