Abstract: A disclosed example gateway node includes network communicator circuitry, memory, instructions, and processor circuitry. The network communicator circuitry is to send a first portion of a multi-part secret key to a first secret holder node, and send a plurality of shares of a second portion of the multi-part secret key to second secret holder nodes. The processor circuitry is to execute the instructions to combine responses from the first secret holder node and at least one of the second secret holder nodes to generate a combined authentication message, the network communicator circuitry to send the combined authentication message to a terminal node for authentication.

Abstract: A messaging server receives a sharing message from a sharer client indicating that the sharer client is offering to provide live location information. When the messaging server receives a subscription request from a receiver client indicating a request to receive live location information shared by the sharer client, the messaging server sends a location request to the sharer client. The location request requests live location information from the sharer client. The sharer client determines its location using a location module and sends live location information to the messaging server in response to the request. The server sends the live location information received from the sharer client to the receiver client. When no receiver clients send subscription requests, the sharer client does not send live location information, thereby preserving power by limiting use of the location module.

Abstract: Embodiments are disclosed for identifying duplicate stations in a radio station network. An example method includes identifying stations within a radio station network, determining which of the stations are duplicate stations, and selecting, via automated operated content management devices or user input directed to manually operated content management devices, which of the duplicate stations to show and which of the duplicate stations to suppress from being presented to a user. The example method further includes selectively displaying a selected duplicate station of a group of duplicate stations depending on a radio network's contractual agreements with various partners.

Abstract: Provided are a method and apparatus for encoding and decoding a stereo signal or a multi-channel signal. According to the method and apparatus, a stereo signal or a multi-channel signal can be encoded and/or decoded by generating parameters based on a mono signal.

Abstract: A computerized method and system for keeping popular advertisements active are provided. Example embodiments may include identifying one or more expiring online content from a plurality of online contents. A popularity of the one or more expiring online content may be determined; and an expiration date of the one or more expiring online content may be extended based on the popularity.

Abstract: Methods and systems may provide for using an adaptive entropy encoder to generate a compressed video signal based on an input video signal. Additionally, a compressed state signal can he generated based on the internal state of the adaptive entropy encoder. In one example, the compressed state signal is selectively incorporated into a data stream containing the compressed video signal.

Abstract: A method and apparatus for audio compression receives an audio signal. Transform coding is applied to the audio signal to generate a sequence of transform frequency coefficients. The sequence of transform frequency coefficients is partitioned into a plurality of non-uniform width frequency ranges and then zero value frequency coefficients are inserted at the boundaries of the non-uniform width frequency ranges. As a result, certain of the transform frequency coefficients that represent high frequencies are dropped.
