背景技术
随着全球数字化步伐的推进，机顶盒已经成为现代人们生活中不可或缺的媒介，伴随着大数据时代的到来，机顶盒技术也在不断的更新着。然而，机顶盒付费节目的支付主要还是通过条件接收(Conditional Access，CA)***付费，以及通过电子账户支付费用。
但相关技术中的机顶盒付费方式存在以下缺点：1.当CA卡内余额不足的时候，需要用户前往运营商的营业中心或者拨打客户中心服务电话，实时性响应比较差；2.电子账户余额不足时则需要在电脑或者手机应用上手动往银行卡中转账续费，操作略微麻烦。而且很多时候续费是针对节目包的，没有针对单个视频节目的操作，灵活性不够。同时以上两种付费方式还存在着账户与机顶盒绑定的情况，消费时必然会存在身份认证等操作，比如酒店的顾客和租户使用的分别是酒店的机顶盒和房东的机顶盒，想要观看一些付费节目的话就比较麻烦。

在步骤210中，机顶盒接收到用户的节目播放请求。
机顶盒接收到用户的节目播放请求之前，所述方法还可以包括：
前端***通过EPG***和CA***中的至少一个将节目的统一资源定位符(Uniform Resoure Locator，URL)地址通过广播网络推送给机顶盒；以及
机顶盒利用所述URL地址通过网络获取节目信息，通过菜单或浏览器的方式在输出设备上呈现给用户。
带网络通信功能的机顶盒利用二维码支付观看节目的方法可以包括：运营商收集有价值的视频源(比如新发布的好莱坞影片、音乐短片(Music Video，MV)等)放到服务器上，并通过前端***将视频源的URL地址广播推送给机顶盒。该推送消息可以通过多种途径进行：
A)通过前端EPG***推送：在业务群关联表(BouquetAssociation Table，BAT)中定义一个特定节目组，并在特定节目组的私有描述子里面描述URL等；

利用SSL证书对所述节目的密钥的传输信道进行加密，利用私有加密算法对所述节目的密钥进行加密，通过解密的传输信道把所述加密的密钥发送给机顶盒。
前端***接收到所述支付二维码的支付信息，发送所述节目对应的密钥给机顶盒。由于密钥是用于对节目进行解密可以对密钥采取保护措施。可以通过对传输信道进行加密保护、对密钥本身进行加密保护、或同时对传输信道和密钥进行加密保护的方式对密钥进行保护。对传输信道进行加密可以确保密钥的传输不会被修改和窃听，确保数据的保密性。对密钥本身进行加密保护，可以利用私有加密算法对密钥进行加密，即使密钥在传输过程中被非法监听，监听者也无法获取到明文的密钥，不能对节目进行解密，不能观看节目。所述私有加密算法可以包括软件加密方式和基于硬件的硬件加密方式，其中，软件加密方式适用于普通安全强度的环境；基于硬件的硬件加密方式是一种高强度的加密方式，黑客破解需要几年甚至几十年的时间。其中，私有加密算法可以是运营商自定义的加密算法。
在步骤260中，机顶盒获取节目数据，利用控制字完成节目数据的解密，并播放解密后的节目数据，其中，所述控制字根据所述密钥得到。
可选的，机顶盒通过因特网获取节目数据，根据所述密钥得到控制字，将所述控制字设置到解扰器中，完成对节目数据的解密，将节目数据送入解码器中，完成解码和播放工作。
基于上述的密钥保护机制，所述机顶盒获取节目数据，利用控制字完成节目数据的解密，并播放解密后的节目数据，可以包括：
机顶盒获取节目数据，接收前端***发送的密钥，从所述密钥中得到明文的控制字，将所述控制字设置到解扰器中，完成对节目数据的解密，并播放解 密后的节目数据；或

机顶盒获取接目录数据，接收前端***发送的通过硬件加密方式加密的密钥，通过硬件解密得到明文的控制字，所述控制字由硬件传送到解扰器中，完成对节目数据的解密，并播放解密后的节目数据。
其中，通过硬件解密得到明文的控制字的这种方式中，用户接触不到明文的控制字，安全系数大。
本实施例基于带网络通信功能的机顶盒，运营商可以通过前端***推送点播节目信息，经由网络传输给机顶盒，用户通过人机界面交互后点播节目，前端***生成支付二维码，用户通过移动终端扫描二维码，确定支付后，机顶盒与前端***进行数据交互，用户可以观看点播的节目。本实施提出的节目支付二维码的模式，通过因特网获取节目支付二维码和节目数据，用户可以随时随地地观看节目，不限定在一个机顶盒，不需要购买整个节目包，用户针对单个节目付费即可，灵活性强。使用二维码移动支付手段，用户通过扫描二维码进行支付，贴近用户的消费习惯，付费方式便捷。
