Abstract: A universal serial bus (USB) extension allows for the transmission of data at high speeds over a much greater distance than typical USB operating range. USB devices (116-1, 116-2) may be connected to a host computer (102) at distances of 750 meters or more. USB tokens from a host computer (102) are spoofed.
Abstract translation: 通用串行总线(USB)扩展允许以比典型USB操作范围更远的距离高速传输数据。 USB设备(116-1,116-2)可以在750米或更远的距离处连接到主计算机(102)。 来自主机(102)的USB令牌被欺骗。

Abstract: A video compression system compresses video frames comprising pixels defined by n-bit color values. Encoder of video compression system determines the difference between a current pixel value and a plurality reference pixel values. Encoder sends difference value to decoder. Decoder determines current pixel value by adjusting a reference pixel color value by delta value.
