DVB-S机顶盒中自维护引导装载系统的设计与实现

摘要

通过分析基于卫星数字视频广播的电视机顶盒使用过程中软件维护与升级中存在的问题，提出一种自维护引导装载系统的设计．并给出该设计的软件体系结构与实现方法。实际应用表明，该设计提高了机顶盒软件的自动维护和恢复功能．保证机顶盒在运行过程中具有较强的健壮性。%Through analyze the problems in the software maintenance and upgrades which existing in satellite digital video broadcasting TV set-top boxes, a self-maintenance bootloader design was proposed and software architecture and implementation was be given. The application shows that the design increases the maintenance and recovery of the set-top box software and it guarantees the strong robustness in the set-top box running.
