相关申请的交叉引用
本申请基于申请号为201610940818.0、申请日为2016年10月31日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及信息切换技术，尤其涉及一种媒体信息的切换方法及服务器、计算机存储介质。
背景技术
随着网络技术和智能终端的发展，使得每一个用户都可以作为媒体信息的制作者和发布者，在直播的场景中，由于每一个用户都是独立和分散存在于在整个网络中的，则每一个用户所制作的直播节目(或称直播媒体信息)也具有独立性，直播节目(或称直播媒体信息)的制作和发布时间也具有独立性，因此，在多个直播节目(或称直播媒体信息)间进行切换是无法确保时效性和流畅性的，比如，后台服务器在多个直播节目(或称直播媒体信息)间进行切换时，在用户侧会出现直播中断等问题，更谈不上将多个直播节目(或称直播媒体信息)汇编成一套网络节目时需要耗费大量的时间成本和处理成本。
发明内容
有鉴于此，本发明实施例提供了一种媒体信息的切换方法及服务器、计算机存储介质，至少解决了现有技术存在的问题。
本发明实施例的技术方案是这样实现的：
本发明实施例的一种媒体信息的切换方法，所述方法包括：
接收至少一个媒体信息；
将所述至少一个媒体信息转换为与所述至少一个媒体信息对应的至少一路电信号；
获取切换请求，所述切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息；
响应所述切换请求，将与所述当前媒体信息对应的当前电信号切换为与所述目标媒体信息对应的目标电信号进行传输，在所述目标电信号传输至所述直播端播放前对所述目标电信号进行编码转换，以得到所述目标媒体信息，传输所述目标媒体信息至所述直播端进行播放。
本发明实施例的一种服务器，所述服务器包括：
接收单元，用于接收至少一个媒体信息；
转换单元，用于将所述至少一个媒体信息转换为与所述至少一个媒体信息对应的至少一路电信号；
获取单元，用于获取切换请求，所述切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息；
响应单元，用于响应所述切换请求，将与所述当前媒体信息对应的当前电信号切换为与所述目标媒体信息对应的目标电信号进行传输，在所述目标电信号传输至所述直播端播放前对所述目标电信号进行编码转换，以得到所述目标媒体信息，传输所述目标媒体信息至所述直播端进行播放。
本发明实施例的一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于上述方案任一项所述的媒体信息的切换方法。
本发明实施例的一种媒体信息的切换方法，应用于服务器，服务器包 括有一个或多个处理器以及存储器，以及一个或一个以上的程序，其中，所述一个或一个以上的程序存储于存储器中，所述程序可以包括一个或一个以上的每一个对应于一组指令的模块，所述一个或多个处理器被配置为执行指令；所述方法包括：
接收至少一个媒体信息；
将所述至少一个媒体信息转换为与所述至少一个媒体信息对应的至少一路电信号；
获取切换请求，所述切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息；
响应所述切换请求，将与所述当前媒体信息对应的当前电信号切换为与所述目标媒体信息对应的目标电信号进行传输，在所述目标电信号传输至所述直播端播放前对所述目标电信号进行编码转换，以得到所述目标媒体信息，传输所述目标媒体信息至所述直播端进行播放。
本发明实施例是将接收的至少一个媒体信息进行转换，以得到与所述至少一个媒体信息对应的至少一路电信号，由于电信号的传输时时延较低，且在直播切换时的瞬间间断，电信号可以瞬间恢复，因此，获取切换请求后，对切换请求进行响应，可以将与当前媒体信息对应的当前电信号切换为与目标媒体信息对应的目标电信号进行传输，以便减少传输时延，节约时间成本和处理成本，在直播端支持播放媒体类型的信息，从而在目标电信号传输至直播端播放前对该目标电信号进行编码转换，以得到播放媒体类型的信息，即重新得到目标媒体信息，传输目标媒体信息至直播端进行播放。采用本发明实施例，在多个直播节目(或称直播媒体信息)间进行切换时能确保时效性和播放流畅性。

