I-RAC (Radio Corporation of America, RCA) TheIsixhumi se-RCAyasungulwa.I-RCA yaziwa kakhulu ngokuthi i-lotus socket, eyaziwa nangokuthi i-RAC terminal, eyaziwa nangokuthi i-RAC interface, cishe yonke imikhiqizo ye-TV, isidlali seDVD inalesi sikhombimsebenzisi.Ayakhelwe ngokuqondile noma iyiphi i-interface eyodwa.Ingasetshenziselwa kokubili amasiginali wevidiyo alalelwayo najwayelekile.Futhi iyisokhethi yengxenye ye-DVD (YCrCb), kodwa inombolo zintathu.I-RCA ivamise ukuba yipheya yezimbobo zomsindo ezimhlophe nezimbobo zevidiyo eziphuzi.Ivamise ukuxhunywa kusetshenziswa i-RCA (evame ukwaziwa njengekhanda le-lotus), edinga kuphela ukuxhuma ikhebula le-RAC elijwayelekile elinekhanda le-lotus embobeni ehambisanayo.
Ukudluliswa kwesignali
Itheminali ye-RCA yamukela imodi yokudlulisa isignali ye-coaxial, i-axis emaphakathi isetshenziselwa ukudlulisa isignali, futhi ungqimba lokuxhumana lwangaphandle lusetshenziselwa ukubeka phansi.Ingasetshenziswa ezikhathini ezihlanganisa ividiyo ye-analog, umsindo we-analog, umsindo wedijithali kanye nokudluliswa kwengxenye ye-chromatic.Amatheminali omsindo we-RCA ngokuvamile anemibala ngamabhangqa: abomvu esiteshini esingakwesokudla futhi amnyama noma amhlophe esiteshini esingakwesokunxele.Kwezinye izimo, uxhumo lwekhebula eliphakathi nendawo nelizungezile linekhodi yombala ukuze kube lula ukuhlanganisa izintambo, kodwa zonke izixhumi ze-RCA kulo lonke uhlelo zinokusebenza okufanayo kukagesi.Ngokuvamile, imigqa ye-RCA ye-stereo yomsindo esele nengakwesokudla yeqembu, ukubukeka kwesiteshi ngakunye kuwumugqa.
Isitayela esibonakalayo
Ngokuvamile kubhanqiwe izimbobo zomsindo wesiteshi esingakwesokudla (obomvu) isiteshi esingakwesokunxele (esimhlophe) kanye nembobo yevidiyo (ephuzi)
Izinzuzo zesitayela se-plug
I-interface ye-RAC inika amandla ukuhlukaniswa kokudluliswa komsindo nevidiyo, okugwema ukuwohloka kwekhwalithi yesithombe ngenxa yokuphazamiseka komsindo/ividiyo eyingxubevange.Isixhumi esibonakalayo esisetshenziswa kakhulu kumadivayisi alalelwayo namavidiyo, cishe yonke idivayisi yomsindo nevidiyo inikeza lesi sikhombimsebenzisi somsindo nevidiyo okokufaka nokuphumayo.
Ukubi
Ngenxa yokudluliswa kwesixhumi esibonakalayo se-RAC kuseyisignali yevidiyo eyinhlanganisela yokukhanya/i-chrominance (Y/C), kusadingeka ukubonisa okokusebenza kokuhlukanisa ukukhanya/umbala kanye nokuqoshwa kwe-chroma emfanekisweni, le nqubo yokuhlanganisa yokuqala futhi yokuhlukanisa izobangela nakanjani ukulahleka kwesignali yombala. , i-chroma nesignali yokukhanya nakho kunethuba elikhulu lokuphazamisana ukuze kuthinte ikhwalithi yesithombe sokugcina esiphumayo.I-RAC isenempilo ethile, kodwa ayikwazi ukusetshenziswa ezimeni lapho imikhawulo ebonakalayo ifunwa khona ngenxa yengxube yayo ye-Y/C engenakunqobeka.
