Funda i-Ins ne-Outs ye-HD Entertainment ku-Ikhompyutha Yakho Yesikrini
Okwamanje, wonke umuntu wezwa nge-high-definition ithelevishini (i-HDTV). Iphoyinti lokuthengisa le-flat-panel panel ye-plasma ne-LCD esizibonise ngokuzumayo emakamelo okuphila abantu, futhi yenza imidlalo, amabhayisikobho ngisho neThe Weather Channel ibheke ngendlela emangalisayo. Abantu abaningi banombono ongacacile wokuthi iyiphi incazelo ephakeme , noma "i-HD," ehlinzeka ngethelevishini: isithombe esihle, esicacile-ecacile nemibala enamandla. Kodwa kusho ukuthini ukuba nesilondolozi se-HD esifakwe kwikhompyutha yakho? Ingabe ikhona iphuzu? Ingabe yenza i-computing kangcono kakhulu?
Ngamafuphi, kuxhomeke kulokho okwenzayo ngekhompyutha yakho. Ukuze ube yi-briefer, yebo, kungcono.
Incazelo yeNcazelo Ephezulu
"Incazelo ephezulu" yikhizi eliyinkinga, ethatha isimo sezinto eziningi ezihlukahlukene. Okuwukuphela kwencazelo evunyelwe ngokuvamile ukuthi kukhona into enhle kakhulu yesithombe kanye nokucaca.
Ngokomqapha we-PC, incazelo ephakeme iyinkulumo efana nesinqumo esiphezulu. Isinqumo esiphezulu, sisho amaphikseli amaningi nge-intshi kwesikrini sakho - futhi amaphikseli amaningi nge-inch, ngcono ukubonisa. I-PC ephezulu yokucacisa i-PC, ke, ihambisa isithombe esicacile ngokucacile kunokuba kunokwenzeka nge-definition ephansi, izikrini ezisezingeni eliphansi.
Amazinga Wevidiyo Ahlala Akhona
Njengabaqaphi be-PC ephezulu-ncazelo baye baqhubekela phambili emakethe, izindinganiso ziye zashintsha ukuvumela incazelo engaphezulu yokukhonkolo ye-HD kunakudala.
Lokhu okulandelayo yizincazelo ezijwayelekile zevidiyo ye-HD, engaboniswa kubaqapheli bezinqumo ezihlukahlukene zendabuko - okunye okulinganiselwe izikrini zekhompyutha, enye yezikrini ze-TV - kodwa, ngokukhululeka, ziyashintsha ngoba bonke bayasebenza ukubonisa lezi zinqumo zevidiyo:
- 1280x720 (aka, 720p)
- 1920x1080 (aka, 1080i)
- 1920x1080 okuqhubekayo (aka, 1080p)
Ukuqhubekela phambili ngokumelene ne-Interlaced Scanning
I "i" ne "p" ichaza ukuskena okuqhubekayo nokuqhubekayo, ngokulandelana. Ukuskena kwe-interlaced ubuchwepheshe obudala bobabili. Umqapha we-PC osebenzisa ukuskena okuhamba phambili kuvuselela uhhafu wemigqa yephikseli enezingqimba emjikelezweni owodwa futhi uthatha omunye umjikelezo ukuze uvuselele enye ingxenye, ngenkathi ukhetha imigqa. I-upshot yukuthi ama-scans amabili ayadingeka ukuze abonise umugqa ngamunye, okuholela ekuboniseni okuhamba kancane, okubonakalayo nge-blurrier nge-flickering. Ukuskena okuqhubekayo , ngakolunye uhlangothi, kuhlola umugqa owodwa ophelele ngesikhathi, ngokulandelana kusuka phezulu kuya phansi. Ukuboniswa okwenziwe kubushelelezi futhi kuningiliziwe - ikakhulukazi umbhalo, isici esivamile ezikrini ezisetshenziselwa ama-PC.
I-HD: Izinga Elilandelayo Emakhokheni we-PC
I-PC yakho, incazelo ephezulu yenza umehluko omkhulu uma kuziwa ukudlala imidlalo yevidiyo, ukubukela ama-movie nokubukela i-HD yevidiyo e-inthanethi, futhi. I-HD kusho ukuthi uzobukela "kusikrini esikhulu" - njengoba ekuqaleni kwakuhloswe ukuba kubonwe, kungabanjwanga, kumidlalo yaseshashalazini. Njengoba i-HDTV ibanjwe, ama-studios wegeyimu yevidiyo kanye nezinkampani zokuzijabulisa ezise-intanethi ziye zagxila kakhulu kuhlelo lwe-HD yeskrini esiphezulu.
Iphuzu eliyinhloko: Uma ungenayo i-PC ye-high definition definition, awukho engxenyeni enkulu yesithombe.
