  • Patent number: 7613839
    Abstract: A method is disclosed for setting a master node of a ring network that has adjacently connected nodes situated on rightward and leftward lines of a bidirectional transmission channel. The method includes the steps of: counting the number of nodes interposed between a designated node and each node other than the designated node on the rightward and leftward lines of the bidirectional transmission channel; and setting one of the nodes as the master node. The master node satisfies a relation of, NHC_L=NHC_R or NHC_L=NHC_R-1, wherein NHC_L is the number of interposed nodes counted from the leftward line, and NHC_R is the number of interposed nodes counted from the rightward line.

  • Patent number: 5991503
    Abstract: An encoding unit encodes and compresses picture data in a bit map format corresponding to the MPEG method. A packet assembling portion assembles the picture data encoded by the encoding unit as packets in the format corresponding to the MPEG method, and stores the packets to a storing medium. At this point, the packet assembling portion writes an I picture index to a packet that contains at least a part of I picture data. When a special reproducing operation is performed, a data storing unit reads only packets that have the I picture index. A decoding unit decodes only I picture data of picture data contained in packets read from the storing medium and displays the decoded picture data.
