Abstract
In the general recording method of mobile broadcasting, all incoming broadcasting streams after recording time will be saved regardless of its content. In this case, as such that viewers do not want to record, commercial advertisement, are saved together. In order to solve these problems, the proposed method checks if the contents such as advertisements are exist in the target stream by analysing the splicing in incoming MPEG-2 TS streams and, if splicing happened, excludes incoming stream after the splicing in the recording process. In the proposed method, first the splice in the recording stream is verified using the related flags of adaptation field in the TS packet and, if judged to cause a splice, the time of splicing is to be estimated by evaluating the value of splice_countdown filed. In this way, the proposed algorithm provides the seamless recording method by estimating the time of splice and excluding the contents after the splicing. To evaluate the proposed seamless recording method, the simulation was carried out by modifying the software of the existing mobile broadcasting terminal.
