Embodiment Construction

[0149] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0150] The present invention aims at the problem that the screen transmission technology between WIFI-based multi-terminals in the prior art can only realize one-to-one projection, and provides a display processing method and device. The target area corresponding to each other does not conflict with each other to generate the target image and display it on a display module, which solves the problem that the screen transmission technology between multiple terminals based on WIFI can only realize one-to-one projection, making multiple terminals The data can be projected onto a display device to achieve the effect of split-screen display.

[0151] In the embodiment of the present invention, the receiving end supports receiving data sent by multiple sending ...

Abstract

Provided are a display processing method and device, the display processing method for a sink comprising: obtaining a source image separately transmitted by at least two current sources connected to a sink in a WIFI direct connection manner; generating a target image comprising each source image according to target regions without mutual collision and separately selected by each source; the target region corresponding to the source is used for indicating position information of the source image corresponding to the source in the target image; and outputting the target image to a display module so as to display the target image comprising each source image on the display module. An embodiment of the present invention generates the target image according to the source image transmitted by at least two sources, and the target region without mutual collision and corresponding to the source, and displays on the display module, thus addressing the problem of only achieving one-to-one projection in a screen transmission technique between multiple terminals based on the WIFI, such that data of the multiple terminals can be projected on a display device to achieve split-screen display.

Description

technical field [0001] The invention relates to the technical field of multimedia communication, in particular to a display processing method and device. Background technique [0002] In the prior art, the protocol architecture of wireless multimedia screen sharing technology is basically clear; Wi-Fi Display is a standard formulated by Wi-Fi Alliance, and version 1.0 was released in September 2012. Miracast is the Wi-Fi Alliance's certification program for Wi-Fi Display technology implementation products. Normally used without distinguishing between Wi-Fi Display and Miracast. [0003] Wi-Fi Display technology is based on MAC layer point-to-point (Wi-Fi Direct) transmission to realize wireless transmission of audio and video data, which is similar to the mirror display function in Apple Air Play. The Andriod 4.2 platform released by Google in October 2012 began to support the Miracast function. [0004] Compared with Apple's Air Play function, Wi-Fi Display's function is...
