Kukho izinto ezininzi ezichaphazela ikhwalithi yezwi: uxhulumaniso lwebhanki, i-bandwidth, i-hardware, isofthiwe kunye ne teknoloji ngokwayo. I-bandwidth, i-hardware kunye nezixhobo zesofthiwe zisekulawuleni kwethu - sinokutshintsha size siphucule kwaye siphucule kuzo; ngoko xa sithetha ngekhwalithi yezwi kwiVoIP, sisoloko sibeka umunwe kwi-teknoloji ephantsi, into engaphaya kokulawula kwethu njengabasebenzisi. Into evelele yeTheknik ye-VoIP yinkcenkceshelo yedatha.
Yintoni iCompression Compression?
Uxinzelelo lweenkcukacha yinkqubo apho idatha yelizwi ixininiswe ukuyenza ibe yinto encinci yokudlulisa. Iprogram yoxinzelelo (ebizwa ngokuba yi- codec ) idibanisa iisalathisi zezwi kwidatha yedijithali yokuba ixakeke kwiipakethe ezikhanyayo ezithunyelwa kwi-intanethi. Kuloo ndawo, la mapakethi adibaniswa kwaye anikwe ubungakanani bawo bokuqala (nangona kungekho njalo), kwaye aguqulelwe kwizwi le-analog kwakhona, ukuze umsebenzisi angava.
IiCodec ayisebenzisi nje kuphela ukunyanzelisa, kodwa kunye nokufakela ikhodi, okuthi, ngokutsho nje kukuguqulelwa kwezwi le-analog kwidijithali engadluliselwa kwiinkonzo ze-IP.
Umgangatho kunye nokusebenza kakuhle kwesofthiwe yoxinzelelo, ngoko, unempembelelo enkulu kwizwi leencoko zeVoIP. Kukho ubuchwephesha obugqithisileyo kwaye kukho izinto ezincinci. Ukubhetele kukuthi, iteknoloji nganye yoxinzelelo yenzelwe ukusetyenziswa ezithile phantsi kweemeko ezithile. Emva kokunyanzeliswa, ezinye iikhompyutheni zoxinzelelo zenza ilahleko ethile ngokwemigqaliselo yedatha kunye neepakethi. Oku kubangelwa kumgangatho ombi wezwi.
I-VOIP kunye neCompression Compression
I-VoIP idibanisa kwaye iphoxise idatha yedatha ngendlela enje yokuba ezinye zezinto zomlambo womculo zilahlekile. Oku kubizwa ngokuba yilahleko. Ukulahlekelwa akuyona into ekhuni kumgangatho wezwi kakhulu kunokuba kunenjongo. Ngokomzekelo, izandi ezingenakuvakala ngendlebe yomntu (ngokuphindaphindiweyo ngaphantsi okanye ngaphaya kwelo lithengiso levayo) lilahlwa kuba luya kuba lusizo. Kwakhona, ukulahla kulahliwe. Iinqununu zemizuzu yezwi elivakalayo lilahlekile ngokunjalo, kodwa iincinci ezincinci ezilahlekileyo ngelizwi azikuthinteli ekuqondeni oko kuchazwayo.
Ngoku, ukuba umniki-nkonzo wakho usebenzisa i-soft software software, uya kuvuya; enye inokuba ufanele ukukhalaza kancinci. Namhlanje, ubuchwepheshe bokuxilonga buye bukhulu kakhulu kangangokuba ukuphuma kwezwi kuphelela ngokugqibeleleyo. Kodwa ingxaki ixhomekeke ekukhethweni kwesofthiwe yoxinzelelo: isofthiwe ehlukileyo yoxinzelelo iyavumelana nezidingo ezahlukeneyo. Ngokomzekelo, kukho ezinye zezwi, ezinye zeedatha kunye nezinye zefeksi. Ukuba uzama ukuthumela ifeksi usebenzisa isofthiwe yoxinzelelo lwezwi, umgangatho uya kubandezeleka.
Ukuncintwa kwedatha, xa kuphuhliswe kakuhle kwaye kusetyenziswe kakuhle, ingaba yinto ebalulekileyo eyenza iVoIP ngenhla ifowuni yomhlaba ngokubhekiselele kumgangatho wezwi, kwaye yenza kube ngcono. Oku kunokwenzeka xa nje ezinye iimeko (umda we-bandwidth, i-hardware njl njl) zilungile. Ekubeni ukunyanzeliswa kukukhanyisa umthwalo wedatha ukuba udluliselwe kwisithuba esithile, iziphumo ezingcono zifikeleleke.
