High Integrated MUX QAM Modulator MSM628

Txheej txheem cej luam

MSM628 yog ib tug high-density, modular thiab kev TS processor nruab nrog 16 ywj siab tuners, uas yuav ua tau los ntawm DVB-T / T2, DVB-S2 / S, DVB-C, ATSC thiab ISDB-T hom ua hauj lwm nrog ob GbE Ports. thiab Ob DVB-ASI Ports inputs. Nws yog qhov tsim nyog rau txhua qhov kev lag luam uas xav tau kev sib koom ua ke cov ntsiab lus nyob hauv video thiab muab ntau yam hauv TV hauv zos Coax Cable xa tawm ntawm Digital TV tshaj tawm cov tsev lag luam, tsev, tsev so, tsev kho mob, tsev kawm ntawv thiab tsoomfwv lub koom haum.

 

MSM628 Nruab nrog ob tus IP In/Out cov ntaub ntawv chaw nres nkoj txais tos lossis streaming ntawm MPEG raws kev thauj kwj hla UDP/RTP. Txhua qhov chaw nres nkoj ua haujlwm ntawm nws tus kheej thiab tuaj yeem teeb tsa raws li IP hauv thiab IP tawm txhawb nqa tag nrho 840 Mbit / s TS cov ntaub ntawv tus nqi thiab txog 512 MPEG cov kev pabcuam. Cov ntsiab lus tag nrho ntawm qhov chaw nres nkoj nkag tuaj yeem raug mapped pob tshab thiab Multiplex rau qhov tso zis modulated Carrier Channel nrog kev xaiv los ua PID lim lossis kev pabcuam lim.

 

MSM628 ua rau tag nrho-IP headend architecture, ua rau muaj kev hloov pauv ntau dua thiab tus nqi qis dua hauv kev pab cuam thiab kev faib khoom. Qhov no yog ib qho kev daws teeb meem zoo tshaj plaws rau ib puag ncig uas koj muaj ntau qhov huab cua Channel, MPEG-TS IP Cov Ntsiab Lus thiab siv ntau rau Medium-Scale Cable TV tus neeg teb xov tooj, cov chaw hauv tsev so, lossis txhua yam ntawm Cov Teeb Pom Kev Hloov mus rau Cable TV tshaj tawm ib puag ncig hauv kev txwv. Nyiaj txiag hnyav.Qhov chaw tsim tau tsim tshwj xeeb tshaj yog rau cov channel siab ceev tshwj xeeb rau cov chaw nyob qhov chaw sai sai, kev tswj hwm sai thiab sib xyaw yog qhov tseem ceeb. Siv nyob rau hauv qee qhov chaw ncaws pob nto moo hauv ntiaj teb, qhov no yog qhov kev daws teeb meem zoo tshaj plaws rau qhov chaw uas koj muaj ntau qhov chaw, xws li chaw ntau pob, chaw lom zem, lossis chaw tshaj tawm.

 

Cov txiaj ntsig ua lag luam

• Txhim kho Modulated Channel kev siv peev txheej
• Tus nqi ua tau zoo
• Txo tus nqi thiab kev tswj xyuas kom yooj yim
• Concurrent siab muaj rau txhua qhov kev pabcuam
• Tiag kuj tuaj yeem siv cov nqi siab tshaj plaws hauv kev siv nyiaj tsawg

 

Feature
