Integrated Receiver/Decoder

Integrated receiver/decoder (IRD) kapena Integrated receiver/discrambler ndi chipangizo chomwe chimagwiritsidwa ntchito pamutu wamutu wa digito kulandira ndikuzindikira ma siginecha a digito kuchokera ku satellite kapena magwero ena akunja. IRD imalandira chizindikiro cha digito, kuisintha, ndikuipereka kumutu wamutu kuti ipitirire. IRD nthawi zambiri imalumikizidwa ndi modem, yomwe imatumiza chizindikiro chojambulidwa kumutu wamutu, komwe umakonzedwa, kusinthidwa ndikugawidwa kumayendedwe angapo. IRD itha kugwiritsidwanso ntchito kubisa zomwe zili, kulola kuti mutu wamutu uzitha kuwongolera zomwe zili. Kuphatikiza apo, IRD ingagwiritsidwe ntchito kuwongolera kuchuluka kwa chizindikiro, kulola kuti mutu wamutu ukwaniritse bwino kulandila chizindikiro.

Kodi Integrated receiver decoder imagwiritsidwa ntchito chiyani?
Zomwe zimagwiritsidwa ntchito kwambiri ndi Integrated Receiver/Decoder (IRD) ndi wailesi yakanema ya digito, wailesi ya digito, IPTV, Video on Demand (VOD) komanso kusewerera makanema. Zimagwira ntchito polandira ndi kuyika chizindikiro chowulutsa cha digito kukhala mawonekedwe omwe amatha kuwonetsedwa kapena kuwonedwa pa kanema wawayilesi kapena chipangizo china chilichonse. Kenako IRD imatembenuza chizindikiro cha digito kukhala chizindikiro cha analogi chomwe chimatha kuwonedwa pa wailesi yakanema. Kuphatikiza apo, IRD itha kugwiritsidwanso ntchito kuwongolera mwayi wofikira kumayendedwe kapena mautumiki ena, ndikuchotsa kapena kutsitsa chizindikiro cha digito.
Kodi maubwino a intergrated receiver/decoder kuposa ena ndi ati?
1. Ma IRD ali ndi chitetezo chapamwamba kwambiri kuposa olandila ena, kuwapangitsa kukhala otetezeka kwambiri.
2. Ma IRD amatha kulandira zizindikiro za digito kuchokera kuzinthu zambiri, monga satellite, chingwe, ndi televizioni yapadziko lapansi.
3. Ma IRD ali ndi mphamvu zowonjezera mphamvu, chifukwa amagwiritsa ntchito mphamvu zochepa kuposa olandira ena.
4. Ma IRD amafunikira kusamalidwa pang'ono, chifukwa safunikira kukonzedwa pamanja.
5. Ma IRD amapereka khalidwe lapamwamba komanso kumveka bwino kwa audio ndi kanema kusiyana ndi olandila ena.
6. Ma IRD ndi osavuta kukhazikitsa ndikukonzekera.
7. Ma IRD amalola kuti pakhale kusintha kwadongosolo ndi zoikamo.
8. Ma IRD amagwirizana ndi zida zingapo, monga ma TV, makompyuta, ndi zida zam'manja.
9. Ma IRD amapereka zosankha zingapo zotulutsa, monga HDMI, chigawo, ndi gulu.
10. Ma IRD amapereka zinthu zambiri ndi mautumiki, kuphatikizapo Kulamulira kwa Makolo, Mawu Otsekedwa, ndi Video On Demand.
Chifukwa chiyani IRD (intergrated receiver decoder) ndiyofunikira?
Integrated receiver/decoder (IRD) ndizofunikira chifukwa zimakulolani kuti muzindikire ma siginecha a digito ndikuwalandira m'matanthauzidwe apamwamba. Ma IRD amatha kulandira ma satellite ndi zingwe zama digito, zomwe zimakulolani kuti mupeze mapulogalamu osiyanasiyana a digito. Iwo amabweranso ndi zinthu monga chithunzi-mu-chithunzi ndi digito kanema zojambulira, kuti zikhale zosavuta kuonera ndi kujambula ziwonetsero.
Momwe mungasankhire Integrated receiver/decoder (IRD) malinga ndi ntchito?
1. Digital TV: Yang'anani Integrated Receiver/Decoder (IRD) yokhala ndi zinthu monga luso lotha kuzindikira ma siginecha a kanema wa digito, kuthandizira ma encoding a MPEG4, ndi mavidiyo osiyanasiyana ogwirizana.

2. IPTV: Yang'anani IRD yokhala ndi zinthu monga chithandizo cha IPTV, kuwulutsa kwa ma multicast, ndi kugwirizana ndi ma protocol ambiri a IPTV.

3. Cable TV: Yang'anani IRD yokhala ndi zinthu monga kuthandizira miyezo ya TV ya chingwe, kugwirizanitsa ndi opereka ma TV osiyanasiyana, komanso kutha kuzindikira zizindikiro za analogi.

4. Satellite TV: Yang'anani IRD yokhala ndi zinthu monga luso lotha kuzindikira zizindikiro za mavidiyo a digito, kuthandizira machitidwe ambiri a satana, ndi kugwirizana ndi opereka TV osiyanasiyana a satana.

