2. INTRO
Congratulations on purchasing the MLH-201. You now own a high quality, professional
DTV headend. To get the most out of your purchase, please take the time to carefully
read through this manual.
3. INSTRUCTIONS
3.1 - Description
The MLH-201 is a very powerful, all-in-one mini headend device, able to receive up to
4 HD signals and convert them either in IPTV streaming using UDP/RTP protocols mul-
ticast/unicast.
The embedded web server of the MLH-201 provides a very friendly user interface as
well as the ability of remote or local control of the device via LAN.
Its small size and its powerful features render the MLH-201 the ideal solution in case
we want to distribute HD content eg. coming from STBs or blue ray to a CATV instal-
lation using the IPTV technology.
3.2 - Features
zx w 4 x HD inputs
zx w HDCP v1.4 support
zx w Gbit IP streaming (up to 64 x SPTS / 4 x MPTS)
zx w Dual power supplies offering redundancy mode
zx w Local or remote control via webserver
zx w Very friendly user interface
zx w Wall or rack mount options
zx w SNMP v2
zx w Ultra-compact size
zx w 5-year warranty
3.2.1 - Auto-reset functions and watchdog
During the normal operation of the MLH-201, the main CPU monitors all the internal
parts in order to ensure that the device works normally. In case of an internal error or
module failure, the MLH-201 immediately initiates the recovery procedure by resetting
the appropriate module or the device. Finally, watchdog timers ensure that the device
will be reset in case of CPU failure..

5
3.2.2 - IP streaming
The MLH-201 is able to make IP streaming of all programs coming from the 4 x HD in-
puts using UDP or RTP protocol in multicast/unicast IP addresses. The max. output bi-
trate can be up to 480 Mpbs.
3.2.3 – Dual power supplies
The MLH-201 is powered from one or two external power supplies of +12VDC/2.5A. In
case we connect two external power supplies then they will work in redundancy mode.
Thus, in case of failure of one of the two external power supplies the device will con-
tinue working without stoping.

This page depicts all programs coming from the 4x HD inputs and their settings.
For each program the MLH-201 provides the following information:
zx w Service Name – which is the name of the program
zx w Service ID – which is the Service ID number of the program
zx w LCN No – which is the logic channel number of the program
zx w Bandwidth – which is the bitrate of the program
Using the Drop down menu from “Output” column (Figure No 6) the user is able to as-
sign any program to any of the four outputs. By doing the same process for each pro-
gram, from all inputs the user is able to create the four custom multiplexes in device’s
output.

Figure No 7
The status section in (Figure No 7) provides a general idea to the user of the current pay-
load (according to the selected programs) comparing to the max. output payload.
It is recommended that the user must not exceed the 85% from each output, since all
the bitrate are variable according to their specific content.

In Figure No 8 we have general settings of the IP streamer as follows:
zx w IP address: This is the IP address of the streamer for ping purposes.
zx w MAC address: This is the MAC address of the streamer
zx w IGMP: The user is able to select IGMP v2 or v3 or disable the IGMP.
The Status section provides a general view of how many programs and in what format
are currently being streamed from the device is its four outputs.
Peak Detection mechanism
As shown in Figure No 7 there is a colored indicator of the peak detection mechanism,
for each output transport stream. This indicates if any overflow has occurred on IP
streamer’s output bitrate with the following colors:
zx w Green – No overflow occurred
zx w Yellow – No overflow occurred but the input bitrate is close to the output bitrate
zx w Red – Overflow occurred. The user must decrease the input bitrate
4.2.6 - “IP streaming” page
In “IP streaming” section the user is able to setup the IP streamer of the device.
Figure No 8

13
In order to setup the IP address for each program there are four tabs one for each IP
output of the MLH-201.
By selecting e.g. the TS1 tab (Figure No 9) the user is able to setup the IP streamer for
this specific output, following the steps below:
1st step: Select SPTS or MPTS streaming mode.
SPTS mode: Means that each program has its own IP
MPTS mode: Means that all the programs of the current output (e.g.
TS1) will be streamed in a single IP.
2nd step: For each program (in SPTS mode) or for the whole TS (in MPTS mode)
the user is able to assign a multicast IP address from 224.0.0.0 to
239.255.255.255 or a unicast IP address as well as its destination port
and protocol (UDP or RTP).
By repeating the above procedure for all four outputs of the MLH-201, the user is able
to setup the IP streamer of the device.
