Kugadzirira Imba Yako Theatre

Kubatanidza Mutambi

Tinogara tichikurudzira kubatanidza mutambi weBlu-ray Disc (BD) zvakananga kuTV, kunyangwe uine AV Receiver inoti inofambirana neHDMI 2.0 neHDR. AV Receivers vane mukurumbira wekushandisa kugadzirisa kuvhidhiyo, iyo inogona kukanganisa mhando uye inowedzera kuomerwa kuronda pasi zvikonzero zvevhidhiyo zvigadzirwa. Kana zvichikwanisika, tsaura imwe yezvipimo zveTV yako kune yako yepamusoro-mhando sosi, yako Blu-ray Disc player, kunyangwe mamwe ako ese evhidhiyo masosi akafambiswa kuburikidza nemugamuchiri wako.

Kana yako BD player iine yechipiri HDMI yakabuda yeaudio, shandisa icho chinobuda kubatanidza mutambi kuAV Receiver kana audio processor, uye yekutanga HDMI inobuda kuti ubatanidze kuTV.

Kana mutambi achingoburitsa kamwe chete, ona kana TV iine Audio Return Channel (ARC) kana Enhanced Audio Return Channel (eARC) HDMI yekupinda uye AV Receiver yako ine ARC kana eARC HDMI inobuda. Kana zvirizvo, unogona kubatidza ARC kana eARC pamidziyo miviri, woita kuti TV ibvise odhiyo kunze kweiyo HDMI siginecha yakasanganiswa uye woidzosera kune inogamuchira. Chaizvoizvo, eARC inopa kugona kwekutumira odhiyo yeTV "kumashure" paHDMI tambo yakabatana neAV Receiver. Ipapo iwe unokwanisa kubatanidza Blu-ray Disc player kana bhokisi rekushambadzira kune imwe inopinza paTV, uye TV inotumira odhiyo kuburikidza neEARC, kudzokera kune inogamuchira. Vhidhiyo yakasanganiswa + odhiyo inoenda kubva kumutambi kuenda kuTV pane imwe yeTV yekupinza chiteshi, uye ipapo odhiyo inodzokera kuAV Receiver pane imwe nzira yekupinza yeTV (iyo mune iyi kesi inova yekubuda kweaudio - kuvhiringa zvishoma!)

Semuenzaniso, ngatiti mugamuchiri ane eARC pane yayo HDMI 1 kubuda, uye TV ine eARC pane yayo HDMI 2 yekupinda. Iwe waizobatanidza iyo AV Receiver's HDMI 1 inobuda kuTV's HDMI 2 yekupinda, uye shandisa menyu pamidziyo miviri kugonesa eARC. Iwe waizoseta inogamuchira kune eARC yekuisa (dzimwe nguva yakanyorwa kuti "TV"). Ipapo waizobatanidza yako Blu-ray Disc player inobuda kune imwe inopinza paTV, semuenzaniso TV yeHDMI 1 yekupinda. Kana uine mimwe midziyo yakabatana neAV Receiver pane zvimwe zvinogamuchira zvinogamuchira, haungashandise eARC pamidziyo iyoyo - unochinja chibatiso kuenda kuchiteshi cheHDMI icho midziyo iyoyo yakabairwa, wobva waisa TV kuHDMI 2. iyo nyaya, eARC haishande uye chiratidzo chetani chakatwasuka: Playback Chishandiso -> Receiver -> TV.

Kana imwe yeidzi sarudzo ichishanda neimba yako yemitambo, ungangoda kufambisa kuburitswa kwemutambi wako kuburikidza neAV Receiver yako kuti utore odhiyo yekutamba. Kana ukawana zvigadzirwa zvevhidhiyo panguva yekuyedzwa kwako nekugadzirisa, funga kwechinguva kubatanidza mutambi zvakananga kuTV kuti uone kana zvigadzirwa zviri kukonzerwa neAV Receiver. Kana vari, zvirinani iwe unozoziva uye unogona kuisa izvo mune yako ramangwana imba theatre yekuvandudza zvirongwa.

Ita shuwa kuti uri kushandisa HDMI tambo dzakayerwa 18Gb/s kana zvirinani, uye/kana HDMI 2.0 kana zvirinani. Unongoda tambo dzeHDMI dzegiredhi iri rekubatanidza kubva kumutambi kuenda kuTV kana vhidhiyo iri kusvetuka mugamuchiri uye yakananga kuTV. Kana vhidhiyo ichifambiswa kuburikidza neanogamuchira kana yechipiri switchbox, tambo dzinobva kumutambi kuenda kune inogamuchira kana switchbox uye tambo dzinobva kune inogashira kana switchbox kuenda kuTV dzinoda kuverengerwa 18Gb/s.

