Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a display processing method and apparatus, and a display system. BACKGROUND OF THE INVENTION Wirelessly, technologies for displaying content of terminals such as smart phones and tablet computers on large-screen displays mainly include Apple's AirPlay technology, Intel's Wireless Display (WIDI) technology, and The standard wireless fidelity (Wi-Fi) Display developed by the Wi-Fi Alliance. Among the many ways, the most promising is Wi-Fi Display technology. Many manufacturers believe that "most of the smart phones and other terminals will come standard with Wi-Fi Display." The so-called Wi-Fi Display function, that is, the mobile phone/mobile PC and the TV/display can be wirelessly connected, allowing the user to enjoy high-quality image display without the need for a connection line. A mobile phone, a personal computer (PC), etc. are regarded as a source device, and a television and a display are regarded as sink devices, and the corresponding Wi-Fi Display is established by the Wi-Fi Alliance. The standard communicates to achieve the effect of synchronous display of the contents of the source device on the sink device. Wi-Fi Display technology only supports one source-to-one sink for one source device, that is, the content of a terminal device such as a smart phone can only be displayed on a large-screen display for display. At present, the receiving device supporting Wi-Fi Display on the market has a mimcast big screen sharer, a small technology PTV, a WiPlug, a multi-smile gold hoop, a millet box, a wireless view, etc., which can be divided into two categories: In the box type, the source device transmits the content to be displayed to the Xiaomi box through the Wi-Fi Display function, and the Xiaomi box outputs the content transmitted by the source device to the display and the television for display through the video interface; Open the mimcast big screen sharer type, insert the device into the display (Universal Serial Bus, referred to as USB) interface, that is, the device communicates with the display through the USB interface, and the Wi device between the source device and the smart open michacast large screen share device Fi Display technology for content delivery. No matter what type of device, only one source-to-one sink can be realized, that is, the content of a terminal device such as a smart phone can only be displayed on a large screen display.
