Description

烧录方法和烧录系统 技术领域
本发明涉及显示设备的制造领域，具体地，涉及一种向接收设备端上烧录密钥的烧录方法和一种执行该烧录方法的烧录系统。
背景技术
随着显示技术高速发展，功能要求越来越强，需要传输的数据越来越多。在现有技术中，需要使用高清晰度多媒体接口(High Definition Multimedia Interface，HDMI)传输数据。HDMI是一种高清数字接口标准，它可以提供很高的带宽，无损地传输数字视频和音频信号。在利用HDMI传输数据时需要用到高带宽数字内容保护(High-bandwidth Digital Content Protection，HDCP)，其中，HDCP技术是英特尔开发的为HDMI提供高带宽数字内容保护的解码技术。配备了HDCP技术的HDMI就不会受到信号加密的限制，可以接受全部格式的高清信号。HDCP是一个防止数字内容盗版的加密技术，如果软件和硬件其中之一不支持HDCP，我们就无法读取传输的数字内容。
所有支持HDCP的设备都有一组独特的密钥，通常，一个组密钥包括40把56bits长度的密钥。任何一个HDCP设备都必须有一组唯一的授权码(Device Key)，厂商在生产显示设备时需要向Digital-CP组织购买授权码，并且厂商在制造显示设备时必须确保每一台显示设备使用唯一的授权码，不得出现一个授权码被多台设备使用的情况。生产厂商需将购买后的授权码烧录到显示终端接口存储器中，以使得显示终端具有HDCP功能。
目前，烧写300字节左右的HDCP授权码采用的方法是用电脑配套的专用烧写工具来一次烧写到单个存储器中，由于每台机器要烧写300字节左右的HDCP授权码，烧写过程中容易出现数据丢失，不便于保证授权烧写的完整性。
在已往的技术中，在显示面板的包装车间生产线采用一个独立的工作站烧录进行HDCP设备授权码的烧录。这种烧录方法的烧录工作原理为通过若干信号线将计算机待烧录的显示设备相连接，通过计算机实现对HDCP设备授权码的管理，并且通过DDC/CI通信协议将 HDCP数据通过串口或者DDC通道传输给液晶显示终端处理芯片，由显示装置中的处理芯片完成HDCP设备授权码的写入。生产线作业员需要在显示设备接上信号线，等待信号稳定后再点击运行计算机内的烧录程序进行烧录，烧录完成后，再拔掉信号线，将烧录好的显示设备送到下一个工序。
由于生产车间环境较差，在线烧录受环境影响大，容易出现烧录不良；而且HDCP烧录站各自独立操作，不便于对HDCP设备授权码资料以及烧录程序是否准确进行管理，导致烧录失败也没有被发现。

比较模块，比较模块能够对第一验证码和第二验证码进行比较，并生成对比结果，当对比结果表明第一验证码和第二验证码不匹配时，比较模块向控制模块发出复位信号，控制模块根据复位信号生成复位指令，以控制第一通信模块再次向接收设备接收设备端发出设备密钥。
由此可知，利用本发明所提供的烧录方法可以确保将设备密钥成功地烧录在接收设备端，保证了接收设备的良率。

当所述第一验证码和所述第二验证码匹配时，所述烧录方法结束，烧录通过，可以以同样的方法进行下一个接收设备的烧录。当所述第一验证码和所述第二验证码不匹配时，回到步骤S103。
在本发明中，所述第一验证码和所述第二验证码匹配包括两种情况：
第一种，在所述操作设备端对待发送的设备密钥进行的运算与在所述接收设备端对所述接收到的设备密钥进行的运算相同时，所述第一验证码和所述第二验证码相匹配是指所述第一验证码和所述第二验证码相同；
第二种，在所述操作设备端对待发送的设备密钥进行的运算与在所述接收设备端对所述接收到的设备密钥进行的运算不同时，第一验证码和所述第二验证码相匹配是指，如果在所述操作设备端对待发送的设备密钥进行与“在所述接收设备端对所述接收到的设备密钥进行的运算”相同的运算后，可以获得与第二验证码相同的验证码。可以理解为，在所述操作设备端对待发送的设备密钥进行第一运算，获得第一验证码；在所述接收设备端对所述接收到的设备密钥进行第二运算，获得第二验证码，在这种采用不同的运算的情况下，如果在所述操作设备端对待发送的设备密钥进行第二运算得到的验证码和第二验证码相同，则可以说明第一验证码和第二验证码匹配。如此可以根据实际情况选取合适的匹配方法，从而简化计算量。
如果所述第一验证码与所述第二验证码匹配的话，则说明设备密钥在传输的过程中并没有出现数据丢失，从而表明所述设备密钥被正确地烧录在了接收设备端。如果所述第一验证码和所述第二验证码不匹配，则说明设备密钥在传输的过程中发生了数据丢失，需要重新向接收设备端发送设备密钥。
由此可知，利用本发明所提供的烧录方法可以确保将设备密钥成功地烧录在接收设备端，保证了接收设备端的良率。
需要指出的是，此处所述的“接收设备端”可以是已经完成的显 示设备，可以是显示设备的一部分。
此处所述的“烧录方法结束”是指向一台接收设备端烧录设备密钥的过程结束。可以继续利用所述烧录方法对其他的接收设备端进行设备密钥的烧录。此处所述的“设备密钥”可以是HDCP授权码，也可以是接收设备端接收数据所需要的其他密钥。
