摘要： In a system for optimizing television reception by a television receiver receiving a diversity of input signals from a plurality of antennas, one of a plurality of combiners and television tuners selects the strongest combination of input signals for viewing and another scans the various combinations of input signals searching for a combination significantly stronger than the combination being viewed. A plurality of multiplexers selects the output signal of one combiner and transmits the selected signal to one of the tuners. A signal evaluation module evaluates the strength of the combinations of input signals and compares the strength of each combination of input signals to the strength of the viewing signal, looking for a superior signal. A control processor controls the combination of input signals selected by the combiners and the combiner output signal selected by the multiplexers. The control processor converts any superior signal found into the signal being viewed, at which time the process starts over and repeats.

摘要： The existing ATSC broadcast standard is modified to improve both the speed at which the periodically transmitted training sequence is found after channel selection by a viewer and the speed at which synchronization is achieved to a continuous wideband overlay signal used for equalization of the decoded signal. The modification involves slight amplitude modulation of the pilot signal in a manner synchronized with the transmission of the training sequences. The modulation of the pilot signal is sufficiently small to be ignored by existing ATSC receivers; that is, it is backwards compatible. Properly equipped receivers can detect, more quickly than receivers not so equipped, transmission of the training sequence by decoding this pilot signal modulation, thereby being capable of providing a decoded image to a viewer more quickly after a channel change than a receiver not so equipped. Additionally, the time required to synchronize to a continuous wideband overlay signal which has been provided for equalization is reduced, as by varying the modulation slightly to correspond to the start of a particular phase portion of the periodic sequence such as an m-sequence used for the overlay.

摘要： A video and audio capture and transmission system is described in which a “see-what-I-see” or “CWIC” view is possible. A camera and audio sampling circuitry are provided in an earpiece designed to be comfortably worn by a user. The earpiece may be tethered to a power and control unit, or may be wireless. Video and audio signals are transmitted to a receiver wirelessly, permitting a hands-free capture of video and audio signals. The signals are then transmitted to viewers, such as via management or control devices. Access to the overall CWIC system may be controlled both for content providers and for viewers.

摘要： DTV broadcast transmission is provided with a ultra wideband overlay signal which is used by suitably equipped DTV receivers to dynamically estimate the channel and allow expeditious and effective mitigation of changing multipath conditions. Periodic correlation peaks are detected in the received overlay signal, and the timing and magnitude of other peaks in the received overlay signal are used to mitigate multipath in the received signal. A DTV receiver that is not equipped to process the overlay transmission will not be significantly affected by the overlay signal.

摘要： A wide-band overlay sequence generator adds an overlay signal to a television signal which is transmitted through a channel. At a receiver, a replica of the transmitted overlay sequence is generated and synchronized to the overlay signal in the received signal. An adaptive equalizer filter effectively adjusts the received television signal so that the channel perturbations are removed from the signal.

摘要： An article includes a stack of display layers including a display layer having a high-shear modulus that is sandwiched between two display layers having a low-shear modulus. The display layers include a light-emitting device that generates heat and light during use. The heat generated by the display layers may form localized heat-sources in the stack. The display layer with the high-shear modulus is a thermal transport layer through which the localized heat-sources-induced guided elastic waves propagate along an acoustic waveguide plane and can transport the heat generated by the light-emitting device away from the light-emitting device. Alternately, a display layer having a high refractive index may be sandwiched between two display layers having a low refractive index. The display layers with low shear modulus or low refractive index may be replaced with thermal transport layers having low shear modulus or low refractive index respectively.

摘要： An Advanced Television Standards Committee (ATSC)-compliant pilot tone is generated within an 8-VSB (eight level vestigial sideband) transmission in order to enable Quadrature Amplitude Modulation (QAM) receiver designs to more efficiently process the transmitted/received 8-VSB signal. The method and apparatus also efficiently removes the pilot tone before using conventional QAM demodulator equipment for directly demodulating the 8-VSB signal.

摘要： An N-VSB (vestigial sideband) modulation signal is converted into an M-QAM (quadrature amplitude modulation) signal, where M=N2, by shifting the symbol rate frequency of a received N-VSB modulation signal to center the waveform spectrum about zero Hertz prior to complex demodulation so that data symbols will alternately appear on demodulated I and Q channels. A pilot tone of the received N-VSB modulation signal is removed to eliminate any bias in the both I and Q channels. Symbol timing between I and Q channels is offset, and quadrature amplitude demodulation of the I and Q channel signals generate alternating I and Q channel data symbols. Alternating inversion of the alternating I and Q channel data symbols recovers the N-VSB symbol data.
