DVD

DVD yakhala yopambana kwambiri, ndipo ndithudi idzakhala pafupi kwa nthawi ndithu. Ngakhale kuti zakhazikitsidwa, DVD sizitanthauzira kwambiri. Ma DVD amawulutsa mavidiyo pa NTSC 480i (720x480 pixel) pamakina osakanikirana, ndi kujambula ma DVD omwe angathe kupanga DVD mavidiyo mu 480p (720x480 pixels omwe amawonetsedwa pang'onopang'ono). Ngakhale DVD ili ndi kuthetsa kwakukulu komanso khalidwe lachifaniziro, poyerekeza ndi VHS ndi televizioni yamakono, imangotsala pang'ono kuthetsa HDTV.

Kuwongolera - Kupeza Zambiri Zambiri pa DVD

Poyesera kuti mulingo wa DVD ukhale wotchuka pa ma HDTV a lero, opanga ambiri amapanga mphamvu zowonjezera kudzera mu DVI ndi / kapena HDMI okhudzana ndi ma DVD pa atsopano a DVD.

Kuwongolera ndi njira yomwe masamu amawerengetsera kuwerengera kwa pixel ya zotsatira za ma DVD pa chiwerengero cha pixel chakuthupi pa HDTV kapena Ultra HD TV, yomwe ingakhale 1280x720 (720p), 1920x1080 (1080i) , 1920x1080p (1080p) , kapena 3840x2160 (4K) .

Kukonzekera kumaphatikizapo ntchito yabwino yofananitsa ndi pulogalamu ya DVD yomwe imachokera ku DVD yomwe imapanga mafilimu a HDTV. Komabe, upscaling silingathe kusintha zithunzi za DVD zomwe zimakhala zenizeni.

Mawonekedwe a Blu-ray ndi Mafilimu Osewera

Kuwonjezera pa Mafomu a Blu-ray Disc ndi Zomwe amavomerezera. Pali atatu "Mbiri" zomwe ogula amafunika kuzidziwa. Mauthenga awa amaphatikizapo mphamvu za ochita Blu-ray Disc, ndipo agwiritsidwa ntchito ndi Blu-ray Disc Association motere:

• Mbiri 1.0 - Mbiriyi imapanga osewera Blu-ray omwe anapangidwa pamaso pa November 2007. Osewera m'gulu ili ali ndi chiwonetsero chimodzi cha kanema ndi intaneti. Izi zikutanthawuza kuti osewerawa sangathe kupeza PIP (Chithunzi-mu-Chithunzi) chokhala ndi ma CD Blus ray, komanso sangathe kulumikiza zomwe zili pa webusaiti zomwe zimaphatikizidwa pa ma DVD Blus ray. Monga gawo la mbali, onse osewera HD-DVD amafunika kukhala ndi maluso awa omwe amamangidwa kuchokera tsiku limodzi.
• Mbiri 1.1 - Pulojekitiyi imapanga makina opanga mafilimu / mavidiyo ndi 256 MB yosungirako zojambula ku mafilimu onse a Blu-ray omwe adatulutsidwa pambuyo pa November 1st, 2007. Izi zimathandiza kuti pakhale ndemanga zowonongeka za PIP ndi zina zomwe zikuphatikizidwa kuphatikizapo Blu- Malonda a ray (omwe amatchedwanso "Bonus View"). Zolemba zina 1.1 osewera amavomerezanso kulumikiza mwachindunji ku zowonjezeredwa za firmware. Komabe, sikofunikira kuti sewero la Blu-ray likhale ndi intaneti kuti likhale lovomerezeka ngati Profile 1.1.
• Mbiri 2.0 - Mbiriyi imatchedwa "BD-Live". Zili ngati Profile 1.1, koma imapanga mphamvu yosungiramo zosamalidwa za 1GB ndipo imaphatikizapo kuphatikizidwa kwa mgwirizano wa Ethernet, womwe umathandiza kusintha zambiri pakupeza zina zowonjezera zomwe zingaphatikizidwe pa Blu-ray Discs ndi njira yowonjezera yopezeka kudzera pa intaneti kudzera malo otsegula kwambiri pa intaneti. Izi zimabweretsa mafilimu a Blu-ray ku malo omwewo monga osewera HD-DVD kuyambira pakuyambitsidwa koyambirira kwa mawonekedwe osayenera.

Cholinga chake n'chakuti ma CD Blu-ray onse, mosasamala kanthu za mbiri yawo, adzakhala osewera pa osewera a Blu-ray Disc.

Kwa Blu-ray, malo atsopano amafunika kupanga mafoni ndi osewera komanso kubwereza mafilimu. Komabe, chifukwa chakuti zida za HD-DVD zimakhala zofanana kwambiri ndi DVD yapamwamba, zomera zambiri zomwe zimapanga kupanga DVD, ma disks, ndi mafilimu omwe angagwiritsidwe ntchito akhoza kugwiritsa ntchito HD-DVD.

Ngakhale HD-DVD ili ndi ubwino wokhala ndi zosavuta kupanga, zomwe zingapangitse kuti ndalama zowonongeka zitheke, ubwino waukulu wa Blu-ray pa HD-DVD ndi mphamvu yosungirako. Chifukwa cha mphamvu zazikulu za disk, Blu-ray disc imatha kukhala ndi mafilimu omwe amatha nthawi zonse komanso zinthu zina.

Pofuna kuthana ndi izi, HD-DVD inagwiritsira ntchito zipangizo zamakono, komanso kugwiritsa ntchito zipangizo zamakono zowononga VC1, zomwe zimapangitsa kuti zinthu zitheke, popanda kutaya khalidwe, pa diski yaing'ono yosungirako mphamvu. Izi zinathandiza kuti HD-DVD ikhale ndi maonekedwe ena komanso mafilimu ambiri pa diski imodzi.

Blu-ray Ndipo HD-DVD Kupezeka

Osewera Blu-ray akupezeka padziko lonse lapansi, pamene ma DVD atsopano a DVD sapezeka, magulu ogwiritsira ntchito kapena ma DVD omwe sagwiritsidwe ntchito angakhalepo kudzera m'mapwando awo (monga eBay).

DVD tsopano ndiyo mtundu wopanga zosangalatsa kwambiri m'mbiri, ndipo osewera Blu-ray onse (ndi magulu onse a HD-DVD omwe akugwiritsabe ntchito) akhoza kusewera ma DVD . Izi sizinali choncho ndi VHS mpaka DVD, monga DVD / VHS osewera combo osewera sanabwere msika mpaka zaka zingapo pambuyo pa DVD.

Ngakhale Blu-ray ndi HD-DVD osewera akubwerera motsatira DVD yachizolowezi, iwo sakugwirizana. Zolemba ndi mafilimu mwawonekedwe imodzi sizidzasewera m'zigawo zina. Mwa kuyankhula kwina, simungathe kusewera filimu ya Blu-ray pa sewero la HD-DVD, kapena mosiyana.

Zothetsera Zotheka Zomwe Zingathetse Mavuto a Blu-ray ndi HD-DVD

Njira imodzi yomwe ingathetsere kusagwirizana kwa Blu-ray Disc ndi HD-DVD yomwe yatulutsidwa ndi LG, inayambitsa sewero la Blu-ray Disc / HD-DVD.
