XLD3301C QAM Modulator
Outline
The Xielide XLD3301C QAM modulator is a high performance modulator developed according to DVB-C (EN300429) standard. This unit provides a more powerful receiving ability to receive TS coming from encoder, multiplexer, DVB gateway, scrambler and etc. NDS3301C supports 2 IP (MPTS/SPTS) input and 2 carriers output.
Simultaneously, the modulator disposes the TS with RS encoding, convolution interlacing and QAM modulating. For the field scope, it can be used for Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.
Features
* Fully complying with EN300 429/ITU-T J.83A/B/C (DVB-C), GB/T170 standard
* Five constellation modes: 16QAM, 32QAM, 64QAM, 128QAM and 256QAM
* 2 channel IP input (MPTS/SPTS) over UDP
* Huge buffer memory for the burst code stream
* Intelligence null packet deleting, automatically TS filling and PCR accurate adjusting
* VCT (Virtual Channel Table) support
* Support PID filtering, re-mapping and PSI/SI update synchronously.
* Effective inputting real-time bit rate monitoring
* 2 carriers output frequency range: 30MHz~1000MHz, 1 kHz step
* LCD and keyboard operation, and Web-based NMS management
