SFT3306I 8in1/16in1/20in1 ISDB-T modulator ndi chipangizo chaposachedwa kwambiri cha Mux-modulating chopangidwa ndi SOFTEL. Imatembenuza mitsinje ya IP kukhala 8 (or16, kapena 20) ISDB-T yonyamula osayandikira (50MHz ~ 960MHz) yotulutsa kudzera pa mawonekedwe a RF. Chipangizochi chimadziwikanso ndi mlingo wapamwamba wophatikizika, ntchito yapamwamba komanso yotsika mtengo. Izi ndizogwirizana kwambiri ndi njira yowulutsira ya DTV yatsopano.
2. Mbali zazikulu
- Madoko a 3 GE olowetsa ndi kutulutsa IP --Version I & II
Madoko a 6 GE (4 * RJ45, 2 * SFP), data1-2 pakulowetsa kwa IP, data 3-4 ya IP output --Version III
- Max 840Mbps pakulowetsa kulikonse kwa GE
- Imathandizira kusintha kolondola kwa PCR
- Imathandizira kusefa kwa CA, kukonzanso kwa PID ndi kusintha kwa PSI/SI
- Imathandizira kukonzanso kwa 256 PIDS pa njira iliyonse
- Imathandizira kutulutsa kwa 8 IP kudzera mu Data1 & Data2 pa UDP/RTP/RTSP-Version I
Kuthandizira 16 IP kutulutsa kudzera mu Data1 & Data2 pa UDP/RTP/RTSP-Version II
Kuthandizira 20 IP kutulutsa kudzera mu Data3 & Data4 pa UDP/RTP/RTSP-Version III
- 8 (kapena 16, kapena 20) zonyamula zosagwirizana, zogwirizana ndi ISDB-Tb (ARIB STD-B31)
- Imathandizira kasamalidwe ka netiweki pa intaneti
