而一些高性能的音视频播放设备，例如：电脑、手机等，由于处理器的主频与寄存器的位数高于一般的处理器(例如，若一般处理器为32位、主频1.2千兆赫兹(GHz)，则高性能的音视频播放设备的处理器可以是64位、主频2～2.5GHz的处理器，这是相对值)，因此，播放高清晰度视频或者处理大型游戏的能力较强。但是，如果采用这些音视频播放设备播放外部视频信号，其中，外部视频信号来源于除音视频播放设备中的处理器以外的视频信号源，当需要对音视频播放效果进行调节，则无法同时显示外部视频信号和屏幕菜单。

附图说明
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为本发明实施例提供的音视频播放设备的结构示意图之一；
图2为本发明实施例提供的音视频播放设备的结构示意图之二；
图3为本发明实施例提供的音视频播放设备的结构示意图之三；
图4为本发明实施例提供的音视频播放设备的结构示意图之四。
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，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，以上仅用以举例说明，但并不以此为限。
本发明实施例提供的一种音视频播放设备，如图1所示，包括处理器11、视频格式转换桥片12和显示屏13；
处理器11，用于产生屏幕菜单数据并输出给视频格式转换桥片12；
视频格式转换桥片12，耦接于处理器11，用于将接收到的外部视频信号与处理器11输出的屏幕菜单数据叠加，并将叠加后的信号转换为显示屏13能够识别的格式的信号后传输至显示屏13；其中，外部视频信号来源于处理器11以外的视频信号源；
显示屏13，用于显示接收到的信号。
其中，显示屏13可以是但并不局限于音视频播放设备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的多媒体装置。
本发明实施例提供的音视频播放设备内还可配置以太网模块、有线和/或无线通信模块(例如蓝牙模块、无线保真度(Wireless Fidelity，Wi-Fi)模块、2.4G通信模块等)、电源管理模块、存储器模块及其组合其中之一，这些模块均与处理器11相连。
本发明实施例提供的音视频播放设备如图2所示，其中的处理器11电性设置有第一视频格式输入接口111及至少一个视频格式输出接口112，第一视频格式输入接口111耦接于主信号源21，用于将主信号源21的主视频信号与处理器11产生的屏幕菜单数据相叠加，并通过视频格式输出接口112输出给视频格式转换桥片12；
视频格式转换桥片12，还用于将从处理器11输出的叠加后的主视频信号 转换为显示屏13能够识别的格式的信号后传输至显示屏13。
其中，主信号源21可以是但并不局限于电视信号源；主视频信号可以是图2所示的音视频播放设备从配置于音视频播放设备内的以太网模块与有线和/或无线通信模块其中之一发送至处理器11的视频信号或者是处理器11从存储器模块内读取的视频数据等。并且，处理器11还用以将主视频信号与产生的屏幕菜单数据叠加后传送至视频格式转换桥片12。处理器11产生屏幕菜单数据，并通过自身的任一视频格式输出接口将屏幕菜单数据输出至视频格式转换桥片12。
其中，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)、高清晰度多媒体接口(High Definition Multimedia Interface，HDMI)、低压差分信号(Low Voltage Differential Signaling，LVDS)接口、显示接口(Display Port，DP)、嵌入式显示接口(Embedded Display Port，EDP)、移动行业处理器及显示器串行接口(Mobile Industry Processor Interface-Display Serial Interface，MIPI DSI)、逻辑门电路(Transistor-Transistor Logic，TTL)接口及其组合其中之一。
处理器11中包括处理模块以及屏幕显示选单功能模块。其中，处理模块包括中央处理单元(Central Processing Unit，CPU)和/或图形处理单元(Graphic Processing Unit，GPU)。处理模块可输出主视频信号，屏幕显示选单功能模块用于根据接收到的操作指令生成屏幕菜单数据。
处理器11中的屏幕显示选单功能模块根据所接收到的操作指令产生相应的屏幕菜单数据。例如，在需要使用菜单的场景下，处理器11中的屏幕显示选单功能模块根据外部的输入指令产生屏幕菜单选单数据，在本发明实施例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处理器11中的屏幕显示选单功能模块，处理器11中的屏幕显示选单功能模块即依据此功能指令产生相应的屏幕菜单数据，处理器11将屏幕菜单数据传送至视频格式转换桥片12，或者通过处理器11中的处理模块将其与主信号源21的主视频信号进行叠加，然后再将叠加有屏幕菜单数据的主视频信号传送至视频格式转换桥片12。
若视频格式转换桥片12中叠加后的视频信号的格式为第一视频格式，例如HDMI格式，其中，视频格式转换桥片12中叠加后的视频信号，可以是视频格式转换桥片12将外部视频信号与屏幕菜单数据相叠加形成的，也可以是 视频格式转换桥片12接收到的处理器11输出的叠加后的视频信号；而显示屏能够识别的视频信号的格式为第二视频格式，例如V-by-One格式，则视频格式转换桥片要将第一视频格式的数据转换为第二视频格式的数据后，才能传输给显示屏。可以理解的是，当第一视频格式与第二视频格式相同时，视频格式转换桥片无需再进行视频格式的转换。
