技术领域
本发明涉及多媒体技术领域，尤其涉及一种音视频播放设备。
背景技术
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。

本发明提供一种音视频播放设备，包括：第一视频格式转换桥片、处理器以及第二视频格式转换桥片。其中，第一视频格式转换桥片用以接收音视频信号，以及转换音视频信号中的视频信号的数据格式；处理器分别 耦接于第一视频格式转换桥片以及第二视频格式转换桥片，处理器用以接收第一视频格式转换桥片输出的转换后的视频信号，并且将转换后的视频信号转换为第一数据格式视频信号，并且传送至第二视频格式转换桥片；第二视频格式转换桥片耦接于处理器与显示屏，用以接收第一数据格式视频信号以及将第一数据格式视频信号转换为第二数据格式视频信号，并且将第二数据格式视频信号传送至显示屏。
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，以及第一视频格式转换桥片与第二视频格式转换桥片对视频信号的数据格式进行转换，让音视频播放设备可以接收不同数据格式的音视频信号，并且在显示屏上播放，从而让音视频播放设备不仅能提供高质量视频的观赏功能外，还能兼具有执行高功耗软件的效能。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；
图3为本发明音视频播放设备的第三实施例的方块图。
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提供的音视频播放设备10包括第一视频格式转换桥片110、处理器120以及第二视频格式转换桥片130。第一视频格式转换桥片110用以接收音视频信号，以及转换音视频信号中的视频信号的数据格式，其中音视频信号可以是来自于电视信号源、来自互联网的信号源或本地端下载的信号源的主音视频信号；或者是来自于DVD播放器或机顶盒等外部信号源的外部音视频信号。处理器120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120可以是64位、主频2～2.5GHz的处理器，但并不以此为限。处理器120分别耦接于第一视频格式转换桥片110以及第二视频格式转换桥片130，处理器120用以接收第一视频格式转换桥片110输出的转换后的视频信号，并且将转换后的视频信号转换为第一数据格式视频信号，并且传送至第二视频格式转换桥片130。第二视频格式转换桥片130耦接于处理器120与显示屏20，用以接收第一数据格式视频信号以及将第一数据格式视频信号转换为第二数据格式视频信号，并且将第二数据格式视频信号传送至显示屏20。
在操作上，音视频播放设备10通过第一视频格式转换桥片110从主信号源30或外部信号源50接收到音视频信号后，先针对此音视频信号进行数据格式的转换，例如当第一视频格式转换桥片110为HDMI转MIPI CSI桥片时，第一视频格式转换桥片110将音视频信号中的视频信号的数据格式从HDMI转换为MIPI CSI，然后再传送至处理器120。处理器120接收转换后 的音视频信号后，将此音视频信号中的视频信号再次进行数据格式的转换，以便于符合第二视频格式转换桥片130的接收格式。例如，当第二视频格式转换桥片130为HDMI转V-by-One桥片时，处理器120将视频信号转换为数据格式为HDMI的第一数据格式视频信号，然后传送至第二视频格式转换桥片130。
视频格式转换桥片130接收第一数据格式视频信号后，将第一数据格式视频信号的数据格式从HDMI数据格式转换为V-by-One数据格式的第二数据格式视频信号，然后通过数据格式同样为V-by-One的第二视频格式输出接口133将第二数据格式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。
因此，在本发明的音视频播放设备中，通过第一视频格式转换桥片110的配置扩大了处理器可以接收的音视频信号的来源与类型，同时，由于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，通过第二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，从而提升显示画面的流畅度与质量，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。此外，当DVD播放器或机顶盒等音视频输出设备插接于音视频播放设备10，使两者间相互耦接时，音视频播放设备10可以将音视频输出设备作为外部信号源50，而从音视频输出设备接收音视频信号来进行音频和/或视频播放。
音视频播放设备10包括第一视频格式转换桥片110、处理器120、第二视频格式转换桥片130以及运动补偿帧率转换器140，其中第一视频格式转换桥片110通过内部整合电路(Inter-Integrated Circuit，I2C)总线以及I2S (Inter-IC Sound)音频总线(又称集成电路内置音频总线)耦接于处理器120，并且在第一视频格式转换桥片110上电性设置有主音视频信号输入接口111与外部音视频信号输入接口112。主音视频信号输入接口111和外部音视频信号输入接口112可以是但并不局限于高清晰度多媒体接口(High Definition Multimedia Interface；以下简称HDMI)，且主视频信号输入接口111用以耦接于主信号源，而外部音视频输入接口112用以耦接于外部信号源，让第一视频格式转换桥片110可以通过主音视频信号输入接口111或外部音视频信号输入接口112接收音视频信号，然后将音视频信号中的音频信号和视频信号的数据格式转换为适于处理器120接收的数据格式，例如分别在第一视频格式转换桥片110和处理器120上设置有相对应的音视频信号输出接口与输入接口，优选的为MIPI CSI接口150。
处理器120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120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120。
处理器120上电性设置有第一视频格式输出接口121以及处理模块122，其中处理模块122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121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120即通过第一视频格式输出接口121耦接于第二视频格式转换桥片130上相应的接口。