Mashoko Okuwedzera: Technical Notes Mamwe manotsi pamusoro pekurongeka uye mazinga:

Mazhinji emhando yepamusoro anoshandiswa mukati meindastiri anogadzirwa aine 8 mabhiti echokwadi, kunyangwe nhasi kana 10-bit vhidhiyo inoshandiswa zvakanyanya kune HDR pane ese madhisiki uye kutepfenyura. Izvi zvinogona kunge zvisingaite sedambudziko rakawanda, asi zvinounza zvikanganiso, zvimwe zvacho zvinogona kuoneka, uye zvese zvinokanganisa michina yekuyeresa. Takatoona madhisiki emazuva ano ebvunzo anoshandisa 8-bit master mifananidzo yakashandurwa kuita gumi-bit nekuwanza ese mapixel values.

Zvaisazoita senge 2 mamwe mabheti echokwadi angave akakosha kudaro, asi iwo maviri ekuwedzera mabheti anopeta nhamba yemazinga akapatsanurwa anogona kuratidzwa mune yega yega tsvuku, girinhi uye yebhuruu chiteshi, uye izvi zvinogona chaizvo kuderedza zvikanganiso. .

Semuenzaniso, ngatiti isu tinoda kugadzira 50% grey hwindo (iyi 50% kukurudzira, iyo yakasiyana ne50% mutsara - zvimwe pane izvo gare gare). Nhamba yekodhi ye0% mu8-bit ndeye 16, uye kukosha kwekodhi ye100% i235, saka 50% inenge iri (16 + 235) / 2, iyo 125.5. Kazhinji izvi zvinotenderedzwa kusvika 126, asi zviri pachena kuti zvakanyanyisa kukwirira. 125 ingave yakaderera zvishoma. 126 inobuda kusvika pa50.23%, iri mhosho huru kana uri kuyedza kuwana zviyero zvakaringana zvemhando yepamusoro yekuenzanisa. Kusiyana neizvi, uchishandisa 10-bit kodhi kodhi, unogona kunyatsomiririra 50% sekodhi kukosha, sezvo mu10-bit huwandu huri 64 940, uye (64 + 940) / 2 = 502.

Nepo 50% ichiitika kuti ibude zvakakwana mumabhiti gumi, 10% haabudi, uye hapanawo 51% kana 52% kana chero imwe nhamba yakazara kunze kwe53% ne0%. Kushandisa iyo yakazara gumi mabhiti kunoderedza kukanganisa zvakanyanya, asi kana chinangwa chako chiri chekusvika padyo nekukwana sezvinobvira, iwe unoda chaizvo kusundira kukanganisa kwakadzika sezvinobvira, uye ndipo panopinda dither.

Kana mita yakareruka kana colorimeter ikayera hwindo kana chigamba pachiratidziri, haisi kuyera kukosha kwepikisi imwe chete, iri kunyatso kuyera avhareji yemazana emapikisi ayo ese anowira mukati meyero denderedzwa. Nekusiyanisa chiyero chepixels mudenderedzwa rechiyero, tinogona kugadzira chaiwo makosi nezvikanganiso zvisina basa. Semuenzaniso, kana tichida nhanho inowira pakati pepakati pakati pekodhi kukosha 10 uye kodhi kukosha 11, isu tinogona kuita hwindo redu kupararira kwehafu-random uko hafu yemapikisi ari pakodhi 10 nehafu pakodhi 11, iyo inoyera sezvakangoita. hafu pakati pekupenya kunotarisirwa kodhi 10 uye kodeti 11. Izvo zvinoshandawo kune kurongeka kwemavara; nekudzika pakati pemavara akasiyana ari pedyo isu tinogona kurova padhuze nepazvinogoneka nemuviri kune chaiyo match yeruvara rwatinoda kuratidza.

