Indlela yokukhetha nendlela yokuxhuma intambo yokubona yomsindo ku-TV

Intambo yokubona yomsindo uma ixhunywe ku-TV – yiziphi izinzuzo, ukuthi isebenza kanjani, indlela yokukhetha ikhebula lomsindo we-acoustic.

Ukuze usebenze ngobuchwepheshe besimanje, kuba kudingekile ukuqinisekisa ukudluliswa kwenani elikhulu lolwazi ngesivinini esikhulu. Ezimweni eziningi, izintambo zensimbi nezintambo zazisetshenziselwa le njongo. Ezimweni eziningi, babhekana nalo msebenzi, kodwa ngokuhamba kwesikhathi, amakhono abo ngezinye izikhathi angashoda. Le nkinga ibangelwa ukuthi ukudluliswa kwezimpawu zikagesi kunezici ezibalulekile ngezinye izikhathi ezivimbela imingcele yokusebenza edingekayo ukuthi ingafinyelelwa:

1. Lapho imvamisa esetshenzisiwe iphakeme, ukubola kuzokwenzeka ngokushesha.
2. Lapho udlulisela amasignali, amandla asakazwa endaweni ezungezile. Amandla ayanda ngokukhula kwemvamisa.
3. Ukudlula kwamandla ashintshayo kwakha insimu kazibuthe ephazamisa izintambo eziseduze.

Ngakho, lapho udlulisela ulwazi ngesivinini esikhulu phezu kwezintambo zensimbi, kunezici ezivimbela ukwanda okwengeziwe kokusebenza kahle. Ukusetshenziswa kwezintambo ze-fiber optic kuzovumela ukudluliswa kwedatha kwezinye izimiso ezibonakalayo. Umsebenzi wabo umi kanje. Ikhebula liyinqwaba yemicu, ngayinye equkethe ingxenye emaphakathi esobala kanye nomgodla. Lokhu kokugcina akugcini nje ukuvikela imicu ekulimazeni komshini, kodwa futhi kunezakhiwo ezikhanyayo. Ukudluliswa kokukhanya ngefayibha yentambo yokubona:
Umthwali wesignali uyinsimbi yokukhanya, okuthi, ngenkathi idlula ku-fiber, ibonakala ngokuphindaphindiwe ezindongeni zayo, ngaphandle kokulahlekelwa amandla ayo. I-diameter encane izenza ziguquguquke, zivumela ukuthi zihanjiswe noma yikuphi lapho kudingeka khona. Ulwazi lubhalwe ngekhodi ngokumodela ukugeleza kokukhanya ngelaser. Uma ifika lapho iya khona, ukukhishwa kwemfihlo kwenziwa kusetshenziswa isithwebuli sezithombe. Ngakho-ke, amazinga okudlulisa ulwazi afika kuma-terabits amaningana ngomzuzwana angafinyelelwa. Nokho, lesi sivinini esiphezulu singafinyelelwa kuphela ngekhwalithi ephezulu kakhulu ye-fiber optical. Ukusetshenziswa kwayo kunikeza izinzuzo ezilandelayo:

1. Isivinini esiphezulu kanye nenani elibalulekile ledatha edlulisiwe.
2. Izinga eliphezulu lokuvikela ekuphazamisekeni kwangaphandle.
3. I-cross-section encane, evumela ikhebuli ukuthi ihanjiswe noma yikuphi lapho idingeka khona.
4. Abukho ubungozi bokuwohloka obuhambisana nokuba khona kwamandla kagesi aphezulu.
5. Ayikho indlela yokukopisha idatha ngokucashile endleleni yesignali ngaphandle kokulimaza i-fiber.

Kodwa-ke, ngesikhathi sokusebenza kwezintambo zomsindo wedijithali, kuzodingeka ubhekane nalezi zinkinga ezilandelayo:

1. Lapho ubeka, akunakwenzeka ukwenza ukugoba okubukhali. Lokhu kungase konakalise ikhebuli.
2. Ukuze ufunde futhi ubhale ulwazi ngekhebula lomsindo obonakalayo, okokusebenza okukhethekile kuyadingeka.
3. Akunakwenzeka ukuxhuma izintambo usebenzisa ukusonta. Ukufeza lo mgomo, iziphetho kufanele zithengiswe ndawonye.

