BM8552 Dual ISDB-Tb Modulator


Symbol BM8552 IP to ISDB-Tb modulator is a high performance modulator developed according to ISDB-Tb (ARIB STD-B31) standard. It provides a more powerful receiving ability to simultaneously process 4 IP streams inputting from other IP devices in the head end. It outputs digital RF after multiplexing process. For management and operation, this device supports local and remote control through a web-based NMS system.
