摘　　要：条件接收技术是数字电视接收控制的重要保障,它是实现付费电视与互动业务平台关键。本文简要阐述了DVB系统中的条件接收技术原理,特别是机顶盒中的条件接收技术,重点介绍基于DVB数字机顶盒中条件接收功能模块的设计及实现方法。The technology of Conditional Access is the important guarantee for Digital television Receive and control. Conditional Access is the key to realize the pay TV and interactive TV platform. In this paper we introduce the CA mechanism in DVB systems, then analyze the CA technology in Set-Top-Box. Finally, we introduce the design and implement method of functional module for CA in the Set-Top-Box based on DVB.
