Abstract: 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.

Abstract: 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.

Abstract: A multi-format display device for video production and testing presents a video signal in three or more distinct ways at different areas of a display, to facilitate analysis of video data for discrete areas within the video picture. A video processor produces a complete picture from the input signal on a limited part of the device display area, such as a quadrant of a digitally controlled standard display. At another limited part, preferably on the same display, a picture zoom is presented, showing a visual enlargement of a subpart of the picture around a cursor position, preferably large enough to point out individual pixels or data samples. A third part of the display presents a tabular form of specific pixel numeric data for one or more pixels at the cursor, and also produces a color swatch corresponding to the pixel data values. Graphic plots of picture data, audio and other associated information can be placed in remaining areas.
