It is given out that a multi - agent model of data broadcasting information platform and an agent model of self - maintenance for the information service hardware , and it is demonstrated and analyzed in detail 提出了数字广播信息平台的多智能体模型及信息服务硬件平台自维护的智能体模型，并进行了详细的论证和分析。
In general , the implementation of the scheme proposed in this paper will ultimately contribute to the realization of multimedia services such as vod , high speed dvb data broadcasting and conditional access system 本课题的实现与完善，将为视频点播， dvb高速数据广播，条件接收等多媒体业务的实现提供必要的技术基础。
With the develepment of the data broadcast , there must have a system can help customer to select what his want from the giant information . we put forward this project to meet this demand 随着数据广播业务的开展、广播数据类型和数量的增长,需要有一个系统帮助用户从大量的信息中选择和抽取自己所需要的信息,本项目就是为满足这种需求所提出来的。
On the digital broadcasting television network , we could realize not only the traditional television service , but also a lot of new additional services , such as vod , ppv , online games and data broadcasting 在数字广播电视网上,不仅能实现传统的电视业务,还可以衍生出多种新的增值服务,如视频点播( vod ) 、按次付费( ppv ) 、网上游戏、数据广播等。
The high - speed data broadcasting system is compatible with almost all existing standard catv equipments and can be applicated to networks including the national state or the 1ocal without changing the existing network 该系统在不改造现有网络的基础上，与目前绝大多数标准的有线电视传输设备兼容，可应用于覆盖全国、各省市、地市以及县区乡镇的有线电视网络。
Therefore , the research of information transmission platform using the ip network will be effectively combined with the data broadcast network and provide reliable services to the users will produce great social and economic benefits 因此，研究能有效结合ip网络与数字广播网络的资源、为广大用户提供可靠服务质量的信心传输平台具有非常巨大的社会和经济效益。
For a power plant , the database has its own property , so proper method is needed to access such database . the data of power plant is time - sensitive , an efficient data broadcasting system is very important to implement remote monitor of the power system 传统的水电厂数据库访问方式为客户端服务器模式，此种模式有其不可克服的缺点，会逐渐被浏览器朋艮务器模式所取代。
