    • Reduction in the time required for an Advanced Television Standards Committee (ATSC) digital television tuner to equalize, converge, and acquire a digital television signal suitable for viewing, wherein early model ATSC tuners also include a National Television Standards Committee (NTSC) analog tuner, is achieved by using a microprocessor to control use of the NTSC tuner to scan television channels. A channel measurement module converts the scanned analog signal to a digital signal, and the equalization coefficients for the resultant digital signal are stored in memory. The equalization coefficients stored in memory are then accessed and utilized to tune in new channels on the ATSC tuner. The amount of time necessary for the ATSC tuner to tune in a new channel is thus reduced. When the ATSC tuner is in use, the equalization coefficient data stored in memory are periodically updated.

    • Training sequences designed for N-VSB systems within the embodiment of an N-squared QAM receiver facilitate designing 8-VSB receivers using methodologies of 64-QAM receiver design. A receiver designed using such methodologies converts the received modulation into a signal which can be accepted by circuitry for decoding 64 level quadrature-amplitude modulation (64-QAM) signals. This process provides a better signal to noise ratio reception than the conventional I-channel only decoding circuitry of most 8-VSB receivers. This process also employs training and equalizing algorithms developed for 64-QAM receivers which are superior to equivalent algorithms for 8-VSB receivers. The invention can be generalized to N-VSB conversion into M-QAM where M=N2. Adaptive equalization algorithms for 8-VSB transmissions implemented within the context of the 64 QAM receiver are superior to present single-channel VSP processing receivers. Present 64 QAM equalization strategies can be employed when receiving an 8-VSB waveform, given removal of the pilot tone and time offset, except when employing a training sequence. Modifications to the 8-VSB training sequence specification are employed for operation within a 64 QAM receiver design.
    • 在N平方QAM接收机的实施例中为N-VSB系统设计的训练序列有助于使用64-QAM接收机设计的方法来设计8-VSB接收机。 使用这种方法设计的接收机将接收到的调制转换成可由用于解码64级正交幅度调制(64-QAM)信号的电路接受的信号。 该过程提供比大多数8-VSB接收机的常规I信道唯一解码电路更好的信噪比接收。 该过程还采用为64-QAM接收机开发的训练和均衡算法,优于8-VSB接收机的等效算法。 本发明可以推广到N-VSB转换为M-QAM,其中M = N2。 在64QAM接收机的上下文中实现的用于8-VSB传输的自适应均衡算法优于目前的单信道VSP处理接收机。 当使用训练序列时,除了导频和时间偏移之外,当接收到8-VSB波形时,可以采用64个QAM均衡策略。 采用对8-VSB训练序列规范的修改用于在64QAM接收机设计中的操作。

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.

    • 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.

    • 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.
    • 修改现有的ATSC广播标准,以改善观众频道选择之后发现周期性发送的训练序列的速度和实现同步的速度到用于解码信号的均衡的连续宽带覆盖信号。 该修改涉及以与训练序列的传输同步的方式对导频信号进行轻微的幅度调制。 导频信号的调制足够小,可以被现有的ATSC接收机忽略; 也就是说,它是向后兼容的。 正确配备的接收机可以比没有配备的接收机更快地检测到通过解码该导频信号调制的训练序列的传输,从而能够在频道改变之后更快地向观看者提供解码图像,而不是没有配备的接收机。 此外,与已经提供用于均衡的连续宽带覆盖信号同步所需的时间被减少,如通过稍微改变调制以对应于周期性序列的特定相位部分的开始,例如用于 覆盖层。
