电信运营商专用视频内容分发系统是未来承担智能电视视频分发的主力，但急剧上升的成本严重制约电信运营商视频内容分发系统的可持续发展。针对该情况，从成本控制角度对电信运营商视频内容分发系统的分发策略进行评估。提出成本相关的评估指标和相关参数，以上海电信网络电视系统为例分析实际用户行为，构建大规模视频内容分发仿真系统，进行大量仿真实验。实验结果展示了评估指标和相关参数间的定量关系，该分发策略能够使系统成本最小，为电信运营商选择内容分发策略提供理论依据。

Telecom operators ’ special video content distribution system may become the main-stream video content distribution system for smart TV. In order to ensure continuing development of telecom video content distribution system, this paper evaluates content distribution strategies from the perspective of cost. It proposes cost-related metrics and primitives,builds actual user behaviors model of Shanghai Telecom Interactive Personality TV ( IPTV ) system, and implements a large-scale simulation system of telecom video content distribution system and conducts some simulation experiments based on actual user behaviors. Experimental results show the quantity relationships between metrics and related parameters,and get the optimized distribution strategy which minimizes the cost. This paper contributes to the telecom operators’ decision-making in choosing distribution strategies and setting parameters.
