Public Internet
The DEVOS server can "pull" and "push" live streams over the public
Internet, and can deliver content to public viewers via the public
Internet if so configured. To the extent the network is configured to
enable this, special attention should be paid to public Internet
bandwidth usage.
DEVOS and DVExpress can stream live video to YouTube and Facebook
as well as delivering video directly to viewers.
Network Bandwidth
Network bandwidth use is equal to the total number of simultaneous
viewers multiplied by the bit rate of the content being viewed. For
example, 100 viewers of a 500 Kbps stream would require 50,000 Kbps
(50 Mbps, or 50% of a 100 Mbps Ethernet, 5% of a 1 Gbps Ethernet).
Special attention should be paid to WiFi deployments to ensure
networks do not become oversubscribed.
DEVOS Cloud
DEVOS is available where the server is hosted by Discover Video on the
public Internet. In this case, all IP signal flow travels over the
customer's public Internet access connection, and special attention
should be paid to local capacity issues. Note that for live video
distribution, these issues can be mitigated by installing a
StreamPump
®
at the customer premises location(s).
