动态式多图像层混合器、其方法及其播放器 Dynamic mixer multi-layer image, which method and player

技术领域 FIELD

[0001] 本发明是有关于一种多图像层混合器,且特别是有关于一种动态式多层图像混合器、其方法与其播放器。 [0001] The present invention relates to a multi-layer image mixer, and more particularly to a dynamic type mixer relates to a multilayer image, which method and its player.

背景技术 Background technique

[0002]目前多媒体视频技术发展迅速,且随着晶片运算能力越来越强大的趋势,显示器所播出的画面会包括多个图像层,例如:主图像层、画面上显示(on-screen display,简称为OSD)图像层、字幕图像层与游标图像层。 [0002] It multimedia video technology developed rapidly, and more and more powerful computing capability as the wafer tendency, the display screen will be broadcast on a plurality of images comprising layers, for example: a main image layer, display (on-screen display on a screen , referred to as OSD) image layer, a subtitle image with a cursor image layer layer. 目前一般的播放器皆会预先定义可以处理的图像层数目,然而,这种播放器无法播放超出已定义的图像层数目的画面。 The general player will all predefined number of image layers that can be processed, however, the player can not play beyond the screen image defined number of layers. 假设播放器可支援到具有3个图像层的画面,如果所显示的画面所包括的多个图像层超过3层,例如,具有6个图像层的画面,则此播放器并无法播放具有6个图像层的画面。 Suppose the player supports a screen image having three layers, the plurality of images displayed layer picture, if included in more than three layers, e.g., with a screen image layer 6, and the player can not play this with 6 screen image layer. [0003] 为了解决上述的问题,目前有一些多媒体晶片业者提出了一种可以处理超出已定义的图像层数目的画面的播放器,此种播放器主要是使用2维图像引擎将超出的图像层数目的任两个图像层混合为一个图像层,并将混合后的图像层与另一个图像层混合,再产生另一个混合图像层,直到剩下一个混合图像层为止。 [0003] To solve the above problems, there are some multimedia chip industry presents a number of layers that are beyond the screen image defined player, such player is mainly two-dimensional image using an image layer would exceed the engine any number of layers mixing two images into one image layer, the image layer and the image layer was mixed with another mixture, then mixed to generate another image layer until a rest layer until the mixed image. 另外,此种播放器具有显示引擎,此显示引擎可以处理具有定义的图像层数目的画面。 Further, such a player having a display engine, this engine can process the image display screen having a defined number of layers. 播放器混合显示引擎所处理的定义的图像层数目的多个图像层与2维图像引擎所最后输出的混合图像层,以产生一个混合画面于播放器的显示萤幕上播放。 The player displays the mixed image mixing layer image object of a plurality of image layers engines processed layers defined in the last two-dimensional image outputted from the engine to produce a mixed picture displays on the display screen of the player. 如此,上述的播放器将可以播放超出定义的图像层数目的画面。 Thus, the above-described player can play the number of layers beyond the screen image definition.

[0004] 举例来说,播放器所定义的图像层数目为3,对于具有10个图像层的画面而言,播放器的2维图像引擎会将另外7个图像层的任两个先混合成一个图像层,接着,将混合的图像层与另一个图像层混合,直到剩下一个混合图像层为止。 [0004] For example, the number of the player image layer 3 is defined, for a picture having the picture layer 10, any two of the two-dimensional image of the player engine 7 will be further mixed to a first image layer a picture layer, and then, the mixed layer of the image is mixed with another image layer until a rest layer until the mixed image. 换言之,2维图像引擎共有执行6次的图像层混合操作。 In other words, a total of two-dimensional image engine performs an image layer 6 times the mixing operation. 接着,显示引擎会处理3个图像层,播放器会将2维图像引擎最后所输出的混合图像层与显示引擎所处理的3个图层数目混合成一混合画面,并将此混合画面于播放器的显示萤幕上播放。 Next, the display engine processes the three image layers, the number of mixed layer 3 player engine will last two-dimensional image outputted to the display layer of the mixed image processing engine into a mixed picture, and this picture to a mixed player the show played on the screen.

