Wailesi yolumikizana FM, Broadcast wa FM Broadcast, wolumikizira / wophatikiza FM wotumizira, nthawi yotumiza FM kutulutsa / kusewera, pafupipafupi FM / wailesi:

A FM Single Frequency Network ndi njira yolumikizira komwe ma FM-ma transmitters osiyanasiyana amatumiza ma audio pafupipafupi komanso nthawi yolingana. Ma wailesi a digito ngati DVB-T / T2 komanso ma analog AM ndi ma radio radio akutha kugwiritsa ntchito mwanjira imeneyi. Ubwino wa SFN ndikugwiritsa ntchito bwino mawonekedwe a pafupipafupi, kulola kuchuluka kwa mapulogalamu a wayilesi ndi TV kuti athe kufalitsa. Chitsanzo cha ukadaulo uwu ndi ma frequency- komanso nthawi yolumikizirana ndi FM ma transmitter unyolo mumisewu yayikulu.

Vuto limodzi pakuchita bwino kwa dongosololi ndikolondola kwa nthawi yayitali kwambiri (chizindikiritso cha mawu, kusokonezedwa) kwa chizindikirocho.

Wotulutsa mawu padziko lonse lapansi akugwiritsa ntchito mitundu yosiyanasiyana yogawa (ASI, E1, satellite, IP) kukonza redundancy, kukhala wosiyana kwambiri komanso kusunga ndalama.

Zomwe zimafalitsidwa kuchokera ku transmitter ya FM, ngakhale chakudya chogwirizanitsidwa bwino kudzera pa E1, chimapangitsa kuchedwa. Kuchedwa kosasunthika kwa paketi ya IP-feed (Jitter) kapena satellite feed kumatha kuyambitsa kuchedwa kwambiri komwe kumapangitsa kulumikizana kwamtundu wa FM kukhala kovuta kwambiri.

Zosakanikirana Njira zamachitidwe imapangitsa kuti chizindikiro chanu chikufanane ndendende kudzera munjira zoperekera pa internet-SFN network.

Mukungofunika kuwonjezera System Inserter muzomwe mumapereka ndikumapereka ma sign a 1pps pama station onse. Katswiri wathu Receiver / Decoder akuwunika ma siginolo ndikugwirizanitsa bwino siginecha ya Audio ku Stereo ndi RDS Encoder. Sizikupanga kusiyana kuti ndi magawo ati omwe amagwiritsidwa ntchito ngati E1, IP kapena satellite kapena ngati chilichonse mwamafayilo awa akusankhidwa pazosunga zobwezeretsera chilichonse. Izi ndizofunikira kwambiri pakufalitsa kwa SFN chifukwa siginecha yoyendetsa ndege imayenera kulumikizidwa kale chimodzimodzi.

Njira zinanso zidzakhala kulumikizana kwa Encoders ndi Transmitters omwe amafalitsa chizindikirocho kumapeto.
