Abstract
Disclosed are a system and method for providing digital multimedia broadcasting confinement service. The system includes: a relay center side system, which is adopted to the relay center, according to the relay center side packet identification description (PID) key, for modifying the PID of transport stream and generating the distorted program specific information (PSI); and a terminal side system, which is adopted to the DMB terminal, according to the terminal side PID key, for recovering the distorted PSI of the transport stream received from the relay center and decoding it. The method includes the steps of: identifying whether the actual PID of the TS is consistent when the TS is demultiplexed by audio/video PID acquired through the program map table (PMT) analysis of the TS; generating a preset alarm signal; modifying the PID of the audio/video data in the PMT according to the terminal side PID; and demultiplexing the TS according to the modified PID value.
