摘要： The method and apparatus determine a specific position of a user-selectable region at a particular point in time within a sequence of display frames. The method and apparatus first interpolate between a first matrix representing the user-selectable region at a first point in time and a second matrix representing the user-selectable region at a second point in time. In one embodiment, the matrix generated by this interpolation is then applied to a region definition for the user-selectable region to determine the specific area occupied by the region at the particular point in time. According to one embodiment, the first matrix and the second matrix are both stored within the same sample of a container track. This sample corresponds to one or more frames of the sequence of display frames. In an alternate embodiment, the first matrix and the second matrix are stored in two separate samples of the container track.

摘要： A method for managing focus in a graphical user interface using a directional controller that allows a directional or selection input. The method comprising: determining whether the input is directional or selection; determining whether there is a sibling object of a currently focused object in a given direction of the input if the input is directional; transferring the focus to the sibling object if there is a sibling object in the given direction; transferring the focus to an ancestor object of the currently focused object if there is no sibling object in the given direction; determining whether the currently focused object is a group; transferring the focus to a descendant object of the currently focused object if the currently focused object is a group and the input is selection; and selecting the currently focused object if the currently focused object is not a group and the input is selection.
