具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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。
本发明实施例所揭露的音视频播放设备和/或音视频输出设备，用以传送视频信号至显示屏，其中音视频播放设备可以是但并不局限于电视机，例如智能电视，而音视频输出设备可以是DVD播放器或机顶盒等外接于音视频播放设备的影音装置，以上仅用以举例说明，但并不以此为限。
请参照图1，本发明第一实施例所揭露的音视频播放设备10耦接有主信 号源20、音频系统30以及显示屏40，其中主信号源20可以是但并不局限于电视信号源、来自互联网的信号源或本地端下载的信号源，而音频系统30与显示屏40可以是但并不局限于音视频播放设备10本身所具有的多媒体装置或者是以可拆卸的形式外接于音视频播放设备10的多媒体装置。音视频播放设备10包括处理器110、视频格式转换桥片120以及运动补偿帧率转换器130，其中处理器110通过I2C(Inter－Integrated Circuit，内部整合电路)总线分别耦接于视频格式转换桥片120与运动补偿帧率转换器130。并且，在音视频播放设备10内还配置有以太网模块140、无线通信模块150、电源管理模块160以及存储器模块170，分别耦接于处理器110。
在本发明中，处理器110为主频与寄存器位数相较于一般处理器高的处理器，例如，若一般处理器为32位、主频1.2GHz，则处理器110可以是64位、主频2～2.5GHz的处理器，此为相对值，只要在性能指标上明显高于一般处理器的性能者(即所谓的高性能处理器)，皆适用于本发明实施例中作为音视频播放设备10内的处理器110。
处理器110耦接于音视频播放设备10的主信号源20，并且通过I2S(Inter—IC Sound)音频总线(又称集成电路内置音频总线)耦接于音频系统30，用以接收主信号源20的音视频信号，例如，从配置于音视频播放设备10内，并且耦接于处理器110的以太网模块140、无线通信模块150以及存储器模块170的其中之一所发送至处理器110的音视频信号；并且，处理器110还用以将所接收的音视频信号中的音频信号传送至音频系统30以及将音视频信号中的视频信号传送至视频格式转换桥片120。其中，主信号源20包括：通过以太网模块140或无线通信模块150等无线或有线通信模式所接收的音视频信号；或者是直接从存储器模块170内读取的音视频数据等，直接由音视频播放设备10本身所提供的音视频信号。
此外，处理器110上电性设置有第一视频格式输出接口111以及处理模块112，其中处理模块112包括中央处理单元(central processing unit,CPU)111和/或图形处理单元(graphic processing unit,GPU)。而第一视频格式输出接口111可以是但并不局限于移动终端高清影音标准接口(mobile high-definition link,MHL；以下简称MHL接口)、HDMI接口、低压差分信号(Low Voltage Differential Signaling,LVDS)接口、DP接口(display  port)、EDP接口(Embedded DisplayPort)、MIPI DSI接口(Mobile Industry Processor Interface-Display Serial Interface，移动行业处理器及显示器串行接口)及其组合其中之一，处理器110即通过第一视频格式输出接口111耦接于视频格式转换桥片120上相应的接口。
视频格式转换桥片120上电性设置有第一视频格式输入接口121、微控制单元(micro control unit,MCU)122以及第二视频格式输出接口123。第一视频格式输入接口121耦接于处理器110的第一视频格式输出接口111，用以从处理器110接收主信号源20中的视频信号。而第二视频格式输出接口123耦接于运动补偿帧率转换器130上电性设置的第二视频格式输入接口131，用以在视频格式转换桥片120对视频信号进行数据格式的转换后，将转换后的视频信号传送至运动补偿帧率转换器130。
其中，视频格式转换桥片120的第一视频格式输入接口121的数据格式与处理器110的第一视频格式输出接口111的数据格式相同，例如同样为HDMI数据格式；视频格式转换桥片120的第二视频格式输出接口123的数据格式与处理器110的第一视频格式输出接口111的数据格式相异，例如为V-by-One数据格式。可以理解的是，由于视频格式转换桥片120的第二视频格式输出接口123与运动补偿帧率转换器130的第二视频格式输入接口131为数据格式相对应的视频信号输出接口与视频信号输入接口，因此，在本实施例中，运动补偿帧率转换器130的第二视频格式输入接口131的数据格式同样为V-by-One数据格式。
