摘要:
阐述了上海轨道交通移动电视现有应用方案面临的成本、服务质量、运营信息加载等问题。结合上海轨道交通车地传输系统应用情况与系统特点,从通信带宽、系统定位、电磁干扰、实施难度、业务扩展等方面分析,并提出了3种移动电视业务承载方案。经比选,上海轨道交通自有的地铁移动互联网系统(MMIS)是符合现阶段上海轨道交通移动电视应用和业务可持续扩展的最优应用方案。
Abstracts:
The present application scheme of mobile TV adopted by Shanghai rail transit is facing problems like cost, service quality, operation information loading and so on. Considering the application situation and characteristics of vehicle-to-ground communication system in Shanghai rail transit, the communication bandwidth, system location, electromagnetic interference, implementation difficulty, service expansion and so on are analyzed, three business loading plans are put forward. Through comparison, the MMIS(multimedia management information system)adopted Shanghai rail transit is regarded as the optimal application scheme, it is in line with current mobile TV application and sustainable service expansion in Shanghai rail transit.
