Lub ntsiab yuav tsum tau mus rau lub ntaus ntawv ntawm no hom - kom ntseeg tau ruaj khov thiab high-zoo tshaj tawm hauv xov TV cov kev pab cuam. Nyob rau hauv tas li ntawd, rau niaj hnub neeg siv yuav tsum txhawb receiver ntawm ib tug xov tooj tshaj multimedia nta xws li cov muaj peev xwm mus saib tau hauv internet pab. Yuav ua li cas yog lub ntsiab rau kev xaiv ntawm tuners uas muaj los ntawm Lavxias teb sab kws txawj? Yuav ua li cas cov qauv ntawm cov satellite receivers yuav tsum tau ntaus nqi mus rau feem ntau nrov nyob rau hauv Russia?

Xaiv ib tug satellite tuner: lub ntsiab tsis

Yam dab tsi tseem ceeb tshaj plaws thaum xaiv ib tug ntaus ntawv xws li ib tug tuner rau ib tug satellite tais? Ua ntej ntawm tag nrho cov, nws yog lub teeb liab kis tau tus mob interface. Feem ntau cov niaj hnub satellite receivers cov. Tab sis muaj analog pab kiag li lawm, raws li tau zoo raws li cov neeg uas khiav lag luam siv ib tug ua ke interface hom D2-MAC.

Muaj ntau cov neeg siv thiab cov kws txawj ntseeg tau hais tias, ntawm cov qauv uas yuav tsum muaj ib tug niaj hnub cov tuner, - T2. Kua zaub i.e. yuav tsum tau tshaj nrog tus thib ob tiam heev npaum compression algorithm multimedia kwj.

Ib tug heev ib qho tseem ceeb los ntawm lub standpoint ntawm zoo dluab nyob rau hauv ib tug satellite tuner yog ib feem xws li ib tug nti kho satellite coordinates, thiab cov module txiav xaiv txoj hauj lwm ntawm lub kav hlau txais xov. Yog hais tias lub tuner rau satellite TV yuav tsum nruab nrog qhov kev tsim nyog kho vajtse tivthaiv, lub TV tus tswv yuav tau mus saib ntau cov kev pab cuam.

Lwm tseem ceeb cov yam ntxwv ntawm tus ntaus ntawv nyob rau hauv lo lus nug, - tus nqi ntawm cov intermediate zaus band tshwmsim los ntawm lub receiver chipset converter uas converts tus frequencies hais txog lub siab, tsis tshua muaj. Qhov ntau dua tus nqi ntawm cov parameter nyob rau hauv lo lus nug, qhov ntau cov kev pab cuam koj yuav saib tau, Cycling TV-tuner rau satellite antennas. Thaum sufficiently xam tau tias yog respectable daim duab ntawm 900 thiab 2150. Satellite tuners uas txhawb cov coj bands yog tshaj nrog ib tug loj tus naj npawb ntawm cov qauv ntawm cov converters.

Kev Cai rau xaiv cov tuner: tsos thiab connectors kev pab txhawb nqa

Muaj ib tug ntau ntawm kev nyob rau hauv raws li uas koj muaj peev xwm tuaj tos no ntaus ntawv raws li ib tug satellite tuner. Cov cov tsos ntawm tus dais, raws li zoo raws li tus naj npawb thiab ntau yam ntawm kev txhawb connectors. Ib tug tseem ceeb tshaj yuav xaiv ntaus ntawv xws li ib tug TV-tuner rau satellite tais diav - tsos, raws li zoo raws li tswj devaysom yooj yim. Nws yog ib co ntshaw tias cov receiver yog tam sim no tus kheej tso rau uas mus tso saib ib tug ntau yam ntawm cov ntaub ntawv hais txog qhov tam sim no cov teeb meem yuav tsum tau solved kiag li lawm. Rau ntau cov neeg siv, ib tug tseem ceeb tshaj thaum xaiv tuner - lub hav zoov raws kev tswj nyees khawm, ntim tswj, raws li zoo raws li nkag tau mus rau cov zaub mov, thiab ncaj qha mus rau pem hauv ntej vaj huam sib luag. Lawv muaj peev xwm yuav pab tau, yog hais tias nyob ib co taw tes tej thaj chaw deb yuav tsis muaj.

