Abstract: 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.

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.

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 . . . ).
