Npaj Koj Tsev Ua Yeeb Yam

Txuas lub Player

Peb ib txwm pom zoo kom txuas Blu-duab tshav Disc (BD) player ncaj qha mus rau TV, txawm tias koj muaj AV Receiver uas hais tias nws sib xws nrog HDMI 2.0 thiab HDR. AV Receivers tsis muaj npe nrov rau kev ua ntawv thov rau kev yees duab, uas tuaj yeem cuam tshuam qhov zoo thiab ntxiv qhov nyuaj rau kev taug qab cov hauv paus ua rau cov duab kos duab. Yog tias ua tau, muab ib qho ntawm koj lub TV tso rau hauv koj qhov chaw zoo tshaj plaws, koj lub Blu-duab tshav Disc player, txawm tias tag nrho koj lwm qhov video tau dhau los ntawm koj lub receiver.

Yog tias koj tus BD player muaj qhov thib ob HDMI tso zis rau lub suab, siv cov zis tawm los txuas tus neeg uas ua ntawv mus rau AV Receiver lossis audio processor, thiab thawj HDMI tso zis los txuas rau TV.

Yog tias tus neeg uas ua ntawv tsuas muaj ib qho tso zis xwb, saib seb lub TV puas muaj Audio Return Channel (ARC) lossis Enhanced Audio Return Channel (eARC) HDMI input thiab koj AV Receiver muaj ARC lossis eARC HDMI tso zis. Yog tias muaj, koj tuaj yeem qhib ARC lossis eARC ntawm ob qho khoom siv, thiab kom lub TV strip lub suab tawm ntawm HDMI teeb liab ua ke thiab xa rov qab mus rau lub receiver. Yeej, eARC muab lub peev xwm xa TV lub suab "rov qab" ntawm HDMI cable txuas nrog AV Receiver. Tom qab ntawd koj tuaj yeem txuas Blu-duab tshav Disc player lossis streaming lub thawv rau lwm lub tswv yim ntawm TV, thiab TV yuav xa lub suab ntawm eARC, rov qab mus rau lub receiver. Cov yees duab ua ke + suab mus los ntawm tus neeg uas ua ntawv mus rau TV ntawm ib qho ntawm TV cov kev tawm tswv yim, thiab tom qab ntawd lub suab rov qab mus rau AV Receiver ntawm lwm lub TV input channel (uas qhov no dhau los ua suab tso tawm - me ntsis ruam!)

Piv txwv li, piv txwv li tus receiver muaj eARC ntawm nws HDMI 1 tso zis, thiab lub TV muaj eARC ntawm nws HDMI 2 input. Koj yuav txuas lub AV Receiver's HDMI 1 tso zis rau TV's HDMI 2 input, thiab siv cov ntawv qhia zaub mov ntawm ob qho khoom siv los pab eARC. Koj yuav teeb lub receiver rau eARC cov tswv yim (qee zaum sau tias "TV"). Tom qab ntawd koj yuav txuas koj lub Blu-duab tshav Disc neeg uas ua ntawv tso zis rau lwm lub tswv yim ntawm lub TV, piv txwv li TV's HDMI 1 input. Yog tias koj muaj lwm yam khoom siv txuas nrog AV Receiver ntawm lwm lub receiver inputs, koj yuav tsis siv eARC rau cov khoom siv ntawd - koj yuav hloov lub receiver mus rau HDMI channel uas cov khoom siv tau ntsaws rau hauv, thiab teeb lub TV rau HDMI 2. Cov ntaub ntawv ntawd, eARC tsis siv thiab cov hlua teeb liab ncaj qha: Playback Device -> Txais -> TV.

Yog tias ob qho ntawm cov kev xaiv no tsis tuaj yeem ua haujlwm nrog koj lub tsev ua yeeb yam, tej zaum koj yuav xav tau kev tso tawm ntawm koj cov neeg ua si los ntawm koj tus AV Receiver thiaj li yuav tau txais lub suab ua si. Yog tias koj pom cov duab kos duab thaum koj sim thiab hloov kho, xav txog kev txuas tus neeg uas ua ntawv ncaj qha mus rau TV ib ntus kom pom tias cov khoom cuav yog tshwm sim los ntawm AV Receiver. Yog tias lawv yog, tsawg kawg koj yuav paub thiab tuaj yeem ua qhov ntawd rau hauv koj lub tsev ua yeeb yam hauv tsev yav tom ntej.

