Abstract: A system including a modem locally generates a web page based graphical User interface for display to a user on a PC using different standardized browser applications and enabling a User to control or configure system functions. A processing system supports Internet compatible bi-directional communication and employs a method for providing local access to processing system parameters. The method involves receiving a locally initiated User command requesting access to a web page and validating authorization of the User command. The method also involves generating an Internet compatible web page for display containing a system parameter associated with the bi-directional communication in response to the validated User command.

Abstract: In a video signal processor including a motion compensated predictive coding data compression system, three adjacent image frames (1, 2, 3) are analyzed to detect a luminance gradient such as is typically associated with image fading. The frames are similarly divided into several segments (A . . . L). The sum of the absolute pixel value differences between corresponding segments from adjacent frames is obtained for each of two pairs adjacent frame segments (DIFF.sub.1-2 ; DIFF.sub.2-3). The ratio of the two frame differences (S) is obtained for each segment. Fading is indicated if the ratio remains substantially constant for all or a predetermined number of regions. If fading is detected, any motion vectors generated by the motion coder are assigned a zero value and are not coded.