Linear vs. Stimulus (% code value) Levels
Iyi inguva yakanaka seyese yekusiyanisa pakati pemhando dzakasiyana dzemazinga. Iwe unogona kunge wakaona mune yedu mapatani kana kubatsira mameseji kuti patani iri pa "50% kodhi kukosha" kana "50% mutsara" uye kunze kwekunge uine kumashure muvhidhiyo kana dzidziso yeruvara zvingave zvakaoma kunzwisisa mutsauko. Heino (yakanyanya) gidhi yekukurumidza:

Mukunaka kwese mafomu edhijitari ekuratidzira uye kufungidzira anoshandiswa nhasi, pane chimwe chinhu chinodaidzwa kuti "transfer function" iyo inomepu kukosha kwekuisa kunotumirwa muchiratidziro ("code word" values) kune chaiwo mwenje mazinga anogadzirwa nemuviri nechiratidziro. "mutsara" tsika). MuVhidhiyo yeStandard Dynamic Range (SDR), basa rekufambisa rinenge riri nyore curve yemagetsi, apo L = SG, apo L iri mutsara Luminance, S ndiyo isiri-mutsara yekukurudzira kukosha, uye G i gamma. Muvhidhiyo yeHDR, basa rekutamisa rakanyanya kuomarara, asi richiri rakaita senge rakareruka simba curve.

Basa rekuchinjisa rinoshandiswa mukufungidzira nekuti rinoratidzira kumaonero emunhu ekuchinja kwechiyero chechiedza. Meso ako anonyanya kutarisisa kune shanduko muyero yechiedza pamucheto wezasi wechiyero chekupenya pane kumagumo. Saka nekushandisa iyi curve kumiririra mwenje mazinga, iyo encoded mifananidzo kana vhidhiyo inogona kuisa akawanda macode values ​​pedyo nedema, painodiwa, uye mashoma pedyo nechena, paasingade zvakanyanya. Kuti ndikupe imwe pfungwa yekuti zvinoshanda sei mukuita, mu10-bit HDR encoding, ichibva pacode value 64 kusvika 65 inomiririra shanduko yelinear light level ye0.00000053%, ukuwo kubva pacode value 939 kusvika 940 inomiririra shanduko ye1.085 %.

Kana izvozvo zvichiita kuti musoro wako urwadze, usazvidya mwoyo, zvishoma zvakaoma kuputira musoro wako. Mhedzisiro ndeyekuti, toti, 25% kukurudzira haisi hafu inopenya se50% kukurudzira, zvirinani kwete muzvikamu zvemuviri zvakayerwa nemamita mwenje. Iwe unogona kuwana, zvichienderana nebasa chairo rekutamisa riri kushandiswa, kuti 25% yekukurudzira inotarisa hafu inopenya se50% kukurudzira, nekuda kwekusiyana kwakambotaurwa mukuona muhurongwa hwekuona kwevanhu, asi ziso remunhu hariyere chiedza. semita yechiedza.

Chimwe chinhu chakakosha kuziva ndechekuti neHDR yemazuva ano, zvakajairika kupa mutsara mitsara mune asolute luminance units, yakapihwa se "makenduru pamamita akaenzana" kana "cd/m2". (Zita remadunhurirwa rechikamu ichi nderekuti “nits,” saka kana ukaona “1000 nits” iri shorthand rekuti “1000 cd/ m2”.)

Kana uchiona nhamba dzenhamba mumapateni edu, kana ukaona izwi rekuti “mutsara” kana kuona kuti mayunitsi acho ari cd/m2, unogona kuva nechivimbo chekuti nhamba dzacho dzine mutsara uye dzinomiririra huwandu hwemuviri hwaunogona kuyera.

Kana ukaona macode values, kana kuona mavara akaita se“% code value” kana “% stimulus” kana even percent value isina qualifier, idzo dzinenge dzagara dziri manhamba ekusimudzira, ayo asingaratidzi mutsara kune chaiwo akayerwa kupenya mwero.

Musiyano wakakosha pakati peizvi ndewekuti kana iwe ukapeta kaviri kana nehafu yakapihwa yekukurudzira muzana kana kukosha kwekodhi, kupenya kwakayerwa hakupete kana hafu, asi kunoshanduka zvichienderana nebasa rekufambisa razvino. Uye neazvino HDR ekufambisa mabasa, kupetwa kaviri kwekukurudzira kunogona kumiririra zvakapetwa kaviri kwekupenya kwemutsara, saka manzwisisiro ako ekuti kupenya kunofanirwa kuita chimwe chinhu kunoenderana sei kune chimwe kungave kwakashata. Usanetseke; ndizvo zvakajairika kunyangwe kune vanhu vanoshanda nevhidhiyo nguva dzese.

Pazasi pane tafura inoratidza hukama pakati peiyo linear light values ​​(mu cd/m2), normalized linear percentage, stimulus percentage, and the nearest code value in 10-bit limited-range encoding. Zvese izvi zvinotora ST 2084 yekufambisa basa, iro basa rinoshandiswa neazvino HDR encoding.
