Iipakethi zesandi nevidiyo zidityanisiwe namaphawu okulinganisa ixesha ukuze ibhokisi esetiweyo ephezulu ingaqala ukudlala ukusuka naphi na kwi-stream, ngaphandle kwesikhokelo kunye nokungagcini phantsi ifayile yonke. Lo yilo luthetha ukuba MPG imixholo idlala kwizixhobo ezidala ngaphandle kwengxaki kwaye ingqubana nesoftware yakudala rhoqo.

Iifayile eziphumayo ezinkqubo zifomati inkqubo yakhiwa ukuba ikhuphe, hayi ukhetho umntu owenzayo ngoku. MPG yi DVD yoshicilelo lwesoftware yolubanzi, i-camcorders edala kunye nezixhobo zokusasaza ukutya ziyazi, ngoko ihlala isetyenziswa kwezi ntambo.

Ingaba i-MPG ifana nefomati yesinye isiqalelo?

Ewe. Eli xhulumaniso negama elide okanye elifutshane obona ngaphaya kwayo lichaza ifomati enye ephantsi, kwaye nantoni na efunda okanye ifunda zombini. Amagama amabini akwimbali: umda wegama lefayile leimpawu ezisibhozo ukusuka kwi DOS yexesha, umboneleli onika igama lodweliso lwenkqubo endaweni yefomati yefayile, okanye iinkqubo ezimbini eziqhelekileyo ezihlukileyo. Uguqulelo lwesibini luvelisa iziphumo ezifanayo, ngoko sebenzisa naluphi na uxhulumaniso isoftware kwinye icala ilindele.

Iinkqubo zekhompyutha

Ingaba ndimele ndigcine iifayile ezintsha njenge MPG?

Ukuba into ephantsi kwendlela ifuna oku. Ifomati iyaqhubeka ivula, kwaye akukho mcimbi wokuguqula uvimba ongazibangela iingxaki, kodwa ayikwazi ukuqhubeka apho isixhobo okanye usebenziso luya khona.

Okubalulekileyo kulapho ixesha licinga khona: iifayile ezincinci, abaqhubi abancinci, akukho msebenzi womnatha, kunye neempawu ezingafunekiyo. apho ezi zinto zicinga khona, ifomati ilungile. apho azisebenzi, le yisizathu sokuguqula.

Yintoni eyenza i-MPG yam ifile emva kokuguqula?

Icima ngokuzenzekelayo. Ulayisho phezulu kunye nesiphumo esiguqulwe kancinane zihlala kumaseva ethu malunga neyure ezi-24, ezishiya ixesha lokulayisha ezantsi impumelelo, kwaye zisuswa ngokuzenzekelayo. Uthutho luya kuhamba ngaphezulu kwe HTTPS kumgca omnye nolunye. Akukho mntu ufunda okuqulethekayo, akukho nto ibhalwe kwisikhokelo, akukho nto igqityiwe komnye umntu.
