Miracast waa mid ka mid ah tiro ka mid ah heerarka bandhiga wireless. Haddii aad leedahay qalabka Miracast iyo bandhigay, waxaad soo diri kartaa signal video mid ka mid ah oo kale, iyada oo aan baahida loo qabo cable  HDMI dheer.^(HDMI)

Ma u muuqataa mid aad u fiican? Dhibaatadu waxay tahay, ficil ahaan, Miracast waxay tartan kula jirtaa heerar kale oo badan oo la mid ah. Tani waxay ka dhigan tahay in dad badan oo isticmaala aysan hubin inay isticmaali karaan Miracast ama haddii ay tahay xitaa tignoolajiyada soo bandhigida wireless-ka ee saxda ah in la isticmaalo.

Waa maxay Miracast?^{(What Is Miracast?)}

Miracast waa halbeeg lagu qeexay isbahaysiga WiFi^{(WiFi Alliance)} , taas oo macnaheedu yahay in xudunta u ah, ay isticmaasho tiknoolajiyada WiFi^{(WiFi technology)} . Gaar ahaan, waxay isticmaashaa WiFi Direct , kaas oo abuuraya isku xirka WiFi ee u dhexeeya laba qalab iyada oo aan loo baahnayn router ama meel kale oo laga galo si uu u ciyaaro qaybta dhexdhexaadiyaha.

In ka badan in xidhiidhka wireless xogta video ah waxaa loo diraa qaabka H.264^{(H.264 format)} . Taasi waa heerka ugu caansan ee fiidiyoowga HD maanta. Si rasmi ah, Miracast waxay taageertaa xallinta ilaa 1080p, oo sidoo kale loo yaqaan "HD oo buuxa". Xagga dhawaaqa, halbeeggu waxa uu sidoo kale taageeraa 5.1 Surround Sound .

Haddii ay jirto bandhig Miracast ah oo kala duwan, waxa kaliya oo ay tahay inaad sameyso waa inaad u doorataa muuqaal ahaan oo ku tuur warbaahintaada. Quruxda Miracast waa in wax kasta oo laba qalab shahaado xamili doonaa dhammaan faahfaahinta hoos-the-hood ee xidhiidhka oo aad kaliya heli kartaa on shaqadaada ama madadaalada.

Waa ayo Tartamayaasha Miracast?^{(Who Are Miracast’s Competitors?)}

Miracast waxaa la sii daayay 2012, laakiin maanta waxaa jira teknoolojiyad kale oo badan. Labada door ee ugu caansan waa Google Cast iyo Apple's Airplay . Waxa kale oo jira heerka Intel's WiDi ( Wireless Display ), kaas oo bixiya waxqabad awood u leh codsiyada daahsoon ee hooseeya sida VR ( Xaqiiqda Virtual^{(Virtual Reality)} ). Heerarkani maaha kuwo la wada shaqayn karo. Si kale haddii loo dhigo, qalabkaaga Miracast ma doonayo in uu la hadlo qalab Airplay Apple^{(Apple Airplay)} ah. 

Nasiib darrose, sannado ka dib markii Miracast la bilaabay, weli uma ekayn kuwo si gaar ah ugu dhow in la haysto hal halbeeg caalami ah ama tignoolajiyada bandhigga wireless.

Yaa Taageera Miracast?^{(Who Supports Miracast?)}

Qalab uu kula shaqeeyo Miracast , waxay u baahan tahay qalabka saxda ah iyo software labadaba. Marka, in kasta oo laga yaabo inaad haysato qalab ku shaqeeya nidaamka hawlgalka ee ku habboon, waxaad sidoo kale u baahan tahay silikoon sax ah oo ka hooseeya daboolka si uu u shaqeeyo.

Taageerada Miracast^(Miracast) waxaa lagu dhisay gudaha Windows tan iyo nooca 8.1 iyo Windows 10 wali waxay taageertaa Miracast sida qalabka wax lagu duubo iyo qaataha labadaba.

Dhinaca Apple ee adduunka xisaabinta, ma heli doontid wax taageero Miracast ah. macOS iyo iOS waxay u isticmaalaan Airplay inay yihiin dooqa kaliya ee la dubay. Waxaa jiray dhowr hab-socod oo software ah sannadihii la soo dhaafay, laakiin khibradeena kuwanu waxay ahaayeen kuwo aan la isku halayn karin oo ay si liidata u fuliyeen.

