Description

Method for adaptive switching of EPG page based on lock screen mode

Technical field

The present invention relates to the field of IPTV (Internet Protocol Television) set-top box technology, and in particular, to a method for adaptively switching an EPG page based on a lock screen mode.

Background technique

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. With the higher requirements of the customer base in terms of visual quality and function, SD set-top boxes are gradually being adopted by HD set-top boxes. And the replacement of smart set-top boxes. However, in the high-definition IPTV platform docked with HD 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 HD page (1280*720), but the standard EPG page (640*) is directly transplanted. 530), especially the pages of third-party applications, so that it needs to be a high-definition or smart set-top box of the terminal to adapt to the IPTV platform where the high-definition and standard-definition pages coexist.

High-definition or smart set-top boxes need to have the ability to recognize the original size of a web page, and scale the pages of different sizes to the specified area size. However, browsers with webkit as the kernel are drawn while parsing, which will show the process of page zooming. For example, first display the screen in the upper left corner by a quarter size and then enlarge the full screen display, or first display the page beyond the screen size. Zoom out to full screen display. The appearance of the above phenomenon will affect the user's intuitive visual experience and poor experience. In view of this, the patent proposes a method for adaptive switching of EPG pages based on a lock screen mode.

Summary of the invention

The technical problem to be solved by the present invention is that the page zooming process is presented when the EPG page is zoomed and the user's intuitive visual experience is poor.

In order to solve the above technical problem, the technical solution adopted by the present invention is to provide a method for adaptively switching an EPG page based on a lock screen mode, including the following steps:

Step S1, locking the current screen, and starting to load the target page;

Step S2, starting a page loading progress detection timer T1;

Step S3: When the page loading progress detection timer T1 times out and the page loading state is completed, the actual size of the loaded target page is detected;

Step S4, stretching or reducing the target page whose actual size is different from the specified size to a predetermined size;

In step S5, the lock screen is released, and the content of the target page is displayed.

In the above method, the locking current screen adopts a static frame lock screen manner;

The static frame lock screen displays the currently displayed page as a still frame. The content in the current memory is stored as a still frame, and the next page is no longer read from the buffer for display, thereby achieving the effect of locking the screen.

In the above method, the timeout period of the page loading progress detection timer T1 is set to 500 ms.

In the above method, the actual size of the target page is obtained by the value of page-view-size in the meta tag in the webpage.

In the above method, when the page loading progress detection timer T1 times out and the page loading state is incomplete, the page loading progress detection timer T1 is restarted, and the detection is continued.

In the above method, the present invention further has a forced unlock timer T2 for forcibly releasing the lock screen, and the timeout period is set to 6s.

The invention adopts the page loading progress detection timer T1 timeout and the page loading state is completed. As a basis for judging the completion of loading of the target page, it avoids the influence of the intermediate jump page on the display effect, realizes seamless switching of the EPG page, and determines the page size, webkit parsing, rendering, and page portion when the EPG page size is switched. The refresh process is performed in the lock screen state, does not display to the screen, does not produce visual page zoom exceptions, just like the same size page switch, natural smooth, visual experience. In addition, the present invention is based on the webkit open source browser kernel implementation, and the size conversion of the page issued by the IPTV platform can not only be transplanted to various webkit-based browsers very conveniently and quickly, and has strong capabilities. It is portable, and there is no need to make any modifications to the IPTV platform. IPTV set-top box manufacturers can adapt more quickly when adapting to the network, and the adaptation difficulty is low.

detailed description

The present invention will be described in detail below with reference to the drawings and specific embodiments.

The invention provides a method for adaptively switching EPG pages based on a lock screen mode, and uses webkit as a browser kernel to scale different size EPG pages into uniform size images to achieve adaptive zooming effect, as shown in FIG. , including the following steps:

Step S1, the current screen is locked, and the loading of the target page is started.

In the present invention, the current screen is locked by using a static frame lock screen, that is, the currently displayed page of 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; thus, when receiving the message that the webkit sends the start of the page loading, the content of the target page has not been downloaded to the set top box, the set top box The content of the target page will not be sent to the display buffer, so the content of the previous page exists in the current video memory, and the content in the current video memory is stored as a still frame, and the effect of locking the screen can be achieved.

Among them, the interface of the static frame storage is provided by the chip manufacturer, and the software needs to be modified accordingly for different main chips.

Step S2: Start a page loading progress detection timer T1, wherein the timeout period of the page loading progress detection timer T1 is generally set to 500 ms.

In step S3, when the page loading progress detection timer T1 times out and the page loading state is completed, the actual size of the loaded target page is detected, wherein the actual size of the target page is through the page in the meta tag in the webpage. -view-size value to judge.

Due to the frequent page jump phenomenon in the IPTV platform, there are multiple intermediate pages when loading the target page, and each intermediate page also triggers the loading progress, so the message of the page loading completed by the webkit cannot be simply used as the target. The basis for the completion of the page loading, thereby triggering subsequent actions (detecting the actual size of the loaded target page). The invention overcomes the interference of the intermediate jump page by simultaneously satisfying the page loading progress detection timer T1 timeout and the page loading state completion as the detection basis of the target page loading completion. If the page loading progress detection timer T1 times out and the detected page loading status is incomplete, it indicates that a jump may occur in the page, and the progress at this time includes the progress of the intermediate page, so the page loading progress detection timer T1 is restarted. Continue to test.

In the present invention, a forced unlock timer T2 is also provided, which is used to forcibly release the lock screen, and the timeout period is set to 6s. When the network is abnormal, the page is not fully loaded, and the subsequent operation conditions are not reached, and the long-term operation is avoided. Screen locks affect the user experience.

In step S4, the target page whose actual size is inconsistent with the specified size is stretched or reduced to a predetermined size, and the effect of adaptive scaling is achieved.

It can be seen that the present invention determines that the page size, webkit parsing, rendering, and page partial refreshing process are all performed in a lock screen state, and are not displayed on the screen, thereby improving the user experience.

It is apparent that those skilled in the art can make various modifications and variations to the invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and modifications of the invention