Nco ntsoov tias koj siv HDMI cables ntsuas rau 18Gb / s lossis zoo dua, thiab / lossis HDMI 2.0 lossis zoo dua. Koj tsuas yog xav tau HDMI cables ntawm qib no rau kev sib txuas ntawm cov neeg uas ua ntawv mus rau TV yog tias cov vis dis aus hla lub receiver thiab mus ncaj qha rau TV. Yog hais tias cov vis dis aus raug xa mus los ntawm lub receiver lossis lwm lub switchbox, cov cables los ntawm cov neeg uas ua ntawv mus rau lub receiver los yog switchbox thiab cov cables los ntawm lub receiver los yog switchbox rau lub TV yuav tsum yog 18Gb / s rated.

Enabling Advanced Video Nta ntawm TV

Ntau lub TVs tuaj txog nrog ntau yam kev ua haujlwm tsis zoo uas koj tuaj yeem xav qhib, xws li bitrates siab dua, txuas xim gamut lossis Dolby Vision. Qee tus ntawm lawv yuav cia li qhib cov yam ntxwv no yog tias lawv pom lub cuab yeej siv tau txuas nrog, lwm tus yuav qhia rau koj tias koj yuav tsum ua kom cov yam ntxwv no, thiab qee tus tsuas yog tsis kam tso cai sib txuas nrog cov yam ntxwv no kom txog thaum koj qhib lawv tus kheej.

Hauv qab no yog cov lus qhia rau kev ua kom cov yam ntxwv no ntawm ntau lub TV sib cuam tshuam. TV interfaces tuaj yeem hloov pauv xyoo mus rau xyoo, yog li nrhiav cov chaw no yuav cuam tshuam me ntsis ntawm poking nyob rau hauv cov ntawv qhia zaub mov lossis nyeem cov ntu cuam tshuam ntawm koj lub TV cov lus qhia siv:

Ua ntej, xaiv cov zaub Cinema, Movie lossis Filmmaker duab hom, uas feem ntau yog hom tawm ntawm lub thawv. Daim duab-hom teeb no feem ntau pom nyob rau hauv cov zaub cov duab zaub mov.

Qee lub TV muaj ntau dua ib hom xinesmas; Piv txwv li, qee lub LG TVs default rau Cinema Tsev, tab sis hom ntawv sau npe Cinema yog qhov zoo tshaj plaws. Koj tuaj yeem txheeb xyuas qhov no los ntawm kev tso saib HDR Xim Qhov Kev Ntsuas Tus Qauv thiab saib ntawm ST2084 Txoj Kev Taug Kev (saib daim duab 4). Txhua daim duab plaub hauv ntu ntawd zoo li grey-raws li nws yuav tsum-thaum koj xaiv hom xinesmas hauv 2018 lossis 2019 LG TV. Ib yam li ntawd, hom zoo tshaj plaws hauv Sony TVs hu ua Cinema Pro.

Tom ntej no, xyuas kom meej tias cov xim kub yog teem rau sov, uas yog feem ntau yog qhov tseeb xim-temperature teeb. Cinema daim duab hom ib txwm ua rau qhov chaw no, tab sis nws yog ib lub tswv yim zoo los muab ob npaug rau. Cov xim-kub qhov chaw feem ntau pom tob hauv cov zaub cov duab ntawv qhia zaub mov nyob rau hauv "advanced settings" section.

Ntau Sony thiab Samsung TVs muaj ob qhov chaw sov: Warm1 thiab Warm2. Xaiv Warm2 yog tias nws tsis ua haujlwm lawm. Tsis tas li ntawd, cov tshiab Vizio TVs tsis muaj qhov sov so txhua qhov; Nyob rau hauv tas li ntawd, xaiv Normal.

