I-mpikiswano apho isihloko siyilo mdlalo wokuqala wevidiyo ngumntu oye wendlula iminyaka engaphezu kwama-50. Uyakwazi ukubona ukuba into enjalo yokwenza ubuchwephesha iza kuba lula ukuyifaka, kodwa yonke ibilisa kwindawo yakho yegama elithi "umdlalo wevidiyo". Abalobi bembhalo bajonga ukuba uthetha umdlalo owenziwe ngekhomputha, usebenzisa imifanekiso eboniswe kwisixhobo sevidiyo njengesiTV okanye ukubeka iliso. Abanye bacinga umdlalo wevidiyo ukuba ibe yimuphi umdlalo wekhompyutha oboniswe usebenzisa ifowuni yokuphuma. Ukuba ubhalisela ukugqibela, ngoko uya kuqwalasela iCathode-Ray Raw Device Amusement ukuba ngumdlalo wokuqala wevidiyo.
Umdlalo:
Inkcazelo elandelayo isekelwe kuphando kunye namaxwebhu nge patent ebhalisiweyo yemidlalo (# 2455992). Akukho mzekelo osebenzayo womdlalo ukhona namhlanje.
Ngokusekelwe kwimiboniso ye-Radar yeMfazwe Yehlabathi, abadlali basebenzisa amaqhina ukuze bahlengahlengise umzila wemizila yokukhanya (iimfono) kwizame zokubethela iithagethi eziprintiweyo kwiinkcazo ezicacileyo zesikrini.
Imbali:
Ngama-1940, ngoxa i-intanethi yecandelo le-cathode ray efundwayo kwiimpawu zecomputer (ezisetyenziselwa ukuphuculwa kweethelevishini kunye nabagadi bamaphephandaba) uThys T. Goldsmith Jr. kunye no-Estle Ray Mann beza nombono wokudala umdlalo ephefumlelwe yiMfazwe yehlabathi ye-War II. Ngokudibanisa i-tube ye-cathode ray kwi-oscilloscope kunye nokwenza amaqhina alawula i-angle kunye ne-trajectory yendlela yokukhanya eboniswe kwi-oscilloscope, bakwazi ukuvula umdlalo we-missile apho, xa usebenzisa i-screen-overlays, yenze umphumo wokudubula iibhola kwiindawo ezahlukeneyo iithagethi.
Ngo-1947, i-Goldsmith kunye noMann bafake i-patent yesixhobo, bebiza ngokuba yiCathode-Ray Raw Device Amusement, kwaye banikezelwa ilungelo lobunikazi kunyaka olandelayo, okwenza kube ngumntu wokuqala we-patent yomdlalo we-elektroniki.
Ngelishwa, ngenxa yeendleko zezixhobo kunye neemeko ezahlukahlukeneyo, iCathode-Ray Tube Device Amusement ayizange ikhishwe kwindawo yokuthengisa. Iiprototypes ezenziwe ngezandla zange zenziwe.
Izixhobo:
- I-Tube ye-Cathode-Ray: Idala kwaye iguqule uphawu lwekhompyutha.
- I-Oscilloscope: Ubonisa uphawu lwekhompyutheni ngokusebenzisa imida yokukhanya kweso sihlo.
- Ukugqithwa kwesikrini: Iimifanekiso zemidlalo, ziprintiwe ngokugqithisa ngokucacileyo okufakela kwisikrini se-oscilloscope. Ukugqithiswa kwesikrini kwandiswe kamva kwikhonsoli yomdlalo wokuqala wevidiyo, iMagnavox Odyssey .
- Iimpawu zokulawula: Ulungisa i-angle kunye nokunyakaza kwemigodi yokukhanya kwi-Oscilloscope.
I-Tech:
I-Cathode-Ray Tube yisistim esingakwazi ukubhalisa nokulawula umgangatho wesigxina sekhompyutheni. Xa sele ixhunywe kwi-Oscilloscope, isalathisi sekhompyutheni iboniswa ngokubonakalayo kwi-monitor ye-Oscilloscope njengesibane sokukhanya. Umgangatho wesiganeko wekhompyutheni ulinganiswa ngendlela umbane wokukhanya ohamba ngayo kunye nemigangatho yokubonisa.
Ulawulo lwee-knobs luhlengahlengisa amandla oveliso lwe-electronic nge-Cathode-Ray Tube. Ngokulungelelanisa amandla okubonakalisa iimpawu zokukhanya ezivela kwi-Oscilloscope zibonakala zihamba kwaye zijika, zivumela umdlali ukuba alawule indlela yokukhanya ehamba ngayo.
Emva kwesikrini sokugqitywa ngeefayile ezijoliswe kuzo kuzo kufakwa kwisikrini sase-Oscilloscope, umdlali uzama ukulungelelanisa i-ray ukuze alahlekise ithagethi. Enye yeendlela ezimangalisayo ezenziwa nguGoldsmith kunye noMann kwakuyimpembelelo yokwenza ukubonakala kokuqhuma xa ijoliswe. Oku kwenziwa ngokulungiswa komnxibelelwano odibeneyo (utshintshi olayitshiweyo olawula ukuhamba kwamandla ngesekethe) ukuba anqobe umxhasi kwi-Cathode-ray Tube enephawu elinamandla kangangokuba lenza isibonakaliso siphume phambili kwaye sibonakale nje indawo ejikeleze indawo ejikelezayo, ngoko kudala ukubonakala kokuqhuma.
Umdlalo wokuqala wevidiyo ?:
Nangona iCathode-Ray Tube I-Adware Device iyenzeka ngowona mdlalo we-elektroniki wokuqala kwaye ikhonjiswe kwisebe, abaninzi abayifumani njengemidlalo yangempela yevidiyo. I sixhobo sizenzekelayo kwaye asisebenzisi nayiphina imifanekiso okanye iikhompyutheni ezifakwe kwiikhomputha, kwaye akukho khompyutha okanye idivaysi yememori isetyenziswe kuyo yonke ekudalweni okanye ekusebenzeni komdlalo.
Kwiminyaka emihlanu kamva, u-Alexander Sandy Douglas wenza i-intelligence engqondweni (AI) yomdlalo wekhompyutha obizwa ngo- Noughts kunye neeNqamlezo , kwaye emva kweminyaka emithandathu uWilly Higinbotham wenza i- Tennis yeBibini , yokuqala ibonisa umdlalo wekhompyutha. Zomibini zale midlalo zisebenzisa isibonakaliso se-oscilloscope kwaye zixutywe ukuba zithathe ityala njengemidlalo yokuqala yevidiyo, kodwa ayiyi kuba khona ngaphandle kokufumanisa kunye nobuchwepheshe obudalwe nguTomas T. Goldsmith Jr. kunye no-Estle Ray Mann.
Trivia:
- Ngaphandle kwelungelo lobunikazi kunye nezinye izicwangciso zeprojekthi, akukho mzekelo osebenzayo weCathode-Ray Tube I-Device Amusement Device.
- U-Inventor uThomas T. Goldsmith waqhubeka waba ngumboneleli womabonwakude, eqala njengeNqununu-Mongameli; UMlawuli woPhando lweDuMont, inethiwekhi yokuqala ye-TV yomnxeba wehlabathi.
