Outline
XLD3304A is a cost-effective DVB-T modulator developed according to DVB-T (EN300744) standard. It has 128 IP inputs. After multiplexing and modulating process, it gives 4 DVB-T non-adjacent carriers (50MHz~960MHz) output through the RF output interface. To meet customers’ various requirements, this device is also equipped with data port for 4 MPTS output over UDP and RTP. This is very adaptable to newly generation DTV broadcasting system.
Features
* Support maximum 128 IP input(MPTS/SPTS) over UDP and RTP protocol
* Support 4 groups multiplexing +4 groups DVB-T modulating
* 4*DVB-T non-adjacent carrier output
* 4 IP (MPTS) output over UDP and RTP protocol
* Integrated multiplexing and modulating functions
* Support accurate PCR adjusting/PID Remapping/ PSI/SI rebuilding and editing
* Web-based NMS management
