Isamukeli digital TV, umsakazo kanye ikhebula

kusakata ngetinombolo kubahlali namuhla yakhiwa izinhlelo eziyinkimbinkimbi ukuthi ukuhlanganisa uhlu lamadivayisi, ngamunye lesiniketwe imisebenzi ethize. Receiver TV digital kungokwalabo esigabeni amadivayisi ezinjalo. It yenzelwe ethola futhi uvusa amasignali zazo kamuva adluliselwa idivayisi ihumusha. Lokhu kungaba qapha ikhompyutha noma ithelevishini.

incazelo

Kudivayisi ngokuhambisana imingcele eshiwo oguqula amasignali samukelwe futhi uhumusha ukuba isihenqo idivayisi digital, kanjalo umsebenzisi ezwa izinga umsindo futhi ubona umfanekiso ephelele ngaphandle ukuhlanekezela. uxhumano Ofanele owamukelayo oluthinta ngqo izinga lomsebenzi, futhi idivayisi kungenziwa ixhumeke ethereal, TV digital, inethiwekhi ikhompyutha, i-antenna noma ikhebula ye-TV.

Izici

Kalula uxhumano kunciphisa amathuba ukuphazamiseka enkonzweni. Udinga ukusebenzisa izakhi njengoba ambalwa yokuxhuma ngangokunokwenzeka ukuvumela ukucushwa lula. Lapho uthenga wiring akufanele ukhethe ezishibhile ongakhetha yekhwalithi ephansi yokuxhuma esibulalayo futhi ukuguqulela amadivayisi, ngaleyo ndlela-ke akufanele kube isikhathi eside kakhulu. compounds iDemo inciphise ukuhlanekezela. Lapho ixhunywe unit uhlelo, kuyinto efiselekayo ukuthi kungaba zisuswe ngaphandle kwezinkinga kusukela yokubeka ukuqinisekisa uxhumano.

Bamukela Ngokwazisa ngoba eliwumhlaba ithelevishini digital ifakwe RF-modulators, xhuma ezifanele ithelevishini ikhebula okokufaka lukamakhalekhukhwini. Kulesi mkhosi wenziwa ngokuhambisana ukuvama omunye iziteshi ukusakaza. A inqubo efanayo ingase isetshenziselwe ingxenye eyinhloko isampuli namathelevishini ubudala ifakwe eyodwa kuphela-antenna port.

imisebenzi

Ngu isinqumo kahle izinga umfanekiso idivayisi kuncike injabulo wokubuka. Okokuqala, ake uya esitolo bese uqhathanisa izici eziyinhloko models ezahlukene abakhiqizi eziningana. Kudingeka nokuba unqume ngesabelomali kungenzeka futhi unake okukhethekile nemingcele lobuchwepheshe.

Amandla kuyakhethwa ngokuhambisana nemigomo ekhona nemibandela. Isamukeli ithelevishini digital amandla phakathi Watts 60 isiteshi efanelekayo amafulethi ngalinye, futhi ngasese efiselekayo baqashe imishini nge nesikhundla esithe xaxa. Ukuqokwa kumelwe futhi kukhethwe kusengaphambili, khona ongakhetha ezihlukahlukene, ngokwesibonelo, i-isiqophi semithombo 7.1, 6.1 no 5.1, kodwa owokuqala babo namuhla akuyona atholwe ukusatshalaliswa okwanele.

Uhlelo lokukhethwa kuyadingeka ukwakhela izidingo ezikhona, bekuyoba sigweme isimo lapho idivayisi akanawo ukusebenza okudingekayo. Uma asikho isidingo ukulalela izingoma amabhayisikobho kufanele sinake iyunithi 5.1, it has a aphansi kuqhathaniswa nezinye izinketho.

A umamukeli ukuthola kwaphakathi ontengo yakhe yayinqunyiwe futhi umsindo wekhwalithi ephezulu ithelevishini decoders digital Kufanele ube ifomu elandelayo: DTS, Dolby Digital futhi Dolby Pro Logic.

Kuyaphawuleka ukuthi abanye owaziwa multi-abenzi yini zingaba tuners best ngenkathi brand engathandwa ungathola amadivayisi eliphezulu.

Indlela ukukhetha

Bamukela Ngokwazisa ngoba digital ithelevishini eliwumhlaba zihlukaniswe izinhlobo ezintathu, bonke babo bayithusi efanelekayo izinhlobo ezahlukene abasebenzisi. Ngamunye zilwane Amaqhawe alo. Into yokuqala ukunquma indawo ye-Sombhalo, futhi incazelo ongakhetha ukukhetha ofanele kakhulu. Thina Ingakhawulela umamukeli kwesabelomali uma ubuka iziteshi ifomathi evamile, futhi akukho Imali nyangazonke. A hardware obusebenzayo kudingeka okwengeziwe uma ubuka iziteshi kwencazelo high usebenzisa i-HDMI esibonakalayo futhi ukuxhuma kwi-Inthanethi.

ongakhetha ukonga

Ibhajethi iyunithi yazuza okwandile hhayi kuphela ngenxa yezindleko ongaphakeme, kodwa futhi operation elula, okuyinto ebaluleke ikakhulu asebekhulile. Inhloso eyinhloko ukubheka izinhlelo, izici esengeziwe ulahlekile. Ungabuka iziteshi ngiyocasha uma usebenzisa isofthiwe efanele. Phakathi nemiphumela ethile engathandeki kuyafaneleka isidingo ukulungiswa ehlelekile, kusukela ukuvama abasakazi ezithile kuyahlukahluka ngonyaka.

Isilinganiso isigaba intengo

Kukhona tuners abaningi kulesi sigaba, banalo okusezingeni eliphezulu umbono iziteshi irekhodi. Zingasetshenziswa nge inqubo okuyinto kosayizi isihenqo 42 amayintshi ngo enezela a-HDMI esibonakalayo.
