Abstract: A method for configuring a remote-control system includes querying via a bus a High Definition Multi-Media Interface (HDMI) display for an Extended Display Identification Data (EDID) for the HDMI display; receiving via the bus from the HDMI display the EDID for the HDMI display; and storing via a processor in a memory the EDID and a link between the EDID of the HDMI display a set of command codes configured for controlling the HDMI display.
Abstract: The present invention is a system and method for improving the audio quality during a in a living-room type of environment having multimedia equipment. In accordance with an embodiment of the present invention, the audio signals emanating from various speakers are modified/altered, so as to capture audio signals with the highest signal to noise ratio. One situation where embodiments of the present invention are usable is in the context of a video/audio call. Since the positions of the microphone and speakers are generally fixed, in some embodiments, the speaker outputs are controlled/modified to provide an improved signal-to-noise ratio. In accordance with one embodiment, the audio emanating from the central speaker is subdued or eliminated to reduce significantly the problems that occur due to the audio from the center speaker being captured by the microphone, which is typically in close proximity to the center speaker. The audio may be provided to the speakers by various ways, such as HDMI, RCA, and so on.
Abstract: A communication protocol in a wireless network of a transceiver and a plurality of devices, in which at least one device is a bidirectional device, and in which one or more other devices can be unidirectional devices. The unidirectional device communicates with the transceiver in a unidirectional mode from the device to the transceiver and the bidirectional device communicates with the transceiver either in a bidirectional mode or in an unidirectional mode from the device to the transceiver. The communication protocol is configured to determine which transmission mode is to be used for each device. Various techniques are provided in order to optimize the time and energy spent to transmit information from one peer to the other.

Abstract: A combination of techniques for modifying sound provided to headphones to simulate a surround-sound speaker environment with listener adjustments. In one embodiment, Head Related Transfer Functions (HRTFs) are grouped into multiple groups, with four types of HRTF filters or other perceptual models being used and selectable by a user. Alternately, a custom filter or perceptual model can be generated from measurements of the user's body, such as optical or acoustic measurements of the user's head, shoulders and pinna. Also, the user can select a speaker type, as well as other adjustments, such as head size and amount of wall reflections.

Abstract: A dynamic bass equalization circuit has an amplitude dependent gain that is dependent upon the audio electrical signal amplitude and a dynamically adjusted frequency response that varies with the amplitude dependent gain. In one implementation, the dynamic bass equalization circuit includes a Sallen-Key high pass filter that includes an amplifier with a negative feedback path. The dynamically adjusted frequency response is provided by a parallel pair of reversed diodes connected in the negative feedback path.
Abstract: A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

Abstract: A method for communicating video data between at least a first host and a second host comprises: identifying, at a server, an address of the first host, to which the second host may communicate video data, and a sequence number expected by a network security system coupled between the first host and the server; and communicating, from the second host to the first host, video data using the address of the first host and the sequence number expected. The method may further comprise: identifying, at the server, an address of the second host, to which the first host may communicate video data, and a second sequence number expected by a network security system coupled between the second host and the server; and communicating, from the first host to the second host, video data using the address of the second host and the second expected sequence number. The second host may be adapted to perform the act of communicating without use of an intermediate server.

Abstract: A personal audio device including a flexible headband is disclosed. The flexible headband includes a left and right headband portion. The headband has a longitudinal centerline which occupies a substantially single plane. The personal audio device also includes a left earphone, which is secured to a first end of the left headband portion, and a right earphone, which is secured to a first end of the right headband portion. A connector portion connects a second end of the left headband portion with a second end of the right headband portion. The connector portion is linearly adjustable, which enables a distance between the left headband portion and right headband portion to be variable. A change in the distance causes an inversely proportional change in bent compression force applied by a left earphone and applied by the right earphone.