5. TV Yapadziko Lapansi: Yang'anani IRD yokhala ndi zinthu monga kuthandizira miyezo yambiri yapadziko lapansi, yogwirizana ndi opereka TV osiyanasiyana padziko lapansi, komanso kutha kuzindikira zizindikiro za analogi.
Kodi ma decoder ophatikizika olandila omwe muyenera kuwasamalira ndi ati?
Zofunikira kwambiri za Integrated Receiver/Decoder zomwe ogula akuyenera kuziganizira ndi kuthekera kwake kosinthira, zolumikizira zolowetsa/zotulutsa, kukonza, zotulutsa zomvera/kanema, kuyenderana kwakutali, mtundu wazithunzi, ndi mtengo. Zina zofunika zomwe ogula angafune kuziganizira ndi monga kukula ndi kulemera kwa chipangizocho, kuchuluka kwa ma tuner, kuthekera kwazithunzi pazithunzi, kujambula, ndi madoko osiyanasiyana otulutsa (HDMI, Component, etc.).
Kupatula izi, nthawi zonse tsatirani izi musanapange zisankho zomaliza:
Gawo 1: Dziwani zosowa zanu. Ganizirani za mtundu wazinthu zomwe mukufuna kulandira, ndi mtundu wanji wazinthu zomwe mukufuna kuti Integrated Receiver/Decoder yanu ikhale nayo.

Gawo 2: Fananizani mawonekedwe ndi mitengo. Yang'anani pamitundu yosiyanasiyana kuti mupeze yomwe ikukwaniritsa zosowa zanu. Ganizirani kuchuluka kwa tchanelo, kusamvana, mtundu wamawu / makanema, kugwiritsa ntchito mosavuta, komanso mtengo wake.

Gawo 3: Werengani ndemanga. Yang'anani ndemanga kuchokera kwa makasitomala omwe agula chitsanzo chomwecho chomwe mukuchifuna. Izi zidzakuthandizani kumvetsetsa bwino za mankhwala ndi momwe zimakhalira pazochitika zenizeni.

4: Funsani mafunso. Ngati muli ndi mafunso okhudza malonda, funsani wogulitsa kapena wopanga. Ayenera kuyankha mafunso aliwonse omwe muli nawo musanagule.

Gawo 5: Ikani oda yanu. Mukapeza Integrated Receiver/Decoder yomwe ikukwaniritsa zosowa zanu, ikani oda yanu. Onetsetsani kuti mumvera malamulo aliwonse obwezera, ngati simukukhutira ndi kugula kwanu.
Ndi zida zina ziti zomwe zimagwiritsidwa ntchito limodzi ndi cholandirira chophatikizika / decoder mu digito yamutu wamutu?
Zida kapena zida zofananira zomwe zimagwiritsidwa ntchito molumikizana ndi Integrated Receiver/Decoder (IRD) pamutu wamutu wa digito zimaphatikizapo ma modulators, encoder, multiplexers, ndi scramblers. IRD imagwira ntchito kuti ilandire ndikuzindikira ma sign a digito kenako ndikutulutsa. The modulator imatenga zotuluka kuchokera ku IRD ndikuzisinthira ku mafunde onyamula kuti zitha kupatsirana. Encoder imatenga chizindikiro chosinthidwa ndikuchiyika mumtundu wina, monga MPEG-2, kuti ifalitse. Multiplexer imalola ma signature angapo kuti achulukitsidwe pamtsinje umodzi wokha, womwe umatumizidwa kwa scrambler. The scrambler imawonetsetsa kuti ogwiritsa ntchito ovomerezeka okha ndi omwe angathe kupeza chizindikirocho.
Kodi pali kusiyana kotani pakati pa Integrated receiver/decoder ndi satelliete receiver?
Kusiyana kwakukulu pakati pa Integrated Receiver/Decoder (IRD) ndi cholandila satana ndi mtundu wa siginecha yomwe amalandila. IRD imalandira zidziwitso kuchokera ku chingwe kapena satelayiti wothandizira, pomwe wolandila satelayiti amalandira zidziwitso kuchokera ku dish ya satana. IRD nthawi zambiri imagwiritsidwa ntchito pozindikira ma siginecha obisika kuchokera ku chingwe kapena satelayiti wopereka, pomwe cholandila satana chimagwiritsidwa ntchito kulandira ma siginecha kuchokera ku satelayiti. IRD nthawi zambiri imafuna kulembetsa ku chingwe kapena satelayiti kuti izindikire ma sigino, pomwe wolandila satilaiti amangofunika mbale ya satana kuti alandire ma sigino.
Momwe mungasankhire pakati pa FTA ndi CAM Integrated receiver/decoder?
Kusiyana kwakukulu pakati pa FTA Integrated receiver/decoder ndi Integrated receiver/decoder with CAM module is in terms of mitengo, kapangidwe, ntchito, ndi zina.

Pankhani yamitengo, Integrated receiver/decoder yokhala ndi CAM module nthawi zambiri imakhala yokwera mtengo kuposa FTA Integrated receiver/decoder. Izi ndichifukwa choti gawo la CAM limaphatikizapo zigawo zina za hardware zomwe FTA Integrated receiver/decoder ilibe.

Pankhani yamapangidwe, FTA Integrated receiver/decoder ili ndi mapangidwe osavuta kuposa Integrated receiver/decoder with CAM module. The FTA receiver/decoder nthawi zambiri imakhala ndi zigawo zochepa, zomwe zimapangitsa kuti zikhale zosavuta kukhazikitsa ndi kukonza.

Pankhani ya ntchito, Integrated receiver/decoder with CAM module ili ndi mphamvu zambiri kuposa FTA receiver/decoder. Imatha kulandira ndikusintha ma siginecha obisidwa, pomwe wolandila/decoder wa FTA amatha kulandira ma siginecha aulere kupita ku mpweya.

The Integrated receiver/decoder with CAM module imakhalanso ndi zina zowonjezera, monga kutha kujambula ndi kusunga mapulogalamu, kupeza mautumiki ogwirizanitsa, ndi kukhazikitsa maulamuliro a makolo. FTA wolandila/decoder alibe izi.