具体实施方式
下面结合附图对技术方案的实施作进一步的详细描述。
现在将参考附图描述实现本发明各个实施例的移动终端。在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明实施例的说明，其本身并没有特定的意义。因此，"模块"与"部件"可以混合地使用。
在下面的详细说明中，陈述了众多的具体细节，以便彻底理解本发明。不过，对于本领域的普通技术人员来说，显然可在没有这些具体细节的情况下实践本发明。在其他情况下，没有详细说明公开的公知方法、过程、组件、电路和网络，以避免不必要地使实施例的各个方面模糊不清。
另外，本文中尽管多次采用术语“第一”、“第二”等来描述各种元件(或各种阈值或各种应用或各种指令或各种操作)等，不过这些元件(或阈值或应用或指令或操作)不应受这些术语的限制。这些术语只是用于区分一个元件(或阈值或应用或指令或操作)和另一个元件(或阈值或应用或指令或操作)。例如，第一操作可以被称为第二操作，第二操作也可以被 称为第一操作，而不脱离本发明的范围，第一操作和第二操作都是操作，只是二者并不是相同的操作而已。
本发明实施例中的步骤并不一定是按照所描述的步骤顺序进行处理，可以按照需求有选择的将步骤打乱重排，或者删除实施例中的步骤，或者增加实施例中的步骤，本发明实施例中的步骤描述只是可选的顺序组合，并不代表本发明实施例的所有步骤顺序组合，实施例中的步骤顺序不能认为是对本发明的限制。
本发明实施例中的术语“和/或”指的是包括相关联的列举项目中的一个或多个的任何和全部的可能组合。还要说明的是：当用在本说明书中时，“包括/包含”指定所陈述的特征、整数、步骤、操作、元件和/或组件的存在，但是不排除一个或多个其他特征、整数、步骤、操作、元件和/或组件和/或它们的组群的存在或添加。
本发明实施例的智能终端(如移动终端)可以以各种形式来实施。例如，本发明实施例中描述的移动终端可以包括诸如移动电话、智能电话、笔记本电脑、数字广播接收器、个人数字助理(PDA，Personal Digital Assistant)、平板电脑(PAD)、便携式多媒体播放器(PMP，Portable Media Player)、导航装置等等的移动终端以及诸如数字TV、台式计算机等等的固定终端。下面，假设终端是移动终端。然而，本领域技术人员将理解的是，除了特别用于移动目的的元件之外，根据本发明的实施方式的构造也能够应用于固定类型的终端。
图1为本发明实施例中进行信息交互的各方硬件实体的示意图，图1中包括：直播交互的第一端1、服务器2和直播交互的第二端3；其中，直播交互的第一端(如主播端)可以采用手机、台式机、PC机、一体机等类型的终端设备，如终端设备11-14所示，终端设备11-14通过有线网络或者无线网络与服务器进行信息交互。直播交互的第二端(如观众端)也可以 采用手机、台式机、PC机、一体机等类型的终端设备，本实施例中采用手机，如终端设备31-35所示。采用本发明实施例，在媒体直播场景中，对媒体信息(如视频信息)的切换，通过媒体信息(如视频信息)的接收，由媒体信息(如视频信息)到电信号的转换，将转换得到的电信号进行编码，以重新得到媒体信息(如视频信息)进行播放。其中，所述重新得到媒体信息(如视频信息)可以为从直播交互的第一端(如主播端)得到的最初的媒体信息(如原有视频信息)，如媒体信息A1-A2，也可以是有别于最初的媒体信息(如原有视频信息)的新媒体信息(如新视频信息)，比如，根据媒体信息A1-A2得到的多个媒体信息B1-B2，或者根据媒体信息A1-A2进行汇编得到的一个完整的媒体信息B。