本发明实施例提供的音视频播放设备，如图3所示，视频格式转换桥片12电性设置有外部音视频输入接口121，耦接于外部信号源31，用于接收来自外部信号源31的外部音频信号与外部视频信号。
视频格式转换桥片12将接收到的外部音频信号传输给处理器11，在图3中，处理器11还耦接有音频系统32，用于播放主信号源的主音频信号和/或外部音频信号。其中，音频系统32可以是但并不局限于音视频播放设备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的多媒体装置。
而对于来自于外部信号源31中的外部视频信号，由视频格式转换桥片12将外部视频信号与处理器11产生的屏幕菜单数据相叠加，并将叠加后的信号转换为显示屏13可以识别的格式，例如V-by-One，输出至显示屏13显示。
当然，如果从配置于音视频播放设备内的以太网模块与有线和/或无线通信模块其中之一发送至处理器11的音频数据或者是处理器11从存储器模块内读取的音频数据的话，处理器11和音视频播放设备中的音频系统32直接播放该音频数据。
也就是说，当视频格式转换桥片12接收到外部视频信号时，若处理器11产生屏幕菜单数据并输出给视频格式转换桥片12，那么，该视频格式转换桥片12将外部视频信号与接收到的屏幕菜单数据相叠加，并将叠加得到的信号转换为显示屏13能够识别的格式后，传输至显示屏13显示。当视频格式转换桥片12未接收到的外部视频信号，处理器11直接将主视频信号与产生的屏幕菜单数据相叠加，并将叠加得到的信号传输给视频格式转换桥片12，视频格式转换桥片12将接收到的叠加后的信号转换为显示屏13能够识别的格式后，传输至显示屏13显示。当视频格式转换桥片12接收到外部音频信号后，视频格式转换桥片12将接收到的外部音频信号传输至处理器11，由处理器11和音视频播放设备中的音频系统32播放。来自于主信号源的音频信号由与主信号源耦接的处理器11传输至音频系统32从而播放。
其中，处理器11向视频格式转换桥片12传输屏幕菜单数据可以通过通用串行总线(Universal Serial Bus，USB)接口，例如USB3.1传输，也可以通过HDMI传输，还可以通过其他接口传输，只要视频格式转换桥片12能够识别即可。
当处理器11通过USB接口向视频格式转换桥片12传输屏幕菜单数据时，视频格式转换桥片12上可以电性设置两个HDMI，其中，视频格式转换桥片12通过一个HDMI接收处理器11输出的主视频信号与屏幕菜单数据叠加后的信号，视频格式转换桥片12通过另一个HDMI接收外部信号源31输出的外部视频信号和外部音频信号。
当处理器11通过HDMI向视频格式转换桥片12传输屏幕菜单数据时，视频格式转换桥片12上可以电性设置三个HDMI，其中，视频格式转换桥片12通过一个HDMI与处理器11相连，用于接收处理器11输出的屏幕菜单数据，或者接收处理器11输出的主视频信号与屏幕菜单数据叠加后的信号，视频格式转换桥片12通过另外两个HDMI接收外部信号源31输出的外部视频信号和外部音频信号。
上述视频格式转换桥片12中的外部音视频输入接口121可以是但并不局限于MHL、HDMI、LVDS接口、DP、EDP、MIPI DSI、TTL接口及其组合其中之一。
显示屏13能够识别的格式可以为V-by-One。
当本发明实施例提供的音视频播放设备还包括帧率转换/运动估计和运动补偿(Frame Rate Conversion/Motion Estimation and Motion Compensation，FRC/MEMC)芯片时，本发明实施例提供的音视频播放设备如图4所示。
在图4所示的音视频播放设备中，FRC/MEMC芯片14连接在视频格式转换桥片12与显示屏13之间，用以从视频格式转换桥片12接收格式转换后视频信号，并且基于运动检测与运动补偿原理对转换后的视频信号进行帧频转换，从而将接收到的视频信号处理为高分辨率和高帧率的视频信号，例如从普通60赫兹(Hz)刷新率的视频内容提升到120Hz或者240Hz刷新率的视频内容；或者对接收到的视频信号进行分辨率的处理，若此接收到的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。然后将此高分辨率和高帧率的视频信号传送至显示屏13进行播放，从而提高运动画面的清晰程度。
在图4所示的音视频播放设备中，对视频格式转换桥片12接收到的外部音频信号的处理过程如虚线所示。对视频格式转换桥片12接收到的外部视频信号和屏幕菜单数据的处理过程如实线所示，视频格式转换桥片12将接收到的外部视频信号与处理器11输出的屏幕菜单数据叠加，并将叠加后的信号转换为显示屏13能够识别的格式的信号后通过FRC/MEMC芯片14传输至显示屏13。对处理器11输出给视频格式转换桥片12的主视频信号与屏幕菜单数据叠加后的视频信号的处理过程如点划线部分所示，其中，视频格式转换桥片12将叠加后的主视频信号与屏幕菜单数据转换为格式能够被显示屏13识别的信号，并通过FRC/MEMC芯片14处理后传输至显示屏13的过程与视频格式转换桥片12处理叠加后的外部视频信号和屏幕菜单数据的过程相同，因此在图4中未示出。

在一种可能的实施方式中，本发明实施例提供的音视频播放设备中，存储器中还存储用于执行以下步骤的程序：将叠加信号转换为高分辨率和高帧率的视频信号；显示高分辨率和高帧率的视频信号。
在一种可能的实施方式中，本发明实施例提供的音视频播放设备中，存 储器中还存储用于执行以下步骤的程序：将叠加信号转换为V-by-One格式。
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。
