Description

一种扩展显示标识数据EDID的处理方法和装置
本申请要求于2015年06月29日提交中国专利局、申请号为201510372281.8,发明名称为“一种扩展显示标识数据EDID的处理方法和装置”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
本发明涉及通信技术领域,尤其涉及一种扩展显示标识数据(Extended Display Identification Data,EDID)的处理方法和装置。
背景技术
杜比全景声(Dolby Atmos,也可以简称为ATMOS)是由杜比实验室研发,于2012年4月24日发布的全新影院音频平台。它突破了传统意义上5.1、7.1声道的概念,能够结合影片内容,呈现出动态的声音效果。不同于以往一路音频信号控制影院中一侧音箱发出相同的声音,它可以使一侧的多个音箱逐个发出不同声响,更真实的营造出由远及近的音效;配合顶棚加设音箱,实现声场包围,展现更多声音细节,提升观众的观影感受。
目前,显示设备一般都会包含高清晰度多媒体接口(High Definition Multimedia Interface,HDMI)模块,而在HDMI模块中通常会存储该显示设备的EDID,其中,EDID是一种视频电子标准协会(Video Electronics Standards Association,VESA)标准数据格式,其中包含有关显示设备的显示器及其性能的参数,包括供应商信息、最大图像大小、颜色设置、厂商预设置、频率范围的限制以及显示器名和序列号的字符串等等。外接设备在HDMI热插拔的时候会从HDMI模块中读取该EDID,其目的是获知显示设备所支持的特性,然后按照显示设备所支持的特性来输出相关内容。
随着ATMOS功能的出现,为了使外接设备能够按照显示设备所支持的特性来输出相关内容,就要求显示设备和与支持ATMOS功能的外接设备连接时,能够及时动态修改自身的EDID。

具体实施方式
为了解决现有技术中存在的问题,申请人对现有技术中的HDMI模块进行了深入分析。
如图1所示,为HDMI模块的架构示意图。其中,HDMI发送端可以是任何支持HDMI模块输出的设备,而HDMI接收端可以是任何带有HDMI模块输入的 设备。无论它们是音频设备、视频设备还是控制设备,HDMI模块都可以应用其中。
在HDMI模块中,数据信号采用的是最小化传输差分信号(Transition Minimized Differential Signaling,TMDS)协议。这种数据传输协议曾经在数字视频接口(Digital Visual Interface,DVI)模块上得到广泛的应用。而HDMI模块上的数据信号也沿用了这种协议。这种协议会将标准8bit数据转换为10bit信号,并且在转换过程中使用微分传送。微分传送这种技术也曾经被广泛的应用于千兆以太网的数据传输中。其中,在HDMI发送器和HDMI接收器之间,存在三个不同的TMDS传输通道和一个时钟通道,这些通道支持视频、音频数据和附加信息,视频、音频数据和附加信息通过三个TMDS传输通道传送到HDMI接收器上,而视频的像素时钟则通过时钟通道传送,HDMI接收器接收这个频率参数之后,再还原另外三个TMDS传输通道传递过来的信息。
在HDMI模块传输数据之前,HDMI发送端与HDMI接收端可利用显示数据通道(Display Data Channel,DDC)得知彼此的传送与接收能力,但实际应用中,HDMI发送端仅需单向获知HDMI接收端的能力即可。
