以下结合附图，详细说明本发明各实施例提供的技术方案。
本发明实施例所揭露的音视频播放设备，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，其中音视频播放设备还可以外接有音视频输出设备，例如DVD播放器或机顶盒等外接于音视频播放设备的影音装置，并且以音视频输出设备作为外部信号源，而从音视频输出设备接收外部音频号和外部视频信号，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包括系统处理器110、视频处理器120以及视频格式转换桥片130。
系统处理器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，则系统处理器110可以是64位、主频2～2.5GHz的处理器，此为相对值，因此，并不以此为限。系统处理器 110分别耦接于视频处理器120与视频格式转换桥片130，且系统处理器110具有屏幕显示选单功能模块111，用以产生屏幕显示选单数据。
视频处理器120分别耦接于系统处理器110与外部信号源，用以接收屏幕显示选单数据和来自外部信号源的外部视频信号，并且将屏幕显示选单数据与外部视频信号进行叠加，以及将叠加后的外部视频信号传送至视频格式转换桥片130。其中，外部信号源可以是但并不局限于DVD播放器或机顶盒等外接于音视频播放设备10的音视频输出设备。
视频格式转换桥片130耦接于视频处理器120与显示屏20，用以接收及转换叠加后的外部视频信号的数据格式，并且将转换后的外部视频信号传送至显示屏20。
在应用上，当输入音视频播放设备10的音视频信号是来自于DVD播放器或机顶盒等音视频输出设备的外部信号源时，音视频播放设备10通过视频处理器120耦接于此外部信号源，并且从外部信号源接收音视频信号。在接收来自外部信号源的外部音视频信号后，视频处理器120可以是直接地对外部音视频信号进行后续处理，或者是根据使用需求从系统处理器110接收与此音视频信号相对应的屏幕显示选单数据，并且将屏幕显示选单数据与此音视频信号中的视频信号(也就是来自外部信号源的外部视频信号)进行叠加，然后将叠加有屏幕显示选单数据的外部视频信号传送至视频格式转换桥片130。
接着，视频格式转换桥片130对叠加后的外部视频信号(也就是叠加有屏幕显示选单数据的外部视频信号)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，使其符合显示屏的接收格式，以便于在显示屏20上播放。
因此，本发明实施例提供的音视频播放设备可以通过视频处理器接收来自外部信号源的音视频信号，并且，通过系统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，让系统处理器所接收的主视频信号和视频处理器所接收的外部视频信号可以在显示屏上进行播放，从而提升显示画面的质量，同时增 进用户体验。
请参照图2，本发明第二实施例所揭露的音视频播放设备10耦接有主信号源30、音频系统40以及显示屏20，其中主信号源30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40与显示屏20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包括系统处理器110、视频处理器120、视频格式转换桥片130以及运动补偿帧率转换器140，其中系统处理器110通过I2C(Inter-Integrated Circuit，内部整合电路)总线分别耦接于视频处理器120、视频格式转换桥片130与运动补偿帧率转换器140。并且，在音视频播放设备10内还配置有以太网模块150、有线和/或无线通信模块160(例如蓝牙模块、wifi模块、2.4G通信模块等)、电源管理模块170、存储器模块180及其组合其中之一，分别耦接于系统处理器110。
在本发明中，系统处理器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，则系统处理器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内的系统处理器110。
