Methods and apparatuses for recording information on and reproducing information from a recording medium and the recording medium

Abstract

The present invention relates to method for recording program specific information (PSI) for a recorded data stream in an optical disk such as a high-density digital versatile disk (HD-DVD) and providing the recorded PSI to a presenting device such as a digital television. This method writes program or stream specific information in a management data recording area of a high-density disk, and when the recorded data stream is reproduced, determines whether it is time to send the stream specific information, obtains stream specific information corresponding to a stream object being reproduced, or to be reproduced based on the determination result, and transmits the obtained stream specific information. This method can maintain the disk storage capacity for real video and/or audio data by recording stream specific information in a management recording area of a high-density disk, and provide the stream specific information to a digital television promptly when it is necessary, thereby reducing the time duration of blank screen or discontinuity in video and/or audio presentation.The methods and apparatuses record information on or reproduce information from a recording medium. The information includes at least video information and presentation control information for managing presentation of the video information. The presentation control information includes change information for the video information, and the change information indicates a point in the video information where at least a portion of the presentation control information for the video information changes.
