请参照图2，本发明第二实施例所揭露的视频处理系统10包括第一视频 模块110和第二视频模块120。第一视频模块110电性设置有处理器、视频输入接口、音频数据输出接口以及音频数据输入接口111，且第一视频模块110电性连接于一内部信号源，此内部信号源可以是电视信号源、互联网的信号源或本地端下载的信号源，其中第一视频模块110通过处理器将来自内部信号源的音视频数据进行处理，例如将音视频数据中的视频数据转变为HDMI的数据格式后，再输出至第二视频模块120；或者是将音视频数据中的音频数据转变为I2S的数据格式后，再通过音频数据输出接口传送至一音频系统进行播放。

请参照图3，为本发明视频处理系统的第三实施例的方块图。本发明所揭露的第三实施例与第二实施例在结构或组成组件上大致相同，两者间的差异在于，本发明第三实施例所揭露的视频处理系统在第二视频模块120还包括数据格式转换桥片125，其中数据格式转换桥片125分别电性连接于显示 屏驱动模块123、内部视频处理子模块121的运动补偿帧率转换器1212和外部视频处理子模块122的视频处理器1222。数据格式转换桥片125用以接收运动补偿帧率转换器1212处理后的内部视频数据或者是视频处理器1222处理后的外部视频数据，并且转换处理后的内部视频数据的数据格式或处理后的外部视频数据的数据格式，例如从HDMI的数据格式转换为微型低电压差分信号(Mini Low Voltage Differential Signaling,MiniLVDS)，以便于让处理后的内部视频数据或处理后的外部视频数据可以顺利的传送至显示屏。
在视频处理系统的应用上，适于配置在多媒体播放设备中，用以对多媒体播放设备所接收到的音视频数据进行优化处理，尤其是对于其中的视频数据的优化处理。以下通过一具体实施方式对本发明所揭露的视频处理系统的具体应用作举例说明。
请参照图3，本发明具体实施例所揭露的多媒体播放设备1除了上述的视频处理系统10(例如第三实施例所揭露的视频处理系统)外，还包括显示屏20以及可选择性配置的音频系统30，显示屏20与音频系统30可以是但并不局限于多媒体播放设备1本身所具有的音频和/或视频播放装置，例如在多媒体播放设备1为智能电视的场景下；或者是以可拆卸的形式外接于多媒体播放设备1的音频和/或视频播放装置，例如在多媒体播放设备1为投影机的场景下。在本实施例中，是以多媒体播放设备1为智能电视作为举例说明，但并不以此为限。
显示屏20电性连接于第二视频模块120的显示屏驱动模块123，用以接收显示屏驱动模块123产生的控制信号，并根据控制信号呈现相应的视频影像。
音频系统30电性连接于第一视频模块110，例如通过I2C总线以及I2S总线电性连接于第一视频模块110，并且自第一视频模块110接收来自外部信号源的外部音频数据或者是来自内部信号源的内部音频数据，然后进行播放。
其中，当内部视频数据由第一视频模块110播放时，第一视频模块110可以根据实际情况对内部视频数据或内部音频数据的数据格式进行转换，例 如将内部视频数据转变为HDMI格式后，输出至第二视频模块120，以及将内部音频数据转变为I2S格式后，发送给音频系统30进行播放。
接着，通过第二视频模块120的内部数据接收器1211传送此内部视频数据至运动补偿帧率转换器1212进行高分辨率与高分辨率处理，然后再通过数据格式转换桥片125转变为显示屏20能接收的数据格式后，再经由显示屏驱动模块123传送给显示屏20进行视频影像的显示。
并且，当视频数据是来自于外部信号源时，通过第二视频模块120的外部数据接收器1212接收外部视频数据，并且将外部视频数据传送给视频处理器1222进行相应的处理程序，例如运动检测、运动补偿、帧频转换等处理程序。接着，再通过数据格式转换桥片125转变为显示屏20能接收的数据格式，例如MiniLVDS，然后通过显示屏驱动模块123传送给显示屏20进行视频影像的显示。而来自于外部信号源的外部音频数据，在第二视频模块120中输出SPDIF/I2S格式的外部音频数据至第一视频模块110，再通过第一视频模块110输出I2S格式的外部音频数据至音频系统30进行播放。
此外，在第二视频模块120通过外部数据接收器1221接收外部视频数据的应用场景中，若用户按动遥控器或按键对视频处理系统10进行控制时，通过第一视频模块110产生相应的选单数据，并且通过内部数据接收器1211传送至第二视频模块120，让选单数据在第二视频模块120中与外部视频数据进行叠加，并通过数据格式的转变后，转变为显示屏20能接收的数据格式，如MiniLVDS，最后再通过显示屏驱动模块123传送给显示屏20进行视频影像的显示。
