ABSTRACT:
A test signal generator adapted to generate a test signal for an audio program having at least a left and right program track, the test signal generator including a memory means holding digital data descriptive of a unique image; and converter adapted to convert the digital data into a pseudo audio test signal having a left test track and right test track. The pseudo audio test signal is attached or mixed with the respective audio program and the resulting composite signal is recorded on a respective media and/or transmitted by other means to a remote location. At the remote location, the test signal is separated and displayed using the left track and right tracks as two orthogonal components to generate a reproduction of the image. The relative orientation, spatial and geometric characteristics of the reproduced image is indicative of various parameters of the received audio program.
