Ukukhanga okuyinhloko kwezimpahla zendawo yaseshashalazini kubathengi abaningi yikhono lokunikeza isipiliyoni esizwakalayo sokulalela.

Lezi zinsuku, ngisho nezamukeli ezisemqoka kakhulu zaseshashalazini zasendlini zinikeza izinketho eziningana, kuhlanganise hhayi kuphela ukumemezela ukucaciswa kweDolby Digital ne- DTS Digital Surround , kepha i-Dolby TrueHD ne- DTS-HD ye-Master Audio yokucubungula (okuyinto amafomethi oyinhloko asetshenziswa kuma-Blu-ray Discs ), kanye (kuye ngokuthi umkhiqizi) amafomethi okucubungula okuzungezile okungeziwe.

Futhi, njengoba uhamba phakathi nendawo ephakathi nendawo ephezulu ye-receiver reception models, amafomu ezansi azungezile njengeDolby Atmos , i- DTS: X , noma ngisho ne- Auro3D ingavunyelwa noma ihlinzekwe njengendlela ongakhetha ngayo. Noma kunjalo, i-DTS: X ne-Auro3D Audio ngokuvamile idinga isibuyekezo se-firmware.

Ngaphezu kwalokho, qaphela ukuthi ukufakwa kwamafomethi ahlukahlukene okuzungezile kuzama futhi ukuthi zingaki iziteshi umamukeli wendawo yaseshashalazini angahlomele - okungahle kube khona okungenani kusuka ku-5 kuya kwezingu-11.

Isethaphu yeSomlomo esenzekelayo

Yize kungenjalo njalo kufakiwe emitholampilo engabizi kakhulu yaseshashalazini yasendlini, cishe wonke uhla lwaphakathi nendawo nabasamukelayo bezindawo zasendlini ephezulu ekuhlinzekeni isistimu yokusetha isiphakamiso esakhelwe ngokuzenzakalelayo esebenzisa isakhi se-tone yokuhlola esakhelwe ngaphakathi kanye nemakrofoni e-plug-in ekhethekile.

Ukusebenzisa la mathuluzi, indawo yaseshashalazini yaseshashalazini ingakwazi ukulinganisela amazinga esipikha ngokuhambisana nosayizi wesipikha, ibanga, kanye ne-acoustics ekamelweni. Ngokuya kulolu hlobo, lezi zinhlelo zinegama elihlukile njenge-AccuEQ (Onkyo), i-Anthem Room Correction (Anthem AV), i-Audyssey (i-Denon / Marantz), i-MCACC (Pioneer), ne-YPAO (i-Yamaha).

Ukuxhumana

Bonke abamukeli bemidlalo yaseshashalazini banikeza ukuxhumeka kwesikhulumi, kanye nokukhishwa okhethekile kokuxhumeka kweyodwa, noma ngaphezulu kwe- subwoofers , nezinketho eziningana zokuxhumeka komsindo ezifaka phakathi i- analog stereo , i- coaxial digital, ne-digital optical , nezinketho zokuxhumeka kwevidiyo okungase zihlanganise ividiyo ehlanganisiwe neyomculo . Noma kunjalo, izinketho ezihlanganisiwe / izingxenye zitholakala kancane kulabo abamukeli bomnyaka ngamunye olandelanayo ngenxa yokusetshenziswa okuqhubekayo kwe-HDMI, okuxoxwa ngayo ngokuningiliziwe okulandelayo.

I-HDMI

Ngaphandle kokukhethwa kokuxhumana okukhulunywe ngakho ngenhla, ukuxhumeka kwe-HDMI kunikezwa kuwo wonke ama-receiver asekhaya asekhaya. I-HDMI ingadlulisa kokubili amarekhodi alalelwayo namavidiyo ngekhebula elilodwa. Nokho, kuye ngokuthi i-HDMI ifakiwe kanjani, ukufinyelela kwamakhono we-HDMI kunganciphisa.

Abamukeli abaningi abanamanani aphansi bafaka ukuguqulwa kwe-HDMI ukudlula. Lokhu kuvumela ukuxhumeka kwezingcingo ze-HDMI ku-receiver futhi kunikeza uxhumano lwe-HDMI lokukhishwa kwe-TV. Noma kunjalo, umamukeli akakwazi ukufinyelela izingxenye zevidiyo noma zomsindo wesignali ye-HDMI ukuze kusetshenzwe okuqhubekayo.

Abanye abamukelayo bafinyelela kokubili izingxenye zomsindo nevidiyo zezimpawu ze-HDMI ukuze ziqhutshwe phambili.

