20210399913 | INFORMATION PROCESSING APPARATUS AND INFORMATION PROCESSING METHOD - There is provided an information processing apparatus and an information processing method capable of reducing a sense of delay given to a user. The information processing apparatus includes an acquisition section; an encoding section; a context recognition section; a priority data extraction section; and a communication section. The acquisition section acquires data relating to a transmission point. The encoding section encodes the data relating to the transmission point. The context recognition section sets data to be preferentially transmitted from the data relating to the transmission point on the basis of a situation of the transmission point recognized using the data relating to the transmission point. The priority data extraction section extracts the preferentially transmitted data as priority data on the basis of a setting in the context recognition section. The communication section transmits the data encoded by the encoding section and unencoded priority data to an information processing apparatus at a reception point. | 2021-12-23 |
20210399914 | METHOD AND DEVICE FOR MANAGING CONTENT CONSUMPTION IN AN EXTENDED HOME NETWORK - A device for managing an extended home network is disclosed. This extended home network comprises a main home network and a secondary network, including an equipment adapted to execute an application based on a uniform resource locator address that enables the equipment to access, via a communication network, at least one piece of data enabling the execution of the application on the equipment. The management device is configured to: receive, via the main home network, a request to associate the equipment from the secondary network with the application, store a list of equipment from the secondary network in association with the application, receive a request to launch the application, from a terminal, via the secondary network, this request comprising an identifier of the application, provide the terminal, on reception of the launch request, with the list of equipment, receive, from the terminal, an identifier of an equipment on the list. | 2021-12-23 |

20210399916 | Data Switching Device and Data Switching Method for a Vehicle, Device and Method for a Vehicle Component of a Vehicle, and Computer Program - A data switching device comprises at least one interface designed to communicate with a first plurality of vehicle components of the vehicle, and to communicate with a second plurality of vehicle components of the vehicle. The data switching device includes a control circuit designed to communicate with the first plurality of vehicle components based on at least one first data format, and with the second plurality of vehicle components based on at least one second data format. The control circuit is designed to provide a communication interface for the communication between the first plurality of vehicle components and the second plurality of vehicle components. The control circuit is designed to provide access to the first data of the first plurality of vehicle components by providing second data for the second plurality of vehicle components. | 2021-12-23 |
20210399917 | HVAC CONTROLLER AREA NETWORK HYBRID NETWORK TOPOLOGY - The present disclosure provides a CAN network topology for an HVAC communication system. The CAN network topology comprises at least three primary nodes having a predetermined termination impedance and a plurality of end nodes coupled to each primary node, wherein the predetermined termination impedance is set to the optimal setting of 180 ohms. Advantageously, the present disclosure eliminates the need for physically setting CAN node terminations. This reduces install time and removes variability of the install settings. Further, removing this variability reduces the risk for post-installation call-backs due to incorrect system setup. The present disclosure optimizes signal slew rate, which improves signal reliability. | 2021-12-23 |
