Abstract: A wireless power receiver includes circuitry configured to receive a wirelessly induced voltage from a wireless power transmitter via a magnetically induced connection with the wireless power transmitter. It is determined that an overvoltage condition exists when the wirelessly induced voltage exceeds a threshold voltage, and the wirelessly induced voltage is reduced in response to determining that the overvoltage condition exists. The circuitry communicates the overvoltage condition to the wireless power transmitter via the magnetically induced connection while over-voltage protection is enabled.

Abstract: A system for presentation timeline synchronization across audio-video (AV) streams associated with a common event may include memory and a processor. The processor may be configured to receive metadata items from a user device during a live event, the metadata items corresponding to points-in-time marked by the user while being presented with an audio-video (AV) stream associated with the live event. The metadata items may include timing indicators that are indicative of the marked points-in-time relative to the start of the live event. The processor may be configured to provide to the user device with other AV streams associated with the live event that were available at one of the points-in-time marked by the user. The processor may be configured to provide the other AV streams to the user device beginning with a frame that corresponds to the one of the points-in-time marked by the user.

Abstract: A wireless communication device (e.g., operative within a wireless local area network (WLAN)) coordinates with another wireless communication device to determine which communication parameter(s) to use in at least one FTM frame exchange. In an example of operation, the wireless communication device includes a communication interface and a processor such that the processor receives, via the communication interface, a fine timing measurement (FTM) request frame from the other wireless communication device. The FTM request frame specifies at least one preferred communication parameter for the at least one FTM frame exchange. The processor then determines, based on the FTM request frame, information related to the at least one preferred communication parameter. The wireless communication device generates and transmits a response to the FTM request frame to the other wireless communication device that confirms or overrides the at least one preferred communication parameter.

First processing circuitry is configured to receive a video stream encoded using a first encoding profile, transcode the video stream from the first encoding profile to a second encoding profile, and store the transcoded video stream in an output buffer. Second processing circuitry is configured to receive the transcoded video stream from the output buffer and decode the transcoded video stream according to the second encoding profile. The second processing circuitry may be unable to decode the video stream encoded using the first encoding profile.

In one example, a method includes determining a variable delay reference (VDR) corresponding to an instantaneous jitter between an idealized transmission time associated with a packet for transmission in a transmission stream and an actual transmission time of the packet and providing the VDR to a receiver in a sub-header of the packet. In another example, a transmitter includes a MAC configured to include a VDR in a sub-header of a packet for transmission in a transmission stream and a PHY configured to transmit the packet including the VDR in the transmission stream. In another example, a method includes receiving a packet in a transmission stream; extracting a program clock reference (PCR) and a VDR from the packet information; and controlling timing of processing of the packet based upon the PCR and VDR.

Abstract: A method and system are provided for architecture of a very fast programmable transport demultiplexer using a double-buffered approach. The method may involve utilizing a hardware assist block to process incoming packets, retrieve information about the packets, and write the retrieved information to a memory block. A firmware block may then utilize the information in memory to perform further processing on the packet data. The firmware and hardware assist blocks may work simultaneously so as to speed up the processing of the packet, which can comprise record data and/or audio/video data. The system may comprise the hardware assist block, the firmware assist block, and a memory block.

Abstract: A system includes baseband circuitry and a transmitter. The electrical behavior of the transmitter may cause distortion effects in the transmit output of the transmitter during transmissions based on input signals from the baseband circuitry. The baseband circuitry may reference a calibration evaluation function for multiple transmit variables to pre-distort the input signal to compensate for the distortion effect. Pre-distortion calibration logic may generate the evaluation function using a one-dimensional calibration technique. The evaluation function may facilitate the baseband accessing calibration data without necessarily relying on a look-up table. In some cases, a one-dimensional calibration for multiple transmit variables may use fewer calibration points than a similarly accurate multi-dimensional calibration.

Abstract: Embodiments provide systems and methods for selecting almost-blank sub-frames (ABSs) in wireless networks. ABSs may be utilized as part of enhanced inter-cell interference cancellation (eICIC). In an embodiment, an ABS pattern is selected in a distributed fashion without use of a direct interface between neighboring base stations. Embodiments operate with a hybrid self-organizing network (SON) that includes a centralized self-organizing network (cSON) unit and a distributed self-organizing network (dSON) unit. The cSON may provide the dSON with information about a plurality of ABS patterns, and the dSON may utilize the information received from the cSON to select an ABS pattern from the plurality of ABS patterns. In some embodiments, a base station may select neighboring base stations to perform eICIC based on a reference signal received power (RSRP).
