S / PDIF - he aha te mea te reira?

I teie mahana, i reira e pera maha i'ai, me tūhono e e te tahi mau taime fifi ki te mahi ki tetahi o ratou. Hei tauira, i reira e maha raruraru ki te hoko o te devaysa hou, me te hono atu ki reira tetahi atu pūrere. I teie mahana, e ako tatou katoa e pā ana ki te S / PDIF - e ko te, hoki te mea, me te aha.

ariā

Ko reira ngā e taea te whakamahi i te paerewa ao rite te kē o S / PDIF, ko S / PDIF. Ko ia tapae tona wetemuna, e āhei ai ia tatou ki te matau te mea i whakawhanakehia te paerewa. Hōputu Atanga Digital Sony / Philips pupuri te huinga o ngā tawhā kawa ki te whakatinanatanga pūmārō. He te kaha ki te whakawhiti ororongo mamati i te pūrere ororongo tuatahi ki te tuarua.

Whakaaro i te S / PDIF, ka mahi matou ki a reira, me te wahi tinana o te pūnaha. hanga taonga tinana reira taea ki te mohio e ara tuku te tohu kei te me i roto i nei takere, me te pūnaha - te kawa whakamahia.

whakatakotoranga

I mua i ui i te hōkai o tenei atanga, ite tatou te mea i mahi ia. I roto i te whānui, i tenei hōputu taea hoki te maha ngā momo o taura me tūhono. Na te ao he wātea he S mamati / PDIF, tafenga me te whatu. He enei kōwhiringa katoa i raro i te whāurutau tika, me te whāurutau. Pea hei utu o te whakamahi whatu tafenga, a hurihia. Ko te mea anake e, i roto i te tua ki te whāurutau rapu he supply mana waho.

papa

timata te whanaketanga o tenei atanga ki reira ngā paerewa AES / EBU ngaio. tuatahi ka Kaituhi mohiotia i roto i 1986. Na ka mahi matou ki runga i te reira i te Engineers Kamupene me te Pākehā Broadcasting Union. whakamahia te putanga papaki i roto i 1992, a ka whakamanawanui te huringa i roto i te 2002 me te 2009.

I mua, i reira he he rerekētanga i roto i te atanga. Ka taea te whakaritea te reira i te whakamahi i te pai-whakapumautia paerewa.

rerekētanga

Ki te kahore koe e mohio ki tetahi mea e pā ana ki te S / PDIF, a te reira te mea e hiahia ana koe, koutou pea kua kore rongo o me AES / EBU. Ko te paerewa hou whakaaro mō hōputu dat ko CD, e kua whakawaeheretia te whakamahi i te puoro hihiko-waehere. Ka whakamahi te atanga BMC waehere. Tenei te tikanga e puta i te whakawhitinga o te mōhiohio ki tetahi auau taupū tīpako, ka haere te raraunga auau whakaora i roto i te wetewaehere.

i māngai paerewa AES e toru akatuke'anga. mahi katoa ki 110 ohms ātete taupū ki te hononga hangarite, i runga i nga whakarerekētanga whakamahia rānei Cable paruruhia rua kāwai 5. ranei I roto i tenei take hoki rerekē tūhono paerewa, XLR tuatahi D-25, RJ-45 i muri mai ranei. Ko te taumata tohu o 2-7 V.

noho tonu puoro, a haere i roto i te whakawaehere. Subcode raraunga Ko ASCII ID-kuputuhi. Te tawhiti mōrahi i te tuatahi ko anake 100m i muri - 400 m tae Resolution 24 paraire..

I mua i ako matou katoa e pā ana ki te S / PDIF, a te reira he aha e hiahia ana koe ki te, i reira ko te kōwhiringa takawaenga AES3id. Kua mahi ia ki 75 Ohm, i hononga taura tafenga porangi. ke ano hōputu tūhono ki BNC, a kua maturuturu iho te taumata tohu ki 1 V. Kua tae te tawhiti mōrahi he wāhi 1000 m te mana whakatau tonu te taua -. 24 paraire.