Taageerada Linux^(Linux) way jirtaa, laakiin ma muuqato wax horumar ah oo ka dambeeya. MiracleCast iyo Wireless Display Software ee Linux waa labada ikhtiyaar ee inta badan lagu xuso halkan.

Isticmaalayaasha Android^(Android) waxay sidoo kale helayaan boorso isku dhafan. In muddo ah, taageerada MiraCast waxaa lagu dubay Android lafteeda, laakiin laga bilaabo Android 6.0 wixii ka dambeeyay taageeradaas way tagtay. Si kastaba ha noqotee, kuwa sameeya aaladaha Android waxay dooran karaan inay dib ugu soo celiyaan qalabka Miracast hardware iyo taageerada software. 

Markaa haddii aad rabto in aad ogaato in qalabkaaga Android uu la shaqayn doono bandhiga MiraCast , waa in aad eegtaa dukumeentiyada mishiinkaas gaarka ah. 

Qalabka Miracast^{(Miracast Devices)}

Waa maxay noocyada aaladaha ay yihiin aaladaha MiraCast ? Mabda 'ahaan qalab kasta oo soo saari kara fiidiyoow waxaa suurtagal ah in lagu qalabeeyo tignoolajiyada MiraCast . Ficil ahaan, waa wax aad u qurux badan waxaad filan lahayd. Tablets, smartphones, laptops, desktop-yada iyo aaladaha kale ee xisaabinta caadiga ah sidoo kale waxay noqon karaan Miracast-certified . 

Mararka qaarkood taageerada Miracast waxaa lagu dari karaa iyada oo loo marayo cusboonaysiinta software ka dib, laakiin taasi waxay noqon doontaa ilaa soo saaraha qalabka.

Miracast Dongles

Maxaa dhacaya haddii aad haysato bandhig aan lahayn taageerada MiraCast ? Akhbaarta wanaagsan ayaa ah in tani ay tahay arrin aad u fudud in la xalliyo oo aysan ku lug lahayn iibsashada bandhig cusub. Waxa kaliya ee aad u baahan tahay inaad sameyso waa inaad iibsato MiraCast dongle oo ku xidh mid ka mid ah dekedaha HDMI ee muuqaalkaaga. 

Waxa runtii ugu fiican tan waa in aad qaadan karto dongle-kaaga, si aad ugu xidhiddo bandhig kasta oo meeshaad u socoto. Tusaale ahaan, waxaad ku xidhi kartaa projector-ka shirkadda marka aad rabto inaad samayso bandhig iyo maadaama MiraCast ay isticmaasho xidhiidh toos ah uma baahnid inaad ka walwasho isticmaalka shabakada wirelesska ee deegaanka.

Bandhigyada Miracast^{(Miracast Displays)}

Bandhigyada qaarkood waxay leeyihiin qalab MiraCast ah oo isla markiiba lagu dhex dhisay. Tani waxay ka dhigan tahay inaadan u baahnayn inaad sameyso wax gaar ah si aad sawirka uga tuurto aaladda Miracast . Marka agagaarka bandhigga Miracast , waa in ay ka muuqataa liiska bartilmaameedyada la heli karo ee qalabka isha.

Qaadayaasha Software-ka MiraCast^{(MiraCast Software Receivers)}

In lagu shahaado sida aaladda Miracast waxay la macno tahay in gacanta lagu hayo labada qalab ee saxda ah iyo agab software, laakiin taasi macnaheedu maaha in xalalka MiraCast ay had iyo jeer ku xidhan yihiin qalab gaar ah. 

Tusaalaha ugu fiican ee tan waxaa laga yaabaa inay tahay Airserver Universal ee PC^{(Airserver Universal for PC)} , qayb cajiib ah oo software ah oo u shaqeysa sidii soo dhaweyn caalami ah oo loogu talagalay MiraCast , Google Cast iyo Apple AirPlay . Taasi waxay la macno tahay in aad software-ka ku rakibi karto laptop-ka, ku xidhi karto projector ama bandhig kale oo weyn, oo aad muraayada wax ku ool u noqon karto qalab kasta oo ay dadku la soo baxaan.