以服务器2为针对媒体直播场景中对媒体信息(如视频信息)进行切换响应的执行实体而言，服务器的处理逻辑10如图1所示，包括：S1、服务器将从多个直播交互的第一端(如主播端，主播端的用户可以是媒体信息的制作者和发布者)接收的至少一个媒体信息转换为与所述至少一个媒体信息对应的至少一路电信号(比如SDI电信号)。S2、获取切换请求，所述切换请求由直播交互的第二端(如观众端，观众端的用户可以是媒体信息的播放者)发起，所述切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息。S3、服务器响应所述切换请求，将与所述当前媒体信息对应的当前电信号切换为与所述目标媒体信息对应的目标电信号进行传输，在直播交互的第二端(如观众端，观众端的用户可以是媒体信息的播放者)支持播放的信息为媒体类型的信息，则在将目标电信号传输至直播端播放前对所述目标电信号进行编码转换，以得到可以在直播交互的第二端(如观众端，观众端的用户可以是媒体信息的播放者)播放的目标媒体信息，传输所述目标媒体信息至直播交互的第二端(如观众端，观众端的用户可以是媒体信息的播放者)，在直播交互的第二端(如观众端，观众端的用户可以是媒体信息的播放者)播放 目标媒体信息。所述目标媒体信息包括：从直播交互的第一端(如主播端，主播端的用户可以是媒体信息的制作者和发布者)直接接收的至少一个媒体信息，和/或根据该直接接收的至少一个媒体信息得到的、且有别于该直接接收的至少一个媒体信息的至少一个媒体信息，和/或根据该直接接收的至少一个媒体信息得到的一个汇编形式的媒体信息。
这里需要指出的是，处理逻辑10可以采用单元的形式存在于一个服务器，也可以采用多个硬件实体的形式分别于由多个服务器构成的服务器集群系统中。不管是某一个服务器中的单元形式，还是服务器集群系统中硬件实体的形式，本发明实施例中，针对切换请求的响应处理逻辑至少包括：1)从直播第一端接收媒体信息(具体如采集媒体信息)；2)将媒体信息切换为电信号(如SDI电信号)；对电信号(如SDI电信号)进行编码转换，以得到可以在直播第二端播放的媒体信息。
在直播的场景中，由于每一个用户都是独立和分散存在于在整个网络中的，则每一个用户所制作的直播节目(或称直播媒体信息)也具有独立性，直播节目(或称直播媒体信息)的制作和发布时间也具有独立性，因此，在多个直播节目(或称直播媒体信息)间进行切换是无法确保时效性和流畅性的，比如，后台服务器在多个直播节目(或称直播媒体信息)间进行切换时，在用户侧会出现直播中断等问题，更谈不上将多个直播节目(或称直播媒体信息)汇编成一套网络节目时需要耗费大量的时间成本和处理成本。采用本发明实施例，将接收的至少一个媒体信息进行转换，以得到与所述至少一个媒体信息对应的至少一路电信号，由于电信号的传输时时延较低，且在直播切换时的瞬间间断，电信号可以瞬间恢复，因此，获取切换请求后，对切换请求进行响应，可以将与当前媒体信息对应的当前电信号切换为与目标媒体信息对应的目标电信号进行传输，以便减少传输时延，节约时间成本和处理成本，在直播端支持播放媒体类型的信息， 从而在目标电信号传输至直播端播放前对该目标电信号进行编码转换，以得到播放媒体类型的信息，即重新得到目标媒体信息，传输目标媒体信息至直播端进行播放，在多个直播节目(或称直播媒体信息)间进行切换时能确保时效性和播放流畅性。
上述图1的例子只是实现本发明实施例的一个系统架构实例，本发明实施例并不限于上述图1所述的系统结构，基于上述图1所述的系统架构，提出本发明方法各个实施例。
本发明实施例的一种媒体信息的切换方法，如图2所示，所述方法包括：服务器接收至少一个媒体信息，将所述至少一个媒体信息转换为与所述至少一个媒体信息对应的至少一路电信号(101)。比如，媒体信息可以为网络视频流，将网络视频流转换为SDI电信号，由于网络视频流传输的是视频文件，如果在断流的再恢复的情况下，需要缓冲一定时间才能够播放当前文件，而SDI是电信号，是靠高低电平来发送一帧一帧的图像信号，因此，当传输SDI电信号时，如果瞬间间断，也可以瞬间即可恢复。且在SDI传输的情况下可以借助已有的广播电视技术，具有毫秒级的缓冲(buffer)处理的切换，能很好的满足切换时无缝衔接的需要。