I-LM1881 Isihlukanisi Sokuvumelanisa Ividiyo SOP-8
Isihlukanisi sokuvumelanisa i-LM1881Video sikhipha ulwazi olushukumisayo oluhlanganisa ukuvumelanisa okuyinhlanganisela nokuma mpo, isikhathi sokuqhuma/emuva kovulandi, kanye nolwazi lwenkundla oluyinqaba/ngisho oluvela ku-NTSC,PAL*kanye namasiginali wevidiyo we-SECAM anobude obuvela ku-0.5Vto2Vp. ekwazi ukuhlinzeka ngokuhlukana kokuvumelanisa kumasignali wevidiyo angajwayelekile, anesilinganiso esivundlile esisheshayo. Okukhiphayo okuma mpo kukhiqizwa onqenqemeni olukhuphukayo lwe-serration yokuqala esikhathini sokuvumelanisa esiqondile. Okuphumayo okuzenzakalelayo okuqondile kukhiqizwa ngemva kokulibaziseka kwesikhathi uma umphetho okhuphukayo oshiwo ngenhla ungenzeki phakathi nesikhathi sokulibaziseka esisethwe ngaphandle, njengoba kungase kube njalo ngesignali yevidiyo engajwayelekile.
LM1881 Ividiyo Vumelanisa Umhlukanisi
Incazelo
l Ividiyo ye-LM1881 ukuvumelanisa isihlukanisi akhiphe ukulinganisa Imininingwane okubala okuhlanganayo futhi mpo vumelanisa, ukuqhuma/ngemuva umpheme isikhathi, futhi eyinqaba/ngisho field Imininingwane kusukela ejwayelekile kubi uya ukuvumelanisa NTSC,PAL*kanye I-secam ividiyo amasignali nge-amplitude kusukela 0.5Vto2Vp-p.The edidiyele isifunda is futhi enekhono of ukuhlinzeka ukuvumelanisa Ukuhlukana ngoba non-standard, ngokushesha ovundlile isilinganiso ividiyo izimpawu. The mpo Okukhiphayo is Okhiqizwayo on the ukuphakama Unqenqema of the kuqala i-serration in the mpo ukuvumelanisa isikhathi. A ezenzakalelayo mpo Okukhiphayo is kukhiqizwa ngemuva a isikhathi ukubambezeleka if the ukuphakama Unqenqema okushiwo ngenhla akusho kwenzeka Ngaphakathi the ngaphandle isethi ukubambezeleka isikhathi, njalo njengamandla be the icala ngoba a okungajwayelekile ividiyo isignali.

Yokuphila Isikhathi Eside Ise
Uhlelo Lokuphila Isikhathi Eside luhlose ukuhlinzeka amakhasimende ethu ngolwazi ngezikhathi ezithile mayelana nesikhathi esilindelwe lapho imikhiqizo yethu inga-odwa khona. I-NLP ibuyekezwa futhi ibuyekezwa njalo yiThimba lethu Labaphathi Abaphezulu. Buka uhlelo lwethu lokuphila isikhathi eside lapha.