Lwm qhov chaw tseem ceeb los xyuas yog feem ntau hu ua Daim Duab Loj lossis Aspect Ratio. Cov kev xaiv muaj rau qhov chaw no feem ntau suav nrog 4: 3, 16: 9, ib lossis ntau qhov chaw hu ua Zoom, thiab cia siab tias, ib qho hu ua qee yam xws li Dot-by-Dot, Tsuas Scan, Full Pixel, 1: 1 Pixel Mapping, lossis ib yam dab tsi zoo li ntawd. Qhov teeb tsa nrog lub npe zoo li cov neeg kawg no qhia txhua pixel hauv cov ntsiab lus raws nraim qhov nws yuav tsum nyob ntawm qhov screen, uas yog qhov koj xav tau.

Vim li cas thiaj muaj qhov chaw uas tsis tso tawm txhua pixel hauv cov ntsiab lus raws nraim qhov nws yuav tsum nyob ntawm qhov screen? Ntau qhov chaw cuam tshuam cov duab los sau lub vijtsam, txav pixels nyob ib puag ncig thiab txawm tias tsim cov pixels tshiab los ua li ntawd. Thiab qee qhov chaw ncab cov duab puas tau me ntsis hauv cov txheej txheem hu ua "overscanning," uas tau siv hauv analog TVs los nkaum cov ntaub ntawv ntawm cov npoo ntawm txhua tus ncej uas yuav tsum tsis pom rau cov neeg saib. Qhov no tsis cuam tshuam rau lub hnub nyoog ntawm digital TVs thiab tshaj tawm, tab sis ntau lub tuam txhab tseem ua nws.

Nyob rau hauv txhua rooj plaub no, tus txheej txheem ntawm stretching daim duab - uas yog hu ua "scaling" - softens cov duab, txo cov ntsiab lus koj pom. Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws los ntawm Ultra HD Benchmark, koj yuav tsum xyuas kom meej tias txhua qhov kev ntsuas, suav nrog overscanning, yog neeg xiam. Xaiv Dot-by-Dot, Tsuas Scan, Full Pixel, lossis txawm tias koj lub TV hu 1: 1 pixel daim ntawv qhia.

Hisense TVs muaj cais Daim Duab Loj thiab Overscan tsis. Tig Overscan tawm thiab teeb tsa Daim Duab Loj rau Dot-by-Dot.

Txhawm rau kom paub tseeb tias koj tau ua tsis taus txhua qhov kev ntsuas, tso saib Cov Duab Cropping Pattern, uas pom nyob rau hauv Advanced Video-> Kev Ntsuas cov ntawv qhia. Ib lub checkerboard ib-pixel tshwm nyob rau hauv nruab nrab ntawm tus qauv ntawd. Yog tias scaling / overscanning yog neeg xiam, lub checkerboard zoo nkaus li grey. Txwv tsis pub, lub checkerboard yuav muaj qhov txawv txav hu ua "moiré." Thaum koj xaiv 1: 1 pixel mapping, moiré yuav tsum ploj mus.

OLED TVs feem ntau muaj lub luag haujlwm hu ua "orbit," uas txav tag nrho cov duab nce, nqis, sab xis, thiab sab laug los ntawm ib lub pixel ib zaug kom txo tau cov duab khaws cia lossis "hlawv hauv."

Yog tias qhov tshwj xeeb no tau qhib-uas feem ntau yog los ntawm lub neej ntawd-qhov kawg ntawm ib qho ntawm Cov Duab Cropping tus qauv duab plaub uas sau tias "1" yuav tsis pom. Tua tawm lub orbit muaj nuj nqi los xyuas kom meej tias koj tuaj yeem pom tag nrho plaub lub duab plaub uas sau tias "1."

Tom ntej no, xyuas kom meej tias tag nrho TV lub npe hu ua "txhim kho" cov yam ntxwv yog neeg xiam. Cov no feem ntau suav nrog thav duab interpolation, dub-theem expansion, dynamic contrast, ntug txhim kho, txo suab nrov, thiab lwm yam. Feem ntau ntawm cov "txhim kho" no ua rau cov duab zoo, yog li muab lawv tso rau hauv dav dav.

