  • Publication number: 20080145021
    Abstract: In a video recording apparatus which records and reproduces digital TV broadcasting, an I-picture extraction processor that extracts packets containing I-pictures by analyzing a transport stream is arranged. Then, packets containing I-pictures is output, by reading predetermined amount of recorded data from an HDD in which recorded data is stored and by detecting start information and end information of the I-pictures. A stream for special reproduction is output by repeating the above-stated processes. With such arrangement, it is possible, even if data does not contain position information of I-picture, to execute special reproduction such as fast-forwarding reproduction for TV program data that is recorded as an MPEG-formatted transport stream.

  • Publication number: 20070079343
    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.
