Abstract
Methods for realizing advanced graphical user interface (GUI) in panel subunit. The present invention defines, in one embodiment, a focus in user action and a focus out user action for panel subunit. The focus in/out user actions, when received by a controller device, are then passed to the target device. When the target device receives the focus in/out user actions, the target device will be able to update the GUI appropriately. The present invention also provides a user action pass-through element for conditionally passing through user actions to the target device. In one embodiment, when a scroll button that is implemented with the user action pass-through element is in focus, focus navigation commands received by the controller are passed through to the target device. By using the focus in/out user actions and by using the conditional user action pass-through mechanisms of the present invention, more complicated and advanced GUI, such as an electronic programming guide (EPG) can be achieved.
