Embodiment Construction

[0028] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0029] see figure 1 , in this embodiment, a Miracast-based image projection method includes the following steps:

[0030]Step S101: the Miracast sending end sends screen parameters and image data to the Miracast receiving end, the screen parameters include: screen orientation and screen resolution. In this embodiment, before the image is projected, the Miracast sending end starts the Miracast function, and the Miracast sending end scans the surrounding Miracast receiving ends, connects to a specified Miracast receiving end, and determines whether the connection is successful. If the connection is not successful, repeat the connection operation, If the connection is successful, send the image data and the screen parameters to the Mira...

Abstract

The invention relates to the technical field of multimedia protection, and in particular relates to an image projection method and an image projection system based on Miracast. The image projection method based on Miracast comprises the steps as follows: a Miracast sending end sends screen parameters and image data to a Miracast receiving end, wherein the screen parameter comprises a screen direction and a screen resolution; the Miracast receiving end judges whether both the screen direction of the Miracast sending end and the screen direction of the Miracast receiving end are vertical, and if yes, the Miracast receiving end cuts out an effective area of the image data, and amplifies and moves the effective area of the image data according to the screen direction of the Miracast sending end and the screen direction of the Miracast receiving end. According to the method and the system provided by the invention, the problem that the screen direction of the Miracast sending end is vertical, so that the vertical image data cannot be projected to the vertical Miracast receiving end and displayed in a full screen manner, and thus people cannot normally watch the projection screen on the Miracast receiving end, and a projection effect requirement cannot be met is solved.

Description

technical field [0001] The invention relates to the technical field of multimedia projection, in particular to a Miracast-based image projection method and system. Background technique [0002] With the development of projection technology, mirroring technology is becoming more and more popular. Mirroring technology is a technical solution launched by the Digital Living Network Alliance or a confusion of virtual network computing technology. At present, technologies related to mirroring technology mainly include AirPlay Mirroring of Apple, WiDi of Intel, AWD3.0 of AMD, WiGig of WiGig Alliance, UltraGig (Wireless HD), and Wireless Digital Home Interface of WHDI Alliance (WHDI), MirrorLink from the Auto Connect Alliance, and Miracast. [0003] Among them, Miracast is currently one of the most promising technologies, through Wi-Fi CERTIFIED Wi-FiDirect TM To form a connection, you don't need to be connected to any Wi-Fi network. In the Miracast specification, devices are div...
