Description

多语言视频发射/接收系统
技术领域
本发明涉及一种电视广播系统，并且特别涉及一种多语言视频发射/接收系统，能够在广播信道上传送每个具有多语言音频信息的多个视频信息，以便在用户接收机选择任何视频信息和嵌入视频信息的任何音频信息。
背景技术
全世界已经对卫星通信进行了许多研究，并且最近卫星被用于远程视频会议和本地电视广播。
卫星通信具有宽带数据传输的许多优点，因而能够提供高质量的电视广播，并且覆盖地球的所有区域或者使用扰频信号定位广播区域。
即使卫星广播能够覆盖整个世界，它也有缺点：当音频信号分配给当前语言不同于音频信号的语言的区域时，音频信号语言应当同时被翻译成区域的当前语言或者应当提供通用语言字幕服务。
发明内容
本发明努力解决以上问题。
本发明的目的是提供一种多语言视频发射/接收系统，能够在广播信道上传送多个视频信息，每个视频信息信道具有多个音频信息信道，从而一种音频信息和相应的视频信息一起被视频接收机选择地接收。
为了实现以上目的，本发明的多语言视频发射/接收系统包括多路复用装置，用于将多个音频信息信道嵌入多个视频信息信道的每一个中并且产生组合视频信号，多个用户接收装置，用于接收组合视频信号，从组合视频信号选择一个视频信息信道，并且选择嵌入选定视频信息信道的一个音频信息信道。
附图简述
发明的以上和其它目的和特征将通过以下结合相应附图的优选实施例的说明更加清楚，其中：
图1是说明按照本发明优选实施例的多语言视频发射/接收系统的框图；
图2是说明按照本发明另一实施例的多语言视频发射/接收系统的发射机的示意图；和
图3是说明按照本发明另一实施例的多语言视频发射/接收系统的接收机的示意图；
图4是说明按照本发明另一实施例的多语言视频发射/接收系统的接收机的示意图。
实施例详述
本发明的优选实施例将参考相应附图在下文中说明。
本发明提供一种多语言视频发射/接收系统，能够在广播信道上传送每个嵌有多语言音频信息的多个视频信息。例如，在广播服务向全世界或一些指定国家提供以及要求从多个国家向住在旅馆的客户提供广播服务的情况中，多语言信道给予居住在不同国家以及住在旅馆不同房间的人们选择权以便选择语言。
图1是说明本发明的多语言视频发射/接收系统的框图。
如图1A和图1B所示，本发明的多语言视频发射/接收系统包括多路复用装置10，具有天线25的发射器20，具有收发器30和30’的卫星转发器40，具有天线25’的多个用户接收装置50。
多路复用装置10包括：多个音频信道复用器11，用于将多种语言的音频信息A1，A2，…，和An嵌入多种视频信息V1，V2，…，和Vn，和视频信道复用器12，用于在宽带信道中传送视频信息。
用户接收装置50包括高频接收器51，用于接收广播信号，连接高频接收器51的视频信道去复用器52，用于从广播信号去复用视频信道，连接视频信道去复用器52的第一开关SW1，用于选择任意去复用的视频信道，音频信道去复用器53，用于去复用嵌入每个视频信道的音频信道，连接音频信道去复用器53的第二开关SW2，用于选择任意去复用的音频信道，和多个音/视频协调器54，用于合并第二开关SW2选择的音频信道和第一开关SW1选择的视频信道。每个音/视频协调器54可以连接电视机或耳机。第一和第二开关SW1和SW2可以是机械开关、电磁开关或代码开关。
图2示出了按照本发明第二实施例的多语言视频发射/接收系统的发射机。图3示出了按照本发明第三实施例的多语言视频发射/接收系统的接收机，而图4示出了按照本发明第四优选实施例的多语言视频发射/接收系统的接收机。
如图2所示，发射机60将不同音频信道的多个音频信息A1，A2，A3，…，An嵌入视频信息V，然后经天线将视频信息发射到空中。
如图3所示，接收机70接收每个具有多个音频信息的多个视频信息，然后任意视频信息被视频选择开关SWV选择，并且嵌入选定视频信息的任意音频信息被音频选择开关SWA选择。
如图4所示，接收机80接收每个具有多个音频信息的多个视频信息，然后任意视频信息信道被视频选择开关SWV选择，并且嵌入视频信息的任意音频信息信道被安装在接收机80中的音频信息滤波器81滤波。
如上构成的多语言视频发射/接收系统的操作将在下文中说明。
多路复用装置10的每个音频信道复用器11将多种语言的音频信息A1，A2，…，An嵌入各视频信息V1，V2，V3，…，Vn，然后将视频信息发送给视频信道复用器12。视频信道复用器12在宽带信道上传送来自音频信道复用器11的所有视频信息流，然后向发射器20发送复用的视频信息。发射器20经天线25将视频信息发射到卫星转发器40。卫星转发器40经收发器30接收视频信息并经另一收发器30’将其广播到空中。多语言视频信息可以经无线信道、同轴电缆或光纤从发射器20发送到用户接收装置，而不使用卫星转发器。
广播的视频信息经天线25’被用户接收装置50的高频接收器51接收，然后被视频信道去复用器52去复用。接下来，任意视频信道被第一开关SW1选择。选定的视频信道包含多个音频信道，从而视频信道的音频信道被音频信道去复用器53去复用，然后任意音频信道被第二开关SW2选择。被第一和第二开关SW1和SW2选择的视频和音频信道被一个音/视频协调器54合并，并经电视机或耳机输出。
用户接收装置50配备有多个音/视频协调器并且每个音/视频协调器具有与用于操作第二开关的调谐器连接的输出接口，从而用户能够选择任意语言的音频信道。
因为图2和图3中的发射机60和接收机70的操作类似多路复用装置10和用户接收机50的操作，所以发射机60和接收机70的操作细节不再说明。
对于图4，接收机80接收广播信号，然后具有多个音频信息的一个视频信息被开关SWV选择，并且多个音频信息的特定的一个被滤波器81滤波。因此，接收机80能够仅以一种语言音频信息提供视频信息。
如上所述，在本发明的多语言语音嵌入视频发射/接收系统中，多个语言音频信息被嵌入视频信息中，从而用户能够用任意音频信息的语言观看视频，而不管他/她在世界的何处。
而且，在使用多语言语音嵌入视频发射/接收系统的电话会议的情况中，多个音频信道被提供，通信能够被交互执行，而不用翻译。
虽然该发明已经结合目前认为是最实际和优选的实施例被说明，但是应当理解，本发明不限于公开的实施例，相反，应当覆盖所附权利要求的宗旨和范围内包括的各种修改和等效配置。