MiraCast ma sugan tahay?^{(Is MiraCast Secure?)}

Ammaan aad u wanaagsan - oo ku saabsan sida WiFi run ahaantii ammaan u ah. Taasi waa sababta oo ah MiraCast waxay isticmaashaa borotokoolka amniga ee ^{(security protocols)}WiFi casriga ah . Tani waxay ka dhigeysaa mid aan macquul ahayn in qof uu awood u leeyahay inuu si fog uga fiirsado gudbinta. 

99% dhammaan isticmaalayaasha amniga lagu dhisay MiraCast waa wax fiican. Haddii, si kastaba ha ahaatee, aad u isticmaaleyso inaad u soo bandhigto qorshooyinka sirta sare ee DARPA waxaa laga yaabaa inaad rabto inaad si fudud u isticmaasho fiilada HDMI .

Hoos u dhaca Miracast^{(The Downsides Of Miracast)}

MiraCast waa mid aad u adag oo fudud in la isticmaalo tignoolajiyada muraayada-shaashada, laakiin waxa ay leedahay hoos-u-dhacyo dhowr ah. Hal shay, halbeeggu ma qeexayo nooc kasta oo ah heerka ugu yar ee daahitaanka. Tani waxay ka dhigan tahay in haddii aad haysato codsi (sida ciyaar ama demo is-dhexgal) oo u baahan heerar daahitaan hooseeya, ma jirto dammaanad qaadiskaaga gaarka ah ee MiraCast^(MiraCast) inuu ku fiicnaan doono.

MiraCast sidoo kale ma haysato wax taageero ah codsiyada maqal-kaliya, markaa uma diri kartid muusik ama macluumaad kale oo cod ah qaataha MiraCast . Maaddaama wax walba ay leeyihiin Bluetooth maalmahan, wax macno ah ma laha intaas oo dhan. Si kastaba ha ahaatee, waa xaddidaad mudan in wax laga ogaado.

Dhibka kale ee ugu weyn ee MiraCast waa inaad kaliya u isticmaali karto inaad muraayadda qalabka ku sawirto. Iyadoo AirPlay , tusaale ahaan, waxaad yeelan kartaa bandhiga wireless u dhaqmo sidii kormeeraha labaad halkii muraayad. Tani waa mid faa'iido leh marka laga eego dhinaca wax soo saarka iyo marka laga eego aragtida bandhigga.

Miracast wax ma leedahay?^{(Does Miracast Matter?)}

Markii ugu horreysay ee Miracast la sii daayay waxay dareemaysay kacaan, laakiin xaqiiqadu waxay tahay in Miracast ay la wareegeen labada AirPlay iyo Google Cast . Tan iyo markii dunida qalabka mobile ayaa si fiican u kala qaybsantay u dhexeeya macruufka iyo Android , waxa ay u muuqataa in taageerada Miracast waa wax yar ka maqan. 

Haddii aad hore u dhacday inaad leedahay qalabka Miracast oo aad leedahay bandhig, ma jiraan wax khalad ah in aad ka faa'iidaysato. Si kastaba ha noqotee, ilaa Miracast ay hesho casriyeyn la taaban karo mooyaane, ma jirto sabab gaar ah oo lagu raadiyo tignoolajiyadan midkoodna.

HDG Explains : What Is Miracast?

Miracast is оne of a number of wireless displаy standards. If yoυ have a Mіracast device and display, you can send a video signal from one to the other, without the need for a long HDMI cable. 

Sounds pretty good right? The problem is that, in practice, Miracast is in competition with lots of other seemingly similar standards. This means that plenty of users are unsure of whether they can use Miracast or if it’s even the right wireless display technology to use.

What Is Miracast?

Miracast is a standard defined by the WiFi Alliance, which means that at its core, it uses WiFi technology. Specifically, it uses WiFi Direct, which creates a WiFi connection between two devices without the need for a router or other access point to play the part of middleman.

Over that wireless connection video data is sent in the H.264 format. That’s the most common HD video encoding standard today. Officially, Miracast supports resolutions up to 1080p, also known as “Full HD”. In terms of sound, the standard supports 5.1 Surround Sound as well.

If there’s a Miracast display in range, all you have to do is select it as a display and cast your media to it. The beauty of Miracast is that any two certified devices will handle all the under-the-hood details of the connection and you can just get on with your work or entertainment.

Who Are Miracast’s Competitors?

