3.3.2 Turnkey MV-805 Hardware-Optimized Software
Inside a turnkey MV-805, a hardware-optimized SAM IP multiviewer software application
implements the MV-805’s “multiviewer functionality”. This uses the media IP network
interface(s) for
all
media IP streams (In and Out) and it uses further network port(s) for
connection to a control IP network for control/servicing.
IP streams (in or out) connect to ‘spigots’ on the IP multiviewer software application.
Each video input IP stream is taken from the media IP network interface by the software
application. The final multiviewer display output image is formed and provided as a video IP
stream to the media IP network interface.
Figure 3 shows the connection of the MV-805’s multiviewer software application to the unit’s
external interfaces.
Destination Spigots:
Each input spigot of the IP multiviewer software application looks for a specific multicast IP
stream from the media IP network interface(s) and takes those multicast data packets. Thus,
all multiviewer video inputs are acquired by each spigot.
Source Spigots:
Each output spigot packetizes all or part of a multiviewer display output image and sources a
multicast IP stream containing a video wall. This is sent out via the media IP network
interface(s).

Note:
MV-805-16 has two media network interfaces, 1A and 1B.
MV-805-32 has four media network interfaces, 1A,1B, 2A and 2B.
(i.e. the MV-805-32 has twice the network interface bandwidth.)
