will obviously block the execution. Unfortunately, the fact that the web
frontend relies on Java means that common Android or iOS devices
cannot be used to configure the CW-4412.
9. START – WELCOME: A welcome screen is always nice. CableWorld
uses this space to give a description of the device. This may seem
unnecessary, but in a crowed head-end with lots of different devices
you will quickly benefit from getting such a welcome screen, since you
will immediately know, which device you just connected to.
10. START – QUICK
SETUP:Hereyou can set up all relevant parameters
in three tabs, which correspond to the CW-4112’s block diagram: it is
composed of a LAN interface and two separate encoders. The only
possible confusion should be avoided at this point: the LAN Settings
refer to the IPTV output settings, not the IP of the web-frontend.
11. The quick setup screen for encoder 1. Here you can specify the
input source and input format, as well as the output format. Notice that
the CW-4412 can down-convert a resolution, but obviously it cannot
up-convert a low resolution to a higher one: just use a high enough
bandwidth for best image quality and you make viewers happy.
12. The setup screen of encoder 2 is naturally exactly the same as the
previous, as both encoders have equal characteristics. Notice that the
web-frontend will indicate if an input signal is preset, if the encoder is
doing its job and if IP streaming is activated.
13. START – SUMMARY: These pages give you a full insight on the CW-
4412’s configuration and status. Organized in several tabs, the first one
gives all information relative to the network configuration.
14. Next is the tab of the first encoder. Check marks tell immediately if
everything is OK.
15. This tab shows information regarding the network output of enco-
der 1. Notice the first line in the picture: in this case, the encoder was
not configured to output anything over the network. Also, you can see
that the configured mode was Multicast, rather than Unicast.
16. The information tab of the second encoder, everything was OK.
17. But I also had not activated the streaming output over the network,
when this picture was taken.
18. ENCODER – INPUT SETUP: Two tabs allow the independent configu-
ration of each encoder. Just tell what signal input should be used and
if you require to down-convert a resolution, you can configure that too:
imagine you want to read a Full HD resolution on the HDMI input, but
only generate a MPEG-4 stream with a SD resolution: no problem for the
CW-4412.