Futhi, uma uhlela ukusebenzisa isidlali se-3D TV ne-3D Blu-ray Disc ne-receiver yakho yaseshashalazini, khumbula ukuthi umamukeli wakho kufanele afakwe i- HDMI ver 1.4a yokuxhumana. Uma unemidlalo yaseshashalazini engenalo lelo khono, kunomsebenzi wokusebenza ongakusebenzela .

Kumele futhi kuqaphele ukuthi i-HDMI 1.4 ne-1.4a yokuxhumeka nayo inamandla okudlula izimpawu zevidiyo ezingu- 4K (30fps), uma ngabe lesi sici senziwe ngumenzi we-receiver.

Noma kunjalo, kusukela ngo-2015, abamukelayo yaseshashalazini basekhaya basebenzise ukuxhumana kwe-HDMI okunamathela kumazinga we-HDMI 1.4 / 4a kanye namazinga we-HDMI 2.0 / 2.0a nama-HDCP 2.2. Lokhu kuzokufaka izimpawu ezingu-4K ku-60fps, kanye nokukwazi ukwamukela izimpawu ezine-4K ezivikelwe emithonjeni yokusakaza kanye nefomethi ye - 4K Ultra HD Blu-ray Disc , kanye nemithombo efaka okuqukethwe kwevidiyo ye-HDR .

Enye inketho yokuxhumanisa ye-HDMI etholakala kwamamukeli athile wezemidlalo yi- HDMI-MHL . Lokhu kuxhumene kwe-HDMI kungenza konke ukuxhumeka "okuvamile" kwe-HDMI kungakwazi, kodwa kunekhono elingeziwe lokubhekana nokuxhumeka kwama-smartphone namaphilisi anikwe amandla we-MHL. Lokhu kwenza umamukeli ukuthi afinyelele okuqukethwe okugcinwe noma okusakazwa kumadivayisi, okuphathekayo, ukubuka noma ukulalela ngokusebenzisa uhlelo lwakho lokudlala yaseshashalazini. Uma i-receiver yakho yaseshashalazini yasendlini inokufaka i-MHL-HDMI, izobe ibhalwe ngokucacile.

I-Multi-Zone Audio

I-Multi-Zone ingumsebenzi lapho umamukeli angathumela isignali yesibili yomthombo kuzikhulumi noma isistimu yomsindo ohlukile kwenye indawo. Lokhu akufani nokuxhuma izipikha ezengeziwe futhi uzibeke kwelinye igumbi.

Umsebenzi we-Multi-Zone uvumela iReceiver yasekhaya yasekhaya ukuthi ilawule okufanayo noma ehlukile, umthombo kunalowo olalelwa ekamelweni elikhulu, kwenye indawo. Isibonelo, umsebenzisi angabuka i-Blu-ray Disc noma i-DVD egumbini elikhulu, kanti omunye umuntu angalalela i-CD kwenye, ngesikhathi esifanayo. Kokubili i-Blu-ray noma iDVD noma i-CD player ilawulwa yiReceiver efanayo.

Qaphela: Abanye abamukeli bezindawo zaseshashalazini eziphakeme kakhulu baphinde bafake iziphumo ezimbili noma ezintathu ze-HDMI. Kuye ngomamukeli, imiphumela eminingi ye-HDMI inganikeza isignali yomsindo / yevidiyo efanayo kwezinye izindawo noma ingalungiswa ngokuzimela ukuze umthombo owodwa we-HDMI ungatholakala ekamelweni elikhulu futhi umthombo wesibili we-HDMI ungathunyelwa kumzuzwana wesibili noma I-Zone yesithathu.

I-Multi-Room engenazintambo / Indlu Ephelele Yomsindo

Ngaphandle kokhetho lwendabuko lwama-multi-zone, ezinye izimpendulo zendawo yaseshashalazini nazo zinikeza ikhono lokusakaza umsindo ngaphandle kwezingcingo ezingenazintambo ezixhunywe nge-inthanethi ekhaya. Noma kunjalo, umkhiqizo ngamunye unesistimu yawo evaliwe efuna ukusebenzisa imikhiqizo ethile ehambisana nomkhiqizo.

Ezinye izibonelo zifaka: Umculo we-YamahaCast , FireConnect kusuka ku-Onkyo / Integra / Pioneer, i-HEON ye-HEOS, ne-DTS Play-Fi (i-Anthem)

iPod / iPhone Ukuxhumana / Ukulawula ne-Bluetooth

Ngokuthandwa kwe-iPod ne-iPhone, abanye abamukelayo banezixhumi ezihambisanayo ze-iPod / iPod, noma nge-USB, ikhebula le-adapter, noma "isiteshi sokukhokha". Okufanele ubheke akuyona kuphela ikhono le-iPod noma i-iPhone ukuxhuma kumamukeli kodwa kumamukeli ukulawula empeleni yonke imisebenzi ye-iPod yokudlala ngokulawula okude nokutholwa kwemisebenzi.

