Six kinds of wireless projection screen comparison, see you pink which one
Wireless projection is a mode of interaction between multiple screens in the past year or two. It is commonly used for multi-screen interaction of mobile phones, tablets, computers, projectors, all-in-one PCS and other screens. The original business screen projection field has developed rapidly to all walks of life. Now there are more and more electronic products supporting screen projection devices. However, as we all know, Apple uses Airplay screen image while Android phones use multi-screen interaction.
Let’s first analyze from the wireless screen projection technology, the current wireless screen projection technology mainly has six branches:
①AirPlay screen image: A wireless playback technology launched by Apple, suitable for iOS and Mac systems wireless screen projection.
Advantages: Built-in functions of Apple series devices, with the use of screen projector supporting AirPlayserver service, the effect is clear and stable, the protocol comes with screen code function;
Disadvantages: Ensure that the Apple device and the screen projector are in the same LAN (same network segment) and cannot be used across network segments or vlans. An enterprise with a responsible network architecture can be cumbersome to use.
②Miracast Multi-Screen Interaction: A wireless display standard formulated by the Wi-Fi Alliance and based on Wi-FiDirect. 3C devices that support this standard can share video images wirelessly.
Advantages: Miracast protocol built in Android5.0 and above phones allows for multi-screen interaction without installing any software. Without any network support, direct wireless screen projection can be performed through the WiFiP2P function between the screen projection device and the WiFi network card of the receiving device. Supports synchronous transmission of audio and video.
Disadvantages: Android devices are too numerous and complex, and Miracast is not fully compatible with all Android devices. The screen projection does not have the screen projection code function to prevent malicious or incorrect screen projection.
③WiDi technology: The WIDI technology is dominated by Intel, and the two technologies, WiDi and Miracast, are two sets of protocols with the same origin, interconnectivity, and are fully compatible (both based on WiFiDirect technology).
Advantages: Windows8/10 laptop native support WiDi, no need to install any software directly screen; Support USB reverse control function;
Disadvantages: WindowsXP/7 is not supported, and there are some compatibility issues.
④DLNA push: DLNA service is push, which can push the multimedia on the mobile phone to the big screen (TV or projector) in the form of URL for playback.
Advantages: Support for streaming media push
Disadvantages: No mirror projection. DLNA is mainly used for watching TV movies in the home market and is not suitable for enterprise applications.
⑤APP projection software: By installing a client in the transmitter (mobile phone or computer), the screen image is pushed to the big screen (TV or projector) for playback.
Advantages: Can be customized, integrated, can provide SDK for enterprise secondary development. At present, some major technology companies have developed iOS, Android, Mac, Windows full system client. It can integrate the functions of two-dimensional code scanning and screen projection code. Without complicated operation, you can quickly cast the screen by scanning or inputting the screen projection code.
Cons: AndroidAPP only supports video, not audio; They are basically private protocols developed independently by each manufacturer and cannot be used interchangeably.
⑥ Wireless screen projection device: in fact, it is a derivative of APP software screen projection. The receiving end is regarded as a hardware box, and the signal end has two ways of USB small electronic devices and APP software. Bijie Internet focus on wireless screen projection for 16 years, wireless screen projection, we are professional!
Advantages: Through external hardware, ensure audio and video transmission quality, screen projection process is more convenient, with hardware as the carrier, a variety of functions can be built in;
Cons: Need to purchase hardware, relatively high cost.
It can be seen from the comparison of six wireless screen projection modes that each mode has its own advantages. In daily life applications, we can choose the appropriate mode according to our own conditions, which can greatly improve our screen projection experience.
