IP to Digital Modulator (IP to DVB-C DVB-T ISDB-T QAM Modulator)
Product Overview
The H3361F series is a cost-effective audio and video processing device newly developed by our company for digital TV front-end systems, supporting IP and ASI input to modulated output. It features 2 Gigabit input ports and 1 Gigabit output port, supports UDP/RTP protocol input, and is equipped with 6 ASI inputs. The device can be configured to provide 8/12/16/24 carrier outputs according to customer requirements.
With excellent performance and flexible configuration, the unit adopts a compact 1U chassis for easy installation and operation. A single device integrates a complete set of front-end system functions, making it ideal for various new-generation digital TV broadcasting systems. It supports DVB-C output, 8/16 MPTS/SPTS IP streams from Data 1 output, and multiplexes programs from IP and ASI sources to downstream equipment.
