Chiyambi cha Studio Transmitter Link (STL)

Kodi munamvapo za studio transmitter link kapena STL? Ndi njira yowulutsira yomwe nthawi zambiri imagwiritsidwa ntchito mu situdiyo ya digito yomangidwa mumzinda. Zili ngati mlatho pakati pa situdiyo ndi chowulutsira mawayilesi a FM, kulola kuti zomwe zili pawailesiyi zifalikire kuchokera ku studio kupita ku wailesi ya FM, ndikuthetsa vuto lakusayenda bwino kwa wailesi ya FM mumzinda. Mutha kukhala ndi mavuto ambiri ndi dongosololi. Gawoli likuwonetsani Studio to Transmitter Link kuti ikupatseni mayankho.

Ulalo wopatsira situdiyo umatchedwanso studio kuti itumize pa IP, kapena ulalo wa studio, kapena STL mwachindunji. Malinga ndi tanthauzo la Wikipedia, limatanthawuza a zida zolumikizira ma studio yomwe imatumiza mawayilesi kapena wailesi yakanema kapena kanema wawayilesi kuchokera ku situdiyo yowulutsira kapena malo oyambira kupita ku wayilesi, wailesi yakanema, kapena malo olumikizirana nawo malo ena. Izi zimatheka pogwiritsa ntchito maulalo a microwave ozungulira dziko lapansi kapena kugwiritsa ntchito ma fiber optic kapena maulumikizidwe ena a telecommunication kumalo otumizira.

Maulalo otumizira ma situdiyo amatha kugawidwa mu ma analogi studio transmitter link ndi digito studio transmitter link (DSTL).

• Maulalo otumizira ma studio a analogi nthawi zambiri amagwiritsidwa ntchito pamawayilesi akulu kapena mawayilesi akanema (wailesi kapena wailesi yakanema pamtunda kapena pamwamba pa chigawo), okhala ndi ntchito zotsutsana ndi kusokoneza komanso zotsutsana ndi phokoso.
• Ulalo wotumizira ma situdiyo a digito nthawi zambiri umagwiritsidwa ntchito pamawayilesi kapena mawayilesi akanema omwe amafunikira kufalitsa ma audio ndi makanema mtunda wautali. Ili ndi kutayika kwazizindikiro kochepa ndipo ndiyoyenera kutumizira mtunda wautali (mpaka 60 km kapena 37 miles).

Chifukwa chiyani ma studio owulutsa amatenga STL? Monga ife tonse tikudziwa, pofuna kukulitsa Kuphunzira kwa Makanema a wailesi ya FM, kaŵirikaŵiri amaikidwa pamwamba pa nsanja zoulutsira mawu pawailesi pamwamba pa phirilo. Koma ndizosatheka komanso zopanda nzeru kumanga situdiyo yowulutsa pamwamba pa phirilo. Ndipo mukudziwa, situdiyo yowulutsa nthawi zambiri imakhala pakatikati pa mzindawu. 

Mutha kufunsa: bwanji osayika chowulutsira wailesi ya FM mu studio? Limeneli ndi funso labwino. Komabe, pali nyumba zambiri pakati pa mzindawo kotero kuti zichepetse kwambiri kuwulutsa kwa wailesi ya FM. Ndizochepa kwambiri kuposa kuyika chowulutsira mawayilesi a FM pamwamba paphiri. 

Chifukwa chake, dongosolo la STL limagwira ntchito ngati kanyumba kotumizira ma audio ndi makanema kuchokera ku studio kupita ku wailesi ya FM paphiri, kenako ndikuwulutsa mawayilesi m'malo osiyanasiyana kudzera pa wailesi ya FM.

Mwachidule, ziribe kanthu analogi STL kapena digito STL, ndi zidutswa za zida zoulutsira mfundo zomwe zimalumikiza situdiyo ndi chowulutsira wailesi ya FM.

Chithunzi chotsatirachi ndi chithunzi chachidule cha Studio Transmitter Link choperekedwa ndi FMUSER. Mfundo yogwirira ntchito ya dongosolo la STL ikufotokozedwa mwachidule pachithunzichi:

• Zolowetsa - Choyamba, situdiyo imalowetsa mawu omvera pazowulutsa kudzera pa mawonekedwe a stereo kapena mawonekedwe a AES / EBU ndikuyika chizindikiro cha kanema kudzera pa mawonekedwe a ASI.

• Kuwulutsa - Chowulutsira cha STL chikalandira siginecha yomvera ndi kanema wa kanema, mlongoti wa STL transmitter utumiza masiginowa ku mlongoti wolandila wa STL mu bandi yafupipafupi ya 100 ~ 1000MHz.

• Kulandila - Wolandila wa STL alandila siginecha yomvera ndi vidiyo, yomwe idzakonzedwanso ndi zida zina zamagetsi ndikutumizidwa ku chowulutsira cha FM.

Monga mfundo yowulutsira pawayilesi, Studio Transmitter Link imawulutsa ma siginecha munjira zitatu: Kulowetsa, kuwulutsa, ndikulandilanso.

"Kodi ndingakhale ndi STL yanga?", Tamva funsoli nthawi zambiri. Popeza makina a microwave STL nthawi zambiri amakhala okwera mtengo, makampani ambiri owulutsa amasankha kubwereka makina a STL. Komabe, akadali mtengo waukulu pamene nthawi ikupita. Bwanji osagula ADSTL ya FMUSER, mupeza kuti mtengo wake ndi wofanana ndi wobwereketsa. Ngakhale mutakhala ndi bajeti yochepa, mutha kukhala ndi dongosolo lanu la STL.

