IGS-924 24 DVB Tuner to IP-Out  
Introduction:  
The BLANKOM IGS-924 is a high performance and cost-effective SPTS or MPTS IP streamer.  
Equipped with 24 DVB-S/S2x FTA (Free to Air unencrypted) tuner inputs, with BISS de-scrambling capabilities,  
up to 2x 512 SPTS Stream channels through Gigabit Ethernet ports (parallel operation as redundant stream-  
I/O). Depending on the chosen mode, the device can operate in SPTS (IPTV) Mode or 2x12 pass through MPTS-  
Mode (DVB over IP) by selecting it (device need to reboot after changing).  
To meet customers’ various requirements, this device is also equipped with 1(2) ASI input port which selected  
services can be streamed to the Gbe output. The ASI out are only used in MPTS mode.  
The BLANKOM IGS-924 is also characterized with a high integration level, high performance and very cost  
effective. This streamer is very adaptable to new generations of IPTV headend systems i.e., in hospitality  
environments serving FreeToAir (FTA) content and BISS encrypted Services.

New Front IGS-924C (V3):  
With LCD and keypad for basic information’s: E.g.: IP address of NMS -port will be shown per default.  
To access the device, press the LOCK-button first than you can use Menu/Enter and Arrow keys.  
Difference to the old IGS-924 Version: The Power-Button is now at the Front, 1 more ASI-IN port – which can  
be used for Streaming demultiplexing as well as USB- TS-Player:  
The rear panel has different Tuner now with Loop outputs. These should only be used looping if you are  
staying on the same SAT-polarization and same Low- or High band as the one you are looping from first.  
Example: Tuner 234 are looped starting with Tuner 1:  
All are in the same Low band (22KHz=Off) and using horizontal (18V): So only Tuner 1 need to tell the RF-  
Source (SAT-Multiswitch): The 18V DC must be switched ON, the other 3 do not need to switch it on and can  
stay OFF (0V).

CATV / DVB-C LOOPINGs:  
We recommend not to loop more than 3 times (same for SAT tuner) and use an external splitter  
with a pre-installed Amplifier to give the receiver – tuner inputs normed/measured levels. For long  
coax cables please also consider the slope correction in the amplifiers to compensate the  
attenuations in higher frequency ranges.  
Safety and other recommendations:  
Assure climatic environment rules for electronic machines like this, Grounding rules as well.  
Installation should be done by a certified electrician.  
Caution:  
Before connecting power cord to Tuner to IP Gateway, you should set the power switch to “OFF”.  
Do not connect the RF-cable (F-plugs) when the unit is running.

Installation Notes  
All types of the IRENIS-BLANKOM family are 19“devices with 1 RU height designed for installation in 19”  
racks. In addition to the front panel screws, an internal module support is required at the rack.  
Depending on the Frontend used and the operating adjustments, the RF-input port carries  
DC Voltage (13V /18V, max. 400 mA).  
By connecting a mains cable, the device can become functional without any auxiliary appliances. The power  
supply units are almost (! Please check rear) designed for the wide range of 100-230V AC, 50/60Hz; a  
manual adjustment of the voltage is not necessary.  
For some models, the second power connector is feeding another independent power supply for internal  
redundancy. For a maximum of redundancy, both power supplies should use different circuits.  
All the outputs are decoupled from one another. Thus, the circuit does not have any effect on the functioning  
of the device. Connections that are not required need not to be terminated.  
Suggestion: CAT 6E Ethernet cable for Gigabit-Ethernet  
Note:  
Ipv4 global scope sessions use multicast addresses in the range 224.2.128.0 – 224.2.255.255 with SAP  
Announcements being sent to 224.2.127.254 Port 9875 (note that 224.2.127.255 is used by the obsolete  
SAPv0 and MUST NOT be used).  
Ipv4 administrative scope sessions using administratively scoped IP multicast. The multicast address to be  
used for announcements is the highest multicast address in the relevant administrative scope zone.  
For example, if the scope range is 239.16.32.0 – 239.16.33.255, then 239.16.33.255 is used for SAP  
Announcements.  
Quick-Start Installation:  
The user can control and set the configuration of the device with any computer by connecting to the web  
server-Interface (WebIF) by the 100BaseT NMS Port. The user should ensure that the computer’s IP address is  
different from other device’s IP address; otherwise, it might cause an IP conflict. Be sure to set it in the same  
network range.