运动补偿帧率转换器130除了耦接于视频格式转换桥片120外，还耦接于显示屏40，用以从视频格式转换桥片120接收转换后的视频信号，并且基于运动检测与运动补偿(motion estimation and motion compensation,MEMC)原理对转换后的视频信号进行帧频转换(frame rate conversion,FRC)，从而将转换后的视频信号处理为高分辨率和高帧率视频信号，例如从普通60Hz刷新率的视频内容提升到120Hz或者240Hz刷新率的视频内容，然后将此高分辨率和高帧率视频信号传送至显示屏40进行播放，从而提高运动画面的清晰程度。
以下通过一具体实施方式对本发明第一实施例所揭露的音视频播放设备 10的运作方式作举例说明。
当音视频播放设备10的处理器110从主信号源20接收到音视频信号后，通过I2S音频总线将此音视频信号中的音频信号传送至音频系统30；以及通过第一视频格式输出接口111将此音视频信号中的视频信号传送至视频格式转换桥片120，在此传送过程中，处理器110根据实际需求选择性地将视频信号的数据格式转换为适用于第一视频格式输出接口111的数据格式，例如HDMI，然后再通过第一视频格式输出接口111传送至视频格式转换桥片120。
视频格式转换桥片120通过第一视频格式输入接口121接收上述视频信号后，将视频信号的数据格式从HDMI数据格式转换为V-by-One数据格式，然后通过第二视频格式输出接口123将转换后的视频信号传送至运动补偿帧率转换器130。
接着，在通过第二视频格式输入接口131接收转换后的视频信号后，运动补偿帧率转换器130对转换后的视频信号进行运动检测、运动补偿以及帧频转换，使转换后的视频信号被处理为高分辨率和高帧率视频信号。然后，将此高分辨率和高帧率视频信号传送至显示屏40进行播放，从而在显示屏40上呈现出高清晰度画面。
因此，在本发明的音视频播放设备中，通过处理器的性能指标明显高于一般处理器的配置方式，让音视频播放设备具有处理大型软件的能力，例如大型游戏或其他高功耗的软件等。并且，通过视频格式转换桥片对视频信号进行数据格式转换，让处理器所接收的视频信号可以在显示屏上进行播放；以及通过运动补偿帧率转换器对转换后的视频信号进行优化，而提供高分辨率和高帧率视频信号至显示屏，从而提升显示画面的质量，同时增进用户体验。
此外，在本实施例中，视频格式转换桥片120上还可以选择性的电性设置有外部音视频输入接口124，用以在音视频播放设备20外接有其他音视频相关设备的情况下，可以通过外部音视频输入接口124接收外部音视频信号，其运作方式详述如下。
如图2所示，为本发明第二实施例所揭露的音视频播放设备10的方块图。本发明所揭露的第二实施例与第一实施例在系统架构上大致相同，两者间的 差异在于，在本发明第二实施例所揭露的音视频播放设备10中，视频格式转换桥片120上还电性设置有外部音视频输入接口124以及音频输出接口125，其中外部音视频输入接口124用以耦接于DVD播放器或机顶盒等音视频输出设备的外部信号源，以便于从音视频输出设备接收外部信号源的音视频信号。因此，外部音视频输入接口124的数据格式可以是但并不局限于MHL接口、HDMI接口、LVDS接口、DP接口、EDP接口或MIPI DSI接口等数据格式，或者是上述数据格式的组合。而音频输出接口125通过I2S总线耦接于处理器110，用以在视频格式转换桥片120将所接收的外部信号源的音视频信号中的音频信号进行格式转换后，将转换后的音频信号传送至处理器110，以便于提供至音频系统30进行播放。例如，将HDMI数据格式的音频信号转换为I2S数据格式的音视频信号后，通过I2S总线将其传送至处理器110；或者是在某些情况下，先将HDMI数据格式的音频信号转换为SPDIF数据格式，然后再从SPDIF数据格式转换为I2S数据格式后，接着再传送至处理器110。
此外，视频格式转换桥片120还将外部信号源的音视频信号中的视频信号进行数据格式的转换，例如，从HDMI数据格式转换为V-by-One数据格式，使其符合第二视频格式输出接口123的输出格式，以便于将音视频信号中经转换的视频信号传送至运动补偿帧率转换器130进行高分辨率和/或高帧率处理。例如，若此视频信号的分辨率已经是最高分辨率，在此情况下不进行分辨率的处理，反之，如果不是最高分辨率，则将其处理为最高分辨率。例如，当输入的视频信号具有4K*2K分辨率，则不处理；若输入的视频信号仅具有1080P的分辨率，则将其处理为4K*2K分辨率，然后再传送至显示屏40。
因此，在本发明第二实施例所揭露的音视频播放设备中，视频格式转换桥片120可选择性的通过第一视频格式输入接口121接收来自处理器110的内部视频信号；或者是通过外部音视频输入接口124接收来自音视频播放设备10外的外部音视频信号，并且根据信号源不同而选择相应的处理模式。
