Video display apparatus
First Claim
1. Video display apparatus for monitoring one or more user parameters of a user, the apparatus comprising:
- a television display apparatus having an input for an audiovisual signal and a screen display for viewing by the user;
a pre-recorded audiovisual medium having contained thereon a signal to be displayed on said screen display and at least one pre-recorded code signal;
a reproduction apparatus for reproducing from said medium a composite audiovisual signal;
a user parameter sensor apparatus for sensing electrodermal activity of a user and generating a signal representative of said electrodermal activity;
a signal modifying device connected to and interposed between said reproduction apparatus, said television display apparatus, and said user parameter sensor apparatus, the signal modifying device further having a means for detecting said at least one pre-recorded code signal and a means for modifying an output signal sent to the television display device by the insertion of an image over at least part of said screen display, said image being dependent on said signal from said parameter sensor apparatus in combination with said at least one pre-recorded code signal; and
a screen display modifier for deleting part of the image on said screen display wherein the part of the image deleted is responsive to said signal from said parameter sensor apparatus in combination with said at least one pre-recorded code signal.

Abstract
Video display apparatus e.g. for use in biofeedback or in diagnosis is described. Between an audiovisual reproduction unit such as a video cassette player and a television display, the invention provides a signal modifying unit which can cause the television display to change. The amount of change and optionally also its type may depend on the sensing of a user parameter, for example a psychophysiological parameter of the user or patient such as electrodermal activity. The signal modification device is preferably pre-programmed and microprocessor controlled. It may also react to coded signals embedded in the composite video signal recorded on the video cassette.
