In U-city(Ubiquitous City) environment, many types of real-time video data can be implemented in varied cases. For instance, the mobile user device can be in difficult environment to communication. When real-time streaming, it is necessary to ensure stable streaming and minimizing data loss rate. Unbreakable real-time video streaming is need to escape these environment or save distressed people. It needs that network adaptive real-time streaming to ensure real time streaming. In most case

It can ensure real-time video streaming and scalability of transmission by control variable quantization parameter. In this paper, we describe and suggest continuity real-time streaming technique that adaptive to network condition for U-city environment. And it can support varied user device in intelligent ubiquitous middleware Smart UM. And it also can ensure continuity of real-time video streaming. The adaptive streaming system can also applied to varied many other systems.