Rau cov qauv dynamic ntau, cov zaub qhov teeb tsa gamma yuav tsum nyob ze li 2.4 li sai tau. Yog tsis tau txais kev tshaj lij, gamma txiav txim siab seb cov zaub teb li cas rau cov lej sib txawv hauv cov teeb liab video. Cov qauv kev xeem SDR tau paub zoo nrog gamma ntawm 2.4, yog li ntawd yog qhov zaub yuav tsum tau teeb tsa.

Raws li koj tuaj yeem xav tau los ntawm tam sim no, cov tuam txhab sib txawv qhia qhov teeb tsa gamma txawv. Qee qhov qhia txog tus nqi gamma tiag tiag (piv txwv li, 2.0, 2.2, 2.4, thiab lwm yam), thaum lwm tus qhia tus lej tsis txaus ntseeg (xws li 1, 2, 3, thiab lwm yam). Yog tias nws tsis paub meej tias qhov tseeb gamma tus nqi yog los ntawm lub npe hauv cov ntawv qhia zaub mov, qhov zoo tshaj yog cia nws nyob ib leeg.

Basic Player Settings

Ultra HD Blu-duab tshav players muab lawv tus kheej txheej ntawm kev tswj uas koj yuav tsum tau xyuas. Qhib tus neeg ua si cov ntawv qhia zaub mov thiab saib seb nws puas muaj cov duab-kho kev tswj hwm (xws li ci ntsa iab, qhov sib piv, xim, tint, sharpness, txo suab nrov, thiab lwm yam). Yog tias muaj, xyuas kom tseeb tias lawv tau teeb tsa rau 0/Off. Tag nrho cov kev tswj hwm no yuav tsum tau kho hauv TV, tsis yog tus neeg ua si.

Zoo li txhua tus neeg ua si muaj kev tswj hwm qhov kev daws teeb meem, uas rau cov neeg ua si feem ntau yuav tsum tau teeb tsa rau UHD / 4K / 3840x2160.

Cov lus qhia ntxiv: Technical Notes Ib co lus hais txog qhov raug thiab qib:

Cov qauv classic feem ntau siv thoob plaws hauv kev lag luam yog tsim nrog 8 khoom ntawm qhov tseeb, txawm tias niaj hnub no thaum 10-ntsis video siv dav rau HDR ntawm ob qho tib si disc thiab streaming. Qhov no yuav tsis zoo li muaj teeb meem ntau, tab sis nws inevitably qhia txog kev ua yuam kev, qee qhov tuaj yeem pom, thiab txhua yam cuam tshuam rau cov khoom ntsuas. Peb tau pom cov qauv sim niaj hnub no siv 8-ntsis master dluab hloov dua siab tshiab rau 10-ntsis los ntawm kev muab tag nrho cov txiaj ntsig pixel.

Nws yuav tsis zoo li 2 cov khoom ntxiv ntawm qhov tseeb yuav yog qhov tseem ceeb, tab sis ob qho ntxiv ntxiv plaub npaug ntawm cov qib sib cais uas tuaj yeem tshwm sim hauv txhua qhov liab, ntsuab thiab xiav raws, thiab qhov no tuaj yeem txo qhov yuam kev. .

Piv txwv li, piv txwv li peb xav tsim ib lub qhov rais 50% grey (qhov no yog 50% stimulus, uas txawv ntawm 50% linear - ntxiv rau tom qab ntawd). Tus nqi code rau 0% hauv 8-ntsis yog 16, thiab tus lej code rau 100% yog 235, yog li 50% yuav yog (16 + 235) / 2, uas yog 125.5. Feem ntau qhov no yog sib npaug rau 126, tab sis qhov tseeb yog qhov siab me ntsis. 125 yuav tsawg heev. 126 tiag tiag tawm mus rau 50.23%, uas yog qhov yuam kev tseem ceeb yog tias koj tab tom sim kom tau txais kev ntsuas qhov tseeb heev rau kev ntsuas qhov zoo. Hauv qhov sib piv, siv 10-ntsis code qhov tseem ceeb, koj tuaj yeem sawv cev raws nraim 50% raws li tus lej lej, txij li hauv 10-ntsis qhov ntau yog 64 940, thiab (64 + 940) / 2 = 502.