系统处理器110耦接于音视频播放设备10的主信号源30，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40，用以接收主信号源30的音视频信号，例如，从配置于音视频播放设备10内的以太网模块150与有线和/或无线通信模块160其中之一发送至系统处理器110的音视频信号或者是系统处理器110从存储器模块180内读取的音视频数据。并且，系统处理器110还用以将来自主信号源的主音频信号(即所接收的音视频信号中的音频信号)传送至音频系统40以及将来自主信号源的主视频信号(也就是主信号源的音视频信号中的视频信号)传送至视频处理器120。其中，主信号源30包括：通过以太网模块150或有线和/或无线通信模块160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180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，系统处理器110上电性设置有视频信号输出接口112、处理模块113以及屏幕显示选单功能模块111。其中，处理模块113包括中央处理单元(central processing unit,CPU)和/或图形处理单元(graphic processing unit,GPU)。而视频信号输出接口112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；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)、逻辑门电路接口(Transistor-Transistor Logic,TTL；简称TTL接口)及其组合其中之一，系统处理器110即通过视频信号输出接口112耦接于视频格式转换桥片130上相应的接口。
屏幕显示选单功能模块111用以根据系统处理器110所接收到的操作指令产生相应的屏幕显示选单数据。例如，在需要使用菜单的场景下，系统处理器110根据外部的输入指令控制屏幕显示选单功能模块111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系统处理器110，系统处理器110的处理模块113即依据此功能指令通知屏幕显示选单功能模块111产生相应的屏幕显示选单数据，并且传送至视频处理器120；或者通过系统处理器110将其与主视频信号进行叠加，然后再将叠加有屏幕显示选单数据的主视频信号传送至视频处理器120。
视频处理器120耦接于系统处理器110，并且在DVD播放器或机顶盒等音视频输出设备外接于本发明实施例的音视频播放设备10时，耦接于这些外接设备，并且以这些音视频输出设备作为外部信号源。视频处理器120上电性设置有视频信号输入接口121、选单数据输入接口122与外部音视频输入接口123。视频信号输入接口121耦接于系统处理器110的视频信号输出接口112，用以从系统处理器110接收来自主信号源30的主视频信号；选单数据输入接口122耦接于屏幕显示选单功能模块111，用以接收屏幕显示选单数据；而外部音视频输入接口123用以耦接于外部信号源，以便于接收外 部信号源输入的音视频信号。因此，外部音视频输入接口122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接口或TTL接口等不同数据格式的接口，或者是上述数据格式的组合。
其中，视频处理器120所接收的主视频信号可以是但并不局限于叠加有屏幕显示选单数据的主视频信号，并且当视频处理器120从外部信号源接收音视频信号后，视频处理器120可以先将屏幕显示选单数据与来自外部信源的外部视频信号进行叠加，然后再将叠加后的外部视频信号，也就是叠加有屏幕显示选单数据的外部视频信号，传送至视频格式转换桥片130。
视频格式转换桥片130分别耦接于系统处理器110、视频处理器120与运动补偿帧率转换器140，且视频格式转换桥片130上电性设置有第一视频格式输入接口131、第二视频格式输出接口132、音频输出接口133以及微控制单元(micro control unit,MCU)134。第一视频格式输入接口131耦接于视频处理器120，用以从视频处理器120接收主视频信号或外部视频信号，其中主视频信号和外部视频信号可以是分别叠加有屏幕显示选单数据的主视频信号和外部视频信号。第二视频格式输出接口132耦接于电性设置于运动补偿帧率转换器140上的第二视频格式输入接口141，用以在视频格式转换桥片120对主视频信号和外部视频信号进行数据格式的转换后，将转换后的主视频信号或外部视频信号传送至运动补偿帧率转换器140。
其中，视频格式转换桥片130的第一视频格式输入接口131的数据格式与视频处理器120的视频信号输入接口121和外部音视频输入接口122的数据格式相同，例如同样为HDMI数据格式；而视频格式转换桥片130的第二视频格式输出接口132的数据格式与第一视频格式输入接口131的数据格式相异，例如为V-by-One数据格式。可以理解的是，视频格式转换桥片130的第二视频格式输出接口132与运动补偿帧率转换器140的第二视频格式输入接口141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140的第二视频格式输入接口141的数据格式同样为V-by-One数据格式。
