摘　　要：本文面向省、市、县三级村镇建设用地再开发管理部门,针对带宽受限和传输数据容量大的矛盾,探讨了3G数据传输过程中的传输网络方案。在调查村镇建设用地再开发监管过程对数字化监管平台需求的基础上,结合我国村镇网络设施受限、多数地区存在Wi Fi网络无法覆盖的实际情况,选择了3G无线传输网络和H.264视频压缩编码标准。针对村镇建设用地再开发实际监管和监管系统视频传输的过程中存在的问题,分别探索了视频本地存档、异地调用的双码流传输方式和带宽受限条件下异步传输、可伸缩编码和视频画面切割的传输方案。本文研究村镇建设用地再开发现场监测技术,为村镇建设社会主义新农村再开发现场监测、全程监管、县市省三级互通互联与公共服务、以及信息化监管技术平台的构建提供理论基础。This paper is for the administration of redevelopment of towns' construction land in three-level of county, city and province. The core issue of this paper is to resolve the contradiction between limitation of bandwidth and high capacity of data transmission. First, the author in this paper surveys the demand of supervisory platform of digitization for supervised process of redevelopment of towns' construction land. Second, the author chooses 3G as video wireless transmission network and H.264 video compression encoding standard is based on the truth that the limitation of towns' network facilities and the Wi Fi can't cover the majority of district in our country. Last, the author explores the dual-stream transmission mode and transmission plan of asynchronous transmission, extension-type encoding and video frames cutting in the condition of bandwidth limited. This study provides the theory foundation for the project of wireless video surveillance in locale of redevelopment of towns' construction land.
