  • Method for reproducing contents information in interactive optical disc device and method for providing contents information in contents provider server
    Patent number: 7881590
    Abstract: Disclosed herein are a method for reproducing contents information in an interactive optical disc device and a method for providing contents information in a contents provider server. The interactive optical disc device is connected with the contents provider server via the Internet to receive a variety of contents information provided from the contents provider server. When the sending of the contents information from the contents provider server to the interactive optical disc device is suspended or delayed due to a network connection loss on the Internet or an insufficient storage capacity of a buffer memory in the interactive optical disc device, contents information re-sent from the contents provider server and a data stream read from an interactive DVD are re-synchronized and reproduced. Therefore, a user of the interactive optical disc device can normally watch more various contents information.

  • Method and apparatus of recording digital data stream, and a recording medium containing data recorded through said method
    Patent number: 7869693
    Abstract: The present invention relates to method and apparatus of recording digital data stream on a recording medium such as a high-density digital versatile disk. The present recording method searches received digital data stream containing video signals for each picture section, packetizes a data section including at least one picture section found in the searching process into a PES (Packetized Elementary Stream) packet, slices the PES packet to make the sliced data pieces to a plurality of transport packets, and writes the plurality of transport packets within a stream object unit if the stream object unit has a space enough to store the plurality of transport packets, or from head point of a next stream object unit if not. Therefore, the head of each stream object unit is aligned with start of an arbitrary picture, thereby improving random accessibility of A/V data stream recorded on a recording medium.
