Mkhalapakati rauta ngati "nkhani" Kodi nawo: mabomba awiri kupanga mwachindunji otetezeka njira imene kenako amapezeka kulengeza. Mawu osavuta, Miracast (ndi malangizo zamakono monga pogwira ntchito ndi chithunzi ndi mavidiyo zomwe wotchuka kwambiri kuposa miyambo HDMI-pachipata, tsopano palibe chikaiko) ali ndi zomangamanga anamanga pamwamba pa Direct Wi-Fi Mabaibulo pambuyo (3.50 ndi pamwamba). Ntchito H.264 kanema psinjika amalola recreate ndi buku lenileni la zinthu posonkhanitsa deta visualizer aliyense atypical, kuphatikizapo pa nsalu yotchinga ziyerekezo.

Ubwino kuti maganizo lililonse

Ngakhale wongoyamba wosuta mosaganizira adzaitana zifukwa zingapo kufunika kwa Miracast. Choyamba, tikulankhula za chitonthozo chimene chimagwira ntchito: kuonekera kwa wina ndi mzake "pa mpweya" ndi chizindikiritso amapezeka mu nkhani ya masekondi, ndipo mogwirizana - popanda intermediaries (palibe chifukwa kugula polumikiza chingwe). Kachiwiri, zochotseka-Miracast adaputala ndi makina kuti kusintha pompa kwa lachitsanzo makamaka chipangizo sayenera - dongle sender / wolandila yokha amazindikira zambiri zojambulajambula. Komanso, pali kukhala thandizo kwa 3D pa maziko a chitetezo chonse okhutira kulengeza.

Ena mwa madalitso ena:

• kutchuka kwa anafotokoza kulankhulana muyezo mu opanga dera (zoposa 500 makampani kwambiri za kugwiritsa ntchito "kalilole wa wailesi");
• palibe kuchedwa amamvekera chizindikiro processing (mtengo wotsika chitsanzo zapamwamba lamulo ili ntchito osati kwathunthu);
• kuthekera posamutsa "katundu" kanema (FullHD);
• minimization njira zina (lilibe katundu kwambiri pa batiri pa foni / piritsi).

Miracast ndi zofooka zake

Mwatsoka, mawu "popanda zolakwika" pafupifupi zimachokeradi mu dziko la umisiri mkulu-nzeru. chakuti Baibulo watsopano wa Miracast (Android, ziyenera anati, chimodzi chabe mwa machitidwe opaleshoni ambiri amene akulumikiza likuwayenera ndi mfundo imeneyi, koma mu gawo la zikopa mafoni ulamuliro wake si chipeneko) ndi olakwika, umboni ndi:

• prohibitive mlingo wa mankhwala masking kuti alipo pa bolodi mapulogalamu, ndi "hardware" kukhazikitsa luso (palibe Logos pa ma CD ndi / kapena devaysa nyumba).

Komanso, owerenga ambiri kuwona mwayi kuti pamene ntchito Miracast-chida ali waima ntchito ochiritsira Wi-Fi-kugwirizana. A adaputala 2-njira, monga ife tikudziwira, osati onse zili ndi mafoni ndi miyala (kuchepekedwa zimawonedwa ngakhale mu gawo la nsembe umafunika). Pomaliza, mphamvu ya 30 FPS ndi 720x480 - mapurosesa mitengo wodzichepetsa lero, koma ofooka nthawi zina sapeza chidziwitso cha Visualizer (pa kanema chinsalu chachikulu akubwera ndi jerks noticeable).

Analogs ndi kusiyana kwawo lofunika

Opaleshoni machitidwe, wochezeka okonda kuti Miracast, - Android (kuyambira Baibulo 4.2 Odzola nyemba), Windows 8.1 (kwa kompyuta ndi zipangizo lamya) ndi Amazons Moto. Koma PC ndi zochokera Linux, ndiye popanda kuswa kukwaniritsa kuzindikira mokwanira mu kulunzanitsa ndi mankhwala a mbiri yabwino sadzapambana. Komabe, huck ndi zinadzala ndi zolephera ndipo akhoza sitingakumane ndi kukambirana yachibadwa pakati pa sender ndi wolandira wa zili TV. Oimira osiyanasiyana Apple samadziwa Miracast, monga "m'ndende" pansi choyambirira nsanja luso AirPlay.

