Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Basic thought of the present invention is: the optional node of at first determining current focus, obtain the position and size of current focus and optional node then, according to the position of current focus and optional node and the distance of definite current focus of size and optional node, and the shortest optional node of judging distance, by above-mentioned steps, focus can be moved to the shortest optional node of distance of current focus.
As shown in Figure 1, IPTV terminal focus mobility method of the present invention (is example to move down) may further comprise the steps:
Step 101: after terminal received the focus move, the optional node of current focus was determined in move according to focus.
Described focus move is generally sent by button up and down by the user, expression needs focus up to descend left and right directions to move respectively, the optional node that determine this moment is, optional node is positioned at the moving direction side of current focus, and on moving direction with the non-overlapping node of current focus.
As shown in Figure 2, the shape of optional node and current focus is generally quadrangle, if optional node or current focus shape are not quadrangle, for easy calculating, also gets the shape of its circumscribed quadrilateral as optional node and current focus.The quadrangle of optional node has four angle points, is the shortest angle point of optional node distance from the nearest angle point of current focus in these four angle points.
For example the focus move of Jie Shouing is for moving down focus, be that moving direction is downward, position according to current focus among Fig. 2, node 1 is positioned at the top of current focus, there are coincidence in node 2 and node 3 in the projection of current focus on downward direction, be not optional node, and node 4, node 5, node 6, node 7 are optional node.
Step 102: obtain the position and size of current focus and optional node, determine the distance of current focus and optional node according to the position and the size of current focus and optional node.
The position of current focus and optional node can be determined by its central point, also can be determined by its upper left angle point.In the present embodiment, select the position of optional node to be determined by its central point, after the central point of current focus and optional node and size were determined, its four corner location had separately also just been determined to get off.Obtain internet page that described focus or optional node central point and size show from the IPTV terminal or the content of multimedia, for example can indicate the particular location of each link or button in the source code of internet page.
Distance between calculating optional node and the current focus is the distance between computer center's point directly, consider the size of node factor, select following mode in the present embodiment: when on the orthogonal direction at moving direction lap being arranged, determine that current focus and optional node are the distance of optional node and current focus along the distance on the moving direction when optional node and current focus; Otherwise, determine that the air line distance between the shortest angle point of distance of current focus and optional node is the distance of optional node and current focus.
Wherein, described orthogonal direction is and the moving direction direction of quadrature mutually.Shown in Fig. 3 (a), current focus and optional node 8 exist overlapping at the orthogonal direction of moving direction, thus the distance between current focus and the optional node 8 be between the two along the distance on the moving direction, be the size of four-headed arrow among the figure.Shown in Fig. 3 (b), current focus and optional node 9 do not exist overlapping on the orthogonal direction of moving direction, so the air line distance of the shortest angle point of distance is distance between current focus and the optional node 9 between current focus and the optional node 9.
Step 103: the shortest optional node of distance of determining current focus.
The shortest optional node of distance of determining current focus has dual mode:
First kind of mode, if optional node and current focus are unequal apart from each, then the shortest optional node of distance is the shortest optional node of distance, if there is an above optional node to equate with the current focus distance, then determines the shortest optional node of distance according to the shortest mode of visual effect distance.
Wherein, the shortest mode of described visual effect distance is: when a plurality of optional nodes equated with the current focus distance, selecting had overlapping optional node to be the shortest optional node of distance on the orthogonal direction of moving direction with current focus; If there are several on the orthogonal direction of moving direction, to have overlapping optional node to equate with the current focus distance, be chosen in then that overlapping maximum optional node is the shortest optional node of distance on the orthogonal direction of moving direction, if not having has overlapping optional node on the orthogonal direction of moving direction, serve as the shortest optional node of distance then with first optional node on the orthogonal direction of moving direction.
Shown in Fig. 4 (a), optional node 10 and optional node 11 equate with distance between the current focus, and it is overlapping that optional node 11 and current focus have on the orthogonal direction of moving direction, so select optional node 11 as apart from the shortest optional node.
Shown in Fig. 4 (b), optional node 12 and optional node 13 equate with distance between the current focus, optional node 12 and optional node 13 and current focus all have overlapping on the orthogonal direction of moving direction, are the shortest optional node of distance so select to overlap maximum optional node 13 with current focus on the orthogonal direction of moving direction.
Shown in Fig. 4 (c), optional node 14 and optional node 15 equate with distance between the current focus, optional node 14 and optional node 15 all do not have overlapping on the orthogonal direction of moving direction with current focus, so according to visual custom, the optional node 14 of selecting the left side is as the shortest optional node of distance.
The second way, in order to meet user's visual custom more, the distance of the judging current focus operation of short optional node comprises, if on the orthogonal direction of moving direction, arrive the maximum distance and the minimum distance of current focus with current focus zero lap optional node, all less than with current focus the distance of overlapping optional node to current focus being arranged on the orthogonal direction of moving direction, determine that then the zero lap optional node is the shortest optional node of the two middle distance, otherwise determine that with current focus overlapping optional node being arranged is the shortest optional node of the two middle distance.Wherein, described maximum distance is an optional node from the distance of current focus distance angle point farthest to current focus, and minimum distance is an optional node from the distance of the nearest angle point of current focus to current focus.
Shown in Fig. 5 (a), optional node 16 does not have lap with current focus on the orthogonal direction of moving direction, and optional node 17 has lap with current focus on the orthogonal direction of moving direction, because maximum distance between optional node 16 and the current focus and minimum distance are all less than the distance between optional node 17 and the current focus, so in optional node 16 and optional node 17, determine optional node 16 as the shortest optional node of distance, represent maximum distance and the minimum distance of optional node 16 with two band arrow solid lines that point to optional node 16 respectively among Fig. 5 (a) to current focus.
Shown in Fig. 5 (b), optional node 18 and optional node 20 do not have lap with current focus on the orthogonal direction of moving direction, optional node 19 has lap with current focus on the orthogonal direction of moving direction, minimum distance between optional node 18 and the current focus is less than the distance between optional node 19 and the current focus, and the maximum distance between the current focus is greater than the distance between optional node 19 and the current focus, distance between optional node 20 and the current focus is greater than the distance between optional node 19 and the current focus, so at optional node 18, between 19 and 20, determine that optional node 19 is as nearest optional node.Represent maximum distance and the minimum distance of optional node 18 with two band arrow solid lines that point to optional node 18 respectively among Fig. 5 (b) to current focus.
Step 104: moving focal point is to nearest optional node place.
The above is preferred embodiment of the present invention only, is not to be used for limiting protection scope of the present invention.Those skilled in that art should be able to associate; determine the position and the size of optional node and current focus by different way; determine the distance between optional node and the current focus by different way; and determine nearest optional node according to different modes, and other is equal to accordingly to change or replace according to technical scheme of the present invention and design thereof and all should belongs to protection scope of the present invention.