Usually, the device will be shipped in MPTS mode (BYPASS) and the config-Menus are logically  
different in SPTS and MPTS  
Please select the operating mode for SPTS (default) or MPTS in the Firmware section:  
Bypass means MPTS 1:1 transponder to IP stream  
output  
Note:  
If you change the SPTS mode to MPTS (and vice versa) you need to backup your settings before the change. It  
doesn’t accept the previous saved settings from the SPTS or MPTS mode because they are different. Sounds  
logical, isn’t it?  
Just to show the difference for MPTS – outputs – only 24 IP streams can be assigned. You should decide  
whether a stream goes through GbE DATA1 or DATA2 so please balance the MPTS streams if more than 800  
Mb/s are to be streamed.  
Manually reboot is needed if you switch the modes ByPass MPTS <-> SPTS and maybe better to safe the  
config first to external file on a PC…

Select which tuner goes out to ASI:  
The package or Byte mode can be chosen…  
We select the streaming out:  
Chose UDP or RTP/RTSP to enable the multicast in parallel with the RTSP unicast (see below in this

Check whether you want to parse the CBR-stream which includes the PID8191 Zero packets for the  
Constant Bitrate or w/o Zeros as VBR-Stream:  
IMPORTANT:  
Do not use the default IP settings for the  
UDP/RTP multicast streams. At least  
increase the IP numbers. Otherwise, your  
connected L3 IGMP switch will pass all  
streams with same IP address. The Port No  
should  
be  
also  
different.  
E.g.:  
225.1.1.1:10000, next 225.1.1.2:10002, …  
VBR:  
No PID8191dec = no Zero packets  
CBR:  
with PID 8191dec

Network Setup:  
We assume that the user is familiar with IP settings and already knows his own system to connect the unit to.  
If you use the Output Streaming: We recommend using 2 separate Switches for MNS and Streams! Attention:  
The Switch must support IGMP Filtering to not overload the NMS 100 baseT port  
At least a 100BaseT for the Management NMS RJ45 port and a second one with Gigabit Ethernet  
10/100/1000BaseT with at least Layer 2+ with IGMP V2 features. Otherwise, you might flood your IP-Streaming  
network with unnecessary Data, which might overload connected IPTV STB's because they almost have only  
100BaseT capacity (Never ones use 1GbE ports) but too many inputs into a STB can result in side effects. If you  
need to select a Switch, we recommend HP Procurve 2530 24G or 48G which are cost effective, easy to  
configure, can be trunked and supporting IGMP V2. If the switch needs routing functions, the bigger brother of  
this series might be the right choice.  
Because to not accidently put DATA and NMS port in the same sub-network, the data – port setting does not  
allow this by default. Usually, the DATA GbE Ports needing at least own and free IP addresses- otherwise the  
Switch or the receivers (i.e., IPTV STB's) cannot locate the source of the streams.  
Note: DATA1 and 2 are handled by the same Network-hardware and is addressed as (Linux users  
know that):  
eth1 and eth1.1  
So, they are not fully independent but should work independently. But please assure different IP  
addresses and avoid network conflicts.

Changing a user-account:  
Change it to your needs, but do not forget the password otherwise you would need to reset the unit with the  
Front-panel RESET switch (If this model has one, press it min. 10…15 sec) to factory default.  
ATTENTION: Do not use 'special' characters like @ or % or &… for the username and the

Tuner-Setup:  
Note: DVB-C / T Tuning is slightly different and you need to enter the center- frequency of the to be  
received DVB-C/QAM channel. The tuner will detect the inside-channel values.  
NOTE: a comma in the frequency like 624,25 MHz has to be entered in AMERICAN STYLE as a ‘.’  
Instead the ‘,’  
So, we do concentrate on Satellite first:  
Basics:  
We recommend to connect every tuner RF Input to the L-Band network by  
-Using a Multiswitch with more than one SAT-position and > 16 SAT-IF outputs: You can set every  
single Tuner Input individually.  
-Using a SAT-Splitter: Be carefully, active splitter needs at least one 13V…18V DC connection to it to  
operate. You should avoid to switch on V/H polarization Voltage 13/18V on every Input port. The  
active splitter would pass the 13V or 18V to the Multiswitch and assigning the fixed polarization to  
the Multiswitch. So, all selected Transponders should be either in Vertical (13V) or Horizontal (18V)

Passive splitters should be used with DC Passthrough and the Voltage should be passed only once

the reception (or not):  
You are getting some values but do not be irritated because the real reception quality from the  
Multiswitch directly measured is shown here:  
And the IGS-tuner shows lower values:  
because it is not a real  
measurement instrument – just showing good or weak is reliable.  
If you face CC errors or disturbed pictures at TV IP receiver side it might because the INPUT SIGNAL is  
too WEAK, so you should amplify the COAX SAT Inputs. This is the case with long coax-cables which  
causing attenuation every meter by meter.  
Anyway, repeat these tuner configurations for every of the to be used inputs of the machine:

DVB-C or -T (ATSC/ISDB-Tb) Tuning:  
Of course, you need the proper DVB-tuner installed instead of SAT. Select your RF-Mode:  
Then we enter the known parameter: Modulation here DVB-C-J83A/C, Centre Freq.: 650MHz (unusual=no  
CENELEC-Channel-Plan), 6850 SR, 256QAM constellation, assure the proper dBm (dBµV) Input values in the  
Coax-cable…  
NOTE: USA/Corea are using DVB-C AnnexB (J83B) but the rest of the world DVB-C (J83 A/C).  
That’s important for the tuner setting: Frequency bandwidth and Symbol Rates! Know your mode!

