Description

一种媒体处理方法、设备及系统
本申请要求于2013年12月25日提交中国专利局、申请号为201310729245.3、发明名称为“一种媒体处理方法、设备及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及媒体处理技术领域，尤其涉及一种媒体处理方法、设备及系统。
背景技术
随着数字媒体内容的高清化，包括高清/超高清视频格式(720p，1080p，4K，8K)和三维(Three Dimensions，3D)、高质量/无损音频格式等的普及，市场上出现了越来越多的新型有线和无线高清音视频传输技术和接口标准，例如高清晰度多媒体接口(High-Definition Multimedia Interface，HDMI)、显示接口(DisplayPort)、数字高清互动视音接口(Digital Interface for Video and Audio，DiiVA)、HDBaseT、移动高清连接(Mobile High-Definition Link，MHL)、Thunderbolt等有线技术以及无线千兆比特(Wireless Gigabit，WiGig)、无线家庭数字接口(Wireless Home Digital Interface，WHDI)、WirelessHD、802.11n/ac等无线技术用于各类家庭数字影音设备(高清/3D电视机、数字多功能光盘(Digital Versatile Disc，DVD)/蓝光播放机、高清机顶盒、投影仪、高保真(High-Fidelity，Hi-Fi)音响等)。
随着移动设备(手机、平板电脑等)的普遍智能化，移动设备也逐步参与到家庭网络音视频生态环境中，通用即插即用协议(Universal Plug and Play，UPnP)、数字生活网络联盟(Digital Living Network Alliance，DLNA)协议、闪联智能分组和资源共享(Intelligent Grouping And Resource Sharing，IGRS)协议、AirPlay、Miracast(Wi-Fi Display)、Wi-Di等技术使得手机和家庭数字影音设备 之间可以通过无线高保真(Wireless Fidelity，Wi-Fi)共享媒体数据，也可以通过蓝牙(Bluetooth，BT)共享媒体数据。有些家庭数字影音设备虽支持MHL、HDMI等技术，但插线对于用户来说还是不够方便，因而用户更倾向于使用Wi-Fi或者BT与家庭数字影音设备进行互动。因此市场上出现了一些适配设备(Adaptor)，比较常见的为Wi-Fi/BT转HDMI的小型转换器，通过Wi-Fi接收手机上的音视频内容，在转换器上解码后通过HDMI输出给电视、投影仪等显示设备；此外，有些还支持通过BT接收移动设备上的控制信号并转换成HDMI的控制信号，实现对显示设备的控制例如节目切换、音量调整等。
但目前的适配设备有一定局限性，主要体现在只有一个HDMI接口，一次只能接一台显示设备，用户若切换显示设备则需要重新插拔适配器。

具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
请参阅图1，为本发明实施例提供的一种媒体处理方法的流程示意图。该方法包括以下步骤：
步骤S101，媒体处理设备确定至少一种第一通信协议，以及获取至少一个媒体播放设备的媒体处理能力和支持的第二通信协议。
本发明实施例的媒体处理设备与媒体源设备通信，将从媒体源设备获取的或通过媒体源设备获取的待播放的媒体数据发送给媒体播放设备。在本步骤中，媒体处理设备确定一种或多种第一通信协议，此第一通信协议为媒体处理设备与媒体源设备之间的通信协议，媒体处理设备与一个或多个媒体播放设备通信，获取该一个或多个媒体播放设备的媒体处理能力和支持的第二通信协议，媒体处理设备与一个或多个媒体播放设备之间的通信协议为该第二通信协议。该媒体处理能力即媒体播放设备的播放能力，可以为支持的媒体格式(例如，H.264、H.265、mp3、JPEG等)、支持的媒体类型(例如，视频、音频、音视频、图像)，支持的视频分辨率(例如，720p、1080p、4K、8K等)，支持的像素深度(例 如，30比特/像素、36比特/像素、48比特/像素等)，支持的视频帧率(例如，24Hz、50Hz、60Hz等)，是否支持三维(Three Dimensions，3D)，支持的音频采样率(例如，32kHz、44.1kHz、48kHz等)等的任意一个或多个。
