Miracast - chii here? Wireless hutachiwana zvenhau chiratidzo

Yepamusoro Wireless Multimedia chiratidzo kubva uropi kune mumwe devaysa mudziyo (TV, purojekita, kumhanyira mutambi, etc ...) - izvi ndizvo chaizvo zviri shure Miracast izwi. Michina Uyu chepamutemo musika pavakanzwa "namahwindo" nevakangwara zvinhu Apple uye Intel, kureva kuti nhaka nenhungamiro AirPlay uye WiDi, asi zviri pasi kushanda siyanei algorithms. Sezvo hwaro mureza wakatorwa mikana Wi-Fi Direct. Naizvozvo, nzira mashoko kubva nhau renderer kuti chete mbiri points. Router-murevereri mubishi rokushandura haisi zvematongerwo - yatumira uye mugamuchiri chokuita zvakananga.

Miracast. Chii chishamiso ichi?

Chete kodzero kuti vanozivikanwa (zita zvizivikanwe zvizere - Wi-Fi vaipupurirwa Miracast) kushamwaridzana ane Wi-Fi Alliance. Zvisinei, chero anokosha Logos kana abbreviations kuti ndezve mishonga kutsigira zvemichina haako. The chinyorwa «WiFi Miracast» Kazhinji aishanda ari mudziyo, vakapfuura kurutivi advertising nzira zvinoenderana zvinodiwa Ratidza bvunzo urongwa.

The chinangwa chikuru yakanga akagadzira sezvinotevera :. "Kuti ave nechokwadi goho kuti vezvenhau tigutsikane kubva PC tarisisa kana Mobile Gadget kuratidza pamadziro makuru pasina kushandisa waya uye zvekunze network" Kunyanya Kumikidzo chatingatevedzera akagamuchira chiratidzo.

Nhasi mumwe mushandisi ndiye "akangwara" devaysa (chero kuti Os kutsigirwa Miracast mureza) anogona synchronize mudziyo wavo ane TV / purojekita uye kushanda pamwe pakafunuka mufananidzo pasina kuisa zvimwe software.

Muongororo yekutanga unhu

Chinokosha Panobva zvigadzirwa - kushanda algorithms Wi-Fi Direct: Miracast-adapteri kuti plugs kupinda HDMI chengarava-Conjugate chikwata (kana inopiwa ne "simbi" urongwa dzakawanda), amirire chikamu musha paIndaneti uye anovaka zambuko ane akarembedzwa mushamarari. Uyezve, Itu-T H.264 youduku chiratidzo pano harioneki senzira kuchinjana mafaira, uye somunhu nomazviri kutakura vezvenhau omumasherufu Kamudzira (purogiramu anotumwa uye akagamuchira muchimiro sezvazviri).

Panguva zvekuratidza Miracast (zvakaitika chaizvo muna September 2012 - hakuna tsaona: mu asingasviki 2 months mabikirwo kwave vakagamuchirwa nokuda yoku- uchishandisa hurongwa Android, uye, naizvozvovo, rakaiswa kwete zvigadzirwa Google), paiva kupfuura makumi mashanu vakatsigira zvisarudzo: 17 - CEA, 29 - VESA, 12 - vanonzi runhare. Pakati kucherechedzwa ruzha mitemo - maviri-gwara LPCM, «redhiyo 5.1» AC3 uye ACC.

Kuti uwane mamwe mashoko pamusoro kubatana kwacho

Danho nedanho activation Miracast nzira (zviri pamwe atova pachena) kunosanganisira matanho akawanda. Tinofanira kuita nenzira:

1. Batidza PC / Smartphone / "Handheld".
2. Batidza mugamuchiri 'Data (kana TV chidzitiro mharidzo).
3. Ipa zvose mano unoenderana munhu preset chirongwa.

Sarudza uye kumhanya chairo faira iri kopi muoti, ari kuratidza chidzitiro pasi tarisisa nhau receiver.