Thaum 50% tshwm sim los tawm zoo kawg nkaus hauv 10 khoom, 51% tsis ua, thiab tsis yog 52% lossis 53% lossis lwm tus lej tsuas yog 0% thiab 100%. Siv tag nrho 10 cov khoom txo qis qhov yuam kev ntau, tab sis yog tias koj lub hom phiaj yog kom ze rau qhov ua tau zoo, koj yeej xav thawb qhov yuam kev kom tsawg li sai tau, thiab qhov ntawd yog qhov twg dither tuaj.

Thaum lub teeb meter lossis colorimeter ntsuas lub qhov rais lossis thaj ntawm qhov screen, nws tsis ntsuas tus nqi ntawm ib lub pixel, nws ntsuas qhov nruab nrab ntawm ntau pua pixels uas txhua tus poob hauv nws lub voj voog ntsuas. Los ntawm kev sib txawv ntawm cov pixels nyob rau hauv lub voj voog ntsuas, peb tuaj yeem tsim cov txiaj ntsig zoo nrog qhov tsis txaus ntseeg. Piv txwv li, yog tias peb xav tau ib theem uas poob raws nraim ib nrab ntawm tus nqi code 10 thiab code tus nqi 11, peb tuaj yeem ua rau peb lub qhov rais ib qho kev sib cais ib nrab ntawm qhov pixels ib nrab ntawm code 10 thiab ib nrab ntawm code 11, uas yuav ntsuas raws nraim. ib nrab ntawm qhov ci ntsa iab xav tau rau code 10 thiab code 11. Tib yam siv rau qhov tseeb xim; los ntawm dithering ntawm cov xim sib txawv nyob ze peb tuaj yeem ntaus kom ze li ntawm lub cev ua tau kom muaj qhov sib tw tiag tiag rau cov xim peb xav kom pom.

Linear vs. Stimulus (% code tus nqi) Qib
Qhov no yog ib lub sij hawm zoo raws li ib qho kev paub qhov txawv ntawm ntau theem. Tej zaum koj yuav tau pom hauv peb cov qauv lossis pab cov ntawv nyeem uas tus qauv yog "50% code tus nqi" lossis "50% linear" thiab tshwj tsis yog tias koj muaj keeb kwm yav dhau hauv video lossis xim txoj kev xav nws yuav nyuaj rau nkag siab qhov txawv. Nov yog ib daim ntawv qhia ceev (heev) heev:

Nyob rau hauv zoo nkauj npaum li cas tag nrho cov ntaub ntawv ntawm cov duab thiab cov duab siv niaj hnub no, muaj ib yam dab tsi hu ua "hloov muaj nuj nqi" uas qhia cov tswv yim qhov tseem ceeb xa mus rau hauv cov zaub ("code lo lus" qhov tseem ceeb) rau qhov tseeb lub teeb uas yog lub cev tsim los ntawm cov zaub ( "linear" tus nqi). Nyob rau hauv Standard Dynamic Range (SDR) video, qhov hloov pauv muaj nuj nqi yog ib qho yooj yim zog nkhaus, qhov twg L = SG, qhov twg L yog linear Luminance, S yog tus nqi tsis-linear stimulus, thiab G yog gamma. Hauv HDR video, kev hloov pauv muaj nuj nqi ntau dua, tab sis nws tseem me ntsis zoo li qhov yooj yim zog nkhaus.