获取切换请求，所述切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息(102)。响应所述切换请求，将与所述当前媒体信息对应的当前电信号切换为与所述目标媒体信息对应的目标电信号进行传输，在所述目标电信号传输至所述直播端(具体为直播交互的第二端)播放前对所述目标电信号进行编码转换，以得到所述目标媒体信息，传输所述目标媒体信息至所述直播端进行播放(103)。比如，将网络视频流转换为SDI电信号传输，利用SDI电信号传输时时延较低的特性来改善现有切换过程中时延和处理效率低下的问题。以多个媒体信息中的一个媒体信息的转换进行举例，比如，初始的目标媒体信息为媒体信息A，对应目标电信号B(A)，传输目标 电信号B(A)，编码转换结果为媒体信息A，即重新得到目标媒体信息A，或者，基于媒体信息A得到的媒体信息A’。将目标媒体信息A或A’作为系统响应直播第二端(具体为直播交互的第二端)切换请求的反馈结果，即发送目标媒体信息A或A’给发起切换请求的直播第二端(具体为直播交互的第二端)，在直播第二端(具体为直播交互的第二端)播放该目标媒体信息A或A’。传输所述目标媒体信息至所述直播第二端(具体为直播交互的第二端)进行播放。
现有技术中，在传统的网络直播中，当个人网络直播或者手机直播在网络上已经开放入口时，只能允许这一个人直播，如果想要切换到另外一人直播的话，需要更改视频直播后台的视频流地址，这样就会使当前的直播瞬间断流，在用户端呈现出来的是瞬间黑屏，然后内容分发网络(CDN，Content Delivery Network)重新分发新的视频流，用户端等待漫长的重新缓冲。这样一次操作，会耗费大量时间，毫无流畅度可言，无法在直播场景中给用户侧带来良好的播放效果。
本发明实施例中，是针对多路间的任意切换，输出的切换结果经编码转换后得到的结果，为目标媒体信息。具体的，直播交互的第一端(如主播端)通过PC或者手机将直播的视频流发送到网络直播的服务后台服务器后，从后台服务器拿到直播的视频流，经过用于视频流到电信号转换的转换，得到SDI电信号，比如，将播放直播的视频流所采集到的图像信号和音频信号转换成SDI信号，通过无缝切换，对切换后的SDI电信号进行编码，以得到网络视频流形式的目标媒体信息，即：以网络视频流形式传输目标媒体信息到CDN，之后通过CDN分发给直播交互的第二端(如观众端)收看目标媒体信息。
本发明实施例的一种媒体信息的切换方法，如图3所示，所述方法包括：服务器接收至少一个媒体信息，播放所述至少一个媒体信息，输出至 少一个播放信号(201)。将得到的至少一个播放信号确定为与至少一个媒体信息对应的至少一路电信号(202)，以将所述至少一个媒体信息转换为与所述至少一个媒体信息对应的至少一路电信号。比如，媒体信息为直播的视频流时，获取在播放直播的视频流所采集到的播放信号(包括图像信号和音频信号)，根据图像信号和音频信号得到SDI信号，即通过该特殊的采集处理而转换得到该SDI信号。由于网络视频流传输的是视频文件，如果在断流的再恢复的情况下，需要缓冲一定时间才能够播放当前文件，而SDI是电信号，是靠高低电平来发送一帧一帧的图像信号，因此，当传输SDI电信号时，如果瞬间间断，也可以瞬间即可恢复。且在SDI传输的情况下可以借助已有的广播电视技术，具有毫秒级的buffer处理的切换，能很好的满足切换时无缝衔接的需要。获取切换请求，所述切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息(203)。响应所述切换请求，将与所述当前媒体信息对应的当前电信号切换为与所述目标媒体信息对应的目标电信号进行传输，针对所述目标电信号而言，如图4所示，是将与所述至少一个媒体信息对应的所述至少一路电信号组装成一路电信号，将该路电信号作为所述目标电信号进行传输(204)。