Embodiment bis-,
According to the described method of embodiment mono-, below will be described in further detail for example.
In the present embodiment, by take the mobile device of focus in this digital television browser, specifically can be integrated in Digital Television as example describes.
As shown in Figure 6, idiographic flow can be as follows:
201, Digital Television (being specially the mobile device of focus in the digital television browser being integrated in Digital Television) receives Focal Point Shift instruction.
Wherein, the moving direction of Focal Point Shift instruction indication focus, such as, upwards, downwards, to the left or to the right, etc.
For convenience, in embodiments of the present invention, by take the moving direction of this Focal Point Shift instruction indication focus, as " left " as example, describe.This Focal Point Shift instruction can be triggered by the button in remote controller or Digital Television by user, and concrete triggering mode can, referring to prior art, not repeat them here.
202, Digital Television (being specially the mobile device of focus in the digital television browser being integrated in Digital Television) is obtained all focuses in current visible page in digital television browser.
For example, as shown in Figure 7a, in digital television browser, in current visible page, include four objects, be respectively clock, photograph, perfume and map, wherein, the irregular area that square frame comprises is by focus to be processed, for convenience, at this, clock is called to focus A, photograph is called focus B, perfume is called focus C, and map is called focus D.
203, Digital Television (being specially the mobile device of focus in the digital television browser being integrated in Digital Television) is determined the rectangular area that each focus is shared;
For example, specifically can be referring to Fig. 7 b, wherein, the shared rectangular area of focus A can be referred to as the rectangular area of focus A, the shared rectangular area of focus B can be referred to as the rectangular area of focus B, the shared rectangular area of focus D can be referred to as the rectangular area of focus D, and the shared rectangular area of focus C can be referred to as the rectangular area of focus C.
204, whether Digital Television (being specially the mobile device of focus in the digital television browser being integrated in Digital Television) is overlapping to some extent according to rectangular area definite in the Focal Point Shift instruction determining step 203 receiving in step 201, if, perform step 205, if not, perform step 206.
From Fig. 7 b, the rectangular area of the rectangular area of focus A and focus B partly overlaps, and the rectangular area of focus D comprises the rectangular area of focus C completely, referring to the i.e. diagonal line hatches part in figure of the overlapping region 1 in figure and overlapping region 2().If focus A is initial focus, focus B can be called the overlapping focus of focus A, and still, focus B also not exclusively comprises focus A; In like manner, if focus C is initial focus, can claim that focus D is the overlapping focus of focus C, and focus D comprises focus C completely.
For example, the Focal Point Shift direction of the Focal Point Shift instruction of take indication is " left ", and initial focus is that C is example, now, Digital Television determine the rectangular area of focus C and the rectangular area of focus D overlapping to some extent, therefore, directly perform step 205.
205, Digital Television (being specially the mobile device of focus in the digital television browser being integrated in Digital Television) is cut apart overlapping rectangular area according to the Focal Point Shift instruction receiving in step 201, and the rectangular area after cutting apart is as focus area.
For example, if the Focal Point Shift direction of Focal Point Shift instruction indication is " left ", and initial focus is C, and now, Digital Television can first be obtained the coordinate (x of initial focus (being focus C) 0, y 0), the coordinate (x of overlapping focus (being focus D) 1, y 1), the wide w of the shared rectangular area (being the rectangular area of focus C) of initial focus 0with high h 0, and the wide w of the shared rectangular area (being the rectangular area of focus D) of overlapping focus 1with high h 1, and calculate wide dx and the high dy of overlapping region (being overlapping region 2).
Because the Focal Point Shift direction of Focal Point Shift instruction indication be " left ", and focus D comprises focus C completely, and therefore, Digital Television calculating is updated to " y by the high dy of overlapping region 1+ h 1-y 0" further, if due to y 1<y 0, therefore, by the high h of overlapping focus 1be revised as " h 1-dy ".
After the coordinate that process is above-mentioned and high modification, there is variation in cutting apart between the rectangular area of focus C and the rectangular area of focus D, and amended parameters is:
The coordinate of focus C is (x 0, y 0), the height of focus C is h 0, the wide of focus C is w 0;
The coordinate of focus D is (x 1, y 1), the height of focus C is " h 1-dy ", the wide of focus C is w 1;
The wide of overlapping region is dx, and high dy is " y 1+ h 1-y 0".
For example, specifically can be referring to Fig. 7 c, this figure is the focus area of each focus after cutting apart: the focus area of the focus area of focus A, the focus area of focus B, focus C and the focus area of focus D.
206, Digital Television will not have overlapping rectangular area directly as focus area, without cutting apart.
207, Digital Television according to Focal Point Shift instruction according to focus area moving focal point.
For example, if the Focal Point Shift direction of Focal Point Shift instruction indication is " left ", and initial focus is focus C, and Digital Television can move to focus the focus area of focus D from the focus area of focus C.
It should be noted that, the movement of focus can be unidirectional, also can circulate, such as, if Focal Point Shift is unidirectional, because the left side of the focus area of focus D does not have other focus area, so can not continue to be moved to the left; And if Focal Point Shift circulates, after Focal Point Shift arrives the focus area of focus D, if after continuing to receive the Focal Point Shift instruction being moved to the left of user's triggering, focus will move to from the focus area of focus D the focus area of focus A, by that analogy, do not repeat them here.
Visible, loopy moving mode, for single-way moving mode, seems more flexible, is convenient to user's operation, is conducive to improve user and experiences.
It should be noted that, above moving direction of only take Focal Point Shift instruction indication focus describes as " left " as example, should be understood that, the direction of Focal Point Shift can also be other directions, and its implementation similarly, does not repeat them here.
In addition, also it should be noted that, when the initial opening page, will relate to the location of first focus, in order to realize quick location, can make index of reference locate first focus; For example, after page open, browser can first be given focal point settings focus index value, general, minimum value is on the upper left side of the page, subsequently, system simulation sends a Tab button to browser, like this, browser will, automatically in the minimum value in focus location, navigate in first focus.
As from the foregoing, the present embodiment is after receiving Focal Point Shift instruction, if determine that the shared rectangular area of focus is overlapping to some extent, overlapping rectangular area is cut apart, and the rectangular area after cutting apart is as focus area, to carry out the movement of focus, thereby can avoid the generation of the situation that overlapping focus is skipped when carrying out Focal Point Shift, overlapping focus can be chosen to, improve accuracy and the flexibility of Focal Point Shift; And, when carrying out Focal Point Shift, adopted the mode of loopy moving, while having avoided in prior art single-way moving, the situation that repeatedly movement could be from last Focal Point Shift to first focus, the flexibility that has greatly improved Focal Point Shift, user-friendly, be conducive to improve user and experience.
