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
