Abstract: A physical layer device comprises a transmitter of a first network device that transmits an autonegotiation signal to a second network device. A receiver of the first network device receives a received signal from the second network device. An autonegotiation controller autonegotiates link parameters for a link between the first network device and the second network device, monitors autonegotiation pulses in the autonegotiation signal relative to autonegotiation pulses in the received signal received during a window, and selectively blinds autonegotiation based on the monitoring.

Abstract: A first network device is provided in communications with a second network device comprising a physical layer device. The physical layer device comprises a transmitter to transmit an autonegotiation signal to the second network device, a receiver to receive a received signal from the second network device, and a controller comprising an autonegotiation controller to set a highest common data rate between the first network device and the second network device. The autonegotiation controller compares the autonegotiation signal and the received signal and selectively prevents the autonegotiation when the autonegotiation signal is the same as the received signal.

Abstract: A physical layer (PHY) device includes a first encoder that receives a first data stream at a first data rate, that encodes the first data stream using a first type of encoding, and that outputs first encoded data. A second encoder receives a second data stream at a second data rate different than the first data rate, encodes the second data stream using a second type of encoding different than the first type of encoding, and outputs second encoded data. An output selector outputs the first encoded data to a serializer of the PHY when the PHY transmits at the first data rate, and outputs the second encoded data to the serializer when the PHY transmits at the second data rate.

Abstract: A transmit path in a physical layer device comprises a first transmit encoding device that has N outputs, that receives a first data stream at a first data rate and that performs a first type of encoding on the first data stream. A second transmit encoding device has an output, receives a second data stream at a second data rate and performs a second type of encoding on the second data stream. The first data rate is N times the second data rate. An output selector has a first set of N inputs that communicates with the N outputs of the first transmit encoding device, a second set of N inputs that communicate with the output of the second transmit encoding device and N outputs. The output selector selectively connects one of the first and second sets of N inputs to the N outputs.

Abstract: An improved universal remote control unit (URC) for controlling electronic appliance units. The URC unit has the typical remote controller module for controlling appliances such as TV, stereo, VCR or DVD. Additionally, the URC has a scratch pad memory for storing telephone numbers and web site information entered through the URC unit's alphanumeric keys. When activated, the key pad entries are stored in the memory, instead of being used to control the appliance. The URC unit further has a digital recorder module that can be implemented with a microphone, a voice recorder chip and a speaker, all integrated with the URC unit. The digital recorder module can even use the battery that is typically used by the URC unit. The URC unit further has a display screen to display the information stored in and recalled from the memory.

Abstract: In an In-Flight Entertainment System (IFES), an audio distribution system transmits and synchronizes an audio data stream from multiple audio channels using the Adaptive Differential Pulse Code Modulation (ADPCM) technique for efficient transmission and preventing loss of synchronization. An encoder digitizes the analog audio signals, compresses the digital data, generates the synchronization parameters, including synchronization data for a selected channel, and creates a data frame to be transmitted to a number of decoders. Each decoder detects the synchronization header, extracts the compressed data patterns from the passenger selections, updates the ADPCM synchronization parameters, decompresses the compressed data patterns, and converts the digital audio data to analog audio signals to be delivered to the passenger seats.
