本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例提供一种云终端与移动终端间的多媒体共享方法。
参见图1，图1为本发明云终端与移动终端间的多媒体共享方法第一实施例的流程示意图。
在第一实施例中，云终端与移动终端间的多媒体共享方法，包括：
步骤S10，云终端对向其发起连接的移动终端进行鉴权，将鉴权后的内容共享权限结果和远程操作权限结果发送给移动终端；
移动终端预分配远程操作权限的专用标识，云终端具有识别移动终端携带的专用标识的认证机构，当移动终端向云终端发起连接请求时，云终端对移动终端的专用标识进行鉴权。
第一步，云终端对向其发起连接的移动终端的内容共享权限进行判断，若鉴权成功，云终端则将鉴权后具有内容共享权限标识的结果发送给移动终端；若鉴权失败，云终端则将鉴权后不具有内容共享权限标识的结果发送给移动终端。
第二步，云终端对向其发起连接的移动终端的远程操作权限进行判断，若鉴权成功，云终端则将鉴权后具有远程操作权限标识的结果发送给移动终端；若鉴权失败，云终端则将鉴权后不具有远程操作权限标识的结果发送给移动终端。
步骤S20，云终端对共享内容进行采集，对采集的共享内容进行编码压缩；
如已经有一个或者多个移动终端和云终端建立连接，云终端对共享内容进行采集，共享内容包括：需要共享显示的屏幕内容、需要输出的视频和音频。如没有移动终端和云终端相连接，则云终端停止对局域网内共享内容的采集。
云终端采集完共享内容后，对采集的共享内容进行编码压缩，其中，编码压缩的方法有很多，主要分成以下四大类：(1)象素编码，编码时对每个象素单独处理，不考虑象素之间的相关性；(2)预测编码，编码时去除相邻象素之间的相关性和冗余性，只对新的信息进行编码；(3)变换编码，编码时将给定的图象变换到另一个数据域(如频域)上，使得大量的信息能用较少的数据来表示，从而达到压缩的目的；(4)其它方法，如混合编码(Hybird Coding)和矢量量化(Vector Quantize，VQ)。
步骤S30，云终端向有内容共享权限的移动终端多播编码压缩后的共享内容，供接收终端对接收到的共享内容进行解码解压并使用。
云终端将共享内容压缩编码后，向局域网内有内容共享权限的移动终端多播压缩编码后的共享内容，接收终端对共享内容进行解码解压，然后进行播放和使用。若移动终端一定时间内(例如，一分钟)没有接收到云
终端多播的共享内容，而又能监听到云终端广播的准备就绪信息，则移动终端重新向云终端发送请求建立连接；若移动终端一定时间内(例如，一分钟)既没有接收到云终端多播的共享内容，也没监听到云终端广播的准备就绪信息，移动终端则断开连接，并提示用户请检查网络连接是否正常，或者检查多媒体共享的客户端程序是否安装成功。
在本实施例中，通过对向云终端发起连接的移动终端进行鉴权，将鉴权后的内容共享权限结果和远程操作权限结果发送给移动终端；对共享内容进行采集；并对采集的共享内容进行编码压缩；最后云终端将压缩编码后的共享内容向有内容共享权限的移动终端多播，接收终端对接收到的共享内容进行解码解压并使用；从而移动终端可以清晰地播放云终端显示的内容，无需搭建专业化的云平台，技术要求不高、运营成低，同时，有远程操作权限的移动终端可以接入到多媒体共享的局域网中，既提高了多媒体共享的安全性和保密性，也实现了数量较多的移动终端同时进行多媒体共享。
参见图2，图2为本发明云终端与移动终端间的多媒体共享方法第二实施例的流程示意图。
在本发明第一实施例中，上述步骤S10之前还包括：
步骤S101，云终端向局域网内的移动终端定时广播共享服务信息；
云终端获得IP地址，以无线或有线方式接入为多媒体共享搭建的局域网，并运行多媒体共享的服务端程序，向局域网内广播多媒体共享服务信息，该共享服务信息包括云终端的身份信息、IP地址、运行状态等。
步骤S102，云终端接收移动终端在接收到共享服务信息后发送的连接请求，向移动终端单播连接响应；
若移动终端收到云终端广播的共享服务信息，则向云终端发起连接请求；当移动终端收到多个云终端广播的共享服务信息时，用户控制移动终端选择一个云终端，并向该云终端发起连接请求；云终端收到移动终端发
起的连接请求后，向移动终端单播连接响应。
步骤S103，云终端接收到移动终端发送的连接确认消息后，建立与移动终端之间的连接；连接确认消息为移动终端接收到单播的连接响应而发送。
若移动终端接收到云终端反馈的连接响应，则单播返回云终端连接确认信息，并且云终端和移动终端正式建立连接；若移动终端经过若干次(例如，三次)尝试，仍然无法与云终端建立连接时，移动终端则提供相关提示，并根据用户的选择进行退出共享或者继续请求服务。
参见图3，图3为本发明云终端与移动终端间的多媒体共享方法第三实施例的流程示意图。
在本发明的第二实施例中，上述步骤S101之后、步骤S102之前还包括：
步骤S104，云终端收到移动终端因未收到共享服务信息而广播的发起请求后，向移动终端单播共享服务信息；
