USER'S GUIDE
The MPEG-2 compression that brought a revolutionary
advance in the transmission of picture and sound, by
today was superseded by the MPEG-4 compression
technique. On the customers’ intensive demand
CableWorld developed the new generation of its
encoders, the MPEG-4 (H.264) Encoder series.
1. MECHANICAL CONSTRUCTION
The MPEG-4 Encoders are built in standard 19"
x 1 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 in all versions 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, whereas the signal
processing circuitry works with supply voltages as
low as +1.2 V, +1.8 V and +2.5 V. The effective
power consumption is low; the unit is suitable for
continuous operation.
The device circuitry comprises high complexity
circuits that need to be configured to the given task
by the user. The device can be configured with
items of software, free available for downloading
from the www.cableworld.eu web site. CableWorld’s
devices and software compose a system, where
some items of software will be used with multiple
devices, and some devices need the use of multiple
items of software.
The programs run in Windows XP or Vista
environment, but CableWorld’s open system 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 that is at the
same time the instruction manual of the device can
be found in the ‘Help’ of the software. The ‘Help’
can be downloaded also separately in pdf format
from the ‘Software’ page.
Programming the MPEG-4 Encoder requires
installing the SW-4412 basic software and the SW-
4901 auxiliary software. 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 delivered
crossover cable in 100Base-T mode. However we
suggest interconnecting the device and the PC via
an Ethernet switch with straight cable.

In the first tests a simple switch can be used, but
we suggest changing to a switch suitable for
managing IGMP messages.
The MPEG-4 Encoder (as all CableWorld
products) will be delivered factory set to the
10.123.13.101 IP address. When using more than
one device in one system, you must set the devices
to different IP addresses using the SW-4901
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: CableWorld’s gigabit system
transmits the transport streams and the device
control commands in a common network,
decreasing your expenses and increasing the
potential of remote control. The transport streams
and the control commands are selected by Port
numbers. The user’s job is assigning the Port
number range to be used for transmitting the TS,
and programming this Port number range in the
device. The device control must be performed
outside the TS Port Interval. The device control may
totally be disabled by transport streams transmitted
outside their TS Port Interval.
In CableWorld’s system the gigabit transmission
is performed by FPGA circuitry, so the data rate is
not limited by the performance of internal
processors, and the gigabit data rate can be utilized
up to 100%.
4. PUTTING THE DEVICES IN OPERATION
After unpacking the device remove the
protection foil from the stainless steel cover of the
device. Connect the device to the specified mains
voltage and switch the power switch to ON. 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.eu.
Additional technical data:
All ASI inputs and outputs are separated 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 to a proper point. This
point has to be found individually in each
application.
In the CableWorld CW-4000 system 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 the users integrate our
products into their systems and undertake writing
own software for operating these products.
CableWorld assures extra technical support for
these creative users; in the CableWorld system the
instruction sets are free available for everyone, and
major users can have even the source codes of the
software.
Beyond serial products, CableWorld is ready to
deliver products for special demands and also to
implement individual ideas.
We appreciate receiving all remarks,
experiences, measuring results with our products
and we pay respect to them at our further
developments.
