PROMAX, a reference in all sectors

PROMAX has developed a significant portfolio of products, thanks to a powerful and constant effort on R & D. The strategy to remain at the technological forefront and a relentless commitment to quality has allowed deploying many of our equipment and technology solutions in areas that we never would have imagined. It will be more than likely to find us in other new and unknow areas. For example, if during your holidays you have enjoyed a cruise, do not be surprised that PROMAX was accompanying you.

Re-emitters in iso-frequency mode

When a re-emitter operates in iso-frequency mode, the DTT signals are broadcasted on the same frequencies that are received. In this type of configuration is essential to avoid the coupling between the transmitting and the receiving antenna. The lack of isolation between antennas causes that the receiving antenna receives the broadcasted signal.

Digital To TV brings digital television to Prades

In the process for replacing analogue for digital television, due to its location, the town of Prades (Oriental Pyrenees, France) will be out of official coverage. Thanks to PROMAX Digital To TV (DTTV) headend, it has been possible to establish a technical solution that guarantees the continuity of reception to the residents.

Digital cable TV? This is easy!

DVB-S is the standard for digital satellite TV. DVB-T - for digital terrestrial TV. And DVB-C – for digital cable TV. So if you want to create the cable network to provide digital TV to a number of end users you need to equip all of them with DVB-C set-top-boxes. You will also need the DVB-C headend. But is this the most cost effective way? The experts from PROMAX say: no, you can make it simpler and cheaper!

Digital terrestrial distribution for local television TLP

Local television TLP (Local TV de Provence) has successfully made the transition from analogue distribution to digital distribution. The field measurements have confirmed the quality of the modulators of the PROMAX Digital To TV (DTTV) headend.

68 satellite channels trans-modulated to COFDM in Alpe d’Huez (France)

Thanks to the installation of two PROMAX Digital To TV (DTTV) head-ends, now the residential community Maeva “les Mélezes" located in Alpe d’Huez (France) can now offer 68 digital channels from the satellites EUTELSAT Hot Bird 13°E and Atlantic Bird 5°W. The channels are injected into the coaxial network of the community, by using the COFDM digital modulation. By this way, in the apartments the flat-screen TVs with integrated DTT tuner can receive directly the channels.

Demistifying spectrogram

The Spectrogram is a graphic that shows frequency in the vertical axis and time in the horizontal axis. Spectrogram is one of the many unique functions developed by PROMAX that help to identify difficult to find problems in TV distribution systems.

Digital To TV: HDTV DVB-S2 receiver for your Cable TV system

Adding HDTV channels to your Cable TV network using DT-302 is easy and cost-effective. Most of the HDTV content available nowadays is coming from satellite. Because of the higher bit rate of the high definition TV programmes this type of services are normally allocated in satellite transponders using 8PSK modulation (DVB-S2).
