Description

一种媒体数据的发送方法、装置和机顶盒 技术领域
本发明涉及数字电视技术领域，特别是涉及一种媒体数据的发送方法、装置和机顶盒。
背景技术
随着国家三网融合试点工作的持续深入推进以及电信运营商宽带提速工程的不断加快，IPTV(交互式网络电视，Internet Protocol Television)进入快速发展期，同时伴随着电视广播的全面数字化，传统的有线数字电视全面进入数字化时代，机顶盒走进千家万户。
机顶盒作为用户接收端设备，与承载网络连接，将接收到的数据转换成电视屏幕可以显示的数据。然而目前机顶盒的现状是，一个机顶盒输出相同的内容给一个或多个电视机。若每个电视机配置一个机顶盒，则布线较为麻烦，不仅影响美观，且成本很高，因此目前许多家庭，一般只配置一台机顶盒，这样就存在某一个家庭成员在收看节目，其他家庭成员也只能跟着收看相同的节目。而大多数情况下家庭成员间的需求是有差异的，例如有的家庭成员喜欢娱乐节目，有的家庭成员喜欢体育节目。因此，现有技术对于家庭成员享受个性化差异的音视频服务是十分不利的。
发明内容
本发明实施例提供了一种媒体数据的发送方法、装置和机顶盒，用以至少解决现有技术一台机顶盒为不同终端只能提供相同媒体数据的问题。
针对上述技术问题，本发明实施例是通过以下技术方案来解决的。
本发明实施例提供了一种媒体数据的发送方法，包括：接收不同终端发送的节目播放请求；其中，所述节目播放请求中包括显示终端信息和节目链接地址；获取与每个所述节目链接地址相对应的媒体数据；根据每个所述显示终端信息，将媒体数据发送给与之对应的终端。
本发明实施例还提供了一种媒体数据的发送装置，包括：接收模块，设置为接收不同终端发送的节目播放请求；其中，所述节目播放请求中包括显示终端信息和节目 链接地址；获取模块，设置为获取与每个所述节目链接地址相对应的媒体数据；发送模块，设置为根据每个所述显示终端信息，将媒体数据发送给与之对应的终端。
本发明实施例还提供了一种机顶盒，包括上述任一所述的装置；其中，所述机顶盒还包括：解码模块，设置为将所述装置获取的媒体数据解码后发送给显示器；数据传输模块，设置为将来自移动终端的节目播放请求转发给所述装置，并将所述装置获取的媒体数据转发给对应的移动终端。
其中，如果所述显示终端信息为空值，则所述装置将节目链接地址对应的媒体数据通过所述解码模块发送给所述显示器；如果所述显示终端信息为地址，则所述装置将节目链接地址对应的媒体数据通过数据传输模块发送给与之对应的移动终端。
本发明实施例有益效果如下：
本发明实施例根据不同终端的显示终端信息，将从服务器下载的一个或多个媒体数据(节目)传送给相应的终端，使不同的终端可以享受不同的节目，满足了多用户个性化需求，提高了用户体验效果。

图4是根据本发明一实施例的媒体数据的发送装置的结构图。
具体实施方式
为了解决现有技术一台机顶盒为不同用户只能提供相同媒体数据(节目)的问题，本发明提供了一种媒体数据的发送方法、装置和机顶盒，以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
本发明实施例提供了一种机顶盒，该机顶盒设置为向不同终端传送不同的媒体数据。终端设置为显示机顶盒传送的媒体数据。该终端包括移动终端和显示器。该移动终端例如是手机、平板电脑、笔记本电脑等。该显示器例如是电视机。
下面结合媒体数据的发送的***对本发明实施例的机顶盒的功能进行说明。
如图1所示，图1是根据本发明一实施例的用于节目传送的***的结构图。
在该***中可以包括电视机110、移动终端120、机顶盒130、服务器140。
电视机110和移动终端120可以设置为向机顶盒130发送节目播放请求。
