Cov ntaub ntawv encoding Cov txheej txheem. Kev tshaj tawm. Encoding yog tus txheej txheem ntawm converting cov cov ntaub ntawv los yog muab ib ntus ntawm cov cim, cov cim, cov tsiaj ntawv thiab lwm yam, rau hauv ib hom ntawv teev tseg, rau kev ruaj ntseg kis tau tus mob ntawm cov ntaub ntawv . Decoding yog tus txheej txheem rov qab ntawm encoding uas yog rho tawm cov ntaub ntawv los ntawm lub converted hom ntawv.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub ntsiab lus ntawm encoder?
encoder . Noun. (plural encoders ) Ib qho cuab yeej siv los ua encode ib lub teeb liab rau cryptography lossis compression.
Tsis tas li ntawd, lub ntsiab lus ntawm encoder thiab decoder yog dab tsi? Ib encoder / decoder yog lub cuab yeej kho vajtse uas txhais cov ntaub ntawv thiab hloov nws mus rau hauv cov lej, thaum tseem muaj peev xwm hloov cov lej ntawd rov qab mus rau nws qhov qub. Hauv kev suav, ib encoder yuav siv sij hawm ib ntus ntawm cov cim lossis cov teeb liab analog thiab tsim nws rau kev sib kis tau zoo thiab / lossis khaws cia.
Yog li ntawd, kev siv cov ntaub ntawv encoding yog dab tsi?
Encoding koom nrog siv ntawm ib tug code hloov original cov ntaub ntawv rau hauv ib daim ntawv uas yuav siv tau los ntawm cov txheej txheem sab nraud. Hom code siv los hloov cov cim yog hu ua American Standard Code for Information Interchange (ASCII), feem ntau siv. encoding scheme rau cov ntaub ntawv uas muaj cov ntawv nyeem.
Dab tsi yog encoding thiab nws hom?
Encoding yog cov txheej txheem ntawm kev hloov cov ntaub ntawv los ntawm ib daim ntawv mus rau lwm qhov. Muaj ob peb hom ntawm encoding , suav nrog duab encoding , audio thiab video encoding , thiab tus cwj pwm encoding . Media ntaub ntawv yog feem ntau encoded txuag chaw disk.
