Integrated Receiver/Decoder

Ib qho kev sib koom ua ke receiver / decoder (IRD) los yog Integrated receiver / discrambler yog ib qho cuab yeej siv hauv lub taub hau digital kom tau txais thiab txiav txim siab cov teeb liab los ntawm satellites lossis lwm qhov chaw sab nraud. IRD tau txais cov teeb liab digital, txiav txim siab nws, thiab xa nws mus rau lub hauv paus rau kev ua haujlwm ntxiv. IRD feem ntau txuas nrog lub modem, uas xa cov teeb liab decoded mus rau lub hauv paus system, qhov twg nws tau ua tiav, formatted thiab faib rau ntau txoj kev. IRD kuj tseem siv tau los encrypt cov ntaub ntawv, tso cai rau lub hauv paus system tswj kev nkag mus rau cov ntsiab lus. Tsis tas li ntawd, IRD tuaj yeem siv los tswj qhov zaus ntawm lub teeb liab, tso cai rau lub taub hau kom zoo rau kev txais tos ntawm lub teeb liab.

Dab tsi yog integrated receiver decoder siv rau?
Cov ntawv thov tseem ceeb ntawm Integrated Receiver / Decoder (IRD) yog digital TV, digital radio, IPTV, Video on Demand (VOD) thiab video streaming. Nws ua haujlwm los ntawm kev txais thiab txiav txim siab lub teeb liab tshaj tawm digital rau hauv hom uas tuaj yeem tso tawm lossis saib hauv TV lossis lwm yam khoom siv xov xwm. IRD tom qab ntawd hloov cov teeb liab digital rau hauv lub teeb liab analog uas tuaj yeem pom hauv TV. Tsis tas li ntawd, IRD tseem tuaj yeem siv los tswj kev nkag mus rau qee cov channel lossis cov kev pabcuam, thiab txiav txim siab lossis tshem tawm cov teeb liab digital.

Dab tsi yog qhov tshwj xeeb ntawm kev sib koom ua ke receiver decoder koj yuav tsum saib xyuas?
Cov ntsiab lus tseem ceeb tshaj plaws ntawm Integrated Receiver / Decoder uas cov neeg yuav khoom yuav tsum xav txog yog nws lub peev xwm txiav txim siab, tawm tswv yim / tso zis txuas, kev daws teeb meem, audio / video outputs, chaw taws teeb tswj kev sib raug zoo, duab zoo, thiab tus nqi. Lwm qhov tshwj xeeb tseem ceeb uas cov neeg yuav xav tau xav txog suav nrog qhov loj thiab qhov hnyav ntawm chav tsev, tus naj npawb ntawm cov tuners, lub peev xwm ntawm daim duab hauv daim duab, lub peev xwm kaw, thiab ntau qhov chaw tso zis (HDMI, Cov Khoom, thiab lwm yam).
Ntxiv rau qhov no, nco ntsoov ua raws li cov kauj ruam no ua ntej txiav txim siab zaum kawg:
Kauj Ruam 1: Txheeb xyuas koj cov kev xav tau. Xav txog seb hom ntsiab lus twg koj xav tau txais, thiab hom yam ntxwv twg koj xav tau koj Integrated Receiver / Decoder kom muaj.

Kauj Ruam 2: Sib piv cov yam ntxwv thiab tus nqi. Saib cov qauv sib txawv kom pom qhov zoo tshaj plaws raws li koj xav tau. Xav txog cov xov tooj ntawm cov channel, kev daws teeb meem, suab / video zoo, kev siv yooj yim, thiab tus nqi.

Kauj Ruam 3: Nyeem cov kev txheeb xyuas. Nrhiav kev tshuaj xyuas los ntawm cov neeg siv khoom uas tau yuav cov qauv qub uas koj nyiam.

Kauj Ruam 4: Nug cov lus nug. Yog tias koj muaj lus nug txog cov khoom, nug tus neeg muag khoom lossis cov chaw tsim khoom. Lawv yuav tsum tuaj yeem teb cov lus nug uas koj muaj ua ntej koj ua koj qhov kev yuav khoom.

