ZJ3308AT 8 mu 1 ATSC Modulator
Chidule cha Zamalonda
ZJ3308AT 8 mu 1 ATSC modulator ndichinthu chatsopano chomwe chikuthandizira kulowetsa kwa IP. Ili ndi njira 8 zokulumikizira ndi njira 8 zosinthira za ATSC, ndipo imathandizira kulowetsa kwakukulu kwa 256 IP kudzera pa doko la GE. ZJ3308AT ili ndi mphamvu zotulutsa zopitilira 8 zonyamula zosakhala pafupi (50MHz ~ 960MHz) zotulutsa kudzera pa RF yotulutsa mawonekedwe. Dongosolo la chipangizochi chitha kukhala pamzere wolamulidwa ndikusinthidwa kudzera pa netiweki, yomwe ingagwiritsidwe ntchito kwambiri pakupanga maukadaulo a ATSC ndi kuyesa kwa ATSC set top box design.
Makhalidwe Abwino
● Madoko a 3 GE (max 256 IP mkati):
● Madoko olowera mbali a Data1 & Data2, max 256 IP mkati, 8 IP out Data port (yomwe ili kutsogolo kwa gulu), max 128 IP mkati
● Max 840Mbps pazolowera iliyonse
● Imathandizira kusintha kolondola kwa PCR
● Imathandizira kukonza PID ndikusintha kwa PSI / SI
● Imathandizira kukonza ma PID mpaka 180 pa njira iliyonse
● Thandizani 8 multiplexed TS pa UDP / RTP / RTSP
● Zotengera za 8 ATSC zosayandikira, zogwirizana ndi muyezo wa ATSC A / 53
● Imathandizira kulemba ma RS (208,188)
● Thandizani kasamalidwe kapaintaneti
