Pa Julayi 25, 2019, popanda chenjezo, State Commission on Radio Frequencies (SCRF) idapereka mulingo wapanyumba wa RAVIS wa 65,8-74 MHz ndi 87,5-108 MHz pokonzekera kuwulutsa kwawayilesi pakompyuta. Tsopano gawo lachitatu lawonjezeredwa pa kusankha kwa miyezo iwiri yosakhala yabwino kwambiri.
Ku Russian Federation kuli bungwe lapadera lomwe limayang'anira kugawa ma wailesi omwe alipo pakati pa omwe akufuna kuzigwiritsa ntchito. Ndondomeko zamabizinesi amakampani komanso kupezeka kwa njira zosiyanasiyana zoyankhulirana ndi zingwe zopanda zingwe kwa anthu zimatengera zisankho zake.
Kuyambira mkatikati mwa zaka za m'ma XNUMX, pakhala pali ulesi kukonzekera kusintha kwa digito wailesi ndi wailesi yakanema. Ndipo ndondomekoyi ikatalika, chodabwitsa kwambiri ndi njira ya SCRF pankhaniyi (ngati ilipo).
16 April 2018 zaka pangani wailesi ya digito pama frequency 175,872–228,128 MHz molingana ndi muyezo wa DAB+ (nthawi zambiri, mndandandawu umapangidwira TV, koma waperekedwa pawailesi ya digito). Nthawi yovomerezeka ya chilolezo ndi zaka 10.
zaka 11 September 2018 pangani wailesi ya digito pama frequency 65,9-74 MHz ndi 87,5-108 MHz molingana ndi muyezo wa DRM+. Nthawi yovomerezeka ya chilolezo ndi zaka 10.
Chifukwa chake, ma frequency onse omwe amapezeka adagawidwa pakati pamiyezo iwiri yopikisana. Wina angaganize kuti izi ndizofunikira pama projekiti oyesa. Komabe, zisankhozi zidapangidwa potengera zotsatira za iwo. Ndiko kuti, chinali kwenikweni chilolezo chopanga machitidwe awiri opikisana ndi osagwirizana.
Chithunzi: kuchokera patsamba
Ndipo mwadzidzidzi, pa Julayi 25, 2019, popanda chenjezo, osiyanasiyana 65,8–74 MHz ndi 87,5–108 MHz pokonzekera kuwulutsa kwa digito. Komanso kwa zaka 10. M'mbuyomu, ma frequency awa adapangidwira DRM+, yomwe dipatimentiyo .
Ndiye ndi chilombo chanji, RAVIS? Tiyeni tiyambe ndi manambala owuma ndi mawu opanga mapulogalamu:
Chithunzi: kampani yopanga mapulogalamu "Sad-Com"
Dongosolo la RAVIS limapereka kutumiza kwamavidiyo, zomvera ndi zina zotsatizana nazo pakulandila kokhazikika komanso kwamafoni. RAVIS imapereka:
- kuonjezera kuchuluka ndi mtundu wa mapulogalamu otulutsa mawu (mapulogalamu 10-15 apamwamba kwambiri pawayilesi imodzi);
- kukhazikitsidwa kwa mautumiki atsopano, kuphatikizapo kuwulutsa kwamavidiyo, ndi kulandirira kokhazikika kwa mafoni;
- kuchepetsa kugwiritsa ntchito mphamvu zowulutsira;
- kukulitsa malo ofikira a transmitter imodzi, kuthekera kopanga ma netiweki ang'onoang'ono ndi akulu amtundu umodzi.
Choncho, chikhalidwe chapakhomo chimaphatikizapo kuphatikiza mwayi wofalitsa wailesi ya digito yokhala ndi phokoso lapamwamba komanso TV yapakatikati ya digito (kanema wa 900 kbit / s, m'malo mwa 15 audio mitsinje pa njira). Mwachilengedwe, pali mwayi wofalitsa mauthenga ndi mauthenga aukadaulo, zithunzi zazithunzi.
Makhalidwe a mulingo womwe akufunsidwa amawoneka bwino kwambiri, abwinoko kuposa njira zina (). Mwa njira, Madivelopa sanaiwale kuwonetsa ntchito yawo mu ulemerero wake wonse motsutsana ndi maziko otumbululuka a omwe akupikisana nawo.
