摘要： A still picture picturephone communication system for transmitting and receiving a still picture over a telephone circuit including a handshaking process wherein prior to still picture transmission, identification code data indicating a function of picturephone set is transmitted and received, and decision is made as to whether the still picture is being transmitted or not, wherein a designation code of a desired response waiting time within an identification code data used at the time of handshaking is formed, and the response is delayed by a period of time corresponding to the response waiting time, a still picture data is directly transmitted and received without handshaking, a character data including character information and the like is transmitted and received, manipurating a picturephone set on one party can be made a picturephone set on the other party to transmit a picture data therefrom, furthermore, the picture sent from the called party can be transferred to a third party.

摘要： A video optimized, low-cost modulator-demodulator is provided. Each modulated state or symbol (amplitude, phase, frequency or a combination thereof) has a one-to-one correspondence with a particular pixel value of brightness. For a black and white picture, adjacent shades of gray for the pixels are assigned to adjacent amplitude, phase or frequency values (in ROM 38) so that any error in transmission results in a pixel having its shade changed only slightly. A multiple amplitude, two-phase modulation method is preferably used. The black and white values are assigned to the highest amplitude level at opposite phases. As the pixel value becomes less black or white and more gray, it is assigned lower and lower amplitude levels with its phase being determined by whether it is closer to black or to white.
摘要翻译：提供视频优化的低成本调制解调器。每个调制状态或符号（幅度，相位，频率或其组合）与亮度的特定像素值具有一一对应关系。对于黑白图像，将像素的相邻灰度的灰度分配给相邻的幅度，相位或频率值（在ROM38中），使得传输中的任何误差导致具有其色调的像素仅稍微改变。优选使用多幅，两相调制方式。黑色和白色值被分配到相反相位的最高幅度电平。当像素值变得更少的黑色或白色和更灰色时，它被分配较低和较低的幅度电平，其相位由它是接近于黑色还是白色来确定。