该第一通信协议包括蓝牙协议、通用即插即用协议、数字生活网络联盟协议、智能分组和资源共享协议、AirPlay协议(苹果公司制定的无线通讯技术)、无线高保真显示协议中的任意一种。
该媒体播放设备可以是计算机、电视机、播放器等，该第二通信协议包括高清晰度多媒体接口协议、显示接口协议、数字高清互动视音接口协议、HDBaseT协议、移动高清连接协议、Thunderbolt协议、无线千兆比特协议、无线家庭数字接口协议、WirelessHD协议中的任意一种。
步骤S102，所述媒体处理设备为每种所述第一通信协议构建具有所述至少一个媒体播放设备的媒体处理能力的至少一个媒体接收客户端，并通过所述第一通信协议对应的网络接口将所述至少一个媒体接收客户端的信息发送给媒体源设备。
该媒体处理设备针对每种第一通信协议构建一个或多个媒体接收客户端，该媒体接收客户端具有前述一个或多个媒体播放设备的媒体处理能力，然后，媒体处理设备通过每个第一通信协议对应的网络接口，将构建的与该第一通信协议对应的媒体接收客户端的信息发送给媒体源设备，该媒体接收客户端的信息包括媒体接收客户端的名称和/或图标、媒体处理能力等。
该媒体源设备可以是手机、平板电脑等终端设备。
步骤S103，所述媒体处理设备接收媒体源设备发送的由所述媒体源设备指定的媒体接收客户端进行播放的待播放的媒体数据。
媒体源设备在获取了媒体接收客户端的信息后，在媒体源设备上显示媒体 接收客户端的名称和/或图标，可以将待播放的媒体数据与媒体接收客户端的媒体处理能力进行匹配，从而确定播放该待播放的媒体数据的媒体接收客户端，当然，这里的播放并不是实际由该媒体接收客户端进行播放，而是由具有实际的与该媒体接收客户端对应的媒体处理能力的媒体播放设备进行播放；也可以由用户在媒体源设备上操作，指定媒体接收客户端。该待播放的媒体数据可以是可以直接播放的媒体数据，也可以是获取可播放的媒体数据的地址。媒体源设备将待播放的媒体数据及媒体接收客户端的指定信息发送给媒体处理设备。
媒体处理设备接收该待播放的媒体数据及媒体接收客户端的指定信息。
步骤S104，所述媒体处理设备将所述待播放的媒体数据通过所述指定的媒体接收客户端对应的第二通信协议发送给所述指定的媒体接收客户端对应的媒体播放设备进行播放。
由于构建的媒体接收客户端对应一个或多个媒体播放设备，各媒体播放设备与媒体处理设备通过第二通信协议通信，该第二通信协议可以为一种或多种，媒体处理设备将接收到的待播放的媒体数据通过第二通信协议发送给指定的媒体接收客户端对应的媒体播放设备进行播放。
在本实施例中，多个媒体播放设备与媒体处理设备连接，媒体源设备可以对应多个媒体接收客户端，每个媒体接收客户端具有相应的媒体处理能力，媒体源设备只需根据待播放的媒体数据与媒体接收客户端的媒体处理能力进行匹配或根据用户的操作指示，指定进行播放的媒体接收客户端，媒体处理设备接收到待播放的媒体数据后即可发送给指定的媒体接收客户端对应的媒体播放设备，由于媒体源设备对应的是虚拟构建的媒体接收客户端，可以随意切换媒体接收客户端，从而切换实际进行播放的媒体播放设备。
可见，根据本发明实施例提供的一种媒体处理方法，通过为多种通信协议 分别构建具有一个或多个媒体播放设备的媒体处理能力的一个或多个媒体接收客户端，接收媒体源设备发送的由所述媒体源设备指定的媒体接收客户端进行播放的待播放的媒体数据，将所述待播放的媒体数据发送给所述指定的媒体接收客户端对应的媒体播放设备进行播放，可以灵活地同时连接多个媒体播放设备并可在媒体播放过程中随意切换媒体播放设备。
请参阅图2，为本发明实施例提供的另一种媒体处理方法的流程示意图。该方法包括以下步骤：
步骤S201，媒体处理设备确定至少一种第一通信协议。
