Ingcaciso ephezuluI-SDI i-transceiver ebonakalayoiguqulwe ngesiseko se-transceiver ebonakalayo yedijithali yevidiyo yedijithali, isebenzisa indlela ye-encoding ye-H.264, ngokuqhelekileyo isebenzisa i-SDI interface.

I-SD/HD/3G-SDI iimveliso ze-transceiver optical zaqala zaphuhliswa kwaye zisetyenziswa ngabathengi kwishishini lerediyo kunye nomabonwakude. Ziye zasetyenziswa kwii-studio zeTV kunye nokusasazwa okubukhoma kwe-Universiade, kwaye kamva zandiswa kwintsimi ye-1080P yokubeka iliso ephezulu, kunye nedatha yokulawula umva; izinga yi-1.485G (eyaziwa ngokuba yi-1.5 G, ehambelana ne-SMPTE-292M standard, exhasa i-720P) kunye ne-2.97G (ebizwa ngokuba yi-3G, ehambelana ne-SMPTE-424M standard, exhasa i-FULL HD 1080P). Qinisekisa ukuba akukho sikrini sokutshiza, isikrini esimnyama kunye nezinye izinto ezenzeka ngexesha lokuhanjiswa kwemifanekiso ephezulu.

Inkcazo ephezulu ye-SDI i-transceiver optical transceiver ithatha ividiyo ekumgangatho ophezulu wedijithali enganyanzelwanga kunye ne-high-speed digital optical fiber transmission. Emva kokuguqula i-1.485Gbps HD-SDI isignali yedijithali kwisignali ye-optical, inokudluliselwa kwi-fiber optical ye-1-20 yeekhilomitha kwaye ibuyiselwe kwisignali yombane. Ifanelekile ukujongwa kwevidiyo ye-SDI kunye nokuthathwa kwevidiyo kumgama omde. Olu chungechunge lwe-transceivers optical lunomsebenzi ozinzileyo, umgangatho wesithombe esicacileyo, uzinzo oluphezulu, kunye nesalathisi sesimo se-LED, esinokujonga nge-intuitively isimo sokusebenza se-transceiver optical.

HD Concept
Makhe sijonge ukuba i-1080i kunye ne-1080p imele ntoni - zombini i-1080i kunye ne-720p ziyimigangatho evunyiweyo yedijithali yedijithali ye-HDTV. Unobumba u-i umele ukuskena okudityanisiweyo, kwaye unobumba P umele ukuskena okuqhubekekayo. I-1080 kunye ne-720 imele isisombululo esinokufezekiswa kwicala elithe nkqo. I-1080P ngoku yeyona ifomathi yomgangatho ophezulu we-HD ekhaya.

I-TV yedijithali enengcaciso ephezulu esetyenziswa ngumntu wonke ehlala ebhekisa kusetyenziso lobuchwepheshe bedijithali kuyo yonke inkqubo yosasazo kunye nokufumana uthotho lwemiqondiso ye-TV efana nokudubula, ukuhlela, imveliso, ukusasaza, usasazo kunye nolwamkelo. Umabonakude weDigital high-definition yeyona migangatho iphambili kumabonakude wedijithali (DTV), efinyeziweyo njenge-HDTV. Ngumabonakude onesombululo esiphezulu ubuncinane onemigca yokuskena ethe tyaba engama-720, imo yesikrini esibanzi esingu-16:9, kunye nosasazo lwamajelo amaninzi. Kukho iintlobo ezintathu zeefomati zokuskena ze-HDTV, ezizezi 1280*720p, 1920*1080i kunye ne-1920*1080p. ilizwe lam lamkela 1920 * 1080i/50Hz.
