General description
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picture and sound, by today was superseded by the MPEG-4 compression technique.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 Teletechnika developed the new generation of its encoders, the
MPEG-4 (H.264) Encoder. This version of the equipment allows the transmission of digital SDI
with embedded audio using H.264 MPEG-4 PART10 compression. Digitalized and compressed
voice and picture is composed to Single Program Transport Stream (SPTS). The output transport
stream includes the most important PSI/SI tables (PAT, PMT, SDT, NIT), thus in simpler systems
the encoder can be applied even without using a remultiplexer. This edition contains a 100 Base-T
Ethernet UDP/IP marked connector.

Mechanical parameters, operation
The height of the encoder is 1 unit (1U) with 19’’ width and is supplied with standard
power cable.
In case of rack-mounted usage, the operator should take care of the proper airflow and
ventilation! Do not cover the case because it could cause overheating!

SDI IN: Serial Digital Interface: Formerly the SDI interface was used only for linking
professional video equipment within the studio at the transmission of
uncompressed digital video signals. Today, the SDI interface can be found at
the inputs and outputs of more and more equipment of cable television and
other fields. Its great advantage is that one single coaxial cable can be used for
transmitting the picture and sound. The standard BNC connector on the back
panel of the MPEG-4 encoder is used for connecting the SDI signal. Over
time the SDI transmission developed to a fairly wide range of standard family.
The encoder supports the following formats: SD-SDI (SMPTE 259M, 270
Mbit / s), HD-SDI (SMPTE 292M, 1.485 Gbit / s). The transmission of sound
(embedded audio) is provided in the form of additional data, according to
SMPTE 272M (SD-SDI) and SMPTE 299M (HD-SDI).
Additional information: Due to the high bitrate use high-quality, double shielded coaxial cable, and try to minimize the length of
the cable, although originally the standard guarantees hundreds of meters of transmission quality.

User manual
The equipment could be started by turning the power switch ON, located beside power
connector. After the turn on, the POWER LED starts to light in case of faultless function. After
the start the LCD informs the user about the main state of the equipment:
At first by the boot procedure in the 1st line with the ‘Teletechnika Ltd. - MPEG4 HD
ENCODER’ label. In the 2nd line are the ‘Initializing .......’ label. Please wait by the boot section
about 15-20 seconds. By successful start an ‘OK’ word will appear after the points. If we have
some problem a ‘REBOOT!’ word and the equipment reboots until the successfully boot occurs.
Then, the previously described information displayed on the display.
Settings
The settings of the equipment only could be done via the MGMT connector. If there is
only a cable between the equipment end the computer it must be a crosslink type, otherwise e.g.
with a switch or router, the type of the used cable is not important.
To operate and reach the Encoder with our PC it has to be set into the same IP address
range as the equipment. The factory IP address of the equipment is on the 10th page of LCD. The
factory IP address begins with ‘192.168.1.’ with 255.255.255.0 mask.

Web surface
The general and IP settings of the equipment can be reached via our PC’s browser. Type
the IP address into the browser’s heading and press enter.
At first an username / password window will appear. In factory settings there are not

Measure / Main parameters:
Clicking this menu item in the web browser connects to the Encoder’s 10001 control TCP port.
The process of connecting a disconnected puzzle icon and the 'Connecting ...' label is marked:
If the connection is successfully a connected puzzle and a ’Connected’ label is displayed:
If you lose the connection with the device a disconnected puzzle again a ‘Disconnected’ label is
displayed:
If you have a physical relationship exists and still get Disconnected appears, make sure that only
one browser is opened and the device is not busy on the TCP socket port, as well as to get to the
10001 port on the device. If all the conditions are now in terms of the network device port access
control and still get disconnected inscription try to reconnect it click to another menu and then
come back. Make sure that Internet Explorer is used, do not open a browser and a few sheets of
the same Encoder device.