此外，处理器120还通过I2C总线分别耦接于第二视频格式转换桥片130与运动补偿帧率转换器140；以及通过I2S音频总线耦接于音频系统40。因 此，处理器120可以从第一视频格式转换桥片110接收转换后的音频信号，并且将其传送至音频系统40；以及将转换后的视频信号的数据格式再转换为第一数据格式视频信号，例如HDMI数据格式的视频信号，以便于符合处理器120与第二视频格式转换桥片130之间的信号传输格式，然后再通过第一视频格式输出接口121将第一数据格式视频信号传送至第二视频格式转换桥片130。
其中，处理器120还分别耦接于配置在音视频播放设备10内的以太网模块160、无线通信模块170、电源管理模块180以及存储器模块190，并且可以从以太网模块160、无线通信模块170或存储器模块190获得音视频信号，这些音视频信号也可以当作是另一主信号源的音视频信号，例如：通过以太网模块160或无线通信模块170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190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。并且，将这些音视频信号中的音频信号传送至音频系统40以及将这些音视频信号中的视频信号传送至第二视频格式转换桥片130。
第二视频格式转换桥片130上电性设置有第一视频格式输入接口131、微控制单元(micro control unit,MCU)132以及第二视频格式输出接口133。第一视频格式输入接口131耦接于处理器120的第一视频格式输出接口121，用以从处理器120接收第一数据格式视频信号。而第二视频格式输出接口133耦接于运动补偿帧率转换器140上电性设置的第二视频格式输入接口141，用以在第二视频格式转换桥片130对第一数据格式视频信号进行数据格式的转换后，将转换后的视频信号(也就是第二数据格式视频信号)传送至运动补偿帧率转换器140。
其中，第二视频格式转换桥片130的第一视频格式输入接口131的数据格式与处理器120的第一视频格式输出接口121的数据格式相同，例如同样为HDMI数据格式；第二视频格式转换桥片130的第二视频格式输出接口133的数据格式与处理器120的第一视频格式输出接口121的数据格式相异，例如为V-by-One数据格式。可以理解的是，由于第二视频格式转换桥片130 的第二视频格式输出接口133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。
运动补偿帧率转换器140除了耦接于第二视频格式转换桥片130外，还耦接于显示屏20，用以从第二视频格式转换桥片130接收第二数据格式视频信号，并且基于运动检测与运动补偿(motion estimation and motion compensation,MEMC)原理对第二数据格式视频信号进行帧频转换(frame rate conversion,FRC)，从而将第二数据格式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的第一视频格式转换桥片110从主信号源30或外部信号源50接收到音视频信号后，先针对此音视频信号进行数据格式的转换，例如当第一视频格式转换桥片110为HDMI转MIPI CSI桥片时，第一视频格式转换桥片110可以通过HDMI数据格式的主音视频信号输入接口111或外部音视频信号输入接口112接收HDMI数据格式的音视频信号，然后将音视频信号中的音频信号的数据格式从HDMI转换为I2S以及将视频信号的数据格式从HDMI转换为MIPI CSI，然后再传送至处理器120。
处理器120接收转换后的音视频信号后，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40进行播放；以及将此音视频信号中的视频信号再次进行数据格式的转换，以便于符合第二视频格式转换桥片130的接收格式。例如，当第二视频格式转换桥片130为HDMI转V-by-One桥片时，处理器120将视频信号转换为数据格式为HDMI的第一数据格式视频信号，然后通过数据格式同样为HDMI的第一视频格式输入接口121的传送以及第一视频格式输出接口131的接收，让第一数据格式视频信号传送至第 二视频格式转换桥片130。
视频格式转换桥片130接收第一数据格式视频信号后，将第一数据格式视频信号的数据格式从HDMI数据格式转换为V-by-One数据格式的第二数据格式视频信号，然后通过数据格式同样为V-by-One的第二视频格式输出接口133将第二数据格式视频信号传送至运动补偿帧率转换器140。
接着，在通过第二视频格式输入接口141接收第二数据格式视频信号后，运动补偿帧率转换器140对第二数据格式视频信号进行运动检测、运动补偿以及帧频转换，使第二数据格式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上呈现出高清晰度画面。
因此，在本发明的音视频播放设备中，通过第一视频格式转换桥片110的配置扩大了处理器可以接收的音视频信号的来源与类型，同时，由于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，通过第二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。
值得说明的是，在本发明的音视频播放设备中，若处理器与第二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，为本发明音视频播放设备的第三实施例的方块图。本发明第三实施例与第二实施例在整体架构上大致相同，两者间的差异在于，本发明第三实施例所揭露的音视频播放设备10包括第一视频格式转换桥片110、处理器120以及第二视频格式转换桥片130，其中第一视频格式转换桥片110耦接于主信号源30和/或外部信号源50，处理器120耦接于第一视频格式转换桥片110与第二视频格式转换桥片130之间，而第二视频格式转换桥片130 通过第二视频格式输出接口133耦接于显示屏20。因此，当来自主信号源30和/或外部信号源50的音视频信号从第一视频格式转换桥片110输入，以及被处理器120将其中的视频信号转换为第一数据格式视频信号后，第一数据格式视频信号通过第二视频格式转换桥片130转换为第二数据格式视频信号，并且直接的传送至显示屏20上播放，而省略了高分辨率和高帧率的处理程序。
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。
