Description

媒体预览特效实现方法、装置及系统、服务端和计算机可读存储介质 技术领域
本申请涉及媒体预览技术领域,尤其涉及一种媒体预览特效实现方法、一种媒体预览特效实现装置、一种服务端、一种媒体预览特效实现系统以及一种计算机可读存储介质。
背景技术
在显示屏例如LED显示屏行业,用户往往需要制作一个复杂媒体,以充分使用当前屏幕来完成其商业广告的推广和展示。此处的复杂媒体的内容通常包含文字、图片、视频、RSS((Really Simple Syndication,简易信息聚合)、数字时钟、模拟时钟、日历组件和天气组件等常规媒体的多个或全部。
通常对于制作好的复杂媒体,用户往往希望在服务端就能够预览到其后续在终端的播放特效。然而,由于现有技术中的服务端无法实现终端支持的所有特效,导致在服务端的预览效果可能不是终端播放出来的效果;再者,现有的服务端预览功能支持图片的特效而无法兼容文本的特效(例如翻页特效)的预览,但由于LED显示屏行业的特殊性,对于文本的特效要求比较高。如此一来,导致服务端的用户体验度不佳。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
【第一实施例】
如图1所示,本申请实施例提供的一种媒体预览特效实现方法,例如包括以下步骤:
S11:控制使欲显示媒体页和已显示媒体页在第一方向上的尺寸与父容器在所述第一方向上的尺寸一致;
S13:控制使所述欲显示媒体页在所述父容器内的显示层级低于所述已显示媒体页在所述父容器内的显示层级;以及
S15:在特效时长内,保持所述欲显示媒体页在所述父容器内的第二方向上的尺寸不变、并控制所述已显示媒体页在所述父容器内的所述第二方向上的显示尺寸从初始尺寸逐渐减小至零,其中所述初始尺寸等于所述父容器在所述第二方向上的尺寸。
具体地,在步骤S11中,所述已显示媒体页和所述欲显示媒体页例如同为文本媒体页或同为图片媒体页。再者,以图2所示为例,欲显示媒体页div1和已显示媒体页div2为父容器21的元素,父容器21的水平宽度(第一方向上的尺寸)和竖直高度(第二方向上的尺寸)例如分别记为W和H,则欲显示媒体页div1和已显示媒体页div2的宽度(第一方向上的尺寸)设置为一致,都为父容器21的宽度W。此处的父容器例如是用来包含目标元素的容器,而div1及div2为父容器所包含的元素。
在步骤S13中,仍以图2所示为例,欲显示媒体页div1在父容器21内的显示层级低于显示媒体页div2在父容器21内的显示层级,从而欲显示媒体页div1被压在下面,已显示媒体页div2展示在上面。此处值得一提的是,div1及div2在父容器21内的显示层级也即对应div1及div2在父容器21内的层叠顺序。
在步骤S15中,仍以图2所示为例,在特效时长内,保持欲显示媒体页div1在父容器21内的高度(第二方向上的尺寸)不变、并控制已显示媒体页div2在父容器21内的显示高度(第二方向上的显示尺寸)从初始尺寸逐渐减小至零,其中所述初始尺寸典型地等于父容器21的高度H。
为便于更清楚地理解本实施例的媒体预览特效实现方法,下面结合图3A、图3B和图4并以已显示媒体页在父容器的高度方向上以向下展开方式逐渐露出欲显示媒体页为例进行说明。本实施例是基于JS(JavaScript)代码由发明人自主开发的高度算法和Top算法来实现特效预览功能。具体地:
参见图3A,假如欲显示媒体页为第1页,则将预览页面的背景色例如黑色作为已显示媒体页,也即为第0页;那么第1页在父容器内是显示在下方的,而第0页在父容器内是显示在上方的。之后,第1页在父容器内的高度不变,第0页在父容器内的显示高度逐渐变小以逐渐露出第1页;具体地,第0页的显示高度从父容器的高度H(对应初始尺寸)逐渐变为0,且在显示高度逐渐变小的过程中,第0页的显示高度动态值满足关系式:height=H–countNow*everyHeight;其中countNow表示特效时长内当前为第几 次刷新,everyHeight表示单次刷新所减少的尺寸。此外,从图3A还可以看出:第1页是以依次露出1行文字、3行文字、5行文字、7行文字和9行文字的方式进行显示,而第0页的显示高度逐渐减小,从而达成文本翻页特效。
