Kwinkalo yosasazo lwedijithali, iiprosesa zentloko-siphelo zidlala indima ebalulekileyo ekuhanjisweni ngokufanelekileyo kwemiqondiso kamabonwakude neyerediyo.Eli nqaku lijolise ukucacisa ukuba yintoni i-headend yedijithali kunye nokubaluleka kweprosesa ye-headend kule nkqubo.
Yintoni isihloko sedijithali?:
Isihloko sedijithali sibhekisa kwindawo esembindini yothungelwano losasazo olufumana, luqhube kwaye lusasaze imiqondiso yesathelayithi, intambo okanye umabonakude osemhlabeni kunye nonomathotholo.Yintliziyo yenkqubo, ukuqokelela izibonakaliso kwimithombo emininzi kwaye iguqulelwe kwifomathi efanelekileyo yokusasazwa kwinethiwekhi.I-digital front-end iqinisekisa ukuba umxholo uhanjiswa kubaphulaphuli bokugqibela ngendlela ephezulu kunye nokuhambelana.
Indima ye-head-end processor :
Iiprosesa yesihloko yinxalenye ebalulekileyo ye-headend yedijithali kwaye inoxanduva lokulawula kunye nokucubungula iimpawu ezingenayo.Umsebenzi wayo ophambili kukucubungula kunye nokucacisa iindidi ezahlukeneyo zesandi kunye nevidiyo kwiifomathi ezifanelekileyo zokusasazwa kwiiplatifti ezininzi kunye nezixhobo.Isebenza njengesango phakathi komxholo wosasazo kunye nothungelwano losasazo.
Iprosesa ye-head-end ifumana imiqondiso evela kwimithombo eyahlukeneyo efana nokutya kwesathelayithi, amajelo asekuhlaleni kunye nemithombo ye-Intanethi.Le miqondiso iyadityaniswa, ihlaziywe kwaye iguqulelwe kwifomathi eqhelekileyo kusetyenziswa iindlela ezikhethekileyo zokukhowuda kunye neendlela zokudlulisa iikhowudi.Emva koko iprosesa yenza ii-multiplexes, eziyimiqulu yamajelo okanye iinkonzo ezinokusasazwa kunye kwifrikhwensi enye.
Iprosesa ye-head-end iphinda iphathe iinkqubo zokufikelela kwimiqathango ukuqinisekisa ukuhanjiswa komxholo okhuselekileyo.Ifihla kwaye ikhuphe imiqondiso ukuthintela ukufikelela okungagunyaziswanga kunye nobuqhetseba.Ukongeza, yenza iitshekhi ezahlukeneyo zomgangatho kunye nemisebenzi yokubeka iliso ukugcina ingqibelelo yomxholo wosasazo.
Izibonelelo kunye nenkqubela phambili :
Njengoko itekhnoloji ihambela phambili, iiprosesa zentloko ziyaqhubeka nokuvela ukuxhasa iimfuno zosasazo lwangoku.Ngoku babandakanya izinto ezinje ngekhowudi yevidiyo ephucukileyo, amandla okusasaza, iikhowudi zomsindo eziphucukileyo, kunye nokuhambelana nemigangatho eyahlukeneyo yothutho.Ezi zongezelelo zenza ukuba abaqhubi banike umxholo wenkcazo ephezulu, iinkonzo ezisebenzisanayo kunye nokusetyenziswa ngokufanelekileyo kwe-bandwidth.
Iprosesa yentloko-isiphelo isebenza njengeyunithi yokulawula ephakathi, inika ukuguquguquka kunye nokulinganisa kubaqhubi benethiwekhi.Ibavumela ukuba bongeze okanye basuse ngokulula amajelo, benze ngokwezifiso iipakethe zomxholo, kwaye baziqhelanise nokutshintsha ukhetho lwabaphulaphuli.Ngokuphinda-phinda ngezibalo, iprosesa yentloko-yesiphelo inika amandla izibonelelo ngokwemfuno yokwandisa ukusetyenziswa kwe-bandwidth, ngaloo ndlela igcina iindleko zabaqhubi.
Isiphelo :
Isishwankathelo,abaqhubekekisi bentlokozingumqolo weenkqubo ze-headend zedijithali kwaye zinoxanduva lokucubungula, ukulawula, kunye nokusabalalisa imiqondiso yeaudio kunye nevidiyo kwiiplatifti ezahlukeneyo.Idlala indima ebalulekileyo ekuqinisekiseni ukuba ababukeli bafumana amava okubukela angenamthungo, akumgangatho ophezulu.Njengoko ukuqhubela phambili kuqhubeleka, iiprosesa zentloko ziyaqhubeka nokuvela kunye nokuziqhelanisa nemeko yosasazo ehlala itshintsha.
