with the viewer often watching with a 20-40
second delay to Live TV.
In addition, the further the subscriber is
from the streaming server the more the
delay as the bitrate deteriorates and so the
video quality suffers. Major international
providers have to address the problem with
thousands of cascaded CDN (Content
Delivery Network) servers around the world.
This shortens the effective distance from
server to subscriber but is very expensive
and doesn’t resolve problems with delay to
Live TV and slow channel change.
Qarva’s aQua Video Server running
MultiPipe addresses this problem. Qarva
Multipipe enables the subscriber to use the
whole bandwidth of the local Internet
connection for accessing video even from
another continent, even in HD.
Qarva Multipipe protocol is based on
TCP/IP. The proprietary protocol divides
the stream in to multiple sub-streams then
uses persistent connections to multiple
