In this test, the image has been recorded in 1080i, which the Blu-ray Disc player needs to reprocess as 1080p. The problem faced is the ability of the processor to distinguish between the still and moving parts of the image. If the processor does its job properly, the moving bar will be smooth and all of lines in the still part of the image will be visible at all times.

However, to through "wrench" into the test, the squares on each corner contain white lines on odd frames and black lines on even frames.

If the blocks continuously show still lines the processor is doing a complete job at reproducing all of the resolution of the original image. However, if the square blocks are seen to vibrate or strobe alternately in black and white, then the video processor is not processing the full resolution of entire image.

As you can see in this frame, the squares in the corner are displaying black. If you go back to the previous frame the same squares will be displaying white. This means that the lines in these squares are not being displayed properly as they are strobing between frames. On the other hand, although the rotating line was jagged in the previous photo, at the rotation angle shown in this photo, the line is fairly smooth. What this means is that farther the line is from the horizontal position on the image, the less jaggedness there is across the edges of the line.

For a look at how this image should look if the 1080i/1080p conversion is done properly, check out an example from an earlier review:

For a closer look at the jaggedness present on the bar as it rotates, check out a closeup by proceeding to the next, and last, photo in this gallery.