在图1中，获得第一验证码的步骤S101在将所述待发送的设备密钥发送至接收设备端的步骤S103之前进行，但是，本领域技术人员应当理解的是，获得第一验证码的步骤还可以和将所述待发送的设备密钥发送至接收设备端的步骤S103同步进行，或者，将所述待发送的设备密钥发送至接收设备端的步骤S103可以在获得第一验证码的步骤S101之前进行。
通常，操作设备端为电脑设备，具有运算、发送等功能，接收设备端可以为电视机、显示面板等，所述接收设备端可以包括芯片，该芯片也具有运算和发送的功能。在所述烧录方法中，对执行对所述第一验证码和所述第二验证码进行比较的步骤的设备不做具体的限定，也就是说，可以在接收设备端进行上述对所述第一验证码和所述第二验证码进行比较的步骤S107，也可以在操作设备端进行上述比较步骤。
例如，在本发明中，可以将所述设备密钥和所述第一验证码同时发送至接收设备端，在接收设备端完成所述第一验证码和所述第二验证码的对比，但这样需要在每一个接受设备端都设置处理芯片。
一般而言，电脑设备的运算能力要高于接收设备端的运算能力，所以，为了统一管理以及降低生产成本，优选地，可以在操作设备端进行上述对所述第一验证码和所述第二验证码进行比较的步骤。图2示出了在操作设备端进行上述对所述第一验证码和所述第二验证码进行比较的步骤。具体地，在操作设备端对所述第一验证码和所述第二验证码进行比较的步骤包括：
在步骤S201，将所述第二验证码发回所述操作设备端；
在步骤S203，在所述操作设备端对所述第一验证码和所述第二验证码进行对比，并生成对比结果。
为了便于操作人员判断烧录是否成功，优选地，烧录方法还包括在对第一验证码和第二验证码进行比较的步骤之后进行的：
在步骤S205，根据对比结果生成相应的提示信息。
而后在步骤S207，呈现提示信息。步骤S205和S207详述如下。
在本发明中，对提示信息的类型并不做限定。根据一个实施例，例如，可以在所述操作设备端设置报警装置，提示信息可以为两种不同的报警信号。例如，所述报警装置可以包括红灯和绿灯。判定烧录成功的提示信息可以为控制绿灯发光的控制信号，而判定烧录失败的提示信息可以为控制红灯发光的控制信号。当然，所述报警装置也可以为能够发出声音信号的装置，判定烧录成功的提示信息为两种不同的提示音。
为了便于生产接收设备端的产线上的操作人员及时了解到设备密钥是否烧录成功，优选地，可以在接收设备端呈现所述提示信息。相应地，在步骤S205之后，需要控制所述接收设备端显示所述提示信息。
在这种情况中，所述提示信息可以是显示信号，以控制所述接收设备端进行显示。当接收设备端上显示表征烧录成功的提示信息时，可以将所述接收设备端移动至下一个工位，进行下一道工序；当接收设备端上显示表征烧录失败的提示信息时，可以停止将接收设备端传送至下一道工序，并将接收设备端保持在当前工位，继续进行烧录。
为了便于观察，优选地，当所述第一验证码和所述第二验证码匹配时，所述提示信息的内容为第一信息(例如，“PASS”)；当所述第一验证码和所述第二验证码不匹配时，所述提示信息的内容为不同于所述第一信息的第二信息(例如，“ERR”)。
在本发明中，对在所述操作设备端对所述待发送的设备密钥进行的运算中的运算类型并不做限定。例如，优选地，在所述操作设备端对所述待发送的设备密钥进行的运算为：对所述待发送的设备密钥的所有数据进行求和运算，所述第一验证码为总和检验码。如上文中所述，在所述操作设备端对待发送的设备密钥进行的运算和在所述接收设备端中对接收到的设备密钥进行的运算可以是相同的，因此，当在所述操作设备端对待发送的设备密钥进行的运算为求和运算时，在所述接收设备端中对接收到的设备密钥进行的运算也为求和运算，所述第二验证码也为总和检验码。如此可以简化计算量，优化效率。
优选地，在所述步骤S103中，所述接收到的设备密钥存储在所述接收设备端的存储器中。在本发明中，所述存储器可以为电可擦可编程只读存储器(EEPROM，Electically Erasable Programmable Read-Only  Memory)中或闪存。
同样地，可以将所述第二验证码存储在所述存储器中，且所述第二验证码的放置地址紧连所述接收到的设备密钥的放置地址。如此可以方便信息的提取与调用。
作为本发明的另一个方面，如图3所示，提供一种烧录系统，包括操作设备端和接收设备端，所述烧录系统用于执行本发明所提供的上述烧录方法，其中，所述烧录系统包括；
第一运算模块110，设置在所述操作设备端，用于在操作设备端对待发送的设备密钥进行运算，以获得第一验证码；
控制模块120，设置在所述操作设备端，用于控制在所述接收设备端对接收到的设备密钥进行运算以获得第二验证码；
第一通信模块130，设置在所述操作设备端，用于将所述待发送的设备密钥和所述第一控制指令发送至待烧录的接收设备端；和
