Izinkinga eziyisithupha ezinkulu kakhulu nge-HD Radio
Njengoba kuphela umsakazo we-digital yomsakazo wedijithali ovunyelwe ukusetshenziswa e-United States yi-FCC, i- HD Radio ifinyelele okuningi ukungena emakethe kusukela isiteshi sokuqala sahamba ngedijithali ngonyaka ka-2003. Ukuthola ubuchwepheshe emotweni nge-OEMs buhlakani ukuhamba, ucabange ukuthi ingxenye enkulu yomsakazo ulalele izilaleli ezilalela kuphela ngenkathi ihamba ngesondo, kodwa umgwaqo usuke ungaphenduki eminyakeni edlule.
Nakuba amaphesenti amakhulu abanikazi bamoto abasha abane-HD Radios, inamba esabekayo yabo abazi-mhlawumbe banakekelwa-ukuthi lokho kusho ukuthini. Futhi noma ngabe zenzani, ukulinganiselwa okungokwemvelo kwefomathi, okuhambisana nezinkinga ezihlobene nezinto zangempela zebhizinisi le-radio yokusakaza, kusho ukuthi i-HD Radio ayisebenzi njalo njengoba ikhangiswa. Ngakho-ke ngenkathi kuthiwa ukuthi ifomethi ifile, noma ifile, kungenzeka ingabi yiqiniso ngokuphelele , nayizinkinga eziyisithupha ezinkulu kakhulu nge-HD yomsakazo namuhla:

Ukwamukelwa Kuye Kwadlula
Ukuphumula kuyisikhathi esivumelanayo, ukuqinisekisa ukuthi, futhi iBiquity iye yenzeke ngokuvumelana nesisekelo sokuthenga umthengi. Ngokwesibonelo, enye yezimoto ezintsha ezintathu ezithengiswa ngo-2013 yayihlanganisa i-HD Radio tuner. Kodwa-ke, lokho kushiya izimoto ezindala ezihamba phambili ezihamba phambili zineziteshi zama-analog futhi azikho isizathu esicindezelayo sokushintsha, ikakhulukazi ngezinketho ezifana nomsakazo we-inthanethi etholakalayo. Njengoba kuqhathaniswa ngokuqondile kwalaba ababili, ngo-2012 cishe amaphesenti angama-34 aseMelika abika umsakazo we-intanethi wokulalela-kuhlanganisa kokubili izinhlelo ezifana nePandora kanye nemifudlana e-intanethi yeziteshi ze-AM ne-FM- uma kuqhathaniswa nama-2 amaphesenti abike ukuthi alalele i-HD Radio.
Ukukhishwa okukhulu kunesilinganiso sokutholwa sobuchwepheshe bokusakazwa kwe-HD Radio, ngoba awukwazi ngisho nokusebenzisa i-HD Radio akekho osebenzisa ubuchwepheshe ukusakaza isignali yedijithali. Nakuba inani lezikhungo ezifake i-tech landa kancane phakathi kuka-2003 no-2006, iziteshi ezimbalwa zenze ushintsho unyaka ngamunye kusukela ngaleso sikhathi. Uma uhlala endaweni enezindaba ezinhle ze-HD, ngakho-ke akuyona inkinga. Kulabo abahlala ezindaweni ezikhonjwe ngeziteshi ezimbalwa, noma cha, i-HD Radio, ubuchwepheshe kungenzeka ukuthi abukho.

Ama-OEMs Angayishiya Imisakazo Yonke
Ngesinye isikhathi, ukubhala kwakubonakala kunodongeni lwezinsimbi zomsakazo ezifakwe efinini, kungaba i-analog noma i-digital. Abakwa-automakers abaningana bebikwe ukuthi bazinikele ekususeni umsakazo we-AM / FM, ne-HD Radio ngommeli, kusuka kuma-dashibhodi abo ngo-2014. Lokho akuzange kwenzeke, futhi umsakazo wemoto ubonakala uthola ukuhlala, kepha isithombe sisese udaka.
Imboni yomsakazo kanye ne-iBiquity, ikakhulukazi, kuthiwa isebenza nabakhi bezimoto ezinkulu ukugcina ama-radio tuners kuma-stereos emoto ye-OEM, kepha uma amagama amakhulu embonini yezimoto anquma ukuhamba ngenye indlela, kungaba yi-HD Radio .

