现有的音视频播放设备(例如智能电视)对于执行音视频播放功能所采用的方案中，由于其处理器的处理能力较低，仅能满足播放视频或玩小型的游戏的使用需求。但是对于执行大型游戏的使用需求而言，其对于大型游戏的处理能力就远不能满足，所以游戏爱好者若是想通过一般的音视频播放设备执行大型游戏的操作，必需额外购买游戏机才能执行，例如微软的XBOX ONE或索尼的PS4在智能电视上玩大型游戏。
因此，现有的音视频播放设备无法符合一机多用的使用需求，并且需要添加额外设备，徒增成本，从而导致用户体验不佳，而降低其对于使用音视频播放设备的意愿。

本发明提供的音视频播放设备，例如智能电视，通过处理器为性能指标上明显高于一般处理器的高性能处理器的配置；视频格式转换桥片作为外部视频信号与屏幕显示选单数据的传送媒介，并且可以对外部视频信号与屏幕显示选单数据的数据格式进行转换；以及运动补偿帧率转换器将外部视频信号处理为叠加有屏幕显示选单数据的高分辨率和高帧率视频信号，让音视频播放设备所接收到的视频信号适于在显示屏上播放，并且可以同步呈现屏幕显示选单，从而让音视频播放设备不仅具有执行高功耗软件的效能，同时还能提供高质量视频的观赏功能。因此在使用上，让用户能观赏高品质的视频，同时也能符合执行大型游戏的使用需求，从而提升了音视频播放设备整体的视听娱乐效能，大幅增进了用户体验，并且节省额外购买游戏机的成本。
附图概述
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明音视频播放设备的第一实施例的方块图；
图2为本发明音视频播放设备的第二实施例的方块图。
本申请的较佳实施方式
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。
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。
如图1所示，本发明第一实施例所揭露的音视频播放设备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。并且，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。视频格式转换桥片120分别耦接于处理器110与运动补偿帧率转换器130，并且可选择性地耦接于外部信号源，用以接收屏幕显示选单数据以及接收并转换来自外部信号源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与屏幕显示选单数据分别传送至运动补偿帧率转换器130。其中，外部信号源为外接于音视频播放设备10的DVD播放器或机顶盒等音视频输出设备，视频格式转换桥片120耦接于这些外接的影音装置，并且从中接收音视频信号。运动补偿帧率转换器130耦接于视频格式转换桥片120与显示屏20之间，用以接收并叠加转换后的外部视频信号与屏幕显示选单数据，并且传送至显示屏20。
在应用上，当输入音视频播放设备10通过视频格式转换桥片120从DVD播放器或机顶盒等外部信号源接收外部音视频信号时，来自外部信号源的外部视频信号(也就是外部信号源的音视频信号中的视频信号)通过视频格式转换桥片120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，使其符合运动补偿帧率转换器130的接收格式，然后将转换后的 外部视频信号传送至运动补偿帧率转换器130。其中，在转换后的外部视频信号从视频格式转换桥片120传送至运动补偿帧率转换器130的过程中，若处理器110接收到来自外部的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时，视频格式转换桥片120接收此屏幕显示选单数据并且进行数据格式的转换，使其数据格式被转换为符合运动补偿帧率转换器130可以接收的数据格式，然后再传送至运动补偿帧率转换器130。可以理解的是，若屏幕显示选单数据的初始数据格式即与动补偿帧率转换器130可以接收的数据格式相符时，可以省略数据格式转换的操作。
之后，运动补偿帧率转换器130即可以将所接收到的屏幕显示选单数据与外部视频信号进行叠加，然后再传送至显示屏20。
因此，在本发明实施例提供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作为外部视频信号与屏幕显示选单数据的传送媒介，并且可以对外部视频信号与屏幕显示选单数据的数据格式进行转换，让视频格式转换桥片所接收的外部视频信号可以在显示屏上进行播放，并同时呈现屏幕显示选单数据。此外，通过运动补偿帧率转换器对转换后的视频信号进行优化，可以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。
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。此外，本发明实施例所揭露的音视频播放设备10还可以外接DVD播放器或机顶盒等音视频输出设备，并以其作为外部信号源，从这些外接的影音装置中接收音视频信号。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，而外部信号源为上述外接于音视频播放设备的影音装置的音视频信号源。并且，在本发明实施例中，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。
本发明实施例所揭露的音视频播放设备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，分别耦接于处理器110。
值得说明的是，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。处理器110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处理器110从存储器模块180内读取的音视频数据。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(也就是来自主信号源30的主音频信号)传送至音频系统40以及将所接收的音视频信号中的视频信号(也就是来自主信号源30的主视频信号)传送至视频格式转换桥片120。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，例如，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，处理器110上电性设置有第一视频格式输出接口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)。而第一视频格式输出接口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，处理器110即通过第一视频格式输出接口112耦接于视频格式转换桥片120上相应的接口。