Miracast was released in 2012, but today there are plenty of alternative technologies. The two best known alternatives are Google Cast and Apple’s Airplay. There’s also Intel’s WiDi (Wireless Display) standard, which offers performance with potential for low-latency applications like VR (Virtual Reality). These standards are not interoperable. In other words, your Miracast device is not going to talk to an Apple Airplay device. 

Sadly, years after Miracast was launched, we still don’t seem particularly close to having a single universal standard or wireless display technology.

Who Supports Miracast?

For a device to work with Miracast, it needs both the right hardware and software. So, although you may have a device that runs a compatible operating system, you also need the right silicon under the hood for it to work.

Miracast support has been built into Windows since version 8.1 and Windows 10 still supports Miracast as both caster and receiver.

On the Apple side of the computing world, you won’t find any Miracast support. macOS and iOS uses Airplay as the only baked-in choice. There have been a few software workarounds over the years,but in our experience these have been unreliable and performed poorly.

Linux support does exist, but there doesn’t seem to be any driven development behind it. MiracleCast and Wireless Display Software for Linux are the two oft-cited options here.

Android users get a mixed bag as well. For a time, MiraCast support was baked into Android itself, but from Android 6.0 onwards that support is gone. However, individual Android device makers can choose to put Miracast hardware and software support right back into those devices. 

So if you want to know if your Android device will work with a MiraCast display, you’ll have to look at the documentation for that specific machine. 

Miracast Devices

What sorts of devices are MiraCast devices? In principle any device that can generate video could potentially be equipped with MiraCast technology. In practice, it’s pretty much what you’d expect. Tablets, smartphones, laptops, desktops and other common computing devices can also be Miracast-certified. 

Sometimes support for Miracast can be added via a software update later, but that would be up to the hardware manufacturer.

Miracast Dongles

What if you have a display that doesn’t have MiraCast support built in? The good news is that this is a pretty simple issue to solve and it doesn’t involve buying an entirely new display. All you need to do is purchase a MiraCast dongle and plug it into one of the HDMI ports on your display. 

The really nice thing about this is that you can take your dongle with you, so that you can connect it to any displays at your destination. For example, you could hook it up to the company projector when you want to do a presentation and since MiraCast uses a direct connection you don’t have to worry about using the local wireless network.

Miracast Displays

Some displays have MiraCast hardware built right into them. This means you don’t have to do anything special in order to cast the image from a Miracast device. When in the vicinity of a Miracast display, it should show up in the list of available casting targets on the source device.

MiraCast Software Receivers

To be certified as a Miracast device means having both the right hardware and software resources on hand, but that doesn’t mean MiraCast solutions are always tied to specific hardware. 

The best example of this is probably Airserver Universal for PC, an amazing piece of software that acts as a universal receiver for MiraCast, Google Cast and Apple AirPlay. That means you can install the software on a laptop, connect it to a projector or other large display, and mirror just about any device people show up with.

Is MiraCast Secure?

Pretty secure – about as secure as WiFi in fact. That’s because MiraCast uses the same security protocols as modern WiFi. This makes it pretty unlikely that someone will have the ability to snoop on the transmission remotely. 

For 99% of all users the security built into MiraCast is just fine. If, however, you’re using it to present top secret plans to DARPA you may want to simply use an HDMI cable.

The Downsides Of Miracast

MiraCast is a pretty solid and simple to use screen-mirroring technology, but it does have a few serious downsides. For one thing, the standard doesn’t specify any sort of minimum latency standard. This means that if you have an application (such as a game or interactive demo) that needs low latency levels, there’s no guarantee your specific MiraCast setup will be good enough.

MiraCast also doesn’t have any support for audio-only applications either, so you can’t just send music or other sound information to a MiraCast receiver. Since most everything has Bluetooth these days, it doesn’t matter all that much. However, it’s a limitation worth knowing about.

The other major downside of MiraCast is that you can only use it to mirror a device screen. With AirPlay, for example, you can have the wireless display act as a second monitor rather than a mirror. This is useful both from a productivity point of view and from a presentation point of view.

Does Miracast Matter?

When Miracast was first released it felt rather revolutionary, but the fact is that Miracast has been overtaken by both AirPlay and Google Cast. Since the mobile device world has been so thoroughly split between iOS and Android, it seems that support for Miracast is a little lackluster. 

If you already happen to own a Miracast device and have a display, there’s nothing wrong in taking advantage of it. However, unless Miracast receives a substantial upgrade, there’s no particular reason to seek this technology out either.
