Page multigraph switching realization method and embedded browser of interactive personality TV (IPTV)

Abstract

The invention relates to a page multigraph switching realization method and an embedded browser of an interactive personality TV (IPTV). The method comprises the following steps: capturing a trigger action of a user who selects an element on a page; acquiring a picture address from hidden domain elements corresponding to the page according to a number of the selection element selected by the trigger action; downloading, updating and displaying a picture corresponding to the picture address through the display elements of the page. In the invention, a limited javascript scripting function of the embedded browser of the set top box is used to capture a click action and a selected action of the user. The hidden domain elements are introduced and the picture address is stored in the hidden domain elements. The browser does not need to download the picture actively. The picture is obtained only when the picture is needed so that a request response is fast and a loading page is small. A multigraph switching function can be high efficiently realized. The page is beautiful, dynamic and possesses strong interactivity. User experience can be raised.

Description

technical field [0001] The invention relates to the technical field of IPTV (Interactive Personality TV, Internet TV) page display technology, in particular to a method for implementing page multi-picture switching based on an embedded browser in IPTV and an embedded browser for Internet TV. Background technique [0002] As IPTV enters thousands of households, more people experience the fun brought by broadband, and people's quality of life is thus improved. [0003] At present, audio and video decoding technology, streaming media transmission technology, broadband access network technology and IP set-top box technology in the IPTV system have all developed rapidly. Due to the limitations of the embedded browser used in the display of IPTV terminals, the WEB features supported by the browser are relatively weak, and generally only support limited hypertext slogans (HTML, Hyper Text Markup Language) and very limited functions. Scripting language (javascript). [0004] In ad...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the page has multiple display elements, and the browser needs to download all the pictures, which will cause the page to load too slowly, and the loaded page is too large, which will cause the set-top box to respond slowly to user operations

[0008] 2. Obtaining the picture address asynchronously in the javascript function has the following disadvantages: the number of user requests increases, the pressure on the server is increased, and the browser will also slow down

[0009] Therefore, the existing multi-image switching method cannot realize the multi-image switching effect with fewer requests and smaller pages at the same time