Chithunzi: kampani yopanga mapulogalamu "Sad-Com"
Anthu ofunikira a Sad-Com, kampani yomwe idapanga muyezo wa RAVIS, ndi Victor ndi Alexander Dvorkovich. Achibale a Prime Minister wakale Arkady Dvorkovich (tsopano wapampando wa Skolkovo Foundation, wapampando wa board of director a Rusnano). A Dvorkovichs ali ndi 2/3 ya kampaniyo ndipo akutenga nawo mbali pachitukuko. Mwa njira, kampani ya Sad-Com ndi wokhala ku Skolkovo.
Mwachiwonekere, ndi Sad-Com yomwe ikukonzekera kukhala wotsogola kapena wopanga yekha wamagetsi ofunikira pokonzekera kuwulutsa ndi kulandira zikwangwani molingana ndi muyezo watsopano. Chifukwa chake, pamodzi ndi mabizinesi ankhondo, zida zoyeserera kapena zazing'ono zidakhazikitsidwa kale (kwa ine ndekhamtengo wa wolandira ndi $ 100 ndi chiyembekezo chochepetsera ku $ 40-50 mu kupanga kwakukulu). Palibe zambiri za momwe luso laukadaulo lazinthu zimapangidwira pamtengo uwu. Komanso kuthekera ndi chikhumbo choyambitsa chithandizo cha muyezo ndi opanga akunja ogula zamagetsi.
Zithunzi: kampani yopanga mapulogalamu "Sad-Com"
Zotsatira zomwe zikuyembekezera msika wawailesi ndizosangalatsa. Choncho, akatswiri onse amavomereza mogwirizana kuti osewera sali okonzekera mpikisano wowonjezereka, womwe udzachitike chifukwa cha kuchepa kwakukulu kwa mtengo wolowera. Makanema mazana angapo aulere komanso otsika mtengo owulutsira pawailesi, komanso ma TV angapo angapo omwe angabwere chifukwa chakusintha kwawayilesi ya digito, achepetsa zotsatsa zotsatsa. Choncho, mu kotala loyamba Mu 2019, kuchuluka kwa zotsatsa pawailesi kudafikira ma ruble 3,4 biliyoni.
Panthawi imodzimodziyo, akatswiri sanenapo kanthu za mwayi umene udzachitike pakubwera kwa teknoloji yatsopano: kutsatsa komwe kumayang'aniridwa, mitundu yatsopano yotsatsa (mu zithunzi, zolemba ndi masilaidi), kukulitsa omvera onse pokweza mawu ndi mitundu yosiyanasiyana ya mawu. masiteshoni. Kuthekera kopanga njira ina yowulutsira pa TV, yoyang'ana madalaivala komanso kuthekera kosintha zomwe zikuwulutsidwa kwanuko, kumawonekanso kochititsa chidwi kwambiri.
Komabe, palinso zotulukapo zokayikitsa - kuwonekera kwa ogwiritsa ntchito pawayilesi. Chifukwa chake, muyezo umatengera kuwulutsa kwa ma multiplex (mlongoti umodzi ndi zida zina zimawulutsa mawayilesi 10-15 nthawi imodzi). Mawayilesi apawokha mwina sangagule ndi kukonza zida zonse zomwe zimatha kuulutsa mapologalamu 15 pomwe amangofunikira imodzi kapena ziwiri. Mwachidziwikire, padzakhala ogwira ntchito omwe ali ndi ma network otumizirana ma transmitter ndikubwereketsa ma radio sipekitiramu, omwe amabwereketsa bandiyo kumawayilesi. Ndipo asankhanso malamulo ovomerezeka (osavomerezeka) ku netiweki yowulutsa.
Kodi mumagwiritsa ntchito wailesi pafupipafupi bwanji? Kodi mwakonzeka kusinthiratu olandila anu ngati RAVIS itengedwa, kapena mungafune kusinthana ndi DAB+ (mwinamwake yathandizidwa kale ndi makina anu)?
Ogwiritsa ntchito olembetsedwa okha ndi omwe angatenge nawo gawo pa kafukufukuyu. chonde.
Zatsopano zochulukirachulukira zimadalira kulumikizana opanda zingwe ndi kuwulutsa, monga IoT. Ndi mitu yanji ya pa intaneti ya Zinthu yomwe mukuyembekezera kudzasindikizidwa posachedwa?
ML ya IoT yonse
ML ya (mwaukadaulo) makina ocheperako
Chitetezo cha machitidwe a IoT
Nyumba yanzeru ya DIY
Ogwiritsa 40 adavota. Ogwiritsa ntchito 27 adakana.