在所述目标电信号传输至直播端(具体为直播交互的第二端)播放前对所述目标电信号进行编码转换，以得到所述目标媒体信息，传输所述目标媒体信息至所述直播端进行播放(205)。比如，将网络视频流转换为SDI电信号传输，利用SDI电信号传输时时延较低的特性来改善现有切换过程中时延和处理效率低下的问题。以多个媒体信息中的一个媒体信息的转换进行举例，比如，初始的目标媒体信息为媒体信息A，对应目标电信号B(A)，传输目标电信号B(A)，编码转换结果为媒体信息A，即重新得到目标媒体信息A，或者，基于媒体信息A得到的媒体信息A’。将目标媒体信息A或A’作为系统响应直播第二端(具体为直播交互的第二端)切换请求的反馈结果，即发送 目标媒体信息A或A’给发起切换请求的直播第二端(具体为直播交互的第二端)，在直播第二端(具体为直播交互的第二端)播放该目标媒体信息A或A’。传输所述目标媒体信息至所述直播第二端(具体为直播交互的第二端)进行播放。
现有技术中，在传统的网络直播中，当个人网络直播或者手机直播在网络上已经开放入口时，只能允许这一个人直播，如果想要切换到另外一人直播的话，需要更改视频直播后台的视频流地址，这样就会使当前的直播瞬间断流，在用户端呈现出来的是瞬间黑屏，然后CDN重新分发新的视频流，用户端等待漫长的重新缓冲。这样一次操作，会耗费大量时间，毫无流畅度可言，无法在直播场景中给用户侧带来良好的播放效果。而且，由于现有的操作，会耗费大量时间，毫无流畅度可言，因此，将任何有序的节目筹备汇编成一套网络节目更是无从实现，所以在传统网络直播中，是无法实现将个人网络直播汇集成一套网络节目的。
本发明实施例中，是将多路电信号组装为一路电信号，输出的组装结果(该路电信号)经编码转换后得到的结果，为所述目标媒体信息。具体的，直播交互的第一端(如主播端)通过PC或者手机将直播的视频流发送到网络直播的服务后台服务器后，从后台服务器拿到直播的视频流，经过用于视频流到电信号转换的转换，得到SDI电信号，比如，将播放直播的视频流所采集到的图像信号和音频信号转换成SDI信号，通过无缝切换，可以将每个用户个体直播的内容汇集到本服务器进行集中切换，最终可以汇集成一套网络节目。对切换后的SDI电信号进行编码，以得到网络视频流形式的目标媒体信息，即：以网络视频流形式传输目标媒体信息到CDN，之后通过CDN分发给直播交互的第二端(如观众端)收看目标媒体信息。这里需要指出的是，对汇集成一套节目而言，该目标媒体信息甚至和综艺、体育等节目进行融合，实现个人直播融入到综艺、体育等节目制作中，以 增添节目的多元化内容，也就是说，本发明实施例不仅仅是手机和PC的直播之间的切换制作，更可以将手机、PC、摄像机、录像机等多个内容进行混合制作，以得到一套多元化内容的网络节目，实现多个网络个人直播的汇集编排，制作成网络节目并提供给用户进行播放。
基于上述各个实施例，在本发明实施例一实施方式中，所述方法还包括：将与所述至少一个媒体信息对应的所述至少一路电信号组装成一路电信号并作为所述目标电信号进行传输。
基于上述各个实施例，在本发明实施例一实施方式中，所述方法还包括：从所述至少一路电信号的每一路电信号中，提取出第一图像信号和第一音频信号，并分别传输所述第一图像信号和所述第一音频信号，如后续提及的解嵌处理。对所述第一音频信号按照预设策略进行音频处理，以得到第二音频信号。比如，根据所述第二音频信号和所述第一图像信号进行音视频同步处理后重新合成所述每一路电信号，如后续提及的加嵌处理。
对所述第一音频信号按照预设策略进行音频处理，以得到第二音频信号，具体包括：1)获取所述预设策略，所述预设策略为调音的音频处理时，对所述第一音频信号进行调音后得到所述第二音频信号；2)获取所述预设策略，所述预设策略为混音的音频处理时，对所述第一音频信号进行混音后得到所述第二音频信号。
基于上述各个实施例，处理逻辑至少包括：1)从直播第一端接收媒体信息(具体如采集媒体信息)；2)将媒体信息切换为电信号(如SDI电信号)；对电信号(如SDI电信号)进行编码转换，以得到可以在直播第二端播放的媒体信息。