移动终端以无线或有线方式接入与云终端所在的同一局域网，获取IP地址，运行多媒体共享的客户端程序，若一定时间内(例如，一分钟)没有收到任何云终端广播的共享服务信息，则向局域网内广播发现请求，发现请求中包括移动终端的身份信息、IP地址、运行状态等，以便于云终端收到发现请求后，向移动终端单播共享信息。
在本实施例中，通过云终端向局域网内定时广播共享服务信息；云终端收到移动终端因未收到共享服务信息而广播的发起请求后，向移动终端单播共享服务信息；云终端收到移动终端因收到共享服务信息而发送的连接请求后，向移动终端单播连接响应；云终端收到移动终端因收到连接响应而发送的连接确认后，建立与移动终端之间的连接，使得云终端与移动终端建立连接的过程更加清晰、更易于实现，同时使云终端与移动终端之间建立的连接关系更加稳定。
参见图4，图4为本发明云终端与移动终端间的多媒体共享方法第四实施例的流程示意图。
在上述第二实施例的基础上，在执行步骤30之后，本发明云终端与移动终端间的多媒体共享方法还包括：
步骤S40，云终端接收具有远程操作权限的移动终端发送的操作事件，对操作事件作出相应的多媒体响应，并将多媒体响应广播至局域网内的移动终端。
云终端对移动终端的远程操作标识进行权限判定，若移动终端具备远程操作权限，则当移动终端用户向云终端发起远程控制请求时，云终端同意移动终端的远程操作请求，然后移动终端可以把本地的操作事件发送回云终端，云终端对这些操作事件进行处理和分析后，在云终端进行相应响应和显示；若移动终端不具备远程操作权限，则当移动终端用户向云终端发起远程控制请求时，云终端拒绝移动终端的远程操作请求，并反馈移动终端相关请求失败的原因。
操作事件包括鼠标事件、键盘事件，及触屏事件。移动终端通过鼠标操作、键盘操作和触屏操作，从而形成鼠标事件、键盘事件和触屏事件，移动终端将各种操作事件发送给云终端，这样，提高了移动终端对云终端继续远程操作控制的多样性。
在本实施中，云终端接收具有远程操作权限的移动终端发送的操作事件并作出相应处理，云终端能够根据远程操作控制权限允许特定的移动终端对云终端进行远程操作，从而避免了无关移动终端操作对云终端的干扰，提高了多媒体共享过程的流畅性。

移动终端预分配远程操作权限的专用标识，鉴权模块50具有识别移动终端携带的专用标识的认证机构，当移动终端向云终端发起连接请求时，鉴权模块50对移动终端的专用标识进行鉴权。
第一步，鉴权模块50对向其发起连接的移动终端的内容共享权限进行判断，若鉴权成功，鉴权模块50则将鉴权后具有内容共享权限标识的结果发送给移动终端；若鉴权失败，鉴权模块50则将鉴权后不具有内容共享权限标识的结果发送给移动终端。
第二步，鉴权模块50端对向其发起连接的移动终端的远程操作权限进行判断，若鉴权成功，鉴权模块50则将鉴权后具有远程操作权限标识的结果发送给移动终端；若鉴权失败，鉴权模块50则将鉴权后不具有远程操作权限标识的结果发送给移动终端。
如已经有一个或者多个移动终端和云终端建立连接，采集编码模块60则对共享内容进行采集，共享内容包括：需要共享显示的屏幕内容、需要输出的视频和音频。如没有移动终端和云终端相连接，则采集编码模块60停止对局域网内共享内容的采集。
云终端采集完共享内容后，采集编码模块60对采集的共享内容进行编码压缩，其中，编码压缩的方法有很多，主要分成以下四大类：(1)象素编码，编码时对每个象素单独处理，不考虑象素之间的相关性；(2)预测编码，编码时去除相邻象素之间的相关性和冗余性，只对新的信息进行编码；(3)变换编码，编码时将给定的图象变换到另一个数据域(如频域)
上，使得大量的信息能用较少的数据来表示，从而达到压缩的目的；(4)其它方法，如混合编码(Hybird Coding)和矢量量化(Vector Quantize，VQ)。
采集编码模块60将共享内容压缩编码后，内容多播模块70向局域网内内有内容共享权限的移动终端多播压缩编码后的共享内容，接收终端对共享内容进行解码解压，然后进行播放和使用。若移动终端一定时间内(例如，一分钟)没有接收到内容多播模块70多播的共享内容，而又能监听到云终端广播的准备就绪信息，则移动终端重新向云终端发送请求建立连接；若移动终端一定时间内(例如，一分钟)既没有接收到采集编码模块60多播的共享内容，也没监听到云终端广播的准备就绪信息，移动终端则断开连接，并提示用户请检查网络连接是否正常，或者检查多媒体共享的客户端程序是否安装成功。
在本实施例中，通过采集编码模块60对共享内容进行采集并对采集的共享内容进行编码压缩；最后内容多播模块70将压缩编码后的共享内容向有内容共享权限的移动终端多播，接收终端对接收到的共享内容进行解码解压并使用；从而移动终端可以清晰地播放云终端显示的内容，无需搭建专业化的云平台，技术要求不高、运营成低，并且有远程操作权限的移动终端可以接入到多媒体共享的局域网中，可以实现数量较多的有权限的移动终端进行多媒体共享。
