Abstract
An audio-video signal processor for use with a standard non-interlaced computer monitor has at least one video input for receiving an analog or digital input signal. The signal processor generates a resized non-interlaced video image, graphic video waveform, Lissajous (audio phase) and vector diagram based on the video input signal. Analog and digital stereo audio is also processed, and preferably multiple channel (i.e., 5.1 or 7.1) bar graphs including audio level and phase data are displayed based on the audio input signal. The signal processor simultaneously displays the resized non-interlaced video image, graphic video waveform, vector diagram, Lissajous (audio phase) and audio graphic display in progressive scan format, each in a portion of the standard non-interlaced computer monitor (e.g., SVGA, XGA . . . ).
