图1示出本申请实施例提供的一种多媒体数据的共享方法的流程示意图。该多媒体数据的共享方法可应用于媒体共享服务器。如图1所示，本申请实施例中的多媒体数据的共享方法可以包括步骤S101至S103。
步骤S101，获取多媒体数据的配置信息和共享方式。
多媒体数据的配置信息能够反应终端的需求信息，即终端期望获取到的多媒体数据的格式或类型等。共享方式表征多媒体数据在终端与当前的媒体共享服务器之间的传输方式。
通过获取多媒体数据的配置信息，能够反应不同的终端对不同类型的多媒体数据的需求信息，使媒体共享服务器能够更具针对性地 为不同的终端提供合适的多媒体数据，满足不同终端的个性化需求。
步骤S102，依据多媒体数据的配置信息对采集到的多媒体数据进行处理，获得支持多种输出格式的待共享数据。
多媒体数据可以是通过数据采集设备采集到的数据，例如，图像数据和/或视频数据等。
通过多媒体数据的配置信息，对图像数据和/或视频数据进行处理，能够获得不同传输格式或不同显示格式的待共享数据。例如，该待共享数据可以包括：对原始图像处理后的基于红绿蓝(Red Green Blue，RGB)色彩模式的数据(即RGB数据)、YUV数据、对原始视频数据处理后的剪辑视频文件和视频图像中的至少一种。
需要说明的是，RGB和YUV都是色彩空间，用于表示颜色。两者可以相互转化。YUV中的“Y”表示明亮度，即灰阶值；而“U”和“V”表示的则是影像色彩及饱和度，用于指定像素的颜色。RGB色彩模式是工业界的一种颜色标准，是通过对红(R)、绿(G)、蓝(B)三个颜色通道的变化以及它们相互之间的叠加来得到各式各样的颜色。
步骤S103，依据共享方式，共享待共享数据。
共享方式可以包括多种传输方式，或多种数据访问方式。
通过多种传输方式或多种数据访问方式，将待共享数据与多个终端或多个网络设备进行共享，能够使待共享数据被多个用户使用，扩大待共享数据的共享范围。
在本申请实施例提供的多媒体数据的共享方法中，通过获取多媒体数据的配置信息和共享方式，可明确终端所需的多媒体数据、以及该多媒体数据的共享方式，为终端准备适合的多媒体数据；依据多媒体数据的配置信息对采集到的多媒体数据进行处理，获得支持多种输出格式的待共享数据，避免数据的输出格式单一的问题，满足终端的个性化需求，提升用户的使用体验；以及通过多种共享方式，共享待共享数据，扩大待共享数据的共享范围。
本申请实施例还提供了一种实现方式，上述的共享方式包括：以接口的方式共享；步骤S103可采用如下方式实现：获取信令接口和数据管道的接口；以及依据信令接口和数据管道的接口，获取并共 享待共享数据。
数据管道是依据多媒体数据的类别确定的管道，信令接口是用于传输数据管道的配置信息的接口。
通过信令接口，能够获知数据管道具体适合传输的待共享数据的数据类型，在待共享数据的数据类型确定的情况下，采用与该数据类型对应的数据管道，传输该待共享数据，能够提升待共享数据的分享效率。
例如，接口可以包括：应用编程接口(Application Programming Interface，API)，和/或，高清晰度多媒体接口(High Definition Multimedia Interface，HDMI)。通过API和/或HDMI来分享待共享数据，可以提升待共享数据的分享速度，加快终端获取该待共享数据的速度，提升用户的使用体验。
在一些实施方式中，所述依据信令接口和数据管道的接口，获取并共享待共享数据包括：依据信令接口，获取数据管道的工作状态和数据管道的接口标识；以及在确定数据管道的工作状态为开启状态的情况下，依据数据管道的接口标识，获取并共享待共享数据。
数据管道的工作状态包括：开启状态或关闭状态。在确定数据管道的工作状态为开启状态的情况下，该数据管道可以用于传输待共享数据；在确定数据管道的工作状态为关闭状态的情况下，该数据管道不能传输待共享数据。
数据管道的接口标识与该数据管道能够传输的待共享数据的数据类型相关。例如，数据管道的接口标识为“A01”，则表示该数据管道可以传输数据类型为“A”的待共享数据，“01”表示数据管道的编号。
通过数据管道的工作状态和数据管道的接口标识，能够明确待共享数据进行传输具体所使用的数据管道，使不同数据类型的待共享数据都可以通过对应的数据管道进行共享，加快待共享数据的共享速度。
本申请实施例还提供了一种实现方式，上述的共享方式还包括：以内部组网的方式共享；步骤S103可采用如下方式实现：与至少一 个应用建立数据通道；以及使用数据通道，与应用共享待共享数据。

