Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
The technical means described in the embodiments of the present invention may be arbitrarily combined without conflict.
In addition, in the embodiments of the present invention, "first", "second", and the like are used for distinguishing similar objects, and are not necessarily used for describing a specific order or a sequential order.
Currently, there are two main screen projection technologies in the related art. The first screen projection technology is a push mode, and the push mode is mainly used for projecting screen video and music, for example, after screen projection is realized between a mobile phone and a television, the mobile phone can be turned off or other applications can be run, and the television cannot stop playing, so that the mobile phone can be played and the television can be watched without errors. The principle of the push mode is that the mobile phone and the television are connected with the same WiFi (Wireless-Fidelity), a special channel similar to Bluetooth is established through a screen-casting protocol, after the mobile phone searches the television, the mobile phone sends a video address to the television, the television starts to play the video after receiving the address, and the mobile phone can also control the playing progress of the television. The second screen projection technology is a mirror image mode, which is mainly used for functions of a screen projection mobile phone ppt (powerpoint), a mobile phone desktop, games and the like. For example, the screen mirroring of an apple phone and the multi-screen interaction of an android phone all belong to mirroring functions. The mobile phone and the television are connected with the same WiFi in the mode, after the mobile phone and the television are connected in a mirror image mode, the mobile phone can continuously send a screenshot to the television, and the television is displayed after receiving the screenshot, so that the television and the mobile phone can be displayed on the same screen.
The screen projection technology requires that the mobile phone and the television are connected with the same wireless network regardless of a push mode or a mirror mode. If a plurality of mobile phones and a plurality of televisions are connected with the same wireless network, one mobile phone can project contents to any one television. In this case, a television being projected is likely to be preempted by the screen projection of other mobile phones, so that the screen projection is interrupted, and the user experience is affected. In order to solve the problem, the related art provides a scheme of code scanning connection and screen projection codes, screen projection software is installed on a mobile phone end and a television simultaneously, and screen projection codes on the television are input or scanned on the mobile phone, so that accurate screen projection in a one-to-one mode can be achieved. Although the technology can achieve accurate screen projection in a one-to-one mode, screen projection software is required to be installed on a mobile phone end and a television end, and some screen projection software needs to be registered and logged in, so that operation is inconvenient and cost is increased. For example, in a hotel, the hotel needs to install screen projection software for each television in a guest room, the guest needs to install the screen projection software by himself after the guest enters the hotel, and then the two-dimensional code is scanned to use the screen projection function, so that the operation cost of the hotel is increased, and great inconvenience is brought to the guest.