Muyananisi Router mu "hurukuro" akadaro haabatanidzwi: mano maviri anoumba zvakananga yakachengeteka mugero pamusoro vakazochinja kunoitika nhepfenyuro. Zviri nyore, Miracast (zviri muzvigadzirwa mirayiridzo sezvo muchimiro basa ne pikicha uye mavhidhiyo mashoko ichava yakakurumbira kupfuura chinyakare HDMI-pasuo, yava hapana mubvunzo) chinonzi mapurani yakavakwa pamusoro Wi-Fi Direct Papera shanduro (3.50 uye pamusoro). Vakashandisa H.264 vhidhiyo compression ambotirega kuti recreate chaiyo kopi date zvinhu chero atypical visualizer, kusanganisira pamusoro fungidziro chidzitiro.

Kubatsirwa kunoitwa nomumwe

Kunyange munhu asina ruzivo User pasina kufunga kuti mudane zvikonzero zvinoverengeka nokuda kudiwa Miracast. Chekutanga, tiri kutaura pamusoro kushanda nyaradzo: zvinoonekwa vakataurirana "pamusoro mhepo", ne kuzivikanwa kunoitika panyaya mumasekonzi, uye kukurukurirana - pasina vanozoshanda (haritsvaki kutenga unobatanidza waya). Chechipiri, bvisika-Miracast adapteri iri zvoga kuitira kuti uchida kugadziridza kuti imwe muenzaniso mudziyo haafaniri - dongle yatumira / mugamuchiri pacharo anoona mashoko kwakajeka. Uyezve, pane kuva rutsigiro 3D pamusoro pakanyorwa zvizere kudzivirirwa nhepfenyuro tigutsikane.

Nezvimwe zvinobatsira:

• vanhu vakawanda vanorondedzerwa kukurukurirana mureza munharaunda vaburitsi (vanopfuura 500 makambani nezvezvaiitwawo Implementation ari "girazi kuti nhepfenyuro");
• hapana pachena nokunonoka chiratidzo kubudiswa (yakaderera mutengo womuenzaniso midziyo mutemo uyu rinoshanda kwete zvakazara);
• mukana tama "inorema" vhidhiyo (FullHD);

Miracast aro utera

Zvinosuruvarisa, mashoko "pasina zvaunokanganisa" kushanda hariwanikwi munyika mukuru-njere michina. Chokwadi chokuti kuitika shanduro Miracast (Android, inofanira akati, rinongova chimwe chezvinhu zvakawanda anodawo hurongwa kuti vanobatanidza kutapwa kwavo mureza uyu, asi chidimbu kubva Mobile amatenhe ayo kutonga hakusi mubvunzo) akaminama, runoratidzwa:

• achiri simba kugarisana (dzimwe nguva mamiriro "zvinotarisirwa kubatana ..." unoratidzwa pamusoro chidzitiro, asi kuzivikanwa hwokushanda uye haagoni kuwana musoro arambe);
• kutsigira kunonyanyisa chisarudzo pa 1920x1200, paaikura kudiwa 4K;
• kushandiswa proprietary H.264 codec;
• prohibitive mwero masking zvinogadzirwa kuti varipo mungarava software, uye "Hardware" ezvidzidzo technology (hapana rokuti logos pamusoro kavha uye / kana devaysa redzimba).

Uyewo, vanozvishandisa zhinji ona kuvamirira pakuti paaishandisa Miracast-Gadget anomiswa nokushanda kwakajairika Wi-Fi-kubatanidza. A 2-gwara adapteri, sezvo tichiziva, kwete vose vakapakata smartphones uye mahwendefa (dhefisiti iri kuchengetwa kunyange chidimbu kubva shoma zvinopiwa). Pakupedzisira, simba rinomutsa 30 the uye 720x480 - mwero prices nhasi, asi simba processors kunyange dzimwe nguva regai kuwana kunzwisisa pamusoro chikamu Visualizer (iri hombe vhidhiyo chidzitiro kunouya kuoneka jerks).

Analogs uye kusawirirana kwavo dzinokosha