本步骤与前述实施例的步骤S101相同。在本实施例中，媒体处理设备可以是局域网路由器，如图3所示，为示例的一种媒体处理设备的结构示意图，该媒体处理设备为无线局域网(Wireless Local Area Network，WLAN)路由器1，该路由器1可以通过以太网/光纤/各种类型数字用户线路/第三代移动通信/长期演进等接口连入运营商网络或其它本地网络2，其与媒体源设备3通过第一通信协议对应的接口4进行通信，该媒体源设备3可以是手机、平板电脑等终端设备，该第一通信协议包括蓝牙协议、通用即插即用协议、数字生活网络联盟协议、智能分组和资源共享协议、AirPlay协议、无线高保真显示协议中的任意一种。
媒体处理设备在确定虚拟构建哪些第一通信协议的媒体接收客户端之前，可以通过WLAN、Wi-Fi Direct或蓝牙获取媒体源设备支持的协议种类，具体地，可以通过监听媒体源设备发送的多播报文或发出搜索请求并接收响应来确定有哪些第一通信协议的媒体源设备，从而确定第一通信协议。
步骤S202，所述媒体处理设备通过连接所述至少一个媒体播放设备的通信接口发现所述至少一个媒体播放设备，并获取所述至少一个媒体播放设备的媒 体处理能力和支持的第二通信协议。
媒体处理设备通过第二通信协议接口与媒体播放设备连接，通过监听通过该接口发来的消息等发现媒体播放设备，并获取媒体播放设备的媒体处理能力和支持的第二通信协议。如图3所示，媒体处理设备通过LAN接口6与媒体播放设备5连接，该第二通信协议包括高清晰度多媒体接口HDMI协议、显示接口DisplayPort协议、数字高清互动视音接口DiiVA协议、HDBaseT协议、移动高清连接MHL协议、Thunderbolt协议、无线千兆比特WiGig协议、无线家庭数字接口WHDI协议、WirelessHD协议中的任意一种。
其中的媒体处理能力可以为支持的媒体格式(例如，H.264、H.265、mp3、JPEG等)、支持的媒体类型(例如，视频、音频、音视频、图像)，支持的视频分辨率(例如，720p、1080p、4K、8K等)，支持的像素深度(例如，30比特/像素、36比特/像素、48比特/像素等)，支持的视频帧率(例如，24Hz、50Hz、60Hz等)，是否支持3D，支持的音频采样率(例如，32kHz、44.1kHz、48kHz等)等的任意一个或多个。
该接口信息还可包括：是否支持/启用传输控制协议/因特网互联协议(Transmission Control Protocol/Internet Protocol，TCP/IP)协议栈。该信息可以根据各类第二通信协议所定义的方式获取，如HDMI等可以通过能力发现控制(Capability Discovery Control，CDC)消息来探知媒体处理设备是否支持以太网，或者，通过检测该端口收到的报文来判断。
该接口信息还可包括：是否支持/开启网络之间互连的协议(Internet Protocol，IP)接收端。若某个局域网(Local Area Network，LAN)侧端口所接的设备支持TCP/IP协议栈，可以进一步判断是否支持UPnP/DLNA、AirPlay、IGRS等一个或多个协议接收端。
对于UPnP/DLNA，可以监听该端口是否发来简单服务发现协议(Simple Service Discovery Protocol，SSDP)宣告消息，以及SSDP宣告是否只是设备类型为“MediaRenderer”；
对于IGRS协议检测方式与SSDP报文类似；
对于AirPlay，可监听组播域名系统(Multicast Domain Name System，mDNS)报文以及其中的airplay(苹果公司制定的无线通讯技术)字段。
针对UPnP/DLNA设备，还可以进一步地判断该播放客户端支持的媒体格式，具体地，与该设备建立TCP连接，调用“GetProtocolInfo()action”来获得设备支持的媒体格式列表。
根据媒体播放设备是否已支持并运行上述UPnP/DLNA、AirPlay、IGRS等一个或多个协议接收端，如果已运行，则针对该媒体播放设备可以不用构建已支持并运行的媒体接收客户端。或者，进一步地根据媒体处理设备自身的媒体处理能力针对该媒体播放设备已支持并运行的媒体接收客户端，仍对应地构建媒体接收客户端，且构建的媒体接收客户端包含媒体播放设备上的媒体接收客户端不支持的但媒体处理设备支持的媒体能力。例如，媒体播放设备支持DLNA DMR客户端，其支持H.264,mp3,AAC,wmv等格式，媒体播放设备自身还支持mkv,vp8,H.265等格式，则虚拟出的DMR向网络宣告支持mkv,vp8,H.265等格式。
