  • Patent number: 10623690
    Abstract: Each of multiple cameras encodes and transmits a video signal captured, the encoding being performed with one of multiple variable bit rate encoding schemes each of which has a different average bit rate. A receiving device periodically measures the total bandwidth of the video signals received from the multiple cameras, and when the total bandwidth exceeds a first threshold value the receiving device switches the encoding scheme used by the cameras to a scheme having a lower average bit rate. In addition, when the total bandwidth falls below a second threshold value that is equal to or less than the first threshold value, the receiving device switches the encoding scheme used by the cameras to a scheme having a higher average bit rate.

  • Patent number: 9014531
    Abstract: A transmitting section of the present invention initiates transmission of a second video continuously after completing transmission of a first video being transmitted, in a case that a reproduction position of the first video being transmitted is beyond an end point of the first video, when a video recording start time of a second video stored in a video storage section and a video recording end time of the first video being transmitted coincide within a predetermined time difference.

  • Patent number: 8595779
    Abstract: A base server apparatus of the present invention includes a data distribution control unit for receiving a pause request signal that requests to pause playing the data from a terminal, and a data accumulation unit for starting to record data transmitted from a distribution center after receiving the pause request signal. The data distribution control unit includes a distribution unit that transfers the data transmitted from the distribution center to the terminal not requesting to pause playing the data, and if a resume request signal requesting to resume playing the data is received from the terminal requesting to pause playing the data, the distribution unit distributes the data recorded in the data accumulation unit to the terminal.

  • Patent number: 6458902
    Abstract: Disclosed is a process for preparing a hydrogenated C9 petroleum resin, the process comprising hydrogenating a C9 petroleum resin obtained by polymerizing polymerizable monomers of a C9 fraction using a non-phenolic Friedel-Crafts catalyst in the presence or absence of a non-phenolic molecular weight modifier. The hydrogenated C9 petroleum resin obtained according to the present invention retains the characteristics of known hydrogenated C9 petroleum resins and has high thermal stability, good light resistance, and remarkably low fluorescence.
