Screen Service is proud to present the third generation of digital modulators for terrestrial television transmission. Thousands have been produced thus far, demonstrating the versatility and compliance of these units with demands of modern broadcasters. The DVB standard-compliant model allows the generation of 2 and 8k COFDM signals (4k in the DVB-H) version with QPSK, 16QAM and 64QAM modulations supporting all uniform, hierarchical and non-hierarchical modes, while the model for ATSC standards are available for 8VSB modulation (16 VSB optional).

The integrated SFN adapter makes it possible to operate in isofrequency SFN), as well as to lock to a frequency reference signal (GPS receiver, optional) and network delay compensation. All models carry multiple inputs with automatic switch-over to guarantee continuous service even in the case of main signal lack. The purity of local oscillators and the linearity of RF circuits guarantee excellent MER levels at the output.

Thanks to the exclusive DUAL-MODE option, these units are able, among other things, to generate with the same hardware analogue carriers and modulations, allowing the same equipment to transmit DVB-T or PAL and ATSC or NTSC signals, thereby offering our clients matchless investment efficiency. All operating parameters may be viewed and configured through a local control panel and through LAN connection, thanks to Java technology user interface displayed through a common Web browser.
