摘　　要：目前新一代直播卫星电视机顶盒在安装开通时,前端系统会将圆形围栏随收视授权下发到机顶盒,机顶盒正常收视时依据圆形围栏开展位置判断,若超出围栏则进行信息提示和关断授权等处理。鉴于维护广播电视市场传播秩序考虑,圆形围栏范围较窄。这种情况造成了机顶盒安装开通和设备移机存在不够便利的情况。本文提出了一种在终端存储地图电子围栏的自主定位机制,能够同时满足精准管理和精细服务的要求。At present,when the new generation of live satellite set-top box is installed and opened,the front-end system will send the circular fence to the set-top box along with the audience authorization.When the set-top box has a normal viewing,it will judge the position of the circular fence.If it exceeds the fence,it will conduct information prompt and turn off the authorization.As a result,the installation and opening of the set-top box and the transfer of equipment are not convenient enough.This paper proposes an autonomous positioning mechanism for storing map electronic fence in terminals,which can meet the requirements of accurate management and fine service at the same time.