比较模块140，比较模块140能够对所述第一验证码和所述第二验证码进行比较，并生成对比结果，当所述对比结果表明所述第一验证码和所述第二验证码不匹配时，比较模块140向控制模块120发出复位信号，控制模块120根据所述复位信号生成复位指令，以控制第一通信模块130再次向接收设备端200发出所述设备密钥。
如上文中所述，当所述第一验证码和所述第二验证码匹配时，表明所述设备密钥正确地烧录在接收设备端200中，当所述第一验证码和所述第二验证码不匹配时，说明设备密钥在传输的过程中发生了数据丢失，需要进行重新传输。
由此可知，利用本发明所提供烧录系统进行所述烧录方法可以确保将设备密钥成功地烧录在接收设备端，保证了接收设备端的良率。
在本发明中，控制模块120、第一运算模块110和第一通信模块130都设置在操作设备端，形成为操作设备端100的一部分。
比较模块140可以设置在操作设备端也可以设置在接收设备端，在图3中所示的具体实施方式中，比较模块140设置在操作设备端，此时接收设备端200将所述第二验证码发回所述操作设备端100以用于比较。而当比较模块140设置在接收设备端200时，操作设备端100将第一验证码发送到操作设备端100以用于比较。
下面详细解释控制模块120如何控制在接收设备端对接收到的设 备密钥进行运算：第一种实施方式，控制模块120可以生成第一控制指令，第一通信模块130可以将所述第一控制指令发送至接收设备端200，且第一控制指令可以控制芯片210对接收到的设备密钥进行运算，以获得所述第二验证码；第二种实施方式，控制模块可以生成一种操作指令，通过第一通信模块130将该操作指令发送至接收设备端200之后，接收设备端200的芯片210可以在该操作指令的控制下产生所述第一控制指令。
为了便于操作者判定烧录是否成功，优选地，所述烧录系统还包括可以提示信息生成模块150，控制模块120能够根据所述对比结果控制提示信息生成模块150生成提示信息。
如上文中所述，在本发明中，对提示信息的类型并不做限定。例如，可以在所示操作设备端设置报警装置，提示信息可以为两种不同的报警信号。例如，所述报警装置可以包括红灯和绿灯。判定烧录成功的提示信息可以为控制绿灯发光的控制信号，而判定烧录失败的提示信息可以为控制红灯发光的控制信号。当然，所述报警装置也可以为能够发出声音信号的装置，判定烧录成功的提示信息为两种不同的提示音。
为了便于生产接收设备端的产线上的操作人员及时了解到设备密钥是否烧录成功，优选地，可以在接收设备端显示所述提示信息。相应地，提示信息生成模块150设置在所述操作设备端，当提示信息生成模块150生成所述提示信息时，控制模块120能够生成第二控制指令，所述第二控制指令能够控制所述接收设备端显示相应的提示信息，第一通信模块130能够向接收设备端200的芯片210发出所述提示信息和所述第二控制指令。
如图3中所示，接收设备端200包括显示面板220，当芯片210接收到所述提示信息和所述第二控制指令之后，可以控制显示面板220进行显示。在本发明中，对显示面板220的具体类型并不做限定，例如，所述显示面板220可以为液晶显示面板，也可以为有机发光二极管显示面板。除了芯片210和显示面板220之外，接收设备端200还包括用于与操作设备端100通信的第二通信模块260，第二通信模块260与第一通信模块130进行通信。
如上文中所述，当所述第一验证码和所述第二验证码匹配时，提 示信息的内容为第一信息(例如，“PASS”)；当所述第一验证码和所述第二验证码不匹配时，提示信息的内容为不同于所述第一信息的第二信息(例如，“ERR”)。
如上文中所述，所述第一运算模块对所述设备密钥进行的运算为：将所述设备密钥的所有数据求和，所述第一验证码为总和检验码。
容易理解的是，芯片210包括对接收到的设备密钥进行运算的第二运算模块。优选的是，所述第二运算模块可以执行与第一运算模块110相同的运算(例如，求和运算)。
接收设备端200还包括存储器230，当接收设备端200的芯片接收到来自操作设备端100的数据(包括设备密钥、第一控制指令、第二控制指令、显示信息、第二验证码等)时，存储在存储器230中。其中第二验证码的存储地址紧连所述接收到的设备密钥的存储地址。如上文中所述，存储器230可以为电可擦可编程只读存储器(EEPROM，Electically Erasable Programmable Read-Only Memory)中或闪存。接收设备端还可以包括启动开关240和复位电路250，启动开关240可以向芯片发出开始指令，复位电路250用于在烧录失败后向芯片提供复位指令。
在本发明中，操作设备端100和接收设备端200之间通过第一通信模块130和第二通信模块260进行通信，第一通信模块130和第二通信模块260可以为串口。作为本发明的一种具体实施方式，所述串口可以为RS232串口。可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
