联网接入架构
县（市、区）在纳税服务内部网络内部署建设视频接入平台，用于接入的视频监控资源。
市级视频接入平台级联各县级视频接入平台，可管理、监看本市的单位视频信息。
省级视频接入平台级联各市级视频接入平台，可管理、监看全省的单位视频信息。
各级平台应搭建于具备固定IP的互联网环境下，兼顾经济性与多用户同时使用的需求，平台网带宽应不低于50M。
Network Access Architecture
The County (city, district) deploys a video access platform within the internal network of tax payment service, which is used to access video surveillance resources.
The city-level video access platform cascades all county-level video access platforms, which can manage and monitor the video information of the city's units.
The provincial video access platform cascades all city-level video access platforms, which can manage and monitor the unit video information of the whole province.
Platforms at all levels should be built in the Internet environment with fixed IP, taking into account both economic and multi-user needs, and the network bandwidth of the platform should not be less than 50M. (2019-05-06, C/C++, 316KB, 下载1次)
该系统支持具有IPTV交互特点的课后练习、测试以及答疑等学习活动，可以使传统远程教育系统告别单一被动的节目接受，走向集在线学习、游戏娱乐、生活服务于一体的更为丰富多彩的互动数字化教育，并有效解决实时课堂传输中视频质量的问题，以及随着用户数目的聚增而产生的网络带宽瓶颈等问题。该系统主要由EGP用户显示界面、频道产生器和数据库等部分组成，主要以Visual Studio 2005作为开发工具，用SQL Server2000实现数据库部分，具有技术先进、操作简单、成本低等特点，更加适用于村镇中小学教育、党员教育、社区教育和教师培训等各种形式的远程教育教学活动。
To address the above problems, this thesis argues that developing a IPTV-based educational network service system in a new sense，which integrate the P2P technology and streaming media technology as a major support. This system will support many learning activities, such as after-school practice, testing, qustion and answer, which have interactive features with IPTV. It also means that the traditional distance education system program will say goodbye to passive and single, and become to more variety, which including online learning, entertainment, life service and so on. At the same time, this system could effectively solve problems about video quality in real-time classroom transmission, and network bandwidth bottlenecks that bring about by increasing of the customers number. This system mainly conclude three sections: EGP user interface part, Channel Generator and data base. We choose Visual Studio 2005 as a development tool, and use SQL Server2000 database to accomplish it’s functio (2010-04-06, Visual C++, 1764KB, 下载39次)
