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". 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.
Wireless HDMI is the wireless transmission of high-definition audio and video signals between devices, using unlicensed radio frequencies like 5 GHz, 60 GHz, or 190 GHz. This technology eliminates the need for an HDMI cable , allowing users to transmit signals wirelessly between the component device and the display device.
CEC [3] is a separate electrical signal from the other HDMI signals. This allows a device to disable its high-speed HDMI circuitry in sleep mode, but be woken up by CEC. It is a single shared bus, which is directly connected between all HDMI ports on a device, so it can flow through a device which is completely powered off (not just asleep).
A further complication is that there is a small amount of display equipment, such as some high-end home theater projectors, designed with HDMI inputs but not HDCP-compliant. Any DVI-to-HDMI adapter can function as an HDMI-to-DVI adapter (and vice versa). [54]
WHDI 1.0 provides a high-quality, uncompressed wireless link which supports data rates of up to 3 Gbit/s (allowing 1920×1080 @ 60 Hz @ 24-bit) in a 40 MHz channel, and data rates of up to 1.5 Gbit/s (allowing 1280×720 @ 60 Hz @ 24-bit or 1920×1080 @ 30 Hz @ 24-bit) in a single 20 MHz channel of the 5 GHz unlicensed band, conforming to FCC and worldwide 5 GHz spectrum regulations.
The WirelessHD specification is based on a 7 GHz channel in the 60 GHz Extremely High Frequency radio band. It allows either lightly compressed (proprietary wireless link-aware codec) or uncompressed digital transmission of high-definition video and audio and data signals, essentially making it equivalent of a wireless HDMI.
Centrino was a brand name of Intel Corporation which represented its Wi-Fi and WiMAX wireless computer networking adapters. The brand name was first used by the company as a platform-marketing initiative. The change of the meaning of the brand name occurred on January 7, 2010. [1]: 1 The Centrino name for laptops was replaced by the Ultrabook.
Wireless Zero Configuration (WZC), also known as Wireless Auto Configuration, or WLAN AutoConfig, is a wireless connection management utility included with Microsoft Windows XP and later operating systems as a service that dynamically selects a wireless network to connect to based on a user's preferences and various default settings.
