A method comprising: obtaining an outbound message, the outbound message being an application-layer message; generating a plurality of first fingerprints based on the outbound message, each of the first fingerprints being generated based on a different portion of the outbound message; detecting, based on the plurality of first fingerprints, whether a first cached message is stored in a memory that matches the outbound message; when the first cached message is stored in the memory, including an identifier of the first cached message in the outbound message, replacing a first region of a payload of the outbound message with a first token, the first region of the payload of the outbound message including a sequence of bits that is also found the first cached message, and transmitting the outbound message to a remote device.

Systems and methods for scheduling environment perception-based data offloading for numerous connected vehicles are disclosed. In one embodiment, a method for offloading data includes capturing an image of a view of interest from a vehicle, segmenting the image into a plurality of blocks, and determining a scheduling priority for each of one or more blocks among the plurality of blocks based on block values, wherein the block values relate to one or more objects of interest contained in each of the one or more blocks. The method further includes offloading, from the vehicle to a server, one or more blocks based on the scheduling priority of the one or more blocks.

Header compression/decompression profiles are stored in a central registry, or database, and provided on demand, on initialisation of a new device, from time to time, or otherwise, to gateways communicating with one or more endpoints in accordance with the profile in question. The profile to be retrieved is selected on the basis of an identity value included in a message transmitted from the endpoint. The identity may be unique to a particular endpoint, or a type or class of endpoints using a particular profile, or correspond directly to the profile, or otherwise. Distributed registry structures, possibly including private and public registers, are proposed. Different classes of information may be associated with each profile, which may be subject to varying degrees of protection, and or varying access conditions.

A system for on board diagnostic (OBD) vehicle communications that includes a vehicle communications device having a pin-connector adapted for connecting to a vehicle's OBD system and a network interface configured to perform network communications with a remote communications device connected with a vehicle scan and/or programming tool using a compatible pin-connector. The remote communications device includes a network interface configured to perform network communications with the vehicle communications device. The vehicle communications device is programmed and configured to receive communications from a vehicle's OBD system through its pin-connector and selectively filter communications based on message type received from OBD system. The selectively filtered communications are forwarded through a network to the remote communications device using the network interfaces.

A data processing system implements adaptive telemetry sampling by obtaining first telemetry data from a plurality of telemetry data sources, analyzing the first telemetry data to identify a subset of telemetry data sources for which a reduced sampling rate may be implemented, determining a reduced sampling rate for each event type of the plurality of event types, selecting a subset of the event types for which the reduced sampling rate is to be applied, obtaining second telemetry data from the subset of telemetry data sources at the reduced sampling rate associated with each event type of the subset of event types, analyzing the second telemetry data to determine one or more estimated metric values for one or more metrics, and generating a report comprising the one or more estimated metric values and an estimated total cost saving based on an estimated cost saving associated with each event type.

The embodiments of the present disclosure provide a transparency overlay method for a virtual set top box, a virtual set top box and a storage medium. Transparency layout features of a picture presented by an application scenario of the virtual set top box are acquired; whether compression processing of transparency data is allowed for each block on the picture is determined according to the transparency layout features; and compression processing of transparency data is performed on each allowed block, and transparency overlay is performed according to transparency data sampling points less than full number of transparency data sampling points in each allowed block.

In one embodiment, a method includes receiving a user input from a first user at the first client system, determining that the user input is a sharing request to share content, determining multiple second users the sharing request is directed to, determining, for each second user, modalities associated with the respective second user based on the content, a user profile associated with the respective second user, and modalities supported by a second client system the respective second user is currently engaged with, the respective second user being associated with two or more second client systems, and sending, to one or more second client systems currently associated with the second users, instructions for accessing the content based on the determined modalities for each second user.
