Embodiment Construction
[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0046]In order to solve the problem in the prior art that multiple signal sources are connected to the same display device, which leads to confusion in signal source selection and the display device cannot display the signal source that the user wants to display, in the embodiment of the present invention, the user pre-sets Set a priority configuration information for each interface, and then connect signal sources with high demand to interfaces...

The present invention discloses a display device signal source selection method and device used for solving the problem in the prior art that a plurality of signal sources are accessed in a same display device, so that the signal source selection is disordered, and the display device can not display the signal sources that users hope to display. The method comprises the steps of using the display device to traverse each interface connected with a signal source at present, after all interfaces in which the input signals exist are screened, according to the preset priority configuration information, determining the current priority of each interface in which the input signal exists separately, and selecting the signal source connected with the interface of which the priority is highest at present to display. Therefore, the situation that when the input signals exist in the plurality of interfaces, the display device also can display the signal source that the users hope to display is guaranteed, and also the problem that the display device can not display normally without the input signals is avoided.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a method and device for selecting a signal source of a display device. Background technique [0002] With the continuous development of science and technology, video output devices such as set-top boxes, game consoles, and DVD players are becoming more and more popular. Most families will have multiple video output devices, but generally there is only one display device. The video output devices are all connected to one display device for display. In the prior art, after multiple video output devices are connected to the same display device, the display device selects the video output device that the user wishes to select (hereinafter referred to as the video output device). When the output device is the signal source) for display, there are usually two methods of manual selection and automatic selection, specifically: [0003] The method of manually selecting the signa...
