Abstract: A block of size N×M of a video frame can be either split into smaller blocks in n different ways (e.g. horizontal, vertical, quad, etc.), or alternatively it can be coded using one out of m different coding modes (e.g. intra, inter, bi-prediction, etc.). Since splitting into smaller sub-blocks and coding the N×M block in one of the m possible ways are mutually exclusive, there are n+m distinct possibilities for processing the block further. The n+m possible ways of processing the N×M blocks are assigned a code (e.g., a number) and coded with a codeword derived from a VLC table. This achieves efficient combined coding of split information and other block-level parameters.

Abstract: The present application discloses hearing prostheses with two modes of operation and methods for operating the prostheses. In the first mode of operation, a hearing prosthesis receives a microphone input and produces an output based on the microphone input. In the second mode of operation, the hearing prosthesis may detect an accessory input signal and switch to an accessory input mode. The second mode of operation may produce an output that is based at least in part on the accessory input signal. Some embodiments may include detecting an accessory input signal with a detector. In response to detecting an accessory input signal, the hearing prosthesis may switch to an accessory operation mode. When the accessory input signal is not detected, the hearing prosthesis may operate in microphone operation mode.

Abstract: One embodiment of the present invention provides a system for updating link-status information associated with a prefix in an information-centric network (ICN). During operation, a first node in the ICN receives a link-state advertisement (LSA) message from a neighbor node with the LSA message specifying a prefix and an anchor node advertising the specified prefix. The system determines, based on topology information stored on the first node, whether a shortest-path condition is met, and forwards the received LSA message to other neighbors of the first node in response to the shortest-path condition being met.

Abstract: Disclosed herein are methods, systems, and devices for selecting a scene classification for the operation of a sensory prosthesis, such as a hearing prosthesis. A system of two or more sensory prostheses can receive respective inputs from the environment of a recipient. A scene classification can then be determined for each sensory prosthesis based on the audio input received by each hearing prosthesis. A confidence value can also be determined for each scene classification. A scene classification can then be selected for each sensory prosthesis, from the determined scene classifications, based on the determined confidence values. Such operation can allow each sensory prosthesis to operate according to a respective selected scene classification that could be the same or that could be different from scene classifications selected for other sensory prostheses of the system.

The packet includes a bit string includes information identifying a plurality of destinations. The node selects an entry in a bit indexed forwarding table (BIFT). The BIFT includes both a primary path entry and a backup path entry. The node forwards the packet based on information in the entry.

Abstract: Presented herein are service-function chaining techniques that enable data plane signaling of a packet as a candidate for capture at various network nodes along a service function path of a service function chain. That is, a capture signal is embedded within the respective packet that carries a user traffic. The signaling occurs in-band, via the data plane, such that classification of the packet for capture beneficially occurs, at the ingress node of the network, once to which subsequent network nodes along a service function path are signaled to capture or further inspect the packet for capture. Service function chaining treats service functions as resources with associated attributes available for scheduled consumption to which selective traffic are steered according to a policy construct to the requisite network-service resources.

Abstract: In a transmit method, a set of data eigenvectors that are based on a Prometheus Orthonormal Set (PONS) code construction and orthogonal to each other are stored, wherein each of the data eigenvectors is mapped to a unique multi-bit word. A pilot sequence representing a pilot eigenvector that is based on the PONS code construction and orthogonal to each of the data eigenvectors is generated. Input data is grouped into multi-bit words and ones of the data eigenvectors mapped to the multi-bit words are selected. A spread data sequence including the selected ones of the data eigenvectors and that is synchronized to the pilot sequence is generated. An acoustic signal including the synchronized pilot sequence and the spread data sequence is generated. The acoustic signal is transmitted.

Abstract: In one embodiment, a time period is identified in which probe packets are to be sent along a path in a network based on predicted user traffic along the path. The probe packets are then sent during the identified time period along the path. Conditions of the network path are monitored during the time period. The rate at which the packets are sent during the time period is dynamically adjusted based on the monitored conditions. Results of the monitored conditions are collected, to determine an available bandwidth limit along the path.

Abstract: Large source data packets having large packet sizes and small source data packets having small packet sizes that are smaller than the large packet sizes are received. The small source data packets and the large source data packets are sent to a receiving device without forward error correction (FEC). The small source data packets are aggregated into a container packet having a header configured to differentiate the container packet from the large source data packets and the small source data packets. The large source data packets and the container packet are encoded with forward error correction to produce FEC-encoded packets to enable forward error correction of the large source data packets and the container packet at the receiving device. The FEC-encoded packets are sent to the receiving device.

Abstract: In one embodiment, multicast packets including, but not limited to, Bit Index Explicit Replication (BIER) multicast packets, are forwarded in a network. An independent lookup operation is performed on each destination node identified in the received packet to determine a nexthop to which to forward a copy of the packet. Typically, some or possibly all of these lookup operations are performed in parallel, in contrast to the sequential lookup and bit masking operations of previous BIER packet forwarding specifications and implementations. In one embodiment, the selection of a nexthop for a destination node is made from a set of two or more nexthop nodes on different Equal-Cost Multi-Paths (ECMPs). In one embodiment, compact data structures are used in determining how to forward the received multicast packet, with these compact data structures providing requisite forwarding information without allocating space to unassigned destination nodes.

Abstract: A content-dissemination system distributes, publishes, or makes available a content item to one or more target entities based on contextual information associated with the content item. When a user creates a new content item or the system detects a new content item for a local user, the system determines contextual information for the content item, and uses this contextual and previous historical contextual information to generate a set of structured names for the content item. The system also determines security and privacy policies for disseminating the content item from the determined contextual information and the historical contextual information. The system associates the set of structured names and the security and privacy policies with the content item, and can disseminate the content item to one or more target entities based on these structured names, the security and privacy policies, and the requirements and capabilities of the recipients.
