在数字视频广播(DVB)接收机中实现软件自动更新

Implementation of Software Update in DVB Receiver

在各种消费类电子产品中,软件系统一般均存在某些缺陷或需要在功能上进行修改,这就需要一种方便可靠的机制对软件系统进行升级或更新.该文设计了一种软件自动更新系统(Loader),阐述了它的工作原理,并给出了它的实现方法.该软件已经成功地应用于数字视频广播(DVB)接收机中.

In many consumer electronic products, software systems may have bugs or require necessary functional modifications. It is therefore desirable to have some convenient and reliable mechanism for software update. The design method of a software update system is presented in this paper. The principle and implementation method are discussed. The designed software has been used in DVB receiver successfully.