Kanti futhi, abaningi abamukelayo yaseshashalazini basekhaya bafaka amandla e-Apple Airplay akhiwe ngaphakathi, okuqeda isidingo sokuxhuma i-iPhone kumuntu owamukelayo, ungahlala futhi uthumele i-iTunes yakho kumamukeli wendawo yaseshashalazini.

Futhi, khumbula ukuthi uma uxhuma iPod Video, ungafinyelela kuphela kwimisebenzi yokudlala. Uma ufisa ukufinyelela emisebenzini yokudlala ye-iPod, hlola incwadi yomsebenzisi yomamukeli ngaphambi kokuthenga ukuze ubone ukuthi lokhu kungenzeka.

Esinye isengezo esitholakale kumamukeli amaningi yaseshashalazini ekhaya yi-Bluetooth. Lokhu kuvumela abasebenzisi ukuthi basakaze amafayela alalelwayo ngqo kusuka kudivayisi ephathekayo ephathekayo ene-Bluetooth ehambisanayo.

Ukuxhuma kwe-Inthanethi / I-Inthanethi / Ividiyo

Ukuxhumeka kwenethiwekhi kuyisici esitholwa ngabamkeli abaningi baseshashalazini basekhaya, ikakhulukazi endaweni yezinga eliphezulu. Izingosi zenziwa nge-Ethernet uxhumano noma i-WiFi.

Lokhu kungavumela amandla amaningana okufanele uwahlole. Akuzona zonke izimpendulo zokuxhumana ezinamakhono afanayo, kepha ezinye izici ezivame ukufakwa zilandelayo: Ukusakaza umsindo (futhi ngezinye izikhathi ividiyo) kusuka ku-PC noma i-intanethi, umsakazo we-inthanethi, kanye ne-firmware evuselela ngokuqondile kwi-intanethi. Ukuze uthole ukuthi izici zokuxhumanisa kanye / noma ukusakaza zifakiwe kumamukeli othile, hlola incwadi yomsebenzisi, ishidi lesici, noma isibuyekezo ngaphambi kwesikhathi.

I-Hi-Res Audio

Enye inketho etholakalayo ngenani elikhulayo labalamukeli bezemidlalo yikhono lokufinyelela nokudlala amafayela womsindo we-Hi-res alalelwayo amabili.

Kusukela ukufakwa kwe-iPod namanye amadivaysi okulalela okuphathekayo, nakuba ukwenza ukufinyelela komculo kube lula kakhulu, basuke basithatha emuva ngokwemibandela esiyixazulula njengomculo omuhle wokulalelwayo womculo - ikhwalithi idonswa yiyo yendabuko I-CD.

Leli gama, i-Hi-Res yomsindo isetshenziselwa kunoma yiliphi ifayela lomculo eline-bitrate ephakeme kune-CD engokwenyama (i-16 bit line- PCM eqondile esilinganisweni se-44.1khz sampling).

Ngamanye amazwi, noma yini engezansi "ikhwalithi ye-CD", njenge-MP3 namanye amafomethi agxilile kakhulu kubhekwa njengomsindo ophansi ", futhi noma yini engaphezulu" kwekhwalithi ye-CD "ibhekwa" umsindo we-res ".

Amanye amafomethi amafayela abhekwa njengama-res; ALAC , FLAC , AIFF, WAV , DSD (i-DSF ne-DFF).

Amafayela we-Hi-Res alalelwayo angatholakala nge-USB, inethiwekhi yasemakhaya, noma ilandelwe kusuka ku-intanethi. Ngokuvamile abakwazi ukusakaza bukhoma ngokuqondile kusuka ku-intanethi - Noma kunjalo, kukhona ukunyakaza okuvela kumasevisi, njenge-Qobuz (ayitholakali e-US) ukuhlinzeka lokhu ngamakholi e-Android. Uma isamukeli esithile sekhaya yaseshashalazini sinalo ikhono, lizobe libhalwa ngaphandle kwesikhangiso noma lichazwe kumbhalo womsebenzisi.

Ukushintshwa kwamavidiyo nokucubungula

Ngaphandle kokulalelwayo, esinye isici esibalulekile emitholampilo yaseshashalazini yendawo ukufakwa kwevidiyo ukushintsha nokucubungula.