步骤S203，所述媒体处理设备针对所述每种第一通信协议，分别构建具有每个媒体播放设备的媒体处理能力的媒体接收客户端。
为每个LAN侧设备分别虚拟出一个或多个客户端。若某LAN侧设备仅支持高清音频或高清视频，则虚拟出的Wi-Fi/BT客户端相应地仅支持音频或视频播放能力；若某LAN侧设备支持音视频播放，则虚拟出的Wi-Fi/BT客户端支 持音视频。
对于UPnP/DLNA、IGRS协议，虚拟出MediaRenderer(DMR)并向局域网发送SSDP多播宣告，虚拟出的DMR继承WLAN路由器本身支持的媒体格式，网络中的CP可通过GetProtocolInfo()获取其支持的媒体格式列表。可选地，除了在WLAN通过IP多播宣告设备外，还可以向未接入WLAN的移动设备发送虚拟设备信息，如在收到某个移动终端发送的Wi-Fi查询消息(P2P Probe Request/Service Discovery Request)时返回携带虚拟设备信息(如“DLNA”、UUID、支持的媒体格式等)字段的响应(P2P Probe Response/Service Discovery Response)。
对于AirPlay协议，虚拟出一个播放器客户端并通过mDNS发送多播宣告，至少支持AAC、H.264、JPEG等媒体类型。
对于Wi-Fi Display(WFD)协议，虚拟出一个WFD接收端(Sink)，并通过Wi-Fi协议广播宣告设备信息，或在接收到移动设备发送的P2P查询消息时返回，至少支持L-PCM、H.264等解码器。
对于BT协议，虚拟出一个音频或A/V接收客户端，并通过BT机制广播宣告设备存在。
步骤S204，所述媒体处理设备通过所述第一通信协议对应的网络接口将所述至少一个媒体接收客户端的信息发送给媒体源设备。
媒体处理设备构建好媒体接收客户端后，通过该媒体接收客户端对应的第一通信协议广播该媒体接收客户端的存在，媒体源设备通过监听可以接收到其支持的第一通信协议对应的媒体接收客户端的信息，相反，对于不支持该第一通信协议的媒体源设备则接收不到或不会理解该媒体接收客户端的信息。
例如，移动终端发现网络中的媒体接收客户端，取决于移动终端支持且启 用的协议种类，比如移动终端只支持DLNA则无法发现其他客户端。
通过Wi-Fi发现DLNA、AirPlay、IGRS等媒体接收客户端可以有两种实现方式：
移动终端接入WLAN时，通过监听SSDP、mDNS报文获知有Sink设备，通过基于IP的多播/广播发现不仅发现了路由器上的虚拟客户端，还可能发现连接到该局域网的其他设备上的客户端。
移动终端未接入WLAN但开启Wi-Fi Direct扫描时，通过Wi-Fi Direct发现协议交互可获知路由器上运行了上述客户端；移动终端与路由器建立Wi-Fi Direct连接并分别获取IP地址，后与Sink建立TCP连接获取更详细的Sink端信息(支持的媒体种类和媒体格式列表等)。
通过BT发现A/V Sink：通过扫描可发现路由器上的BT设备，(自动或经用户确认)进行配对，若之前已配对过则直接建立BT连接。
步骤S205，所述媒体处理设备接收媒体源设备发送的由所述媒体源设备指定的媒体接收客户端进行播放的待播放的媒体数据。
经过步骤S204，媒体源设备上获取到上述一种或多种协议的媒体接收客户端列表，可以通过用户界面(User Interface，UI)展示给用户，并接收用户选择某个或多个进行播放。
针对播放本地存储的或网络上的媒体内容，具体处理方式可以为如下任意一种：
用户先在移动终端的浏览器或音乐/视频播放应用上选择要播放的媒体，媒体可以是媒体源设备本地存储的或者链接到网络上的。UI上提示用户可以播放到局域网的其他设备，用户点击后显示媒体接收客户端列表(名称和/或图标)，用户点击列表中的某个或多个媒体接收客户端完成选择。这种方式中，显示媒 体接收客户端列表可以有如下处理方式：
显示已发现的媒体接收客户端列表，每种协议客户端分别显示。此时，用户点击哪个播放设备图标则即确定了该媒体接收客户端设备也确定了交互协议。或者，
显示已发现的媒体接收客户端列表，仅显示通过某种协议发现的客户端。
媒体处理设备接收该待播放的媒体数据及媒体接收客户端的指定信息。
