摘要： The present invention provides an improvement in a cathode-ray tube that includes a rectangular faceplate having two long sides and two short sides wherein the ratio of the length of the long sides to the length of the short sides is approximately 16 to 9. The tube includes a major axis which parallels the two long sides and a minor axis which parallels the two short sides. The improvement comprises the ratio of the equivalent radius of the faceplate curvature along the major axis to the equivalent radius of the faceplate curvature along the minor axis being in the approximate range of 1.5 to 1.6, the ratio of the equivalent radius of the faceplate curvature along the long sides of the faceplate to the equivalent radius of faceplate curvature along the major axis being in the approximate range of 1.12 to 1.15, and the ratio of the equivalent radius of the faceplate curvacute along the long sides of the faceplate to the equivalent radius of faceplate curvature along the short sides being in the approximate range of 1.30 to 1.36.

摘要： A main signal as the existing television signal and a helper signal for high definition are prepared in a transmitter. The energy of the main signal for a plurality of pixels is sequentially detected by an energy detector constituted by an absolute value circuit and an accumulator. The helper signal is controlled by a level controller, constituted by an adder and a divider, in such a way that its level follows according to the level of the detected energy. The level-controlled helper signal is frequency-multiplexed with the main signal having a frequency band of a removed region by a frequency multiplexer. A frequency-multiplexed signal separator of a receiver separates the mutiplexed signal into the main signal and the helper signal. The energy of the separated main signal for a plurality of pixels is sequentially detected by an energy detector constituted by an absolute value circuit and an accumulator. The separated helper signal has its frequency band restored to the original band from the removed region by a frequency domain restoring circuit. The restored helper signal is subjected to level control by a level controller, constituted by an adder and a multiplier, in the opposite characteristic to that of the sender side in accordance with the level of the detected energy.

摘要： Video signal information derived from a high definition source is conveyed via two channels. A first channel conveys relatively low spatial resolution, high temporal resolution video information compatible with a standard television receiver. An auxiliary second channel conveys relatively high spatial resolution, low temporal resolution video information. A high definition television receiver reconstructs original high definition information from the first and second channel information.

摘要： A widescreen television system includes an auxiliary subcarrier modulated with left and right side panel luminance and chrominance components. The chrominance modulating component represents the difference between the average side panel chrominance information and the original side panel chrominance information. Average left and right side panel chrominance information is respectively conveyed during the horizontal blanking intervals of alternate lines.

摘要： Apparatus and a method are provided for aligning an analog laser transmitter. Operational characteristics of the laser are determined. These characteristics are used to derive the power level required of a communication signal to properly modulate the laser for communication across an optical fiber. The magnitude of an input communication signal is then adjusted to the derived level, and maintained at this level for proper modulation. The alignment is performed upon the replacement of laser components in the field. The alignment may also be periodically effected to compensate for normal degradation of laser components over time.

摘要： A widescreen television system compatible with a lesser aspect ratio standard television system employs a panning operation using a circular-shift method to keep a 4.times.3 aspect ratio panning window (area of primary interest) centered for display purposes. Illustratively, when the panning window is shifted left by a given amount at the widescreen signal source, a corresponding portion of right sidepanel image information is "cut" and "pasted" alongside left sidepanel image information so that the panning window remains substantially centered with respect to side panel information. A reverse cut-and-paste operation is performed at a widescreen receiver to restore the original widescreen spatial format. A standard 4.times.3 aspect ratio receiver processes and displays the centered panning window information normally, unaffected by the panning operation at the widescreen signal source.
摘要翻译：与较小宽高比标准电视系统兼容的宽屏电视系统采用循环移位方法进行平移操作，以保持4×3宽高比平移窗口（主要感兴趣的区域）为显示目的。说明性地，当平移窗口在宽屏幕信号源处向左移动给定量时，右侧面图像信息的对应部分与左侧面图像信息一起被“剪切”和“粘贴”，使得平移窗口基本上保持相对中心到侧面板信息。在宽屏接收机上执行反向剪切和粘贴操作，以恢复原始宽屏幕空间格式。标准的4x3宽高比接收机处理并显示中心的平移窗口信息，不受宽屏信号源的平移操作的影响。

摘要： In a high definition multiplexed analog component system, a high definition signal is processed by splitting it into high and low frequency components and pre-emphasizing the high frequency component with a non-linear characteristic and at the receiver a complementary de-emphasis process is applied to produce a noise-reduced high definition signal compatible with existing conventional receivers. A processor of a pre-connector for the high definition signal can be used for intersample interference due to non-compatibility between the pre and de-emphasis characteristics in a digital implementation of the system.

摘要： Use is made of a digitally assisted DATV to effect a bandwidth reduction encoding and bandwidth reduction decoding, in addition to MAC-coding and MAC-decoding, of at least three picture signal channels (PC) each having a different picture signal refresh period equal to, for example, 80, 40 and 20 ms which are coupled via a time-division multiplex circuit (MUX). For with the diversity of picture signal sources, it was found that distinguishing during the picture signal processing between a film mode (SW1, T40) and a non-film mode (SW1, T20) results in a significantly improved high-definition picture resolution. This distinction is expressed at the DATV by one information bit (FM'). During the non-film mode (SW1, T20) three Y-liminance channels (PC11, PC13 and PC12) of 80, 40 and 20 ms and two U and V-chrominance channels (PC21 and PC22) of 80 and 20 ms are operative. During the film mode (SW11, T40) the Y-channels (PC11 and PC13) and the U and V-channels (PC21 and PC23) of 80 and 40 ms are only operative.
