Cas tus RF modulator yog thiab vim li cas koj xav tau ib qho
DVD yog ib yam khoom siv hluav taws xob hauv keeb kwm. Nws tau txais kev pabcuam raws li qhov kev lees txais ntawm kev ua yeeb yam hauv tsev, kev txhawb kev muag khoom ntawm TVs, surround suab receivers, home theatre speaker systems, thiab tseem khoov txoj kev rau Blu-txoj kab , uas, tig, coj mus rau qhov kev taw qhia txog Ultra HD Blu-txoj sab ci .
DVD Players thiab Laus Analog TVs
Txawm hais tias DVD players raug tsim los siv rau ntau hom setups, thiab nyob ntawm ntau hom thiab qauv muab ntau yam yees duab (Compass, s-video, tivthaiv, HDMI) thiab suab (analog, digital optical / coaxial) outputs , manufacturers tsis xav txog qhov kev thov rau cov players kom tseem muaj peev xwm txuas mus rau ib tus qauv kab lossis cov xov tooj tawm tswv yim ntawm cov laus dua analog TV uas tej zaum yuav tsis muaj suab / yees duab ntxiv.
Tsis txhob rov qab mus rau ib lub TV mus rau ib lub tshuab Analog Los ntawm VCR
Muaj ntau tus neeg tau txais kev pab cuam txuas lawv cov DVD player rau ib lub VCR thiab tom qab ntawd ces siv VCR kom dhau lub teeb liab rau lub TV analog, tiam sis tau ntsib cov duab zoo heev thiab cov duab ruaj khov. Yog vim li cas ib tus neeg ua DVD yuav tsis txuas nrog lub TV hauv no zam yog cov DVDs tau encoded nrog anti-luam tshuab uas cuam tshuam nrog VCR tus circuitry, tiv thaiv cov neeg siv los ntawm kev siv lub VCR ua "conduit" rau dhau cov ntawv tshaj tawm DVD rau TV . Cov ntaub ntawv siv tshuab luam tawm kuj yog vim li cas koj thiaj li tsis tuaj yeem ua ib daim ntawv luam ntawm DVD mus rau VHS daim kab xev los yog lwm yam DVD tau zoo.
Yuav ua li cas koj tuaj yeem txuas ib DVD player rau koj lub TV, yog tias koj lub TV tsis muaj hom AV nkag mus nrog cov DVD player? Secondly, koj tuaj yeem txuas tau koj cov VCR thiab DVD player koj lub TV tib lub sij hawm yog tias koj lub TV tsuas muaj ib lub xov tooj cua lossis kav hlau txais xov?
RF Modulator kua
Cov lus teb rau cov lus nug saum toj no yog lub thawv me me uas tau nyob ib ncig ntawm lub xyoo hu ua "RF Modulator" (Xov tooj Frequency Modulator). Kev ua haujlwm ntawm RF modulator yog qhov yooj yim. RF modulator converts tus yees duab (thiab / lossis suab) ntawm tus neeg ua si DVD (lossis camcorder lossis video game) rau hauv ib txoj kab 3/4 teeb uas yog sib txuas nrog lub TV cable lossis kav hlau txais xov.
Muaj ntau RF modulators muaj, tab sis tag nrho cov kev ua nyob rau hauv ib tug zoo li zam. Lub ntsiab feature ntawm RF modulator uas ua rau nws zoo kawg nkaus rau siv nrog DVD yog lub peev xwm rau nws los txais cov txheej txheem suab / video tawm ntawm ib tug DVD neeg ua si thiab cov lus siv cable (txawm dhau los ntawm ib lub VCR) ib txhij.
Qhov Teem Txog Ib qho RF modulator yog Fairly Straightforward
- Ua ntej: Cia li muab koj lub xov tooj cua / VCR tso rau hauv nws lub xov tooj kev txuas ntawm RF modulator thiab cov neeg ua si DVD rau hauv RF modulator tus AV txuas .
- Thib Ob: Txuas tus qauv kab xov ntawm tus qauv modulator rau koj lub TV.
- Qhov thib peb: Xaiv qhov kev khiav dej num 3 lossis 4 tso rau sab nraum qab ntawm RF modulator.
- Qhov thib plaub: Tig lub TV rau thiab tus RF modulator yuav txais koj cov khoom siv cable rau TV. Thaum koj xav saib koj cov neeg ua si DVD, cia li muab lub TV tso rau hauv cov channel 3 lossis 4, tig lub DVD thiab RF modulator mam li txheeb xyuas cov DVD player thiab yuav tso koj cov yeeb yaj duab.
Txawm hais tias muaj cov menyuam yaus sib txawv ntawm ntau hom thiab cov qauv ntawm cov qauv Modules hauv RF Module no yeej ua raws li tau teev tseg saum no .
Ntxiv rau cov DVD players, koj tuaj yeem siv tau RF modulator los txuas rau lwm qhov video los pab rau cov laus hauv TV uas tsis muaj AV nkag, xws li DVD recorders, game consoles, streamers, thiab camcorders, ntev li ntev tau muaj kev sib txuas AV txheem. RF modulators tsis ua haujlwm nrog tivthaiv video lossis HDMI txuas.
Kev Xav Ntxiv
Yog hais tias koj tsis muaj lub tso suab , suab bar , los yog tsev ua yeeb yam hauv tsev , koj tuaj yeem nqes tau cov DVD player hauv analog lub tso suab tawm mus rau RF modulator thiab.
Obviously, koj yuav tsis tau txais cov txiaj ntsig ntawm ib puag ncig lub suab, tab sis koj yuav hnov lub suab los ntawm TV tus neeg hais lus. Tsis tas li ntawd, koj yuav tsis tau tag nrho cov txiaj ntsim ntawm daim duab zoo nkauj DVD raws li qhov kev hloov los ntawm video mus rau RF (cable) poob kho qhov kev daws teeb meem. Txawm li cas los xij, thaum koj hloov ntawm koj lub VCR thiab DVD koj yuav pom qhov zoo ntawm cov duab DVD yog qhov tseem ceeb tshaj txhua yam koj tau saib hauv koj lub TV analog.
Tsis tas li ntawd, koj tsis tas yuav siv tus RF modulator mus txuas ib lub DVD player rau hnub HD thiab Ultra HD TVs raws li lawv muab ob qho tib si analog (Compass, Component) thiab HDMI tswv yim xaiv rau txuas cov DVD player uas tsis muaj kev sib txuas ntawm cov HDMI. Qhov kev sib txuas tsuas yog qhov uas tau muab tshem tawm hauv cov TV tshiab yog S-video tawm tswv yim .
Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum tau hais tias, ntawm qee qhov chaw, tag nrho cov kev sib txuas lus analog yuav raug tshem tawm ntawm Ultra HD TVs ntawm qee kis. Tsab ntawv tshab no yuav muab kho kom muaj kev cuam tshuam cov kev hloov uas tau ua tiav.