步骤S206，所述媒体处理设备将接收到的所述待播放的媒体数据按照所述指定的媒体接收客户端对应的第一通信协议进行解包和/或解码。
步骤S207，所述媒体处理设备将解包和/或解码后的所述待播放的媒体数据根据所述指定的媒体接收客户端对应的第二通信协议进行编码和/或封包。
路由器上虚拟出的播放客户端负责接受移动终端的控制和接收媒体流，路由器对接收到的媒体流进行处理再发送给媒体接收客户端对应的LAN侧接的实际媒体播放设备。具体的媒体处理为，对获取到的媒体流进行解包、解码，根据LAN侧对应设备不同的传输方式(HDMI、HDBaseT、WHDI等等)重新编码和/或重新封包，后将处理后的媒体数据发送给对应的媒体播放设备。
步骤S208，所述媒体处理设备将所述待播放的媒体数据通过所述指定的媒体接收客户端对应的第二通信协议发送给所述指定的媒体接收客户端对应的媒体播放设备进行播放。
LAN侧媒体播放设备对收到的来自路由器的媒体数据进行处理并呈现(音频或视频或音视频)，处理包括解封包和/或解码等。
以图3为例，以上步骤由无线局域网路由器1中的处理器7执行。
可见，根据本发明实施例提供的一种媒体处理方法，通过为多种通信协议分别构建具有一个或多个媒体播放设备的媒体处理能力的一个或多个媒体接收 客户端，接收媒体源设备发送的由所述媒体源设备指定的媒体接收客户端进行播放的待播放的媒体数据，将所述待播放的媒体数据发送给所述指定的媒体接收客户端对应的媒体播放设备进行播放，可以灵活地同时连接多个媒体播放设备并可在媒体播放过程中随意切换媒体播放设备。
请参阅图4，为本发明实施例提供的又一种媒体处理方法的流程示意图。该方法包括以下步骤：
步骤S301，媒体处理设备确定至少一种第一通信协议。
本步骤与上述实施例的步骤S201相同，在此不再赘述。
步骤S302，所述媒体处理设备读取与所述媒体处理设备连接的局域网路由器的端口信息表，从所述局域网路由器的端口信息表获取与所述路由器连接的所述至少一个媒体播放设备的媒体处理能力和支持的第二通信协议。
本实施例与上述实施例的不同在于，本实施例中的媒体处理设备并非直接连接媒体播放设备，无法直接获取连入局域网的媒体播放设备列表。这里提供的方案为媒体处理设备通过局域网路由器获取其各个LAN接口所接的设备的信息表。具体地，可以设计基于TCP/IP的端口信息读取指令，例如，定义UPnP协议“action”获取，也可以使用HTTP、DHCP或其他协议获取。路由器LAN侧设备接口信息表包括与局域网路由器连接的多个媒体播放设备的媒体处理能力和支持的第二通信协议。
步骤S303，所述媒体处理设备将所述至少一个媒体播放设备的媒体处理能力组合为至少一类媒体处理能力。
步骤S304，所述媒体处理设备针对所述每种第一通信协议，分别构建具有每类组合的媒体处理能力的媒体客户端。
例如，为至少2个LAN侧设备组合虚拟出一个媒体接收客户端，可针对LAN侧设备为功能单一的外设，如一个为显示器只支持视频输出、一个为音响仅支持音频输出。WLAN路由器可据此为上述一种或多种Wi-Fi/BT协议分别虚拟出一个组合客户端。这个客户端对外宣告是一个A/V播放设备。这里至少2个LAN侧设备不限于通过一种连接方式接到路由器，也可以是通过不同线缆/无线连接的，如一个通过HDMI另一个通过HDBaseT连，又如一个通过HDBaseT另一个通过WHDI连。
为部分LAN侧设备单独虚拟媒体接收客户端，并采用组合虚拟的方式处理其他LAN侧设备。例如，LAN侧设备支持A/V则单独虚拟，LAN侧设备仅支持音频/视频、则与另一个仅支持视频/音频的设备组合虚拟。
步骤S305，所述媒体处理设备通过所述第一通信协议对应的网络接口将所述至少一个媒体接收客户端的信息发送给媒体源设备。
显示已发现的媒体接收客户端列表，并按发现物理设备整合显示。例如，根据IP地址和/或MAC地址和/或BT设备地址将同一个物理设备上的多个客户端整合显示成一个播放设备(一个名称和/或一个图标)。
步骤S306，所述媒体处理设备接收所述媒体源设备发送的所述待播放的媒体数据的网络地址。
步骤S307，所述媒体处理设备根据所述网络地址获取所述待播放的媒体数据。
如果待播放的媒体数据不是媒体源设备本地存储的，而是存储在网络上的，则媒体源设备返回的可以是待播放的媒体数据的网络地址，媒体处理设备再根据该网络地址从网络上获取待播放的媒体数据。其获取技术与现有技术相同，在此不再赘述。
