Abstract: Methods, apparatuses, and systems are described for determining network devices associated with old, incorrect, or conflicting internet protocol (IP) addresses. A determination may be made that multiple network devices are associated with an IP address. The network device that is supposed to be associated with the IP address may be determined. The association between the IP address and the other network devices may be discontinued.

Abstract: In an example method, a decoder obtains a data stream representing video content. The video content is partitioned into one or more logical units, and each of the logical units is partitioned into one or more respective logical sub-units. The decoder determines that the data stream includes first data indicating that a first logical unit has been encoded according to a flexible skip coding scheme. In response, the decoder determines a first set of decoding parameters based on the first data, and decodes each of the logical sub-units of the first logical unit according to the first set of decoding parameters.

Abstract: Systems and methods for dynamic bandwidth allocation and jitter handling in multi-tiered satellite networks such as virtual communication networks and/or physical communication networks. The system includes bandwidth distributing (BD) unit, in-route group managers (IGMs), in-route bandwidth manager (IBM). The system functions in multi-tier network entity management mode, and multi-beam management mode. The system operates by periodically collecting bandwidth reports from IGMs. The BD unit analyzes data in report and compares aggregated bandwidth demand with pre-defined thresholds. If thresholds are exceeded, system switches to multi-tier network entity management mode. In this mode, BD unit determines individual bandwidth adjustments for virtual network and beams and allocates bandwidth for individual devices within virtual network.

Abstract: Methods and systems for connection management are disclosed. A gateway device may provide services, such as a static IP service, to a user device via a first network.

Abstract: Techniques are disclosed for generating virtual reference frames that may be used for prediction of input video frames. The virtual reference frames may be derived from already-coded reference frames and thereby incur reduced signaling overhead. Moreover, signaling of virtual reference frames may be avoided until an encoder selects the virtual reference frame as a prediction reference for a current frame. In this manner, the techniques proposed herein contribute to improved coding efficiencies.

Abstract: A system may provide a voice user interface (VUI) for sending a media comment (e.g., brief clips of audio data representing speech) to a media content creator such as a podcaster, talk show, music app, etc. The system can identify a destination for the media comment based on context (e.g., an identifier corresponding to media content currently or recently output by a user device) and/or via voice dialog with the user. Content creators can invite, receive, and play users' media comments on the show, thereby increasing audience engagement. A media comment may include a request for or dedication of a song, a “shout out” to another listener, a story/opinion, a question, a response to a poll, a contest entry, etc.

Abstract: Selecting and presenting messages to user of an activity/health monitoring platform. The health/activity monitoring platform may receive physiological data for a user. The health/activity monitoring platform may identify a set of messages based on the physiological data. The health/activity monitoring platform may also determine a set of scores for the set of messages. Each score from the set of scores may be associated with a message from the set of messages and each score from the set of scores may be indicative of whether a respective message should be presented to the user. The health/activity monitoring platform may also identify a first message from a set of messages based on the set of scores and cause the first message to be presented via a display of a computing device of the user. The health/activity monitoring platform may also update a first set of penalties associated with the first message in response to causing the first message to be presented.

Abstract: Video coders and decoders perform transform coding and decoding on blocks of video content according to an adaptively selected transform type. The transform types are organized into a hierarchy of transform sets where each transform set includes a respective number of transforms and each higher-level transform set includes the transforms of each lower-level transform set within the hierarchy. The video coders and video decoders may exchange signaling that establishes a transform set context from which a transform set that was selected for coding given block(s) may be identified. The video coders and video decoders may exchange signaling that establishes a transform decoding context from which a transform that was selected from the identified transform set to be used for decoding the transform unit. The block(s) may be coded and decoded by the selected transform.

Abstract: Techniques are disclosed for coding video in applications where regions of video are inactive on a frame to frame basis. According to the techniques, coding processes update and reconstruct only a subset of pixel blocks of pixels within a frame, while other pixel blocks are retained from a previously coded frame stored in a coder's or decoder's reference frame buffer. The technique is called Backward Reference Updating (or “BRU”) for convenience. At a desired pixel block granularity, based on the activity between a current frame to be coded and its reference frame(s), BRU will only perform prediction, transform, quantization, and reconstruction on selected regions that are determined to be active. The reconstructed pixels in these active regions are directly placed onto a specified reference frame in memory instead of creating a new frame. Therefore, fewer memory transfers need to be performed.
