    摘要： The present invention relates to a method and apparatus for transceiving audio data reproduced from a recording medium such as a digital video disk (DVD) through a digital interface such as IEEE 1394. The transmitting method according to the present invention separates an audio data stream from data reproduced from a recording medium, inserts the separated audio data stream into the private data area of an MPEG-formatted data stream, and transmits the MPEG-formatted data stream containing the audio data stream in the private data area through a digital communication line. The receiving method according to the present invention checks whether or not an MPEG-formatted data stream received through a digital interface includes the private data area, extracts audio data inserted in the private data area, and decodes the extracted audio data. As a result, the present invention does not require the conventional re-encoding process after decoding. Therefore, the present invention prevents possible loss of audio data such as LPCM audio data caused from the re-encoding operation as well as reduces device cost.

    摘要： Method and apparatus for recording digital data transport stream units such as application packets in sectors of a disk type recording medium such as a digital versatile disk and create and record management information for the recorded transport stream units. In case that a single transport stream unit is divided and then recorded across two sectors, header information of the preceding sector including management information which is created corresponding to each transport stream unit is generated, and the size of the header information and transport stream units to be recorded in the preceding sector is compared with the size of a sector. If the size difference is 1 byte, an invalid header data distinguishable from normal application header extension information is inserted to maintain the correspondence between each transport stream unit to be recorded in the preceding sector and its management information.

    摘要： 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.

    摘要： A recording medium according to an embodiment includes a recording layer and a transport stream recorded on the recording layer. The transport stream is composed of one or more predetermined units, each predetermined unit starting with at least one transport packet for carrying navigation information used to manage subsequent transport packets. The first packet of the at least one transport packet carries only the navigation information including program clock reference (PCR) information and does not carry presentation data.
