Design, implementation and evaluation of data carrousel extractor algorithm on MPEG-2 TS for digital terrestrial television

This paper shows the design, implementation and evaluation of an algorithm that allows the extraction of Transport Stream's (TS) data section for Digital Terrestrial Television (DTT), with the organization in a hierarchical file system and directories based on MPEG-2 standard ISO-13818-6: Extension for Digital Storage Media Command and Control (DSM-CC), in order to fully recover the media from interactive applications contained by the MPEG-2 TS stream. To check the validity of the algorithm, it was implemented in a software to evaluate the application extraction of different TS, verifying its correct operation, as it successfully recovered all directories and files from interactive applications.