此外，视频格式转换桥片130的音频输出接口133通过I2S总线耦接于 系统处理器110，用以在视频格式转换桥片130将来自外部信号源的外部音频信号进行格式转换后，将转换后的外部音频信号传送至系统处理器110，以便于提供至音频系统40进行播放。例如，将HDMI数据格式的外部音频信号转换为I2S数据格式的外部音频信号后，通过I2S总线将其传送至系统处理器110；或者是在某些情况下，先将HDMI数据格式的外部音频信号转换为SPDIF数据格式，然后再从SPDIF数据格式转换为I2S数据格式后，接着再传送至系统处理器110。
运动补偿帧率转换器140分别耦接于视频格式转换桥片130与显示屏20，用以从视频格式转换桥片130接收转换后的主视频信号或转换后的外部视频信号，并且基于运动检测与运动补偿(motion estimation and motion compensation,MEMC)原理对转换后的主视频信号或转换后的外部视频信号进行帧频转换(frame rate conversion,FRC)，从而将转换后的主视频信号或转换后的外部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20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二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的系统处理器110从主信号源30接收到音视频信号后，通过I2S音频总线将来自主信号源30的主音频信号传送至音频系统40；以及通过视频信号输出接口112将此来自主信号源30的主视频信号传送至视频处理器120，在此过程中，系统处理器110还根据实际需求选择性地将主视频信号的数据格式转换为适用于视频信号输出接口112的数据格式，例如HDMI，然后再通过视频信号输出接口112传送至视频处理器120。同时，系统处理器110也可以根据所接收到的外部操作指令而通过屏幕显示选单功能模块111产生相应的屏幕显示选单数据，并且将此屏幕显示选单数据传送至视频处理器120。
视频处理器120通过视频信号输入接口121接收上述的主视频信号与屏幕显示选单数据后，对屏幕显示选单数据与主视频信号进行叠加，然后将叠 加后的主视频信号传送至视频格式转换桥片130。值得说明的是，上述屏幕显示选单数据与主视频信号的叠加操作，也可以是在系统处理器中完成，然后再传送至视频处理器120，此时视频处理器120可以直接将叠加有屏幕显示选单数据的主视频信号传送至视频格式转换桥片130，以进行下一阶段的处理程序。
接着，视频格式转换桥片130通过第一视频格式输入接口131接收上述的主视频信号后，将主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132将转换后的主视频信号传送至运动补偿帧率转换器150。然后，通过运动补偿帧率转换器140对转换后的主视频信号进行运动检测、运动补偿以及帧频转换，使转换后的主视频信号被处理为高分辨率和高帧率视频信号。最后，将此高分辨率和高帧率视频信号传送至显示屏20进行播放，从而在显示屏20上呈现出高清晰度画面。
此外，当输入音视频播放设备10的音视频信号是来自于DVD播放器或机顶盒等音视频输出设备的外部信号源时，此外部信号源通过外部音视频输入接口123耦接于视频处理器120，以便于通过外部音视频输入接口123将音视频信号输入至视频处理器120。在接收外部信号源的音视频信号后，视频处理器120根据需求从系统处理器110接收与此音视频信号相对应的屏幕显示选单数据，并且将屏幕显示选单数据与此音视频信号中的视频信号(也就是来自外部信号源的外部视频信号)进行叠加，然后将来自外部信号源的外部音频信号以及叠加有屏幕显示选单数据的外部视频信号传送至视频格式转换桥片130。
接着，视频格式转换桥片130通过音频输出接口133将其中的外部音频信号传送至系统处理器110，再通过系统处理器110提供至音频系统40进行播放。而叠加有屏幕显示选单数据的外部视频信号通过视频格式转换桥片130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132的输出格式，然后再通过第二视频格式输出接口132将转换后的外部视频信号传送至运动补偿帧率转换器140，以便于进行高分辨率和/或高帧率处理。例如，若此外部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，当输入的外部视频信号具有4K*2K分辨率，则不处理；若输入的外部视频信号仅具有1080P的分辨率，则将其处理为4K*2K分辨率。
