Description

一种设置屏幕菜单透明度的方法和装置
本申请要求在2015年08月21日提交中国专利局、申请号为201510520267.8、发明名称为“一种设置屏幕菜单透明度的方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及数据处理技术领域，特别涉及一种设置屏幕菜单透明度的方法和装置。
背景技术
OSD(On Screen Display，屏幕菜单式调节方式)应用于显示器上，可以在显示屏幕上产生一些特殊的字形或图形，常用于电视机或者个人电脑的显示屏幕上，当用户操作电视机切换频道或调整音量、画质等，电视屏幕显示目前状态，用户通过显示在屏幕上的功能菜单调整各项参数，不但调整简单而且可调整的内容也更多。
如图1所示，为现有的智能电视系统处理器的结构示意图，处理器分别与以太网模块、Wi-Fi(Wireless Fidelity，无线保真)模块/蓝牙模块、电源管理模块和存储器模块以及音频系统和显示面板连接，其中，处理器通过I2S(Inter-IC Sound Bus，集成电路内置音频总线)接口与音频系统连接。经过处理器处理的视频数据输出至面板(Panel)显示，音频数据通过音频系统输出。处理器上还分别设置有HDMI(High Definition Multimedia Interface，高清晰度多媒体接口)1接口、HDMI2接口、高频头接口、分量接口和CVBS(Composite Video Broadcast Signal，复合视频广播信息)接口，各个接口用于传输遵循不同通讯标准的视频数据，不同通讯标准传输的视频数据格式不同。
目前，智能电视系统中对于OSD数据的处理流程如下：由智能视频处理器将接收到视频数据和处理器生成的OSD数据叠加后传输到显示屏幕进行显示。其中，显示屏幕显示OSD数据的透明度可以通过V-by-one(一种新兴的高速串口数据通讯标准)格式中的Alpha(透明度)数据进行设定，如视频数据中的ARGB(Alpha Red Green Blue)中的“A”即Alpha数据。以智能视 频数据处理器接收到的视频数据为HDMI格式视频数据为例，智能视频数据处理器可以将HDMI格式视频数据和将处理器生成的OSD数据转换为V-by-one格式数据并叠加后输出至显示屏幕进行显示。
对于经过智能电视系统内部处理的视频数据可以通过上述方式显示OSD数据，但是对于利用智能电视显示屏幕播放外部输入的视频数据过程中，如果用户需要调整智能电视显示参数时，则由智能电视处理器将生成的OSD数据输出后，在处理器外部进行视频数据和OSD数据的叠加，由于传送OSD数据时采用的HDMI接口标准格式中没有Alpha数据的设置，因此，在显示叠加后的外部视频信号与屏幕菜单数据时无法设置OSD数据的透明度，如果不设置OSD数据的透明度，OSD数据将遮挡显示屏幕当前正在显示的视频画面，降低了用户体验。
由此可见，如何在不支持传输Alpha数据的数据传输格式中传输Alpha数据成为现有技术中亟待解决的技术问题之一。

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。
如图2a所示，为本发明实施例提供的设置屏幕菜单透明度的方法实施例流程图，可以包括以下步骤：
S21、预先设定传输透明度Alpha数据的数据位。
具体实施时，数据发送方和数据接收方预先设定相同的传输协议及用于传输Alpha数据的数据位。设定了传输Alpha数据的数据位后，数据发送方在发送OSD数据时，可以在预先设定的数据位上传输Alpha数据，数据接收方在预先设定的数据位上识别OSD数据即可。
S22、传输OSD数据。
其中，传输的OSD数据中包含在预先设定的数据位上传输的Alpha数据。
S23、接收OSD数据。
S24、识别OSD数据中在预先设定的数据位上传输的Alpha数据。
S25、根据识别出的Alpha数据设置屏幕菜单透明度。
为了更好的理解本发明实施例，以下分别针对数据发送方发送OSD数据和接收方接收OSD数据的具体实施流程进行说明。基于数据发送方和数据接收方预先设定的、用于传输Alpha数据的数据位，如图2b所示，发送方向接收方发送OSD数据的流程可以包括以下步骤：
S211、发送方生成OSD数据。
