In korea, TIT(Transport Information Technology) based IP-TV services have been provided in Saemaeul trains and some sections of subway trains, But the software systems for the service performed in alternated fashions and suffered from many problems such as suspension, memory leaking and overflow, These problems increased playback loss time and resulted in bad reliabilities, In this paper, a software TIT monitor is designed and implemented for Monitoring module and Reset module in physically poor environments, The designed system formalized monitoring time intervals for effective monitoring, Through the real experiments, playback time is improved in 7.2% comparing to existing system.

Since the DirectTV started its digital broadcasting services in 1994 for the first time in the U.S., digital broadcasting widened its services in many areas. In korea, TIT(Transport Information Technology) based IP-TV services have been provided in Saemaeul trains and some sections of subway trains. But the software systems for the service performed in alternated fashions and suffered from many problems such as suspension, memory leaking and overflow. These problems increased playback loss time and resulted in bad reliabilities. In this paper, a software TIT monitor is designed and implemented for the TIT system in physically poor environments. The designed system formalized monitoring time intervals for effective monitoring. Through the real experiments, playback time is improved in 14% comparing to existing system.