Kev hloov pauv muaj nuj nqi yog siv hauv kev kos duab vim tias nws qhia txog qhov pom ntawm tib neeg qhov muag pom kev pom ntawm cov kev hloov hauv lub teeb. Koj ob lub qhov muag muaj kev nkag siab ntau dua rau cov kev hloov hauv lub teeb ntawm qhov qis kawg ntawm qhov ci ntsa iab tshaj qhov kawg siab dua. Yog li los ntawm kev siv qhov nkhaus no los sawv cev rau theem teeb, cov duab encoded lossis yees duab tuaj yeem tso ntau tus lej ze ze ntawm cov xim dub, qhov chaw uas lawv xav tau, thiab tsawg dua nyob ze dawb, qhov twg lawv tsis xav tau ntau npaum li cas. Txhawm rau muab koj qee lub tswv yim ntawm qhov ntawd ua haujlwm li cas hauv kev xyaum, hauv 10-ntsis HDR encoding, mus los ntawm tus nqi code 64 txog 65 sawv cev rau kev hloov pauv hauv kab teeb theem ntawm 0.00000053%, thaum mus los ntawm tus nqi code 939 txog 940 sawv cev rau kev hloov pauv ntawm 1.085. %.

Yog tias qhov ntawd ua rau koj lub taub hau mob, tsis txhob txhawj, nws nyuaj me ntsis los qhwv koj lub taub hau ib ncig. Lub upshot yog hais tias, 25% stimulus tsis yog ib nrab li ci li 50% stimulus, yam tsawg kawg yog tsis nyob rau hauv lub cev units ntsuas los ntawm ib lub teeb meter. Tej zaum koj yuav pom, nyob ntawm qhov tseeb hloov pauv tau siv, uas 25% stimulus zoo li ib nrab li ci li 50% stimulus, vim hais tias yav tas los variations ntawm kev nkag siab ntawm tib neeg lub qhov muag, tab sis tib neeg lub qhov muag tsis ntsuas lub teeb. zoo li lub teeb meter.

Lwm qhov tseem ceeb uas yuav tsum paub yog tias nrog HDR niaj hnub no, nws muaj ntau dua los muab cov txiaj ntsig linear hauv cov luminance tag nrho, muab ua "candelas per meter squared" lossis "cd / m2". (Ib lub npe menyuam yaus rau chav tsev no yog "nits," yog li yog tias koj yuav tsum pom "1000 nits" uas yog luv luv rau "1000 cd / m2".)

Thaum saib cov lej cim hauv peb cov qauv, yog tias koj pom lo lus "linear" lossis pom tias cov units yog cd / m2, koj tuaj yeem ntseeg tau tias cov lej yog linear thiab sawv cev rau lub cev qhov ntau koj tuaj yeem ntsuas.

Yog tias koj pom cov lej muaj txiaj ntsig, lossis pom cov ntawv sau xws li "% code tus nqi" lossis "% stimulus" lossis txawm tias feem pua ​​​​tus nqi uas tsis muaj qhov tsim nyog, cov no yuav luag ib txwm txhawb nqa tus lej, uas tsis yog daim ntawv qhia linearly rau qhov ntsuas qhov ci ci.

Qhov sib txawv tseem ceeb ntawm cov no yog tias thaum koj muab ob npaug los yog ib nrab ib feem pua ​​​​ntawm cov txiaj ntsig lossis tus lej code, qhov ntsuas qhov ci tsis yog ob npaug lossis ib nrab, tab sis yuav hloov pauv raws li kev hloov pauv tam sim no. Thiab nrog kev hloov pauv HDR niaj hnub no, ob npaug ntawm qhov kev txhawb nqa tuaj yeem sawv cev ntau dua li ob npaug ntawm cov kab teeb ci, yog li koj qhov kev xav txog qhov ci ntsa iab yuav tsum txheeb ze rau lwm tus yuav tsis yog. Tsis txhob txhawj; qhov ntawd yog ib txwm ua rau cov neeg ua haujlwm nrog video txhua lub sijhawm.

Hauv qab no yog ib lub rooj uas qhia txog kev sib raug zoo ntawm linear light values ​​(in cd/m2), normalized linear percentage, stimulus percentage, and the nearest code value in 10-bit limit-range encoding. Tag nrho cov no suav tias yog ST 2084 kev hloov pauv kev ua haujlwm, kev ua haujlwm siv los ntawm HDR encoding niaj hnub no.
