Thanks to built-in Wi-Fi Direct protocol, Miracast not need to connect any other wireless network to transmit data. Miracast has many advantages compared to the traditional method of wireless content such as WiDi, or DLNA, AirPlay.
If closely monitored tech news lately, you will hear the term Miracast. Understanding briefly, is a communications protocol that allows wireless content you stream content from one device to another device. Miracast organized by WiFi Alliance (WiFi Alliance) is considered to be developing and answers WiFi Alliance coalition for AirPlay Mirroring and Wi-Di - communication protocols like wireless content from Apple and Intel. So Miracast is and what it is worth noting, let's find out. Miracast What is That said, Miracast is a communications protocol wireless content organization named by the WiFi Alliance (WiFi Alliance) to formed. Miracast allows us to transfer content from one device to another device, such as connecting to Samsung's smartphone users on an external monitor by Sony, share a laptop on a projector screen in real time ... The strength of Miracast Wireless Communications content is not a new concept. Previously, the device has a lot of traditional methods such as DLNA content. This type of solution allows you to watch content stored in file 1 1 devices on the external display. However, DLNA is limited in the scope of multimedia files like movies, video or image. DLNA also tend to make it difficult to set up and requires the device to have wireless connectivity, require passwords or require specialized applications to connect. they can also connect devices is the external monitor using wired connections like HDMI or Mobile High Definition Link (MHL). The advantage of this connection, you can connect the entire contents of the screen on the device, not limited as DLNA. However, as we have seen, this is required to connect wires, not convenient for users. Miracast solution seems to be DLNA and HDMI combines above. It is a wireless solution helps to stream from one screen mobile device to an external monitor, but do not like HDMI cables. You also do not need to have one wireless network for 2 separate devices can connect to. Miracast is built on Wi-Fi Direct protocol to transfer data (Wi-Fi Direct is a standard that allows WiFi devices to connect to each other without a wireless access point - a device that allows the device wireless connection to a wired network via WiFi, Bluetooth or similar standards). Miracast do not need to set the password, the connection takes place very quickly. In particular, you only need 1 smartphone (or tablet) and 1 Miracast certified TVs have this certification, you can connect your smartphone to your TV, do not need any network or internet device other supports. A demo video Miracast connections. As mentioned, Miracast connections can only perform on the devices it supports certified. However, if you want to stream music or videos from a device that supports Miracast to 1 device is not supported, you can use an adapter (adapter) Miracast and connect this adapter to your USB port or HDMI device was not supported. At that time, two devices will recognize each other according to this standard. devices support number? At the present time, the number of supported devices is not much Miracast. However, in the near future, the number of supported devices Miracast will quickly increase. Samsung Miracast previously integrated into the Galaxy S III. In the future, the Korean company will take it up the line Echo-P Series HDTV. Google has also taken over Miracast on Android 4.2 OS with new products like LG Nexus Nexus and Nexus 10. Not only that, in the future we will see a lot of products labeled compatible Miracast appeared on the market as Sony, LG and many other companies have teamed together to support this standard. LG said Miracast will be integrated into their TV next year. Compared with WiDi and AirPlay To see the benefits of Miracast great, let's compare it with two rivals as WiDi and AirPlay. WiDi and AirPlay protocol as well as the wireless content like Miracast, but others just as they are developed by separate companies. More specifically, WiDi and AirPlay is a proprietary product of Intel (WiDi) and Apple (AirPlay). Only Apple devices can shader (broadcast) signals AirPlay and Apple TV only recently received waves. WiDi laptop is limited on the use of Intel Core chips. Also, you have to buy extra adapter cost $ 100 to use the WiDi chip manufacturers. The technology is also the only "wireless" part and not entirely certain as Miracast, by both WiDi and AirPlay to need an external box connected to the TV via HDMI cable. Taken together, Miracast see very ideal. But whether it succeeds or not the technology itself and this has limited what we will discuss in the next post. Refer: Cnet, Digitaltrend, Wikipedia