类似地,参见图3B,假如欲显示媒体页为第2页,那么第2页在父容器内是显示在下方的,而第1页在父容器内是显示在上方的。之后,第2页在父容器内的高度不变,第1页在父容器内的显示高度逐渐变小以逐渐露出第2页;具体地,第1页的显示高度从父容器的高度H(对应初始尺寸)逐渐变为0,且在显示高度逐渐变小的过程中,第1页的显示高度动态值同样满足关系式:height=H–countNow*everyHeight。此外,从图3B还可以看出:第2页是以依次露出1行文字、2行文字、5行文字、7行文字和9行文字的方式进行显示,而第1页则是从顶部开始依次去除掉1行文字、2行文字、5行文字、7行文字和9行文字,从而达成文本翻页特效。
至于everyHeight和countNow,其可以基于如下的Top算法获取。
承上述,参见图4,以文本媒体为例,文本媒体例如基于父容器的尺寸(比如高度H)被划分成N个媒体页,也即第1页至第N页,各个媒体页的初始端部值initTop分别为0至(N-1)H。Top算法例如是:假设欲显示媒体页是第N页,盖在上一层的就是第N-1页、且其初始端部值(例如初始顶部值)initTop=(N-2)H;为了使得特效执行的比较流畅,预设特效时长time内的刷新总次数例如为count=100,这样就会timeStep=time/count秒刷新一次,这里是定时器的间隔;每次刷新的高度(也即单次刷新所减少的尺寸)为:everyHeight=H/count;根据CSS(Cascading Style Sheet,层叠样式表)的定位(position)属性中的绝对(absolute)定位规则,端部值top=0–initTop–everyHeight*countNow=0–(N-2)H-(H/count)*countNow;此处的countNow表示特效时长time内当前为第几次刷新(也即定时器执行到了第几次),端部值top在特效时长time内是动态变化的,其是用来确定已显示媒体页在父容器中的显示内容,也即已显示媒体页的显示内容在整个文本媒体中的位置的重要参数。由此可见,Top算法主要用来实现显示内容的定位。此处值得一提的是,CSS众所周知是一种定义样式结构如字体、颜色、位置等的语言,例如为用来表现HTML或XML等文件样式的计算机语言。
另外,需要说明的是,图3A、图3B和图4是以已显示媒体页在父容器的高度方向上以向下展开方式逐渐露出欲显示媒体页为例进行说明的,但本申请实施例并不以此为限,在第二方向为父容器的高度方向时,已显示媒体页也可以是在父容器的高度方向上以向上展开方式(图3C)逐渐露出欲显示媒体页、或 已显示媒体页在父容器的高度方向上以上下展开方式(图3D)逐渐露出欲显示媒体页、或已显示媒体页在父容器的高度方向上以上下合并方式(图3E)逐渐露出所述欲显示媒体页。当然,也可以理解的是,当第二方向为父容器的宽度方向时,已显示媒体页可以是在父容器的宽度方向上以向左展开方式逐渐露出欲显示媒体页、或已显示媒体页可以是在父容器的宽度方向上以向右展开方式逐渐露出欲显示媒体页、或已显示媒体页在父容器的宽度方向上以左右展开方式逐渐露出欲显示媒体页、或已显示媒体页在父容器的宽度方向上以左右合并方式逐渐露出所述欲显示媒体页;这些不同的方式所采用的高度算法、Top算法的原理和机制是一样的,只是需要对高度算法和Top算法所采用的前述公式进行微调。再者,值得一提的是,对于图片媒体,通常图片媒体的大小为单个媒体页,也即其尺寸与父容器的尺寸一致,因此在利用前述实现方法进行特效预览时,通常只能观察到第1页的特效,而后续页由于内容是和第1页相同,从而人眼视觉上不容易察觉。
简而言之,本实施例基于一套利用高度算法和Top算法的机制来实现预览功能中的图片、文本甚至是RSS的各种特效,只需维护一套代码,降低了开发成本。再者,以文本媒体为例,对于翻页特效,其基于高度算法和Top算法采用逐渐改变高度、逐渐改变定位位置的方式,可以实现两页文本的无缝替换,无黑场。
【第二实施例】
参见图5A,本申请实施例还提出一种媒体预览特效实现装置51,其可以执行前述实施例的媒体预览特效实现方法。具体来说,本实施例的媒体预览特效实现装置51例如包括:尺寸控制模块511、显示层级控制模块513和特效控制模块515。其中,尺寸控制模块511、显示层级控制模块513和特效控制模块515例如分别用于执行前述第一实施例的步骤S11、S13和S15,因而各个模块的功能细节在此不再赘述。
