Abstract: A method including tracking a dynamic source ranking for a content provider separately by item categories of items of a content catalog. The method also can include receiving a new value to be associated with an attribute in an attribute-value pair for an item of the items. The new value can be provided by the content provider. The method additionally can include generating a priority score for the new value based on input features comprising the dynamic source ranking for the content provider for an item category of the item categories in which the item is classified, a confidence score for the new value, and an offer status of the new value. A first weighting associated with the dynamic source ranking and a second weighting associated with the confidence score are each greater than a third weighting associated with the offer status.

Abstract: A system for authenticating communications from a vehicle to a remote assistance unit includes a connectivity module (CM) installed in the vehicle. A security device is adapted to transmit messages when the security device is within a predefined proximity of the CM. A security cloud unit is configured to validate the security device based in part on a first pair of complementary keys, including a first factory key stored by the security device and a second factory key stored by the security cloud unit. The first pair of complementary keys is configured for asymmetric encryption such that the first factory key is solely decryptable with the second factory key. The remote assistance unit is configured to authenticate an integrity of the CM based in part on a second pair of complementary keys which are dynamically generated by the security cloud unit.

Abstract: A secure data path enables sending and receiving message applications to transmit instructions for recalling a sent message and updating or deleting content of the recalled message in an inbox of a recipient. In response to a recall request from the sending message application over the secure channel, since the receiving message application has access to a recipient inbox, the receiving message application may process the recall request to update and/or delete content of a received message—even after a recipient has read the received message. Since the content of a received message may be updated or deleted in a recipient inbox, robust and reliable message recall is provided.

Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus includes processing circuitry. For example, the processing circuitry obtains reconstructed samples in a temporal source frame that is different from a current frame, and determines filter coefficients of a filter for a current block in the current frame based on at least the reconstructed samples in the temporal source frame. The processing circuitry generates prediction information of the current block based on the determined filter coefficients. The temporal source frame is an inter coded frame that satisfies at least one of a quantization parameter (QP) requirement, a temporal distance requirement, and a reference picture requirement.

Abstract: Innovations in signaling of reference picture list (“RPL”) modification information. For example, a video encoder evaluates a condition that depends at least in part on a variable indicating a number of total reference pictures. Depending on the results of the evaluation, the encoder signals in a bitstream a flag that indicates whether an RPL is modified according to syntax elements explicitly signaled in the bitstream. A video decoder evaluates the condition and, depending on results of the evaluation, parses from a bitstream a flag that indicates whether an RPL is modified according to syntax elements explicitly signaled in the bitstream. The condition can be evaluated as part of processing for an RPL modification structure that includes the flag, or as part of processing for a slice header. The encoder and decoder can also evaluate other conditions that affect syntax elements for list entries of the RPL modification information.
