Incazelo ephezuluI-SDI optical transceiverivele ngesisekelo se-transceiver ebonakalayo yevidiyo yedijithali evamile, kusetshenziswa indlela yombhalo wekhodi ye-H.264, ngokuvamile kusetshenziswa isixhumi esibonakalayo se-SDI.

I-SD/HD/3G-SDI imikhiqizo ye-transceiver optical yaqala ukuthuthukiswa futhi yasetshenziswa amakhasimende embonini yomsakazo nethelevishini.Zisetshenziswe kuma-studio we-TV kanye nokusakazwa bukhoma kwe-Universiade, futhi kamuva zanwetshwa emkhakheni we-1080P wokuqapha okuchazwa okuphezulu, ngedatha yokulawula okuphambene;isilinganiso singu-1.485G (esaziwa nangokuthi i-1.5 G, ehambisana ne-SMPTE-292M ejwayelekile, esekela i-720P) kanye ne-2.97G (ebizwa nangokuthi i-3G, ehambisana ne-SMPTE-424M ejwayelekile, esekela FULL HD 1080P).Qinisekisa ukuthi asikho isikrini sokuchaphaza, isikrini esimnyama nezinye izinto ngesikhathi sokudlulisa isithombe sencazelo ephezulu.

I-high-definition SDI optical transceiver yamukela ividiyo yedijithali engacindezelwanga ephezulu enencazelo ephezulu kanye nobuchwepheshe bokudlulisa i-fiber optical fiber esheshayo.Ngemva kokuguqula i-1.485Gbps HD-SDI isignali yedijithali ibe isignali yokubona, ingadluliselwa ku-fiber optical amakhilomitha angu-1-20 bese ibuyiselwa kusignali kagesi.Ifanele ukubhekwa kwevidiyo ye-SDI nokuthwebula ividiyo yebanga elide.Lolu chungechunge lwama-transceivers optical lunokusebenza okuzinzile, ikhwalithi yesithombe ecacile, ukuzinza okuphezulu, kanye nenkomba yesimo se-LED, engakwazi ukubona ngokunembile isimo sokusebenza se-transceiver optical.

I-HD Concept
Ake sibheke ukuthi i-1080i ne-1080p imeleni – kokubili i-1080i ne-720p kungamazinga aqashelwa umhlaba wonke we-HDTV yedijithali.Uhlamvu u-i lumele ukuskena okuxhumene, kanti uhlamvu P lumele ukuskena okuqhubekayo.1080 kanye no-720 bamele isixazululo esingafinyelelwa ngendlela eqondile.I-1080P okwamanje iyifomethi yesignali evamile ye-HD yasekhaya.

I-TV enencazelo ephezulu yedijithali wonke umuntu avame ukubhekisela kuyo ibhekisela ekusetshenzisweni kobuchwepheshe bedijithali kuyo yonke inqubo yokusakaza nokwamukela uchungechunge lwezimpawu ze-TV ezifana nokushuthwa, ukuhlela, ukukhiqiza, ukusakaza, ukudlulisa, nokwamukela.Umabonakude weDigital high-definition izinga eliphezulu kakhulu likamabonakude wedijithali (i-DTV), elifushanisiwe njenge-HDTV.Ithelevishini enokulungiswa okuphezulu okungenani enemigqa yokuskena evundlile engu-720, imodi yesikrini esibanzi esingu-16:9, kanye nokudluliswa kwamashaneli amaningi.Kunezinhlobo ezintathu zamafomethi wokuskena we-HDTV, okuyi-1280*720p, 1920*1080i kanye ne-1920*1080p.izwe lami lamukela i-1920*1080i/50Hz.
