USER'S GUIDE
Dear User!
As a heritage of the analog technology a number of
program sources are still supplying composite PAL or
NTSC video signals (video players, local studio cameras,
etc.). The encoder series of CableWorld transmit these
analog signals into cable or IP-based broadcasting
networks in MPEG-2 packed format.
1. MECHANICAL CONSTRUCTION
The MPEG-2 Encoders are built in standard
19"x1 HU instrument frame. They are 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.
The power consumption of all types is very low
therefore no special cooling or ventilation is
needed.
2. ELECTRICAL CONSTRUCTION
The devices are 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
+1.2 V or +2.5 V. The real power consumption is
low, the unit is suitable for continuous operation.
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.
The devices and the software of CableWorld Ltd
form a system, where one program can be used for
many devices, and some devices need several
programs. 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 software for programming the devices 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 directory. These items
of software can be simply removed with the
‘Uninstall’ function from the PC any time, so they
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, too.
Programming the MPEG-2 Encoder requires
installing the SW-4888 basic software and the SW4901 auxiliary software (only for the CW-498x IPoutput versions). For examining the output stream
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 the first tests simple switches can be used,
but we suggest using switches suitable for
managing IGMP messages as soon as possible.
The factory setting for the MPEG-2 Encoder is
IP address 10.123.13.101. When using several
devices, set different IP addresses with the SW4901 software 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.
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. Within a few seconds 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.
Additional technical data:
All ASI inputs and outputs are insulated by
transformers, which assure 2000 V separation. This
design is very advantageous in applications, where
arising of earth currents due to transmission of the
ASI signal between different rooms or laboratories
have to be prevented.
From the point of view of electromagnetic
radiations and protection against disturbances, it is
advantageous if the outer shielding of the ASI
connecting cable is earthed at a proper point. This
point has to be found individually in each
application.
In the CW-4000 system of CableWorld the ASI
inputs have metallic BNC connectors, the shielding
of the coaxial cable is earthed here. The output
connectors are insulated.
6. SUPPLEMENT
We appreciate if the users are going to integrate
our products into their system and undertake writing
own software for operating these products.
CableWorld assure extra technical support for the
creative users; in the CableWorld’s system the
instruction sets are free available for everyone, and
major users can have the source codes of the
software, too.
Beyond serial products, CableWorld is ready to
deliver products for special demands and
implement individual ideas.
We appreciate receiving all remarks,
experiences, measuring results with our products
and we pay respect to them at our further
developments.
