  • Patent number: 10700915
    Abstract: This document describes an adaptive bitrate streaming method allowing streaming an audio video (AV) content to a client device using a multi content delivery network (CDN) approach. Each CDN stores multiple versions of a content that can be requested in the form of a succession of consecutive files using HTTP requests. The method is based on a use of an intermediate module, called diversity module, between an AV player of the client device and each CDN of a plurality of CDN. For each file of a version of a content requested by the AV player, the diversity module requests a manifest file to each CDN and estimates a bitrate of each CDN using reception performances of the manifest files. Each file is requested by the diversity module in the form of a succession of groups of segments structured according to a pattern comprising a predetermined number of segments.

  • Publication number: 20200201261
    Abstract: A dial including a mother-of-pearl wafer partially covering a support member, and a decorative element arranged on a reverse of the wafer, the decorative element being visible on an obverse of the wafer when subjected to a stimulus and invisible on the obverse of the wafer in the absence of the stimulus. The decorative element has a first empty area on a reverse of the wafer, and a second empty area on the obverse of the wafer, facing the first empty area. A colour compensation layer is deposited on the first empty area or the second empty area, the colour being selected such that the difference in colour ?E in the CIE Lab colour space between the colour compensation layer and the decorative element in the absence of said stimulus, perceived by a user observing the obverse of the wafer, is less than 3. Also, a timepiece including the dial.

  • Patent number: 10652626
    Abstract: A gateway connects a first communication network comprising at least one terminal intended to consume multimedia contents and a second communication network via which the gateway is intended to receive the multimedia contents in a stream form. The gateway detects (400) a use of a unicast connection intended for transmitting a multimedia content from an original server to a terminal of said network via the gateway; seeks (403) a connection redirection rule according to information exchanged by the original server and the terminal; establishes (406) a multicast connection in order to receive the multimedia content; receives (407) the multimedia content in the form of a stream according to the multicast connection; and transmits (409) to the terminal the multimedia content in the form of a stream according to the unicast connection.

  • Patent number: 10586364
    Abstract: Embodiments herein disclose methods and systems for decorating and embellishing interstitial space in a digital object layout using one or more design elements. Embodiments herein place one or more embellishments on any layout of 1-dimensional objects in a sequential manner by automatically detecting one or more “potential” regions/locations of placement (computed rectangular whitespace on edge, computed rectangular whitespace inside, geometric corners/vertices). One or more embellishments are placed in the one or more determined regions/locations using aesthetic measurements (measurement of nearest and furthest neighbor, chamfer radius around corners, number of objects overlaid on one side against the number of objects overlaid on the other side) and a rule based system. Embodiments herein disclose one or more specific design rules that enable a layout with embellishments to look aesthetically pleasing.

Each group includes one set of segments for each CDN, each set including segments to be requested to the CDN to which they correspond proportional to the bitrate of this CDN.

  • Patent number: 5105874
    Abstract: According to this process: the position in respect of height of the "molten metal (2)/liquid slag (3)" interface (M) is continuously determined. Further the position of an isotherm (IS) located at the "liquid slag (3)/powder layer (4)" interface is continuously determined by automatically controlling the position of a thermocouple (8) on this isotherm and by measuring the displacements of this thermocouple.By comparing the position in respect of height of the molten metal/liquid slag interface (M) with the position in respect of height of the isotherm (IS), the thickness and thus the variations in thickness of the liquid slag are continuously deduced.

  • Patent number: 4369834
    Abstract: The invention has for its object a process for recovering heat from a hot gaseous current, wherein it consists in making the hos gaseous current travel countercurrent to colder solid particles comprising at least a stage made up of a stack of packing elements placed on a widely perforated support, then distributing them at the top of a second column, letting them fall countercurrent to a second colder gaseous current while their grain-from-grain separation, to recover the heat of the solid heated particles.The invention also proposes a device for using the process.
