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picture and sound, by today was superseded by the MPEG-4 compression technique.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 decoders, the
MPEG4 (H.264) HD DECODER. The equipment allows the receiving of Single Program
Transport Stream and after decompressing forwards the video and audio content to the analog
video- a nd aud io out puts a nd digital SD I output with embedded audio using eit her M PEG-2 or
H.264 MPEG-4 PART 10 decompression. This version of the equipment contains a 100 Base-T
Ethernet (UDP/IP) 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!
