202, Digital Television (being specially the mobile device of focus in the digital television browser that is integrated in the Digital Television) is obtained all focuses in the current visible page in the digital television browser.

For example, shown in Fig. 7 a, include four objects in the digital television browser in the current visible page, be respectively clock, photograph, perfume and map, wherein, the irregular area that square frame comprises namely is the focus that will process, for convenience, at this clock is called 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 that is integrated in the 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 that is integrated in the Digital Television) is overlapping to some extent according to the rectangular area of determining in the Focal Point Shift instruction determining step 203 that receives in the step 201, if, then execution in step 205, if not, execution in step 206 then.

By Fig. 7 b as can be known, the rectangular area of the rectangular area of focus A and focus B overlaps, and the rectangular area of focus D then comprises the rectangular area of focus C fully, referring to the i.e. diagonal line hatches part among the figure of the overlapping region 1 among the figure and overlapping region 2().If focus A is initial focus, then 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 then focus D is the overlapping focus of focus C, and focus D comprises focus C fully.

For example, take the Focal Point Shift direction of Focal Point Shift instruction indication as " left ", and initial focus is that C is example, and this moment then, Digital Television determines that the rectangular area of the rectangular area of focus C and focus D is overlapping to some extent, therefore, and direct execution in step 205.

205, Digital Television (being specially the mobile device of focus in the digital television browser that is integrated in the Digital Television) is cut apart overlapping rectangular area according to the Focal Point Shift instruction that receives in the step 201, and the rectangular area after will cutting apart is as focus area.

For example, if the Focal Point Shift direction of Focal Point Shift instruction indication be " left ", and initial focus is C, and then at this moment, Digital Television can be obtained first 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 fully, and therefore, Digital Television calculating is updated to " y with the high dy of overlapping region ₁+ h ₁-y ₀" further, if because y ₁＜y ₀, therefore, with the high h of overlapping focus ₁Be revised as " h ₁-dy ".

After the coordinate that process is above-mentioned and the high modification, variation has occured in cutting apart between the rectangular area of the rectangular area of focus C and focus D, and namely 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, namely need not to cut apart.

207, Digital Television according to the Focal Point Shift instruction according to the 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 then 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, then Focal Point Shift arrives after the focus area of focus D, if continue to receive after the Focal Point Shift instruction that is 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.

As seen, the loopy moving mode seems more flexible for the single-way moving mode, is convenient to user's operation, is conducive to improve the user and experiences.

It should be noted that, abovely only describe as " left " as example take the moving direction of Focal Point Shift instruction indication focus, should be understood that, the direction of Focal Point Shift can also be other directions, and its implementation does not similarly 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, behind page open, browser can be given first 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 on the value of the minimum in focus location, namely navigate on the first focus.

As from the foregoing, the present embodiment is after receiving the Focal Point Shift instruction, if determine that the shared rectangular area of focus is overlapping to some extent, then overlapping rectangular area is cut apart, and the rectangular area after will cutting apart is as focus area, in order 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, so that overlapping focus can be chosen to, improved accuracy and the flexibility of Focal Point Shift; And, when carrying out Focal Point Shift, adopted the mode of loopy moving, when having avoided in the prior art single-way moving, need 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 the user and experience.
