Terminal screen content synchronous display control device and method

Abstract

The invention discloses a control device and method for displaying a content of a terminal screen synchronously. The control device for displaying the content of the terminal screen synchronously comprises an image collection module, a cache module and an interface control module, wherein the image collection module collects screen output data of a first terminal according to a screen output clock of the first terminal and writes the collected data into the cache module; and an image transmission control module reads the data from the cache module and sends the data to a second terminal through a universal interface. According to the technical scheme, the synchronous display of the content of the terminal screen is realized in a hardware manner, so that the display velocity and the display quality of a picture can be guaranteed; and at the same time, software is not required to be installed on a terminal at present, the occupation of resources is reduced, and the problem of compatibility of the software and an operation system is not required to be considered as well.

Description

technical field [0001] The invention relates to the technical field of terminal testing, in particular to a terminal screen content synchronous display control device and method. Background technique [0002] During the testing process of mobile terminals such as mobile phones and tablet computers, due to the limited functions of the mobile terminal itself, in some cases, it is necessary to synchronously display the content displayed on the terminal screen to a PC or other test terminals to Get more testing done. [0003] According to the prior art, the main schemes that can realize the synchronous display of terminal screen content include VNC and LCD2VGA. In the process of realizing the present invention, the inventor finds that at least the following problems exist in the prior art: [0004] For LCD2VGA: firstly, after the signal is converted into VGA, it needs to be collected on the PC side, the hardware cost is relatively high, and the secondary development of the PC s...

AI Technical Summary

Problems solved by technology

Compared with LCD2VGA, VNC uses software, and the implementation cost is relatively low, but the synchronous image display speed of this method is slow, and the average frame rate is only 5 or 6 frames, which is difficult to meet the test requirements; in addition, VNC needs to be installed on the terminal side Running the control software, on the one hand, consumes resources such as CPU and memory on the terminal, affecting the test effect. On the other hand, whether the software can be installed depends on whether the operating system on the terminal supports it, which also affects the universality of the test solution. sex
