Description

一种多媒体信息的输出方法、装置及存储介质 技术领域
本发明涉及多媒体信息输出技术，尤其涉及一种多媒体信息的输出方法、装置及存储介质。
背景技术
随着信息技术(Information Technology，IT)的飞速发展及人们生活水平的提高，人们对视频等多媒体信息的输出要求越来越高，多媒体信息的输出接口也越来越多样化。为了满足将多媒体信息同时在多个设备上输出显示的需求，衍生了多媒体信息的多通道输出技术。
现有技术中，多通道输出技术包括两种方案：一种是采用分时的方式，将多媒体信息通过不同的显示接口输出至显示设备；但是，采用分时的方式实现多媒体信息的多通道输出时，无法通过不同的显示接口同时将多媒体信息输出至多个显示设备，也无法将多媒体信息同时在多个显示设备上显示。另一种是通过物理硬件实现多通道输出，即每个显示接口对应一个独立的多媒体信息显示通道；通过物理硬件实现多通道输出，虽然能够同时在多个显示设备上显示多媒体信息，但是，需要每个通道单独对多媒体信息进行处理，如视频合成、缩放等；不仅增加了实现多通道输出需要的硬件成本，而且消耗了大量的硬件资源。
发明内容
有鉴于此，本发明实施例期望提供一种多媒体信息的输出方法、装置及存储介质，能够实现多通道同步输出多媒体信息，降低硬件成本。
本发明实施例的技术方案是这样实现的：
本发明实施例提供一种多媒体信息的输出方法，所述方法包括：获取源多媒体信息，对所述源多媒体信息进行合成处理得到合成多媒体信息，并存储所述合成多媒体信息；各通道获取合成多媒体信息，对获取的合成多媒体信息进行显示处理得到目标多媒体信息；各通道同步输出所述目标多媒体信息。
上述方案中，所述各通道获取合成多媒体信息，对获取的合成多媒体信息进行显示处理，包括：各通道获取存储的所述合成多媒体信息，对获取的合成多媒体信息进行显示处理；或，通道中的任意一个对所述源多媒体信息经合成处理得到的合成多媒体信息直接进行显示处理，其它通道获取存储的所述合成多媒体信息，并对获取的合成多媒体信息进行显示处理。

本发明实施例中，获取源多媒体信息，对所述源多媒体信息进行合成处理得到合成多媒体信息，并存储所述合成多媒体信息；各通道获取合成多媒体信息，对获取的合成多媒体信息进行显示处理得到目标多媒体信息；各通道同步输出所述目标多媒体信息。
这里，所述各通道同步输出所述目标多媒体信息为基于多媒体芯片的屏幕菜单式调节方式(On-Screen Display，OSD)多通道输出目标多媒体信息。
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。
本发明实施例多媒体信息的输出方法的基本处理流程，如图1所示，包括以下步骤：
步骤101，获取源多媒体信息；
具体地，多媒体芯片中的第一获取模块从总线协议(Advanced eXtensible Interface，AXI)辅设备获取源多媒体信息；
其中，所述AXI辅设备可以为双倍速率同步动态随机存储器(Double Data Rate，DDR)，所述源多媒体信息包括：1个光标层、3个视频层和3个图形层；所述光标层、视频层和图形层的数据均可通过寄存器配置，用 于所述第一获取模块进行获取。
步骤102，对所述源多媒体信息进行合成处理得到合成多媒体信息，并存储所述合成多媒体信息；
具体地，多媒体芯片中的合成处理模块将所述多媒体信息中的光标层数据、视频层数据和图形层数据进行合成，并通过AXI总线以单帧回写或连续回写的方式将所述合成多媒体信息存储至所述源多媒体信息的存储区域，所述存储区域为AXI辅设备或DDR；存储所述合成多媒体信息即对所述合成多媒体信息进行回写，对所述合成多媒体信息进行回写时，支持ARGB8888、YUV422、YUV420等多种多媒体格式；
这里，所述连续回写还包括跳帧回写，在执行所述多媒体信息回写功能时，要求各通道的水平分辨率大于128。
步骤103，各通道获取合成多媒体信息，对获取的合成多媒体信息进行显示处理得到目标多媒体信息；
具体地，各通道获取存储的所述合成多媒体信息，对获取的合成多媒体信息进行显示处理；或，通道中的任意一个对所述源多媒体信息经合成处理得到的合成多媒体信息直接进行显示处理，其它通道获取存储的所述合成多媒体信息，并对获取的合成多媒体信息进行显示处理；
其中，所述显示处理可由物理运算处理器(Physics Processing Unit，PPU)实现，所述显示处理包括对合成多媒体信息进行缩放处理和去隔行处理，缩放处理实现合成多媒体信息的分辨率至目标多媒体信息的分辨率的转换，以及合成多媒体信息的行和列在1/8至32倍范围内的缩放；所述合成多媒体信息及目标多媒体信息的视频层支持的最大显示分辨率为1920*1200，最小显示分辨率为48*48；
这里，所述各通道包括一个主通道和多个副通道，副通道依赖于主通道，所述主通道固定为开启状态，所述副通道可以为开启状态或关闭状态； 主通道和副通道支持的最大多媒体信息分辨率和最高帧率相同，最大多媒体信息分辨率为1920*1200，最高帧率可由通道的工作频率决定，如最高帧率达到1080ps@60fps时，对应的通道的作频率为148.5MHz；主通道和副通道各有一个RGB888格式的单色背景层，该单色背景层由寄存器进行设置，不需要从外部读取；
本发明实施例中，由主通道对所述源多媒体信息经合成处理得到的合成多媒体信息直接进行显示处理，所有副通道获取存储的所述合成多媒体信息，并对获取的合成多媒体信息进行显示处理；如此，各副通道通过直接获取经过合成处理得到的合成多媒体信息，使得各副通道在对合成多媒体信息进行显示处理前，无需执行对源多媒体信息进行合成的操作，节省了硬件资源，降低了硬件成本。
步骤104，各通道同步输出所述目标多媒体信息；
具体地，对主通道及所有副通道输出进行同步处理，使得各通道同步输出所述目标多媒体信息；
实现多通道同步输出目标多媒体信息的结构框架图，如图2所示，可以看出，多路复用器MUX将视频层数据、图形层数据和光标层数据进行合成，将合成后的数据发送至Main mixer进行Alpha混合处理；将混合处理后的数据一路发送至PPU进行显示处理，将混合处理后的数据另一路通过Write back机制回写至DDR；回写至DDR的数据可以直接发送至PPU进行显示处理，再通过Auxiliary显示接口进行显示。