具体而言，使用电视机110的用户可以被称作电视机用户。电视机用户可以通过特定设备向机顶盒130发送节目播放请求，该节目播放请求设置为请求播放用户所需的媒体数据。例如：特定设备可以是机顶盒遥控器，电视机用户可以通过机顶盒遥控器选择所需的节目A，该选择操作即可触发机顶盒遥控器向机顶盒130发送关于节目A的节目播放请求。此外，电视机110还可以设置为显示机顶盒130传送的媒体数据。使用移动终端120的用户可以被称作移动终端用户。移动终端用户可以通过在移动终端120中选择所需的媒体数据，进而触发移动终端120向机顶盒130发送节目播放请求。例如：当移动终端为智能手机时，则移动终端用户在智能手机中输入或选择所需的媒体数据，如，输入或选择“新闻联播”，当移动终端侦测到该输入或选择操作后，则向机顶盒130发送针对“新闻联播”的节目播放请求。此外，移动终端120可以设置为显示机顶盒130传送的媒体数据。
在节目播放请求中可以包括显示终端信息、节目链接地址。电视机110的显示终端信息为空值，移动终端120的显示终端信息为该移动终端120的地址。如，移动终端120的互联网协议地址(Internet Protocol Address，IP)和/或介质访问控制地址(Media Access Control，MAC)。节目链接地址是媒体数据在服务器140中的存储地址。
机顶盒130设置为接收电视机和/或移动终端所发送的节目播放请求，也即是接收电视机用户和/或移动终端用户所触发的节目播放请求，并基于该节目播放请求向服务器140请求与该节目播放请求对应的媒体数据，以及在对服务器140返回的媒体数据进行处理后，传送给相应的电视机110或移动终端120，以供电视机用户或移动终端用户观看节目。
进一步地，在机顶盒130中至少包括：网络数据处理模块131、转发播放预处理模块132、解码模块133和数据传输模块134。
当电视机用户和/或移动终端用户触发节目播放请求的发送时：
数据传输模块134可以设置为将移动终端用户触发的节目播放请求转发至转发播放预处理模块132。
转发播放预处理模块132可以设置为接收使用不同终端的用户所触发的节目播放请求。例如：可以接收数据传输模块134转发的移动终端用户触发的节目播放请求，还可以接收电视机用户通过机顶盒遥控器触发的节目播放请求。
转发播放预处理模块132可以根据节目播放请求中的节目链接地址形成媒体数据请求。该媒体数据请求设置为请求服务器140返回与节目链接地址相对应的媒体数据。
具体而言，节目链接地址可以是用户所需的媒体数据的网络地址。转发播放预处理模块132可以将节目播放请求中的显示终端信息和节目链接地址进行剥离，并基于节目链接地址形成媒体数据请求。在该媒体数据请求中可以包括机顶盒信息、节目链接地址。该机顶盒信息可以是机顶盒130的IP地址、MAC地址等信息。
转发播放预处理模块132将媒体数据请求发送至网络数据处理模块131。网络数据处理模块131设置为将该媒体数据请求转发至服务器140。
服务器140设置为存储一个或多个媒体数据。服务器140根据接收到的媒体数据请求与机顶盒130建立节目链接。具体链接时，根据媒体数据请求中的机顶盒信息和节目链接地址，服务器140可以根据节目链接地址与相应的机顶盒130建立节目链接，以将节目链接地址指向的媒体数据发送给机顶盒130。进一步地，该媒体数据以媒体数据流的形式发送至机顶盒130，换言之，媒体数据可以包括一个或多个媒体数据流。
当机顶盒130需要向终端传送媒体数据时：
网络数据处理模块131可以设置为接收来自服务器140的一个或多个媒体数据流，并对接收到的一个或多个媒体数据流进行重新排序和传输校验，使一个或多个媒体数据流组成一个或多个媒体数据。