[0005] 另外,也有一些多媒体晶片业者提出利用软体演算法,先行将超出的图像层数目的任两个图像层混合为一个图像层,接着,将混合的图像层与另一个图像层混合,直到剩下一个混合图像层为止。 [0005] In addition, there are some multimedia industry proposed wafer using software algorithms, the preceding image would exceed the number of layers of any two image layers are combined into one image layer, and then, the mixed layer of the image is mixed with another image layer until a mixed until the remaining image layer. 如此将耗费大量存储器频宽,且混合图层亦耗费许多的时间。 Thus takes a lot of memory bandwidth, and mixed layer also takes a lot of time.

[0006] 简言之,目前的播放器可能无法播放超出定义的图像层数目的画面,或者虽然有些的播放器可播放超出定义的图像层数目的画面,但这些播放器必须使用2维图像引擎对其他的图像层进行混合。 [0006] In short, the current player may not play beyond the screen image layers defined purpose, or although some players can play beyond the screen image defined number of layers, but these players must use two-dimensional graphics engine mixing of the other image layers. 然而,2维图像引擎在每一次进行图像层混合操作时,都需要自存储器读取图像层数据与将混合图层数据写入至存储器,而造成存储器频宽的浪费。 However, the engine 2-dimensional image at each image layer mixing operation, all need to read image data layer and the waste mixed layer data is written to the memory, the memory bandwidth resulting from the memory. 特别是在需要进行多次图像层混合操作时,所浪费的存储器频宽更是非常地庞大。 In particular, when mixing operation is required many times the image layer, the wasted memory bandwidth is very large.

具体实施方式 Detailed ways

[0038] 请参照图1,图I是本发明实施例所提供的具有多个图像层的画面的示意图。 [0038] Referring to FIG. 1, FIG. I is a schematic diagram of a screen image having a plurality of layers according to an embodiment of the present invention. 如同图I所示,画面100包括了多个图像层LI〜L5与空画面101,空画面101为画面100中未被图像层LI〜L5所覆盖的区域。 As shown in FIG. I, the screen 100 includes a plurality of image layers LI~L5 empty screen 101, screen 101 is empty screen 100 is not covered by the image layer LI~L5 area. 本发明的实施例所提供的动态式多图像层混合器或方法可以处理如同图I的具有多个图像层LI〜L5的画面100,而且画面100的多个图像层LI〜L5的图像层数目并非用以限定本发明,除此之外,多个图像层LI〜L5之间更可以彼此重迭(overlap)。 Dynamic mixer or a multi-layer image Embodiments of the present invention may be provided as a screen having a plurality of image processing LI~L5 layer 100 of FIG I, and the number of the plurality of image layers screen 100 of the image layer LI~L5 not intended to limit the present invention, in addition, between a plurality of images may overlap each other more layers LI~L5 (overlap).

[0039] 动态式多图像层混合器或方法在处理具有多个图像层LI〜L5的画面100时,会使用扫描线逐一地扫描画面100,并混合与处理扫瞄线于画面上所涵盖的图像层。 [0039] The dynamic type mixer or a multi-layer image processing method when a screen having a plurality of image layers LI~L5 100, uses the scanning lines one by one scan screen 100, and mixed with the processed scan lines on the screen covered image layer. 换言之,每一次仅输出与处理画面100的一笔线数据。 In other words, only once every processing an output line 100 of the screen data. 要说明的是,虽然图I是以水平扫描线为例,但在其他的应用中,扫描线亦可能是垂直扫描线。 It is noted that, although FIG. I is a horizontal scanning line, for example, in other applications, the scan lines may also be vertical scanning lines.