We recommend not to use same MultiCast-IP Addresses but also different ones and so the ports as well:  
Bad example for GBE1+2:

Note: The both GbE outputs are some kind of mirrors and are not independent from each other. Note  
Samsung Hospitality TV’s like to start with 225.x.x.x instead of 224.x.x.x!  
So 225.0.0.1:10001 … 225.0.0.2:10002 … is a good idea. Rem.: If using RTP, please make sure the ports are  
numbered EVEN and >5000 e.g.: 225.1.1.1:5002, 225.1.1.2:5004, 225.1.1.3:5006, …  
Of course you can have other inputs like ASI to demultiplex and stream to UDP Multicast. Be sure you are  
able to switchn ON your IGMP-management in your GbE Switches to not flood the network with  
Multicast’s!!!

Recommendations:  
As a Multicast capable Switchwe recommend is the HP (ARUVA) 2530 24G or 48G.  
(For Floor switches we have an own branded one and support IGMP as well) IGMP should be set to ON in the  
port configs. The latest HP Firmware might not be the best choice. Better to test IGMP functions before  
installation into a HOT running System and eventually do a downgrade of the Firmware. This one works:  
General notes about Streams:

Note  
Host Extensions for IP Multicasting [RFC1112] specifies the extensions required of a host implementation of  
the Internet Protocol (IP) to support multicasting. The multicast addresses are in the range 224.0.0.0 through  
239.255.255.255. Address assignments are listed below.  
The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive, is reserved for the use of routing  
protocols and other low-level topology discovery or maintenance protocols, such as gateway discovery and  
group membership reporting. Multicast routers should not forward any multicast datagram with destination  
addresses in this range, regardless of its TTL.

Unicast-Prefix-based IPv4 Multicast Addresses  
Scoped Multicast Ranges  
Relative Addresses used with Scoped Multicast Addresses  
Multicast (as opposed to unicast) is used to send UDP packets from 1 source to multiple  
destination servers. This is useful for example for streaming from a satellite/DVB-T receiver to  
multiple receiving PCs for playback. Multicast can also be used on the output of an encoder to feed  
multiple streaming servers. Multicast only works with UDP and is not possible with TCP due to the  
2 way nature of TCP, most commonly multicast is used with RTP and MPEG2-TS.  
A multicast IP address must be chosen according to IANA information, we recommend using an  
address in the range 239.0.0.0 to 239.255.255.255 as this is reserved for private use. Using  
multicast addresses in the 224.0.0.0 range may clash with existing services and cause your stream to  
fail. For more details see http://www.iana.org/assignments/multicast-addresses/multicast-  
addresses.xml  
Choosing a UDP port number for multicast streams is also important. Even if you use a  
different multicast IP for each of your streams, we strongly recommend using different UDP port  
numbers as well. This is because a server and all software running on the server receives ALL  
multicast traffic on an open port and extra processing is required to filter out the required traffic. If  
the each stream arrives on a different port, the server can safely ignore any traffic on ports that are  
not open. Port numbers MUST be chosen so that don't clash with any existing services or  
ephemeral ranges. The ephemeral range for Windows Vista, 7, 2008 is 49152 to 65535, for older  
Windows it is 1025 to 5000 and for Linux it is 32768 to 61000. For more information on Windows  
see http://support.microsoft.com/kb/929851 Care should also be taken to avoid system ports 0 to  
1024. See http://www.iana.org/assignments/service-names-port-numbers/service-names-port-  
numbers.xml Generally one of the unassigned You Ports (1024-49151) should be used, you can run  
the netstat -abn (as admin under windows) command to see which ports are currently in use.  
Registered port  
A registered port is a network port (a sub-address defined within the Internet Protocol, in the  
range 1024–49151) assigned by the Internet Assigned Numbers Authority (IANA) (or by Internet

