Patent ID: 8031169

Claim:
A system for compensating for high-frequency attenuation of transmitted video signals, said system comprising: a user workstation of the type including a keyboard, cursor control device and monitor; an interface module; a communications link for providing video signals transmitted from a remote device and data signals transmitted from the remote device; a video receiving circuit in the user workstation for receiving said transmitted video signals from said remote device and for measuring amplitudes of a low frequency component and a high frequency-component of said transmitted video signals; a video signal analyzing circuit in the interface module coupled to said video receiving circuit for determining an attenuation of said high frequency component components of said transmitted video signals based on said measuring and for generating a control signal; and a video signal amplifying circuit in the interface module for amplifying the transmitted video signals to compensate for the amplitude attenuation of said high frequency component components of said the transmitted video signals in response to the control signal.
