Zimbalwa izinto ezicasula kakhulu kunokubuka umdlalo weNdebe Yomhlaba, ugobe phambili ubambe i-remote njenge-talisman, bese uzwa umakhelwane wakho ememeza ethi "Goal!" lapho umdlalo usanda kuqala esikrinini sakho. Akukhona ukuthi baphila esikhathini esizayo noma banoxhumano oluxhaswe yi-NASA: bamane babukela umdlalo ngokubambezeleka okuncane kunawe. Nakuba ukusakazwa bukhoma kwangempela kungekho kwezemidlalo zanamuhla, kunezindlela zokusondela kakhulu esikhathini sangempela somdlalo. Futhi, njengoba kunjalo cishe njalo ngobuchwepheshe, ukulula kuza ngentengo: ukusakaza ngokuvamile kuhamba kancane kunethelevishini yasemhlabeni futhi kuhamba kancane kakhulu kunomsakazo.
Incazelo ilele ekubambezelekeni, okuyisikhathi esithathayo ukuthi isignali ihambe isuka enkundleni iye esikrinini sakho. Umsakazo uvame ukushesha ngoba uthumela umsindo kuphela futhi udinga ukucutshungulwa okuncane. Ithelevishini yedijithali yomhlaba (i-DTT) ingeza imizuzwana embalwa yokufaka ikhodi, ukusatshalaliswa, kanye nokucutshungulwa kwezithombe. Kodwa ukusakaza kunezela izendlalelo ezengeziwe ku-equation: amaseva, amanethiwekhi, ukucindezelwa, ukulungiswa kwekhwalithi, futhi, ngaphezu kwakho konke, i-buffer edumile. Le "cushion" yevidiyo elandwa uhlelo lokusebenza ngaphambi kokukukhombisa umdlalo yikona okuvimbela ukuphazamiseka, ukuthuthumela, kanye nokuguqulwa kwamaphikseli lapho uxhumano luhamba kancane, kodwa futhi yilokho okwenza ugubhe umgomo kamuva. Lapho uhlelo lokusebenza lugcwalisa ngokucophelela le buffer, umdlalo uzoba ozinzile, futhi uzoba kude nokusakaza bukhoma. Yingakho abantu ababili abasebenzisa uhlelo lokusebenza olufanayo bengathola ukusebenza okungalingani: idivayisi, inethiwekhi ye-Wi-Fi, ithelevishini, uhlelo lokusebenza, ngisho nangomzuzu oqale ngawo ukusakaza konke kudlala indima. Kunezindlela ze-low-latency, njenge-Low-Latency HLS noma i-LL-DASH, kodwa azitholakali njalo futhi ngokuvamile zidela ukuzinza ngenxa yesivinini.
Ngakho-ke, ungamvimba kanjani umakhelwane wakho ekubhubhiseni iNdebe Yomhlaba? Isixazululo esisebenza kahle kakhulu sisalokhu singesesimanje kakhulu: bukela umdlalo kuthelevishini yedijithali yasemhlabeni (i-DTT) uma utholakala. Uma kufanele uwusakaze, sebenzisa ikhebula le-Ethernet esikhundleni se-Wi-Fi, vala okunye ukulanda ekhaya, joyina ukusakaza kusenesikhathi, futhi ugweme ukumisa noma ukuhlehlisa, ngoba ngezinye izikhathi uhlelo lokusebenza alubuyeli endaweni eseduze kakhulu nokusakazwa bukhoma. Kufanelekile futhi ukuqhathanisa amadivayisi: amanye ama-TV anezinhlelo zokusebenza ezihamba kancane kunefoni ephathekayo, ibhokisi le-set-top, noma i-Chromecast. Iseluleko sami ukuthi wenze isivivinyo esisheshayo ngaphambi komdlalo omkhulu, hhayi ngomzuzu wama-89. Ngoba cha, ngeke uthole i-zero latency ngaphandle kokuthi usenkundleni yezemidlalo, kodwa unganciphisa ukubambezeleka ngokwanele ukuze ube ngowokuqala ukugubha umgomo. Noma, okungenani, ngesikhathi esifanayo nomakhelwane wakho.
