Example Embodiment

[0054] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0055] For clarity of expression, first define and explain the movement direction of the present invention: In view of the fact that when browsing the page, the user scrolls the page more along the Y axis in the two-dimensional coordinate, the focus movement method and device of the present invention only use the Y axis direction The focus movement of is taken as an example for description. The focus movement method in the X-axis direction is the same as the focus movement method in the Y-axis direction, and will not be repeated here.

Abstract

The invention provides a method for moving focuses based on an embedded browser. The method comprises the following steps of: A, generating a plurality of real focus chain tables according to the height of a page to be browsed and the height of a screen of the browser; B, extracting nodes for supporting real focuses from a typesetting tree of the page to be browsed; adding the nodes to the plurality of real focus chain tables; C, determining target real focus chain tables according to the real focus chain tables which the nodes of the current real focuses belong to and movement directions; and D, according to the distances from the nodes for supporting the real focuses included in the target real focus chain tables to the nodes of the current real focuses, determining nodes of the target real focuses; and switching the focuses from the nodes of the current real focuses to the nodes of the target real focuses. The invention further provides a device for moving focuses based on an embedded browser. By adopting the method and device disclosed by the invention, the focus movement speed can be increased; the time consumption is reduced; and the focus movement fluency is improved.

Description

technical field [0001] The present invention relates to an interactive network television (Internet Protocol Television, IPTV) technology and a digital television technology, in particular to a focus moving method and device based on an embedded browser. Background technique [0002] With the progress of society and the continuous improvement of users' pursuit of high-quality life, browser technology has entered the field of embedded systems. Whether it is digital TV, IPTV, or even mobile phone platforms, it is inseparable from the support of embedded browsers. [0003] Embedded systems have some inherent characteristics: (1) The central processing unit (Central Processing Unit, CPU) has weak capabilities and low power consumption, and the capabilities of these processors are far inferior to the CPUs of personal computers (Personal Computer, PC); (2) ) The memory resources are very limited, plus the space occupied by its own browser and some other auxiliary functions, leavin...