Phukusi lawayilesi la digito la ADSTL lochokera ku FMUSER limakwirira situdiyo kuti itumize zida zolumikizira mawayilesi, kuphatikiza chowulutsira situdiyo ndi wolandila ndi LCD panel control system, Ultra-lightless stainless steel antenna Yagi yopindula kwambiri, zingwe za RF antenna mpaka 30m, ndi zina zofunika, zomwe zingakwaniritse zosowa zanu zosiyanasiyana:

• Sungani mtengo wanu - ADSTL ya FMUSER imatha kuthandizira mawu omvera a stereo 4 kapena digito high fidelity (AES / EBU), kupewa kukwera mtengo kogula makina angapo a STL. Imathandizanso ukadaulo wa SDR, womwe umakupatsani mwayi wokweza makina a STL kudzera pamapulogalamu m'malo mogulanso zida.

• Kumanani ndi zomwe zimafunikira ma frequency band - ADSTL ya FMUSER sikuti imangothandizira ma frequency 100-1000MHz komanso imathandizira mpaka 9GHz, yomwe imatha kukwaniritsa zofunikira zamawayilesi osiyanasiyana. Ngati mukufuna kusintha ma frequency ogwirira ntchito ndipo mwadutsa ntchito ya dipatimenti yoyang'anira kwanuko, chonde omasuka kulankhula nafe kuti musinthe mawonekedwe a ADSTL ndi kuchuluka komwe mukufuna.

• Kutumiza kwa ma siginecha apamwamba kwambiri - ADSTL ya FMUSER ili ndi magwiridwe antchito abwino kwambiri oletsa kusokoneza. Itha kufalitsa kukhulupirika kwakukulu HD-SDI zomvera ndi makanema patali. Ma audio ndi makanema amatha kufalikira ku nsanja yotumizira wailesi pafupifupi popanda kutaya kulikonse.

ADSTL ya FMUSER ndiye njira yotsika mtengo kwambiri ya Studio Transmitter Link kwa inu. Ngati mukufuna, dinani apa kuti mudziwe zambiri. 

Kodi STL System Imagwiritsa Ntchito Antenna Yamtundu Wanji?

Mlongoti wa Yagi nthawi zambiri umagwiritsidwa ntchito m'makina a STL, omwe amatha kugwiritsidwa ntchito polarization ofukula komanso yopingasa kuti apereke chiwongolero chabwino. Mlongoti wabwino kwambiri wa Yagi nthawi zambiri umakhala ndi mawonekedwe osavuta kugwiritsa ntchito pawayilesi, kupindula kwambiri, kupepuka, kukwezeka, kutsika mtengo, komanso kukana nyengo.

Kodi STL System ingagwiritse ntchito pafupipafupi bwanji?

Kumayambiriro koyambirira, chifukwa cha luso lamakono, maulendo ogwira ntchito a STL anali ochepa 1 GHz; Komabe, chifukwa cha kuwongolera kwaukadaulo wokhazikika komanso kuchuluka kwa mphamvu zotumizira makampani owulutsa, njira zotumizira zamalonda ndizokwera mpaka 90 GHz. Komabe, si mayiko onse omwe amalola makina a STL kugwiritsa ntchito ma frequency ambiri. Ma frequency operekedwa ndi FMUSER akuphatikiza 100MHz-1000MHz, 433-860MHz, 2.3-2.6GHz, 4.9-6.1GHz, 5.8GHz, ndi 7-9GHz, zomwe zingakupangitseni kuti musachepetse ndi dipatimenti yoyang'anira wayilesi yakomweko.

Kodi Ndizovomerezeka Kugwiritsa Ntchito Studio Launch Link SystemM'dziko Langa?

Yankho ndi inde, maulalo otumizira ma studio ndi ovomerezeka m'maiko ambiri. Komabe, m'maiko ena, kugwiritsa ntchito zida zolumikizira ma studio kumachepetsedwa ndi dipatimenti yoyang'anira kwanuko. Mukuyenera kupereka ziphaso zoyenera ku dipatimenti yoyang'anira kuti mupeze chilolezo chogwiritsa ntchito.

Kodi Ndingadziwe Bwanji Ngati Ulalo wa Studio Transmitter Ndiwololedwa?

Musanagwiritse ntchito kapena kugula zida zolumikizirana ndi situdiyo, chonde onetsetsani kuti mwafunsira ku dipatimenti yoyang'anira wailesi yakumaloko kuti akupatseni chilolezo chogwiritsa ntchito makina a STL. Gulu lathu la akatswiri a RF lidzakuthandizani pazotsatira zopezera laisensi - kuyambira pomwe zida zimaperekedwa mpaka kugwira ntchito bwino komanso kotetezeka.

Chifukwa chakuchulukirachulukira kwamizinda padziko lonse lapansi, dongosolo la STL lakhala gawo lofunikira kwambiri pama studio owulutsa. Monga mlatho pakati pa makampani owulutsa ndi ma wayilesi a FM, imapewa zovuta zingapo monga kusokoneza ma siginecha, nyumba zambiri, komanso zoletsa kutalika mumzinda, kuti makampani owulutsa azitha kugwira ntchito moyenera. 

Kodi mukufuna kuyambitsa makina anu a STL? Monga akatswiri opanga zida zamawayilesi, FMUSER imatha kukupatsirani situdiyo yapamwamba komanso yotsika mtengo ya ADSTL kuti muzitha kutumizira zida zolumikizira. Ngati mukufuna kugula kachitidwe ka ADSTL kuchokera ku FMUSER, chonde omasuka kutilumikizana nafe.
