Ingxabano okuthiwa yiyiphi umdlalo wokuqala wevidiyo yilawo oye waqhubeka iminyaka engaphezu kwengu-50. Uzobheka ukuthi into efana nezobuchwephesha izokuba lula ukufaka amaphuzu, kepha konke kubizela ekuchazeni kwakho igama elithi "umdlalo wevidiyo". Abalobi babheka ukuthi kusho umdlalo okhiqizwa ngekhompiyutha, besebenzisa ihluzo eziboniswe kudivayisi yevidiyo njenge-TV noma ukuqapha. Abanye babheka umdlalo wevidiyo ukuthi ube yimuphi umdlalo we-elekthronikhi oboniswe usebenzisa idivayisi yokukhipha ividiyo. Uma ubhalisa kulokhu okulandelayo, khona-ke uzocabangela idivayisi ye-Cathode-ray ye-Amusement Device ukuze ibe umdlalo wevidiyo wokuqala.
Umdlalo:
Incazelo elandelayo isekelwe ocwaningweni namadokhumenti nge-patent ebhalisiwe yemidlalo (# 2455992). Ayikho imodeli yokusebenza yomdlalo ikhona namhlanje.
Ngokusekelwe kwi-World War II ekhombisa ama-radar, abadlali basebenzisa ama-knob ukuze balungise ukulandelana kwezigxobo ezikhanyayo (imicibisholo) ngomzamo wokushaya amathekisthi abhalwe ephepheni elikhanyayo.
Umlando:
Ngomnyaka we-1940, ngenkathi kugcizelelwe ukuthuthukiswa kwe-tube tube ukufundwa kwezimpawu zamagetsi (okusetshenziselwa ekuthuthukiseni amathelevishini kanye nabaqapheli) izazi zefilosofi uThomas T. Goldsmith Jr. kanye no-Estle Ray Mann bafika nomqondo wokudala umdlalo we-elektroniki olula ephefumulelwe yi-World War II display radar. Ngokuxhuma i-tube ye-cathode ray kwi-oscilloscope kanye nama-knobs aqondisa i-angle kanye ne-trajectory yezinto ezikhanyayo eziboniswe kwi-oscilloscope, bakwazi ukusetha umdlalo we-missile ukuthi, uma usebenzisa ukubhoboza kwesikrini, wadala umphumela wokudubula imicibisholo ehlukahlukene izinhloso.
Ngo-1947, i-Goldsmith no-Mann balethe i-patent yedivayisi, beyibiza ngokuthi idivaysi yokukhangisa ye-Cathode-Ray Tube, futhi banikezwa ilungelo lobunikazi ngonyaka olandelayo, okwenza kube yilokuqala i-patent yomdlalo we-elektroniki.
Ngeshwa, ngenxa yezindleko zokusebenza kanye nezimo ezihlukahlukene, idivayisi ye-Cathode-Ray ye-Amusement Device ayizange ikhishwe emakethe. Ama-prototypes ezenziwe ngezandla kuphela adalwe.
Izingxenye:
- I-Cathode-Ray Tube: Yakha futhi iguqula isignali ye-elektroniki.
- I-Oscilloscope: Ibonisa isignali ye-elektronike ngemisebe yokukhanyisa kumqapha.
- Ukuguqulwa Kwesikrini: Ihluzo zegeyimu, ephrintiwe ngokugqama okucacile okunamathiselwe kusikrini se-oscilloscope. Ukukhishwa kwesikrini kamuva kusetshenziselwa ikhonsoli yegeyimu yekhaya yokuqala, i- Magnavox Odyssey .
- Amacu omlawuli: Ulungisa ukuhamba nokuhamba kwemishayo yokukhanya ku-Oscilloscope.
I-Tech:
I-Tube ye-Cathode-Ray iyisidingo esingakwazi ukubhalisa nokulawula ikhwalithi yesignali kagesi. Uma ixhunywe ku-Oscilloscope, isignali ye-elekthronikhi iboniswa ngokubonakalayo ekuqapha kwe-Oscilloscope njengesibani sokukhanya. Ikhwalithi yesignali ye-elekthronikhi ilinganiswa ngendlela i-light of light ehamba ngayo futhi ijika nge-curve.
I-knobs yokulawula ilungisa amandla we-electronic signal okukhishwa yi-Cathode-Ray Tube. Ngokulungisa amandla esignali, izibani zokukhanyisa ezivela ku-Oscilloscope zibonakala zihamba futhi zijika, okuvumela umdlali ukuba alawule i-trajectory lapho i-ray yokukhanya ihamba khona.
Uma isikrini sicindezelekile ngefrifikhi ehlosiwe ephrintiwe kuzo kufakwa esikrinini se-Oscilloscope, umdlali uzama ukulungisa i-ray ukuze aphikisele kulesi sitshelwa. Enye yezimanga ezimangalisayo uGoldsmith noMann abakhuphuka nazo kwaba nomphumela wokwenza ukubonakala kokuqhuma lapho ihlaselwa. Lokhu kwenziwa ngokulungisa umxhumanisi ohambayo (inkinobho elayishwayo elawula ukugeleza kwamandla ngokusebenzisa isifunda) ukuze inqobe ukumelana neThubhu ye-Cathode-ray ene signal elinamandla kangangokuba yenza isibonakaliso singapheli futhi sibonakale njengendlela indawo evulekile, ngakho-ke kudala ukubonakala kwe-explosion.
Igeyimu Yokuqala Yevidiyo ?:
Nakuba idivaysi yokukhangisa ye-Cathode-ray ye-Ray iyinhlangano ye-elektroniki ye-patented yokuqala futhi iboniswa kumqapha, abaningi abakubheki njengemidlalo yangempela yevidiyo. Idivaysi i-mechanical kuphela futhi ayisebenzisi noma iyiphi i-graphics noma i-computer eyakhelwe ihluzo, futhi akukho idivayisi yekhompiyutha noma yememori esetshenziselwa konke ekudalweni noma ekusebenzeni komdlalo.
Eminyakeni emihlanu kamuva, u-Alexander Sandy Douglas wakhe i-intelligence yokufakelwa (AI) yomdlalo wekhompiyutha okuthiwa u- Noughts and Crosses , futhi ngemva kweminyaka eyisithupha uWilly Higinbotham wakhetha iTennis for Two , umdlalo wokuqala wekhompyutha owawuboniswa umphakathi. Yombili yale midlalo isebenzisa ukuboniswa kwe-oscilloscope futhi ixubene ukuthatha isikweletu njengemidlalo yokuqala yevidiyo, kodwa futhi ngeke ibe khona ngaphandle kokutholakala nokubuchwepheshe obudalwe nguThomas T. Goldsmith Jr. no-Estle Ray Mann.
I-Trivia:
- Ngaphandle kwe-patent namanye ama-schematic schematics, akukho modeli eyaziwayo yokusebenza yedivayisi ye-Cathode-Ray yokukhangisa yeThubhu ekhona.
- U-Inventor uThomas T. Goldsmith waba omunye wamaphayona wethelevishini, eqala njengoMengameli wePhini; Umqondisi Wezokucwaninga weDuMont, inethiwekhi yezwe yethelevishini yokuqala yokuthengisa.