针对该处理逻辑，在一个实际应用为例，对采集、切换包装、编码(如将制作完成的SDI信号重新编码成网络视频流，然后传输到CDN并分发给 用户侧)进行具体阐述。
一，采集阶段：手机或者PC将拍摄的画面通过网络传输到直播服务平台后台，然后通过视频流VID，从后台将视频流拉取到网络采集设备中播放，这样就可以在网络采集设备的画面中呈现直播画面和音频，再将直播画面和音频信号输出并转换成SDI信号。
二，切换阶段：将从采集信号那里传过来的SDI信号进行切换，由于一般广播电视级切换台都会消除嵌入在SDI里的音频，所以，在进行切换之前需要先进行解嵌，即将音频从SDI中解嵌出来，然后进行调音处理。调音处理包括调节声音电平和混音等处理，最后，将输出的图像信号和音频信号进行视音频同步调节后进行加嵌，即将音频信号嵌入到SDI信号中。
三，编码阶段：将制作完成的SDI信号重新编码成网络视频流，然后推送到CDN并分发出去。
本发明实施例的一种媒体信息切换系统，如图5所示，包括：直播端和服务器端，直播端分为直播交互的第一端(如主播端)41和直播交互的第二端(如观众端)42。其中，在直播交互的第一端(如主播端)41，其用户可以是媒体信息的制作者和发布者，用于上传媒体信息到服务器；而直播交互的第二端(如观众端)42，其用户可以是媒体信息的播放者，用于发起切换请求，切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息，接收服务器对该切换请求响应后得到的反馈结果，所述反馈结果为所请求的目标媒体信息。服务器43，用于将从直播交互的第一端(如主播端)接收的媒体信息(如视频信息)转换到电信号，将转换得到的电信号进行编码，以重新得到媒体信息(如视频信息)进行播放。其中，所述重新得到媒体信息(如视频信息)可以为从直播交互的第一端(如主播端)得到的最初的媒体信息(如原有视频信息)，如媒体信息A1-A2，也可以是有别于最初的媒体信息(如原有视频信息)的新媒体信息(如新视频 信息)，比如，根据媒体信息A1-A2得到的多个媒体信息B1-B2，或者根据媒体信息A1-A2进行汇编得到的一个完整的媒体信息B。
服务器43包括：接收单元431，用于接收至少一个媒体信息；转换单元432，用于将所述至少一个媒体信息转换为与所述至少一个媒体信息对应的至少一路电信号；获取单元433，用于获取切换请求，所述切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息；响应单元434，用于响应所述切换请求，将与所述当前媒体信息对应的当前电信号切换为与所述目标媒体信息对应的目标电信号进行传输，在所述目标电信号传输至所述直播端播放前对所述目标电信号进行编码转换，以得到所述目标媒体信息，传输所述目标媒体信息至所述直播端进行播放。
具体的，服务器接收至少一个媒体信息，将所述至少一个媒体信息转换为与所述至少一个媒体信息对应的至少一路电信号。比如，媒体信息可以为网络视频流，将网络视频流转换为SDI电信号，由于网络视频流传输的是视频文件，如果在断流的再恢复的情况下，需要缓冲一定时间才能够播放当前文件，而SDI是电信号，是靠高低电平来发送一帧一帧的图像信号，因此，当传输SDI电信号时，如果瞬间间断，也可以瞬间即可恢复。且在SDI传输的情况下可以借助已有的广播电视技术，具有毫秒级的buffer处理的切换，能很好的满足切换时无缝衔接的需要。获取切换请求，所述切换请求用于将在直播端播放的当前媒体信息切换为目标媒体信息。响应所述切换请求，将与所述当前媒体信息对应的当前电信号切换为与所述目标媒体信息对应的目标电信号进行传输，在所述目标电信号传输至直播端(具体为直播交互的第二端)播放前对所述目标电信号进行编码转换，以得到所述目标媒体信息，传输所述目标媒体信息至所述直播端进行播放。比如，将网络视频流转换为SDI电信号传输，利用SDI电信号传输时时延较低的特性来改善现有切换过程中时延和处理效率低下的问题。以多个媒 体信息中的一个媒体信息的转换进行举例，比如，初始的目标媒体信息为媒体信息A，对应目标电信号B(A)，传输目标电信号B(A)，编码转换结果为媒体信息A，即重新得到目标媒体信息A，或者，基于媒体信息A得到的媒体信息A’。将目标媒体信息A或A’作为系统响应直播第二端(具体为直播交互的第二端)切换请求的反馈结果，即发送目标媒体信息A或A’给发起切换请求的直播第二端(具体为直播交互的第二端)，在直播第二端(具体为直播交互的第二端)播放该目标媒体信息A或A’。传输所述目标媒体信息至所述直播第二端(具体为直播交互的第二端)进行播放。
