4 HDMI Encoder Modulator

DMB-9581E Series Ntau-Channel H.264 HD Encoder & Modulator (Tag nrho-hauv-ib)​ yog ib tug siab -qhov ceev, hloov tau yooj yim integrated ntaus ntawv uas combines encoding, multiplexing, encapsulation, thiab modulation rau 8/12/16/20 mus txog 24 HDMI inputs. Nws muab qhov zoo tshaj plaws HD encoding thiab modulation kev ua tau zoo. Ntxiv nrog rau HDMI inputs, lub cuab yeej kuj txhawb nqa ib txhij tuner tswv yim, ua kom muaj kev cuam tshuam ntawm cov teeb liab tuner nrog rau HDMI teeb liab encoding. Nws muab cov zis RF configurable hauv DVB-T/DVB-C/ATSC/ISDB-T/DTMB hom.

Encoder Modulator​ (tseem hu ua Encoder-Modulator lossisEnc Mod) yog cov khoom tshaj tawm tshaj lij uashloov cov suab / video tawm suab rau hauv kev tshaj tawm - npaj TV teeb liab.

Hauv cov ntsiab lus yooj yim, nws ua ob txoj haujlwm tseem ceeb:

Encoding (Digitizing & Compressing):

Nws yuav siv lub suab / yees duab inputs (xws li HDMI, SDI, lossis IP ntws) thiab hloov lawv mus rau hauv cov kwj tawm digital (feem ntau hauv MPEG-2, MPEG-4, H.264, lossis H.265). Qhov no ua rau lub teeb liab me me rau kev sib kis tau zoo.

Modulating (Ua kom nws tshaj tawm):

Nws yuav siv qhov compressed digital kwj thiab "modulates" nws- txhais tau tias nws tso cov ntaub ntawv mus rau ib lub xov tooj cua tshwj xeeb (RF) cov teeb liab. Qhov no tsim cov teeb liab TV txheem uas tuaj yeem nkag siab tau los ntawm TVs lossis teeb tsa- cov thawv sab saum toj

Tswv yim

Version 1: Txhawb 4, 8, 12, 16, 20, los yog 24 HDMI inputs, ntxiv rau 2 ywj siab ASI inputs thiab 128 IP (SPTS / MPTS) kwj, nrog multiplexing muaj peev xwm.

Version 2: Muaj kev xaiv HDMI + Tuner hybrid input configurations, xws li 16 HDMI + 8 Tuners lossis 8 HDMI + 16 Tuners. HDMI thiab Tuner inputs yuav tsum yog nyob rau hauv ntau ntawm 4, nrog ib tug siab tshaj plaws ua ke tag nrho ntawm 24 input channels.

Tso zis

DATA1: IP tso zis txhawb RTMP, HTTP, RTSP, HLS, thiab SRT raws tu qauv.

DATA2: IP tso zis txhawb UDP / RTP raws tu qauv; ntxiv rau 2 ywj siab ASI tso zis.

RF tso zis: Configurable rau 16/24 RF cov cab kuj nyob rau hauv DVB-T, ATSC-T, ISDB-T, Tb, los yog DTMB hom, los yog 32 RF cov cab kuj nyob rau hauv DVB-C hom.

(Ceeb Toom: ISDB-T RF tso zis yog txwv rau 1 ASI cov tswv yim thiab txhawb nqa 2K hom nkaus xwb; 4K thiab 8K tsis txaus siab.)

Nta​

Qhov zoo tshaj plaws modulation linearity thiab teeb liab zoo, nrog Modulation Error Ratio (MER) ntawm ntau dua lossis sib npaug rau 40dB.

Lub zog- tsim kom muaj txiaj ntsig zoo nrog kev ua haujlwm siab, muab Lub Sijhawm Nruab Nrab Nruab Nrab Tsis Ua Haujlwm (MTBF) ntau dua lossis sib npaug li 50,000 teev.

Ua-hauv multiplexing functionality rau integrating local sourced content with external Transport Stream (TS) los yog IP-raws li inputs.

Configuration nco yog khaws cia thaum lub hwj chim poob.

Kev tswj chaw taws teeb thiab saib xyuas nkag tau los ntawm tus qauv web browser ntawm Ethernet chaw nres nkoj.

Firmware tuaj yeem hloov kho seamlessly ntawm lub network los ntawm Ethernet interface.
