Embodiment
By specifying technology contents of the present invention, structural attitude, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
The present technique scheme has defined several viewing areas in advance, shows that in advance task can be classified under the corresponding catalogue before not showing, program can be carried out convergent-divergent to picture, video output, is to splice, be full of whole screen at last.
See also Fig. 1, the dispatching method that the present invention provides a kind of split screen to show,
May further comprise the steps:
S100: create preparatory demonstration task, comprise display condition in the demonstration task in advance;
S200: periodically whether detection also has preparatory demonstration task to be untreated, if having, is stored in the internal memory then with decoding of demonstration task in advance and convergent-divergent, and with the data that obtain; If there not be the task of showing in advance, or show that in advance task all handles, then do not carry out the processing of decoding and convergent-divergent and operate;
S300: the preparatory demonstration task that periodic queries has been handled; If current point in time equals or is later than the shown time point of preparatory demonstration task; Then show the preparatory demonstration task of having handled, if current point in time does not then show early than the shown time point of preparatory demonstration task.
So-called demonstration task in advance is meant and will on display interface, shows in the present embodiment, does not still also begin the scheme that shows.
The split screen dispatching algorithm has not only comprised scheduling; The decoding and the pre-service of picture or video etc. have also been comprised; Its pre-service comprises carries out convergent-divergent to the size of picture, concrete, and what convergent-divergent adopted is disclosed cubic spline interpolation convergent-divergent algorithm; This algorithm is those skilled in that art's technique known, just repeats no more at this.Consult Fig. 3, demonstrated among the figure that existing 3 split screen picture materials are decoded in proper order and the process of instant playback, the i.e. situation of three preparatory demonstration tasks.Preparatory demonstration task described in this technical scheme is the processing unit of band time tag, viewing area.Time shaft among the figure is for the time that shows picture materials decoding needs and in each time period, handles which kind of task.Three preparatory demonstration tasks (can be picture) among the figure are processed respectively in time shaft, and promptly decoded and convergent-divergent is whenever handled the scheme that a pictures just shows immediately; This technical scheme is decoded and instant playback in proper order, can not show task simultaneously, consults Fig. 4; If switch to 3 split screen Show Styles from 2 split screen Show Styles; After the switching, split screen 3 content displayed possibly still be the content of split screen 2 before switching on the screen, can't realize the purpose of instantaneous switching.
In the present technique scheme; 2 panes is when showing; Three decoded, convergent-divergents of preparatory demonstration task that 3 panes comprises; Make it each viewing area in the predefine 3 panes show and will decode after preparatory demonstration task be stored in the internal memory, by the time can show that time point one arrives, in the viewing area of appointment, show with regard to the while; Concrete; The viewing area is predefined; When creating preparatory demonstration task, will demonstration task in advance decode, can preestablish described display condition before the convergent-divergent, comprise the viewing area that can show time point, task, the address of data storage in internal memory that task is decoded and obtained; Come the polymerization material through the glue file clip directory at last, because the preparatory demonstration task more than two of said establishment can show that time point is identical.Thereby preparatory demonstration task can be shown simultaneously on a screen.
Consult Fig. 5, shown the realization principle of split screen display scheduling method among the figure, this demonstration task in advance has three, is respectively three pictures that show in advance, and as seen from the figure, said preparatory demonstration task is the processing unit of band time tag, viewing area.On time shaft, 3 pictures materials are decoded respectively and dispatched, the decoding first pictures material earlier, and be stored in the storage unit, other two pictures materials and the like.After the picture decoding was accomplished, the display condition according to the preparatory demonstration task of creating configured the viewing area of each picture on display screen, after can reaching the demonstration time, Showed Picture on each viewing area at display screen simultaneously.The present technique scheme; Show that the shown time point that preestablishes three preparatory demonstration tasks is identical in order to ensure under the split screen pattern time, can show that time point obtains through preset processing of current point in time adding system T.T.; Therefore need obtain current system supports maximum decode time; As to set the maximum processing time that this system can support decoding picture be 7 seconds, this maximum processing time can be empirical value, its confirmed support the maximum picture decoding and the upper limit of convergent-divergent time in addition; The purpose of setting like this is to guarantee that preparatory demonstration task can show when 2 panes switches to 3 panes simultaneously, has guaranteed demonstration task complete decoding simultaneously.As the picture of one 1920 * 1080 resolution of decoding and in addition convergent-divergent only need 6 seconds, the maximum processing time can be made as 7 seconds.That 3 panes switches to 1 split screen, and then the picture on the 3 panes stops the minimum maximum decode time that needs system to support, i.e. 7 seconds, could show after 7 seconds that the image of a split screen shows at the 3 panes image at least.In like manner, 3 split screens are owing to show that in advance number of tasks is 3, and the T.T. of then decoding multiply by number of tasks=7 second of preparatory demonstration task * 3=21 seconds for showing the required by task maximum processing time in advance, and therefore a split screen switches to 3 split screens needs 21 seconds time.
