BEFORE YOU CONNECT IT
Please make sure, your Laptop/PC is equipped with a modern Web-Browser like Mozilla Firefox.
In some cases it might be applicable to have the popup blocker disabled and adobe flash support
has been installed (Browser Preview-Window support with FLV/HLS).
The operation by/through an advanced Level 2+ or Level 3 GbEthernet –Network-Switch is
recommended supporting IGMP V2/3 protocol securing your network against flooding with too
many multicast streams.
Adjust your computer network card/interface to the same range like the factory default settings:
Example: IP Address: 192.168.1.100, NM 255.255.255.0, Gateway: 192.1.68.1.1 or other, DNS
address is not that important.
NOTE: If you have more than 1 Network-Card installed (like GbEthernet + WIFI) please make
sure –for later checking the output streams by i.e. VLC (Video LAN Client –freeware tool from
Internet)- that VLC does not recognize through which network connection it should receive the
streams. So better to disable WIFI or adjust different METRIC values to the interfaces like
GbE: Metric = 10, WIFI = 100 (lower value = higher priority)
NOTE: Regarding UDP/Multicast address ranges see at the end of this document.
Now that this has been done we start with the web-Interface access: (usually 192.168.1.168)
(Note, the address here in use has been changed by us to 192.168.1.73):
Enter the IP address in the browser:
A Login Window will appear…
Please enter username admin and password admin
Than confirm by enter button or mouse click

Leads you to the status page:
You are getting immediately the Input status of every HDMI connection and the configured
stream modes and addresses which have been setup.
It’s almost convenient if you want to check a stream:
Simply mark the stream address with mouse and copy that
by using the right mouse button:

Open VLC and paste it:
And if all is OK you should see the encoded stream:

(This example has OSD messages inserted … but we are explaining this later. ;-)
Please note: The Encoder status window gives you VLC conform UDP and RTP addresses with the
added ‘@’ in the address URL:_
So easy copy and paste is possible for the laziest ;-) to use VLC
But for other IP receivers that might be not applicable so please use the udp-address than w/o
the ’@’.
If an Input is lost or out of specification (UHD with frame rate > 30) you’ll see it in the status
window:

Or at least in the stream which outputs the Test-picture:
Another Tip: If open VLC Playlist you can use the SAP gathering to receive a network info:
Just double click on that and VLC opens the stream:

SAP is a Session Announcement Protocol that announce on a particular multicast address the streaming
info’s…
But now we should start with the global settings:
SYSTEM-SETTINGS
Password can be changed of course to secure your login.
Network –Settings can be changed as follows:
In general, the Ports for HTTP and RTSP can be kept as they are:

The MAC address might differ from the sticker at the bottom but would be re-loaded like here when RST
(RESET-BUTTON AT THE FRONT) has been pressed for approximately 10 seconds by using a thin metal
stick which fits through the hole. You can set and change this values as you like but shouldn’t conflict with
other devices in your network.
If you decide to use DHCP, you must check the units IP address from your router or Ping it by a network
tool like:
So better to keep it static ;-).
Back to system settings:

Here you do the general settings like Video and/or Audio encoding can be disabled or enabled,
For the Apple HLS stream setting of encoding values.
The TS muxer can be set as compatible to VLC or FFMPEG:
NetDropThreshold and TS once pack should be kept as the default settings,
TS values for the DVB over IP tables can be adjusted (the PIDs are counting from these start values stream
by stream (Main + secondary’s 4x4) , TS service name/provider which will appear in the tables and you
can add zero packets to the Stream to fill it nearly as a constant bitrate stream being compatible with
some IP to DVB modulators which might need that PID 8191dec in the TransportStream (TS).
The TS Stream can be secured by a password which would be asked by VLC if you open that stream:

The username and PW are the same like your login data: admin/admin
Vmix compatibility … actually I do not know for what kind this settings are:
The Multicast Type must be selected for all of the encoder parts in general: UDP or RTP.
An explanation about the RTP default specifications can be reviewed at the end of this document. Hint:
RTP used a parallel stream and your default port number like rtp://225.1.1.1:5004
Should be an even number and greater than 5000. Because the CRC parallel stream will be sent via
Even-port-No. +1 (here in this example: 5005) The Receiver will take care about the content, time stamps
and correction try using the parallel RTP packet info stream.
The RTPS can be sent as ‘Elementary’ or simple TS format:
UDP TTL (Time to Live) can be adjusted to your needs.
This Buffer size should be kept as it is….
Additionally these settings can be used for picture improvements:

If you finally press the
Button this message appears and mean: Your IPTV receiver need to re-join the stream
because of the changed modifications of your new setup:
If problems happen with a moving camera picture or fast movements:
Please check the Deinterlacing mode and change
accordingly to this ‘Bottom only’usage

These settings are nearly self-explaining:
Of course for a scheduled ‘Overnight’ reboot action you should have NTP enabled…
The Update-file will –in case of new fixes and features are released by the developers, not published in
our web-pages, so if you are facing problems we recommend to contact us giving information which
version is already running in the devices like screenshots:
Which will help our support team to recommend new firmware or not.

ADJUSTING THE ENCODERS
In these menus you can set the different values according to your preferred output streamings:
h.264 or hevc/h.265 compatible codec usage.
Note: h.265 / HEVC safes in average 35% bandwidth by having the same picture quality as h.264
But HEVC needs more comuting power in older receivers löike PC#s and VLC because they decode in
software not using the CPU hardware decoders inbuilt. Nowadays the hevc codec is implemented in
hardware decoders in many devices and if you use a SetTopBox as receiver you need to check whether it
can decode HEVC.
Please always have an eye on the status information when you enable more and more streams:
to monitor the CPU capacity and
BTW:
The NTP time can be adjusted here by clicking on the link.

Many downscaling formats can be chosen.
The encoding process CBR (Constant) will consume more CPU power than the variable (VBR) processing:
but outputs a better quality.
Hint: To have nearly same quality like the Input:
If the source is coming in as:
You should adjust the encoding also to a multiple of the framerate like here 25 fps.
Or 50 ;-).

25 would be better.
Substream settings can be adjusted accordingly:
And of course you can change the Codec profile to your needs.
