Kev koom ua ke siab heev Txhua yam - hauv -Ib qho Digital TV Frontend Solution
Cov cuab yeej no koom ua ke tiag tiag -lub sijhawm HD encoding, kev tshaj lij digital multiplexing, thiab ntau- qauv RF modulation rau hauv ib lub platform compact, tshem tawm qhov xav tau rau cov khoom siv sib cais thiab ua kom yooj yim kawg - mus rau -kawg TV teeb liab faib architecture. Nws txhawb kev nkag mus tau yooj yim thiab sib xyaw ua ke ntawm ntau qhov chaw teeb liab, suav nrog HDMI baseband inputs, 128-channel MPTS/SPTS ntws hla UDP/IP, thiab 2 ywj siab ASI inputs. Txhua qhov chaw nkag tau (HDMI, IP, lossis ASI) tuaj yeem hloov pauv mus rau txhua qhov chaw tso zis, xa cov kev sib tw tsis sib xws rau kev tshaj tawm, kev tos txais qhua, thiab cable TV pem hauv ntej-kawg daim ntawv thov.
Kev Tshaj Tawm Tshaj Tawm Tshaj Lij Tshaj Lij Tshaj Lij & Hybrid Input Support
Tshaj li cov tub ntxhais HDMI, IP, thiab ASI inputs, lub cuab yeej muaj qhov hloov tau yooj yim rau cov xov tooj cua digital TV tuner, nrog rau kev sib raug zoo rau DVB-S/S2, DVB-}C, DVB-T/T2, ISDB{5}}T, thiab ATSC cov qauv thoob plaws satellite, cable, thiab terrestrial TV txais. Nws ua rau ib txhij hybrid input ntawm HDMI HD teeb liab thiab tuner zaus teeb liab, nrog customizable configuration schemes xws li 16-channel HDMI + 8-channel tuner (frequency point) input, zoo kawg nkaus yoog mus rau ntau yam teeb liab nkag mus rau hauv kev sib txawv deployment scenarios.
Kev nplua nuj, Configurable Full -Matrix Output Capabilities
Cov cuab yeej muab cov kev xaiv tso zis ntau ntxiv kom ua raws li cov qauv kev sib kis thoob ntiaj teb thiab qhov project- cov kev xav tau tshwj xeeb:
IP tso zis: Txhawb 127-channel SPTS tshaj UDP / RTP, ntxiv rau 1 txog 8 ywj siab MPTS tso zis rau hloov pauv IP kwj faib
ASI tso zis: Nruab nrog 2 siab ywj siab ASI tso zis interfaces rau kev poob qis baseband teeb liab kis tau tus mob
RF tso zis: Muaj ntau hom kev kho kom haum xeeb, nrog 4/8/16-channel RF cov neeg nqa khoom tso tawm tau sib xws nrog DVB-T, ATSC-T, ISDB-T / Tb, thiab DTMB terrestrial TV cov qauv, lossis 16/32-channel optimized QAM tsheb cables
* Ceeb toom tshwj xeeb rau ISDB-T hom: Thaum teeb tsa rau ISDB-T RF tso zis, tsuas yog 1-channel ASI cov tswv yim muaj; ISDB-T tso zis tsuas yog txhawb 2K kis tau tus mob hom, thiab tsis txhawb 4K lossis 8K UHD teeb liab ua.
