Embodiment Construction
[0029] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0030] An embodiment of the present invention provides a data sharing method for desktop layout, the method includes: analyzing data information that is not related to screen pixels in the image transmitted from the first device, and the size of the image is determined by the area it occupies on the first screen The first screen is the screen of the first device, and the second screen is the screen of the second device. The data information that has nothing to do with screen pixels includes the aspect ratio aspectRatio of the first screen, the The ratio xRatio of the abscissa of the top ...

The invention provides a data sharing method and apparatus for a desktop layout in multi-screen sharing, and aims to solve the technical problems of difficulty in parameter matching and shared interface distortion easily caused by existing multi-screen sharing. The method comprises the steps of analyzing data information unrelated to screen pixels in an image transmitted from a first device; according to the longitudinal size, the transverse size and the aspect ratio of a second screen, generating a largest rectangular region with the size not exceeding the size of the second screen on the second screen; moving the largest rectangular region to enable the geometric center of the largest rectangular region to coincide with that of the second screen; and according to xMax, yMax, wMax, hMax, xRatio, yRatio, wRatio and hRatio, calculating x2, y2, w2 and h2. According to the method provided by the invention, equivalently the difference among the screens is isolated, so that when multimedia data such as the image and the like is transmitted from one screen to the other screen, parameters still can be matched with those of the other screen, the remote modification of the desktop layout in multi-screen sharing can be realized as needed, and the distortion of the desktop layout in multi-screen sharing is not caused.
Description
technical field [0001] The invention belongs to the field of wireless control of intelligent equipment, and in particular relates to a data sharing method and device for desktop layout under multi-screen sharing. Background technique [0002] Multi-screen interaction refers to the digital living network alliance (Digital Living Network Alliance, DLNA) agreement, IGRS agreement or Miracast agreement, etc., through WiFi network connection, on different multimedia terminals, for example, based on IOS, Android or Symbian, etc. A series of operations such as transmission, analysis, display and control of multimedia (including audio, video and pictures, etc.) content can be performed between different smart terminal devices (such as mobile phones, PDAs and TVs) on the operating system Share display content on platform devices at the same time. Simply put, multi-screen sharing means that the screens of several devices are connected and converted through special connection devices....
