FMUSER DTV4427 16-Channel IP QAM RF Modulator chishandiso chinogoneka cheCATV nhepfenyuro masisitimu.

 

Iyo ine gumi nematanhatu ekuwedzera nzira, gumi nematanhatu ekukwenya chiteshi, uye gumi nematanhatu QAM modulating chiteshi. Nerutsigiro rwekusvika ku16 IP mapipu kuburikidza ne16 GE ports uye anosvika gumi nematanhatu asina-pedyo vatakuri (16MHz ~ 512MHz) inobuda kuburikidza neRF inobuda interface, iyi modulator yakanyatsobatanidzwa, yakakwirira-kuita, uye inodhura-inoshanda.

 

Inotsigira chaiyo PCR kugadzirisa, CA kusefa, PID remapping, uye PSI/SI editing, inosvika zana nemakumi masere PIDS remapping pachiteshi. Iyo modulator inotsigirawo DVB general scrambling system (ETR180) uye Simulcrypt mitemo ETSI 289 101 uye ETSI 197 103. Inobudisa 197 isina-pedyo QAM vatakuri inoenderana neDVB-C (EN 16 300) uye ITU-T J.429 AJ. , nerutsigiro rweRS (83) encoding. Kutungamira kuri nyore newebhu-based network manejimendi, zvichiita kuti chishandiso ichi ive sarudzo yakanaka yeCATV nhepfenyuro masisitimu.
