If the control is music, a poster of a music album can be displayed. If the control is an application, it may be displayed as an icon for the application or a screenshot of the content captured for the application when it was most recently executed. If the control is the user access history, the control can be displayed as a content screenshot in the latest execution process.
In some embodiments, the control may represent an interface or a set of interfaces to which the display device 200 is connected to an external device, or may represent a name of an external device connected to the display device, or the like. Such as: a signal source input interface set, or an HDMI interface, a USB interface, a PC terminal interface, etc.
The presentation forms of the controls are generally diversified. For example, the controls may include textual content and/or images for displaying thumbnails related to the textual content, or video clips related to the text. As another example, the control can be text and/or an icon of the application.
It should also be noted that the selector is used to indicate that any one of the controls has been selected, such as the focus object. In one aspect, the control may be selected or controlled by controlling the movement of the focus object displayed in the display apparatus 200 according to an input of the user through the control apparatus 100. Such as: the user may select and control the controls by controlling the movement of the focus object between the controls through the directional keys on the control device 100. On the other hand, the movement of each control displayed in the display apparatus 200 may be controlled according to the input of the user through the control device 100 to cause the focus object to select or control the control. Such as: the user can control the controls to move left and right together through the direction key on the control device 100, so that the focal object can be selected and controlled when the position of the focal object is kept unchanged.
The form of identification of the selector is often diversified. For example, the position of the focus object is realized or identified by enlarging the control, the position of the focus object is realized or identified by setting the background color of the control, and the position of the focus object can also be identified by changing the border line, size, color, transparency, outline and/or font of the text or image of the focus control.