具体而言，在每个媒体数据流中可以包括该媒体数据流所属的节目链接地址、该媒体数据流在媒体数据中所处的位置(编号)等信息，基于这些信息可以将同一个节目链接地址的一个或多个媒体数据流重新组成媒体数据。针对重新组成的媒体数据可以进行传输校验。例如：可以根据媒体数据中缺少的媒体数据流，来判断媒体数据是否存在严重的丢包情况。
转发播放预处理模块132可以设置为将媒体数据中的每个媒体数据流还原为媒体数据帧，并按照请求该媒体数据的显示终端信息，将电视机110所需的媒体数据帧发送给解码模块133，将移动终端120所需的媒体数据帧通过数据传输模块134发送给相应的移动终端120。
解码模块133可以设置为对接收到的每个媒体数据帧进行解码，以将媒体数据帧解码为可以在电视机110中显示的音、视频信号。
移动终端120还可以设置为解码接收到的每个媒体数据帧，以将媒体数据帧解码为可以在移动终端120中显示的音、视频信号。
基于上述机顶盒130，本发明实施例提供了一种用于节目传送的方法。如图2所示，图2是根据本发明一实施例的用于节目传送的方法的流程图。
步骤S210，接收不同终端发送的节目播放请求。
该节目播放请求可以设置为请求播放用户所需的节目。可以由机顶盒130来接收该节目播放请求。
节目播放请求中包括显示终端信息和节目链接地址。节目链接地址是媒体数据在服务器140中的存储地址。终端设置为显示媒体数据。进一步地，终端可以包括电视机110和移动终端120。其中，电视机110的显示终端信息为空值，移动终端120的显示终端信息为移动终端120的地址。移动终端120的地址可以是移动终端120的IP地址和/或MAC地址。
例如：该节目播放请求为了请求播放节目A。进一步地，用户可以是使用电视机110的用户也可以是使用移动终端120的用户。移动终端120例如是智能手机、平板电脑、笔记本电脑等可以播放音视频信号的终端。
步骤S220，获取与每个节目链接地址相对应的媒体数据。
基于节目播放请求，机顶盒130可以向服务器140发送媒体数据请求。该媒体数据请求设置为请求服务器140返回与节目链接地址相对应的媒体数据。媒体数据请求中可以包括节目链接地址、机顶盒130的地址。机顶盒130的地址可以是机顶盒130的IP地址和/或MAC地址。
具体而言，机顶盒130根据节目播放请求中节目链接地址，可以请求服务器140返回与该节目链接地址相对应的媒体数据。根据节目链接地址而形成的媒体数据请求，即是为了请求服务器140返回与该节目链接地址相对应的媒体数据流。例如：节目播放请求包含节目A的链接地址，所以该节目播放请求是为了请求播放节目A，机顶盒130根据节目A的链接地址和机顶盒130的地址形成媒体数据请求，向服务器140请求返回节目A的媒体数据。
步骤S230，根据每个显示终端信息，将媒体数据发送给与之对应的终端，以在终端中显示媒体数据。
基于已发送的媒体数据请求，机顶盒130可以接收来自服务器140的一个或多个媒体数据。每个媒体数据与一个节目播放请求中的节目链接地址对应。
由于用户触发的节目播放请求中包括显示终端信息和节目链接地址，所以，如果节目播放请求中的显示终端信息为空值，则机顶盒130可以将根据节目播放请求中的节目链接地址所返回的媒体数据向电视机110传送；如果节目播放请求中的显示终端信息为地址，则机顶盒130可以将根据节目播放请求中的节目链接地址所返回的媒体数据向地址对应的移动终端120传送。
进一步地，服务器140是以媒体数据流的形式向机顶盒130返回媒体数据的。服务器140返回的一个或多个媒体数据流可以组成一个或多个媒体数据。换言之，服务器140返回的每个媒体数据都包括一个或多个媒体数据流。
机顶盒130中的网络数据处理模块可以对接收到的一个或多个媒体数据流进行排序，使排序后的一个或多个媒体数据流可以组成一个媒体数据，该排序顺序可以参照每个媒体数据流在媒体数据中的播放顺序。
