    摘要: The present invention relates to a method and apparatus of recording a directly-received digital television broadcast signal. This method demodulates a received high definition digital television broadcast signal, extracts transport stream belonging to a chosen channel among the demodulated data stream, analyzes data of the transport stream, extracts and creates data stream- and/or recording-related information, and writes the data stream- and/or recording-related information and the extracted transport stream to a recording medium in a format suitable to the extracted and created information. According to the present method and apparatus, it is possible to record a high definition digital television broadcast signal without any intermediary set top box to a high-density recording medium in the appropriate recording format as well as to conduct a trick play for recorded television broadcast signal smoothly with such recorded format and the data stream- and/or recording-related information.

    摘要: The present invention relates to a method of recording still pictures and audio data onto a rewritable recording medium. The present method records still-picture video and audio files of the recording format of a digital till camera under a subdirectory of a DCIM (Digital Camera IMages) directory of DCF (Design rule for Camera File system) and still-picture video and/or audio files of the recording format of a disk video recorder under a subdirectory of a moving-picture directory, creates management information for searching and presentation control of the still-picture video and audio files below the DCIM directory and the still-picture video and/or audio files below the moving-picture directory, and records the created management information under another subdirectory of the moving-picture directory. Thus, efficient and convenient file management is possible through a single recording medium, which results in remarkable improvement of use convenience of a motion picture recorder and a digital still camera.
