H518 4 IN 1 QAM(DVB-C) Modulator with Demodulator
& Re-Multiplexer and TS OVER IP |
4 IN 1 QAM(DVB-C) Modulator with
Demodulator & Re-Multiplexer and TS OVER IP BOY-H518 is the successive
of the latest version of BOY professional DVB Transmodulator. The
input TS carrier (including DVB-ASI, DVB-S2/-S/-C/-T) can be converted
to a new QAM carrier. With its built-in 5 re-multiplexer cores, the
final TS could be highly customized. The IP streaming TS port could
be configured as input or output and is independently operated. LAN
control and monitoring are achieved by TCP/IP, SNMP and HEMS*. (*
Head-end Equipment Management System, a BOY' s proprietary software)