Kei te nuinga o tēnei putanga wā mangai te whakatakotoranga o ngā tūemi hou. Hei tauira, mahi hoki nga paerewa aroturukitia ki 75 Ohm, he hononga porangi. Ko e rua, me optical taura tafenga, i runga i te momo rānei. ke ano Tūhono hōputu: RCA TOSLINK ranei. hei taumata Tohu kua iti iho i te hawhe - 0.5 V. ke subcode raraunga rawa e te ki te hangarau haumaru i SCMS kape. heke roa mōrahi me ka anake 10 m, me 20 paraire whakakitea kaha kōwhiringa nga taua 24 paraire katoa.

momo

Ka rite mea matou mua, i reira e toru ngā momo o tenei paerewa. He he he S whatu / PDIF, mamati me tafenga. ka tuatahi TOSLINK tona ingoa whakawhetai ki Toshiba kaiwhakawhanake. Tenei paerewa muka-whatu. maha i kitea ia i roto i ngā pūrere kāinga oro, kāri tangi rorohiko, a na i runga i. D. He puka tauwehe MiniTOSLINK tata riro rongonui 3,5 Jack. Ka taea te kitea ratou i runga i te tahi mau tauira o rorohiko, tona S / PDIF hāngai ki te putanga pane.

momo tafenga he ātete o 75 ohms, te hono ki atanga RCA. Ki te kore koe e pai te taura ororongo tikanga, ano e mohiotia ana ko te tulip, ka titiro ki te paerewa tafenga. Hei mahi tika, kua poroa te reira i runga i ngā taha e rua, me te mahi o te kōkuhu me te whakaputa parenga ia o 75 ohms.

Digital audio S / PDIF - he momo toru o te Taumata (TTL). E hāngai ana te paerewa i runga i te kaupapa o te hanga o nga transistors pourua me parenga. hāngai ana transistor-transistor arorau runga rua ngā wāhanga, ahakoa e kore e tonu. Kāinga> 2.4 V, te tuarua 0-0.4 V. nga ngä o tenei momo e taea te kitea i runga i ngā kāri tangi.

He he he whakamārama ohie o te whakarōpūtanga, ki te karo whakama, me te tika mahi ki te meka i he reira - S / PDIF. Tenei atanga ororongo mamati, rite kua kitea e matou, kia waiho hei mamati whatu ranei. Ki te mea kua whakairi koe i te pūnaha kāinga audio pai pokapū tangi ranei, he pai ki te hono i te reira mā tenei momo tūhono. Ko te nui, pai atu i te hōputu paerewa te kounga tangi.

Improvement tika ki te meka e haere te tangi i roto i te whakakī tiketike-auau, me te kohikohi i te "paru" ngātere putanga katoa i roto i te hōputu tairitenga me mamati, e kore e pūmau e fakakehei. Ki te whakamahi koe i te paerewa whatu, ka taea e koe wareware e pā ana ki te haruru o te puku noa.

tono

paerewa wareware whakamahia tuatahi i roto i te CD-kaitākaro. I muri i kitea e matou e taea te whakamahi i te reira rite te tuku tangi me te tūhono i roto i te tahi atu pūrere ororongo. Na, tenei atanga ko ki puta i roto i te MiniDisc-kaitākaro me kāri tangi mo te PC. Ka taea e kite ētahi taraiwa fakatokanga te paerewa i roto i te oro motokā. Rawa kua reira he pepeé mo te hunga e ngenge o te taputapu o te maha nui o ngā taura. Na e taea te ngāwari whakakapi te paihere o waea ki tetahi muka whatu taura.

S / PDIF taea te kitea ano he tuku awa mamati. Tikanga i roto i tenei aratau mahi ki tāuru DVD-kaitākaro AV-home whakaari kaiwhiwhi. Ka rite ki te hua, ka wātea hangarau tangi hou katoa i roto i te kāinga. He maha ngā kaiwhakamahi e taea ki te kia kite ia Dolby Digital me Digital Theatre Pūnaha (DTS).

O nga kōwhiringa katoa, ka te tūhono tino noa RCA. Kei te takirua ia ki S / PDIF "Kei" i roto i te kiritaki paerewa taputapu ororongo. whakamahia te moka o te momo whatu te iti auau. Hei whakamahi i te pūnaha tangi ki acoustic hohe tika noa ki te tiki i te tukua o S / PDIF.
