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

Disclosed in the present invention is a lock screen mode-based EPG page adaptive switching method, comprising: locking a current screen, and starting to download a target page; starting a page loading progress detection timer T1; when the page loading progress detection timer T1 times out and a page loading status reads complete, detecting the actual size of the loaded target page; when the actual size of the target page does not match a specified size, stretching or reducing the actual size to the specified size; unlocking the screen to display the target page content. The present invention achieves seamless switching of the EPG page and does not produce visual abnormalities in page scaling during EPG page size switching, resulting in a natural, smooth and pleasant visual experience; in addition, since the present invention is a webkit-based open source browser kernel implementation and used for switching sizes for pages sent under an IPTV platform, the invention enjoys strong transferablity, and low adaptation difficulty.

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...
