Abstract: A digital broadcast receiving/recording/reproducing device records and reproduces input streams in and on a recording/reproducing device, simultaneously records two streams, and reproduces one stream while reproducing the other recorded stream at the same time, thereby the streams can be viewed. The digital broadcast receiving/recording/reproducing device of the present invention extracts a distinctive part of video or audio data to be recorded, processes other video or audio data to be recorded at the same time in association with each other, creates a management file for processing information regarding the associated data, and records the created file together with the video or audio data to be recorded in a recording section. Then, the digital broadcast receiving/recording/reproducing device controls whether to reproduce the recorded video or audio data recorded based on the information of the management file.