机顶盒130中的转发播放预处理模块可以按照每个媒体数据中的一个或多个媒体数据流的播放顺序，将每个媒体数据流还原为媒体数据帧；以及将每个媒体数据帧传送给相应的终端。
如果节目播放请求中的显示终端信息为空值，则机顶盒130中的解码模块可以将每个所述媒体数据帧解码为音视频信号后传送给相应的终端。该终端可以是电视机110，电视机110可以显示该音、视频信号。
如果节目播放请求中的显示终端信息为地址，则机顶盒130中的数据传输模块可以可以将每个所述媒体数据帧传送给相应的终端。该终端可以是显示终端信息(地址)所对应的移动终端120。由移动终端120将每个媒体数据帧解码为音视频信号，并在移动终端120中显示该音视频信号。
如图3所示，图3是根据本发明一实施例的用于节目传送的方法的流程示意图。以针对图2中的步骤S210-S230进行详细说明。
步骤S301-步骤S308，为使用电视机110作为终端的用户启动、关闭节目的操作步骤。
步骤S301，用户触发节目播放请求。
具体而言，电视机110用户可以使用机顶盒130遥控器来选择想要观看节目A。该选择操作可以直接触发机顶盒130播放节目A的命令。在该节目播放请求中包括显示终端信息和节目链接地址。
步骤S302，机顶盒130收到来自用户的节目播放请求，并与服务器140建立与节目链接地址对应的节目链接。
具体而言，机顶盒130被触发播放节目A的命令后，向服务器140发出建立节目A的链接。进一步地，如果电视机110当前正在播放其它节目，则先关闭当前播放的节目，再向服务器140发出请求以建立节目A的链接。
步骤S303，服务器140向机顶盒130返回节目的媒体数据流，并由机顶盒130对该节目的媒体数据流进行处理，以得到该节目的媒体数据帧。
具体而言，节目A的链接建立成功后，服务器140向机顶盒130返回节目A的媒体数据流。节目A包括一个或多个媒体数据流。每个媒体数据流到达机顶盒130的网络数据处理模块131处，机顶盒130的网络数据处理模块131接收媒体数据流，并对该媒体数据流进行重新排序和传输校验。网络数据处理模块131将重排序后，并且传输校验通过的媒体数据流传送给转发播放预处理模块132。转发播放预处理模块132将媒体数据流还原为媒体数据帧。由于发送节目播放请求的用户是电视机110用户，所以，转发播放预处理模块132将媒体数据帧发送至解码模块133，待解码模块133对媒体数据帧进行解码输出。
步骤S304：机顶盒130发送解码后的媒体数据帧至电视机110用户，以供用户观看。
解码模块133对接收到的节目A的媒体数据帧进行解码，以将该媒体数据帧转换为电视机110可以显示的音视频信号，并且解码模块133将节目A的音视频信号输出给电视机110，使该电视机110用户可以观看节目A的内容。
步骤S305，用户触发停止播放当前节目的请求。该当前节目可以是节目A。
步骤S306，机顶盒130根据接收到的停止播放当前节目的请求，停止向该用户发送该节目解码后的媒体数据帧。进一步地，机顶盒130中的解码模块133可以停止对节目A的解码。
步骤S307，机顶盒130在停止向用户发送节目的媒体数据帧时，关闭该节目的节目链接。
步骤S308，服务器140根据已经断开的链接，停止向机顶盒130返回节目的媒体数据流。
步骤S309-步骤S316，为使用移动终端120为终端的用户启动、关闭节目的操作步骤。步骤S301-步骤S308与步骤S309-步骤S316可以并行进行。
步骤S309，用户触发节目播放请求。
用户在所使用的移动终端120中选择节目。例如：用户希望观看节目B，则可以在移动终端120中选择节目B。移动终端120侦测到用户选择节目B的操作后，则向机顶盒130发送播放节目B的节目播放请求。