现有技术中，在传统的网络直播中，当个人网络直播或者手机直播在网络上已经开放入口时，只能允许这一个人直播，如果想要切换到另外一人直播的话，需要更改视频直播后台的视频流地址，这样就会使当前的直播瞬间断流，在用户端呈现出来的是瞬间黑屏，然后CDN重新分发新的视频流，用户端等待漫长的重新缓冲。这样一次操作，会耗费大量时间，毫无流畅度可言，无法在直播场景中给用户侧带来良好的播放效果。
本发明实施例中，是针对多路间的任意切换，输出的切换结果经编码转换后得到的结果，为目标媒体信息。具体的，直播交互的第一端(如主播端)通过PC或者手机将直播的视频流发送到网络直播的服务后台服务器后，从后台服务器拿到直播的视频流，经过用于视频流到电信号转换的转换，得到SDI电信号，比如，将播放直播的视频流所采集到的图像信号和音频信号转换成SDI信号，通过无缝切换，对切换后的SDI电信号进行编码，以得到网络视频流形式的目标媒体信息，即：以网络视频流形式传输目标媒体信息到CDN，之后通过CDN分发给直播交互的第二端(如观众端)收看目标媒体信息。
在本发明实施例一实施方式中，所述转换单元，进一步用于：采集所述至少一个媒体信息；播放所述至少一个媒体信息，输出至少一个播放信 号；将得到的所述至少一个播放信号确定为与所述至少一个媒体信息对应的至少一路电信号。
在本发明实施例一实施方式中，所述服务器还包括组装单元，用于：将与所述至少一个媒体信息对应的所述至少一路电信号组装成一路电信号并作为所述目标电信号进行传输。
在本发明实施例一实施方式中，所述服务器还包括：信号提取单元，用于从所述至少一路电信号的每一路电信号中，提取出第一图像信号和第一音频信号，并分别传输所述第一图像信号和所述第一音频信号；信号处理单元，用于对所述第一音频信号按照预设策略进行音频处理后，得到第二音频信号；信号合成单元，用于根据所述第二音频信号和所述第一图像信号重新合成所述每一路电信号。
在本发明实施例一实施方式中，所述信号处理单元，进一步用于：获取所述预设策略，所述预设策略为调音的音频处理时，对所述第一音频信号进行调音后得到所述第二音频信号。
在本发明实施例一实施方式中，所述信号处理单元，进一步用于：获取所述预设策略，所述预设策略为混音的音频处理时，对所述第一音频信号进行混音后得到所述第二音频信号。
其中，对于用于数据处理的处理器而言，在执行处理时，可以采用微处理器、中央处理器(CPU，Central Processing Unit)、数字信号处理器(DSP，Digital Singnal Processor)或可编程逻辑阵列(FPGA，Field－Programmable Gate Array)实现；对于存储介质来说，包含操作指令，该操作指令可以为计算机可执行代码，通过所述操作指令来实现上述本发明实施例信息处理方法流程中的各个步骤。
这里需要指出的是：以上涉及终端和服务器项的描述，与上述方法描述是类似的，同方法的有益效果描述，不做赘述。对于本发明终端和服务 器实施例中未披露的技术细节，请参照本发明方法流程描述的实施例所描述内容。
以一个现实应用场景为例对本发明实施例阐述如下：