Raws li ib tug txoj cai, niaj hnub cov qauv ntawm cov receivers nyob rau ntawm lub hauv pem hauv ntej sab ntawm lub connector rau nruab card nkag them raws, seev suab ntau interfaces, USB-ports yog siv los txuas flash drives thiab lwm hard drives, nyob rau hauv uas koj tau sau TV broadcasts. Nyob rau nram qab lub vaj huam sib luag ntawm cov receiver yog heev txaus interfaces xws li:

• RS232, siv mus txuas rau ib PC devaysa (feem ntau yog tshuab txais thaum koj hloov lub firmware ntawm lub receiver).
• S / PDIF, uas yog siv rau txuas lub tuner mus rau ntau yam suab pab kiag li lawm, raws li tau zoo raws li lub tsev ua yeeb yam tshuab.
• HDMI - lub interface mus rau kis dluab nyob rau hauv siab txhais.

Yog li, satellite tuner, uas muaj tus yam ntxwv uas muaj npe saum toj no, nyob rau hauv cov nqe lus ntawm tsos thiab cov connector nyiaj them yug yuav muab suav hais tias heev tseem ceeb rau niaj hnub tiam sis nyob rau hauv lub handheld ntaus ntawv ua lag luam nyob rau hauv nqe lus nug.

Xaiv ib tug satellite tuner: tej

Cov tom ntej no pab pawg neeg ntawm cov txheej xwm xaiv ntaus ntawv ntawm no hom muaj feem xyuam rau nws functionality. Uas lawv yuav tsum tau txais tshwj xeeb xim?

Ua ntej ntawm tag nrho cov, nws yog txaus siab los ntawm tus txheej txheem TV daim duab kis tau tus mob. Muaj yog ib tug "classic" hom ntawv, uas muaj ntau yam kws txawj xav txog outdated, tab sis nws yog ib yam, - MPEG2, thiab muaj ntau ntau cov technologically advanced - MPEG4. Lub ntsiab sib txawv nruab nrab ntawm lawv - lub rooj ntawm qhov kis tau cov duab. Yog li ntawd, cov kev pab txhawb txheem MPEG4 HD-tuner duab satellite kis tsis muaj teeb meem, tab sis ib tug uas yog tsuas tau tshaj MPEG2 hom ntawv, yuav tsis yog muab cov kev kawm bitrate.

Cov tom ntej no tseem ceeb tshaj plaws yam ntxwv devaysa nyob rau hauv lo lus nug, - ib tug Ethernet chaw nres nkoj uas los ntawm lub ntaus ntawv yuav ua kev cob cog rua rau hauv Internet, PC los yog LAN. Tsaug rau no feature receivers yuav deployed raws li ib tug kev muag zaub ib leeg caij nyob rau hauv lub network infrastructure, piv txwv li mus muab koom kev nkag mus rau kev txhais.

Muaj ntau ntawm niaj hnub no cov neeg uas nrhiav tau hais tias lawv satellite receiver yuav tsum pab txhawb cov CI txheem, uas koj mus cuag cov seev suab modules. Tsim Nyog kho vajtse Cheebtsam yog yus muaj los ntawm versatility: lawv yuav tsum tau ua hauj lwm rau lub teeb liab txais tos ob nyob rau hauv lub qhib thiab kaw broadcasts.

Lwm zoo kawg li feature satellite receiver - ib tug ua-nyob rau hauv hard drive. Cov uas tsim nyog nruab nrab tej zaum yuav ua hauj lwm, tshwj xeeb tshaj yog rau cov ntaubntawv povthawj siv TV cov kev pab cuam.

Tab sis nws yog pom zoo kom siv tag nrho cov sab nraud nyuaj tsav thiab tsis ua nyob rau hauv ntau cov qauv ntawm cov receivers. Cov satellite receiver nyob rau hauv cov ntaub ntawv no yog txawm peem rau nrog ib tug high-ceev chaw nres nkoj mus cuag tus coj kho vajtse Cheebtsam, feem ntau, USB.

Mus rau lwm yam nrov nta ntawm niaj hnub txais txiaj ntsim zoo:

• Cardsharing kev pab txhawb nqa kev xaiv;