Ukusetshenziswa kwe-fiber optical ekudluliseni amasignali acoustic kuqinisekisa ukukhiqizwa kwekhwalithi ephezulu. Le ndlela ibhekwa njengekhwalithi ephezulu kakhulu yokudlulisa umsindo we-analog. Izixhumi ezibonakalayo zokudlulisa umsindo ku-TV:
Uma uthumela isignali yomsindo, ukucubungula kwenzeka ngezigaba ezimbalwa:

1. Ukuguqulwa kokuqala kusuka kugesi kuya ku-optical.
2. Ukudluliselwa ngentambo ye-fiber optic.
3. Ukwamukela isignali.
4. Iguqulwa isuke ku-optical iye kwifomu kagesi, bese kudlalwa futhi.

Nakuba kukholelwa ukuthi akunakwenzeka ukusika nokuxhuma izintambo ze-optical, kwezinye izimo lokhu kungenziwa ngesandla, kodwa ngephutha elincane, ikhwalithi yokudlulisela izokwehla kakhulu. Ngakho-ke, kungcono ukusebenzisa lezo zintambo ezikhiqizwa futhi ezilungiselelwe ngendlela yezimboni.

Manje ama-TV ukuze axhumeke asebenzisa isixhumi se-HDMI, esihlinzeka ngesithombe sekhwalithi ephezulu nokudluliswa komsindo. [i-id yamagama-ncazo = “okunamathiselwe_8092″ align=”aligncenter” width=”1080″]

Yiziphi izinhlobo ze-Digital Audio Out Optical ezikhona

Izinga le-S/PDIF lisetshenziselwa ukudlulisa umsindo. Imele “Ifomethi ye-Sony/Philips Digital Interface”. Ukuze uyisebenzise, ​​ungasebenzisa izinhlobo ezimbili zamakhebuli:

1. I- Coaxial isebenzisa izixhumi ze-RCA. Lolu khetho luba yinto yesikhathi esidlule kancane kancane, lunikeza indlela yentambo ye-fiber optic. Nokho, amadivaysi amaningi alalelwayo anezixhumi ezinjalo zokuxhuma. Ingasetshenziswa, kodwa lobu buchwepheshe ngeke bukusize uthole umsindo ophelele. [i-id yamagama-ncazo = “okunamathiselwe_3206″ align=”aligncenter” wide=”488″] Isebenza kanjani intambo ye-coaxial[/caption]
2. I-Fiber optic ibizwa nge-TOSLINK . Ikuvumela ukuthi uthole umsindo omkhulu, kodwa ngesikhathi esifanayo ubuchwepheshe bokuxhuma buhlala bulula. Ukusetshenziswa kwayo kuya ngokuya kuvame.

I-TOSLINK manje isisetshenziswa kakhulu ngaleli zinga, ngakho igama layo kanye ne-S/PDIF kuvame ukusetshenziswa ngokushintshana.
Ukuxhumana okubonakalayo kungaba yi-monomode noma i-multimode. Esimweni sokuqala, ikhwalithi yokudlulisa isignali izoba phezulu, ngoba kumodi ye-multimode, imisebe ibonakala ngama-engeli ahlukene, futhi emabangeni amakhulu lokhu kungaholela ekunciphiseni kwekhwalithi yokudlulisa idatha. Ngesikhathi esifanayo, ikhebuli yemodi eyodwa inenani eliphezulu.

Indlela yokukhetha intambo yokubona yokuxhuma i-TV

Lapho ukhetha, udinga ukulwela ukuqinisekisa ukuthi ikhebula linikeza izinga eliphezulu lokudlulisa umsindo. Ngokwenza kanjalo, udinga ukunaka lokhu okulandelayo:
