2 photosFUQ4665 HD-SD Encoder Modulator 4 Input Channels
The Hanxing FUQ4665 is an encoder-modulator in the FUQ4 line, built in our Guangzhou headend factory. Published specifications: Constellation QPSK, 16QAM, 64QAM; Power supply DC 12V; Video MPEG-2, MPEG-4 AVC/H.264. 18 parameters are published on this page from the model's own datasheet; quotations are factory-direct.
Built for broadcast headends, the FUQ-4665 HD-SD encoder modulator takes 4 input channels over HDMI, YPbPr and CVBS. Encoding runs MPEG-2 or MPEG-4 AVC H.264 to DVB-T-C-ATSC RF output. A USB port handles record and playback. We ship it to headend projects that need both HD and SD channels on one chassis.

Next stage in the chain
An encoder modulator puts the signal on one RF carrier at one point of the network. When that single carrier has to reach a whole town rather than a building, the next stage is a DVB-T transmitter: it takes the same transport stream and raises it to the output power the coverage plan needs.
