Description

机顶盒的升级、换台方法及系统 技术领域
本公开涉及数字电视领域，例如涉及一种机顶盒的升级、换台方法及系统。
背景技术
数字电视机顶盒已经经历十几年的发展，在数字化大潮促进下，数字机顶盒市场需求量大。中国拥有庞大的机顶盒生产能力，2010年仅中国数字机顶盒生产规模就达到8236万台，2011年达到9810万台。2013-2015年3年间，数字电视机顶盒为机顶盒创造约2.5亿台的市场需求。2015年底我国有85％的有线电视用户转换为数字电视用户，伴随着我国城镇化率的提高，机顶盒市场还将延伸。
机顶盒融合了计算机、通信、多媒体、网络及智能卡等多种技术，其功能越来越强大和智能化，作为家庭信息处理中心，智能机顶盒具备与家庭信息相关的功能，且容易实现功能扩展。机顶盒的功能可以有：高速互联网(Internet)访问、接收数字电视节目、视频点播(Video-On-Demand，VOD)、音频点播(Audio-on-Demand，AOD)、电子游戏、互联网协议(Internet Protocol，lP)电话、可视电话和会议电视、远程教育、远程医疗、多屏互动等。
空中下载(Over-The-Air，OTA)指用户终端可以直接通过信号通道的接收下载方式，在用户终端上进行安装和更新软件，也叫作空中升级。数字机顶盒空中升级技术能够在不改变机顶盒硬件结构的情况下，升级软件系统，排除软件错误以及加入新的特性。为了维护运营商和用户的利益，可以在机顶盒中增加空中升级功能。一方面运营商可以不断通过空中升级推广增值业务，另一方面机顶盒开发者可以通过空中升级修复机顶盒软件中存在的问题，用户还可以通过升级体验更多的服务。
数字机顶盒软硬件技术在中国并没有完善的标准，OTA也没有统一的标准，造成了机顶盒升级过程可能会出现很多问题，比如升级慢就成为OTA升级瓶颈，当停电、或者无耐心/不知情的用户在“漫长的”升级过程中关机等原因导致终止机顶盒升级时，很可能导致机顶盒软件被破坏而无法再次开机，大面积出现这类状况时则会导致升级事故，而解决这类事故需要花费大量的人力、财力。

附图说明
为了更清楚地说明本实施例中的技术方案，下面将对本实施例描述中所需要使用的附图作简单的介绍。
图1是本实施例提供的一种机顶盒的升级方法的方法流程图；
图2是本实施例提供的另一种机顶盒的升级方法的方法流程图；
图3是本实施例提供的一种换台方法的方法流程图；
图4是本实施例提供的一种机顶盒的升级系统的结构方框图；
图5是本实施例提供的另一种机顶盒的升级系统的结构方框图；
图6是本实施例提供的一种换台系统的结构方框图；以及
图7是本实施例提供的一种机顶盒的硬件结构示意图。
具体实施方式
下面结合附图并通过实施方式来说明本实施例的技术方案。在不冲突的情况下，以下实施例和实施例中的特征可以相互组合。
本实施例中，“第一”，“第二”等词语(如果存在)用来表示名称，而并不表示任何特定的顺序。
参考图1，本实施例提供一种机顶盒的升级方法，可以包括如下操作。
在步骤110中，在后台接收机顶盒的第一升级数据，将所述第一升级数据整理后写入到闪存(flash)的至少一个分区的空闲地址，并记录所述第一升级数据的地址信息，写入升级标志。
在将第一升级数据整理后写入到flash时，可以从flash第一个分区开始遍历到最后一个分区，当发现当前分区的空闲空间大小等符合写入时，就写入到该分区中，停止遍历其他分区。当该分区空闲空间大小不够写入时，写入一部分第一升级数据，剩余未写入的第一升级数据再按此规则依次遍历后面的分区。
写入升级标志可理解为：机顶盒在后台检测到存在第一升级数据时将升级标志写到flash特定的分区中。升级标志可以有三个作用：1、标识已检测到第一升级数据；2、标识第一升级数据的升级类型，比如强制升级、手动升级等；3、标识当前升级数据的来源类型，比如来源于OTA、通用串行总线(Universal Serial Bus，USB)、文件传输协议(File Transfer Protocol，FTP)、超文本传输协议(HyperText Transfer Protocol，HTTP)等。
在步骤120中，根据所述升级标志确定升级，读取所述第一升级数据的地址信息。
机顶盒中通常包括有引导程序boot与升级程序loader，其中boot负责引导机顶盒启动、loader负责更新系统数据(系统升级)。本实施例中，可以是boot根据所述升级标志确定是否升级，如果确定升级，则启动loader、并由loader读取所述第一升级数据的地址信息。
在步骤130中，确定所述第一升级数据的地址信息合法，根据所述第一升级数据的地址信息从flash读取所述第一升级数据，整理所述第一升级数据，将整理后的第一升级数据按照指定规则写入到闪存(flash)中的指定地址。
第一升级数据的地址合法，即地址正确，以免写入错误的升级数据而破坏机顶盒。机顶盒的系统数据包括很多片段，每个片段存放于flash上不同的分区中，每个分区对应固定的物理地址，而这些物理地址是指定的地址，后期不能更改。指定地址可以是指当前要升级的系统数据的片段所对应的、固定不变的flash的物理地址。另外，在打包第一升级数据时可以将第一升级数据打包成不同大小的片段(每个片段可以包括多个分片)，为保证第一升级数据合法，对每个片段作CRC运算并将CRC值写入到第一升级数据中。机顶盒的系统数据分成多个片段、分布在flash上不同的分区中，每个片段只能存放在指定的分区中，而每个分区对应固定的flash物理地址。在升级时每个需要升级的片段需要完整的写入，而打包第一升级数据时已将第一升级数据打包成多个片段。从flash读取第一升级数据时，将同一个片段的多个分片数据去掉地址信息、CRC校验信息等，拼成一段完整的片段数据，然后写到该片段所对应的flash分区中。指定规则可以是指将升级数据(例如第一升级数据)中的每个片段依次写入到指定地址中时，所采用的升级数据写入的规则。