[0040] 另外,每一个图像层所具有的像素数据是存于存储器当中,且每一个图像层具有一个标头档。 [0040] Further, the pixel data of each image layer with which is stored in the memory, and each image layer has a header file. 所述标头档用以纪录图像层的宽度、高度、色彩信息、格式与图像层位置,图像层位置一般包括了图像层水平起始与结束位置、图像层垂直起始与结束位置。 The header file record image layer to the width, height, color information, position format image layer, the image layer comprising an image layer position generally perpendicular to the horizontal start and end the start position and end position, the image layer. 画面100的高度、宽度、色彩信息、格式与画面位置则纪录于画面100的标头档。 Height, width, color information, picture format and position on the screen 100 is to record the picture header file 100.

[0041] 在图I中,水平扫描线会从画面100的最顶端逐一扫描至画面100的最底端,动态式多图像层混合器或方法在每一次进行水平扫描后,都会混合于扫描线上的图像层,并输出画面100的一笔线数据给后端的视频解码器解码,以将此笔线数据于显示萤幕上播放。 [0041] In Figure I, the horizontal scan lines will be scanned one by one to the bottom of the screen 100 from the top of the screen 100, a dynamic mixer or a multi-layer image method after each horizontal scanning, the scanning lines are mixed layer image, and outputs the sum data line 100 to the rear end of the screen of the video decoder decodes to play this line data to the pen on the screen display. 在此以水平扫描线102扫描所述画面100为例来说明。 In the horizontal scanning lines 102 to scan the screen 100 will be explained as an example. 首先,使用水平扫描线102会扫瞄出画面100于水平扫描线上每一个图像层的图像层水平起始与结束位置,其中每一个图像层的图像层水平起始与结束位置是藉由进行全域标头档搜寻(global header search)来搜寻图像层的标头档而得到。 First, the horizontal scanning lines 102 will scan the screen of the image layer 100 on the horizontal scanning line of each of the horizontal image start and end positions of the layer, wherein each of the horizontal image layer picture layer start and end position are carried out by global header file search (global header search) to search the image layer header file obtained.

[0042] 在图I中,画面100的画面水平起始与结束位置分为O与1215。 [0042] In Figure I, the screen horizontal screen 100 is divided into start and end positions O and 1215. 经过水平扫描线102扫描后,可以得知共有4个图像层LI〜L3、L5位于扫描线102上,并且据此搜寻图像层LI〜L3、L5的标头档,以找出图像层LI〜L3、L5的图像层水平起始与结束位置。 After scanning the horizontal scanning lines 102, that may be a total of four image layers LI~L3, L5 located on the scanning line 102, and accordingly the search image layer LI~L3, L5 header file to identify image layer LI~ horizontal image layer L3, L5 start and end position. 图像层LI的图像层水平起始与结束位置分别为100与1115,图像层L2的图像层水平起始与结束位置分别为110与700,图像层L3的图像层水平起始与结束位置分别为120与320,图像层L5的图像层水平起始与结束位置分别为520与715。 The image layer horizontal start and end positions of the image layer LI 100 and 1115, respectively, the horizontal image start and end position of layer image layer L2 110 and 700, respectively, the horizontal image start and end position of layer image layer L3, respectively 120 and 320, the image layer L5 level horizontal image start and end positions 715 and 520 respectively.

[0043] 接着,根据水平扫描线102上的每一个图像层的图像层水平起始与结束位置以及所述画面的画面水平起始与结束位置,将所述扫描线102分成多个区段,且记录每一个区段的区段宽度与区段图像层数目。 [0043] Next, the horizontal image start screen horizontal layers each image layer 102 on the horizontal scanning lines start and end position and the end position of the screen, the scan lines 102 into a plurality of sections, and the width of the image segment and the number of layer sections each section of record. 在此要说明的是,动态式多图像层混合器更可以因应缓冲器的有无,而进行即时性运算或先纪录各图像层,因此,在此情况下,可以不用先记录每一个区段的区段宽度与区段图像层数目。 Be described herein, the dynamic mixer further multi-layer image may be in response to the presence or absence of a buffer, or performing real-time operation to record the image layers, and therefore, in this case, can not record a first section of each the width of the image segment as the number of layers.

