技术领域
本申请涉及视频技术领域，尤其涉及一种视频的无线传输设备、视频播放设备、方法及系统。
背景技术
采用无线传输技术传输视频已经得到较为广泛的应用，目前用于视频传输的无线技术如2.4G无线传输(蓝牙、无线高保真(WIFI)等)，5G无线传输(WIFI等)，60G无线传输(802.11ad，无线高清(WIHD，Wireless High Definition)等)。
现有的无线传输技术的带宽能力有限，以现有带宽能力最高的WIHD技术为例，其带宽能力为3Gbps，能够支持1080P@60p的视频传输。其中，1080P@60p是指每秒播放60帧、每帧的分辨率为1080P。
随着视频技术的发展，超高清(UHD，Ultra High Definition)视频得到迅速的发展和普及。超高清视频的带宽超出了现有无线传输技术的带宽能力，以4K2K@30p的超高清视频为例，其带宽约为9Gbps，而现有带宽能力最高的WIHD技术的带宽能力仅为3Gbps，因此，现有无线传输技术还无法支持超高清视频(例如4K2K视频)的传输。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
如图1所示，本申请实施例提供一种视频的无线传输设备，该设备至少 包括：
视频处理器101，配置为将超高清视频数据转换为数据压缩模块支持的数据格式，将处理后的超高清视频数据发送给数据压缩模块。
数据压缩模块102，配置为对转换后的超高清视频数据进行压缩，将压缩后的超高清视频数据发送给无线传输模块。
其中，发送压缩后的超高清视频数据的带宽不超过无线传输模块所使用的无线传输协议的带宽能力。
无线传输模块103，配置为按照无线传输协议发送压缩后的超高清视频数据。
本申请实施例提供的视频的无线传输设备，由于将超高清视频数据压缩后发送，且发送压缩后的超高清视频数据的带宽不超过无线传输协议的带宽能力，因此可以利用无线传输技术传输压缩后的超高清视频数据。
实施中，数据压缩模块102可以为显示流媒体压缩(DSC，Display Stream Compression)压缩单元。具体实施中，DSC压缩单元可以采用视频电子标准协会(VESA，Video Electronics Standards Association)提供的DSC压缩技术对超高清视频数据进行压缩，具体实践过程中，可以根据VESA协会网站等颁布的标准、协议作出因时而定的调整。其具体电路结构可以采用现有结构实现，本申请实施例中不再一一赘述。由于DSC压缩技术的实现成本低，且是一种视觉无损压缩技术，因此，在本申请实施例提供的技术方案中采用DSC压缩单元作为数据压缩模块，可以降低实现成本，提高系统性能。
应当指出的是，在实施中以DSC压缩技术为例是因为该技术实现成本低，所以这里数据压缩技术是以DSC压缩技术为例的；但是，数据压缩模块还可以采用其他压缩技术，只要数据压缩模块在将转换后的超高清视频数据进行压缩后，发送压缩后的超高清视频数据的带宽不超过无线传输模块所使用的无线传输协议的带宽能力即可，DSC压缩技术仅用于教导本领域技术人员具体如何实施本申请，但不意味仅能使用DSC压缩技术一种方式，实施过程中可以结合实践需要来确定相应的压缩技术，本申请实施例对此不作限定。
基于上述任一无线传输设备的实施例，其中，无线传输模块可以但不仅限于是以下任意一种：WIFI传输单元，WIHD传输单元，蓝牙传输单元，802.11ad传输单元。
基于上述任一无线传输设备的实施例，其中，无线传输设备可以是机顶 盒，也可以是智能移动终端(例如智能手机)。
