Abstract: A defective pixel tester determines defective pixels within a digital video camera. The tester includes a video input, a memory and a controller. The video input receives video frames from the digital video camera, with each video frame defined by a plurality of pixel values. The memory stores captured video frames and pixel test results. The controller generates difference values for corresponding pixel values from different video frames, generates pixel test results based upon a comparison of the difference values to a threshold, and stores the pixel test results in the memory.

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: 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.

Abstract: 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.

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.
