![]() ![]() (ex: Apple MacBooks, even with compatible Intel Core processors and Wi-Fi support that would be able to do Miracast if they were using Windows, either natively or under BootCamp, are not supported.) A software, firmware or OS update doesn't grant Miracast on uncertified hardware, even if the minimum requirements are met. ![]() ![]() Also, as a certified hardware standard, Miracast device support is 100% OEM determined. Even with certification, it is possible an underpowered device will be constrained in performance or bandwidth. the time between the display of pictures on the source and display of the mirrored image on the sync display). LPCM mode 16 bits, 44.1 kHz sampling, 2 channelsĬertification does not mandate a maximum latency (i.e.Mandated audio codec: Linear Pulse-Code Modulation (LPCM) 16 bits, 48 kHz sampling, 2 channels Optional: ITU-T H.265 ( High Efficiency Video Coding ) for HD and Ultra HD video supports several profiles in transcoding and non-transcoding modes, including Main Profile, Main 444, SCC-8 bit 444, Main 444 10, at levels ranging from 3.1 to 5.1 Mandatory: ITU-T H.264 ( Advanced Video Coding ) for HD and Ultra HD video supports several profiles in transcoding and non-transcoding modes, including Constrained Baseline Profile (CBP), at levels ranging from 3.1 to 5.2 12 handheld formats, from 640 x 360 up to 960 x 540 pixels, and from 30 to 60 fps.34 Video Electronics Standards Association (VESA) formats, from 800 x 600 up to 2560 x 1600 pixels, and from 30 to 60 fps.27 Consumer Electronics Association (CEA) formats, from 640 x 480 up to 4096 x 2160 pixels, and from 24 to 60 frames per second (fps). ![]() This is accomplished by using a Wi-Fi version of the same trusted content mechanisms used on cable-based HDMI and DisplayPort connections. Miracast can stream videos that are in 1080p, media with DRM such as DVDs, as well as protected premium content streaming, enabling devices to stream feature films and other copy-protected materials. However, to stream music and movies to a non-certified device, Miracast adapters are available that plug into HDMI or USB ports. The Wi-Fi Alliance suggested that Miracast could also be used by a set-top box wanting to stream content to a TV or tablet.īoth devices (the sender and the receiver) need to be Miracast certified for the technology to work. Miracast is "effectively a wireless HDMI cable, copying everything from one screen to another using the H.264 codec and its own digital rights management (DRM) layer emulating the HDMI system". In particular, it obviates having to worry about format or codec details. Miracast devices negotiate settings for each connection, which simplifies the process for the users. The technology was promoted to work across devices, regardless of brand. Miracast hardware now supports HD, FHD and 4K screen streaming. Version history VersionĬorrected heading errors in sections 4.3 and 4.4. On the application layer, the stream is initiated and controlled via RTSP, RTP for the data transfer. On the transport layer, TCP or UDP are used. The connection is created via WPS and therefore is secured with WPA2. It allows sending up to 1080p HD video ( H.264 codec) and 5.1 surround sound ( AAC and AC3 are optional codecs, mandated codec is linear pulse-code modulation – 16 bits 48 kHz 2 channels). Miracast is based on the peer-to-peer Wi-Fi Direct standard. The Wi-Fi Alliance maintains a list of certified device models, which numbered over 6,700 as of 9 March 2017. In 2017, Wi-Fi Alliance stated Miracast as a use for Wi-Fi Direct. Nvidia announced support in 2012 for their Tegra 3 platform, and Freescale Semiconductor, Texas Instruments, Qualcomm, Marvell Technology Group and other chip vendors have also announced their plans to support the Miracast standard. Devices that are Miracast-certified can communicate with each other, regardless of manufacturer. The Wi-Fi Alliance launched the Miracast certification program at the end of 2012. The protocol is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View and AllShare Cast (by Samsung), SmartShare (by LG), screen mirroring (by Sony), Cast (in Windows 11), wireless display and screen casting. It can roughly be described as " HDMI over Wi-Fi", replacing cables in favor of wireless. Miracast is a wireless communications standard created by the Wi-Fi Alliance which is designed to transmit video and sound directly from devices (such as laptops, tablets, or smartphones) to display receivers (such as TVs, monitors, or projectors).