因此，本发明实施例提供的音视频播放设备可选择性的通过系统处理器接收来自主信号源的音视频信号；或者是通过视频处理器接收来自外部信号源的音视频信号，并且根据信号源的不同而选择相应的处理模式。同时，在本发明实施例提供的音视频播放设备中，通过系统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，让系统处理器所接收的主视频信号和视频处理器所接收的外部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主视频信号或外部视频信号进行优化，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。
值得说明的是，在本发明实施例的音视频播放设备中，若系统处理器、视频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包括系统处理器110、视频处理器120以及视频格式转换桥片130。视频格式转换桥片130的第二视频格式输出接口132耦接于显示屏20，并且在视频格式转换桥片130对叠加有屏幕显示选单数据的外部视频信号进行数据格式的转换后，即通过第二视频格式输出接口132将转换后的外部视频信号传送至显示屏20进行播放，而省略了运动补偿帧率转换器的配置。
此外，如图4所示，为本发明音视频播放设备的第四实施例的方块图。本发明第四实施例与第二实施例在系统架构上大致相同，两者间的差异在于，本发明第四实施例所揭露的音视频播放设备10还包括选单数据格式转换桥片150，耦接于系统处理器110与视频处理器120之间，用以将屏幕显示选单数据的数据格式转换为适于视频处理器120接收的数据格式。
因此，在操作上，当系统处理器110接收到要求显示控制菜单的操作指 令后，系统处理器110即依据此操作指令控制屏幕显示选单功能模块111产生相应的屏幕显示选单数据，然后传送至视频处理器120；或者是先通过选单数据格式转换桥片150将屏幕显示选单数据的数据格式进行转换后，再传送至视频处理器120，以便于通过视频处理器120将屏幕显示选单数据与外部视频信号或主视频信号进行叠加，并且将叠加后的外部视频信号或主视频信号传送到视频格式转换桥片130进行数据格式的转换。最终让运动补偿帧率转换器140能顺利接收到转换后的外部视频信号或主视频信号，以便于进行高分辨率和/或高帧率处理。
以上所描述的装置实施例仅仅是示意性的，其中所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。本领域普通技术人员在不付出创造性的劳动的情况下，即可以理解并实施。
图5为本发明音视频播放方法的第一实施例的流程图，如图5所示，该方法包括如下步骤：
步骤101、产生屏幕显示选单数据。
步骤102、接收来自外部信号源的外部视频信号，并将所述屏幕显示选单数据与所述外部视频信号进行叠加。
步骤103、转换所述叠加后的外部视频信号的数据格式。
步骤104、显示所述转换后的外部视频信号。
本实施例所提供的方法中的各步骤的执行主体以及实现方式可以参考图1所示实施例中的描述。
本实施例中，当输入音视频播放设备的音视频信号是来自于DVD播放器或机顶盒等音视频输出设备的外部信号源时，外部音视频信号中可以包括外部视频信号，也可以包含外部音频信号。
在接收来自外部信号源的外部音视频信号后，可以直接对外部音视频信号进行后续处理，或者是根据使用需求将与此音视频信号相对应的屏幕显示选单数据与此音视频信号中的视频信号即外部视频信号进行叠加，然后对叠加有屏幕显示选单数据的外部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，使其符合显示屏的接收格式，以便于在显示屏上播放。
本发明实施例中，结合图1-图4所示的音视频播放设备的结构组成，通过系统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，通过对视频信号进行数据格式转换，让系统处理器所接收的主视频信号和视频处理器所接收的外部视频信号可以在显示屏上进行播放，从而提升显示画面的质量，同时增进用户体验。
可选的，在步骤101产生屏幕显示选单数据之后，还可以包括：对所述屏幕显示选单数据进行格式转换的步骤。
实际应用中，系统处理器可以根据接收到的操作指令产生相应的屏幕显示选单数据。例如，在需要使用菜单的场景下，系统处理器根据外部的输入指令控制产生屏幕显示选单数据，例如在本发明的音视频播放设备为电视机的场景中，通过遥控器传送出要求显示控制菜单的功能指令至系统处理器，系统处理器依据此功能指令控制产生相应的屏幕显示选单数据。
结合图1或图2所示实施例，屏幕显示选单数据被发送至视频处理器，为了使得产生的屏幕显示选单数据与视频处理器的处理格式相适应，可以将屏幕显示选单数据的数据格式转换为适于视频处理器接收的数据格式。
