DVB-S2 to DVB-T DVB-T2 Modulator for wireless Digital TV headend system broadcasting
HDQ-5041B DVB-S2 to DVB-T DVB-T2 Modulator for wireless Terrestrial TV broadcasting system
HDQ-5041 DVB-T2 modulator is our new product developed complying with the DVB-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 could be upgrade and control through network system; it is widely used in setting up in digital broadcasting network, and provide good signals for scientific laboratory and DVB-T2 STBs.
