Ukuthuthukisa Ikhwalithi Yokusakaza Ngama-Head-End Processors: Ukukhulisa Ukusebenza Kakuhle Kokukhiphayo

Ezweni lokusakaza elihlala lishintsha, kubalulekile ukuletha okuqukethwe kwekhwalithi ephezulu kubabukeli. Ukuze kuzuzwe lokhu, abasakazi bathembele kubuchwepheshe obuthuthukile njengamasistimu asebenzayo namaphrosesa angaphambili. Lawa madivayisi anamandla adlala indima ebalulekile ekuqinisekiseni ukudluliswa kwezimpawu zokusakaza okungenamthungo. Kule bhulogi, sizongena sijule emakhonweni amangalisayo ama-headend processors, sihlola ukuthi athuthukisa kanjani ikhwalithi yokuphumayo futhi athuthukise ukuzizwisa kwababukeli.

Funda mayelana nama-head-end processors:

Enhliziyweni yanoma yimuphi umsebenzi wokusakaza ingaphambili, lapho amasiginali omsindo nevidiyo angenayo edlula ochungechungeni lwezinqubo ezibalulekile ngaphambi kokufinyelela izikrini zezethameli. Kule nkathi yedijithali, ama-head-end processors ayinsika yale misebenzi, aguqula amasiginali aluhlaza abe okuqukethwe okulungele ukusakazwa.

Thuthukisa ikhwalithi yesiginali:

Iphrosesa engaphambili ifakwe ubuchwepheshe obusezingeni eliphezulu ukuze ithuthukise futhi ithuthukise isignali yokufaka. Lawa maphrosesa afaka ama-algorithms e-codec athuthukile anciphisa umsindo, athuthukisa ukunemba kombala futhi athuthukise ukucaca kwesithombe ukuze athuthukise kakhulu ikhwalithi yokusakaza. Ngokuhlaziya ngobuhlakani nangokucubungula idatha yevidiyo neyomsindo, abacubunguli bamakhanda baqinisekisa ukuthi ababukeli bathola okuqukethwe ngendlela yakhona engcono kakhulu, ngaphandle kokuhlanekezelwa kanye nama-artifact.

Lungiselela ukusebenza kahle kwe-bitrate:

Esinye isici esibalulekile se-headend processors yikhono labo lokucindezela amasignali ngaphandle kokudela ikhwalithi. Ngokusebenzisa ubuchwepheshe bokucindezela obusebenzayo, lawa madivayisi angehlisa usayizi wefayela levidiyo ngenkathi egcina ukwethembeka okubonakalayo. Le nqubo yenza abasakazi bakwazi ukudlulisa okuqukethwe okunencazelo ephezulu ngaphandle kokucindezela iziteshi zabo zokuxhumana, ngaleyo ndlela basebenzise izinsiza ezitholakalayo zomkhawulokudonsa.

I-Adaptive Transcoding:

Iiprosesa yekhandaihlinzeka ngamakhono okudlulisela ikhodi aguquguqukayo ukuze kuthuthukiswe ukusebenzisana okuphelele kuwo wonke amadivayisi nezikrini eziningi. Ngokusabalala kwamapulatifomu edijithali ahlukahlukene, kubalulekile ukuqinisekisa ukuthi okuqukethwe kufinyelela izethameli zakho ngefomethi efanele. Lawa maphrosesa ashintsha ngokuguqukayo amapharamitha ombhalo wekhodi afana nokulungiswa kanye ne-bitrate ngokusekelwe kumakhono edivayisi, okuqinisekisa umuzwa ongcono kakhulu wokubuka kunoma yisiphi isikrini, kusukela kuma-smartphones kuya kuma-TV amakhulu.

Umzila ohlakaniphile kanye nokuphindaphinda:

Ukuze udlulise ngempumelelo iziteshi eziningi ngesikhathi esisodwa, ama-head-end processors asebenzisa umzila othuthukisiwe kanye nezindlela zokuphindaphinda. Lezi zinqubo zenza opharetha bakwazi ukwaba umkhawulokudonsa ngokuphumelelayo, baphathe amanani amakhulu okokufaka futhi baqinisekise ukushintshwa okushelelayo phakathi kokusakaza okuhlukahlukene kokuqukethwe. Ngokuphatha ngobuhlakani ukugeleza kwesignali, ama-head-end processors athuthukisa kakhulu ukusebenza kahle kwenethiwekhi kuyilapho esusa ukuphazamiseka kwesignali.

Ikusasa lokusakaza:

Njengoba indawo yokusakaza iqhubeka nokuthuthuka ngesivinini esisheshayo, amaphrosesa abamba iqhaza elikhulu ekuvumeleni abasakazi ukuthi bahlale besezingeni eliphezulu lobuchwepheshe. Amadivayisi aqinisekisa ukusekelwa kwamazinga asafufusa njenge-Ultra HD namafomethi omsindo agxilile, okuvumela abasakazi ukuthi balethe okuhlangenwe nakho kobufakazi besikhathi esizayo kubabukeli abasebenzisa intuthuko yakamuva yezobuchwepheshe.

Ngokufigqiwe:

Embonini yanamuhla yokusakaza enokuncintisana kakhulu, ukuletha okuqukethwe kwekhwalithi ephezulu kubalulekile ukuze udonse ukunaka kwababukeli bakho.Amaprosesa asezingeni eliphezuluangamathuluzi okufeza lokhu, ukuthuthukisa ukusebenza kahle kokuphumayo, ukuthuthukisa ikhwalithi yesiginali kanye nokuthuthukisa umuzwa wokubuka usuwonke. Ngokusebenzisa amandla alawa madivaysi athuthukile, abasakazi bangakwazi ukuhlala ngaphambi kwejika, balethe okuqukethwe okubandakanya izethameli futhi kuzisize zakhe ukuxhumana okuhlala njalo endaweni yemidiya yedijithali ehlala ishintsha.
