Tha FMUSER DTV4427 16-Channel IP QAM RF Modulator na inneal ioma-ghnìomhach airson siostaman craolaidh CATV.
Tha 16 seanalan ioma-fhillte, 16 seanalan sgrìobadh, agus 16 seanalan atharrachaidh QAM. Le taic airson suas ri cuir a-steach 512 IP tro phuirt 3 GE agus suas ri toradh 16 luchd-giùlan neo-ri thaobh (50MHz ~ 960MHz) tron eadar-aghaidh toraidh RF, tha am modulator seo làn-amalaichte, àrd-choileanadh, agus cosg-èifeachdach.
Bidh e a’ toirt taic do atharrachadh PCR ceart, sìoladh CA, ath-mhapadh PID, agus deasachadh PSI/SI, le suas ri 180 ath-mhapadh PIDS gach seanail. Bidh am modulator cuideachd a’ toirt taic do shiostam sgrìobadh coitcheann DVB (ETR289) agus inbhean Simulcrypt ETSI 101 197 agus ETSI 103 197. , le taic airson còdachadh RS (16). Tha riaghladh furasta leis an riaghladh lìonra stèidhichte air an lìon, a ’dèanamh an inneal seo na dheagh roghainn airson siostaman craolaidh CATV.