屏幕显示选单功能模块111用以根据处理器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，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处理器110，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，并且通过第一视频格式输出接口112传送至视频格式转换桥片120；或者通过处理器110将屏幕显示选单数据与主视频信号进行叠加，然后再通过第一视频格式输出接口112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(micro control unit,MCU)122、第二视频格式输出接口123、外部音视频输入接口124、音频输出接口125以及屏幕选单输出接口126。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112，用以从处理器110接收来自主信号源30的主视频信号、叠加后的主视频信号(也就是叠加有屏幕显示选单数据的主视频信号)或屏幕显示选单功能模块111所产生的屏幕显示选单数据。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对来自主信号源30的主视频信号、叠加后的主视频信号或来自外部信号源的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转换后的外部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112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112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。
视频格式转换桥片120的外部音视频输入接口124用以耦接于外部信号源，例如DVD播放器或机顶盒等音视频输出设备，以便于从音视频输出设备接收外部音视频信号。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。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，接着再传送至处理器110。
而视频格式转换桥片120的屏幕选单输出接口126耦接于运动补偿帧率转换器130上数据格式相应的接口，例如电性设置在运动补偿帧率转换器130上的屏幕选单输入接口132。其中，视频格式转换桥片120的屏幕选单输出接口126与第一视频格式输入接口121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，若屏幕选单输出接口126与第一视频格式输入接口121的数据格式相异，那么当视频格式转换桥片120在接收屏幕显示选单数据后，进一步地将屏幕显示选单数据进行数据格式的转换，使其符合屏幕选单输出接口126的传输格式，以便于传送至运动补偿帧率转换器130。
运动补偿帧率转换器130分别耦接于视频格式转换桥片120以及显示屏20，用以从视频格式转换桥片120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。
值得说明的是，在运动补偿帧率转换器130还用以从视频格式转换桥片120接收屏幕显示选单数据，并将其与转换后的外部视频信号进行叠加。并且在叠加操作上，可以是先进行屏幕显示选单数据与转换后的外部视频信号的叠加，然后再将叠加有屏幕显示选单数据的外部视频信号处理为高分辨率和高帧率视频信号；或者是在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后，再进行屏幕显示选单数据的叠加。以上仅是叠加操作的顺序不同，并且都能产生在显示屏20上呈现带有屏幕显示选单数据的高清晰度画面，因此上述的叠加顺序并非用以限制本发明。
以下通过一具体实施方式对本发明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；以及通过第一视频格式输出接口112将来自主信号源30的主视频信号传送至视频格式转换桥片120。在此过程中，处理器110还可以根据所接收到的外部操作指令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与主视频信号进行叠加，然后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120。因此，处理器110传送至视频格式转换桥片120的主视频信号可以是叠加有屏幕显示选单数据的主视频信号，或者是尚未叠加屏幕显示选单数据的主视频信号。在本实施例中，是以传送至视频格式转换桥片120的主视频信号为叠加有屏幕显示选单数据的主视频信号作为举例，但并不以此为限。并且，在叠加后的主视频信号的传送过程中，处理器110根据实际需求选择性地将叠加后的主视频信号 的数据格式转换为适用于第一视频格式输出接口112的数据格式，例如HDMI，然后再通过第一视频格式输出接口112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接收上述叠加后的主视频信号，并且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123将转换后的主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接收转换后的主视频信号后，运动补偿帧率转换器130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。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，从而在显示屏20上呈现出具有屏幕显示选单数据的高清晰度画面。
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，音视频播放设备10通过视频格式转换桥片120的外部音视频输入接口124接收外部音视频信号。其中，来自外部信号源的外部音频信号通过视频格式转换桥片120的音频输出接口125传送至处理器110，然后再通过处理器110提供至音频系统40进行播放。而来自外部信号源的外部视频信号(也就是外部信号源的音视频信号中的视频信号)通过视频格式转换桥片120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，然后再通过第二视频格式输出接口123将转换后的外部视频信号传送至运动补偿帧率转换器130，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。
其中，在外部视频信号从视频格式转换桥片120传送至运动补偿帧率转换器130的过程中，若处理器接收到来自外部的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时，视频格式转换桥片120通 过第一视频格式输入接口121接收此屏幕显示选单数据并且进行数据格式的转换，使其数据格式被转换为符合运动补偿帧率转换器130的屏幕选单输入接口132可以接收的数据格式，然后再通过屏幕选单输出接口126传送至运动补偿帧率转换器130。可以理解的是，若屏幕显示选单数据的初始数据格式即与动补偿帧率转换器130的屏幕选单输入接口132可以接收的数据格式相符时，可以省略数据格式转换的操作。
之后，运动补偿帧率转换器130即可以将所接收到的屏幕显示选单数据与外部视频信号进行叠加；或者是将所接收到的屏幕显示选单数据与已经处理为高分辨率和高帧率视频信号的外部视频信号进行叠加，然后再传送至显示屏20。
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处理器接收来自主信号源的音视频信号；或者是通过视频格式转换桥片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作为主视频信号、外部视频信号与屏幕显示选单数据的传送媒介，并且可以对主视频信号、外部视频信号与屏幕显示选单数据的数据格式进行转换，让处理器所接收的主视频信号或视频格式转换桥片所接收的外部视频信号可以在显示屏上进行播放，并同时呈现屏幕显示选单数据。此外，通过运动补偿帧率转换器对转换后的视频信号进行优化，可以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。
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。
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。