本实施例中，在机顶盒运行时，将在后台接收到的第一升级数据按指定格式写入到至少一个分区空闲地址、并记录第一升级数据的地址信息，将耗时的接收升级数据过程放到后台进行，接收完成后，进入升级应用，可根据已记录的第一升级数据的地址信息直接从flash上读取已接收的第一升级数据、并按照指定规则写入flash，完成升级。此种方式快速高效，省去进入升级应用后才开始接收升级数据等流程，实现了快速升级、减小了升级事故的发生，提高了用户的使用体验。
参考图2，本实施例提供另一种机顶盒的升级方法，可以包括如下操作。
在步骤201中，在后台实时检测升级频点是否有第一升级数据，检测到升级 频点有第一升级数据时。
升级频点可以为服务器播发的一个通道，第一升级数据通过该通道传到机顶盒中。
在步骤202中，判断是否强制升级。第一升级数据中可以包括描述当前升级是强制还是非强制的标志，根据该标志即可判断是否强制升级。
在步骤203中，在判断结果为是的情况下，则后台接收机顶盒的第一升级数据。
在步骤204中，在判断结果为否的情况下，则提示用户是否升级，确定升级后在后台接收机顶盒的第一升级数据。
在步骤205中，将所述第一升级数据整理后写入到闪存(flash)的至少一个分区的空闲地址，并记录所述第一升级数据的地址信息，写入升级标志。
在步骤206中，根据所述升级标志确定升级，读取所述第一升级数据的地址信息。
在步骤207中，判断所述第一升级数据的地址信息是否合法。
在步骤208中，在地址信息合法的情况下，根据所述第一升级数据的地址信息从闪存(flash)读取所述第一升级数据，整理所述第一升级数据，将整理后的第一升级数据按照指定规则写入到闪存(flash)中的指定地址。
在步骤209中，在地址信息不合法的情况下，接收第二升级数据，整理所述第二升级数据，将整理后的第二升级数据按照指定规则写入到闪存(flash)中的指定地址。
可选地，在实施过程中，后台接收的第一升级数据可能被破坏或不完整而不能用于升级，此时若想进行升级就需要实时的接收升级数据，也就是第二升级数据，以用于接下来的系统升级。
需要说明的是，这里的第一升级数据和第二升级数据可以是相同的，用“第一”和“第二”表示只是为了区分是后台接收的升级数据还是升级时实时接收的升级数据。
在步骤210中，升级完成，重启机顶盒。
本实施例中，所述第一升级数据的地址信息存放于flash中指定区域，所述 第一升级数据的地址信息包括升级数据、存放地址、数据长度及CRC校验信息。其中，指定区域可以是指flash中的一块存储区域(可以包括多个分区)，用于存放第一升级数据的地址信息。
本实施例中，利用多路硬件资源、开启多路后台线程接收第一升级数据，后台实时监控升级频点是否有第一升级数据，当检测到有第一升级数据时，在后台将升级数据接收下来、并整理好，进入升级应用后直接使用已整理好的数据，而无需再从头接收、整理升级数据，缩短了升级时间，减小了用户无耐心等待长时间升级、或不懂当前过程而关机导致数据被破坏、进而导致机顶盒被破坏的可能性，提高了用户体验好感度。
参考图3，本实施例提供一种换台方法，该换台方法应用于在使用上述的机顶盒的升级方法进行升级时的换台，可以包括如下操作。
在步骤301中，接收到用户的换台指令。
在步骤302中，判断是否与空中下载(OTA)升级共用资源，在不共用资源的情况下，执行步骤309。
在步骤303中，若与OTA升级共用资源，判断是否正在接收升级数据，在没有正在接收升级数据的情况下，执行步骤309。
本实施例中，所述升级数据为上述第一升级数据或第二升级数据。
在步骤304中，若正在接收升级数据，判断系统资源是否够用。
在系统资源够用的情况下，执行步骤305；系统资源不够用的情况下，执行步骤306。
在步骤305中，若系统资源够用，重新分配系统资源并换台。
在步骤306中，若系统资源不够用，提示用户正在接收升级数据。
在步骤307中，判断是否终止升级并换台，在终止升级的情况下，执行步骤309。
在步骤308中，在继续升级的情况下，终止换台并继续升级。
在步骤309中，直接换台。
可选地，该方法可以应用在可视终端中，例如电视机中。机顶盒从服务器中接收数据，并将接收到的数据转化为电视机可播放数据，使得用户可以通过 电视机观看节目。本实施例中，当机顶盒接收到用户的换台指令时，在执行该换台指令之前，可以先通过302-307中的步骤判定是否满足换台条件，如果满足，则机顶盒执行该换台指令。
本实施例中，用户换台的时候检测机顶盒的系统是否正在升级，通过检测是否与机顶盒的OTA升级共用资源及系统资源是否够用来判断是否换台，提供了一种更加灵活的换台方式，使得共用资源且系统资源够用时，系统升级和换台互不影响，提高了用户的使用体验好感度。
以下为本技术方案对应上述方法的系统的实施例，在以下系统的实施例中未详细描述的内容请参考上述方法的实施例。
