Mirror display system and mirror display method

This creation department is related to the display system and the display method, and particularly relates to the mirror display system and the mirror display method.

With the rapid development of science and technology, various mobile devices have been proposed. By using mobile devices, people can easily access services anytime, anywhere, such as browsing the web, editing papers, watching movies, or instant messaging.

However, due to convenience and power consumption considerations, mobile devices are often only equipped with small-sized display screens. When the user uses the aforementioned service via the mobile device, since the display screen of the display screen is too small, the user cannot view all the details of the display screen. Moreover, watching the small-sized display screen for a long time will cause the user's vision to decline.

In order to solve the above problems, a mirror display system has been proposed. Please refer to FIG. 1. FIG. 1 is a schematic diagram of the use of a conventional mirror display system. As shown in FIG. 1, the conventional mirror display system 1 includes a mobile device 10 and a display device 14.

The mobile device 10 can simultaneously execute a plurality of contents (such as the plurality of applications 100-106), and display an execution screen 1000 of one of the plurality of contents (here, the application 100 is taken as an example) on the mobile device 10 The screen 12 is touched and the other plurality of applications 102-106 are executed in the background.

Next, how the conventional mirror display system 1 provides the user's mirror display service will be described. After the mobile device 10 is connected to the display device 14, the mobile device 10 can continue to transmit the execution screen 1000 of the application 100 to the display device 14. Next, the display device 14 displays the received execution screen 1000 on a display screen 16. Thereby, the user can directly view the execution screen 1000 of the application 100 of the mobile device 10 in the display screen 16 having a large size.

However, the conventional mirror display system 1 can only mirror the current display of the mobile device 10 The execution screen 1000 is shown, and cannot be simultaneously displayed on the execution screen of the other plurality of applications 102-106 executed in the background. In other words, the conventional mirror display system 1 cannot assist the user to simultaneously use the services provided by two or more applications (such as simultaneously watching movies and performing instant messaging).

Therefore, the conventional mirror display system has the above problems, and a more effective solution is proposed.

Specifically, the rendering module 2040 visualizes the screen of the read/execute/decode result of the content 2020 to render the view corresponding to the content 2020. And in some cases, the view is directly used as the display material corresponding to the content 2020 (described later in detail).

Further, when the processing component 204 determines that the rendering module 2040 does not support drawing the view corresponding to the content 2020 (if the transmitting device 20 does not support reading/execution/decoding the content 2020), the processing module 204 can be connected via the plugin. Or the third party program converts the content 2020 into a display image as the display material corresponding to the content 2020. When it is determined that the drawing module 2040 supports the content 2020 (if the transmitting device 20 supports reading/executing/decoding the content 2020), the view of the execution screen corresponding to the content 2020 is drawn via the rendering module 2040. .

In another embodiment of the present invention, the transmitting device 20 further includes a display component 208 electrically connected to the processing component 204. When the processing component 204 determines that the display component 208 has displayed the view, the processing component 204 directly captures the current display image of the display component 208 as the display material corresponding to the content 2020. Specifically, the content 2020 corresponding to the displayed view is the content that is executed by the sending device 20 on the top layer. The content 2020 corresponding to the view that is not displayed is the sending The content that the end device 20 executes in the background.

By drawing the view corresponding to the content 2020 by the drawing module 2040, the present invention can be effectively obtained even if the content 2020 is executed in the background (ie, the execution screen of the content 2020 is not displayed on the display element 208). This execution screen of the content 2020.

In another embodiment of the present invention, the processing component 204 further includes a format determining module 2042 that determines whether the receiving device 30 supports the data format of the content 2020. The processing component 204 does not display the view on the display component 208, and the format determining module 2042 determines that the receiving device 30 supports the data format of the content 2020, and directly uses the content 2020 as the display material. The processing component 204 does not display the view on the display component 208, and the format determining module 2042 determines that the receiving device 30 does not support the data format of the content 2020, and uses the view as the corresponding content of the content 2020. data.

For example, if the content format of the content 2020 is an image file of the Joint Photographic Experts Group (JPEG), and the receiving device 30 can support reading the image file of the JPEG. The format determining module 2042 can determine that the receiving device 30 supports the data format of the content 2020. In this case, the processing component 204 can directly use the content 2020 as the display material and transmit it to the receiving device 30 without transmitting the view corresponding to the content 2020.

In another embodiment of the present invention, the processing component 204 further includes an adjustment module 2044 for adjusting a current display range or a display ratio of the plurality of display materials.
