ASI/DVB-T Transmodulator
This transmodulator as accessory for the TechniNet IP enables together with the TechniNet IP IRD cards, the modulation and feed of MPEG-signals in a cable network. The modulator card receives the DVB-transport stream via the ASI Input and modulates this into a CODFM-signal, generates this in a DVB-T conform output signal for a frequency range of 48 to 862 MHz.
The high performance transport stream modulaters enables to filter PID´s and single programmes, whereas SI/PSI tables will be fit automatically. A new NIT can be generated locally and feed into the transport stream. The operation of the rack is either local with the cable connected programmer or remote via Ethernet and the TechniNet Management software on PC.
HDTV

HDTV

HDTV stands for High Definition Television, thus for outstanding picture quality. With HDTV, pictures can be displayed in much greater detail and with much finer gradations. Contrast and contours are more precise and colours truer to their originals. Furthermore, the wide screen format on HDTV broadcasts corresponds much better to human visual perception. So it creates a more vivid impression overall.