[0044] 例如,在图I中,水平扫描线102会被分为9个区段seg_l〜seg_9。 [0044] For example, in FIG I, the horizontal scanning line 102 is divided into nine sections seg_l~seg_9. 区段seg_l的区段宽度为100,且没有任何的图像层涵盖,因此其图像层数目为O。 Seg_l section width section 100, an image without any cover layer, so that the number of image layers is O. 区段seg_2的区段宽度为10,且有图像层LI涵盖,因此其图像层数目为I。 Seg_2 section width section 10 is, and the image covering layer LI, therefore the number of image layers is I. 区段seg_3的区段宽度为10,且有图像层LI、L2涵盖,因此其图像层数目为2。 Seg_3 section width section 10, and the image layer LI, L2 covering, so that the number of image layer 2. 区段seg_4的区段宽度为200,且有图像层LI〜L3涵盖,因此其图像层数目为3。 Seg_4 section width section 200, and the image layer LI~L3 cover, so that the number of image layer 3. 区段seg_5的区段宽度为200,且有图像层L1、L2涵盖,因此其图像层数目为2。 Seg_5 section width section 200, and the image layers L1, L2 covering, so that the number of image layer 2. 区段seg_6的区段宽度为180,且有图像层L1、L2、L5涵盖,因此其图像层数目为3。 Seg_6 section width section 180, and the image layer L1, L2, L5 covering, so that the number of image layer 3. 区段seg_7的区段宽度为15,且有图像层L1、L5涵盖,因此其图像层数目为2。 Seg_7 section width section 15 is, and the image layer L1, L5 covering, so that the number of image layer 2. 区段seg_8的区段宽度为400,且有图像层LI涵盖,因此其图像层数目为I。 Section width is seg_8 section 400, and the LI layer covering the image, so the number of image layers is I. 区段seg_9的区段宽度为100,且没有任何的图像层涵盖,因此其图像层数目为O。 Seg_9 section width section 100, an image without any cover layer, so that the number of image layers is O.

[0045] 接着,根据每一个区段的区段宽度与区段图像层数目混合区段所涵盖的图像层的数个像素点,以产生所述区段所对应的区段混合画面的像素点。 [0045] Next, the number of pixels of the picture layer section width and number of sections of the picture layer of the mixing section each section covered, mixed to generate screen pixels corresponding section of the section . 更进一步地说,各区段是分别根据其区段与区段图像层数目、各图像层的标头档所夹带的图像层水平起始与结束位置、图像层垂直起始与结束位置,来混合各区段所涵盖的图像层的数个像素点,以产生所述区段所对应的区段混合画面的像素点。 More particularly, each section respectively according to the number of its zone and the zone of the picture layer, picture layer header file for each image layer is entrained horizontal starting to mix with the end position, the start and end position of the vertical image layer a plurality of image pixels covered by each section layer to produce a mixed picture pixels corresponding to the segment section. 除此之外,各图像层的标头档所夹带的水平起始与结束位置与垂直起始与结束位置是根据之前所进行的全域标头档搜寻而得到。 In addition, the header file of the image layers entrained horizontal start position and end position of the vertical start and end are obtained in accordance with the global header file search performed before.

