An audio display system can include an audio input configured to receive a plurality of inputs corresponding different audio channels of a multi-channel audio signal. A phase calculator is configured to determine a relative phase between at least a given pair of the audio channels. An amplitude calculator is configured to determine an amplitude for at least the given pair of audio channels. A display generator is configured to generate an audio display. The audio display can include an amplitude element representing the amplitude determined for each audio channel in the given pair of the audio channels, the amplitude elements being spaced apart from each other to define a phase zone between the respective pair of amplitude elements. The audio display can also include a phase output plotted in the phase zone between the respective pair of amplitude elements, the phase output representing a phase relationship between the given pair of the audio channels.

Multi-channel audio display

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.

Method and apparatus for analyzing digital video using multi-format display

A timing alignment or offset display shows the relationship between a reference signal and a test signal, in particular two analog or digital video signals. Timing extraction circuits derive a lower frequency signal synchronized to horizontal lines and a higher frequency signal synchronized to the pixel sampling rate. A reference time pulse is also derived from the reference signal. Two offsets are counted by determining a line count and a sample or clock cycle count between corresponding reference points in the test and reference signals. A coarse line count offset and a fine timing offset are thereby obtained and are displayed by movable markers on opposite sides of a scale line. The markers are centering and aligned when the frame/field alignment and the color and/or sample portions of the signals correspond in time. Tabular data, distinct coloring and alarms also are depicted.
