Overview
IRD4CI-AP 4 in 1 HD DVB-S2 IRD with 4CI Slot receives signal which complies with DVB standard from RF inputs, ASI inputs and IP inputs, and convert the signal to standard TS after demodulation and/or de-embedding; it then descrambles the TS through CAM descrambling module and output transparent TS to its 4 ASI or IP output ports.
1.Four CI interfaces which comply with EN 50221 standard to support multiple main CA
2.Support DVB-S/S2, DVB-C, DVB-T and DMBT signal demodulating
3.Support bypass for ASI, RF and IP signals
4.PCR correction
5.MPEG TS-over-IP Gigabit Ethernet input/output
6.Power failure memory recovery
7.Support four ASI input/output interface, four RF input interface, as well as Gigabit IP data interface and 100 Mbps IP data interface
8.Keyboard cooperated with LCD display to realize local controlling
9.Support SNMP-based management (subject to the specific configuration)