步骤S308，所述媒体处理设备将获取到的所述待播放的媒体数据按照所述指定的媒体接收客户端对应的第一通信协议进行解包和/或解码。
步骤S309，所述媒体处理设备将解包和/或解码后的所述待播放的媒体数据根据所述指定的媒体接收客户端对应的第二通信协议进行编码和/或封包。
步骤S308和步骤S309分别与前述实施例的步骤S206和步骤S207相同，在此不再赘述。
步骤S310，所述媒体处理设备分别通过所述指定的具有组合的媒体处理能力的媒体接收客户端分别对应的第二通信协议，将所述待播放的媒体数据的音频和/或视频同步发送给所述指定的媒体接收客户端对应的至少两个媒体播放设备进行播放。
针对一个虚拟客户端对应多个设备时(如音、视频分别输出给2个设备，或多声道音频分别输出给多个音响，或多个设备同时播放同一媒体)，发送媒体流多个高清设备时还需要控制同步，即向多个设备发送同步时钟信息和/或精确控制多路数据发送时的同步性。
可见，根据本发明实施例提供的一种媒体处理方法，通过为多种通信协议分别构建具有一个或多个媒体播放设备的媒体处理能力的一个或多个媒体接收客户端，接收媒体源设备发送的由所述媒体源设备指定的媒体接收客户端进行播放的待播放的媒体数据，将所述待播放的媒体数据发送给所述指定的媒体接收客户端对应的媒体播放设备进行播放，可以灵活地同时连接多个媒体播放设备并可在媒体播放过程中随意切换媒体播放设备。

由于构建的媒体接收客户端对应一个或多个媒体播放设备，各媒体播放设备与媒体处理设备通过第二通信协议通信，该第二通信协议可以为一种或多种，第二发送单元16将接收到的待播放的媒体数据通过第二通信协议发送给指定的媒体接收客户端对应的媒体播放设备进行播放。
在本实施例中，多个媒体播放设备与媒体处理设备连接，媒体源设备可以对应多个媒体接收客户端，每个媒体接收客户端具有相应的媒体处理能力，媒体源设备只需根据待播放的媒体数据与媒体接收客户端的媒体处理能力进行匹配或根据用户的操作指示，指定进行播放的媒体接收客户端，媒体处理设备接收到待播放的媒体数据后即可发送给指定的媒体接收客户端对应的媒体播放设备，由于媒体源设备对应的是虚拟构建的媒体接收客户端，可以随意切换媒体接收客户端，从而切换实际进行播放的媒体播放设备。

请参阅图6，为本发明实施例提供的另一种媒体处理设备的结构示意图，该媒体处理设备2000包括：
确定单元21，用于确定至少一种第一通信协议。
本实施例的确定单元21与前述实施例的确定单元11相同。在本实施例中，媒体处理设备可以是局域网路由器，如图3所示，为示例的一种媒体处理设备 的结构示意图，该媒体处理设备为无线局域网(Wireless Local Area Network，WLAN)路由器1，该路由器1可以通过以太网/光纤/各种类型数字用户线路/第三代移动通信/长期演进等接口连入运营商网络或其它本地网络2，其与媒体源设备3通过第一通信协议对应的接口4进行通信，该媒体源设备3可以是手机、平板电脑等终端设备，该第一通信协议包括蓝牙协议、通用即插即用协议、数字生活网络联盟协议、智能分组和资源共享协议、AirPlay协议、无线高保真显示协议中的任意一种。
媒体处理设备在确定虚拟构建哪些第一通信协议的媒体接收客户端之前，可以由确定单元21通过WLAN、Wi-Fi Direct或蓝牙获取媒体源设备支持的协议种类，具体地，可以通过监听媒体源设备发送的多播报文或发出搜索请求并接收响应来确定有哪些第一通信协议的媒体源设备，从而确定第一通信协议。

根据媒体播放设备是否已支持并运行上述UPnP/DLNA、AirPlay、IGRS等一个或多个协议接收端，如果已运行，则针对该媒体播放设备可以不用构建已支持并运行的媒体接收客户端。或者，进一步地根据媒体处理设备自身的媒体处理能力针对该媒体播放设备已支持并运行的媒体接收客户端，仍对应地构建媒体接收客户端，且构建的媒体接收客户端包含媒体播放设备上的媒体接收客户端不支持的但媒体处理设备支持的媒体能力。例如，媒体播放设备支持DLNADMR客户端，其支持H.264,mp3,AAC,wmv等格式，媒体播放设备自身还支持mkv,vp8,H.265等格式，则虚拟出的DMR向网络宣告支持mkv,vp8,H.265等格式。对于这种情况，第一构建单元可包括：