Range for Ephemeral port  
The Internet Assigned Numbers Authority (IANA) suggests the range 49152 to 65535 (215+214 to 216−1)  
for dynamic or private ports.[1]  
Many Linux kernels use the port range 32768 to 61000.[note 2] FreeBSD has used the IANA port range  
since release 4.6. Previous versions, including the Berkeley Software Distribution (BSD), use ports 1024 to  
5000 as ephemeral ports.[2][3]  
Microsoft Windows operating systems through XP use the range 1025–5000 as ephemeral ports by  
default.[4] Windows Vista, Windows 7, and Server 2008 use the IANA range by default.[5] Windows Server  
2003 uses the range 1025–5000 by default, until Microsoft security update MS08-037 from 2008 is installed,  
after which it uses the IANA range by default.[6] Windows Server 2008 with Exchange Server 2007 installed  
has a default port range of 1025–60000.[7] In addition to the default range, all versions of Windows since  
Windows 2000 have the option of specifying a custom range anywhere within 1025–65535.[8][9]

The UDP header consists of 4 fields, each of which is 2 bytes (16 bits).[1] The use of the fields "Checksum" and "Source  
port" is optional in IPv4 (pink background in table). In IPv6 only the source port is optional (see below).  
Source port number  
This field identifies the sender's port when meaningful and should be assumed to be the port to reply to if needed. If not  
used, then it should be zero. If the source host is the client, the port number is likely to be an ephemeral port number. If  
the source host is the server, the port number is likely to be a well-known port number.[4]

Destination port number  
This field identifies the receiver's port and is required. Similar to source port number, if the client is the destination host  
then the port number will likely be an ephemeral port number and if the destination host is the server then the port  
number will likely be a well-known port number.[4]  
Length  
A field that specifies the length in bytes of the UDP header and UDP data. The minimum length is 8 bytes because that is  
the length of the header. The field size sets a theoretical limit of 65,535 bytes (8 byte header + 65,527 bytes of data) for a  
UDP datagram. However the actual limit for the data length, which is imposed by the underlying IPv4 protocol, is 65,507  
bytes (65,535 − 8 byte UDP header − 20 byte IP header).[4]  
In IPv6 jumbograms it is possible to have UDP packets of size greater than 65,535 bytes.[5] RFC 2675 specifies that the  
length field is set to zero if the length of the UDP header plus UDP data is greater than 65,535.  
Checksum  
The checksum field may be used for error-checking of the header and data. This field is optional in IPv4, and mandatory  
in IPv6.[6] The field carries all-zeros if unused.[7]  
RTP:  
a part from: https://tools.ietf.org/html/rfc3550  
Chapter 11:  
RTP relies on the underlying protocol(s) to provide demultiplexing of RTP data and RTCP control streams. For UDP and  
similar protocols,  
RTP SHOULD use an even destination port number and the corresponding  
RTCP stream SHOULD use the next higher (odd) destination port number.  
For applications that take a single port number as a parameter and derive the RTP and RTCP port pair from that number,  
if an odd number is supplied then the application SHOULD replace that number with the  
next lower (even) number to use as the base of the port pair. For applications in which the RTP and RTCP destination  
port numbers are specified via explicit, separate parameters (using a signaling  
protocol or other means), the application MAY disregard the restrictions that the port numbers be even/odd and  
consecutive although the use of an even/odd port pair is still encouraged. The RTP and RTCP port numbers MUST NOT  
be the same since RTP relies on the port numbers to demultiplex the RTP data and RTCP control  
streams.  
In a unicast session, both participants need to identify a port pair for receiving RTP and RTCP packets. Both  
participants MAY use the same port pair. A participant MUST NOT assume that the source port of the incoming RTP or  
RTCP packet can be used as the destination port for outgoing RTP or RTCP packets. When RTP data packets are being  
sent in both directions, each participant's RTCP SR packets MUST be sent to the port that the other participant has  
specified for reception of RTCP. The RTCP SR packets combine sender information for the outgoing data plus reception  
report information for the incoming data. If a side is not actively sending data (see Section  
sent instead.  
6.4), an RTCP RR packet is

any port (even, not odd > 1024)  
Note: Regarding SAP (Session Announcement Protocol)  
IPv4 global scope sessions use multicast addresses in the range 224.2.128.0 - 224.2.255.255 with SAP  
Announcements being sent to 224.2.127.254 Port 9875 (note that 224.2.127.255 is used by the obsolete SAPv0  
and MUST NOT be used).  
IPv4 administrative scope sessions using administratively scoped IP multicast. The multicast address to be used  
for SAP announcements is the highest multicast address in the relevant administrative scope zone.  
For example, if the scope range is 239.16.32.0 - 239.16.33.255, then 239.16.33.255 is used for SAP  
Announcements.  
We assume, that this professional unit is used by professional technicians knowing all relevant norms,  
regulations, abbreviations (i.e. DVB, ATSC …) and specifications.