Kauj Ruam 5: Muab koj daim ntawv xaj. Thaum koj tau pom Integrated Receiver / Decoder uas ua tau raws li koj xav tau, tso koj daim ntawv xaj. Nco ntsoov ua tib zoo mloog rau txhua txoj cai xa rov qab, yog tias koj tsis txaus siab rau koj qhov kev yuav khoom.
Dab tsi yog lwm yam khoom siv ua ke nrog kev sib koom ua ke txais / txiav txim siab hauv lub taub hau digital?
Cov khoom siv sib xws lossis cov khoom siv uas tau siv ua ke nrog Integrated Receiver / Decoder (IRD) hauv lub tshuab digital headend muaj xws li modulators, encoders, multiplexers, thiab scramblers. IRD ua haujlwm kom tau txais thiab txiav txim siab cov cim digital thiab tom qab ntawd tso tawm lawv. Lub modulator siv cov zis tawm los ntawm IRD thiab hloov kho nws mus rau cov neeg nqa khoom nthwv dej kom nws tuaj yeem kis tau. Lub encoder siv lub teeb liab modulated thiab encodes nws nyob rau hauv ib hom ntawv tshwj xeeb, xws li MPEG-2, thiaj li yuav kis tau. Lub multiplexer tso cai rau ntau lub teeb liab yuav tsum multiplexed mus rau ib lub teeb liab ntws, uas yog xa mus rau lub scrambler. Lub scrambler xyuas kom meej tias tsuas yog cov neeg siv tau tso cai tuaj yeem nkag mus rau lub teeb liab.
Dab tsi yog qhov txawv ntawm Integrated receiver / decoder thiab satellite receiver?
Qhov sib txawv tseem ceeb ntawm Integrated Receiver / Decoder (IRD) thiab satellite receiver yog hom teeb liab uas lawv tau txais. Ib qho IRD tau txais cov teeb liab los ntawm lub xov tooj cua lossis satellite, thaum lub satellite txais tau txais cov teeb liab los ntawm lub phaj satellite. Ib qho IRD feem ntau yog siv los txiav txim siab encrypted signals los ntawm cable lossis satellite chaw muab kev pab, thaum lub satellite receiver yog siv los txais cov teeb liab los ntawm satellite. Ib qho IRD feem ntau xav tau kev tso npe rau cable lossis satellite chaw muab kev pabcuam txhawm rau txiav txim siab cov teeb liab, thaum lub satellite txais tsuas yog xav tau lub phaj satellite kom tau txais cov cim.
Yuav ua li cas xaiv ntawm FTA thiab CAM integrated receiver / decoder?
Qhov sib txawv tseem ceeb ntawm FTA Integrated receiver / decoder thiab Integrated receiver / decoder nrog CAM module yog nyob rau hauv cov nqe lus ntawm tus nqi, qauv, kev ua haujlwm, thiab ntau dua.

Hais txog tus nqi, Integrated receiver / decoder nrog CAM module feem ntau kim dua FTA Integrated receiver / decoder. Qhov no yog vim CAM module suav nrog cov khoom siv kho vajtse ntxiv uas FTA Integrated receiver / decoder tsis muaj.

Hais txog cov qauv, FTA Integrated receiver / decoder muaj tus qauv yooj yim dua li Integrated receiver / decoder nrog CAM module. FTA receiver / decoder feem ntau muaj tsawg dua cov khoom, uas ua rau nws yooj yim rau nruab thiab tswj.

Hais txog kev ua haujlwm, Integrated receiver / decoder nrog CAM module muaj peev xwm ntau dua li FTA receiver / decoder. Nws muaj peev xwm tau txais thiab txiav txim siab encrypted signals, whereas FTA receiver / decoder tsuas tau txais dawb-rau-air signals.

Integrated receiver/decoder with CAM module kuj tseem muaj cov yam ntxwv ntxiv, xws li muaj peev xwm sau thiab khaws cov kev pab cuam, nkag mus rau cov kev pabcuam sib tham, thiab teeb tsa niam txiv tswj. FTA receiver/decoder tsis muaj cov yam ntxwv no.
