CW-4000
USER'S GUIDE
Dear User!
Today the digital television broadcasting is
unimaginable without up to date EPG (Electronic Program
Guide). As the transmission standard for the EPG data is
different from of the video and audio data streams;
remultiplexing the transport stream requires another device
for recompiling the EPG data stream.
The CW-4955 type 64-Channel EPG Remultiplexer is
the auxiliary device of the transport stream remultiplexers,
that allows affixing an EPG recompiled by the user to the
transport stream compiled by the user. The device is
capable of selecting the EPG data streams from the input
transport streams for 64 TV programs (Service). The 64
separate data streams can be added to the TS one by one at
SPTS. At MPTS, group can be organised for adding it to
the TS. In case of MPTS the device can make EPG for 8
transport streams on the average.
The device receives the input EPGs at 60 IP and four
ASI inputs. The output EPG data streams can be joined with
the TS as unicast or multicast data streams.
1. MECHANICAL CONSTRUCTION
The CW-4955 64-Channel EPG Remultiplexer is
built in standard 19" x 1 HU instrument frame. It is
delivered along with the following accessories:
1. Power cord 1 ea.
2. Spare fuse T 1,25 A
(placed in the fuse holder mounting) 1 ea.
3. Crossover cable with RJ45 connectors 1 ea.
4. Cover cap for the optical receptacle 2 ea.
2. ELECTRICAL CONSTRUCTION
The device is equipped with own switching mode
power supply. The supply voltage of the interface
circuitry is +3.3 V, but the signal processing circuitry
works with supply voltages of +1.0, 1.8 or +2.5 V. The
real power consumption is low the unit is suitable for
continuous operation. The low consumption needs no
special heating, the normal environmental temperature
(20...22°C) and natural ventilation will significantly increase
the lifetime and reliability of the device.
The device circuitry comprises high complexity
FPGA circuits, which should be configured to the given
task by the user. The device can be configured with
the software, free available for downloading from the
www.cableworld.eu web site. This product of
CableWorld Ltd is the member of a new generation,
where the instruction set is different from the previous
releases. The compatibility with the previous software
is only so much, that the device sends a response to
the SW-4901 software Gigabit query, so at querying
the network devices the CW-4955 indicates the
presence. The programs run in Windows XP or Vista
environment, but the open system of CableWorld
allows controlling the devices by anyone, from any
environment with his own software via IP.
3. HARDWARE AND SOFTWARE SUPPORT
The SW-4955 64-Channel EPG Remultiplexer
Controller software for programming the device can be
downloaded from the ‘Software’ page of the
www.cableworld.eu web site. The downloaded installer
exe file installs the software in the C:\Program
Files\CableWorld\ SW_4955 directory. This item of
software can be simply removed with the ‘Uninstall’
function from the PC any time, so it can be installed for
preliminary test, too.
The user’s guide of the software and the detailed
user’s guide for the device can be found in the ‘Help’
of the software. The ‘Help’ can be downloaded in pdf
format from the ‘Software’ page separately, to
All the parameters of the 64-Channel EPG
Remultiplexer can be set with the SW-4955 software.
Putting the device in operation requires no additional
software. For finding the IP network devices the finder
of the SW-4901 can be used, other software can not
communicate with the EPG Remultiplexer.
For examining the input and output streams we
suggest installing the SW-4811B TS Analyzer
software, but other manufacturers’ software can be

used, as well. It is useful, if the printed form of the
software Help file is available, too. In our latest guides
the important steps are emphasized with large letters
and pictures, those interested in the details are
informed with small letter descriptions.
After installing the software, the device and the PC
can be interconnected with the attached crossover
cable in 100Base-T mode for studying. But we suggest
interconnecting the device and the PC via switch with
straight cable in order to supply the external data
streams as soon as possible. The connection with 100
Mbit/s rate can be used until the transport streams fit
in this data rate, beyond this, change to gigabit data
rate. In the first tests simple switches can be used, but
we suggest using switches that are suitable for
managing IGMP messages as soon as possible.
The factory setting for the 64-Channel EPG
Remultiplexer input is IP address 10.123.13.101, for
the output is IP address 10.123.13.102. When using
several devices, set different IP addresses as soon as
possible to avoid IP address conflict. Users find help in
descriptions CW-Net.pdf and Using_CW-Net.pdf,
which can be downloaded from the ‘Papers’ page of
the web site. The basic parameters of the CW-4955
(IP Address, MAC Address, etc.) can be set in the Full
version of the SW-4955 software on the System
Configuration page.
Probably, transmitting the transport stream over
IP network holds surprises even for users having
good networking knowledge. The most important
knowledge is summarised in the publication ‘Transport
Stream Managing over IP’ (TSMoIP.pdf).
Important note: The gigabit system of CableWorld
is a very advanced, high performance system, where
the transport streams and the device control
commands are transmitted in a common network;
decreasing your expenses and increasing the potential
of remote control. The transport streams and the
control commands are selected according to the Port
numbers. The user’s job is, assigning the Port number
range to be used for transmitting the TS and
programming it in the device. The device control must
be performed outside the TS Port Interval. The device
control can be totally disabled by the transport streams
outside the TS Port Interval.
In the CableWorld’s system the gigabit
transmission is performed by FPGA circuitry, so the
data rate is not limited by the performance of the
internal processors, and the gigabit data rate can be
utilized up to 100%.
4. PUTTING THE DEVICES IN OPERATION
After unpacking remove the protection foil from the
stainless steel cover of the device. Connect the device
to the specified mains voltage and switch on the power
switch. After a few seconds (max. 60 sec) the device is
ready to operation.
Programming the device and saving the settings is
required only when putting the device in operation first
or when modifying the settings.
5. TECHNICAL DATA
The technical data of the devices are published
in their data sheets, which are available at the web
site www.cableworld.hu.
The novelty of the A CW-4955 is, that besides
the UTP cable, the optical cable connection is also
possible. When optical cable is used, remove the
protective plug from the SFP housing, then gently
slide the SFP module according to the required
transmission (distance and wavelength) in place. The
supply voltage of the module is +3.3 V, the maximum
current consumption is 300 mA. After connecting the
optical cable the device will prefer the optical
transmission and will switch over to the UTP input
only, if the communication is unsuccessful.
The consumption of the optical modules is high, so
if the optical input is not used, do not store the module
plugged in the SFP connector. After removing the
module, put back the protective plug.
Additional technical data:
The CW-4955 is equipped with loop-through ASI
inputs, but despite the plastic BNC house, the external
parts (shield) of both the input and output BNC
connectors are connected to the device frame. The
isolating transformer here is used only for balancing
the signal.
