Izi IP kuti DVB-T modulator ndi zonse-mu-mmodzi chipangizo opangidwa ndi ife. Ili ndi mayendedwe 8 ochulukitsa ndi ma 8 DVB-T modulating, ndipo imathandizira kulowetsa kwa 1024 IP kudzera pa doko la GE ndi zonyamula 8 zosayandikana (50MHz ~ 960MHz) kudzera pa mawonekedwe a RF. Chipangizochi chimadziwikanso ndi mlingo wapamwamba wophatikizika, ntchito yapamwamba komanso yotsika mtengo. Izi ndizogwirizana kwambiri ndi makina owulutsira atsopano a DTV.
2. Mbali zazikulu
- Kulowetsa kwa 2 GE, mawonekedwe a SFP
- Imathandizira mpaka mayendedwe 1024 TS pa UDP/RTP, unicast ndi ma multicast, IGMP v2\v3
- Max 840Mbps pakulowetsa kulikonse kwa GE
- Imathandizira kusintha kolondola kwa PCR
- Imathandizira kukonzanso kwa PID ndi kusintha kwa PSI/SI
- Imathandizira mpaka 180 PIDS kukonzanso njira iliyonse
- Imathandizira ma TS 8 ochulukitsa kuposa UDP/RTP/RTSP
- 8 DVB-T zonyamula zosagwirizana nazo, zogwirizana ndi ETSI EN300 744 muyezo
- Imathandizira ma encoding a RS (204,188).
- Imathandizira kasamalidwe ka netiweki pa intaneti