此外,当所述已显示媒体页和所述欲显示媒体页为同一个文本媒体中依序显示的两个媒体页面时,如图5B所示,媒体预览特效实现装置51还包括端部值计算模块514,用于:每一次刷新时,根据层叠样式表的定位属性的绝对定位规则计算所述已显示媒体页在所述文本媒体中的端部值,以确定所述已显示媒体页在所述父容器中的显示内容。此处的文本媒体例如为只包含文字、符号、数字和换行标记的媒体。
另外,值得一提的是,尺寸控制模块511、显示层级控制模块513和特效控制模块515、甚至端部值计算模块514,可以是软件模块而存储于存储器中、 并可由一个或多个处理器执行。
【第三实施例】
参见图6,本申请实施例还提出一种服务端60,用于预览复杂媒体并发布复杂媒体至终端例如701~70m进行播放。其中,服务端60具有预览模块61,且预览模块61可以是软件模块,存储在服务端60的存储器上并可以由服务端60上的一个或多个处理器执行来实现前述第一实施例中的媒体预览特效实现方法。
更具体地,用户可以通过浏览器输入网址登入服务端60来进行复杂媒体编辑制作、特效预览等操作,并将制作好的复杂媒体与终端例如701~70m中的一个或多个绑定,从而终端例如701~70m可以跟服务端60进行心跳交互获取复杂媒体在本地进行播放、并送至显示屏例如LED屏上显示。复杂媒体例如包含文字、图片、视频、RSS((Really Simple Syndication,简易信息聚合)、数字时钟、模拟时钟、日历组件和/或天气组件等常规媒体,也即是多个常规媒体的集合体。再者,作为举例,终端例如701~70m可以是Android媒体播放盒,其可以带载LED显示屏或LCD显示屏,甚至其他显示屏。典型地,Android媒体播放盒主要包含嵌入式处理器(例如ARM处理器)和可编程逻辑器件(例如FPGA),且嵌入式处理器可以安装运行Android系统。
本实施例基于前述高度算法和Top算法,解决了文本媒体在服务端预览的特效问题,兼容文本和图片媒体的特效预览,和终端的播放特效一致;从而可以简化用户制作复杂媒体的流程,直接可以在服务端看到最终播放出来的效果。
【第四实施例】
参见图7,本申请实施例还提出一种媒体预览特效实现系统80,包括存储器81以及耦合至存储器81的至少一个处理器83,所述至少一个处理器83被配置成执行前述第一实施例所述的媒体预览特效实现方法,也即当媒体预览特效实现系统80运行时,所述至少一个处理器83读取所述存储器81存储的程序代码以执行所述媒体预览特效实现方法。概述之,处理器83被配置成:(a)控制使欲显示媒体页和已显示媒体页在第一方向上的尺寸与父容器在所述第一方向上的尺寸一致;(b)控制使所述欲显示媒体页在所述父容器内的显示层级低于所述已显示媒体页在所述父容器内的显示层级;以及(c)在特效时长内,保持所述欲显示媒体页在所述父容器内的第二方向上的尺寸不变、并控制所述已显示媒体页在所述父容器内的所述第二方向上的显示尺寸从初始尺寸逐渐减小至零,其中所述初始尺寸等于所述父容器在所述第二方向上的尺寸,所述第二方向与所述第一方向不同。其中,各个功能(a)、(b)及(c)的具体细节可参考前述第一实 施例中的步骤S11、S13及S15的相关详细描述,故在此不再赘述。
【第五实施例】
参见图8,本申请实施例还提出一种计算机可读存储介质90。所述计算机可读存储介质90为非暂态存储器,且存储有程序代码;所述程序代码包括用于执行前述第一实施例的媒体预览特效实现方法的指令。概述之,所述程序代码所包括的所述指令用于被一个或多个处理器执行时:(i)控制使欲显示媒体页和已显示媒体页在第一方向上的尺寸与父容器在所述第一方向上的尺寸一致;(ii)控制使所述欲显示媒体页在所述父容器内的显示层级低于所述已显示媒体页在所述父容器内的显示层级;以及(iii)在特效时长内,保持所述欲显示媒体页在所述父容器内的第二方向上的尺寸不变、并控制所述已显示媒体页在所述父容器内的所述第二方向上的显示尺寸从初始尺寸逐渐减小至零,其中所述初始尺寸等于所述父容器在所述第二方向上的尺寸,所述第二方向与所述第一方向不同。其中,各个功能(i)、(ii)及(iii)的具体细节可参考前述第一实施例中的步骤S11、S13及S15的相关详细描述,故在此不再赘述。
