TV esikhundleni umengameli - Yinganekwane Noma Yiqiniso?

Abantu abaningi ujwayelene isimo lapho lokho izolo kwabonakala endabeni eqanjiwe kweqiniso, namuhla ngokoqobo kwansuku zonke. Manje ezitolo ezithengisa imishini computer, lenqwaba LCD Abaqaphi ukunikela yonke ukunambitheka kanye isabelomali - kusukela elula-matrix TN; MV okuthuthukile; IPS ethandwa nokunye. Ukukhethwa onobuhle qapha ephansi ekupheleni can ngisho
umuntu amasentshana zezimali isilinganiso. Kodwa eminyakeni engu-20 edlule kwakuhlukile ngempela - abanikazi ikhompyutha ngokuvamile kwadingeka ukuthola indlela ukusebenzisa i-TV yakho njengoba umengameli. Phela, intengo ejwayelekile ye-VGA ngabaqaphi kwaba "eqolo" futhi izinga isithombe ukuboniswa CGA ezivamile, washiya okuningi okufanele oyifunayo. Nokho, isinqumo - kwadingeka kuphela ukuxhuma TV njengoba umengameli. Ukuze wenze lokhu, ungacela umngani yokuqoqa electronics wesifunda elula, ukuxuba amasignali RGB endaweni eyodwa, okungase usebenze logic TV. Futhi uhlelo kwakuwukunciphisa imvamisa mpo 50 Hz okujwayelekile (usebenzisa uhlelo umhlali). Okunye ithuba - ukuthenga ihluzo ikhadi ukufinyelela i-TV Out. Kwanele nje ukuxhuma isixhumi ikhadi kanye okokufaka kwevidiyo ye-TV. Nokho, lawa makhadi isiqophi ayembalwa futhi nibaluleke okuningi.

Okwamanje, kunezinhlobo eziningi onobuhle akubizi ihluzo amakhadi, okuyinto
i eyengeziwe isixhumi Tv ukuphuma, ikuvumela ukuthi usebenzise i-TV njengoba umengameli. chip Special (elifana nalelo isethi izingcweti kokubonisa izithombe CGA VGA Abaqaphi) yakha i isiginali ye-analog ukuthi "uyayiqonda" TV.

Ukuze uxhume ku-TV setha esikhundleni umengameli, uzodinga:

- ikhebula kuyinto uhlobo lesifanele;

- ikhadi ihluzo nge okukhiphayo elihambisana umshayeli kanye esekela ithelevishini okukhiphayo.

Umklamo izixhumi amakhadi zingahluka, ngakho ngaphambi uya phezu ikhebula, kubalulekile ukuba sihlole uhlobo isixhumi.

Omunye ezivamile - kungcono RCA, kangcono eyaziwa ngokuthi i- "Tulip". Le entry ivuliwe wonke TV, intambo kanye lula ukuthola. I yokuntula, mhlawumbe, kumelwe kuthiwe zibangelwa yini kakhulu eliphezulu isithombe.

Uhlobo esilandelayo isixhumi - nxazonke, ezine. It ngokuthi SVHS. Ikhwalithi yesithombe lingaphezulu kakhulu kunaleyo yangaphambili, kusukela isignali ungafakiwe, futhi idluliselwe eceleni: umbala nge ukukhanya kanye "phansi" ehlukile kuwo wonke umuntu. By endleleni, uma kungekho isixhumi TV, ungakwazi ukuthenga i-adaptha.

Manje akusona bungavami isixhumi eziyisikhombisa pin. Lanezela amasignali esiyinhlanganisela, nezokugcina, owesikhombisa, kuyinto eziphindaphindekayo.

Uxhumano iyadingeka uma ikhompyutha yakho ivaliwe. Ngemva kwalokho, umshayeli isiqophi ikhadi, udinga kusebenze ukuthola TV, kabusha ikhompyutha yakho bese wenza kusebenze imodi oyifunayo. Kulokhu, kungase kudingeke ukuba ushintshe imithombo ku-TV (uma inani okokufaka, bekuyoba Udinga ukucacisa umthombo ezikude isignali oyifunayo).

Ngezinye izikhathi kudingeka wenze i-TV kusukela qapha. Manje ukuze usingathe lolu daba kunezindlela eziningana yilezi:

- ukuthenga i Sombhalo zangaphandle. Le divayisi olunembile elawulwa kude, okuyinto ixhunywe qapha kanye antenna;

- ubheke sezingcweti abazokwazi ukuhlanganisa circuit Sombhalo e qapha.
