Embodiment Construction

[0053] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0054] In order to facilitate the understanding of the application, here is a brief description of the embodiment of the application:

[0055] The terminal equipment in the screen projection system includes the transmitting end and the receiving end. The data to be delivered (that is, the data that needs to be projected) can be divided into two types: media data and non-media data. ...

Abstract

The invention provides a screen projection method and device and a delivery end, which are suitable for the technical field of screen projection, and the method comprises the following steps: if a screen projection function is started, the delivery end determines to-be-delivered data; if the to-be-delivered data is media data, the delivery end obtains a first data permission of the delivery end to the to-be-delivered data and a second data permission of the receiving end to the to-be-delivered data; and if the first data permission is higher than the second data permission, the delivery end delivers the to-be-delivered data to the receiving end in a screen mirroring manner. And if the first data permission is lower than the second data permission, the delivery end delivers the to-be-delivered data to the receiving end in a digital life network alliance mode. According to the embodiment of the invention, the method can achieve the automatic selection of the screen projection mode, and always provides a higher data authority for the to-be-delivered data for a user, and achieves the playing of the media data. Therefore, a better screen projection effect can be achieved in the actual screen projection process, and the user experience is improved.

Description

technical field [0001] The present application belongs to the technical field of screen projection, and in particular relates to a screen projection method, device and delivery terminal. Background technique [0002] With the advancement of technology, the number of terminal devices owned by users is increasing day by day. Screen projection and sharing between terminal devices has become a daily demand of users. [0003] The terminal equipment in the screen projection system includes the transmitting end and the receiving end. Common screen projection methods include screen mirroring (Miracast) and Digital Live Network Alliance (Digital Live Network Alliance, DLNA). Wherein, the screen mirroring means that the transmitting end mirrors the contents of the entire screen of itself to the corresponding receiving end. And DLNA is a projection solution. Based on a set of interconnection protocols among computers, mobile terminals and consumer appliances, DLNA allows the sendin...
