摘要： The frequency of a digital data signal, such as a digital video signal, is intentionally varied or hopped before being sent over a network. This frequency hopping may be performed in accordance with a frequency hopping pattern shared with only intended receivers. The digital data signal may be further intentionally pre-distorted in accordance with a pre-distortion pattern which is also shared with only intended receivers. The frequency hopping and/or the pre-distortion patterns may be used to vary the frequency and modulation, respectively, on a periodic basis, such as a symbol-by-symbol or packet-by-packet basis.

摘要： Antenna arrays are calibrated by providing one or more test signals from the antenna array to be calibrated to a receiving sensor while varying ambient operating conditions over some predetermined range of ambient operating conditions. The signal properties of these test signals may be measured by the receiving sensor or associated spectrum analyzer, and the ambient operating conditions under which the test signals are provided may be similarly measured. Thereafter, signal offsets for each of the antenna array's elements may be determined as a function of the measured ambient operating condition. Calibration information corresponding to these signal offsets may then be stored in a memory of the antenna array for use during operation of the antenna array. This calibration information may be in the form of a lookup table or a curve-fitting equation.

摘要： Methods and apparatus for optical wireless communication. In one embodiment, a wireless optical video system in which video content (e.g., DVI or HDMI) is transmitted wirelessly between a digital video source and a display device. This wireless optical communication is accomplished using a laser, encoded with the digital video data, directed from an optical transmitter to an optical receiver. In another embodiment, the data to be communicated includes high-definition video content.

摘要： A quantized channel rate and corresponding rate multiplier is determined on a transmitter-side of a communication system based on a measured minimum required bandwidth. In certain embodiments, the quantized data rate may be an integer multiple of the system's reference clock. The determined rate multiplier is then transmitted to the receiver-side at a default data rate prior to or near the beginning of a data transmission session, such as upon initialization. Prior to transmission, the data stream may be padded with some determined amount of null data such that the actual transmitted data rate is approximately equal to the quantized channel rate, and the receiver-side can readily recover the data clock using its known reference clock and the previously-provided rate multiplier.
摘要翻译：基于所测量的最小所需带宽，在通信系统的发射机侧确定量化信道速率和相应的速率乘数。在某些实施例中，量化数据速率可以是系统参考时钟的整数倍。然后，确定的速率乘数在诸如初始化之前的数据传输会话开始之前或之后以默认数据速率发送到接收机侧。在传输之前，可以用某些确定量的空数据填充数据流，使得实际发送的数据速率近似等于量化的信道速率，并且接收机侧可以使用其已知的参考时钟容易地恢复数据时钟，以前提供的速率倍数。

摘要： A TV-set is equipped with HDMI and USB connections that allow it to display and run audio-video content from a variety of conventional consumer devices. The TV-set is further equipped to provide a secure HDMI-USB interface that will allow the transfer of licensed high definition content and Internet subscriber services. Such secure HDMI-USB interface also enables a selection of proprietary application modules to be attached. Downloadable user interface templates, much like XML style sheets, are rendered to a user interface displayed on the screen. These are associated with corresponding thumbnails and URI's that allow a user to surf through lists and catalogs of materials, and then to play them in the appropriate formats and provide the machine with a customized controller. A remote commander is simplified, yet expanded to control all the attached devices through interactions with the user interface. The functions of the remote commander's keys change depending on where the user is navigating and what device is being controlled, similar to so-called soft-keys.
