Abstract: An emulation device is used to stream media content from a digital media server to a digital media renderer. The emulation system receives a pulse code modulation data stream from the digital media server via a network interface, and stores the data in a buffer. The emulation system is attachable to the digital media renderer, and is recognized as a storage device containing an emulated media file. When the digital media renderer plays the emulated media file, the emulation device reads the PCM data from the buffer to use as sound or video data of the emulated media file.

Abstract: Systems and methods are provided to calibrate and compensate for signal impairments from the use of cables in data communication devices. Signal impairments such as intra-pair skew of differential signals and frequency dependent insertion loss are measured during a calibration phase. One end of the cable is connected to a communication device. The other end of the cable is configured to loop back calibration signals transmitted from the communication device. The calibration signals looped back from the communication device are received and measured by the communication device. The measured impairments are used to determine transmit and receive impairment compensation settings to compensate for impairments caused by the cable. These settings are stored and used to adjust signals transmitted from the communication device to compensate for the transmit impairment. These setting are also used to adjust signals received by the communication device to compensate for the receive impairment.

Abstract: A communication system and method is provided herein for synchronizing a plurality of network nodes after a network lock condition occurs within a network. According to one embodiment, the method may generate a local trigger signal simultaneously at each of the plurality of network nodes by compensating for unique phase delays attributed to each of the plurality of network nodes. As described herein, the local trigger signals may be used for synchronizing devices, such as multimedia devices, which may be coupled to the network nodes. More specifically, the local trigger signals may be used to synchronize events occurring within devices, which are coupled to different nodes of the network.

Abstract: Various techniques are provided to facilitate the identification of devices, such as high performance data communication devices, when such devices are connected over a data communication bus. In one example, high performance devices may identify each other by providing frequency modulated signal bursts which fall within a range of frequencies associated with a data communication standard. Similarly-implemented high performance devices may recognize patterns encoded in the frequency modulations of the signal bursts and thereby identify each other. Advantageously, while providing the frequency modulated signal bursts, the high performance devices may remain compliant with the data communication standard to facilitate communication with other types of devices which may expect to receive communications in accordance with the data communication standard.

Abstract: The transfer of media transmitted from a media provider from a first rendering device to a second includes establishing a network connection between the media provider and the second rendering device based on a network location and session context information. A desired transmission duplication of the media is determined such that the duplication will prevent substantial interruption of the rendering of the media as experienced by a user listening to both of the rendering devices, and that desired transmission duplication is sent to both the first rendering device and the second rendering device. The transmission is continued from the media provider to the second rendering device.

Abstract: A voltage regulator may derive current from a bias circuitry having a constant-transconductance. The bias circuitry may generate the bias current using three NMOS devices. The temperature coefficient of the bias current may be within a specified, desired range. The bias current may be mirrored to low-power regulator circuitry to bias a diode-connected transistor in the low-power regulator circuitry to operate in the strong inversion region. A ratioed current based on the output load current may be injected into a bipolar junction transistor (BJT) device to cause the gate-source voltage (VGS) of the diode-connected device to track the VGS of the output transistor of the voltage regulator, to ensure tighter load regulation. By operating the diode-connected transistor in strong inversion, by maintaining its (VGS) constant over temperature, and by cancelling the VGS of the output transistor of the voltage regulator with the base-emitter voltage (VBE) of the BJT device, the regulated voltage output may become free of the effects of temperature and supply voltage.

Abstract: Techniques are provided to serialize and delay parallel input data signals and are particularly useful for low power applications. In one example, a device includes a plurality of data input ports adapted to receive N parallel single-ended input data signals, and a clock input port adapted to receive a clock signal substantially synchronized with the parallel single-ended input data signals. The device also includes a cell adapted to serialize the parallel single-ended input data signals to provide N/2 first serial differential output data signals in response to the clock signal, delay the parallel single-ended input data signals, and serialize the delayed parallel single-ended input data signals to provide N/2 delayed second serial differential output data signals in response to the clock signal. The delayed second serial differential output data signals are delayed relative to the first serial differential output data signals. The device also includes a plurality of output ports.
