Embodiment approach

[0068] Step S310: Obtain the screen data of the projection terminal, and perform color format conversion on the screen data;

[0069] Step S320: Obtain the screen aspect ratio of the mobile terminal, and update the coding ratio according to the screen aspect ratio;

[0070] Step S330: Encoding the color format conversion result according to the encoding ratio to obtain projection data;

[0071] Step S340: sending the screen projection data to a mobile terminal so that the mobile terminal displays the screen projection data;

[0072] and figure 2 The corresponding embodiments are different. In step S310 of the embodiment of the present application, before the screen projection terminal encodes the screen data, the screen size of the mobile terminal is obtained in advance, and the coded value is updated according to the screen size of the mobile terminal. Proportion. The initial value of the coding ratio may be a preset value that is suitable for the aspect ratio of the scre...

Abstract

The embodiment of the invention provides a screen projection method and device. In a displaying process of screen projection data, a first screen triggering event sent from a mobile terminal is received, and the type of the first screen triggering event is obtained; according to the type of the first screen triggering event, a response is given to the first screen triggering event; and the updated screen projection data obtained after the response is sent to the mobile terminal. A purpose that the mobile terminal displays and controls the data of a screen projection terminal is realized.

Description

technical field [0001] Embodiments of the present invention relate to the field of video technology, and in particular, to a screen projection method and device. Background technique [0002] Multi-screen interaction is a technology that is quietly emerging nowadays. Multi-screen interaction refers to the use of IGRS protocol, Miracast protocol, etc., through WIFI network connection, on different multimedia terminals (such as common operating systems based on Ios, Android, Symbian, etc.) Different intelligent terminal devices on the system, such as mobile phones, PADs, TVs, etc.) perform a series of operations such as transmission, analysis, display, and control of multimedia (audio, video, and picture) content, and users can share them on different platform devices at the same time Display content to enrich users' multimedia life. As far as the implementation technology is concerned, multi-screen interaction means that the screens of several devices can be connected and co...
