Overview
DMB-2100 DVB-T/T2 modulator is our new product developed complying with the DVB-T/T2 standard. With its advanced modulating technology, this modulator can effectively make use of the ground spectrum resources and make it possible to provide reliable signals for fixed, mobile and portable devices. Compared with DVB-T, the channel capacity is increased by 30% under the similar carrier to noise ratio (CNR) threshold. Moreover, this device can be upgraded and controlled through network system, which allows it to be widely used in setting up digital broadcasting network and provide good signals for scientific laboratory and DVB-T/T2 STB.
Features:
Powerful Video modulation- Fully complying with EN302 755 and EN300 744 standard for DVB-T/T2
Advanced Audio compression-- Support PID bypass and pass-through (option)
Highly Compact High-Integrate--2*IP input over UDP protocol, DVB-T/T2 RF out in one device,10MHz input/loop out, 1PPS input/loop out
Maximum Flexibility--Supports non-linear digital pre-distortion (DPD) ,Constant temperature crystal oscillator, as high as 0.1ppm stability
Managed through web UI -- Convenient setting via web management
