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。
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包括智能电视***单芯片(TVSOC)110、处理器120以及视频格式转换桥片130。其中,智能电视***单芯片110用以接收音视频信号,并对音视频信号解码后传送至处理器,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分别耦接于智能电视***单芯片110以及视频格式转换桥片130,处理器120用以接收解码后的音视频信号,并转换解码后的音视频信号中的视频信号为第一数据格式视频信号,并且将第一数据格式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。
其中,当音视频播放设备10的智能电视***单芯片110从主信号源30或外部信号源50接收到音视频信号后,智能电视***单芯片110先针对音视频信号进行解码,然后传送至处理器120。处理器120接收并转换解码后的音视频信号的数据格式,例如根据实际需求选择性地将解码后视频信号的数据格式转换为数据格式为HDMI的第一数据格式视频信号,让解码后的音视频信号中的视频信号适于被视频格式转换桥片130接收。
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数据格式转换为第二数据格式视频信号,例如V-by-One数据格式的视频信号,然后再将第二数据格式视频信号传送至显示屏20进行播放。
基于上述,在本发明的音视频播放设备中,通过智能电视***单芯片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适于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***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***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包括智能电视***单芯片(TVSOC)110、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,其中智能电视***单芯片110上电性设置有音视频信号输入接口111,例如高清晰度多媒体接口(High Definition Multimedia Interface;以下简称HDMI)、模拟信号输入接口、数字信号输入接口、分量输入接口、AV输入接口、高频头输入接口、复合视频广播信号(Composite Video Baseband Signal,CVBS)输入接口等信号源输入接口;以及上述接口的组合其中之一。并且,智能电视***单芯片110通过音视频信号输入接口111耦接于主信号源30和/或外部信号源50,以便于从主信号源30和/或外部信号源50接收音视频信号,然后对音视频信号解码后传送至处理器120,其中智能电视***单芯片110可以是但并不局限于通过通用串行总线(Universal Serial Bus;以下简称USB)耦接于处理器120,例如,分别在智能电视***单芯片110和处理器120上设置有相对应的USB接口150,优选的为USB3.1接口,并通过USB连接线相互耦接,让智能电视***单芯片110可以将4K*2K的视频数据传送至处理器120。
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)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耦接于视频格式转换桥片130上相应的接口。
此外,处理器120还通过内部整合电路(Inter-Integrated Circuit,I2C)总线分别耦接于视频格式转换桥片130与运动补偿帧率转换器140;以及通过I2S(Inter-IC Sound)音频总线(又称集成电路内置音频总线)耦接于音频***40。因此,处理器120可以从智能电视***单芯片110接收解码后的音视频信号,并且将解码后的音视频信号中的音频信号传送至音频***40;以及对解码后的音视频信号中的视频信号进行数据格式的转换,使其被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***40以及将这些音视频信号中的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,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;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除了耦接于视频格式转换桥片130外,还耦接于显示屏20,用以从视频格式转换桥片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的智能电视***单芯片110从主信号源30或外部信号源50接收到音视频信号后,智能电视***单芯片110先针对音视频信号进行解码,然后通过USB接口150传送至处理器120。处理器120接收并转换解码后的音视频信号的数据格式,让解码后的音视频信号中的音频信号适于传送至音频***40,以及让解码后的音视频信号中的视频信号适于传送至视频格式转换桥片130,其中,处理器120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***40;以及将解码后的音视频信号中的视频信号转换为第一数据格式视频信号后,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视频格式转换桥片130,在此传送过程中,处理器120根据实际需求选择性地将解码后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121的数据格式,例如HDMI,然后再通过第一视频格
式输出接口121传送至视频格式转换桥片130。
值得说明的是,如果智能电视***单芯片110从外部信号源50接收的数据量较大,例如HDMI2.0全带宽18Gbps,而设置于智能电视***单芯片110与处理器120上的USB3.1接口的带宽仅有10Gbps,此时智能电视***单芯片110可以先针对所接收的外部音视频信号的数据进行压缩处理,使其满足USB接口传输带宽的数据,然后再送到处理器120,让处理器120对其解码后再将其中的音频信号传送至音频***播放以及将其中的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通过第一视频格式输入接口131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数据格式转换为第二数据格式视频信号,例如V-by-One数据格式的视频信号,然后通过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,通过智能电视***单芯片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包括智能电视***单芯片110、处理器120以及视频格式转换桥片130,其中智能电视***单芯片110耦接于主信号源30和/或外部信号源50,处理器120耦接于智能电视***单芯片110与视频格式转换桥片130之间,而视频格式转换桥片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的音视频信号被智能电视***单芯片110解码,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。

进而,将第一数据格式视频信号的数据格式从HDMI数据格式转换为第二数据格式视频信号,例如V-by-One数据格式的视频信号,然后再将第二数据格式视频信号传送至显示屏进行播放,以使得第二数据格式视频信号适于显示屏的播放。
基于上述,在本发明的音视频播放方法中,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,通过对视频信号进行数据格式转换,让接收的视频信号适于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。

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。
