DMB-9580P MPEG{1}}/H.264 SD Encoding & Modulator (tag nrho-hauv-ib) yog cov khoom siv siab ceev thiab hloov tau yooj yim, sib koom ua ke Encoding, Multiplexing, scrambling thiab Modulation nrog nws cov kev ua tau zoo ntawm MPEG-2/H.264 encoding. Nws txhawb 8/12/16/24 * CVBS, 1 * tuner thiab 128 * IP inputs thiab 4 * DVB-C / T RF tso zis. Tsis tas li ntawd, nrog nws cov multiplexing module, cov kev pab cuam hauv zos tuaj yeem rov ua ntau dua rau hauv 4 * MPTS cov khoom tawm nrog cov kwj tawm sab nraud.
Lub DMB-9580P muab cov yeeb yaj kiab tsis zoo thiab txhim khu kev qha nrog cov yees duab compression siab MPEG-2/H.264 thev naus laus zis, nrog tus nqi qis qis qis kom txuag bandwidth thiab thauj ntau cov kev pab cuam hauv txhua tus neeg nqa khoom. Nws tuaj yeem siv rau IPTV system nrog TS dhau IP tso zis / tawm tswv yim xws li tsev so / tsev kho mob / zej zog system.
Nta:
Muaj hwj chim Video encoding xaiv --SD MPEG-4 AVC/H.264, MPEG-2
Advanced Audio compression --MPEG1 Layer II, AC3(2.0), kev hloov kho suab
Kev ua tau zoo--4 pawg ntawm multiplexing/scrambling/modulation output channels
Flexibility ntau tshaj --Txhawb PID remapping, raug PCR kho, PSI / SI muab tso ua ke thiab teeb tsa
Tswj los ntawm lub vev xaib UI --Kev teeb tsa yooj yim ntawm kev tswj hwm lub vev xaib