可选的，步骤104中显示所述转换后的外部视频信号之前，还可以包括：
处理所述转换后的外部视频信号为高分辨率和高帧率视频信号。则显示所述转换后的外部视频信号，适应性变为：显示所述高分辨率和高帧率视频信号。
具体来说，可以基于运动检测与运动补偿(motion estimation and motion compensation,MEMC)原理对转换后的外部视频信号进行帧频转换(frame rate conversion,FRC)，从而将转换后的外部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20进行播放，从而提高运动画面的清晰程度。
前述描述中说明，外部音视频信号中除了外部视频信号外，还可以包括外部音频信号，因此，可选的，本实施例提供的音视频播放方法还可以包括：
接收来自外部信号源的外部音频信号；
对所述外部音频信号进行数据格式转换；
播放转换后的外部音频信号。
当接收到外部音频信号后，为了使得该外部音频信号适于通过音视频播放设备所连接的音频系统的播放要求，需要对外部音频信号进行格式转换，将转换后的外部音频信号提供至音频系统进行播放。例如，将HDMI数据格式的外部音频信号转换为I2S数据格式的外部音频信号后，通过I2S总线将其传送至系统处理器，由系统处理器提供至音频系统进行播放；或者是在某些情况下，先将HDMI数据格式的外部音频信号转换为SPDIF数据格式，然后再从SPDIF数据格式转换为I2S数据格式后，接着再传送至系统处理器，由系统处理器提供至音频系统进行播放。
实际应用中，音视频播放设备除了可以接收外部信号源的外部音视频信号外，其信号源还可以是主信号源，其中包括主视频信号和主音频信号。主信号源和外部信号源可以是同时存在的，也可以是择一存在的，针对这两种不同的存在情况，音视频播放设备所处理的信号是不同的，比如为主视频信号和/或外部视频信号，视实际应用情况而定，不做具体限定。下面结合图6对来自主信号源的主音视频信号进行播放过程的说明。具体的处理过程可以结合图1-图4所示实施例理解。
图6为本发明音视频播放方法的第二实施例的流程图，如图6所示，在图5所示实施例产生屏幕显示选单数据的基础上，所述方法包括：
步骤201、接收来自主信号源的主视频信号。
步骤202、叠加屏幕显示选单数据与所述主视频信号。
步骤203、转换所述叠加后的主视频信号的数据格式。
步骤204、显示所述转换后的主视频信号。
其中，主信号源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。
当主信号源中包含主音频信号时，该方法还包括：接收来自所述主信号源的主音频信号；通过音频系统播放该主音频信号。
当主信号源中包含主视频信号时，将叠加屏幕显示选单数据与主视频信 号叠加，并转换叠加后的主视频信号的数据格式，使其适于显示屏的显示。
当然，如果此时除了主信号源外，还接收到来自外部信号源的外部视频信号，可以分别对外部视频信号和主视频信号分别进行上述叠加屏幕显示选单数据以及格式转换的处理。
可选的，步骤204中显示所述转换后的主视频信号之前，还包括：
处理所述转换后的主视频信号为高分辨率和高帧率视频信号。则相应的，显示所述转换后的主视频信号，包括：显示所述高分辨率和高帧率视频信号。
基于运动检测与运动补偿(motion estimation and motion compensation,MEMC)原理对转换后的主视频信号进行帧频转换(frame rate conversion,FRC)，从而将转换后的主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20进行播放，从而提高运动画面的清晰程度。
另外，本发明实施例还提供一种音视频播放设备，包括：处理器和存储器，所述存储器中存储有程序，所述处理器用于调用所述存储器中存储的所述程序，以执行如图5或图6所述方法实施例中的步骤。
另外，本发明实施例还提供一种在其上记录有用于执行如图5或图6所述方法的程序的计算机可读记录介质.
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到各实施方式可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件。基于这样的理解，上述技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品可以存储在计算机可读存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行各个实施例或者实施例的某些部分所述的方法。
最后应说明的是：以上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精神和范围。
