Hauv kev tshaj tawm digital, lub taub hau-kawg processors ua lub luag haujlwm tseem ceeb hauv kev sib kis tau zoo ntawm cov xov tooj cua thiab xov tooj cua.Tsab ntawv xov xwm no yog txhawm rau qhia meej tias lub taub hau digital yog dab tsi thiab qhov tseem ceeb ntawm headend processor hauv qhov system no.
Dab tsi yog digital headend?:
Lub taub hau digital yog hais txog lub hauv paus hub ntawm kev tshaj tawm xov xwm uas tau txais, txheej txheem thiab xa tawm satellite, cable lossis terrestrial TV thiab xov tooj cua teeb liab.Nws yog lub plawv ntawm lub kaw lus, sau cov teeb liab los ntawm ntau qhov chaw thiab hloov lawv mus rau hauv ib hom tsim nyog rau kev faib tawm hauv lub network.Cov digital pem hauv ntej-kawg ua kom cov ntsiab lus xa mus rau cov neeg tuaj saib kawg hauv qhov zoo thiab zoo ib yam.
Lub luag haujlwm ntawm lub taub hau-kawg processor:
Covheadend processor yog ib feem tseem ceeb ntawm digital headend thiab yog lub luag haujlwm rau kev tswj thiab ua cov khoom xa tuaj.Nws lub luag haujlwm tseem ceeb yog ua cov txheej txheem thiab txiav txim siab ntau hom suab thiab video teeb liab rau hauv cov qauv tsim nyog rau kev faib tawm thoob plaws ntau lub platform thiab cov khoom siv.Nws ua raws li lub rooj vag ntawm tus tshaj tawm xov xwm cov ntsiab lus thiab kev faib tawm network.
Lub taub hau-kawg processor tau txais cov teeb liab los ntawm ntau qhov chaw xws li satellite feeds, cov channel hauv zos thiab hauv Internet.Cov teeb liab no tau sib xyaw ua ke, txiav txim siab thiab hloov mus rau hauv hom qauv siv tshwj xeeb encoding thiab transcoding cov tswv yim.Tus processor ces generates multiplexes, uas yog bundles ntawm raws los yog kev pab cuam uas yuav kis tau ua ke nyob rau hauv ib tug ntau zaus.
Lub taub hau-kawg processor kuj tseem tswj xyuas cov txheej txheem nkag mus kom ntseeg tau ruaj ntseg cov ntsiab lus faib.Nws encrypts thiab decrypts cov teeb liab los tiv thaiv kev nkag mus tsis raug cai thiab piracy.Tsis tas li ntawd, nws ua ntau yam kev kuaj xyuas zoo thiab saib xyuas cov haujlwm kom muaj kev ncaj ncees ntawm cov ntsiab lus tshaj tawm.
Cov txiaj ntsig thiab kev nce qib:
Raws li kev siv thev naus laus zis, headend processors txuas ntxiv txhim kho los txhawb cov kev xav tau ntawm kev tshaj tawm niaj hnub no.Lawv tam sim no suav nrog cov yam ntxwv xws li kev tshaj tawm video siab, muaj peev xwm streaming, cov suab codecs siab heev, thiab kev sib raug zoo nrog cov qauv thauj sib txawv.Cov kev txhim kho no ua rau cov neeg ua haujlwm xa cov ntsiab lus siab, kev pabcuam sib tham thiab siv tau zoo bandwidth.
Lub taub hau-kawg processor ua raws li lub hauv paus tswj kev tswj hwm, muab kev yooj yim thiab scalability rau cov tswv lag luam.Nws tso cai rau lawv yooj yim ntxiv lossis tshem tawm cov channel, hloov kho cov ntsiab lus pob, thiab hloov pauv hloov cov neeg nyiam.Los ntawm kev txheeb cais kev sib tw, lub taub hau-kawg processor dynamically faib cov peev txheej raws li qhov xav tau los txhim kho kev siv bandwidth, yog li txuag cov nqi rau cov tswv lag luam.
Xaus:
Hauv cov ntsiab lus,lub taub hau processorsyog cov caj qaum ntawm cov tshuab digital headend thiab muaj lub luag haujlwm rau kev ua, tswj, thiab faib cov suab thiab video teeb liab hla ntau lub platform.Nws ua lub luag haujlwm tseem ceeb hauv kev ua kom cov neeg saib tau txais kev pom zoo, tsis muaj txiaj ntsig zoo.Raws li kev nce qib mus ntxiv, headend processors txuas ntxiv hloov zuj zus thiab hloov mus rau qhov hloov pauv hloov pauv ib puag ncig.
