example 1

[0047] Example 1. The current focus is a non-moving node, and the candidate node is a moving node

[0048] Take moving the focus down as an example. The current focus cur_node is the non-moving focus. Press the button to move to the optional node of the movement. At the moment of moving the arrow keys, get a snapshot of the position of each optional node, and move the moving node move_node to its movement area Projection, calculate the specific position and size of the movement node move_node:

[0049] 1. Reference Figure 3A , when the motion node move_node makes a projection to the motion area, and the projection is completely inside the motion area, the motion node is completely visible, the visible area of ​​the node is its projection range, the focus frame moves from cur_node to move_node, and the position coordinates of the focus frame are move_node coordinates, the size of the focus frame is the size of the projected area of ​​the current motion node;

example 2

[0052] Example 2: The current focus is the motion node, and the candidate nodes are motion nodes

[0053] Take moving the focus to the right as an example. The current focus cur_node is the focus of the movement. Press the button to move to the optional node of the movement. The motion area projection of , calculate the coordinates and size of the projection:

[0054] 1. Reference Figure 4A , cur_node and move_node respectively project to the motion area where they are located. If the projection does not intersect with its motion area, then cur_node and move_node are invisible, and there is no visible candidate node on the right of cur_node, so the focus does not move;

[0055] 2. Reference Figure 4B , the current motion focus cur_node projects to the motion area and partially intersects with the motion area, the current motion focus is partially visible, the position of the focus frame is the position of cur_node, the size of the focus frame is the area where cu...

Abstract

The invention discloses a current focus moving method and a device used for an interactive personal TV terminal. The method comprises the following steps: acquiring currently displayed selectable nodes and the position of the current focus; determining a candidate node in the selectable nodes, wherein, the candidate node is the nearest selectable node to the current focus in the selectable nodes on the current focus moving direction; determining a visible area of the candidate node under the condition that the candidate node is a moving node; and moving the current focus to the visible area ofthe candidate node. By the invention, the network browsing efficiency can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a current focus moving method and device for an Interactive Personal Television (IPTV for short) terminal. Background technique [0002] With the extensive development of IPTV services, more and more dynamic information such as moving pictures and moving subtitles are displayed on web pages. When the IPTV set-top box is operated, when the moving picture and the moving subtitle itself are selectable nodes, the moving selectable nodes and / or the stationary selectable nodes participate in focus movement together, for example: moving from the stationary selectable nodes to the moving selectable nodes Selected nodes, move between moving optional nodes, move from moving optional nodes to stationary optional nodes. [0003] When the focus is moved through the remote control buttons, since the direction, speed, and amplitude of the node's movement can be dynamically set, the position ...