After obtaining the decode time of each preparatory demonstration task, need the shown time of good each task of scheduling.For each pictures material is created a software description structure; Promptly set up preparatory demonstration task; Whether setting can show the viewing area of time point, task, the address of data storage in internal memory that the task decoding obtains, and follows the decoding of demonstration task in advance, convergent-divergent, in decoding convergent-divergent process, go back periodically detection and also have image not decode; This concrete cycle can be 1 second even the littler time interval; If also have preparatory demonstration task to be untreated, then demonstration task is in advance carried out software decode and convergent-divergent, and with the data storage that obtains.The position of storage is predefined, and the present technique scheme has the cutting scheme of many covers display frame, and the content on each split screen then is aggregated in a file the inside; Material under the different files can be set at different viewing areas.The preparatory demonstration task that periodic queries has been handled if current point in time equals or be later than the shown time point of preparatory demonstration task, then shows the preparatory demonstration task of having handled, if current point in time does not then show early than the shown time point of preparatory demonstration task.The time point that each preparatory demonstration task occurs on screen is more than or equal to the current point in time decoding, the T.T. sum of convergent-divergent time of each preparatory demonstration task in addition.What set preparatory demonstration task can be to guarantee just to show after all pictures can both have been decoded the demonstration time, so as long as show that time point is all decoded at picture, all be fine after the shown time point of convergent-divergent after finishing; Situation about further, having needs picture on display, to stop the longer time.
On embedded low-end product scheme, there is not the jpeg decoder of hardware, perhaps can't be independent of Video Decoder and use, and must use master control to do software decode, like application CPU the JPEG picture is carried out software decode.On the SOC of low side (system on a chip SOC(system on a chip)) scheme, every the JPEG picture of decoding needs the more time.In addition, generally its master control frequency is lower, and for some pictures commonly used, like JPEG, decoding needs the time of labor, comparatively speaking, the procedure for displaying after having decoded, time consumption is few., after the decoding of demonstration task in advance, do not refresh, full frame this a kind of pattern is only arranged, the situation that does not exist pattern to switch with regard to full frame with the procedure for displaying of split screen.Show output if use this type of master control to do split screen, use is decoded in proper order and is shown the scheme of task, then can run into because the time-delay of decoding picture, and the purposes such as instantaneous switching simultaneously that can't accomplish various Show Styles.
In order to solve the problems of the technologies described above, the dispatching system that the present invention provides a kind of split screen to show comprises scheduling unit, control module, decoding unit, storage unit and display unit; Said scheduling unit is used to capture preparatory demonstration task; Said control module is used to analyze the relevant information of the preparatory demonstration task of scheduling unit acquisition, and the decode time, the viewing area that obtain preparatory demonstration task; The said decoding unit preparatory demonstration task of control module after analyzing that be used to decode; Said storage unit is used to store the decoded data of the preparatory demonstration task after the decoding unit decodes; Said display unit is used for showing simultaneously preparatory demonstration task.Concrete; The decoded data of said preparatory demonstration task is the rgb format data; Be not limited to the rgb format data in the present technique scheme; This method key element still in split screen area dividing, time control, the control of JPEG pre decoding, the control of demonstration time, does not limit decoded data layout; The present technique scheme is that example is explained with the rgb format just, and the example of extended formatting just repeats no more at this.Concrete, the decoded data of storing in the storage unit comprises: the address of decoded data after the demonstration time of task, the viewing area of task and task decoding are accomplished.Decoding unit in the present technique scheme can be used existing DISP decoding.With on display screen, having realized the purpose that shows simultaneously after the decoding of the demonstration task in advance completion.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes instructions of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