[0053] 接着,请参照图3,图3是本发明实施例所提供的多图像层混合器203的系统方块图。 [0053] Next, referring to FIG 3, FIG. 3 is an embodiment of the multi-image layer mixer is provided a system block diagram 203 of the embodiment of the present invention. 多图像层混合器203包括了全域标头档搜寻器301、动态存储器信息模块302、混合器303、静态存储器305、缓冲器304。 Multi-layer image mixer 203 comprises a global header file searcher 301, dynamic information storage module 302, a mixer 303, a static memory 305, buffer 304. 全域标头档搜寻器301的第一输出端连接于动态存储器信息模块302的第一输入端,全域标头档搜寻器301的输入输出端连接于动态存储器仲裁器311的第一输入输出端,动态存储器信息模块302的输入输出端连接于动态存储器仲裁器311的第二输入输出端,混合器303的第一与第二输入端分别连接于动态存储器信息模块302与静态存储器305的输出端,混合器303的输出端连接于缓冲器304与静态存储器305的输入端,且动态存储器仲裁器311的第三输入输出端连接于动态存储器312的输入输出端。 A first output terminal of the global header file finder 301 is connected to a first input of dynamic information storage module 302, the input and output global header file finder 301 is connected to a first dynamic memory arbiter input and output terminals 311, dynamic memory of the information input and output module 302 is connected to a second input-output port dynamic memory arbiter 311, a first mixer and a second input terminal 303 are respectively connected to the output dynamic memory 302 and a static memory module information 305, the output of the mixer 303 is connected to the input of the buffer 304 and a static memory 305, and the third input and output dynamic memory arbiter 311 is connected to the input and output terminals of the dynamic memory 312.

[0054] 进行多图像层混合操作的方式是采用渐进式扫描的顺序来完成,也就是一次以一条扫描线为单位来产生一条多图像层混合线画面。 [0054] The multi-layer image mixing operation mode is the use of progressive sequential scanning is accomplished, i.e. once to a scanning line to produce a multi-layer hybrid wire screen image units. 全域标头档搜寻器301会接收水平与垂直同步信号,以得知何时需进行全域标头档搜寻。 Global header file searcher 301 receives horizontal and vertical sync signals, in order to know when the need for global header file search. 全域标头档搜寻器301会进行全域标头档搜寻,透过其第一输入输出端指示动态存储器仲裁器311向动态存储器312要求所有的图像层的标头档所夹带的信息。 Global header file 301 will search for the global header file search, indicates that the dynamic memory arbiter input-output port through which a first request for information header file 311 for all the picture layer entrained to the dynamic memory 312. 全域标头档搜寻器301可根据水平与垂直同步信号得知目前水平扫描线对应画面的位置,并且据此扫描出所述画面于水平扫描线上的每一个图像层的图像层起始与结束位置。 Global header file finder 301 can know the current position of the picture corresponding to the horizontal scanning line in accordance with horizontal and vertical sync signals, and accordingly the scanned image layer layer each image in the horizontal scanning line of the picture start and end position. 更进一步地说,可以藉由各图像层的标头档所包括的图像层水平起始与结束位置、图像层垂直起始与结束位置来得知所述画面于水平扫描线上被哪几个图像层所涵盖,并得到画面于水平扫描线上的每一个图像层的图像层起始与结束位置。 More particularly, the image layer may be horizontal by the respective header file included in the picture layer start and end positions, the start and end position of the vertical layer that the image is a screen image in which several horizontal scanning lines the covering layer, and to obtain a picture in the picture layer for each horizontal scanning line of the picture layer of the start and end position.

