Txheej txheem cej luam
DMB-9581E series multi-channel H.264/H.265 HD Encoding & Modulator (tag nrho-hauv-ib qho) yog ib qho siab- qhov ceev thiab hloov tau yooj yim, sib koom ua ke encoding 8/12/16/20 mus txog 24x, HDMI kev ua tau zoo encoding thiab modulation. Tsis tsuas yog HDMI cov tswv yim, Nws txhawb nqa tuners thiab HDMI cov tswv yim tib lub sij hawm, demodulation lub Tuners teeb liab thiab encoding lub HDMI teeb liab, tso zis RF nrog DVB-T/DVB-C/ATSC/ISDB-T/DTMB rau kev xaiv.
Lub caij no, nws xa cov yeeb yaj kiab tsis zoo thiab txhim khu kev qha nrog cov thev naus laus zis video compression, kom ua tau raws li qhov xav tau ntau ntxiv ntawm cov kev paub video zoo. Ntxiv mus, nrog nws cov multiplexing module, cov kev pab cuam hauv zos tuaj yeem rov ua dua -multiplexed nrog cov kwj tawm sab nraud. DMB-9581E series tuaj yeem siv rau IPTV system nrog TS dhau IP tso zis / tawm tswv yim. Cov cuab yeej tseem txhawb nqa cov kev pab cuam los ntawm HD STB, HD lub koob yees duab lossis playout server, PC thiab lwm yam video sib txawv.
Nta:
Kev them nyiaj yug modulation modules DVB-T, DVB-C, ATSC-T, DVB-S, ISDB-T/Tb thiab DTMB hloov tau los ntawm lub vev xaib
