Outline
SNK6284 ( SNK6284A) 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. SNK6284 ( SNK6284 A) DVB-T2 modulator also supports single-PLP and multi-PLP (option) to receive T2-MI from DVB-T2 gateway through its ASI and IP port. (This function is also option.)
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-T2 STB.