[0055] 接着,全域标头档搜寻器301会根据水平扫描线上的每一个图像层的图像层水平起始与结束位置以及所述画面的画面水平起始与结束位置,将所述水平扫描线分成多个区段,且记录每一个区段的区段宽度与区段图像层数目。 [0055] Next, the global header file 301 will search the end position of the screen depending on the starting level of the picture layer of each horizontal scanning line of the picture layer of the horizontal position and the start and end of the picture, the horizontal scanning line into a plurality of segments, the number of sections and the recording width of the image of layer sections each section. 在此要说明的是,动态式多图像层混合器203更可以因应缓冲器的有无,而进行即时性运算或先纪录各图像层,因此,在此情况下,可以不用先记录每一个区段的区段宽度与区段图像层数目。 Be described herein, the dynamic multi-layer image mixer 203 can also be due to the presence or absence of a buffer, or performing real-time operation to record the image layers, and therefore, in this case, can not record to each zone the width of the image segment segment segment number of layers. 接着,全域标头档搜寻器301会一次根据一个区段的区段宽度、区段图像层数目与水平扫描线上的每一个图像层的图像层起始与结束位置依序产生不同的存储器地址给动态存储器信息模块302。 Next, the global header file searcher 301 may produce a different memory address sequentially according to the start and end position of the picture layer of the picture layer of each section width of a segment, segment the image layer with the horizontal scanning line number The memory module 302 to the dynamic information. 这些存储器地址依序让动态存储器信息模块302获得区段上的不同图像层的多个像素点,其中像素点的数目小于或等于区段宽度,并且使得混合器303将区段上的所有图像层的多个像素点混合为一个区段混合画面中的多个像素点后,才会将区段混合画面中的多个像素点输出给缓冲器304暂存。 These in turn allows the dynamic memory address information of the memory module 302 obtains a plurality of images of different layers of pixel points on the segments, wherein the number of pixels is less than or equal to the section width, and so on all the image layers mixer section 303 after mixing the mixing the plurality of pixels a plurality of pixels of a picture section, a plurality of pixels before mixing sections to the picture output buffer 304 temporarily stores.

[0056] 动态存储器信息模块302根据全域标头档搜寻器301所产生的存储器地址,透过其第二输入输出端指示动态存储器仲裁器311向动态存储器312要求区段上的一个图像层的多个像素点数据,并将此些像素点送给混合器303,其中像素点的数目等于区段宽度。 [0056] Dynamic memory module 302 according to the memory address information global header file generated by the search engine 301, indicating a dynamic memory arbiter output terminal through a second input 311 to a dynamic image memory 312 requires a multi-layer on the segments pixel data points, and points to the pixels of such a mixer 303, wherein the number of pixels is equal to the section width. 在处理每一个区段中的数个像素点时,静态存储器305都会先抹除其储存的像素点。 When processing a plurality of pixels in each section, static memory 305 are erased before storing the pixel. 混合器303混合静态存储器305所储存的多个像素点与动态存储器信息模块302所输出的多个像素点,并且将混合后的多个像素点送给静态存储器305储存。 Mixer static mix more than 303 pixels stored in memory 305 and dynamic information memory module over 302 pixels output, and a plurality of pixels of the mixed static memory 305 to the storage. 等到,区段中所有的图像层的多个像素点都被混合完毕后,混合器303所输出的多个像素点会被缓冲器304所暂存,且静态存储器305会抹除其储存的像素点,其中此时的混合器303所输出的多个像素点就是区段混合画面中的多个像素点。 Until all of the plurality of pixels of the picture layer segment have been completed after the mixing, over 303 pixels output from the mixer will be the temporary buffer 304, and a static memory 305 erases pixels which will be stored point, the plurality of pixels a plurality of pixels at this time is output from the mixer 303 is the section in which the mixed picture. 缓冲器304除了用以暂存区段混合画面的多个像素点之外,其输出的数据单位可以是一个长字元大小,亦即8个位元组大小;但在实际应用上,缓冲器304的储存空间大小可以依实际需求做选择。 In addition to buffer 304 for temporarily storing a plurality of screen pixels mixing zone outside its data output unit may be a long character size, i.e. the size of eight bytes; but in practice, the buffer storage space 304 can make choices according to actual needs.

[0057] 请同时参照图I与图3,全域标头档搜寻器301在水平扫瞄线102对画面100进行扫描时,便会扫描出所述画面100于水平扫描线102上的每一个图像层的图像层水平起始与结束位置,而且全域标头档搜寻器301更会根据水平扫描线102上的图像层LI〜L3与L5的图像层水平起始与结束位置以及所述画面100的画面水平起始与结束位置,将所述水平扫描线102分成多个区段seg_l〜seg_9,且记录每一个区段的区段宽度与区段图像层数目。 [0057] Please refer to FIGS.
