S / PDIF - chii?

Nhasi, kune cheap car insurance zhinji kudaro, uye connectors kuti dzimwe nguva zvakaoma kubata mumwe wavo. Somuenzaniso, kazhinji pane matambudziko kutengwa devaysa itsva uye batanidza kwachiri chero mamwe mazano. Nhasi tichadzidza zvose pamusoro S / PDIF - ndiko kuti, nokuti chii uye nei.

pfungwa

Zvinofadza kuti mureza dzakawanda zvinogona kushandiswa senzira musiyano pakati S / PDIF, uye S / PDIF. Ndiye kupa decoding kwayo, izvo zvinoita kuti tikwanise kunzwisisa chii mureza yakazokudziridzwa. Sony / Philips Digital inowanikwa Format anochengetedza kutaridza dzakati parameters kuti Hardware Implementation. It anokwanisa kubvisa digitaalinen ekuteerera kubva Audio mudziyo wokutanga wechipiri.

Uchifunga S / PDIF, tigokuitira nawo uye kwomuviri chikamu hurongwa. pfuma Mumuviri zvinoita kuti tikwanise kuziva nzira chiratidzo iri inoparadzirwa uye kuburikidza iyo mugero, uye hurongwa - yacho dzakati kushandiswa.

Specification

Tisati taongorora kukura kwebasa inowanikwa ichi, tinoona kuti zvaakanga achiita. Kazhinji, youduku ichi rinobvumira mhando inoverengeka netambo uye connectors. Saka nyika iripo digital S / PDIF, coaxial uye Manyiminya. Pane nzira dzose idzi pasi adapters uye adapteri zvakakodzera. Pamwe pane imwe coaxial Manyiminya kushandiswa, uye vakutarisire. Chinhu bedzi, kuwedzera kune adapters inoda kwokunze simba zvitengeswa.

baba

Kukura inowanikwa iri rakatanga raivapo panguva iyoyo nyanzvi AES / EBU mureza. Cipher akatanga kuzivikanwa muna 1986. Zvadaro takashanda pairi Company mainjiniya uye European Broadcasting Union. The Ruramiswa shanduro yakashandiswa muna 1992, uye ipapo akatsungirira kuchinja muna 2002 uye 2009.

Senguva dzose, pane musiyano pakati interfaces. Inogona tsunga kushandisa zvakanaka-mitemo.

musiyano

Kana usingazivi chavanoziva pamusoro S / PDIF, uye zviri zvaunoda, iwe zvichida havasati vanzwa uye AES / EBU. Ichangobva mureza yakagadzirwa kuti dat uye CD zvinogona, izvo encoded kushandisa zvechivhurumukira-bumbiro vachisiyanisa inzwi. Inowanikwa anoshandisa BMC romutemo. Izvi zvinoreva kuti kuchinjwa mashoko kunoitika chero exponent zvakabudiswa kakawanda, uye kakawanda nokupora Data inopfuura nomunyika decoding.

AES mureza Aimiririrwa okunatsiridza matatu. All akashanda 110 ohms nemishonga indekisi ane symmetric kubatana, zvichienderana okunatsiridza anoshandiswa Cable kudzivirirwa peya kana chikamu 5. In iyi uyewo siyana mwero connectors, chokutanga XLR kana D-25, RJ-45 gare gare. The chiratidzo pamwero 2-7 V.

Kusiyanisa inzwi kumbochinja uye vakayambuka yeEncoding. Subcode date ndiyo ASCII ID-chinyorwa. The kunonyanyisa kure pakutanga raiva 100m chete gare gare - 400 M Resolution yakasvika 24 matomu..

Tisati tose vakadzidza pamusoro S / PDIF, uye zviri sei uchifanira, paiva zvenguva nezvechisarudzo AES3id. Wakabata pamwechete 75 Ohm, kubatana akanga kunyanyisa coaxial waya. Connector nemanyorerwo achinja zvakare kuna BNC, uye chiratidzo pamwero aregedza 1 V. The kunonyanyisa mufambo kwasvika pfungwa 1000 M kugadzirisa simba inoramba chete -. 24 matomu.

