Abstract

The invention discloses a method for controlling set-top box image display. The method comprises steps of buffering a browser image layer, additional image layer data and caption data, conducting mixing on mixing buffering through a mixing algorithm BLIT, and buffering mixing result BLIT frames. The method has the advantages that a layer mixing technology is used, the display of a set-top box is controlled, and all part content to be displayed can be displayed separately or at the same time and don't conflict. According to the normal design mode of an image, if the image layer is displayed or covered, the request is sent, the covering rectangle on the screen is requested to be updated, all image layers response the request, the image in the corresponding rectangular region is mixed in the mixing buffering through the mixing algorithm BLIT, the mixing result BLIT frames are buffered, the problems that a web page which is accessed by a middle member of a browser conflicts with the set-top box local icon display is solved and the caption display is achieved through the image layer mixing.

Description

The control method that the set-top box figure shows

Technical field

The present invention relates to the set-top box technique field, especially relate to the control method that a kind of set-top box figure shows.

Background technology

IPTV is IPTV, is a kind of broadband cabled television network that utilizes, and integrates the multiple technologies such as the Internet, multimedia, communication; The brand-new technology of the multiple interactive services that comprises Digital Television is provided to the domestic consumer.The trend that it can adapt to current network develop rapidly well fully effectively utilizes Internet resources.The graphics system of IPTV set-top box is except the platform page that needs the request of display navigation device middleware and show, and the part UI of the device that also need display the play is such as volume adjusting interface, time shift icon etc.; In addition, as essential local playing function, captions can not need to show in page layer by video layer.Simple map overlay mode can not meet the demands on display speed on the conventional set-top box, can cause to show hysteresis, the slow problem of page furbishing.

Summary of the invention

In order to overcome the above-mentioned shortcoming of prior art, the invention provides the control method that a kind of set-top box figure shows.

The technical solution adopted for the present invention to solve the technical problems is: the control method that a kind of set-top box figure shows comprises the steps:

Step 1, respectively browser figure layer, appended drawings layer data and caption data are cushioned:

1) browser figure layer buffering: with the browser primary data cache to browser figure layer buffering area;

2) appended drawings layer data buffering: the appended drawings layer data is cached to appended drawings layer buffering area;

3) caption data buffering: caption data is cached to captions figure layer buffering area;

Step 2, do mixing with the algorithm BLIT that mixes to hybrid cache, then mixing resultant BLIT is arrived frame buffer.

Compared with prior art, good effect of the present invention is: an employing figure layer hybrid technology, the demonstration of set-top box figure layer is controlled, so that need the each several part content of demonstration to show separately or simultaneously demonstration, and not mutually conflict.According to the normal design of figure, if the figure layer will show and hide, it need to send request, the rectangle that oneself covers on the screen is upgraded in request, each figure layer is response request all, the figure of corresponding rectangle region is transmitted with the algorithm BLIT(position piece that mixes) do mixing to hybrid cache, then mixing resultant BLIT is arrived frame buffer, thereby solve the webpage of browser middleware access and the collision problem of the local icon demonstration of set-top box; Mix by the figure layer simultaneously and realize Subtitle Demonstration.

Description of drawings

Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:

Fig. 1 is the process that graph layer mixes.

Fig. 2 is for showing the method for local captions.

Embodiment

The control method that a kind of set-top box figure shows as shown in Figure 1, may further comprise the steps:

1) browser figure layer buffering: browser initial data (comprising: platform webpage, browser middleware figure etc.) is cached to browser figure layer buffering area;

2) appended drawings layer data buffering: appended drawings layer data (comprising: time shift icon layer, network connection icon layer) is cached to appended drawings layer buffering area, and concrete grammar is as follows:

When the process relevant with icon sent request, when requiring to show this icon, player upgrades the rectangle that this icon covers on the screen to browse request, and this icon data is cached to appended drawings layer buffering area.Illustrate as follows:

When player shifting state during by live entering, player requests shows the time shift icon, then sends request to browser, and browser reads icon data to buffering area; And when needs are hidden this icon, just can not read this icon data to buffering area after the browser request of receiving.

3) caption data buffering: caption data (local subtitle file) is cached to captions figure layer buffering area, and concrete grammar is as follows:

As shown in Figure 2, player reads caption data from local subtitle file, and the caption data that will need to show is saved in local shared drive, and the notice browser.Browser is cached to captions figure layer buffering area with caption data.

Need to prove 1 in the step 1), 2), 3) can carry out random combine, and do not have sequencing.

Step 2, do mixing with the algorithm BLIT that mixes to hybrid cache, then mixing resultant BLIT is arrived frame buffer, just finished work.Concrete grammar is as follows:

To sightless figure layer, BLIT is not to hybrid cache; To visible figure layer, judge the rectangle region of figure layer and upgrade rectangle region whether have common factor: as occuring simultaneously not for empty, then BLIT occurs simultaneously; If occur simultaneously for empty, BLIT not then.If neither one appended drawings layer needs BLIT, then skip hybrid cache, the direct BLIT of browser rs cache is arrived frame buffer.

The invention enables network graphic and local icon to show separately or simultaneously demonstration, and not mutually conflict.When frequent, the local caption playing of page variation is more, more show its advantage.

Claims

1. the control method that the set-top box figure shows is characterized in that: comprise the steps:

2. the control method that shows of set-top box figure according to claim 1, it is characterized in that: described browser initial data comprises platform webpage, browser middleware figure.