例如，应用可以与当前服务器之间建立基于套接字的通信连接，应用通过套接字发送数据请求消息，当前服务器通过套接字将数据响应消息反馈至应用，以实现应用与当前服务器之间的消息交互，进而完成待共享数据的共享。
通过与至少一个应用建立数据通道，使多个应用与当前服务器之间建立数据通信网络，在该数据通信网络内，使用数据通道，实现待共享数据的共享，使多个应用都能够获得当前服务器的数据服务，扩展了待共享数据的共享范围。
本申请实施例还提供了一种实现方式，上述的共享方式还包括：以共享内存的方式共享；步骤S103可采用如下方式实现：与应用进行数据同步；以及在确定数据同步完成的情况下，依据与应用相连接的共享内存，与应用共享待共享数据。

需要说明的是，应用和当前服务器只有先进行数据同步，才能使应用获取到的待共享数据与当前服务器发布的待共享数据保持一致，以避免待共享数据出现共享偏差，导致待共享数据的共享错误。
本申请实施例还提供了一种实现方式，上述的共享方式还包括：组群共享；步骤S103可采用如下方式实现：获取群组管理装置中的组群的数据需求信息；依据组群的数据需求信息，从待共享数据中选取与组群对应的定制数据；以及发送定制数据至群组管理装置，以供群组管理装置将定制数据共享给组群中的多个终端。
群组管理装置配置为构建多个组群，每个组群中的多个终端具 有相同的数据需求。
通过建立组群，使多个具有相同数据需求的终端能够通过组群实时获得待共享数据，提升待共享数据的分享速度。并且，组群能够使多个处于不同位置的终端同时获得待共享数据，减少了待共享数据的传输时延，不仅保证了待共享数据的准确性，还提升了待共享数据的传输速度。

多媒体数据的配置信息包括：编码方式。该编码方式可以包括：预测编码、变换编码、量化编码、子带编码和基于预设协议的编码中的至少一种。
上述预设协议可以包括：H.261协议、H.265协议和H.264协议中的至少一种。
步骤S202，对多媒体数据进行预处理，获得预处理数据。
对多媒体数据进行预处理可以是对原始的多媒体数据进行数据筛选，以确定多媒体数据的数据类型；还可以是对原始的多媒体数据进行排序，以确定多媒体数据的先后顺序；还可以是对原始的多媒体数据进行审核，以获得完整准确的多媒体数据等。以上对于对多媒体数据进行预处理的方式仅是举例说明，可根据实际需求进行具体设定，其他未说明的对多媒体数据进行预处理的方式也在本申请的保护范围之内，在此不再赘述。
步骤S203，依据编码方式对预处理数据进行编码，生成编码后的数据。

预测编码是根据离散信号之间存在着一定关联性的特点，利用前面一个或多个信号预测下一个信号；然后，对实际值和预测值之间的差(即预测误差)进行编码。如果预测值越趋近于实际值，则预测误差越小。在同等精度要求的条件下，可以用较少的比特进行编码，以实现数据的压缩。
变换编码是从频域的角度减小图像信号的空间相关性，在降低数码率等方面，可以获得和预测编码相近的效果。
量化是指将信号的连续取值近似为有限多个离散值，或，将大量可能的离散取值近似为较少的离散值的过程。而量化编码，能够实现对图像中的突出的物体进行定位的效果，以加快图像处理。
子带编码(Subband Coding，SBC)是一种以信号频谱为依据的编码方法，即将信号分解成不同频带分量来去除信号相关性，再将分量分别进行取样、量化、编码，从而得到一组互不相关的码字，然后将这些码字合并在一起，形成子带编码结果。因不同频带的量化噪声都被束缚在本频带内，可以避免能量较小的频带内的信号被其它频段中的量化噪声所掩盖，提升数据的准确性。