在直播场景中，近两年由于个人直播、网络手机直播兴起，个人网络直播越来越普遍，可以展现生活中的个体差异，而这些直播一直都是单独个体直播节目，无法实现在同一时间汇集、展现给观众。具体的，在传统的网络直播中，当个人网络直播或者手机直播在网络上已经开放入口时，只能允许这一个人直播，如果想要切换到另外一人直播的话，需要更改视频直播后台的视频流地址，这样就会使当前的直播瞬间断流，在用户端呈现出来的是瞬间黑屏，然后CDN重新分发新的视频流到用户端进行实时播放。用户端等待漫长的重新缓冲。这样一次操作，会耗费大量时间，毫无流畅度可言，无法在直播中给客户良好体验，更别提将任何有序的节目筹备汇编成一套网络节目，在传统网络直播中，是无法实现将个人网络直播汇集成一套网络节目，这种新的节目制作播出模式呈现给用户的。
综上所述，以往的网络直播，需要手机或者PC通过摄像头采集，然后软件编码成网络视频流，通过互联网传输到网络视频服务平台，然后才通过平台接入、分发出去，各用户端可以看到直播者的直播画面，这时如果想要更换为另一个地点的直播者换面，就需要在后台更改直播流地址，导致正在直播的视频换面会中断，这是因为更改直播流地址时，中断了之前的直播视频流文件。之后，新的直播流接入后需要重新由用户端提请求，然后从CDN处分发，用户端需要识别缓冲，这都会耗费大量时间，而且毫无连贯性可言，也无法实现将个人网络直播汇集成一套网络节目播出。想要将个人网络直播汇集成一套网络节目播出，需要满足：1)多个视频源源按流程采集、接入直播系统；2)各个视频源之间平滑切换；3)视频源信号为了适应不同系统，不断变换传输形式。
基于上述分析，对于直播场景中的媒体信息切换及媒体信息汇编而言，采用本发明实施例，将一个个个体直播汇集到一点，进行集中切换，汇集成一套节目，甚至和综艺、体育等节目进行融合，实现个人直播融入到综艺、体育等节目制作中，增添节目多元化内容。具体的，直播者通过PC或者手机将直播发送到网络直播服务后台，从后台拿到直播流，经过用于转换的特殊采集，将采集到的信号转换成SDI信号进入切换设备，通过切换设备实现无缝切换，将切换之后的SDI的信号送入编码机进行编码，以网络视频流的方式传输到CDN，之后分发出去。这样就可以实现多个网络个人直播的汇集编排，制作成节目播放给用户。本发明实施例适用于网络视频直播、手机直播及传统广播电视直播，特别是直播中需要频繁切换网络视频源，而视频源来自于网络流或者手机统的情况。
如图6所示，为采用本发明实施例的一种手机网络直播流后端切换系统，在图6所示的系统整体架构中，可以分为：采集、切换包装、编码三个处理逻辑，以下对各个处理逻辑分别阐述。
(1)采集阶段：手机或者PC将拍摄的画面通过网络传输到直播服务平台后台，然后通过网络视频流对应的标识VID，从后台将视频流拉取到网络采集设备中播放，这样就可以在采集设备的画面中呈现直播画面和音频，再将画面和音频信号输出并转换成SDI信号，如图7所示。由于网络视频流传输的是视频文件，如果在断流的再恢复的情况下，需要缓冲一定时间才能够播放当前文件，而SDI是电信号，靠高低电平来发送一帧一帧的图像信号，如果瞬间间断，瞬间即可恢复，因此，需要先将网络视频流转换为SDI这种电信号后再进行传输。SDI传输的情况下可以借助已有的广播电视技术，切换台具有毫秒级的buffer，以满足切换时的无缝衔接需要。
(2)切换阶段：从采集信号那里传过来的SDI信号进入切换台，由于一般广播电视级切换台都会消除嵌入在SDI里的音频，所以，在进入切换 台之前先用解嵌器将音频解嵌出来，然后输入到调音台当中。如广播电视系统一样，切换台可以做各种划向、3D、飞入等平滑切换，而通过切换台可以实现包装、字母等功能。而调音台可以调节声音电平，混音等制作。之后输出的视音频调节同步后进入加嵌器，嵌入到SDI信号中，如图8所示。将网络视频流转化为SDI信号之后，还需要经过切换台和调音台等制作，是为了解决网络视频流不能够平滑切换视频的问题。通过此途径可以平滑切换网络视频源，以实现手机或PC信号的接入或切换，及远距离手机或PC拍摄的网络视频流传输入切换台和调音台后无论是切换还是汇编成一套自定义的网络节目都成为可能，为后续直播业务的发展提供了扩展空间。
(3)编码阶段：这一阶段较为简单，就是将制作完成的SDI信号重新编码成网络视频流，然后推倒CDN分发出去，如图9所示。