基于上述对HDMI模块的分析,本发明实施例提供了一种EDID的处理方案。该技术方案中,一方面,当显示设备连接的外接设备支持ATMOS能力时,控制显示设备的HDMI模块,使显示设备与外接设备断开连接,并对显示设备的EDID进行更新,得到更新后的EDID,将更新后的EDID加载到HDMI模块中,再控制HDMI模块,使显示设备与外接设备重新连接,从而实现动态刷新显示设备的EDID的效果;另一方面,当显示设备连接的外接设备支持ATMOS能力时,将显示设备的HDMI模块去初始化,使显示设备与外接设备断开连接,并对显示设备的EDID进行更新,得到更新后的EDID,再将HDMI模块重新初始化,将更新后的EDID加载到重新初始化后的HDMI模块中,从而实现动态刷新显示设备的EDID的效果。
以下结合说明书附图对本发明的实施例进行说明,应当理解,此处所描述的实施例仅用于说明和解释本发明,并不用于限制本发明。并且在不冲突的情况下,本发明中的实施例及实施例的特征可以互相结合。
本发明实施例提供了一种EDID的处理方法,如图2所示,为该方法的实现流程图,具体包括下述步骤:
步骤21,当显示设备连接的外接设备支持ATMOS能力时,控制显示设备的HDMI模块,使显示设备与外接设备断开连接。
其中,本发明实施例中的外接设备可以但不限于为音频设备,比如音响等。
本发明实施例中,当显示设备与外接设备连接后,首先需要判断该外接设备是否支持ATMOS能力,当判断出该外接设备支持ATMOS能力时,则显示设备需要刷新自身的EDID,使外接设备能够获知显示设备也支持ATMOS能力,进而根据ATMOS能力向显示设备输出相应内容。
因此,为了使显示设备能够刷新自身的EDID,本发明实施例中当判断出显示设备连接的外接设备支持ATMOS能力时,控制显示设备的HDMI模块,使显示设备与外接设备断开连接,使得外接设备无法获取显示设备未更新的EDID。
可选的,本发明实施例中可以首先获取外接设备的音频能力集,再根据外接设备的音频能力集,判断外接设备是否支持ATMOS能力。
步骤22,对显示设备的EDID进行更新,得到更新后的EDID。
具体的,可以通过解析显示设备的EDID,确定显示设备的EDID需要更新的目标位置和目标值,再将确定出的目标位置的当前值更新为目标值,进而得到更新后的EDID。
步骤23,将更新后的EDID加载到HDMI模块中。
步骤24,控制显示设备的HDMI模块,使显示设备与外接设备重新连接。
当显示设备与外接设备重新连接后,外接设备便可以从显示设备中读取其更新后的EDID。
本发明实施例还提供了一种EDID的处理方法,如图3所示,为该方法的实现流程图,具体包括下述步骤:
步骤31,当判断出显示设备连接的外接设备支持ATMOS能力时,将显示设备的HDMI模块去初始化。
其中,本发明实施例中的外接设备可以但不限于为音频设备,比如音响等。
本发明实施例中,当显示设备与外接设备连接后,首先需要判断该外接设备是否支持ATMOS能力,当判断出该外接设备支持ATMOS能力时,则显示设备需要刷新自身的EDID,使外接设备能够获知显示设备也支持ATMOS能力,进而根据ATMOS能力向显示设备输出相应内容。
因此,为了使显示设备能够刷新自身的EDID,本发明实施例中当判断出显示设备连接的外接设备支持ATMOS能力时,将显示设备的HDMI模块去初始化,即将显示设备的HDMI模块去电,使显示设备与外接设备断开连接,使得外接设备无法获取显示设备未更新的EDID。
可选的,本发明实施例中可以首先获取外接设备的音频能力集,再根据外接设备的音频能力集,判断外接设备是否支持ATMOS能力。
步骤32,对显示设备的EDID进行更新,得到更新后的EDID。
具体的,可以通过解析显示设备的EDID,确定显示设备的EDID需要更新的目标位置和目标值,再将确定出的目标位置的当前值更新为目标值,进而得到更新后的EDID。
步骤33,将显示设备的HDMI模块重新初始化,将更新后的EDID加载到重新初始化后的HDMI模块中。
其中,重新初始化,即将HDMI模块重新上电,恢复正常工作状态。而在显示设备的HDMI模块重新初始化的过程中,会加载更新后的EDID,进而使得外接设备便可以从显示设备中读取其更新后的EDID。
具体的,本发明实施例中可以通过复位重启HDMI模块来实现。
