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. . . ).

A testing device and method for a digital video processing system is coupleable to an input and output of the processing system, and inserts video and audio marking information into the input to test system operation. The test device inserts a video marker and an audio marker data code for a single audio channel, preferably in the same digital input frame. The device then monitors the same audio channel and also all the other audio channels at the output, while monitoring for the video marker. The device indicates the occurrence and timing of results that appear at the outputs, the relative timing of the output audio mark(s) versus the video mark, an alarm in the event that an output mark is not found or found on an unexpected channel, etc. The test device successively exercises the audio and video portions of the processing system while also providing numeric timing measurements that are useful for proper setup and operation.

An audio test device and method provide a visual display of audio parameters for plural audio channels. One audio channel at least temporarily is deemed a reference channel and other channels become relative channel for comparison. Samples from the reference and relative channels produce relative amplitude and relative phase difference values that are plotted on the display. The difference values for pairs of relative channel and reference channel data samples can be plotted as pixels in pie shaped plot segments or other two dimensional plots, one for each relative channel. The relative amplitude and phase differences are presented as positions of pixels along the axes of the plot. This arrangement is particularly useful in showing the current amplitude and phase condition of a multi-channel audio signal. In addition, the amplitude and relative phase data for the channels can be logged over a long time period (a day or more) to show the amplitude and phase conditions as changing over time.

A multi-format display device for video production and testing selectively presents a video input signal in three or more distinct ways to facilitate analysis. A complete picture, a picture zoom an area of particular scrutiny around a cursor position, tabular pixel information, a color swatch corresponding to pixel data values and graphic plots of picture data, audio and other information can be placed in areas of a formatted display. Predetermined or input pixel selection criteria can shift the display at least temporarily to identify pixels in the display that meet the criteria as the input video signal frames proceed.

The ultrasonic device which is sensitive to a selectably defined range for giving warning to a vehicle operator while backing which indicates visually an obstruction substantially out of range, close to range and within range coupled with an in range audio alarm giving an intermittent tone at a defined pulse rate which rate approaches non-pulsating as the object approaches within 25% of the selected range. A convex reflector of a defined radius in conjunction with angularly upright baffles disposed on the convexity is coupled to the transmitting/receiving transducer to generate an ultrasonic beam which encompasses objects anywhere in the range area adjacent to the vehicle's rear edge.
