The new DBT and DTT series consist of a new generation of digital television transmitters with a very high degree of integration for SFN or MFN networks according to DVB-T, DVB-H and ATSC standards. A broad range of modulators and accessories allows the configuration of these units as transmitters, transposers, gap-fillers, with or without digital echo-cancellers, and regenerative transposers. The transmitters belonging to this series are equipped with integrated SFN adapters and a highly advanced DUAL-MODE function. With this option it is possible, using the same hardware, to digitally reproduce analogue carriers and choose whether to transmit in DVB-T or PAL (ATSC or NTSC) by means of a simple locally activated push-button on the front panel, remotely using a clean contact and/or by means of a dedicated command inserted in the transport stream. Innovative firmware permits the elaboration of the signal at zero error, thanks to an internal 32 bit process.The units are equipped with interfaces for the remote control checks of the equipment through serial protocols or TCIP/IP ports. Thanks to internal Web server the user can monitor and configure the equipment using a LAN connection and a standard Web browser. | Complies with ETS 300 744 (DVB) and A53 (ATSC) specifications.All uniform, hierarchical and non-hierarchical 2k, 4k and 8k DVB-T and DVB-H modes.Integrated SFN adapter.De-jitter on input signal prior to transmission.Agile integrated up-converter.ASI and LVDS inputs.Automatic network delay compensation (SFN).GPS reference signal lock.Virtual Elastic Store.
