Description

蓝牙子母立体双声道的数字电视
技术领域
本发明涉及一种立体双声道的数字电视，尤其涉及一种蓝牙子母立体双声道的数字电视。
背景技术
随着生活水平的提高，人们开始对视觉及听觉的质量要求越来越高了。而数字电视顺应了这一要求，因此目前数字电视得到极大的推广与普及。伴随着数字电视的发展技术越来越成熟，越来越多的附加功能被集成到数字电视中。如，子母画面的数字电视。当一家人坐在一块看电视时，可以因各人的喜好选择自己喜欢的电视节目，并同时在一个屏幕上同时播放两个节目。如图1所示，为现有子母画面的数字电视的结构示意图。该子母画面的数字电视包括串连连接着的天线1、数字电视调谐器2、微处理器3、子母画面处理器4及音频解码器6。所述的子母画面处理器4在接收到用户通过遥控器或者电视按钮所选择的频道信息，子母画面处理器4从微处理器3传送过来的数字信号中撷取出对应用户选择频道的数字信号，并将对应两个选择频道的视频数据分别根据两个数据线传送至视频解码器5进行解码，经解码后分别在所述数字电视的子画面或母画面分别播放。但是对应两个不同的频道的音频数据仅能通过一个音频解码器6进行解码。
上述子母画面的数字电视虽然能够同时提供子母画面供用户观看，但其仅单纯提供子母画面却没法提供子母声道；或者即使能够提供子母声道，也仅能分别从左右喇叭输出子声道与母声道而无法提供立体声道。
发明内容
鉴于以上内容，本发明较佳实施例提供一种蓝牙子母立体双声道的数字电视，其解决了现有数字电视无法输出子母立体双声道的问题。
一种蓝牙子母立体双声道的数字电视，所述数字电视包括串连连接着的天线、数字电视调谐器、微处理器及子母画面处理器，所述数字电视还包括分别连接所述子母画面处理器的第一音频解码器及第二音频解码器，所述第一音频解码器及第二音频解码器的另一端分别连接第一蓝牙传输器及第二蓝牙传输器，其中：
所述的子母画面处理器用于，当接收到用户选择的两个频道信息后，将微处理器传送过来的数字电视信号过滤出对应上述两个频道的数字电视信号，从上述两个频道的数字电视信号中过滤出两组音频数据，并分别将所述两组音频数据传送至第一音频解码器及第二音频解码器；
所述第一音频解码器及第二音频解码器用于将接收到的两组音频数据进行解码，并将解码后的音频数据分别传送至第一蓝牙传输器及第二蓝牙传输器；及
所述的第一蓝牙传输器及第二蓝牙传输器用于将接收到的解码后的音频数据转换成模拟的信号以实现子母立体双声道。
相较于现有技术，所述的蓝牙子母立体双声道的数字电视，当用户选择两个频道后，子母画面处理器过滤出对应所选择的两个频道的两组音频数据，并将所述两组音频数据分别传送至第一音频解码器及第二音频解码器，所述第一音频解码器及第二音频解码器分别将解码后的音频数据传送到第一蓝牙传输器及第二蓝牙传输器，所述第一蓝牙传输器及第二蓝牙传输器将所述的音频数据转换成模拟的立体双声。利用本发明，用户可以分别独立收听两个频道的立体声(即子母立体双声道)而免受相互干扰以保证最佳的音质效果。
附图说明
图1是传统的双声道的数字电视的架构图。
图2是本发明的蓝牙子母立体双声道的数字电视的较佳实施例的架构图。
具体实施方式
参阅图2所示，是本发明蓝牙子母立体双声道的数字电视的较佳实施例的硬件架构图。该子母画面的数字电视包括串连连接着的天线1、数字电视调谐器2、微处理器3、子母画面处理器4。所述天线1接收外界的RF(Radio Frequency，射频)数字电视信号并将它传送至数字电视调谐器2。该数字电视调谐器2将接收至的RF数字电视信号转换成数字信号，并过滤出所需的数字电视信号将它传送至微处理器3。微处理器3将所述数字电视信号转换成数字电视可识别格式，该格式的数字电视信号包括声音和图像，然后微处理器3将转换后的数字电视信号传送至子母画面处理器4。所述的子母画面处理器4根据接收到的用户通过遥控器或者电视按钮所选择的两个频道信息从微处理器3传送过来的转换格式的数字电视信号中撷取出对应用户选择频道的视频数据，并将该对应两个选择频道的视频数据分别通过两个数据线传送至视频解码器5进行解码，经解码后分别在所述数字电视的子画面或母画面进行播放。
此外，所述子母画面处理器4还过滤出对应两个选择频道的音频数据，并将其中一组音频数据传送至第一音频解码器6进行解码，经过解码后的数字信号被传送至第一蓝牙传输器8，第一蓝牙传输器8将所述数字信号转变成用户可识别的模拟信号，用户可以通过一个蓝牙耳麦接收第一蓝牙传输器8传送的模拟信号以实现立体双声道。
另一组音频数据传送至第二音频解码器7进行解码，经过解码后的数字信号的数字信号被传送至第二蓝牙传输器9，第二蓝牙传输器9将所述数字信号转变成用户可识别的模拟信号，另一用户可以通过另一个蓝牙耳麦接收第二蓝牙传输器9传送的模拟信号以实现立体双声道。
通过采用上述串连连接着的第一音频解码器6及第一蓝牙传输器8、第二音频解码器7及第二蓝牙传输器9分别将对应用户选择的两个频道的音频数据转换为用户可识别的声音，从而实现蓝牙子母立体双声道。