步骤S310，机顶盒130收到移动终端120发送的节目播放请求后，与服务器140建立与节目链接地址对应的节目链接。例如：机顶盒130接收到来自移动终端120的节目播放请求，该请求设置为播放节目B。根据该节目播放请求中的节目B的节目链接地址，机顶盒130向服务器140发出请求以建立节目B的链接。
步骤S311，服务器140向机顶盒130返回该节目的媒体数据流，并由机顶盒130对该节目的媒体数据流进行处理，以得到该节目的媒体数据帧。
具体而言，节目B链接建立成功后，服务器140向机顶盒130返回节目B的每个媒体数据流，每个媒体数据流到达机顶盒130的网络数据处理模块131处，机顶盒130的网络数据处理模块131接收到该节目B的媒体数据流后，对该媒体数据流进行重新排序和传输校验。由转发播放预处理模块132将重排序且校验通过后的媒体数据流还原为媒体数据帧。由于发送节目播放请求的用户是移动终端120用户，所以，转发播放预处理模块132将该媒体数据帧转发给数据传输模块134，待数据传输模块134对该媒体数据帧进行进一步地处理。
步骤S312，机顶盒130发送媒体数据帧至相应的移动终端120，以供用户观看。
数据传输模块134接收到节目B的媒体数据帧后，将节目B的媒体数据帧传输给相应的移动终端120，该移动终端120是发送针对节目B的节目播放请求的移动终端120。
移动终端120接收到机顶盒130转发的媒体数据帧后，对该媒体数据帧进行解码，将媒体数据帧转换为可以在移动终端120上显示的音视频信号，使该移动终端120可以播放该节目B。
步骤S313，用户触发停止播放当前节目的请求。
移动终端120根据用户选择停止的节目，向机顶盒130发出停止播放当前节目的请求。该当前节目例如是节目B。进一步地，移动终端120可以侦测用户选择的操作，当判断出为停止播放节目B时，则向机顶盒130发送停止播放节目B的请求。
步骤S314，机顶盒130根据接收到的停止播放当前节目的请求，停止向该移动终端120发送该节目的媒体数据帧。进一步地，机顶盒130中的解码模块133可以停止对节目B的解码，以实现停止向移动终端120发送节目B的媒体数据帧。
步骤S315，机顶盒130在停止向用户转发节目的媒体数据帧时，关闭该节目的节目链接。
步骤S316，服务器140根据已经断开的链接，停止向机顶盒130返回节目的媒体数据流。
进一步地，节目A的播放和停止、节目B的播放和停止可以并行进行，节目A的播放和停止对节目B的播放和停止没有影响。
本发明实施例还提供了一种媒体数据的发送装置。图4是根据本发明一实施例的媒体数据的发送装置的结构图。
该装置包括：接收模块410，设置为接收不同终端发送的节目播放请求；其中，节目播放请求中包括显示终端信息和节目链接地址。节目链接地址是媒体数据在服务器中的存储地址；终端包括显示器和移动终端；其中，显示器的显示终端信息为空值，移动终端的显示终端信息为移动终端的地址。
获取模块420，设置为获取与每个节目链接地址相对应的媒体数据；
发送模块430，设置为根据每个显示终端信息，将媒体数据发送给与之对应的终端。如果显示终端信息为空值，则将节目链接地址对应的媒体数据向显示器传送；如果显示终端信息为地址，则将节目链接地址对应的媒体数据向地址对应的移动终端传送。
发送模块430，设置为：每个媒体数据包括一个或多个媒体数据流；按照媒体数据中的一个或多个媒体数据流的播放顺序，将每个媒体数据流还原为媒体数据帧；将每个媒体数据帧发送给与之对应的终端。
由于本实施例的装置所实现的功能基本相应于前述图1至图3所示的***、方法实施例，故本实施例的描述中未详尽之处，可以参见前述实施例中的相关说明，在此不做赘述。
尽管为示例目的，已经公开了本发明的优选实施例，本领域的技术人员将意识到各种改进、增加和取代也是可能的，因此，本发明的范围应当不限于上述实施例。
