    Abstract: A data storage system having an intermediary server including an input interface, a memory and an output interface. The input interface configured to establish, via one or more programmatic interfaces, a connection with a client device to receive data for upload to a storage server and measure an input rate of the data received from the client device. The memory configured to store the data in a buffer as the data is received. The output interface configured to establish a connection with the storage server, determine an output rate for sending the data from the buffer to the storage server based at least in part on the input rate and a timeout value for the storage server, and send the data from the buffer to the storage server at the output rate.

  • Patent number: 11494445
    Abstract: A method for data storage tape access ordering is provided. The method receives an order request for accessing a plurality of data segments stored on a data storage tape. Each data segment is defined by segment characteristics. The method identifies a number of data segments within the plurality of data segments in the order request. The method determines an order model based on the number of data segments and the segment characteristics of the plurality of data segments. The method generates an access order for the plurality of data segments based on the order model and retrieves a subset of data segments from the data storage tape based on the access order.

  • Patent number: 10893528
    Abstract: According to one configuration, a base station controller monitors use of multiple wireless channels amongst multiple wireless base stations operating in a wireless network environment. In response to detecting under allocation of wireless channels between a first wireless base station and a first group of communication devices, the base station control allocates a supplemental wireless channel to the first wireless base station. In one embodiment, the base station controller de-allocates a wireless channel from a second wireless base station and assigns the de-allocated wireless channel to the first wireless base station as the supplemental wireless channel. The base station controller then transmits a channel allocation communication to the first wireless base station, the channel allocation communication indicating an identity of the supplemental wireless channel allocated for use by the first wireless base station.

  • Patent number: 8737811
    Abstract: A playback device that secures coexistence of a built-in GUI for a built-in machine created uniquely by the manufacturer and a stereoscopic image created by the contents provider. A subtitle decoder displays a subtitle in a predetermined layout by decoding a subtitle stream. A GUI processing unit draws the built-in GUI. The layout of the subtitle to be displayed is one of: normal layout in which areas for subtitle display are provided both in upper and lower parts of a screen; top arrangement layout in which an area for displaying subtitle is provided only in the upper part of the screen; and bottom arrangement layout in which the area for displaying the subtitle is provided only in the lower part. When the top or bottom arrangement layout is selected as the layout of the subtitle, the GUI processing unit selects the layout of the subtitle as the layout of the built-in GUI.

  • Patent number: 8630159
    Abstract: In a multilayer optical disc having information layers conforming to a plurality of different optical disc standards, because the type of each information layer is not recorded in the other information layers, every time the information layer being accessed changes, it has been necessary to read the type of the information layer and select a method of generating a tracking error signal adapted to the type of information layer, so access has taken time. In order to solve the above problem, in the optical multilayer disc according to the present invention, having information layers conforming to a plurality of different optical disc standards, in an area in one of the information layers, information about the other information layers is recorded. The time required to access the other information layers can be reduced by using this information to select a tracking error signal generating method.