具体实施时，发送方在接收到用户发送的参数调整指令时生成OSD数据。例如，发送方为智能电视处理器时，用户可以通过遥控器向智能电视处理器发送参数调整指令。
S212、发送方向接收方传输生成的OSD数据，OSD数据中包含在预先设 定的数据位上传输的Alpha数据。
较佳的，发送方可以利用RGB数据位向接收方传输OSD数据。例如，如果发送方生成的OSD数据为遵循HDMI格式的OSD数据时，发送方可以通过HMDI接口利用RGB数据位向接收方传输OSD数据。OSD数据由视频数据和Alpha数据组成，其中，视频数据的传输可以利用RGB数据位向接收方传输。基于此，本发明实施例提供的OSD发送方法中，可以利用部分RGB数据位来传输Alpha数据。
具体实施时，只要是不支持传输Alpha数据的数据传输格式均可利用上述的OSD数据发送方法向接收方传输OSD数据中的Alpha数据，本发明实施例中仅以HDMI格式数据为例对本发明实施例进行说明，其不构成对本发明实施例的限定。
根据目前的显示技术，通常采用24bit RGB数据位、30bit RGB数据位和36bit RGB数据位传输视频数据，bit位越多，显示屏幕显示的图像色彩越饱满，其中，24bit位传输方式中，R、G、B每一分量分别占用8bit数据位，30bit位传输方式中，R、G、B每一分量分别占用10bit数据位，36bit RGB数据位传输方式中，R、G、B每一分量分别占用12bit数据位。
为了尽量减少对显示屏幕显示的图像色彩的影响，本发明实施例中，可以利用6bitRGB数据位传输Alpha数据。
例如，对于利用30bitRGB数据位传输OSD数据中的视频数据和Alpha数据的传输方式中，可以利用其中的24bit传输视频数据，另外的6bit传输Alpha数据。
较佳的，可以分别使用R、G、B每一分量占用的数据位中的两位传输Alpha数据，具体使用R、G、B每一分量的哪两位数据位可以由发送方和接收方协商决定。例如，发送方和接收方可以协商在R[8]-R[9]、G[8]-G[9]、B[8]-B[9]共6bit数据位上传输OSD数据中的Alpha数据，则发送方在R[0]-R[7]、G[0]-G[7]、B[0]-B[7]共24bit数据位上传输OSD数据中的视频数据。
对于利用36bitRGB数据位传输OSD数据中的视频数据和Alpha数据的传输方式中，可以利用其中的30bit传输视频数据，另外的6bit传输Alpha数据。同样，具体使用R、G、B每一分量的哪两位数据位可以由发送方和接收方协商决定。例如，发送方和接收方可以协商在R[10]-R[11]、G[10]-G[11]、 B[10]-B[11]共6bit数据位上传输OSD数据中的Alpha数据，则发送方在R[0]-R[9]、G[0]-G[9]、B[0]-B[9]共30bit数据位上传输OSD数据中的视频数据。
当然，具体实施时，对于利用36bitRGB数据位传输OSD数据中的视频数据和Alpha数据的传输方式中，在对显示屏幕显示的图像色彩要求不高的应用场景下，也可以使用24bitRGB数据位传输OSD数据中的视频数据，其余的12bitRGB数据位用于传输Alpha数据。具体的，可以分别使用R、G、B每一分量占用的数据位中的4bit数据位传输Alpha数据。具体使用R、G、B每一分量的哪四位数据位同样可以由发送方和接收方协商决定。例如，发送方和接收方可以协商在R[8]-R[11]、G[8]-G[11]、B[8]-B[11]共12bit RGB数据位上传输OSD数据中的Alpha数据，则发送方在R[0]-R[7]、G[0]-G[7]、B[0]-B[7]共24bit数据位上传输OSD数据中的视频数据。
相应的，在接收方，可以根据与发送方预先设定的传输Alpha数据的数据位上接收并识别Alpha数据，具体的，如图2c所示，在接收方可以按照以下流程接收发送方发送的OSD数据：
S221、接收OSD数据。
在接收方接收到的OSD数据中包含发送方在预先设置的数据位上传输的Alpha数据。
其中，接收方可以通过HDMI接口接收OSD数据，具体的，OSD数据中包含发送方在预先协商的RGB数据位上传输的Alpha数据。较佳的，发送方分别使用RGB数据每一分量所占用数据位中的任两位传输Alpha数据。
S222、接收方识别接收到的OSD数据中在预先设定的数据位上传输的Alpha数据。
