Description
Technical field
The present invention relates to application set top box multi-screen scroll techniques field, more particularly to a kind of set top box multi-screen to roll word
Method and system.
Background technology
At present, as the development of DTV, top box of digital machine are expanded with popularizing in each corner in the world.With work(
Energy constantly improve, DTV STB, which has, rolls the function that word is shown.So multi-screen roll system meet the tendency of and
It is raw.
At present, set top box on the market realizes that effect is not fine to character rolling.The rolling effect that conventional text rolls
It is more single, the phenomenon for having interim card is rolled to multi-screen.
The content of the invention
One of the technical problem to be solved in the present invention, it is to provide a kind of method that set top box multi-screen rolls word, can be with
There are a variety of roll modes, can control rolling speed, and display multi-screen that can be efficiently errorless rolls.
What one of problem of the present invention was realized in：A kind of method that set top box multi-screen rolls word, methods described include
Following steps：
Step 1, multiple single screens are together in series to form a multi-screen with chain sheet form；The single screen is by the first virtual screen, and
Two virtual screens, wait screen, and wing flats is formed；First virtual screen is to enter left margin to screen rightmost circle from the first frame
In the range of display place；Second virtual screen is that word is rolled out to completely without word letter after screen is shown completely from right margin
Virtual display curtain in the range of breath；It is described to wait the data that screen is storage word next frame；Wing flats is used for directly filling
Character background；
Step 2, when user need show and roll passage when, a structured data, the structure need to be filled
Data include word content, font prospect background, screen display location, screen display size, display speed and display effect；
Step 3, the structured data for obtaining word, corresponding dot array data is found out from set top box character library and in word
Individual character data are combined in order, and lteral data is recombinated by display effect；And the first virtual screen or the second virtual screen for passing through single screen
It has been shown that, when word length exceed single screen the first virtual screen and the second virtual screen width when, the first virtual screen and second
Virtual screen is shown together；Next frame character display data is obtained by display speed again, deposit is waited in screen；The data handled well
Insertion is shown in queue；
Step 4, single screen is passed sequentially through to showing that the data in queue are shown.
Further, the step 4 is specially：Receive and show data in queue, show the content of the first frame, the after display
One single screen can be changed into wait state, carry out next single screen and show, continue to fill up after next frame data again by first single screen
It is set to dispaly state, during single screen in this multi-screen of poll, can judges whether to take turns herein to other single screens successively according to processing speed
Carry out data and show that other single screen states are dispaly state, are, then continue to show, otherwise next round continues to judge again, Zhi Daoman
The single screen of dispaly state continues to show after sufficient condition.
Further, the wing flats can be filled rear projection screen or be not filled with according to customer demand.
The second technical problem to be solved by the present invention, it is to provide the system that a kind of set top box multi-screen rolls word, can be with
There are a variety of roll modes, can control rolling speed, and display multi-screen that can be efficiently errorless rolls.
What the two of problem of the present invention were realized in：The system that a kind of set top box multi-screen rolls word, the system include
Multi-screen sets up module, data reception module, data processing module and data disaply moudle；
The multi-screen sets up module, for multiple single screens to be together in series to form a multi-screen with chain sheet form；The single screen
By the first virtual screen, the second virtual screen waits screen, and wing flats is formed；First virtual screen is to enter left margin from the first frame
Display place in the range of to screen rightmost circle；Second virtual screen is that word rolls out after screen is shown completely from right margin
To completely without the virtual display curtain in the range of text information；It is described to wait the data that screen is storage word next frame；The back of the body
Scape screen is used for directly filling character background；
The data reception module, for when user needs to show and rolls passage, a structure need to be filled
Data, the structured data include word content, font prospect background, screen display location, screen display size, display speed
Degree and display effect；
Data processing module, for obtaining the structured data of word, corresponding dot matrix number is found out from set top box character library
According to simultaneously individual character data in word are combined in order, lteral data is recombinated by display effect；And the first virtual screen for passing through single screen
Or second virtual screen shown, when word length exceed single screen the first virtual screen and the second virtual screen width when, first
Virtual screen and the second virtual screen are shown together；Next frame character display data is obtained by display speed again, deposit is waited in screen；
The data insertion handled well is shown in queue；
Data disaply moudle, the data in display queue are shown for passing sequentially through single screen.
Further, the data processing module is specially：Receive and show data in queue, show the content of the first frame,
First single screen can be changed into wait state after display, carry out next single screen and show, continue to fill up after next frame data again by
One single screen is set to dispaly state, during single screen in this multi-screen of poll, can judge whether to take turns herein to other according to processing speed
Single screen carries out data and shown successively, and other single screen states are dispaly state, are, then continue to show, otherwise next round continues to sentence again
Disconnected, the single screen of dispaly state continues to show after meeting condition.
Further, the wing flats can be filled rear projection screen or be not filled with according to customer demand.
The invention has the advantages that：Multi-screen of the present invention is connected by single screen with chain sheet form, convenient to increase and decrease screen.First He
Second virtual screen can completely handle the indication range needed for rolling, without only carrying out complicated algorithm meter by a screen
Calculate, directly shown, accelerate display speed, improve display efficiency.Wing flats can also directly fill display, text
Word need to only handle foreground.Wait screen to be handled when former frame is shown, after the completion of display, wait screen meeting
Data are copied into the first and second virtual screens, save the time.(traditional method is one frame of display, then waits next frame processing,
Show again, have a strong impact on efficiency).Data disaply moudle is poll waiting mechanism, more reasonably goes to show word using timeslice
Data.
