Abstract:
1. A method for monitoring electronic transmission of an image comprising the steps of: electronically inserting a dynamic input test signal into an electronic source image to produce an electronic input image; supplying said input image to a processing circuit and, in said processing circuit, caching said input image in an image memory, as a cached image; in said processing circuit, generating an output image containing a dynamic output test signal, said output image being selected from the group consisting of said cached image and an image derived from said cached image, and emitting said output image from said processing circuit and displaying said output image; testing only said dynamic output test signal contained in said output image emitted from said processing circuit as to whether said dynamic output test signal corresponds to said dynamic input test signal; and generating a humanly perceptible notification if said testing indicates non-correspondence between said dynamic output test signal and said dynamic input test signal.