Ukusakazwa kwe-HD ye-HD kungaphumelela ngezindawo eziseduze
Ngenxa yokuthi ubuchwepheshe be-iBiquity obuku-band-on-channel (IBOC) busebenza, iziteshi ezikhetha ukusebenzisa i-tech ngokuyisisekelo zithumela ukusabalalisa kwazo kokuqala nge-digital "amabhande amaceleni" ngezansi kanye nenhla yezintambo zabo ezibekiwe. Uma amandla anikezwe ngamabhande ohlangothini ephakeme ngokwanele, angakwazi ukuphuma emigwaqweni eseduze eduze kwama-frequencies ngokushesha ngenhla nangaphansi kwesiteshi esisebenzisa i-IBOC. Lokhu kungabangela ukuphazanyiswa ukubhubhisa isipiliyoni sokulalela kwanoma ubani ozama ukungena kulezo ziteshi.

Ukusakazwa kwe-HD ye-HD kungadlulela ngohlelo lwabo lwe-Analog Broadcast
Ngendlela efanayo namabhande amaceleni edijithali angakwazi ukungena emagcekeni aseduze futhi abangele ukuphazanyiswa, angaphinde aphazamise isignali yabo ehambisanayo ye-analog. Lena inkinga enkulu kakhulu uma kwenzeka kusukela enye yezinto ezibaluleke kakhulu zokuthengisa ze-IBOC ukuthi ivumela izibonakaliso zedijithali ne-analog ukuthi zihlanganyele imvamisa efanayo eyake yenziwa kuphela ngesignali ye-analog. Kuyinto futhi uhlobo lokubamba-22 ngenxa yokuthi amandla esignali aphansi aphumela ekusakazweni kwe-HD okungekho muntu ongayithola, kuyilapho oqinile engaphazamisa isignali ye-analog, okuwukuthi cishe wonke umuntu ulalele ngempela kuya endaweni yokuqala.

Akekho owaziyo ukuthi i-HD Radio iyini
Lokhu kusobala ukuthi i-hyperbole, kodwa inani elimangalisa labantu abawazi ngempela ukuthi yi-HD Radio, liyifaka ngomsakazo we-satellites , noma nje ithafa alinaso isithakazelo. Phakathi ne-push yokuqala ukuze uthole ubuchwepheshe bufakwe eziteshini zomsakazo nasezandleni zabathengi, isithakazelo asizange siphume ngaphezu kwamaphesenti angu-8.
Lokhu kuhle kakhulu uma ucabanga ukuthi imboni yomsakazo ngokwayo ibhekene nokukhula okulinganiselwe ngasekupheleni kwaleyo nkathi, naphezu kokuncintisana okuqinile okukhethwa kukho njengomsakazo we-inthanethi nokunye okuqukethwe kwe-intanethi. Yiqiniso, mhlawumbe isizathu sokuntuleka kwesithakazelo:

Akekho Oceliwe I-HD Radio
Ukubanda, iqiniso eliqinile ukuthi i-HD Radio ifomethi ekufuneni izethameli ezingazange zicele kuqala. Ngezinye izikhathi, ukucabangela izilaleli ngaphambi kokuba kutholakale kubangele inzuzo yokuncintisana, futhi osomabhizinisi abakwazi ukwenza lesi simangaliso encane bavame ukukhulunywa njengabahlakaniphile.
Futhi esimweni se-HD Radio, ngesigwebo se-FCC, kubonakala sengathi wonke amakhadi e-iBiquity ayesendaweni ukuze akhiphe ukukhishwa okukhulu ngokufaka imali emakethe emisha enkulu. Kodwa eminyakeni edlulile kusukela i-IBOC ivunyelwe njenge-sole yedijithali yomsakazo we-digital e-United States, izinto azikazanga ukuphuma ngaleyo ndlela.
