AT2800USB DVB-T Modulator With ASI & IF & RF (USB)
The modulator range of products are also available in PCI and USB versions. There are devices for DVB-T/H ( QAM, QPSK ), DVB-S ( QPSK) and DVB-C ( QAM-A/B/C and 8VSB ) modulation. All these devices have RF outputs for direct connection to STBs and IF outputs as well DVB-ASI output for monitoring the modulated Transport Stream. The TS for modulation may come from a TS file on the harddisk, from an external DVB-ASI or DVB-SPI sources. By adding an Alitronika De-modulator device a complete system for modulation, trans-modulation, multiplexing, re-multiplexing can be developed with a minimum of cost and efforts.
Targeted for Digital Video Professionals, Sophisticated End Users and OEMs
