Focus element display method, device and digital television receiving terminal

Abstract

The invention provides a focus element display method, a device and a digital television receiving terminal. The method comprises the following steps: creating two overlapped web page windows; loading web page contents selected by users on the lower-layer window; loading a transparent web page on the upper-layer window; obtaining the typeset information of the lower-layer window; determining the position of a current focus element; carrying out special effect drawing in the corresponding position of the upper-layer window according to the position of the current focus element; and displaying the web page after the special effect drawing is completed. The focus element display method, the device and the digital television receiving terminal provided by the invention have the advantages that when users browse the web page, the terminal does not need to interact with the front end terminal, the analytic speed is accelerated, and the animation effect of the focus switching can be realized. At the same time, the focus abnormity problem of the network environment differential time can be solved, and the downloading load of the front end equipment is reduced.

Description

technical field [0001] The present invention relates to the technical field of digital television, in particular to a focus element display method, device and digital television receiving terminal. Background technique [0002] With the continuous development of digital TV technology, digital TV receiving terminals have more and more functions, and surfing the Internet through an embedded browser has become one of the main functions. The embedded browser is different from the browser on the computer. On the computer, when the user is more interested in a certain link, he only needs to click the link with the mouse to browse the relevant link content. However, the embedded browser on the digital television receiving terminal does not have a mouse, but only a remote controller. So the embedded browser must highlight the current focus (that is, where the currently selectable link is located), telling the user where the current focus is. Users can use the up, down, left, and r...

Problems solved by technology

However, this effect needs to replace the picture. Issues such as the source of the picture and the size of the focus element have caused limitations in the selection of pictures.

At the same time, during the switching process of the focus element, it is necessary to download the replacement picture from the front-end device, which affects the switching speed, causes the network to be abnormal, and may also cause errors in the switching of the focus element, or the problem of jumping focus switching

[0006] To sum up, by replacing the picture to display the focus element, because the data needs to be downloaded from the front-end device, it will affect the switching speed and increase the load of the front-end device

Realizing the animation effect of web pages through JavaScript scripting language will inevitably increase a lot of JavaScript script codes, which will affect the overall performance of the browser

At the same time, it also increases the amount of code written by web page developers (also affects the load of front-end equipment)
