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picture and sound, by today was superseded by the MPEG-4 compression technique.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. T his version of the equipmen t allows the transmiss ion of digital SD I
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 outp ut tra nsp or t
stream includes t he m ost imp orta nt PSI/S I tab les ( PAT, P M T, S DT, NIT), thus in s impler systems
the encoder can be applied even without using a remultiplexer. Th is e dition contains a 100 Base-T
Ethernet UDP/IP marked connector.
Structure
Features
• Digital vide o and audio input: SD/HD-SDI (with stereo embedded audio)
• Wide range of resolutions: 720x576i, 1280x720p, 1920x1080i
• System bitrate adjustable range of 1000 … 15000 kbps
• Audio bitrate adjustable between 32 and 384 kbps
• PSI inserter included with editable parameters
• Unicast / multicast UDP/IP output 100 Base-T full duplex mode ETH
• Separated management port for configuration
• Simple configuration in web browser
• Informative, wide display
• Low power consumption

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!
