Abstract
The invention discloses the control method that a kind of Set Top Box figure shows, by respectively browser figure layer, appended drawings layer data and caption data being buffered, then make to hybrid cache of the algorithm BLIT of mixing and mix, then mixing resultant BLIT to frame buffer.The positive effect of the present invention is: using figure layer hybrid technology, the display to Set Top Box figure layer is controlled so that needs each several part content of display can individually show or show simultaneously, and conflicts the most mutually.According to the normal design of figure, if figure layer to show and to hide, it needs to send request, request updates the rectangle that on screen, oneself covers, each figure layer all responds request, the algorithm BLIT of the figure mixing of corresponding rectangle region is done to hybrid cache and mixes, then mixing resultant BLIT to frame buffer, thus solve the webpage of browser middleware access and collision problem that Set Top Box this locality icon shows；Realize Subtitle Demonstration by the mixing of figure layer simultaneously.
Description
Technical field
The present invention relates to set-top box technique field, especially relate to the control method that a kind of Set Top Box figure shows.
Background technology
IPTV i.e. IPTV, is that one utilizes broadband cable net, integrates the multiple technologies such as the Internet, multimedia, communication；Brand-new technology to domestic consumer's offer multiple interactive services including DTV.It can be well adapted for the trend that current network develops rapidly, and substantially effectively utilizes Internet resources.The graphics system of IPTV set top box, in addition to needing to show the platform page that browser Middleware Request shows, also needs to show part UI of player, such as: volume adjusting interface, time shift icon etc.；Additionally, as required local playing function, captions can not need by video layer to show in page layer.In conventional set-top box, simple map overlay mode can not meet requirement on display speed, can cause the problem that display is delayed, page furbishing is slow.
Summary of the invention
In order to overcome the disadvantages mentioned above 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 one, respectively browser figure layer, appended drawings layer data and caption data are buffered:
1) browser figure layer buffering: by browser primary data cache to browser figure layer relief area；
2) appended drawings layer data buffering: appended drawings layer data is cached to appended drawings layer relief area；
3) caption data buffering: caption data is cached to captions figure layer relief area；
Step 2, algorithm BLIT with mixing do to hybrid cache and to mix, then mixing resultant BLIT to frame buffer.
Compared with prior art, the positive effect of the present invention is: using figure layer hybrid technology, the display to Set Top Box figure layer is controlled so that needs each several part content of display can individually show or show simultaneously, and conflicts the most mutually.According to the normal design of figure, if figure layer to show and to hide, it needs to send request, request updates the rectangle that on screen, oneself covers, each figure layer all responds request, the algorithm BLIT(position block transmission of the figure mixing of corresponding rectangle region) do to hybrid cache and to mix, then mixing resultant BLIT to frame buffer, thus solve the webpage of browser middleware access and collision problem that Set Top Box this locality icon shows；Realize Subtitle Demonstration by the mixing of figure layer simultaneously.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is the process of graph layer mixing.
Fig. 2 is the method for the local captions of display.
Detailed description of the invention
The control method that a kind of Set Top Box figure shows, as it is shown in figure 1, comprise the following steps:
Step one, respectively browser figure layer, appended drawings layer data and caption data are buffered:
1) browser figure layer buffering: browser initial data (including: platform webpage, browser middleware figure etc.) is cached to browser figure layer relief area；
2) appended drawings layer data buffering: appended drawings layer data (including: time shift icon layer, network connection icon layer) is cached to appended drawings layer relief area, and concrete grammar is as follows:
When the process relevant to icon sends request, it is desirable to when showing this icon, player updates, to browse request, the rectangle that on screen, this icon covers, and this icon data is cached to appended drawings layer relief area.It is illustrated below:
The shifting state when player is by live entrance, player requests display time shift icon, then send request to browser, browser reads icon data to relief area；And when this icon hidden by needs, browser would not read this icon data to relief area after receiving request.
3) caption data buffering: caption data (local subtitle file) is cached to captions figure layer relief area, and concrete grammar is as follows:
As in figure 2 it is shown, player reads caption data from local subtitle file, and the caption data needing display is saved in local shared drive, and notifies browser.Caption data is cached to captions figure layer relief area by browser.
It should be noted that in step one 1), 2), 3) random combine can be carried out, and there is no sequencing.
Step 2, algorithm BLIT with mixing do to hybrid cache and to mix, and then mixing resultant BLIT to frame buffer, just complete work.Concrete grammar is as follows:
To sightless figure layer, BLIT is not to hybrid cache；To visible figure layer, it is judged that whether the rectangle region of figure layer and renewal rectangle region exist common factor: as occured simultaneously for empty, then BLIT occurs simultaneously；If occured simultaneously for sky, the most not BLIT.Need BLIT if none of appended drawings layer, then skip hybrid cache, direct for browser rs cache BLIT to frame buffer.
The invention enables network graphic and local icon can individually show or show simultaneously, and conflict the most mutually.When page change caption playing frequent, local is more, more show its advantage.
Claims (5)
1. the control method that a Set Top Box figure shows, it is characterised in that: comprise the steps:
Step one, respectively browser figure layer, appended drawings layer data and caption data are buffered:
1) browser figure layer buffering: by browser primary data cache to browser figure layer relief area；
2) appended drawings layer data buffering: appended drawings layer data is cached to appended drawings layer relief area；
3) caption data buffering: caption data is cached to captions figure layer relief area；
Step 2, algorithmic bit block with mixing are transferred to hybrid cache and do and mix, and then mixing resultant position block are transferred to frame buffer:
To sightless figure layer, position block is not transferred to hybrid cache；To visible figure layer, it is judged that whether the rectangle region of figure layer and renewal rectangle region exist common factor: as occured simultaneously for sky, then position block transmission common factor；If occured simultaneously for sky, the most not transmission of position block；Need position block transmission if none of appended drawings layer, then skip hybrid cache, direct for browser rs cache position block is transferred to frame buffer.
