Abstract: A recording apparatus configured to receive analog video and audio signals, digitize and compress the same, and record the compressed audio and video signals on a digital recording medium such as an optical disk. As the audio and video signals are received and recorded, time segments of the audio signals are analyzed for certain features such as whether the time segment corresponds to instrumental music, vocal music or conversational speech. A table of contents is then generated corresponding to the feature analysis and digitally stored on the storage medium. As a result, the recorded audio is characterized over time, e.g., on a frame by frame basis. A high degree of versatility is thereby provided in the playback process, such as the ability to skip portions having certain audio types or to quickly scroll to desired portions of the recorded audio programs. Reproducing apparatuses enable the user to selectively reproduce segments of the recorded audio and video.