Ndi Intel WiDi tinganene kuti kugwirizana muyezo kwa nthawi yaitali, anali pabwino monga chuma cha dzina chomwecho bungweli ndipo anali sakudziwika kwa zipangizo ndi mapurosesa lachitatu chipani. Koma ndi kutulutsidwa kwa Baibulo 3.5 ndi za kusintha kopambana.

Yikidwa mawaya Akhristu awiri - MHL ndi HDMI. Kusiyana kwakulu Dziwani chingwe m'munsi kukhudzana, amene si yabwino pamene gawo kulunzanitsa ndi mtendere mbendera ndi wochitachita kuwombola deta (Miracast zayamba "sags", pamene chophimba kudzifutukula kanthu-zithunzi).

Miracast pamaso pa opanga

Ngakhale sayansi ndipo ali gwero malamulo lotseguka, ma aligorivimu ake kutengerapo opanda zingwe chithunzi kwenikweni lolunjika pa angathe Windows ndi Android. N'zosadabwitsa kuti mndandanda wa opanga akubwera ndi nthawi, malo ena ambiri. N'zoona kuti pali kuchotserapo ndi dongosolo zosasangalatsa zokhudza pomwe kasamalidwe chipolopolo. Choncho, makamaka sanali amapereka mwa Miracast Windows 7 (ndi nkhani si kutsimikiza kaya ndi msonkhano kukopera kapena unsembe mapulogalamu othandiza).

The zopangidwa kwambiri kuzindikira anawona "m'chikondi" chifukwa Wi Fi-Direct ndi H.264:

• Qualcomm.
• MediaTek.
• AMD.
• Microsoft.
• Intel.

Posachedwapa ndi Miracast malo

Ganizo kukhazikitsa HDMI opanda zingwe, ndithudi, chidwi. Komabe, kuwonetsera pa yaikulu mudziwe chophimba ku foni yanu kapena piritsi si zovuta. Kodi zovuta - kupeza wamakhalidwe njira ndondomeko SMARTs. Ndipo chikutanthauza Miracast basi sinditi bwino.

Kuwonjezera mpikisano mwachindunji - AirPlay ndi Chromecast - zinthu zina mphindi zambiri "anzeru". Mwachitsanzo, amalola kutumiza kanema zili pa nsalu yotchinga zikuluzikulu n'kuyamba kusambira kudutsa menyu (popanda kusonyeza mfundo yomweyi mu mtsinje opatsirana). Chachiwiri zosasangalatsa nuance adza kwa kubwezeretsa mode - Miracast zambiri masewero kanema mapeto, osati yatikhudza mwina sensa kapena kachipangizo lamulo malo / gulu devaysa gwero (zonse conjugation analonjeza mu fimuweya latsopano, ndiye "mtulo" yamakono amaphunzira kuthimitsa ziyerekezo chophimba popanda malamulo owonjezera wosuta).

Tsopano za kufanana ndi luso DLNA. Miracast - ndi "molunjika njira: ukufalitsidwa" moyo "zithunzi nsalu yotchinga chida pa polojekiti osiyana limapezeka pa aligorivimu yayifupi popanda mfundo zoonjezera kulankhulana. Pansi DLNA chidule amabisa lonse mfundo kuphatikiza raznosortnyh. Ie zipangizo kukhazikitsa kumvana amafuna pamaso pa "wotanthauzira" (rauta). Ndipo kachiwiri, ophunzira Intaneti Living Network Alliance zitha ntchito owona, ndi awiri "bwenzi" Miracast ntchito pa galasi mfundo ( "amene amasonyeza, ndiye kudali"), ndi kuthetsa ena mavuto luso angathe kugawana mu kalunzanitsidwe akadakwanitsira.