如果本申请实施例提供的无线传输设备是机顶盒，那么，在机顶盒与视频播放设备(例如电视)建立无线传输连接后，就可以将超高清视频压缩后通过建立的无线传输连接发送给视频播放设备。其中，超高清视频数据可以是外部视频源实时发送给机顶盒的，例如是外部视频源通过光纤、以太网等有线传输方式实时发送给机顶盒的超高清视频数据。超高清视频数据也可以是预先保存在机顶盒本地的。
如果本申请实施例提供的无线传输设备是智能移动终端，那么，在智能移动终端与视频播放设备(例如电视)建立无线传输连接后，就可以将超高清视频压缩后通过二者之间建立的无线传输连接发送给视频播放设备。其中，超高清视频数据可以是预先保存在智能移动终端本地的。例如，当用户希望通过大屏幕收看智能移动终端本地保存的超高清视频时，就触发智能移动终端与大屏幕的视频播放设备建立无线传输连接，由智能移动终端将超高清视频数据压缩后传输给视频播放设备播放。当然，超高清视频数据也可以是外部视频源实时发送给智能移动终端的，例如是外部视频源通过光纤、以太网等有线传输方式实时发送给机顶盒的超高清视频数据。
基于上述任一无线传输设备的实施例，数据压缩模块可以按照预设的压缩比对转换后的超高清视频数据进行压缩，或，所述数据压缩模块可以根据无线传输模块所使用的无线传输协议的带宽对转换后的超高清视频数据进行压缩。
由于发送压缩后的超高清视频数据的带宽不超过无线传输模块所使用的无线传输协议的带宽能力。也就是说，上述压缩比是根据超高清视频数据的带宽和无线传输协议的带宽能力确定的。
如图2所示，本申请实施例还提供了一种视频播放设备，其至少包括：
无线传输模块201，配置为按照无线传输协议接收压缩后的超高清视频数据，并发送给数据解压模块。
其中，发送压缩后的超高清视频数据的带宽不超过无线传输模块所使用的无线传输协议的带宽能力。
实施中，视频播放设备的无线传输模块与视频传输设备的无线传输模块采用相同的无线传输协议。
数据解压模块202，配置为对压缩后的超高清视频数据进行解压，并将解 压后的超高清视频数据发送给视频处理器。
视频处理器203，配置为将解压后的超高清视频数据转换为显示屏支持的播放格式，将处理后的超高清视频数据发送给显示屏。
显示屏204，配置为根据转换后的超高清视频数据显示超高清视频。
本申请实施例提供的视频播放设备，由于接收的是压缩后的超高清视频数据，其接收时的带宽不超过无线传输协议的带宽能力，因此可以利用无线传输技术传输压缩后的超高清视频数据。进而在视频播放设备侧对压缩后的超高清视频数据进行解压处理，从而在视频播放设备正常播放还原后的超高清视频。因此，本申请实施例提供的技术方案实现了利用无线传输技术传输超高清视频并播放。
实施中，数据解压模块202可以为DSC解压单元。DSC解压单元可以采用VESA提供的DSC解压技术对超高清视频数据进行解压。其具体电路结构可以采用现有结构实现，本申请实施例中不再一一赘述。由于DSC解缩技术的实现成本低，且是一种视觉无损解压缩技术，因此，在本申请实施例提供的奇数方案中采用DSC解缩单元作为数据解缩单元，可以降低实现成本，提高系统性能。
基于上述任一视频播放设备的实施例，其中，无线传输模块201可以采用以下任意一种：WIFI传输单元，WIHD传输单元，蓝牙传输单元，802.11ad传输单元。
基于上述任一视频播放设备的实施例，其中，视频播放设备可以但不仅限于是电视。当然，也可以是其他具有显示屏的视频播放装置。
基于上述任一视频播放设备的实施例，数据解压模块可以按照预设的压缩比对压缩后的超高清视频数据进行解压，或，
数据解压模块可以根据无线传输模块所使用的无线传输协议的带宽对压缩后的超高清视频数据进行解压。
实施中，数据解压模块与无线传输设备的数据压缩模块可以采用相同的压缩比，该压缩比可以是预先约定的。
如图3所示，本申请实施例提供一种视频的无线传输及播放系统，包括上述任一实施例提供的无线传输设备，和上述任一实施例提供的视频播放设备。
