Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] A method for self-adaptive switching of EPG pages based on a lock screen mode provided by the present invention uses webkit as the browser kernel to realize the scaling of EPG pages of different sizes into images of a uniform size to achieve the effect of self-adaptive scaling, such as figure 1 shown, including the following steps:

[0021] Step S1, lock the current screen, and start loading the target page.

[0022] In the present invention, locking the current screen adopts the method of still frame lock screen, that is, the page currently displayed by the set-top box is displayed as a still frame, and the content in the current video memory is stored as a still frame, and the next page is no longer read from the buffer. Display; in this way, when receiving the page loading start message sent by webkit, the content of the target pag...

Abstract

The invention discloses an EPG page self-adaptive switching method based on a screen locking mode. The method comprises the steps of: locking a current screen, and starting to load a target page; starting a page loading schedule detection timer T1; when the page loading schedule detection timer T1 is overtime and the page loading state is completed, detecting the practical size of the loaded target page; stretching or shortening the size of target page whose practical size is different from a prescribed size into the prescribed size; and removing the screen locking, and display the content of the target page. According to the invention, EPG page seamless switching is realized, and in the EPG page size switching process, no visual page zooming abnormality is generated, the process is natural and smooth, and the visual experience is good; in addition, the method is realized based on an open source browser inner core of webkit, and size conversion is carried out for the pages issued by an IPTV platform, so that the transportability is relatively high, and the adaptation difficulty is low.

Description

technical field [0001] The invention relates to the technical field of IPTV (Internet Protocol Television, IP TV / interactive network TV) set-top box, in particular to a method for adaptive switching of EPG pages based on a lock screen mode. Background technique [0002] In recent years, with the integration of the three networks, IPTV set-top boxes have become more and more widely used under the promotion of major operators, and as the customer base puts forward higher requirements in terms of visual quality and functional perfection, SD set-top boxes are gradually being replaced by HD set-top boxes And replaced by smart set-top boxes. However, at present, in the high-definition IPTV platform docked with high-definition and smart set-top boxes, in order to save the development cost of the EPG platform, the EPG page is not completely switched to the high-definition page (1280*720), but the standard-definition EPG page (640*720) before it is directly transplanted. 530), espec...