Izvi zvokungoitawo shanduro dzinongoita dzinofanira Specification zvinhu zvitsva. Somuenzaniso, ari kuongororwa mitemo vakamboshanda 75 Ohm, kudzikama kubatana ane. Coaxial waya ndiye zvose, uye Manyiminya, zvichienderana nemhando. Connector achinja zvakare youduku: rca kana TOSLINK. Chiratidzo pamwero yava shoma pane hafu - 0.5 V. achinja subcode Data kuti vakagadzirira rakachengeteka michina kubva SCMS kopi. Kunonyanyisa kureba kunoderedza uye vakava chete 10 m, uye 20 matomu optioneel kugona akaratidza zvose zvakafanana 24 nematomhu.

mhando

Sezvo yapfuura isu akati, kune mhando nhatu neezvitendero ichi. Pane Manyiminya S / PDIF, digitaalinen uye coaxial. TOSLINK kutanga akamuka ayo anoonga zita kuna Toshiba yokuvaka. Izvi faibha-optic mureza. Aigona kakawanda kuwanikwa mudzimba makaseti mano, kombiyuta ruzha makadhi, uye zvichingodaro. D. A nevakawanda ichangobva kuva MiniTOSLINK chimiro chinhu 3,5 Jack. Vanogona kuwanika mamwe yemashoko Laptops, ane S / PDIF dzichienderana ine headset goho.

Coaxial mhando ine nemishonga ine 75 ohms, hwakabatana pamwe rca inowanikwa. Kana musingadi anonyatsoenderana kwakajairika okuteerera netambo, aizivikanwawo tulips, zvino kutarisa coaxial mureza. Kushanda nemazvo, zvinonzi wakagumiswa kumativi ose, uye mabasa mazano uye goho impedance pamusoro 75 ohms.

Digital Audio S / PDIF - chetatu mhando Level (TTL). Mureza inobva Zano kuvaka nedambudziko transistors uye resistors. Transistor-transistor pfungwa dzinobva muzvikamu zviviri, kunyange nguva dzose. Home> 2.4 V, wechipiri 0-0.4 V. The outputs izvi mhando inogona kuwanika inzwi nemakadhi.

Pane nyore tsanangudzo kupatsanura, kudzivisa kuvhiringidzika uye zvakakodzera kubata chokwadi kuti - S / PDIF. Izvi digitaalinen Audio inowanikwa, sezvatakagamuchira zvakwakafukurwa, angava digital kana Manyiminya. Kana Hamubvumirwi rakanaka musha Audio hurongwa kana inzwi pakati, zviri nani kubatanidza nayo Via ichi connector mhando. Kurira Unhu iri nani zvikuru kupfuura mwero format.

Improvement nokuti kuti kurira ichipfuura mukuru-kakawanda zvekupfakira nekunhonga ose "tsvina" pulses goho kuburikidza analoginen pamanyorerwo uye digitaalinen chisingazivi Unonzwa akavhiringika. Kana ukashandisa Manyiminya mwero, unogona kukanganwa pamusoro ruzha zvinowanzoitwa tikachirega.

kunyoresa

Kufuratirwa mureza wokutanga kushandiswa CD-vatambi. Pashure takawana kuti rinogona kushandiswa senzwi wokutepfenyurisa uye connector mune dzimwe zvakarekodhwa mudziyo. Saka, inowanikwa iri azviise MiniDisc-vatambi uye ruzha makadhi nokuda PC. Vamwe vatyairi kucherechedza anogona mureza motokari Audio. Kunyanya yava godsend vaya waneta marara ose vakawanda netambo. Zvino svinga waya hunogona kungoparara kutsiviwa nemumwe internet optic waya.

S / PDIF anogona kuwanikwa sezvo digital rukova wokutepfenyurisa. Kazhinji pane nzira iyi inoshanda ne DVD-mutambi chiyamuro AV-musha theatre receiver. Somugumisiro, vose itsva inzwi michina dzawanika pamba. vanozvishandisa zhinji vanokwanisa tinyatsoziva Dolby Digital uye Digital Theater System (DTS).

Vose zvokusarudza, vakawanda connector akava rca. Ari aiwanzopiwa wokushanda pamwe S / PDIF "riri" iri nevatengi Audio michina mureza. A zvishoma ane Manyiminya mhando rinoshandiswa zvishoma kakawanda. Kushandisa gudzanzwi nokuva acoustic zvakakodzera chete kuwana zvibereko S / PDIF.
