According to the ffmpeg manual these are the definitions:
YMIN: Display the minimal Y value contained within the input frame. Expressed in range of [0-255].
YLOW: Display the Y value at the 10% percentile within the input frame. Expressed in range of [0-255].
YAVG: Display the average Y value within the input frame. Expressed in range of [0-255].
YHIGH: Display the Y value at the 90% percentile within the input frame. Expressed in range of [0-255].
YMAX: Display the maximum Y value contained within the input frame. Expressed in range of [0-255].
UMIN: Display the minimal U value contained within the input frame. Expressed in range of [0-255].
ULOW: Display the U value at the 10% percentile within the input frame. Expressed in range of [0-255].
UAVG: Display the average U value within the input frame. Expressed in range of [0-255].
UHIGH: Display the U value at the 90% percentile within the input frame. Expressed in range of [0-255].
UMAX: Display the maximum U value contained within the input frame. Expressed in range of [0-255].
VMIN: Display the minimal V value contained within the input frame. Expressed in range of [0-255].
VLOW: Display the V value at the 10% percentile within the input frame. Expressed in range of [0-255].
VAVG: Display the average V value within the input frame. Expressed in range of [0-255].
VHIGH: Display the V value at the 90% percentile within the input frame. Expressed in range of [0-255].
VMAX: Display the maximum V value contained within the input frame. Expressed in range of [0-255].
SATMIN: Display the minimal saturation value contained within the input frame. Expressed in range of [0-~181.02].
SATLOW: Display the saturation value at the 10% percentile within the input frame. Expressed in range of [0-~181.02].
SATAVG: Display the average saturation value within the input frame. Expressed in range of [0-~181.02].
SATHIGH: Display the saturation value at the 90% percentile within the input frame. Expressed in range of [0-~181.02].
SATMAX: Display the maximum saturation value contained within the input frame. Expressed in range of [0-~181.02].
HUEMED: Display the median value for hue within the input frame. Expressed in range of [0-360].
HUEAVG: Display the average value for hue within the input frame. Expressed in range of [0-360].
YDIF: Display the average of sample value difference between all values of the Y plane in the current frame and corresponding values of the previous input frame. Expressed in range of [0-255].
UDIF: Display the average of sample value difference between all values of the U plane in the current frame and corresponding values of the previous input frame. Expressed in range of [0-255].
VDIF: Display the average of sample value difference between all values of the V plane in the current frame and corresponding values of the previous input frame. Expressed in range of [0-255].
‘tout’: Identify temporal outliers pixels. A temporal outlier is a pixel unlike the neighboring pixels of the same field. Examples of temporal outliers include the results of video dropouts, head clogs, or tape tracking issues.
‘vrep’: Identify vertical line repetition. Vertical line repetition includes similar rows of pixels within a frame. In born-digital video vertical line repetition is common, but this pattern is uncommon in video digitized from an analog source. When it occurs in video that results from the digitization of an analog source it can indicate concealment from a dropout compensator.
‘brng’: Identify pixels that fall outside of legal broadcast range.

I think it would be helpful to compare the YUV Median values for a start ...
e.g.
ffprobe -f lavfi movie=HDV_0537.MP4,signalstats='stat=tout+vrep+brng' -show_frames