Mapulogalamu Miracast ngakhale: Windows-Baibulo

Pa boma tsamba Microsoft chili ndi nkhani chofunika zinthu opaleshoni imene n'zotheka akabweretsa zinchito ya umisiri Miracast.

Windows 8.1 - chisanadze anaika kapena kusinthidwa ndi "zisanu ndi ziwiri" - amatanthauza chiwerengero cha amafuna osachepera. Komanso, kulengeza za applicability a muyezo kwa kulengeza Baibulo RT 8.1 ndi misonkhano Os ina.

kukonzekera kompyuta / chida cha mafoni Kuwulutsa TV zili pa polojekiti ndi

Zipangizo ndi "eyiti" pa bolodi mndandanda wa zochita kuonetsetsa ndondomeko Kuwulutsa inali mfundo ziwiri:

1. zipangizo kalunzanitsidwe (chopatsilira ndi wolandila) ali m'dera chizindikiro Kuphunzira.
2. Kutsegula "purojekitala" njira.

Ndipo pali zitsanzo zingapo linanena bungwe okhutira. Chithunzi / video, mungathe:

• ukufalitsidwa ndi mode chibwereza (munthawi yomweyo anasonyeza 2 kusonyezedwa);
• yerekezani okha poyeza zida kulandira;
• kusamutsa pokoka zinthu anakhumba kwa nsalu yotchinga kwa nsalu yotchinga.

Miracast ndi Android opaleshoni dongosolo

Ambiri zamagetsi opanga akuyesera kuti kwambiri za luso Miracast. The LG Mwachitsanzo, integrates mu mafoni ndi matelevizioni kwazaka zingapo. Musati kwanthawi kumbuyo ndi akatswiri Sony, Samsung, Panasonic - kumene ikutha Android wamkulu kuposa 4.2, muyezo akuyendera, monga iwo amati, chathunthu.

Kufunika kwa HIV wabwino zili kwachititsa chakuti thandizo la Miracast ngakhale zitsanzo anthu TV omwe ali pa msonkhano mzere mpaka 2012. njira luso anakhala HDMI pokha makiyi (chizindikiro adaputala azamagetsi). Pa nthawi, iwo zikugwira zotsimikizira ambiri makampani osiyanasiyana. Chifukwa, mankhwala kubwera ku msika, ndipo kwambiri amasiyana mtengo ndi khalidwe. Komanso, malo kukhala ndi zinchito vutoli: adaputala wina kwa mphamvu kuti amange "milatho" mkati Miracast muyezo wina alibe ndalama chilichonse kupeza "mumafanana" ndi Apple devaysa kapena kukhazikitsa "kukambirana" pa DLNA lapansi. Ndicho chifukwa musanagule zofunika kuposa peruse ndi maonekedwe thematic ndi kukaona malo boma la opanga.

Mwachidule za dongle otchuka

pa Miracast Dongle mitengo yosiyanasiyana osiyanasiyana 30-100 Cu. Pambuyo ogulidwa ndi unsembe wa adaputala pafupifupi TV aliyense okonzeka ndi HDMI-doko, akhoza olumikizidwa kwa chida cha wirelessly. Tikuyankhula zokhudza kugwirizana kuti amalola kuti kusewera "chachikulu" mavidiyo 1920x1200 mtundu.

Dongle Mocreo (.. 30-35 Cu) - kungakupatseni thandizo ndondomeko zitatu: Miracast, AirPlay ndi DLNA.

"Chinsinsi" mtundu Pythons (70-80 pa. E.), Childs kuzindikira mfundo mofanana Mocreo.

Adaputala GeekBuying (50-60 Cu ..) - amapereka galasi kulengezetsa pa ma aligorivimu Miracast ndi DNLA.

Komanso, pali malonda zilipo ndi choyambirira dongle Wi-Fi Wotsimikizika Miracast, amanoledwa pansi mtundu wina wa chizindikiro.
