Description

基于DVB多终端节目播放方法及系统、机顶盒及移动终端 技术领域
本申请涉及机顶盒应用领域，尤其涉及基于DVB多终端节目播放方法及系统、机顶盒及移动终端。
背景技术
随着数字电视的不断发展及深入，数字电视机顶盒在家庭中普及程度越来越高，用户对机顶盒的需求也不断差异化的发展：
用户对家庭中第二台机顶盒的需求不断增强。但是运营商在面对家庭中第二台机顶盒的需求上则踌躇不前。一方面，用户不愿意在一个家庭中支出两份收视费。另一方面，运营商面临家庭中第二台盒子的管理及硬件成本投入增加的实际困难。现有的做法是通过子母卡实现家庭中第二台机顶盒的收视，第一，需要用户或运营商采购第二台机顶盒及智能卡。第二，为防止第二台机顶盒流到其他家庭中，运营商需要不定时通过母卡激活子卡。
随着以手机为首的移动终端的不断发展，用户对通过手机、PDA等移动终端收看电视节目的意愿越来越强烈。但是通过Internet收看电视节目存在着节目源版权、实时性、网络带宽等条件的限制。
由于技术水平及硬件条件的限制，移动端无法集成机顶盒领域现有的条件访问系统(Conditional Access System，CAS)系统解扰，所以，对于加密节目，通用的做法是：1.在机顶盒端将节目解密。2.将解密后的音视频数据发送到移动端解码播放。
在多终端上播放数字视频广播(Digital Video Broadcasting，DVB)机顶盒的节目源，节目内容的保护是首先需要考虑的问题。如果通过较为简单的技术手段，即可以获取解密后的音视频数据，则相当于破解了运营商的CAS系统，这是运营商不愿意看到的后果。