其中，当视频信号来自主信号源20时，视频格式转换桥片120所采用的处理模式与第一实施例所揭露的相同，在此不再赘述。当信号源为来自DVD播放器或机顶盒等外接的音视频输出设备时，视频格式转换桥片120通过外部音视频输入接口124接收外部信号源的音视频信号，并且，视频格式转换桥片120将此音视频信号的数据格式进行转换，例如将音视频信号中的音频 信号从HDMI数据格式转换为I2S数据格式，然后传送至处理器110，以便于提供至音频系统30播放；以及将音视频信号中的视频信号从HDMI数据格式转换为V-by-One数据格式，然后传送至运动补偿帧率转换器130，并且通过运动补偿帧率转换器130将转换后的视频信号处理成高分辨率和高帧率视频信号后，再传送至显示屏40，从而在外接有DVD播放器或机顶盒等音视频输出设备时，同样能在显示屏40上呈现高清晰度画面。
此外，在本发明的第二实施例中，视频格式转换桥片120上还可以选择性的电性设置有屏幕显示选单(on screen display,OSD)功能模块126，其通过I2C总线与处理器110之间进行通讯，用以根据处理器110的指令产生相应的屏幕显示选单数据。因此，在需要使用菜单的场景下，处理器110根据外部的输入指令控制视频格式转换桥片120的屏幕显示选单功能模块126产生屏幕显示选单数据，例如在本发明的音视频播放设备10为电视机的场景中，通过遥控器传送出要求显示控制菜单的功能指令至处理器110，处理器110即依据此功能指令通知视频格式转换桥片120的屏幕显示选单功能模块126产生相应的屏幕显示选单数据，并且通过视频格式转换桥片120将屏幕显示选单数据与外部视频信号进行叠加，并且将叠加后的外部视频信号进行数据格式的转换。之后再传送到运动补偿帧率转换器130处理为高分辨率和高帧率视频信号，以便于在显示屏40上同时呈现高清晰度画面与控制菜单。
值得说明的是，在本发明的音视频播放设备中，若处理器与视频格式转换桥片的距离较近，不需要长距离的信号线走线的情况下；或者是在不使用运动补偿帧率转换器的情况下，可以将运动补偿帧率转换器的功能关闭，或者是省略运动补偿帧率转换器的配置。
如图3所示，在本发明所揭露的第三实施例中，音视频播放设备10包括处理器110以及视频格式转换桥片120。处理器110耦接于主信号源20，并且通过I2S音频总线耦接于音频系统30以及通过I2C总线耦接于视频格式转换桥片120，用以接收主信号源20的音频信号和/或通过视频格式转换桥片120输入的外部信号源的音频信号，并将主信号源20和/或外部信号源的音频信号传送至音频系统30，以及将主信号源的视频信号传送至视频格式转换桥片120。
视频格式转换桥片120上电性设置有第一视频格式输入接口121、微控制单元122、第二视频格式输出接口123、外部音视频输入接口124以及音频输出接口125。其中，第一视频格式输入接口121耦接于处理器110的第一视频格式输出接口111，用以从处理器110接收主信号源20中的视频信号；第二视频格式输出接口123耦接于显示屏40，用以在视频格式转换桥片120对视频信号进行数据格式的转换后，将转换后的视频信号传送至显示屏40；外部音视频输入接口124用以耦接于DVD播放器或机顶盒等音视频输出设备的外部信号源，以便于从音视频输出设备接收外部信号源的音视频信号；而音频输出接口125通过I2S总线耦接于处理器110，用以在视频格式转换桥片120将所接收的外部信号源的音视频信号中的音频信号进行格式转换后，将转换后的音频信号传送至处理器110，以便于提供至音频系统30进行播放。
此外，在本发明所揭露的第三实施例中，屏幕显示选单功能模块可以是耦接于视频格式转换桥片120或者是处理器110。当屏幕显示选单功能模块耦接于视频格式转换桥片120时，其整体架构与功能与第二实施例中所述相同，在此不再赘述。
在本发明音视频播放设备10的第三实施例中，当屏幕显示选单功能模块180耦接于处理器110时，处理器110上还电性设置有选单数据输出接口113，且视频格式转换桥片120上还电性设置有选单数据输入接口127。选单数据输出接口113与选单数据输入接口127相互耦接，且两者可以是数据格式相互对应的接口或者是数据格式相异的接口，其中，若选单数据输出接口113与选单数据输入接口127的数据格式相异，那么在处理器110与视频格式转换桥片120之间还耦接有选单数据格式转换桥片190，用以将屏幕显示选单数据的数据格式转换为适于视频格式转换桥片120接收的数据格式。
因此，在操作上，当处理器接收到要求显示控制菜单的功能指令后，处理器110即依据此功能指令控制屏幕显示选单功能模块180产生相应的屏幕显示选单数据，然后通过选单数据输出接口113与选单数据输入接口127直接的传送至视频格式转换桥片120；或者是先通过选单数据格式转换桥片190将屏幕显示选单数据的数据格式进行转换后，再传送至视频格式转换桥片120，以便于通过视频格式转换桥片120将屏幕显示选单数据与外部信号源的视频信号进行叠加，并且将叠加后的视频信号进行数据格式的转换。之后再 传送到显示屏40进行播放。
本领域普通技术人员可以理解：实现上述方法实施例的全部或部分步骤可以通过程序指令相关的硬件来完成，前述的程序可以存储于一计算机可读取存储介质中，该程序在执行时，执行包括上述方法实施例的步骤；而前述的存储介质包括：ROM、RAM、磁碟或者光盘等各种可以存储程序代码的介质。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
