  • Patent number: 7489854
    Abstract: A recording medium with the increased recording efficiency is provided. Depending upon the size of the remaining area of a sector, a transport stream unit is recorded across two sectors with the result that sectors contain no null data. If the size of the remaining area of the last sector of a stream object unit is less than the size of a transport stream unit, the remaining area is padded with null data.

  • Patent number: 7454125
    Abstract: An apparatus and method for creating and recording management information for searching recorded digital data streams is described. When a digital data stream is recorded on a recording medium, index information for pointing to the location of the time information corresponding to the first stream object unit of each stream object on a time information table is created and recorded. Alternatively, the index information contains the number of start stream object unit for the selected stream object. When reproducing or searching the recorded digital data stream, a stream object is found using the time information of stream objects and the recording location corresponding to a requested search time is found using the index information.

  • Publication number: 20080152304
    Abstract: The present invention relates to multi-channel stream recording/reproducing method and apparatus. The present multi-channel stream reproducing method checks whether or not reproduced multi-channel stream belongs to same broadcast (RF) channel, and deletes PSI (Program Specific Information) packets included in channel stream excluding one channel stream if it belongs to same RF channel, and makes new PSI packets with reference to PSI packets included in reproduced multi-channel stream to replace them, if not. Furthermore, the present method compensates appropriately PCRs (Program Clock References) included in channel stream excluding one channel stream in case of the latter. The present method enables a digital TV set to present multi-channel stream simultaneously in PIP (Picture-In-Picture) or multi-screen mode with no error in channel selection and presentation (or decoding) time.

  • Patent number: 7366402
    Abstract: 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.

  • Patent number: 7280742
    Abstract: The present invention relates to a method of writing audio data to a rewritable recording medium as grouping the written audio data into each Audio Object Unit (AOBU). This method changes AOBU grouping criterion such as time or size if a bit rate of input audio data being written to the rewritable disk is changed, and groups written audio data into each AOBU in accordance with the changed AOBU grouping criterion while recording. As a result, an amount of management information to be created for each AOBU is reduced remarkably even if the bit rate of input audio data is relatively low.
