Description
Technical field
The present invention relates to application Set Top Box multi-screen scroll techniques field, particularly relate to a kind of method and system of Set Top Box multi-screen rolling word.
Background technology
At present, along with the development of Digital Television, top box of digital machine is promoted in each corner in the world with universal.Along with function is constantly perfect, digital TV set-top box has the function that rolling word carries out showing.So multi-screen rolling system is arisen at the historic moment.
At present, Set Top Box on the market realizes effect to character rolling is not fine.The rolling effect that conventional text rolls is more single, to the phenomenon that multi-screen rolling has card to pause.
Summary of the invention
One of the technical problem to be solved in the present invention, is a kind of method providing Set Top Box multi-screen rolling word, can has multiple roll mode, can control rolling speed, and display multi-screen that can be efficiently errorless rolls.
One of problem of the present invention is achieved in that a kind of method of Set Top Box multi-screen rolling word, and described method comprises the steps:
Step 1, multiple single screen to be together in series formation one multi-screen with chain sheet form; Described single screen is by the first virtual screen, and the second virtual screen, waits for screen, and wing flats is formed; Described first virtual screen enters left margin to the display place in the scope of screen rightmost circle from the first frame; Second virtual screen is that word rolls out the virtual display curtain do not had completely in the scope of Word message after screen shows completely from right margin; Described wait screen is the data depositing word next frame; Wing flats is used for directly filling character background;
Step 2, when user need display and rolling passage time, need fill a structured data, described structured data comprises word content, font prospect background, screen display location, screen display size, display speed and display effect;
The structured data of step 3, acquisition word, finds out corresponding dot array data and individual character data in word is combined in order from Set Top Box character library, by display effect restructuring lteral data; And shown by the first virtual screen of single screen or the second virtual screen, when word length exceedes the width of the first virtual screen of single screen and the second virtual screen, the first virtual screen shows together with the second virtual screen; Press display speed again and obtain next frame character display data, stored in wait screen; The data handled well are inserted in display queue;
Step 4, successively by single screen to display queue in data show.
Further, described step 4 is specially: receive data in display queue, show the content of the first frame, show rear first single screen and can become wait state, carry out next single screen display, again first single screen is set to show state after continuing to fill next frame data, during single screen in this multi-screen of poll, can judge whether to take turns at this to carry out data display successively to other single screens according to processing speed, other single screen states are show state, are, then continue display, otherwise next round continues to judge again, until the single screen of show state continues display after satisfying condition.
Further, described wing flats can carry out filling rear projection screen according to customer demand or not fill.
The technical problem to be solved in the present invention two, is the system providing a kind of Set Top Box multi-screen rolling word, can has multiple roll mode, can control rolling speed, and display multi-screen that can be efficiently errorless rolls.
Two of problem of the present invention is achieved in that a kind of system of Set Top Box multi-screen rolling word, and described system comprises multi-screen and sets up module, data reception module, data processing module and data disaply moudle;
Described multi-screen sets up module, for multiple single screen being together in series formation one multi-screen with chain sheet form; Described single screen is by the first virtual screen, and the second virtual screen, waits for screen, and wing flats is formed; Described first virtual screen enters left margin to the display place in the scope of screen rightmost circle from the first frame; Second virtual screen is that word rolls out the virtual display curtain do not had completely in the scope of Word message after screen shows completely from right margin; Described wait screen is the data depositing word next frame; Wing flats is used for directly filling character background;
Described data reception module, for need as user display and rolling passage time, need fill a structured data, described structured data comprises word content, font prospect background, screen display location, screen display size, display speed and display effect;
Data processing module, for obtaining the structured data of word, finding out corresponding dot array data and individual character data in word is combined in order from Set Top Box character library, by display effect restructuring lteral data; And shown by the first virtual screen of single screen or the second virtual screen, when word length exceedes the width of the first virtual screen of single screen and the second virtual screen, the first virtual screen shows together with the second virtual screen; Press display speed again and obtain next frame character display data, stored in wait screen; The data handled well are inserted in display queue;
Data disaply moudle, for showing the data in display queue by single screen successively.
Further, described data processing module is specially: receive data in display queue, show the content of the first frame, show rear first single screen and can become wait state, carry out next single screen display, again first single screen is set to show state after continuing to fill next frame data, during single screen in this multi-screen of poll, can judge whether to take turns at this to carry out data display successively to other single screens according to processing speed, other single screen states are show state, be, then continue display, otherwise next round continues to judge again, until the single screen of show state continues display after satisfying condition.
Further, described wing flats can carry out filling rear projection screen according to customer demand or not fill.
Tool of the present invention has the following advantages: multi-screen of the present invention is connected with chain sheet form by single screen, conveniently increases and decreases screen.First and second virtual screen can be complete process roll needed for indication range, calculating without the need to only carrying out complicated algorithm by a screen, directly carrying out showing, accelerating display speed, improve display efficiency.Wing flats also directly can fill display, and word only need process foreground.Wait for that screen can process when former frame shows, after display completes, wait for that screen meeting copies data is in the first and second virtual screen, saves the time.(traditional method is display one frame, then waits next frame process, then shows, have a strong impact on efficiency).Data disaply moudle is poll waiting mechanism, more reasonably utilizes timeslice to go to show lteral data.
