  • Patent number: 8989661
    Abstract: Methods and systems for processing data are disclosed herein and may include compressing audio information on-chip within a Bluetooth® transceiver chip utilizing an audio codec implemented within the Bluetooth® transceiver chip. The audio codec may be a low complexity sub-band codec (SBC). An audio stream with the audio information may be generated outside the Bluetooth® transceiver chip. The audio stream may be generated via an audio/video distribution transport protocol (AVDTP) external to the Bluetooth® transceiver chip. A data channel may be established by the Bluetooth® transceiver chip between a Bluetooth® enabled device and a peer Bluetooth® device, for communicating the established audio stream to the Bluetooth® transceiver chip for compression. The data channel may be established utilizing a logical link control and adaptation protocol (L2CAP) and/or an advanced audio distribution profile (A2DP).

  • Patent number: 8987933
    Abstract: A power over one-pair Ethernet approach. A data transformer is coupled to a single conductor pair using one or more direct current (DC) blocking elements that preserve an alternating current path. The data transformer enables a network device to transmit and receive data with a link partner device via the single conductor pair. Power transmission over the single conductor pair is enabled through the coupling of a power over Ethernet module to the single conductor pair using a diode that can be paired with a zener diode.

  • Patent number: 8990654
    Abstract: In conventional Backplane Ethernet systems, data is transmitted over two pairs of copper traces in one direction using a PAM-2 scheme and a baud rate of 10.3125 GHz, giving an effective bit rate of 10.3125 Gbps. The rate at which data can be transmitted in Backplane Ethernet systems, while still being reliably received, is typically limited by ISI caused by the dispersive nature of the copper traces, frequency dependent transmission losses caused primarily by skin effect and dielectric loss of the copper traces, and cross-talk from adjacent communication lines. The present invention is directed to systems for overcoming these and other signal impairments to achieve speeds up to, and beyond, twice the conventional 10 Gbps limit associated with Backplane Ethernet systems.

  • Patent number: 8989695
    Abstract: A wireless communication device is disclosed that is capable of transmitting emergency data to a base station even when the wireless communication device is out of range, or has insufficient battery life, to communicate with the base station using normal transmission means. When the wireless communication device is out of range or has low battery, the wireless communication device can transmit the emergency data to the base station by repeatedly transmitting the emergency data at a coding rate below a standard/minimum coding rate of the modulation scheme designated for use by the base station. The second wireless communication device can detect and decode the emergency data by storing the multiple transmitted iterations of the received signal and performing combining processing on those stored iterations.

  • Patent number: 8989263
    Abstract: The present invention provides an apparatus for performing inverse quantization for multiple decoding standards, where the functional operations that comprise the inverse quantizer are modularly implemented and can be selectably performed. Each operation can be represented via a table entry in an associated memory area, with the functional operation being performed via reference to that table entry. Functional operations can be bypassed as needed if inverse quantization does not need to be performed on a set of data. Certain other processing operations can be performed between steps as needed to accommodate different coding standards. Macroblock data can be read from and written back to a common storage area, or a direct path is provided for writing the data directly to a subsequent inverse transform device.

  • Patent number: 8989083
    Abstract: A method and apparatus is disclosed to restrict the delivery of video, audio, and/or data to unauthorized end users in a satellite communications system. The satellite communications system includes one or more satellite receiving antennas, commonly referred to as a satellite dish, to receive downlink communications signals from one or more satellites. The transmission received by the one or more satellite receiving antennas is converted by an outdoor unit (ODU) for transmission to one or more indoor units (IDUs). The ODU receives control information from one or more satellites from the downlink communications signals, commonly referred to as in-band, and/or from out-of-band communications signals. The ODU may use the control information to restrict access to one or more communications channels embedded within the downlink communications signals to the unauthorized end users.