S223、根据识别出的Alpha数据设置屏幕菜单透明度。
进一步的，接收方将设置了屏幕菜单透明度的OSD数据与接收到的外部视频信号叠加后输出至显示屏显示。
为了更好的理解本发明实施例，以下以智能电视处理器生成并传输包含Alpha数据的OSD数据为例对本发明实施例的具体实施过程进行说明。
如图3所示，为用户利用智能电视显示屏幕播放外部视频数据时的应用场景示意图，包括智能电视处理器(其结构与图1相同，这里不再赘述)、HDMI输入桥片、HDMI转V-by-one桥片，其中，HDMI输入桥片、HDMI 转V-by-one桥片用于对智能电视处理器输出的数据进行格式转换，HDMI转V-by-one桥片设置有2个HDMI接口，HDMI1接口用于接收智能电视处理器输出的HDMI视频数据，HDMI2用于接收外部视频数据。当用户在利用智能电视观看外部视频的过程中，如果需要调整智能电视相关参数(例如，调节音量、调节显示对比度等)，则通过智能电视遥控器向智能电视处理器发送参数调整指令，智能电视处理器在接收到参数调整指令后，生成OSD数据并通过图3中的HDMI桥片将其传输给HDMI转V-by-one桥片，对于智能电视处理器生成的OSD数据，由于HDMI数据传输格式不支持OSD数据中的Alpha数据传输，因此，传输给HDMI转V-by-one桥片的OSD数据为不包含Alpha数据的OSD数据。由于Alpha数据用于设置OSD数据透明度，如果没有Alpha数据，则OSD数据在显示屏幕显示时将遮挡显示屏幕显示的画面，降低了用户体验。
为此，本发明实施例中，为了将智能电视处理器生成的OSD数据中的Alpha数据传输给HDMI转V-by-one桥片，可以利用传输视频数据的RGB数据位传输Alpha数据，智能电视处理器与HDMI转V-by-one桥片预先协商传输Alpha数据的数据位，假设智能电视处理器与HDMI转V-by-one桥片之间采用30bitRGB数据位传输视频数据，如图4a所示，为智能电视处理器利用30bitRGB数据位传输视频数据的数据传输序列示意图。
以智能电视处理器与HDMI转V-by-one桥片协商的用于传输Alpha数据的数据位为：R[8]-R[9]、G[8]-G[9]、B[8]-B[9]共6bit数据位为例，在发送方，智能电视处理器利用30bit位中的R[0]-[7]、G[0]-[7]、B[0]-[7]传输OSD数据中的视频数据，利用30bit位中的R[8]-[9]、G[8]-[9]、B[8]-[9]传输OSD数据中的Alpha数据。如图4b所示，为本发明实施例中智能电视处理器利用30bitRGB数据位传输OSD数据中的视频数据和Alpha数据的数据传输序列示意图。
在接收方，HDMI转V-by-one桥片将识别出R[8]-R[9]、G[8]-G[9]、B[8]-B[9]传输的Alpha数据。如图4c所示，为HDMI转V-by-one桥片内识别出的OSD数据传输序列示意图，其中OSD数据包括视频数据和Alpha数据。HDMI转V-by-one桥片根据识别出的Alpha数据设置屏幕菜单透明度，并将设置了屏幕菜单透明度后的OSD数据与接收到的外部视频信号叠加并输出至显示屏显示。
由此，本发明实施例实现了Alpha数据在智能电视处理器和HDMI转V-by-one桥片之间的传输，使得在HDMI转V-by-one桥片内可以根据Alpha数据设置对应的透明度。
本发明实施例提供的设置屏幕菜单透明度的方法中，通过预先设定传输Alpha数据的数据位置，使得发送方可以在预先设定的数据位上向接收方发送包含Alpha数据的OSD数据，接收方在预先设定的数据位上接收并识别Alpha数据，从而实现了Alpha数据的传输，使得接收方可以根据接收到的Alpha数据设置对应的透明度，避免了由于无Alpha数据时OSD数据遮挡显示屏幕当前显示画面造成用户体验不佳的问题。
基于同一发明构思，本发明实施例中还分别提供了一种设置屏幕菜单透明度的装置，由于上述装置解决问题的原理分别与上述的设置屏幕菜单透明度的OSD数据发送及接收方法相似，因此上述装置的实施可以参见方法的实施，重复之处不再赘述。

具体实施时，本发明实施例提供的设置屏幕菜单透明度的装置还可以包括：
数据叠加模块，用于将设置了屏幕菜单透明度后的OSD数据与接收到的外部视频信号叠加后输出至显示屏显示。
