Kwihlabathi losasazo oluhlala lutshintsha, ukuhambisa umxholo osemgangathweni ophezulu kubabukeli kubalulekile. Ukuze kufezekiswe oku, abasasazi baxhomekeke kubuchwepheshe obuphambili njengeenkqubo ezisebenzayo kunye neeprosesa zangaphambili. Ezi zixhobo zinamandla zidlala indima ebalulekileyo ekuqinisekiseni ukuhanjiswa okungenamthungo kwemiqondiso yosasazo. Kule bhlog, siza kujonga nzulu amandla amangalisayo eeprosesa ze-headend, sihlola indlela eziphucula ngayo umgangatho wokuphuma kunye nokuphucula amava ababukeli ngokubanzi.
Funda ngeeprosesa ze-head-end:
Eyona nto iphambili kuyo nayiphi na imisebenzi yokusasaza kukho indawo engaphambili, apho imiqondiso yesandi nevidiyo engenayo idlula kuthotho lweenkqubo ezibalulekileyo ngaphambi kokuba ifikelele kwizikrini zabaphulaphuli. Kule mihla yedijithali, iiprosesa zentloko zingundoqo wale misebenzi, ziguqula imiqondiso eluhlaza ibe ngumxholo olungele ukusasazwa.
Phucula umgangatho wesiginali:
Iprosesa engaphambili ixhotyiswe ngetekhnoloji yanamhlanje yokuphucula nokuphucula isignali yokufaka. Ezi prosesa zine-algorithms eziphambili ze-codec ezinciphisa ingxolo, ziphucula ukuchaneka kombala kwaye ziphucule ukucaca komfanekiso ukuze ziphucule kakhulu umgangatho wosasazo. Ngokuhlalutya ngobuchule nangokucubungula idatha yevidiyo neyomsindo, iiprosesa ezingaphambili ziqinisekisa ukuba ababukeli bafumana umxholo ngendlela yawo engcono, ongenazo iimpazamo kunye nezinto zakudala.
Lungiselela ukusebenza kakuhle kwe-bitrate:
Olunye uphawu oluphambili lweeprosesa ze-headend kukukwazi kwazo ukucinezela imiqondiso ngaphandle kokunciphisa umgangatho. Ngokusebenzisa itekhnoloji yokucinezela esebenza kakuhle, ezi zixhobo zinokunciphisa ubungakanani befayile yevidiyo ngelixa zigcina ukuthembeka okubonakalayo. Le nkqubo ivumela abasasazi ukuba badlulise umxholo ocacileyo ngaphandle kokugqithisa imijelo yabo yonxibelelwano, ngaloo ndlela besebenzisa ngokufanelekileyo izixhobo ze-bandwidth ezikhoyo.
Ukutshintshwa kwekhowudi okuhlengahlengiswayo:
Iiprosesa yesiphelo sentlokoIbonelela ngezakhono zokuguqula ikhowudi ukuze kukhuthazwe ukuhambelana okuphezulu kwizixhobo ezininzi kunye nezikrini. Ngenxa yokwanda kwamaqonga edijithali ahlukeneyo, kubalulekile ukuqinisekisa ukuba umxholo ufikelela kubaphulaphuli bakho kwifomathi efanelekileyo. Ezi prosesa zilungisa ngokuguquguqukayo iiparameter zekhowudi ezifana nesisombululo kunye ne-bitrate ngokusekelwe kubuchule besixhobo, ziqinisekisa amava okubukela angcono kakhulu nakweyiphi na isikrini, ukusuka kwiifowuni eziphathwayo ukuya kwiiTV ezinkulu.
Ukuhambisa ngendlela ekrelekrele kunye nokudibanisa izinto ezininzi:
Ukuze badlulisele ngempumelelo iitshaneli ezininzi ngaxeshanye, iiprosesa ze-head-end zisebenzisa iindlela eziphambili zokuhambisa kunye nokudibanisa i-multiplexing. Ezi nkqubo zivumela abaqhubi ukuba banike i-bandwidth ngokufanelekileyo, baphathe ubungakanani obukhulu bezinto ezifakwayo kwaye baqinisekise utshintsho oluhamba kakuhle phakathi kwemithombo eyahlukeneyo yomxholo. Ngokulawula ukuhamba kwesignali ngobuchule, iiprosesa ze-head-end ziphucula kakhulu ukusebenza kakuhle kwenethiwekhi ngelixa zisusa ukuphazamiseka kwesignali.
Ikamva losasazo:
Njengoko imeko yosasazo iqhubeka nokutshintsha ngesantya esiphezulu, iiprosesa ezisebenzisa iintloko zidlala indima ebalulekileyo ekuvumela abasasazi ukuba bahlale bekwinqanaba eliphezulu lobuchwepheshe. Ezi zixhobo ziqinisekisa inkxaso yemigangatho emitsha efana ne-Ultra HD kunye neefomathi zesandi ezintywilisiweyo, zivumela abasasazi ukuba banike amava aqinisekileyo kwixesha elizayo kubaphulaphuli besebenzisa uphuhliso lwamva nje lobuchwepheshe.
Isishwankathelo:
Kwishishini losasazo lanamhlanje elinokhuphiswano olukhulu, ukuhambisa umxholo osemgangathweni ophezulu kubalulekile ekutsaleni ingqalelo yabaphulaphuli bakho.Iiprosesa zentlokozizixhobo zokufezekisa oku, ukuphucula ukusebenza kakuhle kwemveliso, ukuphucula umgangatho wesignali kunye nokuphucula amava okubukela ngokubanzi. Ngokusebenzisa amandla ezi zixhobo ziphambili, abasasazi banokuhlala phambili, behambisa umxholo obandakanya abaphulaphuli kwaye ubancede bakhe unxibelelwano oluhlala luhleli kwindawo yeendaba zedijithali ezihlala zitshintsha.
